New upgrade issues

[Bigmomma81]

I upgraded my phone to the new 5.0.2 version and it has been one problem after the next. My browser app doesn't work so have to access the Internet via chrome. My home button no longer works which means I can't flick between apps because I have to completely close out of things first. And the problems keep cropping up. Is there any way of removing the upgrade cause I prefer the old way alot more than this hassle.

Welcome to the forums!
There is no way to roll back to Kit Kat unfortunately, but you can try fixing your Lollipop issues by wiping the cache partition on your phone. The steps for the Z3 are here: https://support.t-mobile.com/docs/DOC-16654
