My nothing phone 2a is less than a month old ,and already has screen retention of status bar icons and instagram icons at the bottom.95% of the units shall have it just check under grey screens
There is also a problem of uniformity of the display that can be checked by the inbuilt hardware test “*#*#0#*#*”.
There is also a bug in the lock screen.If you lower your brightness completely and pull down the control centre/notification panel,just see what joke of a display this is .
Dont know what to do ,i love the phone but the display quality is trash.
