This feature only exists, because the people behind Signal actually care about freedom and want to help their users. Unlike WeChat, Signal is not built by any government to spy on people, and unlike commercial messengers like WhatsApp and Facebook Messenger, it's not built by a corporation that wants to extract money from their users by selling their data. It's a non-profit organization, created by people who are dedicated to make the world more private and secure. Just keep that in mind when choosing a messaging app.

Probably not the solution that you are looking for, but maybe try Signal? It's better than SMS, WeChat, WhatsApp and most other messengers. Unlike stuff like WhatsApp and SMS, Signal can even be used in China, because it has a built-in censorship circumvention system which uses special TLS proxies or can even be used over Tor.
Exodus does exactly what it's supposed to. It's your interpretation of the data that is flawed.
It's basically the same, the isolation is done by Android's work profile. Shelter and Island are just frontends for this native Android API.
Basically 2 options: A work profile or a separate Android user profile. I'd definitely recommend the latter, as it has much stronger isolation. Some vendors like Samsung disable user profile support though. A work profile is still better than nothing.
What's that Gallery app?
I knew I would get a comment about this. Yes, I absolutely know that Linux is not at all immune to malware, but the chances of finding Linux malware on a typical piracy website are very low. That's why Anti-virus is unecessary on Linux.
Rooting isn't recommended anyway, it completely destroys Android security. GrapheneOS is the best solution.
Absolutely. My entire network is behind a VPN, so they can't fuck up. Windows is banned in my household, so I'm not worried about malware. I'm not paying 20 bucks a month for limited access to the ever shrinking Netflix library, which I can't even use behind a VPN or share with other people. Piracy is the only way forward.
Both are open-source and there's a fork of Island on F-Droid called Insular. These shouldn't collect any data, in fact, they can't include any proprietary tracking SDKs because these aren't allowed on F-Droid.
