Confirm that all installed third-party applications are approved for the device

Make sure that all third-party applications installed on the BlackBerry smartphone are approved for the device. If the issue persists, remove third-party applications to make sure these are not affecting performance.

Perform a hard reset

A hard reset is similar to restarting a computer that stops responding. A hard reset closes all running BlackBerry applications, restarts the BlackBerry smartphone operating system, and restarts the hardware components of the BlackBerry smartphone, including the wireless transceiver.

Note: A hard reset does not delete any settings or data on the BlackBerry smartphone.

To perform a hard reset, complete the following steps:

1. Turn the BlackBerry smartphone off.
2. Remove the battery.
3. Reinsert the battery.
4. Wait for the BlackBerry smartphone to turn on.

Note: If the issue returns after performing a hard reset, then contact technical support for further investigation.
