Has anyone had this problem? When I slide my finger across the screen to go to my second page of apps nothing happens. If I tap an app to activate it, a square appears around the app but it does not activate. Sometimes it activates after tapping it 2 or 3 times but the apps generally do not actually operate. For instance if I tap on the Phone app the box appears. Then I tap 2 or 3 more times and it goes to the heppad screen but then I have to tap the numbers 2 or 3 times. The phone has really become a useless device.
