Samsung Galaxy S4 is a high quality Android phone launched in March 2013, counting with a 1900 megahertz Quad-Core processor, a quite big 5-inches multi touch capacitive screen, and two cameras, a 13 megapixels back-facing camera and a 2 megapixels front facing camera.

Regarding its design, this device is made with Polycarbonate. Even though this cellphone is just 5.38" long, it still manages to contain a 5" display. Being just 0.31 inches thick,this phone is extremely thin and practical. Samsung did an amazing design job making this phone as lightweight as 4.59 ounces. This cellphone is for sale in a wide range of colors: black, blue, red and white.

This cellphone has a beautiful 1920 x 1080 (Full HD) 5 inches display, providing this phone with a perfect graphical experience. This display uses Super AMOLED capacitive technology, and can detect multiple fingers at the same time.

Samsung decided to equip this phone with a Qualcomm Snapdragon 600 APQ8064T system chip, backed up by an extremely powerful 1900 megahertz Quad-Core processing unit and a big 2 GB RAM. Graphic calculations often uses lots of CPU processing time, so it has an additional 400 MHz Adreno 320 graphic processing unit to help with that calculations. The S4 comes with a huge 64 GB internal storage memory and an external memory card slot, enough to install hundreds of apps without having to worry about running out of space at all.

The S4 features two cameras, a 13 mega-pixels back-facing camera and a 2 MP front-facing camera. Although it's 13 megapixels may seem amazing the back-facing camera sensor size is quite small which makes photographs have less details and worse lighting than they should. It is capable of filming videos in 1920x1080 (Full HD) at 30 frames per second. Additionally, the camera features multiple interesting characteristics: flash, auto-focus, digital image stabilization, face detection shooting, HDR mode, smile detection shooting and geo tagging.

This phone comes with a big capacity 2600 mAh Li-Ion removable battery that provides this phone a great battery life.

This cellphone counts with wi-fi connection (which it can provide to other devices as a mobile hotspot), 4G LTE high speed connection and also HSPA+ connectivity, that is a bit slower 4G variation and fast 3G data connection, supported by HSDPA, HSUPA, UMTS and EDGE technologies. This device works with a Micro SIM card for GSM carriers.

This phone also comes with a great numbre of cool characteristics as Wireless charging system, NFC (Near Field Communication), Infrared Blaster, Bluetooth and GPS Geolocation, and multiple sensors like Light Sensor, Proximity Sensor, Accelerometer, Gyroscope, Barometer and Compass.

This phone costs about 160 dollars, quite close to other similar cellphones. It doesn't matter whether you will use it for work, are an amateur photographer, are looking for a gaming device or will use it mostly for social networks and internet browsing, this device is the correct option for you.
