Apple iPhone XS user review

Has anyone had any issues with the XS max. Mine is flickering, losing pictures , today I was trying to attach photos to an email and it kept shutting down the email and going to the home screen, I lose sound from time to time, my books app wasn’t working I had to do a full system reboot but yesterday I’ve noticed it’s playing up again. Can anyone help or has anyone had similar issues. This is by far the worst model I have owned from Apple. I’m seriously thinking it’s a complete dud. I’m so frustrated by this phone and Apple just handball me when I try to contact them the last time it took 4 days of constant phone calls at work to get to someone to help me I can’t do that each time there is an issue and there’s plenty with this model
