The bigger the screen size is, the better the user experience.

The device has a standard memory slot (such as an SD or micro SD card slot) so that you can either extend the internal storage with affordable memory modules or you can retrieve data, such as photographs, easily from a memory card.

Damage resistant glass (such as Corning Gorilla Glass or Asahi Dragontrail Glass) is thin and lightweight, and can withstand high levels of force.

The battery is removable and can be replaced by the user if broken.

It can be charged and operated with a standard USB cable connected to your computer, or with a USB power supply.

The manufacturer offers a branded wireless charging kit. To charge the device, you simply put it down on its charging base.

It can transfer files, music, photos via USB, no need to install additional software.

All DLNA certified products are compatible with one another. When different devices are connected to the same network, data can be transferred easily between them.

NFC (near field communication) allows a device to perform simple wireless transactions.

802.11ac wireless works on the 5GHz frequency range. It offers higher transfer rates, improved reliability and improved power consumption. It provides advantages for gaming and HD video streaming.

With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.

A smaller size indicates that the process to create the chip is newer.

ANT+ is a wireless protocol similar to Bluetooth Smart, and is very power efficient. It is mainly used for fitness monitoring devices such as heart rate monitors and cadence sensors to connect to other devices, eg. sports watches, smartphones and cycling computers.

This is a cross-platform benchmark that measures the performance of the CPU. (Source: Primate Labs, 2016)

This allows to manually set the exposure.

You can shoot multiple pictures in a row.

AMOLED displays, also known as active matrix OLED displays, offer higher refresh rates and consume less power than other types of displays.

SAR (Specific Absorption Rate) describes how much radio frequency energy emitted by the device will be absorbed by your body. The rate is measured at head level. The legal limit is 1.6 W/kg in the USA.

A higher memory bandwidth means the memory can be accessed faster and therefore data can be retrieved quicker, having a positive effect on the performance.

A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.

When the camera shutter is open for a long time, more light is absorbed by the sensor. You can use this slow shutter speed to produce vivid night time photography, or capture the trajectory of moving objects such as motorway traffic.

Deeper blacks and Brighter Whites, The display literaly disappears, you wont be able to distinguish the screen from the bezel

for lollipop update

I can change my icons if I want by downloading an app and I have the use of widgets so I don't need to open an app, I can see and do everything with my widgets already on my screen.

Can record slow and fast motion videos

A touch of a button transforms the device to a kid friendly mode which prevents them from accidently accessing any of the chat contents or medias not intended for kids. .Quite handy while leaving the phone unsupervised. .at home with kids around.

This device is more Friendly than other Samsung devices

Può essere usato come telecomando sia per TV sia per DVD e Blueray

The device has a display with three full subpixels per pixel, resulting in a sharp and crisp picture. Pixels in some displays (like AMOLED) share one subpixel to preserve space. This can result in a less crisp, slightly blurred image.

It can be updated directly by the OS vendor, so no need to wait until the manufacturer or network provider releases an update.

A dedicated camera button allows you to take snapshots more easily.

IPS (In-Plane Switching) is a technology used for LCDs. It was designed to overcome the main limitations of normal TFTs TN-matrices: relatively slow response times, small viewing angles and low quality color reproduction.

More microphones result in better sound quality and enable the device to filter out background noise.

With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.

Pixel size is the surface area of each pixel on the camera sensor. Larger pixels can absorb more light. This can result in better image quality and improved low-light performance.

SAR (Specific Absorption Rate) describes how much radio frequency energy emitted by the device will be absorbed by your body. The rate is measured at hip level. The legal limit is 1.6 W/kg in the USA.

AirPlay allows wireless connection of Apple devices with external screens or speakers. You may stream computer screen, video and music from iOS devices, play games like on consoles or present your slideshows easily on your TV.

The amount of time it takes the camera to take a photo, without having to focus.

It takes less time for the camera to turn on and take a first picture.
