Also can not save Game Settings on some Devices or for some Games. For example: 
fghthist (Fighter's History (World ver 43-07)). I change options in the Service 
Mode (Free Play and change the Difficulty). Or I change umk3 Settings in the 
Service Mode like Difficulty, increase the Volume to Max, and Free Play. When I 
exit the App, and start it again, everything is Default and I have to change 
everything again.
Happens on Note Pro 12.2 and NVIDIA Shield Portable (Android 4.4.2 for both)
