  • Size
    5.5 inches (~72.7% screen-to-body ratio)
  • Resolution
    1080×1920 pixels
  • Pixel Density Pixel Density (PPI) is refers to the concentration of pixels on a particular display, measured in pixels per inch (ppi). Pixel density is calculated by dividing the diagonal pixel resolution of a display by its diagonal size, higher pixel density better display quality.
    401 ppi
  • Display Protection Display Protection => Gorilla Glass is a special alkali-aluminosilicate glass shield with exceptional damage resistance that helps protect mobile displays from scratches, drops, and bumps of everyday use, It is always better to go for a smartphone with Gorilla Glass for that added protection and peace of mind.

Network

  • SIM SIM (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.

Connectivity

  • Wi-fi Wi-Fi 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.
  • GPS GPS The Global Positioning System is a satellite-based radio navigation system, GPS permits users to determine their position, velocity and the time 24 hours a day, in all weather, anywhere in the world, In order to locate your position, your device or GPS receiver must have a clear view of the sky.
  • Bluetooth Bluetooth 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 Infrared 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.
  • NFC NFC (Near field communication) is a set of standards for smartphones and similar devices to establish peer-to-peer radio communications with each other by touching them together or bringing them into proximity, usually no more than a few inches.
  • Wireless Charging Wireless Charging (Inductive Charging) uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.
