This would put the release in the same time frame as the LG G3 which is going to be unveiled towards the end of May. LG has already sent out invites for that event. On the other hand Samsung is still quiet about its ambitions of tackling the smartphone that’s also referred to these days as the “Galaxy S5 killer.”
Galaxy S5 Prime is rumored to have a premium design, presumably it may be fashioned out of metal. It is expected to have top level specifications with a 2K display being one of its defining features. We already know that the LG G3 will have a 2K display so both smartphones will certainly be neck and neck in that department.
However the report claims that Samsung initially wanted to put the 2K display in Galaxy S5 but it didn’t do that due to high cost. Apparently it costs more to produce a Super AMOLED 1,440×2,560 pixel resolution display than it does to produce one with the same resolution on the LCD technology, which LG is using for its G3.
Since the Galaxy S5 Prime will also have a higher cost the report claims it wouldn’t fly off the shelves like the Galaxy S5. Thus it would be easier for Samsung to keep production in check and avoid any supply/demand issues. It should be kept in mind though that none of this has been officially confirmed so best take it with a grain of salt.
