Earlier this month, the Galaxy S7 Active failed Consumer Reports’ dunk test twice, despite the fact that its advertised as being water resistant. Samsung originally said that it “stands behind” the GS7 Active’s water resistance rating, but it turns out that there was an issue with the phones.

Samsung has revealed that it found a manufacturing problem that caused some Galaxy S7 Active phones to not stand up to water as well as they should’ve. The manufacturing problems have been corrected, Samsung says, and Samsung PR manager Philip Berne added that the number of GS7 Active units that’ve been returned due to water damage is “tiny” compared to the total number of units sold.

If you have a Galaxy S7 Active that ends up getting damaged by water, Berne says that you can utilize the phone’s one-year warranty and return your phone to the retailer that you bought it from or to Samsung itself and get a replacement.

The water resistance feature of the Galaxy S7 Active is one of its highlight features, so it’s good that Samsung was able to quickly identify the manufacturing issue and correct it. And while you probably shouldn’t just go submerge your GS7 Active in water to see if it’s one of the affected units, at least you now know that if the phone does fail after going for a dive, you can get a replacement.
