I came into hype and purchased S21 to experience Samsung's Flagship and to experience their very famous One UI.
Today I updated the April security patch & after that I'm not able to do any video call via WhatsApp and Snapchat, jittering was not a surprise in earlier times too but now it's more friendly.
Please fix it ASAP, I'm not at all happy and regretting my decision to take this over iPhone.
Thank you for sharing your concern. And please follow the easy troubleshooting steps which might help to solve the issue.
Clearing the app cache is kind of like a cleanse for your apps. It will get rid of residual files that could be slowing down the app. Open Settings, and then swipe to and tap Apps. Select or search for the app you want to clear. Tap Storage, and then tap Clear cache.
However, we would request you to register your concern in Samsung Members Application. So, that our concern team gets back to you as soon as possible.
