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
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.
