I bought Lumia 550 with Windows Phone 10 1,5 month ago.
And have a trouble with a phone, after unlocking, sometimes it reboots (I think something causes OS to crash), it often 10 or more times a day, depending on usage.
I downloaded Field Medic application and found reports of OS crashes(OS crash 00000175).
I tried everything from removing the SD card to hard resetting and Windows Device Recovery Tool. Nothing helped.
What do you think about OS crash 00000175 and what can I do other than going to service center?
