Never set this picture as wallpaper!!

 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+182.376+17.5446

=254

let see google round the value which previously get like.

54.213+182.376+17.5446

we got : 55+183+18 =256

which is grater then 255 value

BOOM!! "ERROR"

one number in one pixel is destroy your device and hold it in a loop.

you can use this image in android but as a wall paper it may be destroy your host OS.

now , what is the solution till new android update.

its simple just use image by taking screen shots from android.


Thanks
