Samsung officially introduced the Galaxy S4. Set to become available towards the end of April, this new Android 4.2.2 smartphone has a similar design than its predecessor, but with a 5" AMOLED Full HD display. Just like with the S III, the processor inside the phone depends on the market you live in. Some countries will get it with a 1.6GHz octa-core Samsung Exynos processor, while others will get a 1.9GHz quad-core Snapdragon 600 from Qualcomm.
Other features include 2GB memory, Gorilla Glass 3, up to 64GB user memory plus microSD memory card slot, 13MP camera, 2MP front camera, GSM/EDGE/UMTS/DC-HSPA+/LTE Cat 3 (depends on the market), 802.11a/ac/b/g/n WiFi, Bluetooth 4.0 LE, GPS/GLONASS, NFC, MHL 2.0, and IR LED. The device measures 137mm x 70mm x 7.9mm and weighs 130g, which makes it a bit smaller and a bit lighter than its predecessor.
Special features include SmartPause, Smart Scroll, Samsung Knox and DualShot. The latter feature enables simultaneous recording on both of the phone's cameras, while Knox is a feature that lets you keep personal and business data separate, similar to BlackBerry's Secure Work Space. SmartPause and Smart Scroll are two features that use eye tracking, SmartPause automatically pauses videos when you're not looking at the screen, while Smart Scroll tracks your eye movements to control scrolling. Additionally, the device also has Air View, a feature that lets you control the phone by hovering with your fingers over the touchscreen.
