With the announcement of the release of Samsung Galaxy S4 comes a bunch of rumors as well. What folds now primarily pertains to the screen of the device. According the rumors surging around Samsung Galaxy S4 will be equipped with floating touch technology. Floating touch technology allows you to interact with the device by hovering your finger above the screen. It works with the help of electrical field created by our finger which is then detected with the help of a sensor, pretty much similar to what you have seen in Samsung Galaxy Note II where you use S pen to interact with notifications and emails. Same goes for the Sony’s low end phone Xperia Sola.
Previously the device had AMOLED display but now the S4 is rumored to have Green PHOLED. So, what’s the difference? In AMOLED screen the green and blue OLEDs were fluorescent where red OLEDs were phosphorescent. But now the S4 is touted to be equipped with green and red OLEDs with phosphorescent materials and fluorescent materials for the blue ones. It does not augment the picture quality or so but it does aids in the power efficiency of the device, almost 25% more power efficient.
It is also believed that Samsung is preparing two prototypes of S4. One with the LCD display and runs on Qualcomm Snapdragon 600 processor whereas the other one is said to have an AMOLED display and uses Samsung Exynos 5 Octa processor. As for now there is no clue whether Samsung will sell both of the devices or drop any of the two before its introduction next week in New York.
And lastly, the device will run on Jelly Bean Android 4.2.1 at the time of its launch but will be upgraded to 4.2.2 as soon as the update hits in the same month.
