  As many people reported that their android device is stopped working after use this image as wallpaper. after search about it and I got some awesome information about the android device. let's start. right now android supports 1440 X 2560 screen resolution. when see the original photo i saw its a ProPhoto RGB is this the  problem ?  Let's find out this is the colors scale that human see android device under stands sRGB color scale. like this, not only android there are tons of hardware supports this range of colors. there are another color scale we have like adobe RGB as you see here it covers larger color then sRGB. and now comes pro photoRGB so prophoto rgb is the problem lets see google use convert prophoto RGB or adobe RGB to srgb by luminance effect so the luminance of pixel is calculated by this formula 0.2126 X (RED)+0.7152 X (GREEN)+0.0722 X (BLUE) =255(MAX) in case of pro photo rgb lets see a pixel calculation. 0.2126 X (255)+0.7152 X (255)+0.0722 X (243) 54.213+182.
