Issues with iPhone 12 Pro Max

Hi team, I recently purchased a brand new iPhone 12 Pro Max. It takes about 10 secs to open the camera or Snapchat so I miss out on amazing pictures. It also has a delay of about 5-6 secs of sounds. So I will turn off the screen and a few seconds after the sounds will finally come. It’s very strange. If I’ve been using the camera sometimes it will start straight away but 95% of the time there is a massive delay. When I scan for example using the COV1D app it is a massive delay as well.

I have it all up to date and done all the normal suggestions.
