Confirmed Killer Features of Samsung Galaxy S5 Prime, Certified in Korea

Every time Samsung releases a device meant a string of variants after. The Samsung Galaxy S5 flagship should not be any different. According to reports, Samsung has been preparing for the release of the Samsung Galaxy S5 Prime. While the device has been referred as Prime for its high end features, recent information also suggests that it may go as Samsung Galaxy F. Can Samsung deliver a killer handset?
Following the introduction of the Galaxy S5 flagship, JK Shin from Samsung denied reports about releasing a premium edition. According to Android Geeks, the Samsung executive may have refuted reports at that time to encourage Samsung Galaxy S5 sales. Admitting there is a premium variant coming may discourage users from purchasing the flagship and wait out instead for the Prime. This means fewer sales for the company. Likewise, there are also reports saying that the Samsung executive denied the information because Samsung has been working on a prime variant but not under the S5 series. The company may be working on a whole new premium product line.
Notorious tipster @evleaks has also leaked a photo showing the Samsung Galaxy F. According to the tipster, the Samsung Galaxy F product line will be released in an "Unpacked Ep. 2" event. The product line will reportedly replace the Samsung Galaxy S6 flagship.
If Samsung pushes through the product line, people can expect the following features:
- 5.3-inch Quad HD
- 2560 x 1440 resolution
- quad-core Snapdragon 805 SoC (reportedly the most powerful from Qualcomm yet)
Looking at the photo from @evleaks, people can see the device sports a metallic finish and thinner bezels. It will be hard to confirm if the device really has a metal build or it is just made of plastic with a metallic brush finish. Additionally, G for Games, reported about the three certifications (SM-G906S, SM-G906K, SM-G906L) related to the device. The certifications correspond to three South Korean networks: LG U+, KT and SKT.
