Stop Restart App listed in Windows Phone Store to stop Windows Phone 8.1 models that randomly reboot

The Stop Restart App will stop your Windows Phone 8.1 model from randomly rebooting
As Microsoft puts it, "We’ve already made a fix that has resolved this problem for the majority of Windows Phones. However, some phones that have not connected to Microsoft servers still need the fix to be applied." When you open the app, it first checks to see if your handset has received the update. If you haven't received it, and you are hooked up to a Wi-Fi network, the app will install the fix right then and there. You do need to make sure that your battery is charged up before opening the app.
