Ordered my iPhone online from Apple and it was delivered yesterday. Shortly after activating I began to get a temperature warning on the screen. It pretty much shuts down the phone and says you can't use the phone until it cools. That notice will stay on regardless of the ambient temperature until I restart. Works fine for 2 minutes and notice returns. Took it to the Apple store today and they figure it's a faulty temperature sensor. Problem is, they have no stock to give me as a replacement due to demand. The staff was very helpful but I have to wait until Tuesday for another. Disappointing but not the end of the world. Just wondering if anyone else saw this, it's an iPhone 6, 64G.
