If you only set this up from your server and via VPN, the attack surface is of course more difficult. And setting up and administering a server is also something where you always learn something new. Everyone can do whatever they want with their phone.
I just wanted to point out that such an app should not be used carelessly via SMS and possibly with third-party service providers.
In addition:
- The phone must always be connected to the Internet.
- It usually doesn't help much if it's stolen.
- It's unlikely that I'd lose a device worth almost $1000, just like my wallet.
The point is: "find my phone" app is very needed. GOS does not offer it.
There is a good reason why the GrapheneOS developers did not integrate or removed the code for remote access and device locate.
