- BlackBerry® Smartphone
The Keep Messages option allows configuration of the number of days to keep email messages, SMS messages and PIN to PIN messages on the BlackBerry® smartphone. After this period of time, email messages are automatically removed from the BlackBerry smartphone.
This is how message clean up works:
If system clock is updated manually or automatically which is every minute.
If smartphone is idle for at least 30 seconds.
If last clean up occurred more than 24 hours ago.
Then run clean up for those messages that are on the Smartphone past the Keep Messages setting. The date messages were received on Smartphone is compared with the Keep Message setting, and if the difference in days is more than/equal to the setting, the corresponding messages are cleared.
The clean up process would be run once a day max since we have a 24 hour last check condition. The first time the process would be run is 24 hours after the first time update (switching Smartphone on, or network update from carrier etc.)
If the Smartphone is not idle for at 30 seconds then the Keep Message option will not start. The idle time on the Smartphone is checked as follows:
Last interacted with the keyboard or holstered the Smartphone.
If there are any high priority messages in the queue.
If the phone is active.
If over the air software loading (OTASL) is in progress.
Is a wireless synchronization (backup or restore) in progress.
