What to do if the screen goes black when calling on WhatsApp - in detail?
When the screen goes black during a WhatsApp call, it can be frustrating and confusing. However, there are several steps you can take to troubleshoot the issue:
-
Check Your Internet Connection: A poor or unstable internet connection is often the cause of call issues. Ensure that your Wi-Fi or mobile data connection is strong. You can try switching between different networks to see if the problem persists.
-
Restart WhatsApp: Sometimes, simply closing and reopening the app can resolve temporary glitches. Close the app completely from the recent apps menu and then open it again.
-
Update WhatsApp: Make sure you are using the latest version of WhatsApp. Outdated versions may have bugs that cause issues like black screens during calls. Check for updates in your device’s app store.
-
Clear Cache and Data: Clearing the cache and data for WhatsApp can help eliminate any corrupted files that might be causing the issue. Go to your device settings, find WhatsApp under Apps or Application Manager, and clear the cache and data. Note that this will log you out of WhatsApp, so you’ll need to sign back in.
-
Check for Software Updates: Ensure your phone's operating system is up to date. Sometimes, compatibility issues between the OS and the app can cause problems. Go to your device settings and check for any available software updates.
-
Disable Power-Saving Mode: Power-saving modes can sometimes interfere with app functionality. Try disabling this mode temporarily to see if it resolves the issue.
-
Check Battery Optimization Settings: Some devices have battery optimization settings that can restrict background data usage for certain apps. Go to your device’s battery settings and make sure WhatsApp is not restricted.
-
Reinstall WhatsApp: If none of the above steps work, try uninstalling WhatsApp and then reinstalling it from the app store. This can help resolve any underlying issues with the app installation.
-
Check for Hardware Issues: In some cases, the problem might not be with the software but with the hardware itself. Ensure that your phone's screen is functioning properly and that there are no physical obstructions or damage to the device.
-
Contact WhatsApp Support: If you’ve tried all of the above steps and are still experiencing issues, it may be time to reach out to WhatsApp support for further assistance. They can provide more specific guidance tailored to your particular situation.
By following these steps, you should be able to diagnose and potentially resolve the issue of a black screen during WhatsApp calls.
