Keep in mind that factory resetting your phone will erase all data on the phone, so this works best if you've created a backup already. If you can't get your phone to turn on after it was frozen, a factory reset may fix your problem. Perform a factory reset if your phone is still frozen or won't boot. If an app keeps giving you problems, consider deleting it to avoid future problems.If you don't see this, tap App info first. If you can't close the app this way, open your Android's Settings, select Apps or Apps and notifications, tap the app you want to close, and select Force Stop.If you scrolled vertically, swipe the app horizontally to close it. If you had to swipe left or right to scroll through the apps, swipe the app upwards to close it. Swipe through the apps until you see the one that's frozen.Or, if you're using a Samsung model, tap the three horizontal lines at the bottom instead. If that doesn't work, tap the small square icon at the bottom of the screen (usually at the bottom-right) to display open apps.On newer Androids you'll usually do this by swiping up from the bottom of the screen, holding your finger, and then letting go-you'll see a list of currently-open apps. First, you'll need to display the open apps.If a particular app is frozen but you can still use your Android, it's pretty easy to force the app to close.
