Clear the phone cache

Did you clear the device cache after installing the update? See the "best practices" post for how to do that, as well as other post-update tips:

Already tried that but prb still there

I'm having similar issues so I tried this. The only option I have when I go to the menu is a factory reset. Am I missing something?

The wipe cache partition (WCP) option was removed with the February security patch. This is in line with other Android OEMs who have also removed that option from recovery. Seamless updates with A/B partitions make manually clearing device cache after a system update moot. 

WCP has apparently also been removed for devices older than the S25 and A55 series, that have traditional cache partition structures. I've seen some speculation that this is because virtual A/B partitions have been enabled for those devices. Samsung, of course, has not confirmed anything, but this approach would make sense.

Yes tried that too but the prb persists

Reboot your phone into Safe Mode and see if the problem disappears. If so, you have some malicious software running in the background in normal use which you will need to identify and uninstall.
