Hi, I installed RetroArch on my Wiko Cink Peax 2 (Android 4.1.2) and I have a problem wich concern every Core, Content (rom) and touchscreen overlay :
As I touch one button on the touchscreen this one is ‘activate’ and he will stay in this state until I touch another one.
For exemple, if I launch Pokemon with the GBC Core Gambatte and I push the A button in the starting menu, it will open the selected entry. But then, I have to push another button (ex: left arrow) to ‘desactivate’ A and be able to press A again to open the new selected entry.
Another exemple, once in game, if i push the left arrow, my character will continuously go left, straight into the wall (except if i push another button 
I made tests with several games, cores and touchscreen overlays and the problem is always the same.
Thanks in advance for any advice.
