I just observed whenever i unlock my phone using the on screen fingerprint or just by double tapping the screen while the phone is locked just to see the time the screen flickers.
I thought after the update this issue will be fixed and now im afraid that this might be a hardware issue.
I never had this issue on my other galaxy devices.
Great Samsung morning! I am very sorry to hear that you're experiencing this issue. No worries, I'll try my best to help you out. What I can suggest for you to do is to perform 'Soft Rest' to your device. Soft reset is one of the easiest ways you can rest your Android device. A soft reset means turn off your device and restart, it will shut all functions of your device and start it all over again. Doing this always refreshes your device clearing all running applications, which frees up the random access memory. Hope to have helped you out.

This happened to my A52 after updating the firmware from March 2021 release to the February 2022 release. From One UI 3 to One UI 4. I'm very disappointed because of it; and it seems a bit laggy :(
