Last weekend, users found that a regular picture can turn Android smartphones into a "brick" if you set it as wallpaper. The publication drew attention to the problem 9to5google. Journalists say that the famous Ice Universe insider was the first to report a strange bug.
Never set this picture as wallpaper, especially for Samsung mobile phone users!
It will cause your phone to crash!
Don't try it!

On his Twitter account, he said that a regular picture with a landscape, if set as a wallpaper, could cause some smartphones (especially Samsung) to malfunction, essentially turning them into a “brick”. In fact, after setting the wallpaper, the device stops responding, constantly turns the lock screen on and off and does not allow you to do anything else. Fortunately, these damages are reversible, that is, the device can be brought back to life using relatively simple methods, such as deleting a file in safe mode or completely resetting through the bootloader.
It is highly recommended not to conduct tests on their devices, even if it is not Samsung. So, the video below clearly demonstrates what happened to the Pixel 2 smartphone, owned by 9to5google, after installing these wallpapers.
Users and journalists experienced a dangerous picture on other devices and received the following results: Huawei Mate 20 Pro, OnePlus, Pixel 4 XL devices running Android 11, as well as a number of other brands of devices, continued to work normally, while the Pixel 3 XL on Android 10 ceased to function.
At first, theories said that a problem could arise from corrupted image metadata, but it turned out that this was not the case at all. Shortly after the first Ice Universe tweet reportedthat after uploading to Weibo, the colors in the picture changed a little, and it became harmless.
Eventually it became clearthat the bug is due to the color space of this particular image. The fact is that Android usually works with sRGB, while the dangerous landscape uses RGB. And if in the case of Android 11 the system is able to convert the color space (in the case if there is no support), then the version of Android 10 is not capable of it. That is, in fact, the problem is not only affecting this image, but similar failures can occur when using other RGB images.
Journalists have already contacted Google representatives to find out why this error occurs and whether to expect any corrections, but so far the company representatives have not responded to the request.
