Yes, I have never used non-Nokia charger, but have this screen freeze problem. Keeps freezing, and while the soft re-boot gets the phone working, but it eventually re-freezes in 0-40 minutes.
I had this problem once earlier for 2 days or so maybe 3 months back, and some automatic software update solved the problem. Now I am having this problem again. Just think its a much better option to move to samsung S4, as my wife doesnt have any of these problems with her S4.
