    So I have a lumia 640xl and upgraded to W10M last week via the Upgrade Advisor app.
    So far everything has been fine, no issues exept Alarms&Clocks crashing at the start, but a soft reset fixed that.

    But every night around midnight my phone restarts itself for some reason. Which is annoying, because if I have already went to sleep, I basically have no phone until I wake up, because I haven't entered my PIN and the sim card is not active.

    All I can think of now is that I had similar experience with a scheduled maintenance back on Windows 8.1, but it was easy to turn off from the control panel.
    On the phone however I couldn't find such option.
    I haven't done hard reset after the upgrade, because I didn't think it was needed. Any ideas if it will fix my issue?
    Here is some info about OS Build etc.

    It's definitely worth a try. Also check on the Windows Device Recovery Tool to see if there are any firmware updates available for your phone.
