My iPhone 16 Camera Freezes and Shows Green Screen in WhatsApp After 2 Months

I bought an iPhone 16 around two months ago, and I’ve already started experiencing a frustrating camera issue. Whenever I try to open the camera in WhatsApp, a green warning screen appears. Even when I open the regular camera app, it either freezes or lags badly.

Restarting the phone doesn’t solve the problem. It keeps happening, and it’s affecting basic usage of the phone—especially for someone who uses the camera frequently. For such an expensive and premium device, this kind of issue should not be happening within the first two months of use.
