When starting the BlackBerry smartphone, safe mode can be used to prevent third-party applications from running automatically. Safe mode is designed to allow troubleshooting or remove any unwanted applications.
To turn on safe mode, complete the following steps:
- Remove and reinsert the BlackBerry smartphone battery.
- When the red light-emitting diode (LED) light goes out, press and hold the Escape key as the BlackBerry smartphone is loading. See KB05470 for the location of the Escape key.
- When the dialog box appears, click OK.
Note: Safe mode is indicated by a safe mode indicator in the BlackBerry smartphone status section of the Home screen.
To turn off safe mode, remove and reinsert the BlackBerry smartphone battery.
