|Primary <strong>Camera</strong> is able to capture photographs and usually videos, The most important characteristics of a camera are the resolution (measured in megapixels), lens focus type (fixed or automatic), higher megapixel cameras are known to capture higher quality photos, but not always a good measurement of the photos quality.
|13MP + 2MP
|Flash <strong>Flash Light => </strong> There is commonly two types of flash lights are used in camera mobile phones, LED Flash (LED flash offers lower power consumption with drive circuitry that takes up very little room, LEDs can be strobed faster than any other light source), Xenon Flash (xenon flash produces an extremely intense full-spectrum white light for a very short duration)
|Operating System <strong>OS => </strong> Every computer system run on a base software called Operating System (OS). Operating System controls all basic operations of the computer (such as smartphone, PDAs, tablet computers and other handheld devices). The Operating System allows the user to install and run third party applications (apps), apps are used to add new functionality to the device.
|User Interface <strong>UI</strong> or user interface of a device is the look and feel of the on-screen menu system. How it works, its color scheme, how it responds to button presses, all of these things are part of the user interface.

|CPU <strong>CPU</strong> (Central Processing Unit) mostly known as processors, CPU processes instructions in order to carry out certain functions that make your device operate properly. Processors are often described as the brain of computers, smartphones and tablets, Smartphones and tablets rely on processors to carry out their every task, Processors are an incredibly important factor in selecting any type of computing device, including your smartphone.

|Internal Storage <strong>Internal Storage</strong> is a data storage space (flash memory) mostly used in smartphones, tablets and other electronic devices where operating system, apps, music, photos, videos, files and other user data Is stored.
|16GB / 32GB
|Card Slot <strong>Memory Card Slot</strong> is a special slot for inserting a memory card. Memory cards allow you to expand the phone's built-in memory, A memory card (sometimes called a flash memory card or a storage card) is a small storage medium used to store data such as text, pictures, audio, and video, for use on small, portable or remote computing devices such as mobile phones, mp3 players, digital cameras.
|Sensors <strong>Sensors</strong> are electronic components that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure and location, The output is generally a signal that is converted to use in computing systems, a location sensor, such as a GPS receiver is able to detect current location of your electronic device.

|SIM <strong>SIM</strong> (Subscriber Identity Module) is a small card that contains mobile network subscriber's account information. This allows the phone using the card to attach to a mobile network. The SIM card is most commonly associated with GSM and UMTS mobile networks. Moving a SIM card from one phone to another allows a subscriber to switch mobile phones without having to contact their mobile network carrier. SIM cards can also be used by a phone to store limited amounts of data, such as phone numbers and text messages.
|Bluetooth <strong>Bluetooth</strong> is a wireless communications technology for exchanging data between mobile phones, headsets, computers and other network devices over short distances without wires, Bluetooth technology was primarily designed to support simple wireless networking of personal consumer devices.
|Infrared <strong>Infrared</strong> connectivity is an old wireless technology used to connect two electronic devices. It uses a beam of infrared light to transmit information and so requires direct line of sight and operates only at close range.
|Wi-fi <strong>Wi-Fi</strong> is a popular wireless networking technology using radio waves to provide high-speed network connections that allows devices to communicate without cords or cables, Wi-Fi is increasingly becoming the preferred mode of internet connectivity all over the world.

|Capacity <strong>Battery Capacity</strong> is a measure (typically in Amp-hr) of the charge stored by the battery, and is determined by the mass of active material contained in the battery. The battery capacity represents the maximum amount of energy that can be extracted from the battery under certain conditions.
