Help! Today, I turned my Galaxy Tab 10.1 (1st gen) on and there's something funky going on. Several icons on the home page have changed to the green android robot. When I click on them, it says "application not installed". I go to the page that lists all the apps and there are a bunch there that have changed too. Instead of the robot, it's an SD looking icon but still say "application not installed".. These are apps like Maps and Samsung App Store too. Have rebooted to no avail. Thanks for any help!
