Mobile phone failure, the water short circuit caused by the problem, has been a large proportion, so now more and more attention to these details of mobile phone manufacturers.

Sony is the world's first mobile phone company to do three mobile phone company, but three anti-level IPX67 above the level of waterproof and dustproof, and later Samsung, Apple, Huawei, millet and other companies to join the phone waterproof and dustproof team.

In the phone waterproof performance, Samsung started to be much earlier than Apple's.
