I am using S21 FE 5g 888. After updating december security patch, I can see burn pixel on screen after using instagarm and other apps too. At the bottom of the screen I can see instagram navigation buttons like home, reel and profile.
There no such heating issue or any other issue, I always use dark mode and dark wallpaper. My phone is in warranty.
As per your query, We request you kindly visit the service center for a physical inspection of your device. So that they can check the exact issue with the device and fix it at the earliest.
Is there problem of screen burn had solved or not ? Even I'm using the same device and from 2-3 days I faced the same problem.....but it disappears after some time
