Rg556: Android apps crashing, screen rotation issue, battery.

[Gabbiruu18]

I recently switch my rg556 os from stock into gamma os next full.

It's great but there are some bugs that I've encountered, like Bluetooth turns off and on, sometimes its the wifi, then the Android apps keep crashing like tiktok, facebook, messenger etc, it only last for a minute when i open it, it crashes too when i rotate the screen, and there is the fast switching of emulator without clicking any buttons, it always occur when i open the device, then there's the screen rotation it's doesn't detect the native screen position of the app, like when i open chrome and the auto screen rotation (all of the screen position is on from 0 to 360), when i hold it on a landscape position the screen rotates into portrait but when i hold it in a portrait position it now turns into a landscape but in the other way screen is now upside down landscape when i hold it in portrait, and the battery, the os says that my battery isonly 5000mah but the deive is 5500mah, and do you guys use a fast charging charger? Cuz apparently after switching to gamma os my 556 is now supporting rapid charging.

Sorry for the long and confusing explanation, but i hope you guys can help me if there's a solution.
