Here’s what I have found out so far on the interwebz and some of my thoughts on the features =P
-5-inch full high-definition Super Amoled screen, using Gorilla Glass 3, 441ppi , Pentile
-Google Android 4.2.2
-13MP rear camera, 2MP front camera
– eight-core Samsung Exynos in some countries , others use quad-core Snapdragon S4 Pro
– Plastic Chassis with metal bezel
Thoughts : Pentile again ?! -.- . Can’t they just go for true RGB .. 441 ppi is outstanding though. Plastic is used once again for its chassis, no surprise there.
Additional features :
Air Gesture –> Instead of touching the screen, the new S 4 has greater gesture controls. Users can skip through songs simply my moving their hands across the screen, or view contents of e-mail messages and photo albums by hovering their finger above the display screen. The Galaxy S 4 is able to sense the presence of your finger up to about a centimeter away from the display.
– New camera software allow users to remove a moving object completely from a photo, while another allow users to create a moving GIF file using multiple photos.
– Multiple Camera scenes
– A Camera function which allows user to be able to see front and rear views at the same time
Samsung Smart Scroll, which is designed to let users control the screen by where they look. You can scroll the browser or emails up and down without even touching the screen.
Samsung Smart Pause – For those watching videos, playback stops the moment a user’s eyes are taken of the screen, and will only resume when the user stares at the screen again.
S Translator – A built in translator in the device will translate foreign languages automatically in e-mail, text and chat messages.
Mobeam – a way to beam barcodes using pulses of infrared light
Group Play – Send music,documents to other phones. Ability to play music together at the same time. Seems to only work with other S4s -.- .
S Health –> S Health includes support for an integrated pedometer, temperature and humidity sensors in the SGS4. The S Health app is supposed to be able to track distance traveled and give you local identification of current temperature and humidity. The app also includes the ability to act as a meal tracker, just look up foods you’ve eaten and it’ll keep a running tally of calories consumed.
Air gestures is the feature which is pretty much innovative, the others doesn’t have the excitement factor. Samsung Smart Scroll is looking good too, but I read on some sites that both of these features work intermittently, so we shall see how it fares in the coming weeks when it is rolled out.
