How to fix the Viber camera when it is not working

Start with the camera test at the top of this page. If your picture appears here, the camera works and Viber needs permission or the right camera selected. That one check tells you whether to fix Viber or the device itself, and saves you from trying fixes that cannot help.

Quick checks first

  • On a computer, Viber Desktop must be linked to Viber on your phone before video calls work.
  • Update Viber on every device; desktop and mobile versions must be reasonably recent to call each other.
  • Close other apps that may hold the camera, then restart Viber.

Viber camera not working on Windows

  1. In Viber Desktop, open Settings › Audio & Video and choose your camera from the video list; the preview shows whether it works.
  2. Open Settings › Privacy & security › Camera (on Windows 10: Settings › Privacy › Camera). Turn on Camera access and Let apps access your camera, then check that Viber is allowed in the list. Programs installed from the web appear under Let desktop apps access your camera, which must also be on.
  3. If the preview stays black, close Viber completely from the system tray (right-click the icon › Quit), unplug and reconnect an external webcam, and start Viber again.
  4. If no app can use the camera, check the driver with the Windows camera guide on this site.

Viber camera not working on Mac

  1. Open Apple menu › System Settings › Privacy & Security › Camera and turn on Viber. Quit and reopen Viber afterwards. On macOS Monterey and earlier the switch is in System Preferences › Security & Privacy › Privacy › Camera.
  2. In Viber Desktop, open Settings › Audio & Video and select the camera you want.
  3. Quit Viber with Cmd+Q and reopen it after changing permissions.

Viber camera not working on iPhone

  1. On your iPhone, open Settings › Apps › Viber (on iOS 17 and earlier: Settings › Viber) and turn on Camera. If Camera is missing from that screen, Viber has never asked for access: start a video call once and tap Allow.
  2. Make sure Camera is allowed in Screen Time restrictions, then force-close and reopen Viber.

Viber camera not working on iPad

  1. On your iPad, open Settings › Apps › Viber (on iOS 17 and earlier: Settings › Viber) and turn on Camera. If Camera is missing from that screen, Viber has never asked for access: start a video call once and tap Allow.
  2. Keep Viber full screen during calls and restart the iPad if the camera stays black.

Viber camera not working on Android

  1. Open Settings › Apps › Viber › Permissions › Camera and choose Allow only while using the app. On Android 12 and later, also swipe down twice and make sure the Camera access tile in Quick Settings is not turned off.
  2. Clear the cache in Settings › Apps › Viber › Storage & cache.
  3. Set battery usage for Viber to Unrestricted so calls are not cut when the phone saves power.
