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.

167 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.

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.

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

Capacity

Capacity - The bigger, the better! However, battery capacity is not the only factor that has an effect on battery life. Those include the chipset in use, the software running on the device, as well as the consumer's unique usage pattern.

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.

NavigationYes  
Regulatory Approval
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).
