Master leaker evleaks was able to grab a screenshot of the Samsung website before the image was taken down. With the inclusion of the Samsung Gear and the Gear Fit on the website, it surely looks like the Korean based tech titan is planning on marketing the Galaxy S5 mini Dx with these wearable accessories.
Evleaks also tweeted a rather low-resolution picture of the 4.5 inch Galaxy S5 Dx all by its lonesome. The phone will get to share the IP67 certification of the full-sized Samsung Galaxy S5. That means that the device can be submerged in up to 3.2 feet of water for as long as 30 minutes, without sustaining any damage.
