What to expect from Samsung Galaxy S4

A series of images published on a Chinese forum for Samsung fans shows a smartphone that users claim is the new Galaxy S4. The handset appears slightly larger than the S3 and The Verge, which picked up the photos, says the forum claims the phone has a 1080p display, runs Android 4.2.1, has a 1.8GHz Universal5410 processor and 2GB of RAM.

5-inch HD screen
There’s no fighting the trend: Phones keep getting bigger and so is the Galaxy S4. A 4.99-inch Super AMOLED 1080p screen was spotted at CES, and tech watchers believe it's the screen for the new S4. That means the phone would have a resolution of 1,080 x 1,920 with 440 pixels per inch (PPI), up from the S3, which is already a substantial 4.8-inches. But bigger is better, right?

Here comes Jelly Bean
The S4 will be running Android 4.2. Code-named Jelly Bean, the latest update to Google’s mobile operating system promises a brand new camera experience and a novel new way to type.

An eight-core processor?
It’s possible that Samsung will equip its new flagship with its powerful Exynos 5 Octa eight-core processor, making the S4 one of the most powerful phones on the planet, but the company might save it for the Note III. Instead, recently leaked photos seem to indicate a quad-core processor running at 1.8 GHz, up from the 1.4-GHz chip in the S3.

13-megapixels by 2.2 megapixels
There aren’t too many details about the camera, but most reports indicate a 13-megapixel camera accompanied by a 2.2. megapixel front-facing camera.

Networked beast
4G LTE and 802.11 ac -- a faster Wi-Fi specification -- make sure the S4 keeps up the pace.

Eyetracking?
Perhaps the most exciting rumors is the prospect of eye-tracking technology that will enable the phone to detect when you are finished reading a page and automatically scroll for you, according to a New York Times report. It will even pause your video when you look away.

Still plastic
A big complaint against the Galaxy SIII was that its plastic materials felt cheap and lacked the heft of the iPhone’s sleek aluminum unibody. But fans hoping for a switch to metal are out of luck. Samsung is sticking with plastic citing the need to balance aesthetics with durability and manufacturability.

Wireless charging capabilities
The Galaxy S4 will have the ability to charge its 2,600-mAh battery wirelessly with an optional dock,
