When I switch on my 7024, the Coby logo comes on and then the android, then the screen goes white, (once it died while displaying 'android') and 2 seconds later it switches off. When I switch it on again it boots ok but the amazon appstore app and all the apps I downloaded through it force stop. I have to uninstall all of them, reinstall the appstore and then all the apps. It will then work for about a week and happen again. With good wifi reception I can reload everything quickly, still, I'd prefer if it didn't happen at all. No other apps are affected. I haven't been able to determine if any particular app causes the problem. I'd appreciate any help.
