About its construction, this phone is mostly made with Polycarbonate. Samsung has made a very nice job making this phone weight only 4.59 oz. Samsung is offering this cellphone in multiple color variations like black, blue, red and white. The S4 is extremely thin and comfortable, being just 0.31 inches thick. Though this cellphone just has 5.38" long and 2.75" wide, it is still able to fit a a 5" screen.

This device is equipped with a incredible 1920 x 1080 (Full HD) 5" display, which makes it impossible to even distinguish the pixels taking part of the display. Its display uses Super AMOLED capacitive technology, and allows multi-touch gestures.

Samsung equipped this cellphone with a high speed 1.9 GHz Quad-Core processing unit, bundled in the Qualcomm Snapdragon 600 APQ8064T system chip and a big 2 GB RAM. Collaborating with graphic rendering, this phone also counts with a 400 MHz Adreno 320 graphics processing unit. The S4 counts with a 64 GB awesome internal storage memory and a slot for an SD memory card, more than enough to store hundreds of apps without having to worry about how much storage capacity is left.

This cellphone offers Wi-Fi capability (and it can be provided to other devices around, acting as a mobile hotspot), LTE (4G) high performance connection type and also HSPA+ connection type, that is a slower 4G type or the fastest 3G connection type, over HSDPA, HSUPA, UMTS and EDGE technologies. This phone uses a Micro SIM card for GSM carriers.

This cellphone is equipped with two cameras, a 13 mega-pixels back-facing camera and a 2 MP front facing camera. While it's 13 MP may seem incredible the back-facing camera has a small 0.326797" sensor which makes photos be less detailed and darker than you would expect. The Samsung Galaxy S4 also films Full HD 1920x1080 videos at 30 frames per second. Additionally, the camera includes a lot of cool features: auto-focus, flash, face detection shooting, digital image stabilization, HDR mode, smile detection shooting and geo tagging.

This device also comes with many interesting features like Bluetooth (4.0), GPS Localization, Infrared Transmitter and NFC (to trigger actions, transfer data or make payments by holding your cellphone close to another NFC device or tag), and multiple sensors like Light Sensor, Proximity Sensor, Accelerometer, Gyroscope, Barometer and Compass.

This cellphone comes with an incredible 2600 mAh Li-Ion replaceable battery providing this cellphone an incredible battery duration.

This cellphone is being sold for $ 129, which is really cheap for such a great phone.
