Video calls keep families and friends close. But when the picture freezes or the sound drops out, the call feels like a chore. The good news is that most problems have simple fixes. You do not need to be a computer expert. You just need to check a few settings in the right order. This guide covers audio trouble, video trouble, and freezing. Work through the steps slowly. If one step seems too hard, ask a trusted friend or family member for help. Most calls start working again after two or three small changes.
Before you begin, know what app you use. Zoom, FaceTime, WhatsApp, and Google Meet all work a little differently. Still, the fixes are almost the same. Check your internet first. Then check the microphone and camera. A major rule is to restart your device. That fixes many hidden problems. Our website has step by step guides for how to use Zoom for beginners and how to make a FaceTime call. If you use an iPhone, our new iPhone setup guide shows the same menu locations.
Research shows more older adults use video calls than ever before. Pew Research reports that 61% of Americans 65 and older own a smartphone. More devices mean more calls and more small tech snags. The fixes below are safe and low risk. You will not lose your photos or contacts. You will only change settings. If a step does not match your phone exactly, look for words that sound similar. Android phones and iPhones use different names for some menus, but the idea is the same.
Work through each step in order. Do not skip ahead. Most calls start working after the first three fixes. If a step asks you to close an app, close it completely. If a step asks you to check a setting, look carefully. The words on your screen may look slightly different depending on your phone or tablet. Take your time. A calm, slow check is better than a fast tap in the wrong place.
What You’ll Need
- A smartphone, tablet, or computer with camera and microphone
- A stable internet connection
- Your video call app (Zoom, FaceTime, WhatsApp, Google Meet)
- A soft cloth for cleaning the camera lens
- Your device passcode or password for updates
How Do You Best Fixes for Video Call Audio, Video, and Freezing Problems?
- Check your internet speed and connection
Start with the most common cause: weak internet. Video calls need a steady connection. If your Wi-Fi signal is low, move closer to the router. If you use cellular data, move near a window. Test your speed with a free online speed test. Zoom recommends at least 1.5 Mbps for a one-to-one call. For group calls, you often need 3 Mbps or more. A speed test takes less than a minute.
Turn off any device that uses a lot of data. Video streaming, online games, and large downloads can slow your Wi-Fi. Ask others in your home to pause their streaming during your call. If your phone has a Wi-Fi Assist feature, turn it off. That feature can switch you to cellular without warning. On an iPhone, go to Settings > Cellular > Wi-Fi Assist. On Android, the exact path varies by phone.
If your Wi-Fi keeps dropping, try forgetting the network and reconnecting. This clears the stored password and starts fresh. You can also restart your router. Unplug it for 30 seconds, then plug it back in. Wait two minutes for the lights to settle. A restart often clears small router errors. If you are new to networking, our Zoom beginner guide shows how to check your connection inside the app.
- Close other apps and restart your device
When too many apps run at once, your phone or computer slows down. Video calls need a lot of power. Close apps you do not need. On an iPhone, swipe up from the bottom and pause. Then swipe each app up to close. On Android, tap the square overview button and swipe apps away. On a computer, close extra browser tabs and programs.
After closing apps, restart your device. A restart clears temporary glitches and frees memory. The steps are simple. On most iPhones, press and hold the side button and a volume button until the power slider appears. Slide to power off. Wait 30 seconds, then turn it back on. On many Android phones, press and hold the power button, then tap Restart. If you have a new phone, check our guide on setting up a new iPhone or setting up an Android phone for exact button names.
Restart the video call app too. Close the app fully, not just minimize it. Then open it again and rejoin the call. Many app glitches clear this way. This step also helps if your camera shows a frozen image or your microphone stays muted.
- Test your microphone and speaker
If people cannot hear you, your microphone may be blocked or muted. First, look for a mute button in the call window. It often looks like a microphone with a slash. Tap it to unmute. If you use headphones or earbuds, make sure the microphone is not covered by clothing.
Test your microphone outside the call. On an iPhone, open the Voice Memos app and record a short note. Play it back to see if your voice sounds clear. On Android, open Google Keep or the Recorder app and do the same. On a computer, use the sound settings. For Zoom, click the arrow next to the microphone icon and choose Test Speaker and Microphone. That tool plays a ringtone and records your voice.
Check your speaker too. If you can hear no one, the volume may be all the way down. Press the volume up button while on the call. If you use Bluetooth headphones, make sure they are connected and charged. Bluetooth can also cause echo. Turn Bluetooth off and use the phone speaker to test.
- Allow camera and microphone access
Most phones and computers block camera and microphone access for privacy. If the app has never asked for permission, the camera or microphone will not work. On an iPhone, go to Settings > Privacy & Security > Camera. Find your video call app in the list. Make sure the switch is on. Then go to Settings > Privacy & Security > Microphone and do the same.
On an Android phone, open Settings > Apps > [your video call app] > Permissions. Tap Microphone and choose Allow. Then tap Camera and choose Allow. If you see Ask every time, that is fine too. On a computer, use the browser or system settings. In Chrome, click the lock icon next to the address bar and check Camera and Microphone permissions.
If permission was already on, turn it off and back on. This resets the app. Then restart the app. If you have never set up these permissions, our new iPhone setup guide shows where to find them.
- Update the video call app and your device
Outdated software causes many video call failures. App companies fix bugs and improve performance in updates. Open the App Store on iPhone or Google Play on Android. Search for your video call app. If you see an Update button, tap it. On a computer, use the app’s menu or your browser settings.
Update your phone or tablet as well. On iPhone, go to Settings > General > Software Update. If an update is available, plug in your device and tap Download and Install. On Android, go to Settings > System > System Update. Updates may take several minutes. Do not interrupt them.
Apple’s FaceTime support page recommends updating iOS for best results. Google Meet and Zoom also publish release notes. An update can fix a known audio bug or a camera issue. If your device is very old, you may need to use a different app. Our guide to making a FaceTime call covers supported devices.
- Adjust in-app audio and video settings
Every video call app has its own settings. Open the settings menu during a call. In Zoom, tap More > Settings. In FaceTime, swipe up or tap the info button. In WhatsApp, tap the screen and look for the video controls. Look for audio output, microphone, and camera choices.
If your video is dark or blurry, check the camera quality. Some apps allow you to select a lower or higher resolution. Lower resolution uses less data. That can reduce freezing. Also clean your camera lens with a soft cloth. Smudges make the picture look bad.
If your voice echoes, lower the speaker volume or use headphones. If your video call lags, turn off HD video. In Zoom, go to Settings > Video and uncheck Enable HD. In Google Meet, the quality is usually automatic but you can send feedback. These small changes make a big difference on slow connections.
- Free up memory and lower video quality
Freezing is a sign that your device is working too hard. Close everything else. If you are on a computer, open the Task Manager on Windows or Activity Monitor on Mac. Look for programs using a lot of CPU or memory. Close them. On a phone, delete old text message threads and large video files. Use our guide on transferring photos from phone to computer to clear space without losing pictures.
Lower the video quality in the app. In Zoom, go to Settings > Video and uncheck HD. In WhatsApp, go to Settings > Storage and Data and choose Low Data Usage for calls. In FaceTime, the quality adjusts automatically, but you can enable Low Data Mode on your iPhone. Go to Settings > Cellular > Cellular Data Options > Data Mode > Low Data Mode. That can reduce freezing on cellular calls.
If the call keeps freezing, turn off your own video for a few minutes. Tap the camera icon to turn it off. See if the audio becomes smooth. If it does, your connection is too slow for video. Keep your camera off or call audio only. You can also switch from Wi-Fi to cellular or the reverse.
- Reinstall the app or try a different video call app
If nothing else works, delete the app and install it again. This removes corrupted files. On iPhone, press and hold the app icon, then tap Remove App > Delete App. On Android, go to Settings > Apps > [app] > Uninstall. Then go to the app store and install the latest version. You will need to sign in again, so know your password.
Try a different app to see if the problem is the app or your device. If FaceTime keeps failing, try WhatsApp video call or Zoom. If Zoom freezes on your computer, try the browser version. Sometimes one app has a temporary outage. You can check the company’s status page. Zoom, Google Meet, and WhatsApp all have service status websites.
If the problem appears in every app, your internet or device is likely the cause. Go back to Step 1 and check your connection again. If you still have trouble, ask a trusted family member or friend for help. Never call a random support number from a pop-up.
Red Flags & Warnings
- 🚨 Never call a phone number from a pop-up warning about a virus. Real tech companies do not call you first. Scammers try to get remote access to your device. Learn how to spot a tech support scam.
- 🚨 Do not share your video call meeting link with strangers. Uninvited guests can disrupt a call or record it. Only send the link to people you know.
- 🚨 Be careful with remote access requests. If a stranger asks you to install TeamViewer, AnyDesk, or another screen sharing tool, say no. End the call immediately.
- 🚨 Avoid public Wi-Fi for video calls if you talk about personal, banking, or health information. Use a private password protected network. See our online banking safety guide for more.
- 🚨 Do not pay for tech support with gift cards. Legitimate companies never ask for gift cards. If someone asks, it is a scam.
