I know there are other messages about this elsewhere but I still can't figure out why I am still getting this message, along with "phone storage space is getting low". I have cleared caches, tried to uninstall apps but most "uninstall" buttons are greyed-out. Android Assistance shows I have plenty of room left. I have Googled and Youtube-ed for the answer with no luck. I am not very technologically advanced so plain English answers would be appreciated. If you know of a link in here that has the answer please direct me to it. AND on top of this annoyance, now I seem to be getting pop-up crap when I'm in Tools/Startup Manager/System when I try to select items to kill on startup. they don't get killed and I'm getting little advertisements along the bottom. Right now I see one for a Dunkin' Donuts app for crying out loud. Thank you.
