How to Force Close an App on an Android Phone
Sometimes, apps on your Android phone misbehave and let you know. You see a warning on the screen announcing the app’s stubborn disposition. Touch the Force Close button to shut down the errant app.
When you see no warning or an app appears to be unduly obstinate, you can shut ’er down the manual way, by following these steps:
Open the Settings app.
On some Samsung phones, touch the General tab atop the Settings app screen, and then choose the Application Manager item.
Touch the Running tab to view only active or running apps.
Or you can swipe the screen to the left until the Running tab appears.
Choose the app that’s causing you distress.
For example, a program might not stop or might say that it’s busy or has another issue.
Touch the Stop or Force Stop button.
The program stops.
After stopping the app, try opening it again to see whether it works. If it continues to run amok, contact the developer. Choose My Apps from the navigation drawer and then choose the app to open its description screen in the Play Store. Scroll down to the bottom of the description screen and choose the Send Email option. Send the developer a message describing the problem.
