iPhone X Lighting 3.5mm overheating
When using my 3.5mm adapter for my IPhone X (the OEM one), the lightning tip itself becomes so hot that it literally burns to the touch, and forces the adapter to disconnect streaming through the cable.
I have to reconnect the cable after this happens to play audio, and it only lasts a couple minutes until it over heats again.
Additionally, when the temperature outside is particularly cold (~30F), the iphone refuses to register touch and overheats after watching less than 5 minutes of video.
iPhone X, iOS 11.3
