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 application data from Messages, Calendar, Contacts, Tasks, MemoPad, and third-party applications.
The amount of memory on the BlackBerry smartphone can be increased by removing rarely used applications and old data. The Low Memory Manager 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 Medium priority items, such as very old email messages and out-of-date calendar entries, are deleted if additional memory capacity is required.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 smartphone becomes critical, the Low Memory Manager will cause the email application to remove email messages on a last-accessed basis.
Note: Calendar entries and email messages removed by the Low Memory Manager are not reconciled back to the mail system.
To view the available memory on the BlackBerry smartphone, perform the following steps:
For BlackBerry Device Software 5.0 and earlier:
- Select Options > Status > File Free.
For BlackBerry 6 and 7:
- Select Options > Device > Device and Status Information.
