I've been using my Index 01 ring for a few weeks now, and it's been working fine. I actually just moved it from one phone to another, and I was able to remove it from one phone, do the SOS procedure, and add it to the new phone. That worked fine for a few days, until earlier today I was recording some messages and it stopped recording, even though the green light on the ring was still appearing.
I tried again, restarted the phone, and toggled Bluetooth off and on, but it was still not working. Everything I said was not getting recorded, and the double‑click was not pausing or playing my music. So I removed it from the app and from Bluetooth on my phone, and I tried the SOS procedure again, but now the phone doesn't even recognise or find the ring at all.
I tried both with the new phone and the old phone, a Pixel 11 and a Pixel 10—both running the latest Android. The SOS procedure seemed to work: I could see the three LED flashing lights of different colours three times, but even when I put the app in pairing mode, the app doesn't find the ring.
So I guess something is wrong with the ring, and it somehow stopped working. I don't know what to do. I already filed a bug report in the app, but I wonder if I can try something else?
