push notifications to work
by push notifications to work you mean?
Sandboxed Google Play is only considered an app in GrapheneOS. It shouldn't have direct access to the IMEI number unless it's explicitly granted permission.
I remember it being explained in the GrapheneOS FAQ that only the OS and the phone (dialer) app have access to the IMEI number. However, I'm not an expert, so I can't say for sure.
Could you please provide a link that confirms whether sandboxed Google Play or any app has direct access to the IMEI number? Thanks a lot!
