Open OS prob: 2 of the 3 nav buttons not working

[Volker]

I assume it’s the same problem as mentioned here:

Notification bar, home button not working, system ui tuner not visible

Hi, since yesterday notification bar doesn’t open, home button and the button on the right of the home button don’t work at all. I tried to make the system ui tuner visible: it’s not possible. The display and the touchscreen are fine. I have a fairphone 2, android 7.1.2, fairphone open 19.08.1. Any idea? Does anybody knows something about Nova Launcher for repairing or about a another fixing tool? Thanks a lot!

So I’m afraid the only known solution seems to be a dic:factorydatareset.
