Every day it would ask me to update and I kept on delaying it and telling it another time...
Until today, when it popped up while I was using my phone and fingers hit it into the (apparently) pre-downloaded update.
Not wanting to brick it mid-update I let it go and am now on 4.3.
While I haven't yet rooted my device, I did intend to, but haven't followed along with rooting an S4.
So my question is, how screwed am I?
