FBI used iPhone notification data to retrieve deleted Signal messages - 9to5Mac

The FBI was able to recover deleted Signal messages from an iPhone by extracting data stored in the device’s notification database.

As 404 Media notes, Signal’s settings include an option that prevents the actual message content from being previewed in notifications. However, it appears the defendant did not have that setting enabled, which, in turn, seemingly allowed the system to store the content in the database.

I’m curious if this is unique to iPhone and as an iPhone user, I wonder if there are certain settings we need to be aware of when using Signal.
