This feature worked in my app for a while, but I recently rolled out a new update for my android app and for some reason it's causing colour issues and other glitches. Also apparently there are other glitches happening too, I haven't changed any of the code. The colour issues only seem to happen when you save pictures. Not sure about the weird stretching.
Here are some screenshots users have sent me. The skin colours are not meant to be blue and all the other colours are messed up as well, like there's a weird filter over the image, and the body has become all stretched.
