Lumia 620 restarts automatically after WP8.1 UPDATE 1 DP

[Paragkharche007]

I used my lumia 620 after windows phone 8.1 update 1 with Lumia Black firmware for some days and after Cyan available I am using same update 1+ lumia cyan, But I am getting same issue both the time that phone restarts automatically. I guess it is app folder issue which occurred way back when there was app of Nokia App folder.
