Product(s) Affected:

  • BlackBerry 7 OS and earlier
  • BlackBerry smartphones
  • BlackBerry Desktop Software

Call logs, Short Message Service (SMS) text messages, email messages, and calendar entries are automatically deleted from the BlackBerry smartphone. On the Status screen of the BlackBerry smartphone, the File Free field indicates low memory.

Important: Do not remove the battery from the BlackBerry smartphone.

Complete the following steps until resolution is obtained:

Step 1: Remove large, unnecessary applications that are installed on the BlackBerry smartphone.

  1. Determine the application space that is available on the BlackBerry smartphone by completing the following steps:

    1. Connect the BlackBerry smartphone to the computer. Open the BlackBerry Desktop Software.
    2. Select Applications
    3. Under the Application Summary section, note the total application space.
  2. Remove applications that are not required. For example, remove additional language packs and themes.

Note: Applications that are installed on the BlackBerry smartphone are stored in the flash memory. This limits the amount of memory that is available for other applications and application data.

Step 2: Remove data that is present on the BlackBerry smartphone that cannot be removed by the Low Memory Manager (LMM).

  1. On the Home screen of the BlackBerry smartphone, click Options > Status. For BlackBerry Device Software 6.0, tap All, then open Options > Device > Device and Status Information.
  2. Display the menu and click Database Sizes.
  3. Remove items that increase the size of the database. For example, if the contact list database is large, remove out-of-date contacts. If the Content Store database is large, move media files from the BlackBerry smartphone memory to a media card.

Step 3:
Modify the Device Memory Limit setting under the Media application.

  1. On the Home screen of the BlackBerry smartphone, click Media.
  2. Display the menu and click Options.
  3. Set the Device Memory Limit field to the lowest setting.
  4. Press the Menu key and click Save.

Some BlackBerry smartphones have integrated cameras without a media card. As a result, some features have been added to handle picture storage on the BlackBerry smartphone, including the following:

  • Reserved Pictures Memory: In BlackBerry Device Software 4.2.0, the default value setting is 10 MB. In BlackBerry Device Software 4.2.1 and later, the default value setting has been reduced to 2 MB. This setting reserves memory for pictures that the BlackBerry smartphone might take, and reduce the File Free amount that is displayed in the BlackBerry smartphone. This makes sure that the BlackBerry smartphone has memory available for pictures that are taken when a media card is not inserted in the BlackBerry smartphone. This setting can be reduced to 0.

    Note: The Reserved Pictures Memory setting does not prevent the BlackBerry smartphone from exceeding the specified amount of memory.

  • Device Memory Limit: The default value setting varies by the version of BlackBerry Device Software. This prevents the BlackBerry smartphone from storing more than the specified amount of memory use.

Step 4: If the File free value is 0 bytes, and does not increase after following the above steps, contact support.

In the Java operating environment, applications increase and reduce memory usage when applications:

  • Launch
  • Run required processes
  • Close processes

An application may use more memory than it is intended to use. If the File free value is 0 bytes, and does not increase, contact either the wireless service provider through which the BlackBerry smartphone was purchased or BlackBerry Technical Support Services.
