Suggestion : Put 60hz instead of 120hz on the notification panel and put 96hz when they have increased the volume instead of 120hz let's switch to Dark Mode let's put the applications in black for the dark mode and the battery icon a little more gray instead of full white and put a good optimization for the LTPO screen | now let's talk about the Galaxy S21 Ultra you put 120hz for nothing on the always on Display I strongly suggest 60hz and improve the fluidity for the Galaxy S21 and put One UI 8 for all S21 not only S21FE would be unfair even if we know that the S21FE came out 1 year later it's very unfair thanks goodbye.
Wiping the phones partition worked for me,and use low power mode switch of Bluetooth and wifi location services. If possible switch off Location services completely,but the downside is when they steal your phone,you can't locate it
