iPhone 18 Pro Max powers off when I double click to pay with Apple Pay

While using three day old iPhone 18 Pro Max it powers off when I double click to pay with Apple Pay. I mean OFF as in hold the power button and having to wait 5-10 minutes before it turns back on. It's NOT overheating while charging but it gets hot while browsing on Safari or Google Chrome mobile browsers.

A day and a half before this happened I was getting severe screen la and flickering and the screen would dim and get bright and dim and I have have Auto Brightness off. I'm thinking hardware and not software at this point.

IF this has happened to you please let me know.

Apple support said there was nobody complaining about the issues I'm having but I've seen several posts about the screen lag.

I’ve had the same issue, it’s happened multiple times where I tap to pay and my phone shuts off completely. It happens when I don’t double click fast enough to use Face ID.

You have fourteen days from your purchase date to exchange your iPhone.

If you adjusted any settings in Accessibility? It’s possible to disable double clicking the side button by enabling certain Touch settings.

Mine is 6 days old, has shut off twice when using Apple Pay the past 2 days. Turns off after double clicking the power button requiring a restart.

When I double click to initiate Apple Pay authentication, both clicks are performed in less than a second. How fast or slow are you double clicking?
