App installed from F-Droid and updated via Playstore?
I have installed Davx5 from F-Droid, from IzzyOnDroid Repo. Today I have checked for updates with the Google playstore and the App was updated to the playstore variant. I thought this isn't possible? What's going on here?
You're viewing a single thread.
The apps on IzzyOnDroid are built by the original developers and likely signed with the same key as the version on Google Play. As a result, Google is able to update them. Apps in the official F-Droid repository are signed by F-Droid. As a result, the keys are different and won't be updated by the version from Google.
It can also happen with apps from the main repo. If the app is reproducible (about 5% so far, most new apps) then F-Droid will use the developer signature.
This makes sense. Yes, I have paid in the playstore for this app (and I would do it again and again). But if I understand it correctly this would also mean, I could download their v4.3.8-ose from the official GitHub repo for free, and it would be updated automatically from Playstore to v4.3.8-gplay version (which is not free). Strange.
But this app is worth every penny.
