Certain quality of life improvements required which are old features on other android but oneui needs it.
1) App lock - Secure folder is not always convenient we need individual app lock a standard oneUI feature
2)Battery health and replacement warning for a weak battery - Internal are something which cannot be understood by a normal user but if there is an battery health indicator it will help users replace the battery at right time to avoid battery related hardware damage.
3)And using the display camera cutout for dynamic functions like the dynamic island the android way. (LET THIS BE A GOOD LOCK MODULE)
This is something on top of my head will addon if more required but these are 100% needed.
