Possible Compromise?

[deleted]

Hello, i'm using GrapheneOS for over a year now without any problems. I would considered myself as targeted, because i'm opposition in my country and we're pretty harsh treated here.

Now to my problem(?). Today i was scrolling through the permission manager in my main profile and under system apps i found something called 'lmsService' which i would consider very suspicious with it's permissions, it had pretty much everything enabled. I will attach pictures of what i mean. I don't have sandboxed play services installed on my main profile and have only FOSS-apps installed, so no whatsapp, etc. Is this something to worry about? Can i just revoke any permission without breaking my phone?

I hope it works: https://imgur.com/a/6Gn81VV

[deleted] This is a completely normal app from AOSP, please don't touch it or adjust its permissions, you'll just end up breaking functionality.

IMS service is responsible with giving you these special services from your cell carrier like VoLTE, WiFi calling, Video over LTE, SMS over IP and stuff. I would advise against touching any of the permissions and let it have all of them. I ended up breaking my SIM's call functionality by that and had to do plenty of resets to make it work again. But if you don't care about it, you can disable them at your own risk.
