Since first 1.8.x update i have weird issue - white screen on launch. Before this update everything were fine.
I can hear clicking sound if i press touchscreen where menu options are supposed to be, so the game itself boots up and working, just a white screen instead of a proper image.
Cleared cache, reinstalled app, reinstalled OS - nothing helped. Official Android version were 4.2.1, now i installed custom ROM (Android 6.0.1) and it improved overall tablet perfomance and compatibility with other games (in some apps it works a lot better, than original OS). But Minecraft still doesn't working.
