I’ve been experiencing the exact same issue since I purchased my iPhone 16 Pro on launch day in September, and it has not been fixed despite all the iOS updates I’ve installed. I have an open case with Apple Support, but every time I call for an update, a new supervisor takes over and tells me the same thing: that this is a software issue. We’ve tried everything—factory resets (twice), network and general settings resets multiple times, collecting logs, sending screenshots and videos, verifying all app settings, making sure DND isn’t interfering, and countless other troubleshooting steps. Nothing has worked. I’ve asked for a replacement, but they refuse, claiming it’s not a hardware issue. However, given how many people are reporting this, I can’t help but feel that this is an inherent hardware flaw in some iPhone 16 models. The fact that Apple keeps pushing updates without fixing it is frustrating. I just wanted to share my experience in case a developer sees this and can actually help us.
