I am mad and sad at the same moment when I saw that my whole phone got reset (blackberry PRIV). I lost all my personal data. It happened while as usual I was trying to play songs with out picking up my phone from my pocket using 'OK Google' feature. It played a song first but when I try again it didn't. I kept on trying for like 10 or more times. And just after like 5 mins when I checked the phone, it showed me a prompt asking whether I want to use Google launcher or blackberry launcher. When I selected blackberry launcher, it loaded the default apps. I was shocked and realised that my whole data is lost including installed apps.
Can someone please tell me what might have happened? And also I don't think there is any way but could I restore the data somehow?
Note: For each "OK Google" try, I need to press power button to wake up the phone.
