Today morning after a long taxi ride (I am travelling this week, persobal vacation), I took my phone from my pocket and it seemed to be turned off. I switched it on and the phone started up as it was the first time.

All my settings, config, apps, widgets were gone. I think the phone was factory reset. Not sure if it was locally (accidental click in settings?) or may be remotely. (The phone was fine earlier in the morning).

I tried to get the data from my Google account backup (which I remember setting up when I got this phone) but I could not (no 'Restore' option was enabled in settings. But that would be a different question). I had to manually (painfully) set up things again. All my photos ate backed up to google and I think I can get them back. Same for apps, most of the should have data on the cloud somewhere.

Is there a way to know what happened?

I have a HTC one (M7), and use Google for most services including back ups.
