The rom is quite stable in terms of battery and performance but there are many flaws in UI which I am mentioning below:-
1. Status bar icons are near the bottom of status bar in landscape mode (screenshot attached).
2. Fingerprint sensor indicator is displayed at wrong position (screenshot attached).
3. Corner of app windows in recents are sharp instead of round (screenshot attached).
4. Phone services use location all the time
even when GPS is off (screenshot attached).
5. Animation when we unlock phone with fingerprint in screen off is laggy.
6. Sometimes media player is not visible in notification panel.
7. Overall volume of phone is lower.
8. App lock is missing.
And it will be very very nice if you provide the next update with a good camera app with support for all the 6 lenses present in the phone. Stock realme camera app is also a good option if you can port it.
