WhatsApp is one of the most popular instant messaging apps and is particularly well-suited for video calls. However, video calls may sometimes stop working unexpectedly. While there isn’t always an obvious reason, there are several possible solutions — from clearing the cache to restarting your phone.

Why is my WhatsApp video call not working?

Most WhatsApp users have encountered this issue before: WhatsApp isn't working — now what? Another common problem is when a WhatsApp video call doesn’t work or freezes. Since the cause isn’t always immediately clear, we’ll walk you through the most common reasons and practical solutions for when your WhatsApp video call isn’t working.

Note

As soon as you experience issues with WhatsApp, you should promptly create a backup of your chats and media, such as by setting up a WhatsApp backup with Google. In an emergency, you can then restore your WhatsApp backup.

Possible reasons why your WhatsApp video call is not connecting

The following causes could be responsible if your WhatsApp video call isn’t working:

  • Missing WhatsApp update
  • No internet connection
  • Data saving mode activated
  • No app permissions for microphone and camera
  • Flight mode activated
  • Possible malware infection
  • Problems on the call partner’s side
  • WhatsApp Server problems
  • Contact has blocked you
  • Group video calls don’t work on WhatsApp for PC or Mac
Tip

A local WhatsApp backup or copies stored in a free online storage service are helpful. However, it’s even better to back up important data, contacts, and chats in the highly secure HiDrive cloud storage from IONOS.

Possible solutions to try if your WhatsApp video call doesn’t work

There is no blanket solution when a WhatsApp video call is not connecting as desired. To solve the problem, you can try the following options:

  • Restart: Often, just restarting your smartphone will solve the problem. Turn the device on and off and then try calling again.
  • Internet connection: WhatsApp requires a connection to the internet. So, the call might end if you leave the Wi-Fi without activating your mobile data or if the connection has been interrupted. Check to make sure you are still online.
  • WhatsApp update: Your WhatsApp might not be up to date and needs an update. To check if you are using the latest version, go to Google Play or the Apple App Store. Check the WhatsApp page there. The app will automatically update itself or show available updates.
  • Device settings: Settings such as airplane mode or data/power saving mode can prevent a video call. In flight mode, it’s not possible to connect to the internet. So disable the mode if that is the case. If you have data saver mode enabled, turn it off before making a video call.
  • Virus scan: If the video call problems occur regularly, it’s recommended to run a malware scan with an up-to-date antivirus software.
  • Clear cache: Temporary files accumulate in the cache, which in rare cases can affect the performance of the app. Clear the cache by going to the settings on your device and then to the apps section. Here, go to the details page of WhatsApp and clear the cache.
  • Sync/restore contacts: Whether it’s individual or group calls on WhatsApp, if you’re having issues with the video, it may help to refresh your contacts via the bubble icon and then the three-dot icon. Likewise, it may help to resync your contacts via “Settings” > “Accounts”. Alternatively, you can restore WhatsApp contacts by using a backup.
  • WhatsApp reinstallation: If all else fails, you can first remove the app from the device and reinstall WhatsApp. Similar to restarting a device, some problems will solve themselves this way. However, be careful not to accidentally delete your WhatsApp account.
