Any update will come with things you don't like and like about it, as also hiccups.
I did a factory reset on mine after I did the update. That wipes EVERYTHING off your phone and sets it back to factory settings. Unless you have your data backed up, don't do it. I did it in hopes it would help me re-root, then I realized it was W8 that was my issue.
This was the only time I have done a FDR on my phone, I have always done the updates with no issues. Many phone techy types will tell you to do the FDR after every update but if my phone isn't acting up then why mess with it?
