What is this?

 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??

Most likely a dead pixel. Nothing to worry about.

If you switch to landscape (activate auto rotate ) and rotate the phone to land scape .7 If the dot stays on the battery it belongs to the battery, if it stays on the same spot on the screen it is a problem of the screen, fear it is the second issue

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.

I know there's a light sensor on the s10 which normally flashes really really dim.
