Pixel density

Pixel density - The pixel density of a display represents the number of pixels over an area of one inch. It’s measured in “pixels per inch”, or ppi. The higher the number, the more detailed and good-looking the display is.

Technology

Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Current AMOLED screens differ in such a way that they can exhibit much more saturated colors (sometimes too much) and incredibly high contrast levels, which is due to black color being completely black in AMOLED displays.

Hardware
System chip

System chip - Most modern handsets use an advanced chip that includes many of the device’s hardware modules like the processor, Wi-Fi, Bluetooth and sometimes even the wireless radio. This field shows what particular system chip (or System-on-a-Chip) is used in the phone.

Qualcomm Snapdragon S1 MSM7227  
Processor

Processor - The processor is the main computing component of a phone and is a major factor when it comes to the overall speed of the device. Some more powerful smartphones use dual-core and quad-core processors designed to deliver greater performance.

Single core, 600 MHz, ARM111000 MHz, TI OMAP 3622 
Graphics processor

Graphics processor - The graphics processor is important for the smooth operation of the system and especially in games and other applications that may involve complex graphics and animations.

Adreno 200  
System memory

System memory - System memory, or RAM memory is the type of memory that the device uses to temporarily store data from the OS or currently-running apps. The more RAM available to the device, the better the performance will be when multiple or heavier programs are running.

0.5 GB RAM / 512 MB ROM0.5 GB RAM 
Built-in storage

Built-in storage - Bigger storage capacity allows you to keep more content saved onto your device, such as more applications, photos or video. Games and video content typically take up the biggest amount of storage space.

 16 GB 
Storage expansion

Storage expansion - Some handsets allow you to expand their storage capacity by using a memory expansion card – most often microSD. Expansion memory is mostly suitable for media storage, such as photo, video or music content.

Positioning

Positioning - This field shows the positioning systems supported by the device. The most common types are GPS and A-GPS. GPS - This is one of the most widespread global positioning technologies, developed and maintained by the U.S. government. It uses satellites in order to detect your location. Works best in clear weather. A-GPS - A-GPS stands for Assisted GPS and is the industry standard for positioning and navigation. “Assisted” means that it can use local wireless networks, in addition to satellites, for quicker and more precise localization.
