Android 12 One UI 4.0 problems..

[AshAnjum]

After updating to android 12, my s21 ultra is not running smoothly. Lagging, goes to 60hz most of the time, game is not working smooth and properly. Is anyone facing same issues after updating?

60hz issue is a bug available on US S21 devices, but seems to affect also International devices. Wait for next software update, it will fix all problems.

Do a factory reset

I am observing this only sometimes. So I feel this will fix soon. It's not a big issue.

Yes bro I'm also facing same issue on my S21 Ultra Indian Exynos variant

Nope. No such problems.

My S21 5g also has many problems. Outlook is not working, can't open links from Facebook, some other apps also not working.

Worst update. Lot of apps are crashing and not working. Seeing lag on scrolling on most of the apps. Lot of apps are not opening at all and crashing in start. Links not opening from Facebook.
