As the phone gets it's last os yesterday, i noticed that they downgraded it's actual functionalities.
1. AOD Brightness and customization is removed.
2. AOD is not even visible in low light conditions and fonts are also so small that you have to watch it so attentively, previous font size and customization of colors was a good thing.
3. Protect battery for maximize is also reduced 5%, previous 85% setting was good.
4. Notification category also removed, now it's so confusing to understand and block to unnecessary section in the Notification
5. Phone is now heating while charging.. it was not there in 6.0 update
6. Gallery also removed swipe up photo to erase object and reflection setting, which was very convenient to use.
This are some problems I have noticed in just one day. One UI 6.1 is not update but downgrade in terms of functionality and user experience.
