The Low Memory Manager (LMM) is activated automatically when the available flash memory on the BlackBerry® smartphone decreases to less than 400 KB. Flash memory is used to store BlackBerry® smartphone applications such as messages, calendar, contacts, tasks, memos, and third-party applications.
By removing rarely used applications and old data, BlackBerry® smartphone users can increase the amount of memory on their BlackBerry® smartphone. The LMM begins by removing low priority items such as cached data. Medium priority items, such as very old email messages and out-of-date calendar entries, are deleted if additional memory capacity is required. If the memory situation on the BlackBerry® smartphone becomes critical, the LMM will cause the email application to remove email messages on a last-accessed basis.
To view the available memory on the BlackBerry® smartphone, perform the following steps:
For BlackBerry® Device Software 5.0 and earlier, go to Options > Status > File Free
For BlackBerry® 6 and BlackBerry® 7, go to Options > Device > Device and Status Information
Note: Calendar entries and email messages removed by the LMM are not reconciled back to the mail system.
