Rated 4.2 out of 5 by 27 reviewers.
Rated 2 out of 5 by 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. December 21, 2013
Rated 5 out of 5 by 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. August 25, 2013
Rated 5 out of 5 by The best phone Ive ever owned!!! This is the best phone i have ever owned. ive left it for the iphones, lastly the iphone 5, but ill never do it again unless lg comes out with a newer model of basiclly the same phone. Mine has been updated to the windows 7.8, but i was happy with just the windows 7. the full slide out keyboard is the best. the only downside is the apps are way behind, and phone cases are slim to none. LG, please please bring out a newer lg quantum c900!!! June 2, 2013
Rated 4 out of 5 by 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. September 7, 2012
Rated 1 out of 5 by Disappointed I am overall quite disappointed in this product. The first phone virtually died before the warranty was up. I was sent another refurbished phone but of course had lost a great deal of my information and many pictures. I have had the second phone now for about 6 months and have had to replace the battery twice and now it is again not holding a charge. I like the pull out keyboard which is why I chose this phone but these other issues cause me to not consider it again. July 1, 2012
Rated 5 out of 5 by outstanding phone this phone is the best phone i have ever had. i recommend this phone to anyone who is into windows products. i can't wait for a new quantum 2 (or whatever number they call it) June 2, 2012
Rated 5 out of 5 by Great Phone I agree with the others that left a review. Its weight gives me the feeling of a durable strong phone, very tough. I've dropped it a couple of times, not even a scratch. Oh and if not for the hard keys I think It would next to impossible to enter a credit card number without making mistakes as I did with my previous phone. May 23, 2012
Rated 5 out of 5 by Screen Size, OS, Speed,Everything Love this phone, It's the heavier of the 2 windows phones but it's most durable. Can't get any better as far as battery life. 2-3 Days on one charge. Xbox Live Friendly and games are easy to play, Superfast! March 22, 2012

LG Quantum, built on the Windows® Phone OS 7 glance-and-go experience platform, was designed to be easy to use and do more in fewer steps. LG Quantum's convenient full QWERTY keyboard enables even faster communication for those longer e-mails when a touch screen just won't cut it. The superfast 1GHz processor, 720p HD video capture and playback, and exclusive “Play To” feature that streams your media to a DLNA-DMR entertainment device make LG Quantum an incredibly cool, and seriously fun, productivity tool.
