HTC One - How to close Apps
How to close Apps
Android manages Apps very well and some Apps do not have the option to close them specifically. Normally the App will stay running in the background and only close when many other Apps have been opened.
If you do want to close or terminate an App, then press and hold the Home key on your phone. Then you can swipe the Apps off the screen to close them.
