Originally I've download the signal app through playstore, but often it also get updates from Droid-ify(Fdroid client). Today its weird and I got this . Explain to me this.
On the Droid-ify the signal app is provided by: org.thoughtcrimes.securesms
Didn't notice the "droid-ify" part, whatever that is. Install apps from trusted sources like F-Droid or dev's website and you don't need Google to scan your phone and tell you what you can or cannot install.
Fully foss dependencies, degoogled (doesnt require Google Play services), and further hardening to the app. And you can still keep your signal contacts since it is just a fork. Available through Accressant, fdroid, and github.
