Official teaser hints at Samsung Galaxy S7 water resistance
To us, this seems almost definitive proof that the Samsung Galaxy S7 and Galaxy S7 edge will offer resistance against the elements. Note that this wouldn't be an entirely new feature for the Samsung Galaxy S series: the Galaxy S5 came with IP67-certified dust and water resistance.
Last year when Samsung introduced a new glass-and-metal sandwich design for the Galaxy S6, the manufacturer dropped the feature, but it looks like water/dust resistance is making a comeback with the upcoming Galaxy S7.
Speaking of comebacks, a recent leak appears to confirm that the Galaxy S7 will bring back microSD card support, a feature that many missed on the Galaxy S6, but which has been available on all of the previous Galaxy S smartphones.
