Since Friday my phone is heating up extremely when I use certain apps or camera. My phone is now 8 months old... suggestion please.
When I take video or photos, I get a notification on the screen that my phone is over heating. What to do? My phone is brand new, just over 1 month s8nce I had it. Nice features, but my S9+ didn't give me any problems.
I am very dissatisfied in the camera of my new phone. Focusing is terrible. Compare to S9+, the picture part went downhill. Video OK, but picture not so much.
