Thank you all! Obtainium sounds also very interesting! And for sure, droid-ify or Neo-Store, too.
AtriumCompound Thank you very much, so the problem would be, that many of the installed Apps could become problematic at the same time. And as I understand, from case to case, this could be more problematic with one app than another. Apps without network permission are less problematic I think?
Could that lead to a workaround in which one uses F-Droid for example for Apps without network permission only?
Another thing: F-Droid is criticized because updates do not alwayd come in time. But my experience is, that this is althoug right for Aurora Store at least with anonymous login. While on one phone, the Play Store updates an App, sometimes the update is shown on another phone in the Aurora Store several days later. Than sometimes it helps to restart Aurora a few times what also means to login with different anonymous accounts until there is one, that already gets the update.
Because of that, I assume, updates via Play Store are not rolled out to all users at the same time. Is this right? If so, Play Store would not really be better in this aspect!?
Thank you all very much!
