Well my husband actually had to tweak some settings on our home router (NetGear) initially, and I was hooked up for several days without issue. Then last night, it was having issues connecting. I also had some freezing screens prior to uninstalling LP, no freezes since that I can recall.
Had my first force-close this AM, I was running Mighty Grocery and canceled a voice search. First time I'd done that, so I don't know if that's just a flaw in the app or what.
For apps I have:
Mighty Grocery
NFL Mobile (might uninstall, it was for my husband to play with and he said it wasn't auto-updating)
free thunderstorm wallpaper (not using it, might uninstall)
I had a couple apps I downloaded, didn't like, and uninstalled... LP, TrivialDroid. Might have been one or two more small things like wallpapers, can't remember.
