Hello, I have a Pixel 6 and recently put a SIM card in it. After adding the SIM card, this "Sim Toolkit" app showed up in the apps list and has the following permissions that cannot be changed.
- Sensors permission - Allow
I did not install any app from FDroid or anything like that. The only action taken was physically inserting a SIM card into the device. Under "App permissions > Sensors permissions", the "Allow / Don't allow" options are grayed out with a notice that "Device requires this permission to operate".
Additionally, it has the following capabilities
- run at startup
- query all packages (for what?)
- control vibration
- prevent phone from sleeping
The sensors permissions is concerning because, according to GrapheneOS, this means an app can "access data from sensors monitoring orientation, movement, vibration (including low frequency sound) and environmental data". This seems like a privacy hole if a cell network can access all of this through the sim card firmware. By "all of this" I mean things like sampling the gyroscope at high frequency to sample ambient sound.
Is there any way to disable the Sensors permission for this app (or the entire phone) so that it just gets all "zero" data from the gyroscope? I have no need for the gyroscope.
