As it was previously announced, all icons have disappeared after the update.
But that’s actually not my problem. I have set back all icons to their original locations, and then started my Fairphone new, to see if everything works. After the restart, almost all icons were gone. Only those that were originally installed on the Fairphone are still there (like the browser, camera, …). I have put the apps several times again to the place where I wanted them, but to no avail: Once you reboot, all are gone again.
Has anyone had the same problem and can help me?
