That tends to happen when you leave a bunch of apps running, I have a android phone that does that. Download an app manager, that should help a lot. But one thing you have to remember this is a the first actual tablet google has put out so there is going to be bugs and glitches, no one gets it totally right on the first try. I'm still going to buy one cause iv'e had some ASUS tablets and they work the best . So for those complaining about it i'm sure ASUS and Google will put there heads together to get this fixed and install a freaking app manager.
