  1. I recently took the update on my Galaxy S4. While a few of the new features are nice, I lost almost half my app icons and now it often takes several seconds for the screen to wake up. Anyone else having this issue? Is there a fix for this coming? I’d like to revert back to 4.3 if possible, but I’m seeing postings saying that reverting to previous versions is no longer possible.

    I loved the phone before the update. Now I’m getting frustrated with it.
