If you are interested in the Samsung Galaxy Note 4, then ask yourself certainly the question of whether this smartphone is also waterproof, so survives contact with water without any technical damage.
Waterproof is described in most current smartphone with IP67 certification. With this certification, it is possible to use a smartphone for 30 minutes at a maximum depth of one meter under water without damage.
Unfortunately, the Samsung Galaxy Note 4 has not received this IP67 certification. This means that the Samsung Galaxy Note 4 is not waterproof.
Why Samsung has the Samsung Galaxy Note 4 the IP76 certification not missed is strange, because this is another argument for a new purchase for many smartphone users. It may be that for Samsung by the stylus, so the pen to write on the screen, not to ensure water resistance.
