I bought this app with the hope of being able to turn photos in to pixelated images for my wallpaper (Live Pixels) Deva seem to not want to answer anyone's question and they haven't updated it in 2 years. I use a Samsung galaxy s7 and the way the photos are accessed is through the devices internal storage , it automatically leads me to the right folder (DCIM) but nothing is in any of the folders, it says to use small pictures so I tried a 200x200 but it still won't work I used PNG and jpeg is there a specific file I'm missing?
