About the kernel and if it is for gaming, this kernel is mainly very close to stock and not heavily modded. So if you didn't had any issues with stock kernel this one will be good for you as well!
As said waiting for AQGB kernel source code!
That only happens if you are NOT on AQG5, reason: camera libs need to be updated otherwise the camera will constantly loop your device (some seconds after successfully boot process)
i dont think thats possible because i flashed entire aqg5 firmware through odin and on omega 4.0 which is a aqg5 rom, no problems using noto kernel which is also aqg5, also wondering if the little core max cpu issue has been fixed on the latest beta
