Samsung Galaxy S 4: 5-inch 1080p display, 802.11ac, and much more

Samsung made the Galaxy S 4 official at an event held at Radio City Music Hall. Led by JK Shin, head of Samsung mobile, the company showed off its new flagship smartphone--and it's exactly what we've already seen in the multiple leaks.

Front and center on the Galaxy S 4 is the 5-inch Super AMOLED 1080p display, using the new Corning Gorilla Glass 3 and sporting a whopping 441 pixels per inch. Stunning, to be sure. Additionally, this smartphone is the first to sport 802.11ac Wi-Fi support, the fastest you'll be able to find in any home at this point--also compatible with 802.11a/b/g/n as well, alongside Bluetooth 4.0. An IR blaster is included, similar to the one found on the HTC One, and you also get a removable 2,600 mAh battery. Other important specs include 2 GB of RAM, and the choice between 16, 32, and 64 GB of built-in storage. Naturally, the phone supports LTE.

One major change is the camera system--a 13 megapixel camera on the back, and a 2 megapixel shooter up front. Samsung says the rear camera on the Galaxy S 4 can take more than 100 pictures within 4 seconds and then composite them together. You can also take images with the front and rear cameras at the same time, which will then get integrated into the same image.

Software additions include things like Smart Pause, which will pause a video automatically when you look away from the display, and then continues playing when you look back. The Smart Scroll feature scrolls you through web pages and email messages by monitoring your face and wrist movements. This is all running on top of Android 4.2.2 Jelly Bean.

The Samsung Galaxy S 4 will launch in 55 different countries, spread amongst 327 different carriers, beginning in late April. You'll be able to get it in either black or white. Samsung has yet to announce pricing.
