Introducing the Kyocera Digno rafre: With Soap Resistance and a Self-Healing Case for New Levels of Durability


Smartphones have become an indispensable tool for staying connected to business, family and friends, carried at virtually every moment of every day. But much like life itself, phones can get a little messy. We eat and sleep with our smartphones, and we take them with us everywhere, save for bathing. With the latest addition to the Kyocera smartphone family, the Digno Rafre, announced on December 3 and available in Japan, water and soap resistance means that even the bath no longer has to be a “no-phone zone.” And with the new self-healing case found on the Digno Rafre, even more environments become phone-friendly.

At Kyocera, we build rugged smartphones not only for survivability, but also with cosmetic durability and usability in mind and the Digno Rafre is the perfect example of how we do this. It features built-in resistance to hot water, allowing the phone to be used while washing hands or bathing. And since the backside of the device is coated with a “scratch-healing” material that self-heals minor abrasions, the Digno Rafre can avoid the nicks and scratches that make normal smartphones look shabby soon after purchase.

Hot Water & Soap Resistance – makes your phone easier to clean!

Soapy water cleans by lowering water surface tension. While this is great for hands, it is not so good for regular smartphones. However, the Digno Rafre goes beyond water resistance and adds on a resistance to the effects of soap as well, passing all of Kyocera’s propriety tests so that the smartphone can be used with foaming hand soap.

In addition to conventional waterproof performance, the Digno Rafre also features resistance to hot water. The new smartphone is equipped with a touch-panel display that can be operated while either the screen or the user’s hands are wet, such as conditions of heavy rain or while the users is doing the dishes.

Kyocera also takes waterproofing beyond just survivability. Sure, the phone can get wet and survive, but who wants to wait for the phone to dry before it can be operated? Most touchscreens used in mobile devices sense wetness as “touches,” making it virtually impossible to actually navigate and use the phone while the display is wet. Like many of Kyocera’s durable, waterproof devices, the Digno rafre takes waterproofing one step further by adding Wet Touchscreen Operation, a feature that allows it to be operated while either the screen or the user’s hands are wet. Who hasn’t received an important call while washing their hands? And who thinks it’s okay to be “off the grid” any time there’s some rain? Wet Touchscreen Operation gives users not only the peace of mind that their Kyocera phones can get wet, but also that water doesn’t mean a pause in staying connected and productive.

Scratch Self-Healing

The coating on the Digno rafre allows minor abrasions caused in everyday life to self-heal. Applied to the rear housing of the smartphone, this dynamic material helps Digno rafre to maintain its cosmetic appeal and pristine condition long after purchase and through typical wear and tear.


Enhanced Durability

With a scratch-resistant, high-strength Dragontrail® X glass display, combined with a slightly recessed screen, the Digno rafre offers additional protection against screen damage caused by accidental drops. With vibration resistance for passengers on bicycles and motorbikes and low-temperature resistance for use in extreme environments, winter-sports athletes in Japan may have found their ideal match.


At Kyocera, features like soap-resistance, Wet Touchscreen Operation and self-healing cases are just the latest in our efforts to make mobile devices that will not only survive worst-case scenarios, but also thrive in them, keeping users connected and online – all while looking good doing it.
