Hi - had this problem for weeks.
Droid1. Using GameGripper. Go into Men/Settings/Input/Hardware Keys. Set up directions, 4-button pad, L1, L2, R1, R2. All works. Go to System, try 'Default config save'. Try QUIT/RESTART, everything.
BUT EVERY TIME I START FPSECE I HAVE TO REPROGRAM THE Hardware Keys. Driving me crazy.
Went through the documentation, etc. etc. (is that written for Android?).
Please let me know what I am doing wrong.
