Just trying to find out some stuff before flashing:
1. There is no stock camera app, but can you record 4K somehow? Gcam usually just allows 1080p.
2. Some say the audio in video recording is mono?
3. Are Gcam version 6.X stable on this ROM?
Where did you get it?
You don't have any problems at all?
got it from AliExpress . everything works well
Nope you are not alone. I faced the same issue after updating to v7.
Disabled all the substratum themes from twrp and then boot into system. It will solve your problem.
Thanks dude:good: u r my saver
