FBI recovers "deleted" Signal messages through iPhone notifications

In a Texas terrorism case, the FBI reportedly recovered deleted Signal messages from an iPhone's push-notification database.

The messages had been removed from the app, but notification storage on the device preserved the content separately.

The phone belonged to Lynette Sharp, who had pleaded guilty to providing material support to terrorists.

The case highlights how operating-system features can expose chats even when end-to-end encrypted apps are used.

It also underscores the importance of device security and notification settings for Signal, WhatsApp, Telegram, and similar apps.
