Temperature Sensor
My iphone 6+ is out of warranty. It had some water damage. It's dry and starts but the Temperature warning comes up and only works if I place an ice pack over the screen and it needs to stay under 32 degrees. Crazy. I replaced the battery and heat shield on the LCD but that did not fix it. Is there an other temperature sensor located somewhere I'm missing that can be cleaned or replaced?
