It seems to be a long time bug
I dont think it is a GDR2 bug. I had been using Lumia 900 until few weeks back and I always had this issue with it, but was something I could live with it.
I thought WP8 doesnt have it as I didnt face it with my L920 in last 3 weeks.
What apps are you looking for?
Yeah I've got it as well, touchscreen isn't responsive unless I hit the power button again. It happens to me very occasionally, I think it's a GDR2 bug or something
