Have you been prompted to do the system update since the reset? Also, have you turned off your phone since then? I was locked out yesterday but after 30 min chat with Samsung I was able to get my phone to accept my password after a hard stop. The phone said "loading " for about 10 min then finally opened my home screen. However, last night I turned it off when I went to bed like I always have and then this morning it was asking for a password again even though I had set it up for swipe unlock. I am now locked out and doing a hard stop several times has not had the same result as yesterday.
