There are reports of volume issues after the update. If it ain't broke, don't fix it. And none of the updates listed apply to my phone. Battery life has been fine, I don't use MS Exchange, and I've not found the need to print from my phone yet. The only issue I do have, besides the wallpaper zooming after every reboot, is bluetooth volume control doesn't work on Win8.1, though it works fine on my desktop with Win7. Volume control works on both machines with a Galaxy S4, so I've at least narrowed down to the phone.
Anyhoo, I just did a factory reset trying to fix the BT issue (with no luck), and so far haven't gotten another notification about updating. Have only had the phone 2 weeks so may not be an option for other people, just throwing it out there.
