S5 wakeup now slow after recent update. How do I fix?

AC Question

Did the update on 3/14 and I went through today deleting old files (from past games that have been removed from my phone for a while) as well as transfer the cds I have on my phone to my memory card. Since doing that, I've notced that when I press the side button or middle button to wakeup my phone, it is laggy. It fades in slow but remains black for a second or two before fading in to the screen.

I tried removing my memory card and trying it. It's not my memory card causing it. And it's just if the phone sits for a decent time too. If I make it sleep then immediately wake it it's super fast like it was before. Any ideas? I have removed the cache. That didn't help
