I am on my third iPhone 16 Pro Max. All with identical behavior. I have been able to demonstrate it to genius bar and they have not known what to do other than give me a new phone. I am now working with Apple support and I am working with a senior advisor and doing things like sending log files and videos of the behavior. I just sent a batch of log files yesterday and I'm waiting to hear back.
My suggestion is for you to call. Apple support and ask for a senior advisor and offer to send a video of the behavior and log files. Don't let them tell you it's not a problem because it is. If you do this, it will reinforce the fact that they have a problem to deal with.
I can give you a case number to reference if you need it, but if you ask them to search their knowledge base they should come up with something acknowledging they are dealing with an issue.
Good luck
