Xiaomi used live crabs and lobsters to test the toughness of its Mi 4 smartphone

Xiaomi recently posted a video on Facebook showing how its Mi 4 smartphone passed an unusual toughness test.

The company used live crabs (a freshwater crab, and a Japanese blue crab), as well as a lobster against the Mi 4. As you may know, the Xiaomi Mi 4 is a well-made handset that's built around a stainless steel frame, so it's not surprising that crab and lobster claws can't damage it - as the video, embedded below, is showing. Sure, the lobster's claws are quite powerful, being capable of breaking glass, but we're talking about metal here after all.

Naturally, the video caused controversy, as some commentators pointed out that Xiaomi should not use animal testing (because that's what this is, after all) to promote its handset.
