Find my Device on GrapheneOS?

ThunderFarter You can install any messaging app you like. The general rule is if an app works on stock Android, it also works on GrapheneOS.

You will need to install Telegram from an app store. That could be Google Play Store, which is the easiest to use, but there are alternatives available. If you need any further help, do let us know.

ThunderFarter But i'm not so technical is there any way to use telegram or such instead of messaging?

For this to work you will need to grand Notification Access permission to FindMyDevice which would allow it to read all notifications and look for that "fmd" text to activate commands. Once this permission is granted, you should be able to use any app to trigger commands. To grant, open FMD, then go to settings (gear icon top right corner) then tap Permissions, next, next until you reach the screen about handling messages from other apps - and grant the permission.

There is an interesting app, called KDE Connect. You can install it on your phone and your desktop computer and they you can ring a phone from your computer.

Unfortunately it will not give you the GPS location... but at least it rings. There are some other options like file sharing, sending notifications from phone to desktop, you can send SMS messages from desktop...

But I am still looking for something, that will be sending you (encrypted) location to your server and be listening to "pings" from your server and then send location back to you...

Thanks, I already tested this app, and so far, it looks great: https://discuss.grapheneos.org/d/12867-find-my-device-a-possible-solution

I am using VPN, so KDE Connect is a viable solution for me. But this app (FMD) in much more useful.

It would be great if developers will solve open issues, and a security review of code would help too... Hopefully some day. :)

Matthai a security review

LOL. It is well known how insecure SMS is. People with a high thread level should definitely not install an app with these permissions. Something like this is a gift for attackers.

You see, you do not have to use SMS functionality. :)
Just do not grant rights and that is it.

The point is: "find my phone" app is very needed. GOS does not offer it. So people will look for alternatives. It seems this is the only alternative here.

Matthai what about Locus? Though it hasn't been updated in 7 months. Not sure if that means abandoned..

I think Locus is a different type of app. And it doesn't work on newer Android versions.

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.

Well, there is also good reason why people should use de-Googled phones. But they are not. And GOS decided, it is better to run Play services in sandbox, than to persist in orthodoxy. :)

I do not have a toothache, so we do not need dentists.

Tested https://gitlab.com/Nulide/findmydevice and it works good. Whitelisted 2 family members, they can send me a sms msg and receive a auto reply with coordinates via sms from my phone. If the phone is rebooted or sim card is taken out it still works because i have a esim without a pin, its always "online" if powered on.

i didnt opt in for the option to communicate location with a server (either self hosted or public) since the sms reply with geo coordinates is all i need.

Meph I tried a few weeks ago, unfortunately, Findmydevice didn't work for me because I have an owner profile and my main everyday profile. When installed in the owner profile and using my everyday profile it didn't work and when installed in my everyday profile it didn't work either...

Arnauld I also use 2 profiles, my main and a work profile. But it works.

Just noticed a issue though, I didnt open the app in a while and tested sending a location request sms from another device, and it replied with a location that was old. I wonder if this is because it wants a setting I don't want to change which is to use a terminal and do something like "pm grant de.nulide.findmydeviceandroid.permission.WRITE_SECURE_SETTINGS"

Meph I think its fixed now, app was not allowed to run in the background

Meph Thank you, I will try again then.

Meph How you enabled sms to work? If I try to give permissions for findmydevice, it show me that's not allowed and point to explanation with the URL, but URL doesn't work. On click nothing happens.

Well, I just enabled SMS permission and it works.

A bug maybe?
