What can you try?

Try these safe, user-level checks in order; do not open the device. Menu labels may differ by version.

  1. 01

    Step 1

    Compare a normal phone call with a second calling app.

  2. 02

    Step 2

    Inspect the tips and microphone area externally using the maker’s guidance.

  3. 03

    Step 3

    Keep the phone nearby and confirm call audio is routed to Buds.

  4. 04

    Step 4

    Check Galaxy Wearable updates and available microphone settings.

  5. 05

    Step 5

    Test in a quieter area with another noise mode; never insert sharp objects into microphone openings.

How can you confirm the fix?

Make a short test call and record whether your voice or the caller’s audio is affected.

When should you contact service?

If the microphone issue remains across phones, seek a hardware inspection.

⚠ Stop using a device if it overheats, shows liquid damage, smells burnt or has a swollen battery.

Will a repair cost money?

Settings, cables and user checks may require no repair. Hardware costs depend on the exact model, warranty and service diagnosis; no fixed price is promised.

Quick answers

Could these checks affect warranty?

Use only external checks recommended for end users by the manufacturer. Opening batteries, electronics or sealed parts can create safety and warranty risks.

What if the steps do not help?

Write down your model, software version and test results. Share those details with official support rather than repeating potentially unsafe actions.
