The Galaxy S4 release date is nearly here, and as the big announcement closes in, journalists and technology experts around the globe are finalizing their predictions of Galaxy S4 specs. The next-generation Android-based device is sure to make several improvements on technology featured in the Galaxy S3, which is still the most popular Android smartphone of all time.

Galaxy S4 specs are most likely going to be revealed during Samsung Unpacked 2013 on March 14 at Radio City Music Hall. The big announcement is happening at 7 p.m. (EST). Be sure to tune in here for the live stream of the Galaxy S4 announcement. The Galaxy S4 release date is likely going to be one of the largest consumer electronics of the year. Android fanatics expect the Galaxy S4 to be several notches above the HTC One, which is currently considered the hands-down best Android phone on the market.

The Galaxy S4 features will likely be an advancement of all existing parts in the previous iteration of the device. The Galaxy S4 is expected to introduce a faster processor, better screen and battery life. The Galaxy S4 is also rumored to introduce a variety of new technologies. It's still unclear exactly what Samsung Galaxy S4 specs will be, but we have a strong feeling that several of the following features will be included in the Galaxy S4.

Here are the Top 5 Galaxy S4 specs Most Likely To Be Featured:

1) Eye-tracking technology known as "Smart Scroll": The Samsung Galaxy S4 will reportedly place an emphasis on software rather than featuring the best-of-class hardware in any specific category. Of all the advancements, the Galaxy S4 will be packed with a cutting-edge technologly that blows away all other new features: The Galaxy S4 will have a function called "Smart Scroll." The feature will reportedly scan a user's eyes and automatically scroll a page as the user begins reading text toward the bottom of the screen. "The phone will track a user's eyes to determine where to scroll ... For example, when users read articles and their eyes reach the bottom of the page, the software will automatically scroll down to reveal the next paragraphs of text," reported the The New York Times. Other major news outlets have reported on the same feature. If there's one feature you can bet will be included in the Galaxy S4, it's this one.

2) Eight-Core Processor: The Samsung Exynos 5 Octa processor was triumphantly announced at CES 2013 in Las Vegas. Experts and analysts immediately assumed that Samsung would include the next-generation mobile processor in their next flagship smartphone, which everyone presumes will be the Galaxy S4. Reports indicate that the Galaxy S4 will feature two sets of four-core processors. One set of the quad-core processors will be high-powered and run demanding processes on the smartphone. The other set of quad-core processors will be low-powered and run less demanding processes on the smartphone. The Exynos 5 Octa has received phenomenal results in benchmark tests, but it still hasn't be included in any commercial smartphones. Now that the Exynos 5 Octa has proven to be one of the best processors on the market, we can't imagine why Samsung would use any other processor in the Galaxy S4.

3) Android 4.2.1 Jelly Bean, Upgradeable To Android 4.2.2 Jelly Bean: For several months, Samsung fanatics were convinced that the Galaxy S4 would be pre-loaded with the next iteration of Android, which has been unofficially dubbed "Android 5.0 Key Lime Pie." Experts and analysts believed that Android 5.0 Key Lime Pie would be pre-loaded on the Galaxy S4 because it would be one of the best ways for Google, the creator of Android, to leverage media attention. If the Galaxy S4 was anything like its predecessor, the Galaxy S3, the most popular Android smartphone ever, then the Galaxy S4 was sure to generate some buzz. Unfortunately, most reports indicate that the Galaxy S4 will ship with Android 4.2.1 and be upgradeable to Android 4.2.2 in short time.

4) Galaxy S4 Price: The Galaxy S4 is expected to cost the same amount of money that the Galaxy S3 initially cost upon its release. That means that the Galaxy S4 price will be pegged at $199 with a two-year contract. That also means that without the contract, the Galaxy S4 will cost nearly $800. Another indication that the Galaxy S4 will cost $199 with a contract is because the company has lowered the price of the Galaxy S3 on Amazon to $99. That leaves room for the Galaxy S4 to be sold at $199 when it launches.

5) Galaxy S4 Display: The Samsung Galaxy S4 display is one of the biggest mysteries about the device. Most experts believe that the screen size of the Galaxy S4 will be 4.99 inches, which is significantly larger than the Galaxy S3 display. The Galaxy S4 will, without a doubt, be significantly sharper than the Galaxy S3 screen. The Galaxy S4 screen will need to be especially sharp in order to compete with the iPhone5 or the HTC One. The HTC One, which was just released a few weeks ago, has a 4.7-inch screen with a 1080 x 1920 resolution. The screen packs in a whopping 468 pixels-per-inch (PPI). The Galaxy S4 display is rumored to be slightly less sharp with a 1080 x 1920 resolution at about 441 PPI.

Other rumored Galaxy S4 features: TouchWiz UI, microSD card slot, 13 megapixel rear-facing camera, 2.1 megapixel front-facing camera, Titanium Gray and Saphire Black casing options, S-Voice command capabilities, 2600 mAh battery, 2GB of RAM and 16, 32 or 64 GB or internal storage.
