With billions of iPhones sold, you might think we know everything about Apple's smartphone. But people are still just noticing a quirky 'optical illusion' in the phone's design. It's there on most iPhones since iPhone 7, but have you spotted it?
I think that describing it as an optical illusion is actually a little generous. It's basically just a redundant design feature that's used to make the phone look more symmetrical, but its still causing surprise (see our guide to the best iPhone 14 prices if you need to upgrade).
