News from the camp of displays, chip for protecting confidential information, test for survivability of Galaxy S20 +


Korean Samsung amazes with its fertility and efficiency. In less than two months of 2020, she has already announced two lines of smartphones, several single models, among which there was a place for a device with a bendable display. What can I say about other gadgets and products. It is clear that the company is not going to stop there. Recently, it was reported that the company's engineers have developed a new generation of OLED displays that are energy efficient. Also, work on the creation of a new chip for data protection ended with success. Let's talk about these events in more detail. We'll also discuss the results of the vitality test of the recently announced Samsung Galaxy S20 +, along with information about its internal structure.

Samsung smartphones are coming soon with better displays

The Korean manufacturer has announced the successful completion of work on updating displays for mobile devices. They differ from their predecessors by a higher level of energy efficiency and emit fewer rays in the blue spectrum.

Samsung claims the new OLED displays are capable of emitting just 6.5% blue. The matrices that are used now give out almost 14%. This is a relevant improvement, as recent studies have shown that it is blue that can cause circadian rhythm disturbances in humans. This is fraught with insomnia and other sleep disorders if you use your smartphone at night.

It was also announced a 15% reduction in energy consumption compared to current counterparts. This optimization is recognized as timely, as the era of 5G networks is coming, which allows consumers to consume more video content. Such processes lead to faster battery discharge.

The manufacturer hopes that the new screens will help maintain the same battery life despite the increased screen time.

Data protection chip

Mobile devices are constantly being improved and re-equipped. The requirements for them are growing day by day. Many models are already equipped with hardware encryption to protect personal data and other information.

Samsung recently developed the S3K250AF chip and optimized software to protect confidential information in isolated storage.

A tech giant from South Korea presented a turnkey solution - Secure Element for mobile devices (the common name of the chip and software). It is certified to the Common Criteria Evaluation Assurance Level 5+.

S3K250AF is able to securely store passwords, fingerprints, PIN codes and many other data. They are written into the SE memory, which is not accessible even by the smartphone OS. Therefore, fraudsters, even by infecting the device's system with a malicious application, will not be able to gain access to the above data.

The chip is able to communicate directly with payment terminals, it is not afraid of laser attacks, reverse engineering and various failures.

Samsung said the Secure Element is already in use in the Galaxy S20 lineup. This equipment is already mass-produced, which makes it possible to use it in their products by other manufacturers.

iFixit showed the location of parts inside the Galaxy S20 Ultra

The iFixit laboratory is renowned for its technical capabilities. It is customary there, before starting the repair of the device, to study it carefully.

Recently, a video from iFixit appeared on the network, which talks about the internal arrangement of the Samsung Galaxy S20 Ultra.


Below the Quad HD + display, there is a high capacity battery and cooling system. On the side edges of the device are antennas that receive 5G signals.

One of the main elements of a smartphone's technical equipment is the motherboard. The processor, the main camera unit is mounted on it. It is removable and has four sensors.

The video demonstrates the good maintainability of the device. All its elements and loops are made of high quality, easily disconnected, dismantled. There is no glue on the inside of the device, which indicates a high quality of assembly work.

Check for survivability

Samsung Galaxy S20 Ultra was previously tested for battery autonomy. The other day, the researchers decided to test its younger version - Galaxy S20 + (with a 120 Hz display and a 4500 mAh battery) for survivability. In addition to this device, the test was attended by Apple iPhone 11 Pro Max, OnePlus 7 Pro, OnePlus 7T and Samsung Galaxy Note 10.


The devices are fully charged, the brightness of the screens is set to 50% of the maximum values.

They were first tested with a two-hour session of PUBG Mobile. After that, the S20 Ultra has 61% charge left. Compared to other models, Apple retained 77%, OnePlus 7T and 7 Pro - 68 and 66%. The Galaxy Note 10's battery was roughly similar to its brand sibling.

After that, smartphones were forced to play YouTube videos for 2 hours and 20 minutes. Here the picture was about the same.

In the end, the devices were loaded with video shooting and work in social networks. Galaxy S20 Ultra turned off after 6 hours 15 minutes, Note 10 lasted a little longer - 6 hours 41 minutes. Other smartphones showed great autonomy, but the iPhone 11 Pro Max withstood the longest - 8 hours 25 minutes.

The results of the Korean novelty were considered good, since during the tests the refresh rate of its screen remained at a constantly high level - 120 Hz.
