WhatsApp video call freezes, green/purple screen

I don't know if I fixed this issue, after last night and this morning trying different things, I think I did it. The first idea was about the update of WhatsApp from version 2.26.25.73 which was since last Saturday to the new update yesterday 2.26.25.74. I updated WhatsApp, my mom's phone did it automatic last night, Today, with my sister we tried and the problem was there. We were using our IiPhones, then we tried calling her from my Android tablet and everything was perfect. So we assume the problem was the communication between iPhones, maybe the last iPhone update. But curiosity was stronger; I was checking things on WhatsApp on my iPhone, comparing with WhatsApp on my Android. And… tatata (drums please) there is one option in WhatsApp iPhone: "Settings", "Storage and Data," "Use less data for calls" . it was unselected. I selected it (switch on green), and I did the same on my mom's iPhone. I video- called her and ... (drums again) we spoke for three minutes and no colours, no freezing scream. Yesterday, just at the beginning, the problem was there. I'm waiting to share this with my sister (must be tomorrow) and see if it also works with her. The explanation is long to write, but it works with my mom. Hope you find this info useful.

You may try some of these steps. Please check after each step...

1. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
2. If you're using a VPN, disable it and check if the error goes away. Go to Settings > General > VPN & Device Management and turn off any active VPNs. Disabling a VPN only from the iPhone settings may not completely turn it off. To fully disable it, you need to switch it off from the VPN service provider’s app or remove the configuration profile they installed. Only then is the VPN truly off, which can help if it’s causing issues with cellular or Wi-Fi connectivity. If your device has network connectivity issues, check for ...
3. Reset Network Settings: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings: Only network settings are removed.
   1. When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
   2. To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.
   3. To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
   4. Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
   5. 
4. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
   4. 
5. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.

I fixed mine by deleting the app completely after doing a backup save

restarted my phone, downloaded WhatsApp and no issues since!! :)
