Samsung and Google working on fix for wallpaper bug in Android

Samsung and Google are both working on a fix for the bug that causes reboots when users set a certain wallpaper. According to Google, the flaw lies with the way Android calculates the brightness of grayscale.

Samsung will soon come up with a fix, says SamMobile. Google will also come up with a fix, according to commits. Phones crashing and rebooting using specific wallpapers is due to the way Android calculates grayscale brightness, says Romain Guy from Twitter.

Due to a rounding error, the value exceeds the maximum, causing SystemUI to crash because the software cannot handle it. The error continues to occur because it is in the wallpaper and is displayed every time users start up the phone. Factory reset is recovery mode is a solution, but users will lose all their data. Trying to change the wallpaper quickly is another option.

The problem occurs up to Android 10, but is not in Android 11. Samsung phones seem to be more affected than users of other skins, such as those from Huawei and Xiaomi. The bug surfaced last weekend.
