Changing when a device cleans the device
memory
By default, the memory cleaner application runs on a BlackBerry device when the device is inactive for a specified period
of time. You or a
BlackBerry device user can change when the memory cleaner application runs when any the following
conditions exist:
• The user synchronizes the device with a computer.
• The user locks the device.
• The device locks after it is inactive for a specified period of time.
• The user changes the time or time zone on the device.
To change when the memory cleaner application runs, you can use IT policies or the user can turn on or turn off the
memory cleaner application in the Security options on the device.
You or the user cannot turn off the memory cleaner application on the device if any of the following conditions exist:
• You or the user turns on content protection on the device.
• An application uses the RIM Cryptographic API to create a private key or symmetric key.
• An application that registers with the memory cleaner application requires that memory cleaning application be turned
on.
• The device user installs the S/MIME Support Package for BlackBerry smartphones on the device and a private key
exists on the device.
• The user installs the PGP Support Package for BlackBerry smartphones on the device and a private key exists on the
device.
If you or the user turns on the memory cleaner application, based garbage collection process uses the memory cleaner
application automatically. The garbage collection process overwrites data that the device no longer uses.
For more information about the IT policy rules that you can use to change when the memory cleaner application runs, see
