Fresh rumors about Samsung's Galaxy S4 hint at battery-saving screen technology and floating touch input for the upcoming flagship Android phone.
According to SamMobile, an inside source says that the Galaxy S4 will use a new kind of AMOLED display called "green PHOLED," which relies on phosphorescent organic light-emitting diodes, hence the acronym.
PHOLED uses phosphorescence instead of fluorescent light like traditional OLED displays, making it significantly more energy efficient. According to SamMobile, PHOLED displays are 25 percent better at consuming power, meaning less battery drain.
The technology has so far been implemented in displays that use PHOLED for one or two of the red, green or blue light spectrums. PHOLED would cover the green-yellow spectrum, lowering the display's power needs.
While we like the thought of a more energy efficient phone, there are also hints that users will touch the screen a whole lot less.
The same inside source indicated that Samsung will use floating touch technology in the S4, letting users hover their finger over the screen to perform actions like previewing emails and thumbnails without tapping to open them.
Samsung included similar technology in the Galaxy Note 2, which used the S Pen to hover over the screen for the Air View feature.
A little factoid: You may remember Sony's Xperia Sola featured floating touch.
Floating touch would join eye control through the Smart screen suite as a rumored new interface for the Galaxy S4.
SamMobile's source may be throwing us for a loop, so don't take the above rumors are hard and fast fact.
Samsung will reveal all during next week's Unpacked event, and TechRadar will be there to bring you all the details on Samsung's new flagship smartphone.
