Samsung Galaxy S4 is an impressive Android device released in March 2013, featuring a pretty large 5-inches display, a powerful Octa-Core CPU (formed by a Quad-Core clocking at 1.6 GHz and a Quad-Core clocking at 1.2 GHz), and two cameras, a 13 MP back side camera and a 2 mega-pixels front camera.

Samsung decided to equip this phone with a great performance Octa-Core CPU (actually, there is a Quad-Core ticking at 1.6 GHz and an extra Quad-Core speeding at 1.2 GHz), bundled in an Exynos 5 Octa chip and a great 2 GB RAM. An excellent aspect of the S4 is its big 64 GB internal memory and an SD memory card expansion slot, more than enough to store hundreds of apps without thinking about running out of space at all.

Samsung made the Samsung Galaxy S4available just in many different color options: black, blue, red and white. Regarding its body design materials, the S4 is majorly created with Polycarbonate. Samsung made a really good job making this phone as lightweight as 4.59 oz. This phone has an amazing design, with a thickness of just 0.31 inches. While this cellphone just has 5.38 inches long and 2.75 inches wide, it is still able to fit a a 5" display.

The Samsung Galaxy S4 is equipped with a incredible 5 inches screen with a 1920 x 1080 (Full HD) resolution, making everything look absolutely great. Its screen uses Super AMOLED capacitive technology, and can detect multiple fingers at the same time.

This cellphone has two cameras, a 13 MP back camera and a 2 mega-pixels front camera. Though it's 13 MP might sound great the back camera sensor size is quite small it takes less detailed pictures than it should. It is also able to film videos in Full HD 1920x1080 at 30 fps. Additionally, the camera has a high number of cool characteristics: auto-focus, flash, digital image stabilization, smile detection shooting, face detection shooting, HDR mode and geo tagging.

The S4 features an incredible 2600 mAh Li-Ion replaceable battery, enough to provide this cellphone with a great battery life.

This cellphone includes Wi-Fi capability (which can be provided to other devices acting as a wireless modem), 4G LTE high speed connection type and also HSPA+ internet connection, that is a bit slower 4G type or the fastest 3G connectivity, supported by HSDPA, HSUPA, UMTS and EDGE technologies. The S4 uses two Micro SIM cards so it's able to work with two different phone numbers and even different carriers at the same time.

This phone also features many interesting features like Bluetooth (for communication with other bluetooth devices, computers, and accessories), GPS, Infrared Blaster and NFC (to trigger actions, transfer data or make payments by holding your device close to another NFC device or tag), and multiple sensors like Light Sensor, Proximity Sensor, Accelerometer, Gyroscope, Barometer and Compass.

Samsung is selling the S4 for only 145 dollars, which is a real gift comparing with other similar cellphones. No matter if you love photography, want a gaming cellphone, need a work cellphone or are looking for a cellphone mostly for internet broswing and social networks, you will definitely love this phone.
