Phone compatibility

If you’re using a Samsung Galaxy phone on Android with One UI 6.x, you may experience Bluetooth disconnections or limited hearing aid functionality. The problem is in the phone software’s handling of Bluetooth audio profiles, not your hearing aids, as such we are working with phone manufacturers to resolve this.

Note, this workaround may not resolve the issue on all devices.

Pre-check

• Ensure your phone and hearing aids are updated.
  • Check for Android OS updates or fixes and install them.
  • Update your hearing aids to the latest firmware.

First-step workaround - to try if updates don’t fully resolve the issue 

1. Turn off your device.
2. Enter recovery mode:
   • Press and hold Volume Up + Side/Power button until you feel a vibration and the Samsung logo appears, then release.
   • Note: The exact button combination varies by device, so you may need to use Power + Volume Up + Volume Down or other keys depending on your manufacturer.
3. In Recovery, navigate to "Wipe cache partition":
   • Use the Volume Up/Down buttons to highlight the option.
4. Select it:
   • Press the Side/Power button to confirm.
5. Confirm the action:
   • Use the Volume buttons to highlight "Yes" and press the Side/Power button to confirm.
6. Reboot:
   • Highlight "Reboot system now" and press the Side/Power button.
7. After reboot:
   • Re-pair your hearing aids if needed.
   • Test the Bluetooth connection to verify if the issue is resolved.
8. If the issue persists:
   • Check for Android OS updates or fixes.
   • Update your Hearing Aids to the latest firmware

There are two ways to do this depending on the Android smartphone model:

Option 1:

1. Swipe down from the top of the screen to bring up the Notification Center
2. Swipe down on the Notifications Center to reveal the Quick Settings menu
3. Verify the Bluetooth symbol is highlighted, if not, tap to activate Bluetooth

Option 2:

Is there a fresh battery in the hearing aid or is the hearing aid charged?

Hearing aids with batteries

1. Replace the battery
2. Close the battery door to place the hearing aid in pairing mode
3. The hearing aid will be in pairing mode for three minutes
4. Follow the pairing process to connect your hearing aids to your Android smartphone
   

Hearing aids without batteries

2. Turn the hearing aid off and then back on to place the hearing aid in pairing mode
3. The hearing aid will be in pairing mode for three minutes
4. Follow the pairing process to connect your hearing aids to your Android smartphone

There are multiple ways to change the volume of a phone call when using the Bluetooth hearing aids:

• Using the volume control buttons on the mobile phone to adjust the call volume 
• The push button on the Bluetooth hearing aids themselves can be configured to adjust volume

For Smile hearing aids, when streaming a phone call, volume adjustments in the Remote Plus app will impact the volume of the streamed sound.

To ensure incoming calls are routed to the Bluetooth hearing aids, calls should be answered using the push button on the hearing aids.

1. Go to the Android phone’s home screen and navigate to the Bluetooth settings page (this varies depending on the smartphone model)
2. Tap on the slider button to turn Bluetooth on
3. Open the battery door of the Bluetooth hearing aids for 5 seconds and then close the battery doors to turn the hearing aids back on. If you have a hearing aid without a battery door, first, turn off each hearing aid by pressing the lower part of the button until the LED turns red (4 sec). Then turn on each hearing aid by pressing the same button until the LED turns green (2 sec).
