Should the new year be like the current one, Samsung should present the Galaxy S23 in February. Several rumors about the features of the new smartphone series have surfaced over the last few days, affecting areas such as the processor, display, camera and connectivity. ComputerBase summarizes the latest messages.

Snapdragon 8 Gen 2 with higher clock rates

It has been speculated for a long time that Samsung will no longer install its own Exynos processors in Europe in the coming year, but will switch exclusively to Qualcomm. Qualcomm itself has confirmed, based on statements by CEO Cristiano Amon, that it will be globally responsible for the supply of processors next year. This means that the use of the new Snapdragon 8 Gen 2, for which the editors have already been able to carry out their own benchmarks on a reference device from Qualcomm, is as good as certain. Meanwhile, the cooperation with AMD for new mobile GPUs with RDNA is to be continued at Samsung's chip division.

However, as Ice Universe reported on Twitter, it should not remain with the use of the standard model from Qualcomm. According to SamMobile, the faster variant SM8550-AC is planned specifically for Samsung instead of the SM8550-AB model, which has a higher clock for the prime core based on the Cortex -X3 and a faster GPU is said. The CPU's peak clock is said to climb from just under 3.2 GHz to 3.36 GHz, while the GPU is said to go from 680 MHz to 719 MHz.

ComputerBase spoke to Qualcomm about the subject at the Snapdragon Tech Summit, where the manufacturer denied higher clock rates for the chip because you set the maximum yourself. Strictly speaking, the SM8550-AC would no longer be the exact same processor, so higher clock rates cannot be ruled out. Since Samsung will probably be by far the largest buyer of the Snapdragon 8 Gen 2, a special configuration for the best customer is quite conceivable.

The Snapdragon 8 Gen 2 is accompanied by the change from LPDDR5-6400 to LPDDR5X-8400, and memory of the UFS 4.0 standard is to move into the smartphone, for which Samsung started mass production this August. UFS 4.0 was also recently found in the Vivo X90 Pro+, which was only recently introduced for China.

OLED display with over 2,000 cd/m²

When it comes to the smartphone screen, Samsung will most likely use Samsung Display from its own warehouse. A new OLED panel with a maximum brightness of probably 2,150 cd/m² will be used especially for the Galaxy S23 Ultra, reports RGcloudS, after the maximum was previously 1,750 cd/m². In the test of the Galaxy S22+ and Galaxy S22 Ultra, almost 1,900 cd/m² was even possible with a small amount of white. Apple recently broke the 2,000 cd/m² mark in the iPhone 14 Pro Max (test) using an OLED display from Samsung.

Also associated with the screen is an even stronger glass that is said to offer better protection than Gorilla Glass Victus+. According to RGcloudS, the gap to Apple's Ceramic Shield should be closed. A larger fingerprint sensor is also to be integrated into the display, which should again come from Qualcomm. According to Ice Universe, the new ultrasonic fingerprint sensor should be larger, but not significantly larger, so that the use of the 600 mm² 3D Sonic Max, which has already been circulating through the rumor mill, is doubtful. Instead, there should be a new version of the 3D Sonic Sensor Gen 2, which so far has measured 64 mm².

Camera with 200 MP resolution

In the camera area, the in-house, not yet announced ISOCELL HP2 with a resolution of 200 MP should be used as the primary sensor. The Galaxy S22 Ultra uses the ISOCELL HM3 with a resolution of 108 MP. At the Snapdragon Tech Summit, Samsung was named alongside Sony as one of the partners who will offer image sensors specially tailored to the Snapdragon 8 Gen 2. So far, there is no ISOCELL HP2 in Samsung's portfolio, instead the ISOCELL HP1 and the ISOCELL HP3 presented this summer are the latest additions with 200 MP. With a pixel size of 0.60 μm, the ISOCELL HP2 especially for the Galaxy S23 Ultra should be placed between the HP1 (0.64 μm) and the HP3 (0.56 μm).

Satellite communication with Iridium

The connectivity of the Galaxy S23 series is to be expanded to include satellite communication, reports ET News from Korea. The English-language version of the article states that the satellite communication system from the provider Iridium, consisting of 66 active satellites in six orbits, is to be used for this purpose. Samsung is said to have been working on the implementation for over two years in order to master the technical challenges, especially in the area of ​​antennas. There is significantly less space for this in a smartphone than in classic satellite phones, which are often clumsy. It should be possible to send text messages and images in low resolution via the satellites.

There is currently a trend towards satellite communication in smartphones, which is mainly due to support from Apple in the iPhone -14 series has received a significant boost. Apple relies on Globalstar's satellites and also operates relay stations on the ground. With Apple, the emergency feature can only be used if no connections via the mobile network or WLAN are possible. The “Emergency SOS via satellite” feature has recently become available in North America and is to be expanded to include the German market in December. Huawei offers a similar feature only in China for the Mate 50 Pro.
