How to test microphone on Android (simple way)

You can test your microphone on Android quickly using the built-in Voice Recorder app. For more detailed hardware diagnostics (including secondary microphones used for noise cancellation), use secret codes or brand-specific tools like the Samsung Members app. These methods remain reliable on Android 15, Android 16, Samsung One UI 7, and the latest Pixel devices.

How do I test if my microphone is working?

The simplest and most universal way is to use your phone’s built-in Voice Recorder app (sometimes called Sound Recorder or Voice Memos).

Open the Voice Recorder app (search for it in the app drawer if you don’t see it).
Tap the red record button and speak normally for 10–15 seconds.
Stop the recording and play it back.

If your voice sounds clear with no distortion, crackling, or complete silence, your primary microphone is working.

Pro tip: Test during an actual phone call or WhatsApp/Telegram call — this is often the best real-world check.

You can also quickly test Google Assistant (“Hey Google”) to see if it responds accurately.

If the recorder works but calls or specific apps don’t, the issue is usually permissions or a software glitch rather than hardware failure.

Advanced diagnostics: Use secret codes

Many Android devices include hidden hardware test menus. These let you test the microphone along with other sensors.

Samsung Galaxy phones (including S25 series, Z Fold, etc.): Dial *#0*# in the Phone app (no need to press call). This opens the full hardware diagnostics menu. Look for Mic, Speaker, or Audio tests. You can test both the bottom (primary) and top (secondary/noise-cancelling) microphones.

Google Pixel phones (Pixel 8/9/10 series): Dial *#*#7287#*#* in the Phone app. This opens the official Pixel Diagnostics menu. It includes an Audio category where you can test microphones. You can run individual tests or a full diagnostic scan (requires stable Wi-Fi in some cases). The menu generates a report you can review.

Other devices (Xiaomi, Motorola, OnePlus, etc.): Common codes include:

*#*#64663#*#* or ##64663## (QC/Service menu on many Xiaomi/POCO/Redmi devices)
##0673## or ##0289## (Audio loopback test on various brands)

There is no single universal code. Search for “[your exact model] secret code” or “[your model] diagnostics menu” for the most accurate one.

Samsung microphone test in the Members app

Samsung makes it especially easy with the pre-installed Samsung Members app.

Open Samsung Members.
Go to Support → Phone diagnostics (or View tests).
Tap Mic (or Microphone).

The app will test both the primary and secondary microphones and clearly show results. This is one of the most user-friendly official tools available in 2026.

Bonus: Test secondary microphones with the Camera app (Samsung)

Many Samsung flagships have multiple microphones. Here’s a quick real-world test:

Open the Camera app.
Switch to Video mode and rotate your phone to landscape.
Start recording.
Speak normally near the bottom of the phone (near charging port) for a few seconds.
Then speak near the top of the phone.

Play back the video. You should hear your voice clearly from both positions. This helps verify the secondary mic used for noise cancellation during calls and videos.

In case you experience any issues with the microphone, make sure to clean it with compressed air and isopropyl alcohol. Furthermore, you should know that the main microphone is usually positioned at the bottom, next to the charging/data port. The secondary microphone is at the top. If your callers still can’t hear you during calls, you can perform a factory reset on your Android and check for improvements. If that did nothing, consider taking your device for repair.

With that said, we can conclude this article. Hopefully, you learned enough to test out the microphone and, with that insight, hopefully, fix the issue. If it doesn’t work in a certain app, make sure that this app has permission to access the microphone.
