Home button stuck
My iPhone 7 plus all of a sudden did not work. Then I found out later that in only worked when I left it in a low temperature below 10 degree centigrade. It dies again, when I used it for a few seconds in my hand. To test if it was the fact, I put it in the fridge for a few minutes and tried the home button in my hand. It would died after a few seconds every time
