There are rumors on the market that Samsung will launch two new variants of the existing Galaxy S5, a higher-end version called Galaxy S5 Prime and a lower one called S5 mini. GSMArena just leaked some information about these two new devices. The SM-G906, which will be the name of the S5 Prime will feature a 5.2 inch display at a QHD resolution- 2560x1440. The S5 mini will feature a 4.5 inch display at a 720p resolution. It seems that S5 Prime codename is KQ.
A couple of days ago there were rumors about a new Mega handset from Samsung. GSMArena leaked some news about this possible device also. The device's model number will be SM-G750 ( on an earlier post we supposed that this serial number will be the one for the S5 Neo, but as nothing is official we aren't that sure yet). Galaxy K will probably feature a 6 inch screen at a 720p resolution. The 6 inch screen it's right between the older versions of the Mega series; 5.8 and 6.3 inch. A thing is unclear, we are not sure if the next device from the Mega series will be shorter or bigger than the older devices, but probably in the next couple of days there will be some official information about it.
