I did a test on my S21 ultra 5G Exynos 2100 everything is stable I did a 5 hour test I think Samsung could extend the update time of the S21 series up to One UI 8 because it supports One UI 7 very well
#S21
(BUG) But I find that the Always on display has an energy problem instead of 60hz it is at 120hz which consumes a lot of battery in 7 hours your battery can end for no reason because of AOD ! And slowdowns when we search for emojis.
