If you hate the big camera bump of today's smartphones, you'll love the detachable lens of Xiaomi’s Modular Optical System.

I have made no secret about the fact camera bumps are getting too big. Some phones have been able to incorporate those bumps into quite smart designs, like the Xiaomi 15 Ultra but what if we could eliminate the bump altogether?

I tested the detachable camera concept and was even able to shoot some example images. Xiaomi may have been talking a lot about the cameras on its new 15 Ultra phone at this year's Mobile World Congress,
