@VinceJ Good catch. You could forget too. On the iPhone, there is a choice to “Forget this Device.” I had the M90R and loved it for the clearer sound.
I had to return the M90R I had because I am having CI surgery in a week and a half due to SSHD and a ReSound aid is the only aid that syncs with the Nucleus 7 I am getting.
I was in a meeting, but had my iPhone on silent, thinking that would keep calls from ringing in my ear. Nope, my husband called me and I sent the call to voice mail by pressing and holding the button on the aid a couple of seconds. That was my first experience of that happening.
On the iPhone, I don’t know if it’s the same with Android, if you look in the bluetooth setting, you’ll see Phonak Hearing Aids listed twice or maybe four times if you have a left and right aid. Because I only had the left, my bluetooth would show L - Phonak Hearing Aid in my case (and possibly R - Phonak Hearing Aid for the right?) this would be the hearing aid. Then below it was LE_L - Phonak Hearing Aid, this would be the app. Now, I think I just disconnected the aid from the phone, not forget this device, anyway it caused me to miss a phone call. No ringing in my ear, nothing. All I did since the aids and program were still in my phone was to go into bluetooth and tap the the L - Phonak Hearing Aid on the list of devices. It would re-connect immediately. No turning off and re-booting the aids or the phone. I also think “Forget” would also work, but that would involve the phone to “search” for the aids. Now I have an iPhone and things could work differently in an Android device.
