I use my phone with the location tile toggled off, but am unclear if this is enforced for system apps. Privacy dashboard shows ImsService accessing location once or twice per hour. My shallow understanding is IMS allows VOIP, VoLTE, VoWiFi, PoC, and carrier video calling. I use a Verizon MVNO.
Can location permissions be revoked from ImsService without breaking functionality? Would revoking location permission provide any real privacy benefit since Verizon already knows phone location based on cell sites?
Thanks to anyone who can help me better understand the technical implications of IMS and location permissions!
