4GB MicroSDHC Card

The LGL45C comes with 512MB of internal memory and a 4GB microSDHC card pre-installed expandable up to 32GB.

SDHC - (Secure Digital High-Capacity). SDHC is a removable memory card used to store data on cell phones, tablets, GPS, portable media players, video game consoles, and other handheld portable devices. The SDHC card acts as an additional storage space to the phone's internal memory expanding the total amount of data that can be stored.

SD cards come in 3 sizes: Standard, Mini, and Micro. The Standard size is about the size of a postage stamp.

Some micro SDHC cards come with adapters so that you can use them with your computer or any multi-format card reader. Unfortunately if you have an older SD card reader it may be incompatible and unable to read the SDHC card. 

Micro Cards with Adapters

 Card Readers

SD cards have two types of transfer formats "Speed Class" and UHS(Ultra High Speed)Class. These are not compatible with one another. Speed Classes are designated by Class 2, 4, 6 and 10.The greater the number the smoother the recording or streaming content and faster the transfer. UHS Speed Class is used for cam and video recorders to provide the fastest reliable and constant speed for that standard.

Speed Class is what the LG L45C uses. A Class 4 would probably suffice for most people. If you plan on doing a lot video or streaming recording, or want the fastest transfer speed available make sure you purchase a Class 10. The class is designated on the card. 

 

  

600MHz processor

The cell phones processor is a condensed and shrunken computer CPU. A CPU is like a car engine. It makes the car run. The more powerful the processor the more horsepower and speed you get.

The item description on HSN's page states that the processor is 600MHz. This is incorrect. If you review your system information you will see that the CPU displays a 800MHz 1 Core processor. I'm not complaining this is a bonus. A 600MHz and even 800MHz processors are considered entry level. Just so you'll have a comparison here are some basic differences between our entry level LGL45C and LG's current Optimus 4X HD flagship model.

CSA Listed

Listing:Adapter is CSA listed
 The Canadian Standards Association (CSA) is a nonprofit association serving business, industry, government and consumers in Canada and the global marketplace. Among many other activities, CSA develops standards that enhance public safety. A Nationally Recognized Testing Laboratory, CSA is very familiar with U.S. requirements. CSA is a stamp of approval for rigorous standards for electrical safety and electromagnetic emissions testing and an according to OSHA qualifies as an alternative to the UL Mark.

Lithium-Ion Battery

 Battery:Standard lithium-ion battery   

A lithium-ion battery is a rechargeable battery common in many types of portable rechargeable consumer electronic devices (not to be confused with standard lithium batteries.) The lithium-ion-battery has no memory loss effect like the older type nickel–cadmium (NiCad) and nickel–metal hydride (NiMH)  batteries and only a slow loss of charge when not in use.

What is PCS?

PCS (Personal Communications Service) is a wireless digital phone service for mobile users and a component of the IMT-2000 (3G) standard. Sprint was the first company in the United States to build and operate a PCS network. A number of cell transmitting antennas blankets an area for more coverage and less blind spots. As a user moves around, the user's phone signal is picked up by the nearest antenna and then forwarded to a base station that connects to the wired network. PCS operates in the1850-1990MHz bands in Canada, Mexico and the United States.

3.5mm Stereo Headphone Jack

The LGL45C uses a 3.5 mm or 1/8" connector. This is the standard size jack to connect headphones, ear buds, and external speakers to MP3 players, smart phones, and portable DVD players. 

3.2" QVGA LCD Touchscreen

HSN's Optimus V description states a 3.2" QVGA LCD Touchscreen. The specifications for an LGL45C is a 320 X 480 HVGA (Capacitive) Touchscreen.

QVGA - (Quarter Video Graphics Array)  is primarily used in smart phones, digital cameras, and other handheld devices with displays. QVGA  has a pixel resolution of 320 X 240, a quarter of the 640×480 resolution used by the IBM VGA computer monitor that set the standard in the 1980s, thus Q-VGA. QVGA resolution is measured in pixels by Height X Width. 320 X 240 means 320 pixels in height and 240 in width (see photo below). The higher the resolution the more detailed and sharper the display.

HVGA (Half-size VGA) screens have 480×320 pixels (3:2 aspect ratio), 480×360 pixels (4:3 aspect ratio), 480×272 (16:9 aspect ratio) or 640×240 pixels (8:3 aspect ratio). 

LCD - (Liquid Crystal Display) LCD displays are made like a sandwich. Take some liquid crystal solution and sandwich it between layers of transparent sheets of electrodes. Zap the sandwich with some electrical current and patterns form displaying an image. Change the amount of current and you change the color.


Touchscreen -There are two types of touchscreens. Resistive and Capacitive.
Resistive screen requires that you make contact with the display by using a stylus, fingernail, or any inanimate object and applying pressure to navigate the screen.

A Capacitive screen can sense a finger or specific electrical conductive material on or near the screen. This makes the Capacitive screen more sensitive where your finger can glide across the screen like a hockey puck gliding across the table of an air hockey game. It will take practice to accurately select icons and navigate the screen using your finger.

You can purchase a specific type of stylus that will work on a Capacitive screen to improve accuracy and also use if you are wearing gloves. A Capacitive screen can not sense a finger of a person wearing a thick glove besides accurately touching an icon would be challenging. If you are wearing a glove you will need to remove the glove, use a stylus, or purchase a special Capacitive touch gloves in order to navigate the screen.

320 X 480 - the first number represents the height and the second the width in pixels.

480 X 320 is the same display held vertically

 

Stylus - Make sure you purchase a Capacitive screen stylus not the hard plastic tip.

What is CDMA?

What is CDMA?
CDMA (Code Division Multiple Access) is one type of wireless communication technology. CDMA uses spread "spectrum technology". The signal is coded, divided-multiplexed, and scattered over a wide range of frequencies sent over a channel and reassembled at the other end. CDMA providers store your phone number and information in their database. This information is downloaded into your cell phone's internal memory. If you purchase a new CDMA phone you must contact your provider in order to have your information downloaded and phone activated.

A SIM card is used with GSM (Global System for Mobile Communications) a competing technology. A SIM card is a removable chip that stores your phone number and data. The SIM card makes it easy to switch to a new phone by simply sliding the SIM out of the old phone and into the new one. There is no need to contact your provider.

CDMA does not support SIM (Subscriber Identity Module) cards as a whole. The exception is a CDMA SIM card called the R-UIM (Re-Useable Identification Module) that was made available in China and will eventually be available worldwide. Future cell phones may have a market that supports both SIM (GSM) and R-UIM (CDMA) cards.

Although CDMA digital technology is faster GSM owns a majority of the market share (75%-82%.) GSM is a more widespread in Europe and Asia. In the United States, Sprint and Verizon networks are CDMA whereas AT&T and T-Mobile are on GSM. Most of Europe uses GSM and so does China. In India, Hutch, Bharti and BSNL are on GSM whereas Reliance and Tata Tele are on CDMA networks.

TracFone Wireless utilizes the AT&T, T-Mobile and Claro networks for GSM phones and Verizon and Sprint for the CDMA models.  HSN Optimus V customers are on the Spint CMDA network.
