It's the hardware button at the bottom of the tablet's housing. This should prompt the app to minimize, allowing you to see the Home screen. Your app may take a few seconds to minimize if it is frozen. If the app doesn't minimize after around a minute, you'll need to restart your Samsung Tab instead. Press the app view button, which resembles two boxes in the lower-left corner of the tablet, then tap X in the upper-right side of the app's page. If the app isn't too frozen to exit this way, your app should close. If the app isn't responding to this, you can proceed with the rest of this method to force-quit the app. Tap the Settings app icon, which resembles an outline of a gear, in your tablet's App Drawer. You can also swipe down from the top of the screen and then tap the "Settings" quick icon. It's near the bottom of the Settings screen. Doing so opens a list of your tablet's installed apps. Scroll through your list of apps until you find the one which is freezing, then tap its name to open its page. This option is at the top of the page. This will cause the app to quit, though you may lose any unsaved progress in the app (if applicable). You may be prompted to confirm that you want to force-quit the app. If your app keeps freezing, you may want to remove it from your tablet:  Open Settings  Tap Apps  Scroll down and tap the app you want to remove. Tap UNINSTALL (if the app is a system app, tap DISABLE instead). Tap UNINSTALL or OK when prompted.
