This is a tutorial for the best configurations to get the best from the GSI roms on the Xiaomi 11T Pro

If you are searching on a tutorial on how to install GSI roms on Xiaomi 11T Pro you can check this post

The reason why I made this guide is that there is no custom rom currently for Xiaomi 11T Pro and the only way to get custom roms is by installing a GSI rom and try to tweak with it to get it working.

You can now fix always on display and set the statusbar height to a value that covers the hole punch by flashing this magisk module by diogotc.

Know Issues​

Currently the issue that I am still experiencing with GSI roms are:

1. GCam can record up to 1080p 60fps. 4K is not working.

2. The proximity sensor is not working always especially in AOD, So I recommend to disable DT2W (A- Phh Settings step 3).
