V1576064667106 , via OnePlus 9R , Sep 28, 2021 : I bought this OnePlus 9R by replacing my old OnePlus 6 mobile. The mobile was working fine for the first 2 to 3 weeks, later I started facing problems like the running application goes off, screen off for 10 to 30 seconds and come back to the home screen, day-by-day it started to increase... That's when I start to get the notification like the UI is not supported wait or close the application... Once click ok. The mobile is hanging for the next 1 to 2 mins before it come back to the home screen... I don't know what to do with this issue? Should I go for a replacement? I bout this mobile in Amazon and the return period is already over. Please help on this issue, to handle properly. Thank you.
