Samsung Galaxy S20 Ultra – screen and cooling problems

Samsung Galaxy S20 Ultra (review HERE) is not a very beloved phone. Although it is very well equipped, the very high price does not make it very attractive. More recently we find that it has serious problems reported by users.

We are just talking about the Exynos chipset variant, the most controversial platform.

Samsung fans are unhappy with the performance of this platform compared to Snapdragon, and some even made a petition to quit Exynos.

After problems with the overheating that remained unresolved, the S20 Ultra also has problems with the screen. Apparently the problem appears only on variants with the Exynos platform.

As you can see in the picture, the OLED screen turns green when the background is black.

According to the users the problem appeared immediately after the last security update, so it may be just a software problem. Samsung recommends resetting the phone to factory settings, which is not a pleasant action.
