I am having a issue on using samsung facetime on my s10. I don't receive other facetime calls and cannot make one. I already tried the call settings and the facetime button wasn't there. What can I do?
"but on my s7 I could facetime other samsung users"
Video calling is a carrier provided service. If your S7 was a carrier locked device you probably were using the carrier's voice calling service. This is completely dependent on the carrier and usually only works between devices on the carrier's network.
Duo works on pretty much any device and across carriers. Samsung has integrated Duo into the latest few generations of phones so the Duo video calling button appears on the call screen and contact screen.
