I turned on a child's app that my granddaughter loves to make sure it was working as she is coming to visit. The app worked but it also locked up my tablet. I have tried the power + volume button; the power + home button but neither worked. It will turn the tablet off but when it comes back on the app is still there. Any ideas???
