What's the difference between that and say, changing your brake rotors and brake pads? There's a level of danger there if it's not a professional doing it.
It's frankly one of the reasons I got rid of my iPhone 6S shortly after buying it, for another Android phone. A lot of Apple's ergonomic choices just seemed bizarre to me compared to most Android devices. I'm sure they've gotten better since, but things like the fingerprint reader on the front were in my opinion bizarre and made me have to completely hold the phone different just for my fingerprint, where on most Android phones my finger is already right there in its normal usage position in my hand.
