7 Best Fixes for Black Screen on WhatsApp Video Call on iPhone

You can use WhatsApp to connect with your family and friends through 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 on WhatsApp.

Some users have report the problem of a black screen when switching from an audio call to a video call or when switching between applications during a WhatsApp video call. The only recourse for them is to disconnect and start the video call again. If you are also facing the same problem, here is a list of solutions to fix this problem.

1. Switch from mobile data to Wi-Fi

Let’s start with the basic solutions. The first is that you need to switch from mobile data to Wi-Fi. The strength of mobile data depends on your location. You may be getting good connectivity for calls. But that may not be the case for mobile data speed either. Additionally, many users have daily data limits. It is recommended to connect your iPhone to 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 ISP may be experiencing downtime or undertaking maintenance work in your area. Whenever this happens, your internet connectivity will be spotty and WhatsApp video calls will randomly show a black screen.

3. Switch to a 5 GHz frequency band

A 5 GHz frequency band offers faster speeds compared to a 2.4 GHz frequency band on your Wi-Fi network. So switching to the 5 GHz band can significantly improve the quality of your WhatsApp video calls and stop the black screen problem. However, you don’t stray too far from your router due to area restrictions with a 5 GHz network. Check out our guide to boosting the router’s Wi-Fi signal.

4. Check if WhatsApp has permissions to access the camera

After installing a software update or to prevent accidental video calls, you may have revoked camera access for WhatsApp. Whether this happened or not, it is a good idea to check if WhatsApp has access to the camera to make video calls. Follow these steps.

Step 1: Open the Settings app on your iPhone.

2nd step: Scroll down and tap WhatsApp.

Step 3: Check if the toggle for ‘Camera’ is active. If access is already enabled, tap the toggle to disable, wait a few seconds, and then re-enable it.

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 option to use less data for audio and video calls. This is useful if you are using a mobile data plan with a modest usage limit. However, this option can act as a hindrance during WhatsApp video calls and show a black screen. You can try disabling this feature especially when using Wi-Fi to make video calls.
