Where is the microphone located on my Android phone?
Android phones come equipped with built-in microphones that allow you to make phone calls, record audio, use voice commands, and more. The microphone is an essential component that enables various voice-activated features on your Android device.
The main microphone on an Android phone is typically located near the bottom of the device, either on the bottom edge or on the lower rear side. However, many Android models will have more than one microphone, including front-facing microphones for taking selfie videos and noise-cancelling microphones. The exact number and locations can vary.
Knowing where the microphones are located and how they work is useful when trying to optimize audio quality and troubleshoot any microphone issues you may encounter. This guide will provide an overview of the typical Android microphone locations and features to help you get the most out of your device’s voice input abilities.
Main Microphone
The main microphone on most Android phones is located along the bottom edge or top edge of the device, usually near the charging port. According to Sources [1] and [2], the main microphone is typically found by looking near the charging port, where you will see small holes or vents. This is the primary microphone used for phone calls and voice assistant commands. The main microphone’s position allows it to best capture your voice when holding the phone up to your mouth during calls. While the exact position varies between Android models and manufacturers, checking near the charging port is a good place to start looking for the main microphone.
Secondary Microphones
In addition to the main microphone used for phone calls and recording audio, many Android devices contain a secondary microphone specifically for noise cancellation purposes [1]. This second microphone is located away from the main microphone, often at the top or bottom of the phone, and picks up ambient background noise in the environment. The phone’s software uses the audio input from the secondary microphone to analyze environmental noise and generate an inverted sound wave to cancel it out. This noise cancellation allows the main microphone to focus on the user’s voice more clearly.
The secondary microphone runs constantly while in a call to enable real-time noise cancellation. Its audio input isn’t affected by the user’s voice or close speech. Many Android phones like Samsung Galaxy models contain multiple noise cancelling microphones located along the top and bottom for enhanced directional noise reduction [2]. Overall, the secondary microphone(s) play an important role in improving call quality and audio recording on Android devices.
Check Phone Specifications
Each Android model is different, so the exact microphone location can vary. To find the microphone on your specific Android phone, check the user manual or specifications.
The user manual that came with your phone will often indicate where the microphone is located. There may be a diagram highlighting the microphone location or details in the technical specifications section.
If you don’t have the user manual, search online for your phone model’s specifications. The manufacturer’s website usually provides spec sheets with technical details like microphone placement. You can also find this information on phone retailer sites and technology review websites.
Knowing the exact model of your Android phone is key for finding the microphone location. You’ll get the most accurate results by searching for your phone’s model number rather than just the manufacturer and generic name.
With your phone model information, a quick online search should reveal microphone placement details. If not immediately apparent, look through diagrams and technical specifications closely.
Finding your Android phone’s microphone location may take some digging, but the user manual and online specifications will include those details.
Accessing the Microphone
Apps on Android devices need permission to access the microphone. When installing an app from the Google Play Store, you are prompted to allow or deny access to the microphone, camera, contacts, location, etc. By accepting, you grant the app permission to access the microphone when needed.
Many apps legitimately need microphone access for features like voice search, voice commands, audio recording, video recording with sound, calling/video chatting, live streaming, and more. Apps like Google Assistant, Alexa, social media apps, camera apps, messaging apps, video conferencing apps, and certain games may request microphone access.
However, some apps can abuse permissions and access the microphone in the background without your knowledge. According to MakeUseOf, “Some Android apps access your microphone (and camera) without asking. Or they ask for permission once, and then access these sensors whenever they want.” (https://www.makeuseof.com/apps-access-camera-microphone/)
It’s important to pay attention to permission requests. Check app settings to confirm microphone access, and only allow trusted apps to use the microphone as needed for features.
Microphone Settings
There are a few key settings you can adjust to control microphone access and performance on your Android device. To manage microphone permissions for specific apps, go to Settings > Apps & notifications > App permissions > Microphone and toggle access on or off for each app. You can also turn the microphone on or off system-wide through the Quick Settings panel – swipe down twice from the top of your screen and tap the microphone icon to toggle it on or off (source).
To adjust microphone sensitivity and volume levels, go to Settings > Sound & vibration > Advanced > Microphone. There you can use the slider to set the appropriate sensitivity for different conditions like noisy environments. Some devices also have options to reduce background noise and enable voice clarity for calls. You may need to experiment with these settings to optimize microphone quality. Just remember you can always toggle microphone access off globally if needed through Quick Settings.
Microphone Maintenance
Keeping your phone’s microphone clean and properly maintained can help ensure it functions optimally for calls, recordings, and other audio needs. Dust, lint, and debris can build up in the small microphone hole and affect sound quality over time. Here are some tips for cleaning and maintaining your Android phone’s microphone:
Use a soft brush – Gently brush around the microphone hole with a clean, dry toothbrush or other soft-bristled brush to dislodge debris. Avoid inserting the brush into the hole to prevent damage.
Use compressed air – Use a can of compressed air to blow out any particles in the microphone hole. Hold the can a few inches away to avoid forcing moisture inside.
Don’t use liquids – Avoid getting moisture in the hole by not using liquids, which can damage the microphone. Do not submerge the phone or use wet cleaning methods.
Check settings – Go into your phone’s settings to adjust microphone sensitivity if sound quality declines over time. This can compensate for minor dust buildup.
Inspect periodically – Check the microphone hole occasionally for any obvious obstructions, and clean as needed to maintain performance.
Protect the port – Use phone cases that adequately cover the microphone hole to prevent dust buildup when not in use. Avoid sticking anything into the port.
Seek repairs if needed – Take the phone to a repair shop if the microphone has stopped working entirely, which may indicate damage or a part failure.
With proper maintenance and care, your Android phone’s microphone can continue providing quality audio capture.
Microphone Troubleshooting
Most Android phones have multiple microphones to enable noise cancellation and improve call quality. However, microphone issues can still occur. Here are some common problems and solutions:
Microphone not working – Check your phone’s settings to confirm microphone access is enabled for your apps. Also, inspect your phone case and make sure it is not blocking the microphone. Restart your device and test the microphone in a voice recorder app.1
Muffled or low microphone volume – The microphone hole may be blocked by dust or debris. Try cleaning it out with compressed air. Also, check that your hand isn’t covering the microphone area during calls.2
Microphone only works on speaker – This often indicates a hardware issue with the phone’s main microphone. You can test by recording audio and checking if the recorded volume is very low. Your options are to get the microphone repaired or use a wired headset instead.3
Echo or background noise – Enable noise cancellation in your phone’s settings if available. Also, avoid making calls in very loud/noisy environments, and hold the phone away from your mouth slightly to reduce echo.4
If issues persist after trying the above solutions, contact your device manufacturer for warranty support or hardware troubleshooting.
