Galaxy s21 ultra too slow

[kkreddy]

After updating January 2022 update, phone becomes too slow. Sometimes can see yellow flickering on screen. I've never seen this issue in the past 1 year, but all these are coming up after updating latest security patch.

Please do try https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may also need to insert your earphones and or hook up to a laptop. No need to launch anything, just turn it on.

This is ridiculous. Why apps which are not in use consuming 3 gb of RAM. ??????

It's not clearning up automatically. Why Samsung ? ?

Reboot the phone and it should start working ok again although it will happen again at some point.

Tried many times.. it happens again.
This issue was not there before this Jan 2022 security update.

Yea I know it happens again but for me it goes away for a day or two before I need to reboot my phone again. It's a bug in the January update and nothing else you do will fix it on a permanent basis.

There is a also a lag issue with the Galaxy Watch 4 when you turn on the following setting:

Watch settings > Accessibility > Visibility enhancements > Magnification 

Enable the above and try entering your PIN, Dial a phone number and there is a 1-2 second lag on every key press!

I tried resetting phone, it didn't work.
I figured out it's with Adaptive screen refresh rate, where screen is not able to scroll smoothly. When I switch to standard, it's working as expected.

#samsung fix bug with Adaptive screen refresh in February update.

Thanks
