Notes:
- flickering is caused by dynamic refresh rate (gamma shift) - if u find it alarming, use static refresh rate or lock refresh to 60hz or 120hz instead of 60-120hz(auto)
- if experiencing slow charging, try replacing kernel.
- if experiencing battery drain, try replacing stock with custom kernel.
- if usb options doesnt show up on first plug, replug it again.
- for fastboot use fastboot enhanced or any fastboot tools from official community group or verified xda forum.
