A:Answer My stays connected to one device, it does not list devices and let you choose. I had to disconnect the signal on alexa to use samsung phone. I am not tech smart, but got frustrated trying to have a list of devices and just cut signal off of alexa then Samsung took. It always stays connected to alexa, but not phone.Oh it says all phones have that NCF Sony thing and you just tap the phone on the speaker to connect. I can not find a NFC Setting on my J Series Crown, Samsung.That would be great to just tap your android on speaker, I put the NFC easy connect on phone and it still will not tap, Its android 8 NFC I mean not NCF
