Samsung Galaxy A72 : A Perfect Mid-Range Smartphone of 2021

0

Starting in 2021, Samsung has released many types of smartphones in different segments. However, unlike the previous year, the middle or mid-range series was the slowest or last release, after flagship and entry-level. Including the Samsung Galaxy A72 which was released at the same time as two other A series in the country.

Compared to the Galaxy A32 & Galaxy A52, of course the Samsung Galaxy A72 is a form of the most premium offering among the three. The design is made different from the previous series, looks more like a flagship line, and actually carries the DNA that should have been brought from the Galaxy A series a few years ago, namely waterproof certification.

To be honest, at first I was skeptical of the presence of the Galaxy A72, where I felt it was worth buying the Galaxy A52 variant only. But after a few days of using it as a daily driver, my perspective changed. Here is a complete review of the Samsung Galaxy A72

Design

When I first saw the rear body of the Samsung Galaxy A72, I immediately remembered the Galaxy Note 20 Ultra. Maybe because the shape of the camera module is very similar, and the four corners are a little firmer or boxy. Including the dimensions which are quite large, and have a steady weight at 203 grams.

Not the lightest, and certainly not the thinnest at 8.4mm. The material also uses plastic with a matte surface. Of the four color variants, the Awesome Black color that I reviewed is quite attractive and is able to hide fingerprints, aka not easily dirty.

Without a soft case in the sales package, the unit still looks smooth including the bezel which has a chrome accent, even though I use it & place it rather haphazardly. So that for durability, it’s good enough and you don’t need to worry even though it’s not made of glass or metal material.

Dirty? Just watered it with clean water, because Samsung again gave it IP67 certification. Aliases are dust and water resistant to a depth of 1 meter for 30 minutes. Even the 2021 flagship still exists without an IP rating. So it is quite surprising that Samsung decided to return to this feature (including the Galaxy A52).

Display

For the screen, maybe you could say there is an up and down. The Samsung Galaxy A72 has an extra-wide screen with dimensions of 6.7 inches, which of course already uses a Super AMOLED panel. Of course the contrast and color saturation are very good (slightly higher than the Galaxy S20 FE though). What’s new from the previous generation is the implementation of a high refresh rate.

Yes, this time Samsung’s middle-class smartphone users can enjoy smooth transitions when scrolling or access content on the screen up to 90Hz, even though it’s not yet adaptive which can save more battery. Besides that, I have no problem with the flat panels. It’s just that, for the size of a smartphone, the price is Rp. 5 – 6 million, the four bezels are too thick.

With an already large screen, the bezels are slightly thicker than the previous generation making the overall dimensions even bigger. Although, indeed, for those with small hands, there is a one-handed mode to make one-handed navigation easier. The punch-hole camera looks very small and is in the top center, with silver accents around it.

Camera

The Samsung Galaxy A72 camera setup is exactly the same as the Galaxy A71. There’s a 32MP sensor at the front, a 64MP f / 1.8 main sensor with Quad Bayer technology, 12MP ultra-wide angle and 5MP macro. The two main differences are in stabilization, and the replacement of the depth sensor into a much more specialized sensor.

For the first time, in the A7 series, Samsung has embedded an 8MP f / 2.4 telephoto sensor with PDAF and 3x optical zoom. This sensor can provide a maximum zoom of up to 30x, much like the Galaxy S21. What’s more, both the main sensor and the telephoto sensor are also equipped with OIS.

In terms of features, it is not much different from other Samsung mid-range series. There is a Pro Video mode, there is a watermark option (which is still too big), and also a Single Take mode which is more flexible. Plus a new mode, “Fun” which is like a Snapchat filter integrated in the camera application.

So what about the camera results? I myself have never tested it with the previous generation, but the impression is better than the Galaxy M51. Color reproduction tends to be accurate and not over-saturated. The quality of the ultra wide-angle sensor is also of high resolution quality — it’s just that night mode can’t be used with this sensor.

The existence of a telephoto sensor makes me more often take photos from a distance or detail objects closer. Just like in other smartphones, this sensor is only used in sufficient light conditions. Exceeded my expectations, an experience not found in smartphones with the same price.

Both the front and rear cameras of the Samsung Galaxy A72 can record videos at up to 4K 30fps. And for 1080p video recording on the rear camera, users can change the sensor subtly during the recording process, from ultra-wide to telephoto. A complete package for creating quality video content from a smartphone.

Other Features

Using the latest One UI interface, Samsung promises an attractive update system in the A series this year. For the Samsung Galaxy A72 & A52, it promises three times Android version updates and four years of security updates. Although in some applications such as the weather is now advertising.

Features such as Game Launcher and Edge Panels are here to make it easier for users to play games and access certain features or applications. There’s also less bloatware, with Bixby shortcuts being optional and the Samsung browser app also not required to be installed.

Even though it is now waterproof, Samsung has pinned a dual speaker setup, where the Samsung Galaxy A72 earpiece is now active as a secondary speaker. What is somewhat lacking in my opinion is the less precise haptic feedback or vibration, and the fingerprint sensor which is not as instant as competitors. Reliable, but it takes extra time for the screen lock to unlock.

Processor

The chipset used on the Samsung Galaxy A72 is very common in its class. It may look numerically as a downgrade, the Snapdragon 720G is still superior to the Snapdragon 730 on the Galaxy A71.

Combined with 8GB RAM and 128 / 256GB internal storage, I say the performance is sufficient. It’s not slow, but I sometimes encounter stuttering or less smooth transition effects when switching applications. Maybe because the refresh rate is high, so it is more burdensome for processor performance.

The rest is okay, it is used for intensive camera testing and it doesn’t feel hot either in the rear body and in the camera module area. Oh yes, the SIM slot on this smartphone is of a hybrid type, so make sure the internal memory capacity you choose is right if you want to use it with two nano SIM cards.

Battery

The Samsung Galaxy A72 battery capacity is slightly enlarged from the previous series, now 5,000 mAh. Maybe that’s the reason why this smartphone appears a little thicker. For intensive use of my a-la, enough for one full day of use with screen on-time reaching 4.5 – 5 hours.

That includes an active always-on display as well as activating the hotspot for more than an hour, including testing the camera and the 90Hz refresh rate. If it’s lighter, the Samsung Galaxy A72 can definitely go beyond at least 1.5 days of use. Charging is also quite fast with 25W fast charging via the USB-C port.

I think Samsung has upgraded the Galaxy A72 class to a higher level. Looking for ways to make as many flagship features as possible be felt by more people, cutting out unnecessary extra features. Glass body, wireless charging, curved screen, and others are not found on this smartphone.

But the Samsung Galaxy A72 carries essential flagship features like main sensor (& telephoto) with OIS, IP certification rating, 90Hz AMOLED panel and still combines it with a microSD card slot plus a 3.5mm audio jack. Reaching a combination point that fits perfectly in its price class, fits into the first choice.

Huawei FreeBuds 4i : The Perfect ANC Buds with Amazing Sound Quality

0

Even though Huawei smartphones come with limitations such as the absence of Google services, a similar condition is absent from this one electronic company released by this Shenzhen-based electronics company. Not only the premium series, Huawei also presents affordable device options. Like the Huawei FreeBuds 4i which was recently launched.

The previous generation FreeBuds 3i gave me a distinct impression. For a TWS earphone that supports ANC in the millionth price range, the quality exceeds my expectations, from audio quality to design quality. Now Huawei has perfected it with a longer battery life, and a sweeter and more comfortable design.

Launched together with the Huawei Watch Fit Elegant Edition, the Huawei FreeBuds 4i certainly has its own charm. Even after only 1-2 days of using it, I can already say that Huawei’s latest TWS is worth buying. And here is the full review.

Design

Even though the build quality is quite good in its class, what I regret from the previous generation is that the size of each earbud is too big. This issue has been fixed by Huawei through FreeBuds 4i, where the earbuds are designed to be more compact, as well as the charging case.

No longer a pill shape, the Huawei FreeBuds 4i charging box is made smaller and oval, with a curved design that is more like FreeBuds 3. As a result, it is easier to carry in a bag or trouser pocket. There are three color options to choose from; Ceramic White, Carbon Black and Honey Red.

Both the surface of the case and the earbuds still use a glossy surface, easy to clean but also easy to imprint fingerprints. While the weight itself is still the same, 5.5 grams per earbud, it’s still comfortable to use for long. In addition to the eartip that is already installed, Huawei provides two extra sizes in the sales package.

IPX4 certification makes it splash or sweat resistant when used for sports. The mechanism for placing the earbuds into the case also uses magnets – unfortunately, after about a week of use, I still had trouble getting the earbuds out of the case. It’s just slippery, so it takes extra effort. The rest is no problem.

Features

The star in this section is the active noise cancellation or ANC feature. Just like in the previous series, Huawei FreeBuds 4i utilizes more than one microphone to detect inner and outer sound, to present two features at once.

In addition to the off mode, there are “noise cancellation” and “awareness” modes that can be activated via touch gestures. The first mode can effectively block outside noise, so you can focus more on working or listening to music in a crowd.

If you are in a crowd such as a busy road, the noise you hear is only thin and can still be tolerated. Meanwhile, in order to stay safe when exercising outside or public transportation, the second mode can be activated so that outside sounds can be heard. Can also be activated when you want to talk without removing the device.

Then what if it is used for Zoom calls or other telephone purposes? The microphone of the Huawei FreeBuds 4i is quite reliable – when I use it in a cafe with moderate background music, the second party doesn’t hear it and my voice is quite clear (although it has to be a little loud).

How To use

Huawei FreeBuds 4i can be connected easily to several devices ranging from Android smartphones, iOS to computers. Entering pairing mode, you only need to hold the button on the right side of the case until the indicator light outside turns white.

Once connected, switching between devices can be done instantly, without the need to disconnect from the currently connected device. In other words, it supports seamless connectivity which is rarely present in its price range. It’s just that, the gesture options are limited to double-tap and touch-and-hold.

When paired with Android or iOS, Huawei provides the AI ​​Life application where you can do software updates, and customize shortcuts even for each earbud. For reliability or smoothness of sound, it is much better than FreeBuds 3i, although sometimes there are glitches when passing through areas of tall buildings.

Oh yes, even though it supports wear detection, this feature is exclusively present when Huawei FreeBuds 4i is paired with a Huawei smartphone running EMUI 10. So that when paired with another device, the song being played cannot automatically stop when the earbuds are removed from the ear.

Sound Quality

The sound output from the Huawei FreeBuds 4i. Just like the previous series, this device is designed to be able to deliver a powerful, balanced high, mid and low performance. So that there is no warm or dominant sound of one particular audio variable.

With a 10mm diameter dynamic driver in each earbud, this device is specially designed for pop music with instruments and vocals balanced. At least that’s what is written on the official website, even though in reality it fits a wider range of genres.

Listen to the acoustic version of HiVi! Or Gleen Fredly fits perfectly. And if you want to listen to IDM songs or a kind of Inikah Cinta from Soundwave, surprisingly the bass output is powerful, it doesn’t even break when the bass variable from the equalizer is increased.

Huawei FreeBuds 4i battery
One of the most enhanced features on the Huawei FreeBuds 4i is its battery life. With a 215 mAh battery in the case and 55 mAh in each earbud, the total music playing time is up to 22 hours. If it sounds ordinary, what’s special is the one-use durability of up to 10 hours.

If the duration does not use ANC, yes, if it is activated it drops to a range of 6 – 7 hours. Fully charging this device takes approximately two hours via the USB-C port. Fast charging support is also present on the Huawei FreeBuds 4i, enough to charge about 10 minutes to listen to music for up to 4 hours.

Complete Details of Realme C21 with Design, Display, Processor, Camera and Battery

0

The Realme C series is well-known as a series that offers large batteries at affordable prices which is known to have successfully attracted smartphone users in its price range.

Well, the realme C21 itself is the C series with a large battery, three cameras and high quality, armed with certification from TUV Rheinland in the price range of one million.

This TUV Rheinland quality certification is the first time there is for an entry-level smartphone like the Realme C21. The vendor chose TUV Rheinland High Reliability certification because he wanted to set new quality standards in the entry level segment.

Not only that, to accommodate the needs of realme users in the beginner class segment, the C21 Realme is also supported by a camera and battery that can compete in its class.

Design

Regarding design, the exterior of this smartphone is attractive considering that the C21 realme enters the entry level segment. Apart from having an eye-catching appearance, vendors are elevating the design sector on this smartphone to a higher level.

Realme and the quality testing team at TUV Rheinland work together to set new, improved quality standards for smartphones. TUV Rheinland has successfully set high quality standards for consumer electronics as well as industry standards for major markets worldwide.

According to TUV Rheinland’s new quality certification standard, most test conditions are based on the smartphone’s three-year life cycle.

TUV Rheinland conducts 23 tests covering 10 daily use scenarios including drop and abrasion due to use tests, then 7 extreme environmental scenarios such as super high and low temperature, high and low humidity, voltage fluctuation and static electricity.

Finally, there are 6 component testing scenarios such as the power and volume buttons and charger holes.

As a result, this affordable built quality smartphone can be transformed in such a way to be tough and premium. This C21 realme also has a camera module designed in the form of a box as well as a fingerprint sensor on the back.

It looks pleasing to the eye with a geometric design inspired by an hourglass, comfortable to hold and minimal fingerprints. The textured back is processed using the latest technology from Germany with a five-axis precision engraving machine that prevents scratches.

this series has three card slots (2 SIM + 1 microSD up to 256GB). It has a 3.5mm audio port on the bottom area and a microphone hole. Then the volume and power buttons are located in a row on the right side.

The latest design is presented by Realme C21 by placing speaker holes on the back of the body to produce a bigger sound output. It is said that according to a realme survey, this entry-level smartphone user needs a large sound output more.

Display

This latest realme smartphone carries a 20: 9 mini drop screen with a span of 6.5 inches. This field of view is comfortable for playing games and watching videos. Moreover, the internal structure of the Realme C21 screen adopts a new arrangement process.

Realme creatively draws parts and components closer to each other resulting in reduced bangs area and delivers a screen ratio of up to 89.5% which has less visual distraction especially when watching multimedia content.

This series uses an IPS LCD panel with a resolution of 720 x 1600 pixels or so-called HD +. It is quite satisfying that we can enjoy a fairly sharp screen image display with optimal brightness.

Camera Setup

Realme C21 uses a main camera that adopts a 13MP image sensor with a large area. Supplied with a relatively large aperture of f / 2.2 to secure light and aid shooting in low light conditions.

this camera is backed up with PDAF which is able to capture focus more quickly and precisely. Then there is also the 4x zoom feature which also allows users to take clear photos from a distance.

Complementing the main sensor, there are B&W and Retro lenses providing two special artistic effects for portraits. Both lenses can reproduce portraits in black and white, providing high exposures and enhancing contrast.

As a complement, this C21 realme also deliberately brazed a macro lens with a super close shooting distance of 4cm. So that we can shoot macro photography with good detail. Not bad for exploring the charms of the micro world.

For selfie enthusiasts, there is a 5MP selfie camera on the front. Already supports AI beauty, HDR mode, portrait mode and the Panoselfie feature to help you take wider selfies.

Performance

This realme C21 is enhanced with the MediaTek Helio G35 chipset. Supported by an octa core core so that its performance is quite capable even though it is present for the entry level segment.

For those who are curious, the Mediatek Helio G35 is an eight-core processor with a 12nm fabrication capable of reaching a clock speed of 2.3 GHz, and adopting the Cortex A53 structure.

This processor is ideal for general users and gamers as it can handle most of the commonly used medium and heavy applications.

Convenient for playing the Mobile Legends game, you can still use high or high graphic settings. For PUBG Mobile, the graphics settings are just medium. Gameplay is still satisfying, there is no significant lag.

realme C21 will be available with 3GB + 32GB and 4GB + 64GB variants which are powered by LPDDR4X RAM. Compared to LPDDR3, graphics performance has increased by 20% and RAM performance has increased by 100%.

Android Version

realme UI based on Android 10, is better built closer to the pure Android interface. realme designed the UI keeping the preferences and aesthetics of young consumers in mind. The interface is smooth and efficient when used.

There are various features such as Dual Mode for sharing music, being able to connect a pair of wireless earbuds and wired earphones at the same time. There is a Focus Mode which can help you concentrate and relax, without being distracted from your phone.

Just use 3 fingers, press and hold on your screen then swipe to capture the selected part of the screen. There’s no need to cut anymore. Taking partial screenshots is done with just one step.

By enabling “Personal Information Protection” in realme UI, the system will provide a blank information page when the application requests to access the user’s personal information such as call history, contacts and messages.

Finally, there is a built-in Dark Mode which is neatly integrated in the realme UI. This mode is optimized to work in more third-party applications.

Even though it is an entry level product, the C21 realme supports an ultra-fast fingerprint sensor. Also supports facial recognition to make it easier to unlock with one click or one glance at the face.

Battery

It’s no secret that the battery plays an important role in today’s smartphones. People who have high mobility with as stable activities are likely to be suitable for the C21 reality.

The C21 realme that we tested had a 5000mAh battery. So, with a jumbo capacity like this, we can do outdoor activities all day without bothering to carry a charger.

In fact, this smartphone can become a power bank and help charge smartphones and other gadgets thanks to the OTG Reverse Charging feature. So besides being durable, the battery power can even be transferred to other devices.

Based on testing at Realme Lab, Realme C21 can last for 47 days in standby mode. Still about the battery, Realme also presents a Super Power Saving Mode.

In this mode, you can select 6 most used applications to stay active to extend a very long battery life.

When this mode is activated, the smartphone will automatically implement a more aggressive power saving strategy. According to realme’s research on user behavior, most people only use these 6 apps in 70-80% of all smartphone time.

So, we believe the super power saving mode greatly improves battery life but without sacrificing daily use.

Furthermore, the C21 realme relies on a 10W charger as a means of charging the battery. It takes about 3 hours to recharge the battery of the C21 realme.

Dual LAN : Amazing advantages of a board with two Ethernet ports

0

Dual LAN motherboards are quite common in the high-end home range, as well as professional-grade products. In this article we will review what it means to have dual Ethernet and in which cases it is usually used. In general, we will see quite beneficial situations for those who want to take advantage of a powerful local network to the maximum.

What is dual LAN exactly

Every current motherboard has at least one card or network controller, also called NIC (Network Interface Controller), from which the Ethernet connection that we will see in it comes out. But, as we say, we found precisely ” at least ” one, being common that there are motherboards with two NICs. This is how Dual LAN is achieved, plain and simple using two different network cards on the board. They can be of the same model, but of course there will be two different ones.

Depending on the user, this will be more or less relevant, and its number of benefits will change. In the article we will analyze to what extent it is an interesting addition, since it must be taken into account that these NICs are usually very cheap, so even if it is not really useful, the manufacturer may not care to include it in order to differentiate itself. When something like this happens, there is a kind of domino effect, because other manufacturers also start to use it even if it is not necessary.

On the other hand, another issue that must be taken into account is that it is common for two different NICs to be used , as indicated before. So, we could benefit from that difference, in addition to the fact that a network card could support much more powerful connections (for example, a card can have 1 Gigabit / s Ethernet and another 10 Gigabit / s).

Some of the most useful advantages of Dual LAN

The most exploited advantage in dual LAN is to use a totally separate network in order to connect to the Internet in one and directly to other devices in another. We are talking, for example, of a NAS (Network Attached Storage). Obviously, a normal person will have enough to take advantage of their existing local network, since it will surely have performances quite similar to those that the NAS itself can give.

For example, using a normal Gigabit connection, assuming all the bandwidth is available on the local network, we would have 1000 gigabits / s at our disposal, which is 125MB / s. This transfer rate is similar to what a normal HDD can give.

However, there are cases where this is not enough. A very high-quality content creator who needs a NAS or auxiliary server for mass storage will greatly benefit from dedicating an entire network to it or directly connecting a dedicated LAN to the NAS, without losing internet access. This becomes even more beneficial if we consider that one of those additional LANs could even reach 10 gigabits of ethernet, allowing extreme applications.

Link aggregation to get performance on the same network

Another extremely interesting possibility will be to forget about using different networks, but to use two different links to the same network and combine them into one. This is what is known as link aggregation, and in theory it offers some interesting advantages, allowing more bandwidth and a load balancing of the connections that should mean an interesting performance improvement.

However, in practice, not everything is perfect. Let’s start from the idea that not all routers support link aggregation, in fact most do not, in addition to that it cannot be said with certainty that the performance with the NAS will improve, and we also have to do that aggregation with the own NAS. Perhaps the previous idea will be more profitable.

We can also benefit from the load balancing or load balancing, on the motherboard distribute the load between these two links in the most efficient way possible, and balance the bandwidth used by each link.

Redundancy so you don’t depend on a single cable

In addition to link aggregation, this use of 2 LANs to connect to the same network can have redundancy benefits if one of the cables fails. Needless to say, this is highly unlikely in the home environment, but in many more professional applications such a possibility could be appreciated.

Not depending on a manufacturer’s drivers

This is an increasingly less interesting advantage, since most operating systems support almost any Ethernet NIC on the market without problems . But there may be a specific case in which having two different LANs saves us from possible driver problems with one of them. Actually, it is somewhat unlikely even on Hackintosh machines, where more and more Ethernet cards are supported.

What can be considered a more common advantage is avoiding performance problems that may be caused by a specific NIC. In network cards there are quality differences that for some demanding users can be made noticeable, or you can even benchmark both connections to see if there are substantial differences in speeds and latencies.

Examples of boards with dual LAN

Now we go with some real examples of current motherboards that incorporate two LAN ports, focusing on the domestic range of processors AMD Ryzen 5000 and Intel Core 11th generation. In all cases we will be looking at motherboards of a fairly high level, which are the ones that usually incorporate it, but obviously there can always be an exception if the motherboard is intended for a specific purpose.

Examples of Dual LAN on AMD AM4

The Asus Crosshair VIII Formula and its combination of 1 Gigabit Intel and 5 Gigabits Aquantia, or the Hero with 1 Gigabit Intel and 2.5 from Realtek. We also find B550 boards with this feature, such as the Gigabyte B550 Vision D and its dual 1 Gigabit Intel Ethernet.

11th Gen Intel Core Dual LAN

The ASUS ROG Maximus XIII Hero includes two 2.5GbE ports , each with an Intel I225-V controller. We can raise the bar with the Gigabyte Aorus Z590 Xtreme, as one of the ports also uses the same controller, but another includes a 10GbE Aquantia, an extremely interesting figure for a high-performance local network (the same is included in the equivalent AMD AM4).

QLED vs OLED : Which TV You should Buy in 2021?

0

When we want to buy a television we have the doubt about which panel we should buy. Therefore, we bring you the comparison between QLED vs OLED in order to help you choose between the best panels on the market.

LG brought the OLED , while Samsung tried to answer it with the QLED , but there are big differences between one technology and another. From the outset, the name may confuse the consumer believing that it is the same technology, but the truth is that they have nothing to do with it. We will briefly explain what each panel is and then we will compare them to dispel your doubts.

OLED

This panel is used mainly by LG , although it is a technology that the Korean brand shares with other brands such as Sony, Panasonic or Philips. We really have to go back to 2004 to see the first OLED TV, which was introduced by Sony .

It was still a technology that was “green”, but the consolidation comes from the hand of LG in 2010 with the 15EL9500 OLED , a 15-inch TV. However, it was still early and we can talk about the OLED panel seriously from 2013 , although they came to the market with the famous problems of ” burn-in ” or burned .

The acronym stands for Organic Light-Emitting Diode and it is an organic panel that works without a backlight . This system allows each pixel to be illuminated individually, thanks to which the famous pure blacks are achieved.

The lack of backlight is a crossroads: the panel sacrifices itself in brightness , but in dark scenes the image is brutal. It must be said that the result is more than satisfactory because, in this way, a dark scene is much more realistic . On the other hand, we can find LED panels that are brighter than OLEDs, but is it worth it? Later, we will see that brightness and ” nits ” are not everything.

In addition, the OLED panel is composed of carbon (hence it is said to be organic), as well as fewer layers than a conventional LCD-LED panel. This translates into a much lighter weight and a smaller thickness on the TV. This feature may not be as interesting to the user as it will not move the TV around the site.

However, this panel has really good benefits and we should talk about:

0.001 ms response time . As far as televisions are concerned, it is a great advance because LED panels usually come with about 8 ms easily.
Improved refresh rate . To say that this feature depends on the TV, but we will rarely see an LED LCD with 144 Hz refresh rate. In OLED, LG has some option with this feature.
Very good color space . In OLEDs we will see very vivid colors thanks to the fact that the panel contemplates a very wide range of colors.

QLED

In this case, we find a technology completely unique to Samsung , although we can see some brands use panels such as TCL . It appears as the alternative to OLED, but will it really be?

The Korean brand explains that the QLED panel is based on Quantum Dots , ultra-thin semiconductors measured in nanometers. All Quantum Dots produce different colors of light (depending on the size of each one), allowing a precise light emission, since they adjust to speeds of quantum level.

Samsung sells us the QLEDs as a ” high brightness ” panel , referring to the brightness of the screen. Hence we see the word ” nits ” everywhere in the advertising of these televisions, an aspect in which they win by a landslide. And is that a high brightness benefits the contrast ratio , as well as the capabilities of HDR (high dynamic range).

Samsung QLED backlight

What about the blacks? Samsung implements Direct Full Array , a backlighting system , and here we are going to expand further. Unlike OLEDs, the QLED is an LED panel that needs backlighting despite the similarity of its name, but we found 3 main systems:

It is the cheapest system and is characterized by putting LED strips at the ends of the panel, being able to find a strip or 2 strips. The disadvantage of this panel is when there is a scene that requires lighting only in the center. Since the LED strips are at the ends, they must go the extra mile to make the center light up, causing unrealistic lighting. In these panels there are no blacks , but grays.
Direct LED . In this case, the LEDs are at the rear and come without Local Dimming (technology that dims areas where light is not required and enhances areas that require brightness). It’s another cheap backlight system, and its contrast is usually low.
Full Array Local Dimming ( FALD ). This system is present in the high-end range and is characterized by having LED diodes throughout the panel , which leads to higher consumption. Removing that, the illumination of the entire panel is much more accurate, allowing more realistic blacks because specific areas can be turned off. It is the best system of the 3, but also the most expensive.

In the case of the QLED , they sell us the Direct Full Array as a solution for pure blacks, but the truth is that it is another backlighting system. The problem here is that we must investigate well the QLED panel we are interested in, since it can be Edge LED or FALD.

Hybrid cloud emerges as one of the main IT trends in 2021

Social isolation, the growth of the home office and the increase in the consumption of digital services meant that companies needed to adapt and rethink processes. Technology appeared as an ally: it helped to automate activities, made it possible to innovate, and became the main priority of companies, as shown by a survey by Red Hat, the world leader in open source solutions. “The pandemic has driven digital transformation like never before, and now reflects directly on companies’ priorities for computing in 2021,” says Paulo Bonucci, vice president and general manager of Red Hat for Latin America. In the following interview, the executive talks about technology trends for 2021.

Was Covid-19 largely responsible for the technological repositioning of companies?

If, on the one hand, the pandemic was an obstacle that companies had to overcome with changes and protocols, on the other hand it acted as an accelerator. It was a turning point that made it possible to see aspects that companies needed to prioritize in order to continue growing in line with the demands of the current world. Covid-19 has driven digital transformation like never before and now reflects directly on companies’ priorities for computing in 2021. The cloud appears as one of the top business priorities for this year.

How is the cloud adoption in Latin America?

Developing countries are accelerating the adoption of the cloud. In Latin America, in particular,
there is no shortage of initiatives, but platforms need investments to gain scale, something that should
happen in 2021. According to the Red Hat study, the region, alongside Asia-Pacific, is where we will see more changes and advances. Companies plan, at a minimum, to triple the use of clouds, tracing the paths for the migration of their systems.

Why, within this strategy, is the hybrid cloud the best option?

The demands of customers and IT staff are increasing dramatically. To meet them, it is necessary to have applications and infrastructure available and reliable in all environments. The hybrid cloud offers flexibility, mobility, cost reduction, efficiency and security, uniting the best of the private and public cloud. Using exclusive servers, it guarantees protection of data storage, while providing shared allocation services, at a more accessible cost, for the exchange of less sensitive files.

Does joining the cloud put companies on another level in relation to digital transformation?

Analysis of the data collected by Red Hat’s research shows that the digital transformation is ongoing. Moving forward is not a choice, it is a mandatory option. Many companies believe they have reached their maturity, while others are still taking their first steps, but all can count on solutions capable of meeting the main market demands. The digital transformation remains an important tool for companies to overcome their immediate challenges, while building new instances of growth.

What is the role of open source in this regard?

Open source appears as a major highlight in this journey, offering scalability, flexibility, collaboration and transparency at a time when companies need it most. Open source technology makes it possible to unlock the potential for business innovation and modernization more quickly, making it possible to keep up with the fast and constant market changes.

Intel CEO Pat Gelsinger spoke out today about Intel’s future plans, the main content will be: Investing in companies across the United States and Europe and opening a new manufacturing facility in Arizona with a budget of US $ 20 billion. And most importantly It is to talk about the 7nm “Meteor Lake” CPU production plan that we should be able to see in person by 2023.

Of course, the most interesting content at today’s event is probably the most anticipated Intel 7nm. After allowing AMD to take a lot of market share. And still can’t go beyond 10nm

The 7nm ‘Meteor Lake’ is a follow-up to Intel Alder Lake, a likely Intel 12th Core I Gen that will be available at the end of 2021 and likely to be available at the end of the year. Until 2022, before launching Intel’s first 7nm CPU Meteor Lake by 2022 and ready for sale by 2023.

So what can we expect from Intel’s first 7nm CPU ??

Actually, we cannot tell anything about this matter. The only information we know is that Intel will be partnering with TSCM to produce Meteor Lake, and Intel also stressed that their CPU will provide a tight transistor and it will outperform existing 7nm CPUs. Of course now.

Let’s take a look back at Alder Lake, a desktop CPU likely to be released later this year, a 10nm CPU using Intel SuperFin technology to produce a 10nm CPU, which we’ve already seen in the Gen 11 Tiger Lake. That is in the Laptop, or simply Alder Lake, is Intel’s first 10nm Desktop CPU so it will be easier to understand.

Alder Lake will come with a lot of new capabilities in the new chipset and Socket LGA 1700 along with support for DDR5 RAM and PCIE 5.0. Gen 11 of the desktop PC market (Laptop market is already 10nm area)

So what we can expect from 7nm should be the development of a CPU transistor that transmits information quickly. Intel’s manufacturing technology and functionality are significantly better than those of AMD’s.

Of course, we still can’t decide anything. But this is another good news for Intel fans who have been waiting for the Intel 7nm CPU for a long time.

Google has released an update to Android 12 Developer Preview or a new test version. But since it’s a test version, Google hasn’t released all of the new features. But the developers have already found some new faces out.

XDA-Developers New UI changes have been published in the Notification and Lock Screen sections, with Notification’s background using a more opaque color scheme compared to the current version. There is an icon indicating that the microphone and camera are in use. Including switching the position of the date and time as well.

Android 12 has improved the display of Always On Display, Lock Screen, Notification, the design of the watch has been slightly changed. The hour’s time is above the minute, and the At A Glance widget is in the upper-left side of the display. Under the widget you can find a notification icon on the Always On Display screen.

However, this new design does not appear in Android 12 Developer Preview, developers have to dig and find each other. Which is likely to have a lot of things that Google has hidden in this version of Android 12 Developer Preview and there will be a lot for us to see.
