If you have a knack of dropping your smartphone too often, the regular offerings in the market may not be good enough for you. Most of the current-generation high-end smartphones tend to be pretty sensitive towards regular falls and other such incidents. Such is certainly not the case with Handheld's recently-announced Nautiz X1, which is being touted as the world's toughest smartphone. There is definitely some credibility to this claim since Nautiz X1 meet the military standards when it comes to enduring high drops, extreme temperatures and humidity.
A number of other smartphones by other vendors meet a fairly decent toughness criterion.
