We don't always think about it but there are items we use on a daily basis that contain more germs than a public toilet. These are unsuspected smartphones that, during the day, we often use with dirty hands or in outdoor environments that are not exactly clean.
In Japan they decided to solve the problem by creating the first washable smartphone. It's called Digno Rafre and was created by the Japanese company Kyocera Telecom. The phone is completely waterproof: to achieve this there are no speakers but the sound is transmitted through the vibrations of the screen.
This smartphone seems to be very resistant even to falls, in fact it is sold with a floating rubber support in the shape of a duck: ideal for use in the bathtub!
To wash the Digno Rafre, the company recommends cleaning your hands first, then using the foam obtained on the phone, rubbing it. Finally rinse everything under running water. The cost is ¥ 57,420 (around € 500), however it will be difficult to see it in the European market as Kyocera has no plans to sell outside of Japan.
