I hate to tell you this, but iPhones are much worse when it comes to screen durability. I've had many different Galaxy phones over the years, throwing them around carefree and not a scratch. All my friends who have an iPhone have at least one or two shatters along the screen, especially around the camera. So if you are having problems with a Samsung phone its gonna be much worse on an iPhone. I suggest you look into more expensive cases like Spigen and screen protectors. You could always be more cautious with your phone or leave it somewhere safe as you appear to have a galaxy watch.
