Samsung Galaxy S IV may have a more battery-friendly screen, floating touch. Specs ‘confirmed’ again

We’re exactly six days away from Samsung’s big event in New York, during which the Galaxy S IV will be officially unveiled. So, as you’d expect, we’re pretty much in ‘at least one rumor per day’ phase regarding Samsung’s next flagship device.

Today’s rumor talks about a new display technology supposedly used by the Korean giant for its handset. Samsung definitely loves its OLEDs for mobile devices, especially for flagships. Ever since it launched the original Galaxy S, a staple feature of all the phones in that line has been having an AMOLED touchscreen. But that may change, slightly.


Apparently Samsung will fit the Galaxy S IV with a ‘green PHOLED’ screen, similar to AMOLED in terms of image representation but different in that it should offer power savings of up to 25%, compared to, we assume, what an AMOLED Full HD screen would have had. And speaking of that, once again the fact that the Galaxy S IV will come with 1080p resolution is ‘confirmed’, if we can use that word for what is essentially an unverified rumor.

The biggest problem, in terms of battery consumption for AMOLED screens, is displaying the color white. In that scenario, they usually eat up more power than similar LCDs, despite the fact that they consume absolutely no power while displaying the color black. So, in ‘black-ish’ circumstances, an AMOLED screen offers great battery savings compared to an LCD. But almost the entire Web has pages with primarily white, or white-ish backgrounds, which means that Web browsing times on AMOLED devices are generally lower than on similalry specced phones with LCDs and identical battery capacities. Whether or not the ‘green PHOLED’ tech could help with this is unclear, but we’ll obviously find out soon enough.

Moving along, once again we hear about ‘floating touch’ support embedded in the Samsung Galaxy S IV (read: touchless gestures). This handset won’t be the first one on the market to come with such functionality (that honor belongs to the Sony Xperia Sola), but as it’s a flagship it may make this technology more well-known among average Joes. Whether or not it’s just a gimmick is still up for debate, of course.

All of the information above reportedly comes from ‘an insider’ who spoke to SamMobile. From the same source come some ‘confirmations’ for the Galaxy S IV’s specs, as well. We’re being told that the phone will pack an eight-core Samsung Exynos Octa processor, a 13 MP rear camera, 2 GB of RAM, and a Photosphere-like function called Samsung Orb. It will run Android 4.2.1 at launch, with an update to Android 4.2.2 promised to come in the same month as its release (a month which hasn’t been named, by the way). An enhanced version of Samsung’s TouchWiz Nature UX, perhaps the 2.0 iteration, will also be in.

Interestingly though, Samsung has two different prototypes for the Galaxy S IV, one comes with the aforementioned specs, while the other has a Qualcomm Snapdragon 600 processor and a Super LCD3 screen. It’s unclear which one will become the final product, or if they’ll both be sold, how that will go along. But so far we’ve heard that one model (probably the one with the Qualcomm CPU) will be destined for North America, while the other one will make its way to the rest of the world.

    Thanks for the scoop. It’s still an AMOLED screen but now adds green phosphorescent material along with the PHOLED technology both from Universal Display, Inc. Now that the green is added, the lower current drive should help with power consumption and heat.
