i initially got a 6plus. i was having a lot of problems so i sold it and got a 6. i realized i got used to the big screen and battery life. the problems i were having with freezing and other stuff. it was annoying but i could deal with it. battery life was the best. the 6 just seemed smaller. so i spent a bunch of money to realize i should of stuck with it. now i started this one with a fresh install. so hopefully no problems. it shipped with 8.3. maybe the new builds are better. the camera actually seems a little better actually in sharpness. but time will tell.
