(From this OnePlus 3/3T thread on 4PDA, via Google Translate.)
Android 10+. GCam 7.2.011.
The first version. Added some basic functions, corrected something, drew, for the most part I wanted to get a normal picture by correcting the front (the custom front TN), but on 7.2 it all works a little strange, although it seems to have worked out fine, so far.
