The first thing you will want to do if you are encountering stability issues with your BlackBerry Priv, or have an issue with a specific app or game, is reboot your device. Doing so will close any running applications or processes and re-initializes hardware drivers within your device.

To reboot your BlackBerry Priv, press and hold the power key followed by tapping Reboot.

Test your device after it restarts to see if the issues have been resolved.
