You can test your microphone on Android by simply using a voice recorder. However, if you need to know more about the secondary mic, as well, you should check for a built-in diagnostics app. Alternatively, you can use a secret code that opens the service menu or Quality Check options. These are the most common ways to test your microphone. If apps don’t have access to the microphone, make sure to grant necessary permissions. Sometimes a simple restart helps a lot. Learn about these two diagnostic ways below.
How do I test if my microphone is working?
The most straightforward way to test the microphone on your Android is to use the Voice recorder. All Android skins come with a built-in voice recorder so that’s where you should probably start. In case you can’t find a Voice recorder, you can get one from Play Store.
If you’re looking for some sort of diagnostic tool, this is not as simple as getting a voice recorder. Some Android skins come with a built-in menu of diagnostic tools while others require you to enter a dialer code that should bring up the service menu where you can test all device sensors. This includes a microphone test, of course.
On most Android devices, the code you’re looking for is *#0*# or ##64663## or *#*#64663#*#*. Just enter it in the Phone app and it should bring up the advanced service menu where you can test your microphone with the rest of the hardware. There’s no universal code so different devices require a different code. You should google your device and find out the exact code provided by OEM.
Samsung microphone test in the Members app
Samsung phones have a separate section under the Samsung Members apps where you can perform all sorts of tests, just like Motorola has Device Help. These are some built-in if not obvious ways to test your microphone and ensure that everything is working as intended.
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.
