Screen recording captures what's on your screen, but not the audio from phone calls
A screen recording is a video file of everything displayed on your device's monitor or phone screen. It records the visual part—windows, text, videos playing, cursor movement—but the audio it captures depends entirely on what you're recording and how you set it up. If you're recording a phone call, the answer is almost always no: the call audio won't be in the file unless you've specifically routed it through your device's speaker or used software designed to capture call audio.
This matters because people often assume screen recording is a complete record of what happened on their device. It isn't. A screen recording of a video call on Zoom will capture the video and the speaker audio coming through your computer. A screen recording of you holding your phone to your ear during a cellular call will show your screen going dark or showing the call interface, but not the actual conversation.
Key Takeaways
- Screen recording captures only what appears on your screen's display, not audio from phone calls unless that audio is playing through your device's speakers or the app itself.
- Video call apps like Zoom, Google Meet, and FaceTime record both video and audio when you use their built-in recording features, but a basic screen recording of these apps may not capture audio depending on your device settings.
- Cellular phone calls (calls made through your phone's dialer) do not appear in screen recordings because the audio runs through your phone's cellular connection, not your device's speaker output.
- Recording someone without their knowledge or consent is illegal in many states and countries, even if you're only recording your own screen.
How screen recording works on phones and computers
On an iPhone, the screen recording tool (found in Control Center) captures video of your screen and whatever audio is playing through your device's speaker or headphones at that moment. If you're on a FaceTime call and the audio is coming through your speaker, it records. If you're on a cellular call, the audio is routed through your phone's cellular connection and doesn't pass through the speaker system, so it won't be recorded.
On Android, the built-in screen recorder works similarly—it captures the display and any audio playing through your device's audio output. Some Android devices let you choose whether to record internal audio, external audio (from your microphone), or both. On Windows and Mac computers, screen recording software like the built-in tools (Windows 10's Game Bar, macOS's Screenshot utility) or third-party apps like OBS Studio capture your screen and can be configured to record audio from your microphone, your speakers, or both.
The key distinction: screen recording captures audio that is playing through your device's audio system. Phone calls routed through your cellular connection, your phone's dialer app, or certain VoIP services may not produce audio that the screen recorder can access.
Which apps and calls actually get recorded
Video call platforms like Zoom, Google Meet, Microsoft Teams, and FaceTime route their audio through your device's speaker system (or headphones). When you screen-record during one of these calls, the audio is captured because it's part of your device's audio output. The same applies to audio playing from YouTube, podcasts, music apps, or any other media.
Traditional phone calls made through your phone's dialer app do not record their audio in a screen recording. The conversation happens over your cellular network or VoIP connection, and the audio is handled separately from your device's display. Some VoIP apps like WhatsApp calls, Skype calls, or Google Voice calls will record their audio if you screen-record, because these apps route audio through your device's speaker system just like video calls do.
If you need to record a phone call for your own records, you'll need a dedicated call-recording app or feature. Many phones have built-in call recording (common on Android, less common on iPhone depending on your carrier and state laws). These tools capture the call audio directly from the phone line, not from the screen display.
Why this matters for privacy and consent
Recording someone without their knowledge is illegal in many U.S. states and in many countries. The laws vary: some states require only one person in the conversation to consent (you), while others require all parties to consent. Even if you're only recording your own screen, if that recording captures someone else's voice or image, you may be breaking the law depending on where you live and where the other person is located.
Before you screen-record any conversation, check your local laws. In two-party consent states like California, Florida, Illinois, and Pennsylvania, you must tell the other person you're recording. In one-party consent states, you can record without telling them, but the law still applies to you—you can't share the recording in ways that violate their privacy. If you're recording a video call with someone in a different state or country, the strictest law in any location involved may explore.
How to record calls if you need to
If you want to record a phone call, your options depend on your device and what kind of call you're making. On Android, many phones have a built-in call recording feature in the Phone app—open a call, look for a record button, and tap it. Some carriers and third-party apps like Google Voice also offer call recording. On iPhone, call recording is not built into the native Phone app, but you can use apps like TapeACall or Rev Call Recorder, which work by creating a conference call and recording it (this method is legal in one-party consent states but may violate laws in two-party consent states).
For video calls, most platforms have their own recording feature built in. Zoom, Google Meet, Microsoft Teams, and FaceTime all allow you to record calls directly through the app. These recordings are usually stored in your account or on your device. Using the app's native recording feature is clearer and more reliable than screen recording, and it's the method most platforms expect you to use if you want to record.
If you're recording a call for your own reference or documentation, tell the other person first. It's legally safer, it's more ethical, and it avoids misunderstandings later.
Common mistakes people make with screen recording
The biggest mistake is assuming a screen recording is a complete record of what happened. It isn't. If you screen-recorded a phone call thinking you had audio, you probably don't. If you screen-recorded a video call but forgot to enable audio recording in your screen recording settings, you have video with no sound. Always test your screen recording setup before you rely on it for something important.
Another common mistake is recording without checking consent laws first. You may think you're in the clear because you're recording your own device, but the law cares about whether all parties to the conversation consented. Check your state's laws or the laws of the state where the other person is located before you hit record.
A third mistake is not telling the other person. Even in one-party consent states, telling someone you're recording prevents arguments later and is the more straightforward approach. If you're recording for legitimate reasons—documenting a business conversation, keeping a record of a technical support call—the other person usually won't object.
Frequently Asked Questions
If I screen-record a Zoom call, will the audio be in the recording?
Yes, if your device's audio is set to play through your speakers or headphones during the call. Zoom routes its audio through your device's audio system, so a screen recording will capture it. Make sure your device volume is on and your audio is not muted. If you want a cleaner recording, use Zoom's built-in recording feature instead—it's designed for this and gives you better quality.
Can I screen-record a text message conversation?
Yes, screen recording captures everything on your screen, including text messages. The recording will show the text but not any audio from the conversation. This is legal as long as you're recording your own device and following your local consent laws about sharing the recording with others.
Will screen recording capture audio from my microphone?
On most phones, no—screen recording captures audio playing through your speakers or headphones, not audio coming in through your microphone. On computers, it depends on your screen recording software. Some apps like OBS Studio let you choose to record microphone audio separately. Check your screen recording app's settings to see what audio sources it can capture.
Is it legal to screen-record a phone call without telling the other person?
It depends on your state or country. In one-party consent states, you can record without telling them. In two-party consent states, you must tell them first. Check your local laws before recording. When in doubt, ask the other person—it's the safest approach and avoids legal trouble.
Why doesn't my screen recording have any sound?
Most likely, your device's audio output wasn't being captured. Check that your device volume is on, your audio isn't muted, and your screen recording app is set to record audio. On phones, make sure the audio is playing through your speaker or headphones, not through a separate connection. On computers, check that your screen recording software is configured to capture audio from the right source.
