iPhone XS screen flickers during boot up
When my iPhone XS boots up, the screen momentarily flickers and shows grains around the apple logo. This happens for a split second and then vanishes completely from the screen.
The issue does not occur at any point after the phone is up and running. Also toggling truetone mode on/off does not help.
Please advise if my device faulty? Though the issue does not seem to hamper normal use, it is disturbing to see it occur consistently.
