Yesterday the touchscreen of my Fairphone 2 suddenly stopped working. It is not that the screen froze, because I can still use the volume button and see on the screen what is changing. If I press the the switch off button, I see the message to switch off your phone, but cannot press it. I therefore restarted the phone by taking out and putting it back in the battery. When I do this or when I press the off button for 15 seconds (to reboot is) I can use the phone as long as the screen does not go into sleep mode. As soon as this happens, I can press the off button to see the start screen, but the screen does not register any touches anymore. Once I restart it again, I can use it again (if I am fast enough before it turns into sleep modus, which happens if I am not paying close attention) until the screen go black… I took the screen off and I’ve put it on again, but this didn’t work. Afterwards, I did a complete reboot (back to the factory settings), but this did not work either.
Nothing peculiar happened to the phone, the problem just seem to appear from nowhere…
Did someone experience the same thing and now how to solve this issue?
