How to set a lossless quality wallpaper? I'm trying to set a .png file I had prepared myself as the wallpaper, but the thing apparently (as in EVIDENTLY) gets converted to a .jpg.

It strikes me odd google.com has nothing on this issue, that's why I've come here.

Is there a way to set a .png wallpaper without it being converted to .jpg? A workaround app maybe?



This is a png screenshot, scaled x2. Note the artifacts by the edge of the shape.

EDIT: 6 JUNE 2015
Conclusions from my investigation (and answers below) so far:


Android stores the wallpaper file in a png
This means the fault lies within the piece of code doing the cropping and saving the new file
In my context (samsung a3 original firmware) I have yet to find a resolution which would bypass the cropping tool, allowing me to set the file as is


THERE ARE MEANS of achieving the effect though:


Muzei app is quite easy to set up, streaming whatever source you like to your wallpaper (including unconverted image files -- or a single file)
Surprisingly, Moonshine's wallpaper setter does its job the right way too, although it only handles the few graphics that are bundled with it (however lovely they are).
If you're looking for a workaround, you could try Muzei: it is a live wallpaper, which you can set your own wallpaper to.
