You can see who has microphone access on your device through your operating system's settings, typically under Privacy or Security & Privacy, where you'll find a Permission Manager or a dedicated Microphone section listing apps with access, allowing you to toggle permissions on or off. On phones, an indicator light (often orange) shows when the mic is active, while Windows and Mac also have system-wide microphone indicators and detailed settings.
Go to Settings > Privacy (In Windows 11, it's Settings > Privacy & security). Select Microphone under "App permissions." Here, you can see which apps have access to your microphone and toggle access on or off.
Select Start > Settings > Privacy & security. Then look for Microphone under App permissions and make sure Microphone access is turned on. Then, allow apps access to your microphone. In Microphone settings, go to Let apps access your microphone and make sure it's turned On.
Open Settings > Privacy > Permission Manager. Select Camera or Microphone. Choose which apps can access them, and adjust permissions as needed.
There's no specific code that can tell you if your phone is tapped. However, USSD codes like *#21# can show whether call forwarding is enabled. And if you find that call forwarding has been enabled, then you can use ##002# to disable it.
App permissions that enable listening
Apps installed on your phone can request access to the microphone, often whenever you install or first use them. Of course, many apps have clear use cases for this, such as voice recorders, video chat, speech-to-text, hands-free access, and other accessibility features.
Listen for strange sounds in calls
These sounds can indicate that someone is listening to or recording your video call. Some people report hearing the sound of a camera shutter, static, clicking, or echoes.
How to Tell If Your Phone Microphone Is Hacked
Manage your camera & microphone in Quick Settings
You can also access camera and microphone controls from Quick Settings tiles. From the top of your screen, swipe down twice. To turn off camera and mic access, tap the camera or microphone tile.
To test a microphone that's already installed:
Use a Listening Device Detector App
Some of the best apps for detecting hidden cameras and microphones include Hidden Camera Detector Free for Android and Hidden Spy Camera Detector for Apple. Listening device detector apps scan the area using an infrared scanner or the phone's magnetic sensor.
Now, pay close attention to the ads you see on your phone and online, including banner ads on websites, on your social media feed, ads within apps and even advertisements on your Smart TV. If you start seeing ads tied to your topic, it's safe to say your phone is listening, even when you don't use the wake word.
This green dot is a tool that allows you to know when an application is accessing the device's camera or microphone in real time by displaying a green dot at the top of the notification panel. When viewing or scrolling through the menus, you can see whether or not some apps use the camera or the microphone.
Key signs that your phone is under tracking or monitoring
Dialing *#21# on your phone uses a USSD code to check the status of your unconditional call forwarding, revealing if all your calls, data, or texts are being redirected to another number without your knowledge, which can happen if someone accesses your settings. It's not a definitive hack detector, but it quickly shows if a carrier-level setting is diverting your communications, potentially to intercept sensitive information like 2FA codes, and can be disabled with ##21#.
Can your phone hear your conversations? Yes, it can. As voice assistants and some other apps need access to your microphone, they may record your conversations and phone calls. In the process, they often collect private information you didn't intend to share.
Just as you might cover your webcam to avoid secret monitoring, you can also cover your microphone with a piece of tape or purchase a special phone case to stop your phone from listening to you—just remember to remove it before recording or making a call to avoid muffled audio.
How to stop someone from listening to your calls on an Android phone
Call trace allows you to dial the code *57 to trace the phone number of a call that was received. This service is used to trace harassing calls which warrant law enforcement or legal action. If you do not intend to take legal action, then an alternative is to use Call Return with *69.
Monitor the applications running in the background of your device and check whether there are any unknown applications. Notice significant increases in device temperature and decreases in battery life. These often indicate your Android device is being accessed remotely.
Use a Protective Case
They not only keep your phone safe in general but they may help protect your camera lens. You want to look for a case with a raised bezel, which essentially means that the case has a sort of ridge that surrounds the camera lens.
