It seems that using this picture as a wallpaper can cause certain Android phones to fall into a bootloop that can only be broken by either restarting your device in safe mode and deleting the offending wallpaper before restarting normally or manually deleting wallpaper data using a file browser.

In particularly bad cases, users have had to resort to using their device's recovery mode to get things up and running again, and not every user has been successful at recovering their device.

As such, do not attempt to download and apply this wallpaper to your device (or anyone else's).

Out of range

So why does a seemingly innocuous wallpaper of some mountains send so many devices into a panic? It has to do with the gamut and dynamic range of the image's makeup.

According to developer Davide Bianco, the image adheres to the RGB colour space, instead of Android's native sRGB colour space and the fact that some of the image's values exceed the range of sRGB is enough to cause the SystemUI component of Android to crash.

Further testing from multiple sources, including a report from 9to5Google, reveal that only devices running Android 10 or older (which is admittedly most Android devices currently on the market) are affected.

Based on the Android 11 Developer Preview, the system automatically converts images that use an unsupported colour space, negating the risk entirely.

Presently all-manner of Android phones are at risk from the effects of this wallpaper, with Samsung Galaxy phones and Google Pixel devices apparently being the hardest hit.

Fixes are inbound

Bianco has already proposed a fix for Android by suggesting to limit the y-value ('y' denotes a colour's intensity or brightness) of images to 255. He has also submitted a fix of his own to the AOSP (Android Open Source Project) repository.

Samsung is also apparently aware of the bug and according to SamMobile is said to be including the fix in forthcoming Samsung Galaxy software updates.
