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.	217 ppi	217 ppi
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 S2 MSM8655	Qualcomm Snapdragon S1 QSD8250
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, 1000 MHz, Scorpion	Single core, 1000 MHz, Scorpion
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 205	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.	0.75 GB RAM	0.6 GB RAM / 1024 MB ROM
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.	8 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.	microSD, microSDHC up to 32 GB	microSD, microSDHC up to 32 GB

Cellular
CDMA CDMA - Code Division Multiple Access. A technique of multiplexing, also called spread spectrum, in which analog signals are converted into digital form for transmission. For each communication channel, the signals are encoded in a sequence known to the transmitter and the receiver for that channel. The foremost application is digital cellular phone technology from QUALCOMM that operates in the 800MHz band and 1.9GHz PCS band. CDMA phones are noted for their excellent call quality and long battery life.	800, 1900 MHz

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.

Regulatory Approval
FCC approval FCC approval - The Federal Communications Commission (FCC) is an independent United States government agency, directly responsible to Congress. The FCC was established by the Communications Act of 1934 and is charged with regulating interstate and international communications by radio, television, wire, satellite and cable. The FCC's jurisdiction covers the 50 states, the District of Columbia, and U.S. possessions. Every wireless phone device that is sold in the U.S. has to be tested and approved for sale by the FCC.

FCC measured SAR FCC measured SAR - Working closely with federal health and safety agencies, such as the Food and Drug Administration (FDA), the FCC has adopted limits for safe exposure to radiofrequency (RF) energy. These limits are given in terms of a unit referred to as the Specific Absorption Rate (SAR), which is a measure of the amount of radio frequency energy absorbed by the body when using a mobile phone. The FCC requires cell phone manufacturers to ensure that their phones comply with these objective limits for safe exposure. Any cell phone at or below these SAR levels (that is, any phone legally sold in the U.S.) is a "safe" phone, as measured by these standards. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg).
