What does the flashing envelope in the top corner mean if it does not stop flashing alcatel ot 800?

The flashing envelope icon on an Alcatel OT 800 typically indicates that you have received new messages, such as SMS or MMS. If the icon continues to flash even after checking your messages, it could suggest a notification or alert that hasn't been cleared, or it may require a phone restart to reset the notification system. Additionally, you should ensure that your inbox is not full, as this can also prevent notifications from being cleared. If the issue persists, consider checking the phone's settings or consulting the user manual for further troubleshooting steps.
