Fans have been clamoring for Samsung Electronics Co., Ltd. (LON:BC94) (KRX:005930) to grant their wish of a metal backing for the Galaxy S5, but it doesn’t sound like that will happen. There could be some other things to look forward to, however, including a display with the highest resolution of any other smartphone, according to Slash Gear.

Galaxy S5 expected at CES

Several sources recently have suggested that Samsung will unveil the Galaxy S5 at the 2014 Consumer Electronics Show. Of course the Korean company has not confirmed this, and in the past, it has planned its own events instead of revealing handsets at trade shows.

Galaxy S5 could feature a 2K screen

According to Slash Gear, the Galaxy S5 could be the most revolutionary upgrade of a handset in a long time. The site says the main attraction could be the rumored 2K screen. You may have heard a lot of talk lately about 4K ultra-HD in video streaming and smart televisions. The reason 2K technology would be such a big deal is because it packs beautiful graphics into a much smaller package than previously was possible.

A 2K screen has a resolution of 1440 by 2560. Putting it into a 5-inch or 5.2-inch display would make the pixel density “well beyond even the sharpest smartphones on the market today,” according to Slash Gear. The density would end up being more than 560 pixels per square inch. Samsung revealed plans for a 2K screen at its Analyst Day.

Other things to look forward to in the Galaxy S5

Another thing we could expect in the Galaxy S5 is an ISOCELL camera, which was also talked about at Samsung Electronics Co., Ltd. (LON:BC94) (KRX:005930)’s Analyst Day. This would be a nice upgrade to the Galaxy camera, which Samsung has received much acclaim for in the past.

Eye-tracking technology could also receive improvements, and Samsung may even be adding eye-scanning capabilities for better security. It’s also possible that in addition to the Galaxy S5 itself, there will also be a Galaxy S5 Active, which would be aimed at people who need features like dust proofing and water proofing because they tend to be more active than others.

What about a metal casing for the Galaxy S5?

And finally, will Samsung ever deliver on a metal backing for the Galaxy smartphone line? On Wednesday we heard a rumor suggesting the final word on the issue. DigiTimes reported that Samsung decided metal was too expensive and that it didn’t need to do a metal backing because its plastic-backed phones were already immensely popular.
