We are undeniably reliant on our smart-devices and many know the pain of spilling a mug of coffee onto a phone and never seeing the little screen light up again.

One firm making waves here at MWC14 has developed a process called nanocoating which will protect any device from water or dirt.

As part of P2i's display at MWC, a stopwatch is set on a smartphone and the phone is thrown into a tank of water. Passers by can see the minutes tick by, with the phone working well after 35 minutes.

P2i are working with a number of phone manufacturers at present to apply this protection onto various device. Watch here for more information on how it works:
