iPhone 15 pro max, VERY BAD CAMERA QUALITY

I saved up money to buy the latest I phone which is I phone 15 pro max. I bought the phone at menlyn istore. It is my first time using apple product and I’m very disappointed. I regret and wanna go back to android. The camera Quality is so bad that I can’t even post my son’s pictures. They come out black like charcoal 😭. iphone did me dirty, with so much money I spent.
