Phonak Audéo Infinio Ultra Sphere 90 switching mode permanently

I have a Phonak Audéo Infinio Ultra Sphere 90 paired with my iPhone SE via Bluetooth and the myPhonak app. Normally, the app allows selecting different listening programs depending on the environment (e.g., Restaurant).

However, there’s a program called “Phone calls + mic” that should automatically activate only during calls and deactivate afterward. My ’s, though, keep switching back and forth between the “General” program and “Phone calls + mic” multiple times per minute, even when the iPhone is turned off.

I’ve tried:

  • Resetting the HA’s (15-second button press)

  • Turning Bluetooth off/on

  • Restarting the iPhone

  • Reinstalling the myPhonak app

  • Removing the HA’s from the Bluetooth list

This happened first with my original set of HA’s after a few weeks of normal use, and then immediately with a second set. Given that it occurs with two different HA’s, I doubt it’s a hardware issue. Even with the Iphone switched OFF, the problem remains. As if the HA’s are infected and remain infected, even when bluethooth can’t be found.

Has anyone experienced automatic program switching that persists even without an active phone connection, and is there a known solution?

This sounds like the problem I had about a week or so ago, and I don’t have an iPhone; I have a Samsung Galaxy S25 Ultra. I believe that the problem is the MyPhonak app.

I did the following:

-Cleared the cache for the app

-Force-stopped the app

-Restarted the phone

I hope that this helps! I’ll link to the thread (several people had very helpful suggestions there) and update this comment.

MyPhonak App suddenly haywire
Update: the problem seems to be solved now (hopefully permanently). I cleared the cache, force-stopped the app, and restarted my phone. After that I walked around the house and even ran the vacuum cleaner without any issues occurring. Thanks so much, everyone! Suddenly, this evening, my hearing aids started sounding “program change” tones every few seconds. I opened the app and it showed “RogerDirect + Mic,” which I didn’t choose, nor did I remember ever having that program before. I switch…

Thanks for the replies. Found the problem: my Mac was also connected and it seems that it always tried to interfere somehow. Switching off Mad bluetooth solved the issue. Just sharing this for future reference.

That was identically with my Surface Pro even when it was in sleep mode. Turned its Bluetooth off and problem was solved.
