Restart the phone and report back, also, do you have enough free internal storage?

@noreena23 did you by any chance receive a message telling you to tap on the black dot emoji ⚫? it's been a popular prank in the past couple days, those messages bundle some invisible characters that make the Android apps freeze.

Hi. Actually I just got back my hp from Sony Service Center about 2 weeks ago after it faced that similar problems for few days and finally be put to silent death. So far I have not clicked any icon or things like that but the problems still occurring. Now, I'm worry that my hp will be put to silent death again and have to be couriered to Sony Service Center again.

Hi. Yes, I still have 40GB++ internal memory free. I already tried to restart but still like that also. My hp is still on warranty but I feel quite annoyed with that pop ups.
