From you home sceen pleas follow this steps:
Step 1: View the running apps on your device. How you do this depends on your phone and the Android version.
- Option A: Swipe up from the bottom of the screen (but don't swipe too far up or the app drawer opens).
- Option B: the small square icon on the bottom of the screen.
- Option C: the physical button on the bottom of your phone or tablet that looks like two overlapping rectangles. You might not see it light up until you press in that area next to the Home button.
- -Option D: On Samsung Galaxy devices, press the Recent Apps button to the left of the Home button.
Step 2: Swipe up and down or left and right (depending on your phone) to find the app you want to close down.
Step 3: Swipe up on the app you want to kill, as if you were throwing it off the screen. This works if your apps are listed horizontally
Or, for vertically listed apps, swipe the app left or right to close it immediately. On some Android devices, there's an exit button in the upper-right corner of each app when in this view, and you can tap it to close the app. If you see a three-lined button at the bottom with a small x on it, tap it to close all the recently opened apps.
Step 4: Repeat steps 2 and 3 to close the other running apps. When you're finished, select an empty space next to the edge of the screen or press the Home button.
