I noticed this small dot above my battery icon. I have clean over it thinking its dirt but it has not gone, it also has not grown in size or anything. What is it??
Dial *#0*# in your phone app and look for the colour test panels and switch through those a few times to see if that jolts the pixel back into life.
If not then seek support from a Samsung Experience Store or Samsung Service Centre.

The advice I offer is my own and does not represent Samsung’s position.
