I have the base S21 and have not noticed any stuttering since the update. However, the phone is consistently warm when idling and the battery life has now taken a hit and it was brilliant before. I've even cleared the cache partition and it didn't seem to help with the heat... (btw to do this you now need to have the phone plugged into a laptop when off and press and hold the volume up and power button and let go when the samsung logo shows)
1.Firstly, swipe down to open Upper Bar and tap on the Power icon. 2.Then hold down Volume Up and Power button until you see SAMSUNG Galaxy logo on the screen. 3.Now go to Wipe cache partition. ... In the next step select Yes option by using the same keys as before. 4.At last, choose Reboot system now with the Power key.
Yes. I suspect that Samsung have altered the "touch boost" on the kernel to save battery and heat. This would have the effect of causing slight stutter on scroll and in general. this is what I'm seeing after the new update.There's nothing we can do about it.
I have the s21 ultra 512 and have the same problem, i can not play my favorite game on it because it's sluggish and it sticks. I have done everything, even factory reset but still the same. I don't know if it is a hardware or software problem. I noticed is a bit better if you turn off the animations.
