I'm facing the same issue. It went unnoticed from my side as i use a back case. I guess its out of warranty now.

I'm facing a lot of UI stutter especially while scrolling in 120hz. Also the battery life has become pathetic now. I hardly get a screen on time of 4hrs. This is unacceptable for a flagship phone. The one plus 8 pro gives a screen on time of almost 8...

Is anyone from Samsung listening? I come from a One plus device and the support in the One Plus community was superb. Quick resolution and turnaround times. I dont think its the same with Samsung though.

I've updated my device too and yes I do notice a lot of stutter especially while scrolling thru items in Chrome and on whatsapp.

I agree that the device sometimes stutters especially while scrolling in chrome or messages in whatsapp.Its not constant though but is definitely noticeable
