    You said you reset your phone. Did you do a soft reset or a hard reset?

    See if this will help.

    You have to do reset. I didn't the same for my lumia 1020 and got it fixed.

    See proper way in youtube how to do reset using volume and power keys. It will show exclamation mark and the reset progress
