What Makes the UMIDIGI S2 Pro Water Resistant? Let’s find out!


A couple days back, Chinese phone maker – UMIDIGI – has released an unboxing video of their latest UMIDIGI S2 Pro that portrays the phone surviving being submerged into water. You can check the video down below, after that we’ll be learning how they achieved it!


The process UMIDIGI used to make the S2 Pro waterproof is called “multifunctional nano-coating protection”, which is the same that we can see on Huawei devices.

The schematic diagram above shows the creation process of the nano-polymer film. In a vacuum plasma machine, the active surface of the products and the broken end of the molecular chain of the chemical reagent causes polymerization, which forms one or more layers of nano-polymer protection film.

This nano-polymer protection film is waterproof, moistureproof and anti-corrosive. With its help even the phone’s motherboard could be exposed to water and still work just fine. UMIDIGI say that even if your phone gets soaked and stops working, you can dry it up with an hair dryer and it should be back to full working order.

Albeit the UMIDIGI S2 Pro is splash, water, dust resistant and was tested under controlled laboratory conditions, it doesn’t mean these results will always be true. Over time the nano-polymer layer might wear off and cause irreversible damage. Thus try to keep it dry as much as possible and don’t dump it into water to test it out. What’s more UMIDIGI does not cover water/liquid damage under warranty.
