We will be updating this article throughout this evening's Galaxy S4 event, so please check back for more information as we learn more details from Samsung. 

Arguably the biggest event of the year for Samsung, Thursday evening's Unpacked 2013 event in New York City could very well decide what kind of year Samsung's going to have, as the Korea-based electronics giant is prepared to announce the follow-up to its most successful smartphone ever released, the Samsung Galaxy S4. 

If you're looking for any and all information related to the Samsung Galaxy S4, you've come to the right place: This page will serve as our veritable hub for all things Galaxy S4, including links to other stories we're writing all night long about the phone's specs, features, price, release date and more. Everything you need to know about "The Next Galaxy" is right here.

Event Information

Samsung informed the press on Thursday that doors to Unpacked 2013 will open at 6 p.m., just one hour before the official presentation begins at 7 p.m. The official show will be closed to the public, but will be live streamed onto the Internet (we have it for you here, and embedded below as well).

We assume the event will last roughly 1-2 hours at most -- just one hour if the Galaxy S4 is the only thing we're seeing today, two hours if Samsung's feeling particularly confident -- and then the press will be able to go hands-on with the phone itself. Our reporters are attending Unpacked 2013, and we will return with videos and update this page when we have them.

Live Stream

Samsung has a live stream page for Unpacked 2013, which features a live-updating comments system and Instagram feed. But why leave when there's a perfectly good live stream embedded below? Radio City Music Hall attendees and online viewers alike can watch the Samsung Galaxy S4 event beginning at 7 p.m. EST:

Specs

While we do not yet know the specs of the Galaxy S4 -- we will include a link to a story as soon as Samsung releases information tonight -- we believe the Galaxy S4 will be powered by Samsung’s own quad-core 1.4 GHz Exynos 4 processor and an ARM Mali-400 for its GPU. Both chips are said to get an upgrade in 2013, and the Samsung Galaxy S4 is said to feature a new Exynos 5 Octa CPU, which was initially used in the company’s Chromebook model -- the new processor is said to have eight cores for enhanced work flow and power efficiency. Last year's ARM-based GPU is also said to be replaced by a new 1.9 GHz Snapdragon 600 chip from Qualcomm, which will help power the display and the phone's operating system (likely Android 4.2 Jelly Bean, since we're not expecting Android 5.0 Key Lime Pie until Google's i/O Conference in May). The new Smapdragon chips don't quite touch NVIDIA's top-of-the-line Tegra 4 SuperChip Processors, but Qualcomm's 600s clock in at about twice as fast as the Exynos 4 chip in the Galaxy S3.

Display And Appearance

It looks like Samsung is following its own formula when it transitioned from the S2 to the S3: Make the screen a little bigger, but the phone a little thinner. The Samsung Galaxy S3 measured 136.6 x 70.6 x 8.6 mm, but the Samsung Galaxy S4 is said to measure slightly longer at 140.1 mm and slightly wider at 71.8 mm, but much thinner than its predecessor at just 7.7 mm thick, which is just a tad (0.1 mm) thicker than the iPhone 5. 

Furthermore, the 4.8-inch, 1280 x 720 Super AMOLED display from the Galaxy S4 is said to be replaced by a 4.99-inch, 1080 x 1920 Full HD SoLux Display to give a dense pixel density of 450+ ppi. We've also heard Samsung may implement its experimental phosphorescent organic light-emitting diode (PHOLED) displays, which can be up to four times more power efficient than the current OLED screens in the Galaxy S3, but we're not sure if those PHOLED displays are fully ready for mass production just yet.

Price

We fully expect Samsung price the Galaxy S4 exactly as it did the Galaxy S3. Since the Galaxy S3 has seen a price drop (Samsung is selling last year’s model anywhere between $49 and $99) Samsung can now sell the Galaxy S4 at last year’s prices. If the company follows last year's plan exactly, the Galaxy S4 may very well cost $199 for 16 GB or $249 for 32 GB. Without a two-year contract, it’s possible Samsung could also sell the new handset at $599 and $649 for 16 and 32 GB storage models, respectively, like it did last year.

Release Date

Last year, Samsung unveiled the Galaxy S3 on May 3 but didn’t release the device until May 28, and that was in Europe. The US didn’t even get the Samsung Galaxy S3 until June 21; it’s possible Samsung will roll out the Galaxy S4 in a similar manner, releasing the phone in the US roughly a month after its public unveiling.

But while Samsung could certainly capitalize on building hype for a prolonged release date, we don't believe the Korea-based company would come all the way to New York City just to tell the home crowd that their Galaxy S4 release date isn't for another two months.
