7 Best Fixes for Black Screen During WhatsApp Video Call On iPhone

You can use WhatsApp connect with your family and friends over text and audio or video calls. To make texts more interactive, you can even react to WhatsApp messages with different emojis. However, nothing can come close to a good, old video call over WhatsApp.

Some users have reported the issue of a black screen while switching from audio to video call or switching between apps during a WhatsApp video call. The only resort for them is to disconnect and start the video call again. If you are also facing the same, here is a list of solutions to fix this issue.

1. Switch From Mobile Data to Wi-Fi

Let us start with the basic solutions. The first one is that you should switch from Mobile Data to Wi-Fi. The strength of mobile data depends on your location. You might be getting good connectivity for calls. But that might not be the case for mobile data speed as well. Plus a lot of users have daily data limits. It is recommended that you connect your iPhone with Wi-Fi and then make the WhatsApp video call.

2. Check Your Internet Speed

After switching to Wi-Fi network, check your internet speed. Your Internet Service Provider might be facing some downtime or undertaking maintenance work in your area. Whenever that happens, you internet connectivity will be spoty and WhatsApp Video Calls will show black screen randomly.

3. Switch to a 5GHz Frequency Band

A 5GHz frequency band provides faster speeds compared to a 2.4GHz frequency band on your Wi-Fi network. So switching to the 5GHz band can significantly improve your WhatsApp video call quality and stop the black screen issue. However, you don’t go too far away from your router due to area restrictions with a 5GHz network. Refer to our guide to boost the router’s Wi-Fi signal.

4. Check If WhatsApp Has Camera Access Permissions

After installing a software update, or to prevent accidental video calls, you might have revoked the camera access for WhatsApp. Whether that transpired or not, it’s a good idea to check whether WhatsApp has camera access to conduct video calls. Follow these steps.

Step 1: Open the Settings app on your iPhone.

Step 2: Scroll down and tap on WhatsApp.

Step 3: Check whether the toggle for ‘Camera’ is active. If the access is already enabled, tap the toggle to turn off, wait a few seconds, and turn it on again.

Close the Settings app and open WhatsApp to start a video call to check if the problem persists.

 

5. Disable Less Data Usage for WhatsApp Calls

WhatsApp gives you the feature of using less data for audio and video calls. This is helpful if you are using a mobile data plan with a humble usage limit. However, this option might act as a hindrance during WhatsApp video calls and show a black screen. You can try turning off this feature, especially when you’re using Wi-Fi to make video calls. Follow these steps.

Step 1: Open the WhatsApp on your iPhone.

Step 2: Tap the Settings icon at the bottom-right corner.

Step 3: From the following screen, Select Storage and Data.

Step 4: Tap the toggle to disable the option of ‘Use Less Data for Calls.’

Start a video call in WhatsApp and check if you or the other person still witnesses a black screen.
