@keneda yeah, exactly i thougt about touch keys under cover of the phone. I understand that ubuntu touch works on gestures but i think that this would be grate idea to create some shortcuts to some applications/functions. A lot of phones have additional keys on cover for example mi 9 (to google services).

@ganzredmi4 Hi, same xiaomi 4X, just installed today. Had a first unsuccessful attempt with the same description of events as you. At the secound and successful attempt, i simply waited, quite long, for the device to finalize its complet setup.
I msy have waited for more than ten minutes. And yes, it tells you that it is going to reboot, after all the completion of the process. Be well, peace
