For the last week or so my Iphone X has gotten so hot to the touch and the screen has went from bright to dull. This happens generally when I am watching something on it or browsing. When it happens I shut it off for a while and turn it back on (its still hot but cools down when not in use) Today it did it TWICE and I took it to the apple store. They ran a diagnostic test on it and said it was ok. I am puzzled as the temp of the phone is not the same hot as when you use it for more intensive things (software updates, fortnite, etc) its awkwardly hot. Anyone else ran into this?
