Hello,
Sorry to hear you are still having issues. I think this issue may be local to your device as I have not gotten many other reports on it.
Id love to fix it, but am pretty limited in my ability to do so. For Android, I just use the built-in distribution tool renpy includes. So basically I only build for PC and trust the renpy tool to do the rest. So when there is a mobile specific issues it challenging for me to fix. Very sorry :(
