Hi! I understand you're having an issue where the Easy Line Remote app on your Android 10 phone is preventing your phone’s microphone and speaker from working properly during calls. Let’s work through this together.

To get started, may I ask a couple of quick questions?
1. Does the microphone and speaker stop working only when the Easy Line Remote app is running, or also during regular phone calls without the app?
2. Have you noticed any specific errors or prompts when you try to use the microphone or speaker?
3. Have you recently updated the Easy Line Remote app or your phone’s Android version before this issue started?

Meanwhile, here’s a step-by-step approach you can try, tailored for your Android 10 device:

1. Check App Permissions: Ensure that Easy Line Remote has permission to access your microphone and speaker.
- Go to your phone’s Settings > Apps > Find and select Easy Line Remote.
- Tap on Permissions.
- Make sure Microphone is allowed. If it’s denied, enable it.

2. Restart Bluetooth and Hearing Aids:
- Turn off Bluetooth on your phone, wait 10 seconds, and turn it back on.
- Restart your hearing aids (if applicable).
- Reconnect to Easy Line Remote and check microphone/speaker function again.

3. Close and Reopen the App:
- Fully close Easy Line Remote (swipe it away from recent apps).
- Reopen the app and see if audio functions restore.

4. Reinstall the App:
- Uninstall Easy Line Remote.
- Restart your phone.
- Reinstall the app from Google Play Store.
- Give the app microphone and Bluetooth permissions on setup.

5. Check for Conflicting Apps:
- Some apps can take exclusive control of your microphone or Bluetooth.
- Try disabling or uninstalling other hearing aid or call management apps temporarily.

If you have already tried some of these steps, please let me know, and I can suggest more advanced troubleshooting such as checking Bluetooth profiles or possible system conflicts. This is a known issue sometimes related to connection repair or permission glitches in Android1 5.

Are these instructions clear, and would you like to proceed with these steps? Also, please share what you’ve tried so far!
