Sometimes someone will call me and their photo will show as the phone rings. In the cases I'm referring to I've never added a photo to the contact---somehow the phone picks up their image over the Internet.
I'd like to register my photo in such a place, but how does it work?
I have had both iPhone and Android users call me and sometimes I get their "Photo Caller ID" for lack of a better term.
My phone is an HTC m8 running LineageOS 14.1.
Thanks for your help!
