Sony is one of the most popular and first company that makes its whole flagship series water and dirt proof, while we are all amazed with that sort of protection that Sony gave to its flagship smartphones Z series (Xperia Z2, Xperis Z3, Xperia Z4... etc), the question that has never been asked is why making it waterproof ?
Making a smartphone device fully operational under water is a big deal, especially in the japanese market, the feature is not just used for just protection or premium-look but to Sony it has a whole different reason !
Apparently, the exclusive waterproof smartphone's existence is rooted in a peculiar user habit of Japan's female population! ...young japanese teenager girls, to be more precise. According to Panasonic executive "Taro Itakura", 90 to 95% of smartphones sold in Japan are waterproof because young Japanese women prefer to use their smartphones even while they are taking their showers! That's right your Sony Xperia or Sharp AQUOS smartphone are considered as a "must products" in Japan, possibly right next to soap, shampoo, and a trusty sponge all because that young japanese girls like to shower with them.
Can you really take a proper bath when your attention is preoccupied with the latest notifications and updates? We don't know, but we certainly cannot underestimate Japanese women!
