Molly is only available on Android, as far as differences it is a hardened fork of signal with an encrypted database, what that means in practice is even if someone was actively probing your phone to try to gain access to messages they wouldn't be able to due to the encryption. It's very useful if you are an active target or you don't trust your phone os to play nice. I personally use it myself and really like it but in general it's not terribly different.
It's only encrypted in a BFU state, (before first unlock). Police can probe your phone for data using a tool by cellebrite without root. GrapheneOS includes a auto rebooting feature to place it back in a BFU state but other phones will lack this feature. Using Molly's database lock allows you to not trust the OS itself by encrypting it.
The main issue with encrypting the database using Molly's setup is you'll miss notifications and calls until you unlock, this might be able to be fixed using a different database encryption setup but as it stands it would be inconvenient for many.
Yeah I know it’s not on iOS I still love Android so I try to stay up to date on Android as well even not having one. My iPhone is paid for by work so I just don’t complain .
True but I work outside and have lost devices before sometimes it is out of are control and we still misplace devices especially when the fall out a pocket I was only pointing out I personally won’t use it for that reason is all I still would rather use Lineage OS over Graphene OS but I don’t think I will because of that one thing. I am looking at buying a used pixel hopefully soon.
the more third party apps you have, the higher your attack surface and a decrease in security. I love my mods but this isn't really a solution and should be an os feature.
find my device would be more difficult to implement without a decently sized company backing it but a lock out function wouldn't be that difficult. it just needs to be implemented into the os itself rather than rely on the trustworthiness of a third party dev.
