When I played game on device, it's so imporant mistake during playing.
I can not see sentences when Harry and other friends says together.
During loadring it's empty photo and anything. My device is Galaxy Mini 2.
CPU- Armv7 Neo. RAM : 512 RAM. Anyone knews how to fix it?

My device have Android 2.3.7. Drastic is running on the device not faster. He sometimes have lags and freeze, when I'm played the game. Absoluteloy I'm shock. Where's the problem?

My device have got a parameters :
