IPhone getting hot
Today I used my iPhone as a GPS device, while having it plugged into a car charger. I noticed that it got very got, particularly at the back.
This is the first time I've used the car charger, and the first time I've used the GPS app. It's also the first time the phone has got hot. Is it a fault with the phone? I have had it for just over three months and not had any problems with it so far, but this has worried me a bit.
