I've had my GS4 for a little over 2 months now. I'm running stock and still running 4.2.2. Everyday I defer the 4.3 update another 24 hrs because my phone works GREAT! All the features that I enjoy work perfectly and my thought is, If it's not broke, don't break it! At this point, would you go for the update or continue to enjoy the phone the way it is? Curious to read opinions. Happy New Year!
