FP1 - first model.
As should happen, the screen turns off after not touching the phone for X seconds (not sure how many). So far so good. However, I often cannot turn the screen on by pushing the power button. I have the feeling this happens more often when I directly try to turn on the screen, rather than let it wait for a while, but I’m not sure.
Occassionally, I wait for a minute and I can turn it on again, but quite often I have to reboot the phone.
