What People Are Saying

Rated 2 out of 5 by from CONS:Fonts too small to read The font size is about two point and one needs a microscope to read the numbers in the phone book. Do not consider this phone.

Rated 5 out of 5 by from Good Choice I've been using this phone for three years and am about to upgrade as my contract is ending. I would recommend LG highly. This phone has acted as my tablet and most important business tool. I have even invoiced my customers from it I was able to do that because I took the time to set it up the way I wanted it in the beginning. It was easy and no I'm not in computers. I work in the food industry. Hats off to LG for a great product and Windows for clear thinking.

Rated 4 out of 5 by from excellent smartphone with few drawbacks I have been using my optimus quantum for about a year now and I love it. It is simple to use, faster than most equivalent superphones and very well featured including a full qwerty keyboard, which is what drew me to it. Its battery lasts well and can be used to watch movies or play games for a couple hours before you have to worry about battery running out, something I have noticed lacking in others it is not without its flaws however, first off the vibrate is a little weak, which is a little annoying and the camera lacks good nite photography. Worst of all however is its lack of expandable memory, simply being able to slot a micro SD card into it would greatly improve its ability to store movies, but it was left out.
