A while back we caught wind of a possible Samsung Galaxy S5 variant with a blisteringly hi-res Quad HD screen and now it’s appeared again. This time around the mystery handset, currently known as the Galaxy S5 Prime, has been listed on Indian import site Zauba. The site lists four ‘SM-G906K’ units as having been shipped from South Korea for “R&D purpose.” This is the same Galaxy S5 ‘Plus’ that’s been mooted for a while.
