My Iphone's Camera Error

Hello apple support team.
Sorry my english is not good so i have to use google translate.


In March 2021, I bought an Iphone 12 Pro Max in Pacific Blue color from an authorized Apple dealer in Vietnam.
but after using it for more than a month, I encountered a camera problem.Specifically, when I use the iPhone's default camera, after pressing the button to take a photo, it is exited to the home screen.
And I can't use iPhone camera and other camera related apps. To use the camera, I had to restart the device but this situation only lasted 15 days and then the error continued. I took it to an authorized Apple service center for repair, here Apple Care in Vietnam provided me with a new phone, but this phone only after 15 days continues to have this error. After that, I asked the place that sold the phone for me to help me upgrade to Iphone 13 pro max, but as of today it is 14 days since I used this phone, this situation continues, same error is not using the camera after only a short period of time, 15 days to be exact. I'm very sad, I have been using Android operating system for a long time, but when I switched to IOS Iphone 12 Pro max it crashed, now I use Iphone 13 pro max, also error. I am really haunted by this. I spent a large amount of money, equal to 2 3 months' salary of Vietnamese people, to own it, but got the results I didn't want.


The video describes the error of my phone's camera, old and new, both phones have the same error.
