Signal messages retrieved from iOS notification, as seen in Prairieland federal trial

TLDR: signal content in Apple notification can be retrieved even after signal app deletion.

I saw from this reddit thread: Signal messages retrieved from iPhone after uninstalling app. : signal

Referencing this news article: Pretti Killing May Affect ICE Prairieland “Antifa Cell” Terrorism Trial

The mention of signal is in court documents here: March 10: Federal Trial Day 12 - Support the Prairieland Defendants

Signal chat evidence from Sharp’s device (Exhibit 158):
Messages were recovered from Sharp’s phone through Apple’s internal notification storage — Signal had been removed, but incoming notifications were preserved in internal memory. Only incoming messages were captured (no outgoing).

Basically, they didn’t do this: (I’m on Android, so I don’t know what the options look like in iOS, but they should be identical.)

You also don’t need to do this on Android unless you are concerned about random people seeing the messages on your screen. Signal on Android does not use Google’s push notification service

It’s not about how it’s pushed. It’s how it’s displayed (and stored) on the phone.

Source? I am not seeing anything about that. The only problem I have seen on Android is when applications use firebase for notifications, which is most play store apps to be fair, just no FDroid apps or some privacy preserving apps

Android Settings>Notifications>History. If this is on, you can clearly see past Signal notifications, including sender name and message preview (if you enabled those in Signal). I don’t know whether there is any ‘hidden’ history/cache that is stored even with notification history disabled.
