I'm seriously thinking of going back to 4.1. I never once had a problem with that firmware and all my tweaks and themes worked fine.

Been having alot of problems with the text and phone apps lately. They would more often than not crash completely or take forever to load up. Also when making a call it would sometimes take over 10 seconRAB before it started ringing (that's happened before but it was once in a blue moon and only when I had a poor signal). Other apps have also been randomly crashing and taking forever to load. I want my old lockscreen back, I've went blue in the face trying to get it to work ever since 4.2 came along.

Has anyone else had these problems?

With the exception of find my iPhone and the personal hotspot it there really much else I will be missing out on...?
