Why is the screen not working when it is left in a room of 18 C?
The screen isn’t able to turn on. It shows some funny coloured (mostly green and white) lines along the bottom of the screen when you try to wait the phone. Warming the phone on the body for 30 seconds or more allows the screen to turn on again.
It then works totally fine again until it is allowed to get cooler.
Is this a good question?
