The Amoled screen features a pixel density of 441 pixels per inch, and it uses the PenTile matrix, which removes jagged edges on the icons. However, the drawback is that the brightness is lower relative to other smartphones, such as HTC One, although the high contrast ratio of the screen alleviates the problem somewhat, according to Tech Radar. The screen also features the Smart Stay functionality through which the phone can track the user's eye movement and enter into sleep mode when the user is not looking at the screen.
The Samsung Galaxy 4 smartphone uses the 4.2.2 version of the Android operating system out of the box, and it’s capable of accessing 2.5G, 3G and 4G networks. Its internal storage reaches up to 64 gigabytes, but the phone also includes a microSD slot, allowing users to expand the storage with a microSD card and increase it to a total of 128 gigabytes. Other features include Group Play, allowing users to play games and share documents, music and photos, and Air View, through which a user can preview the content of certain elements by hovering his finger over them.Learn more about Mobile
