Samsung has officially announced the Samsung Galaxy S4 at its Radio City Music Hall event in New York City.It packs a new 4.99″ Super AMOLED screen with a resolution of 1920 x 1080 pixels, which adds up to a pixel density of 441ppi. The screen still a new PenTile matrix, though it probably won’t matter much at this kind of density.
The phone will launch on 327 mobile operators in 55 countries starting at the end of April, with 3G and 4G / LTE versions available, and its polycarbonate case will initially be available in two colors, white and black.
The 5-inch screen features a 1080p resolution, as expected, is covered with Corning’s Gorilla Glass 3, and it’s known as a “full HD super AMOLED” screen with 441 pixels per inch. The phone comes with 802.11ac Wi-Fi (which also runs on the standard a/b/g/n bands), Bluetooth 4.0, and Cat 3 100 / 50 Mbps LTE, and also comes with an IR blaster like the HTC One. Key specs include a removable 2,600 mAh battery, 2GB of RAM, and 16, 32, or 64 GB of storage. Also of note is the new processor — either a Samsung Exynos 5 or Qualcomm Snapdragon S4 Pro processor, depending on the region.
One of the more interesting software additions is S Health — Samsung’s clearly been paying attention to the wearable computing trends. The phone’s sensors can monitor your fitness level and surroundings, making it a full-fledged fitness tracker — it’ll integrate with a number of Samsung accessories, as well. The phone features a built-in pedometer for tracking the number of steps you take — or run — during the day, much like Fitbit’s line of devices. However, sensors in the phone also allow it to measure the ambient temperature and humidity of the room you’re, all of which feeds into the S Health app itself. Diet tracking is integrated as well, with the app pulling able to pull caloric information from a database of common food items.
Samsung also added some touch-free gestures to the Galaxy S4: Air View and Air Gesture. The former lets you hover your fingers over the screen to pull out contextual data or preview the content of messages, while the latter lets you control features like your music, answering calls, or scrolling without having to actually touch the screen.
