I have an iPhone 10s Max. I keep it in a protective case. Recently, as I was stepping from the car, I dropped my phone to the concrete driveway (about an 18 inch drop) and then I picked it up and continued my day. I never even considered the possibility that the back glass would crack as the drop (and the impact) was so minimal, but when I removed the phone from the case two days later I saw where glass on the rear bottom corner was cracked. I couldn't believe it. But then it got worse; I learned from Apple that the cost to replace the glass was 599.00 dollars! This makes no sense and this type of situation really isn't fair to the iPhone buyer who tried to protect their phone. This is where Apple really gets to me with building such a tender-ass phone and making the owner of such a phone pay through the nose to repair/replace it. I love Apple products but I'm not sure what to do about this. Right now I just use it with the case on, knowing that my phone is all but worthless.
