What people are saying

Rated 5 out of 5 by from Excellent for the price! I've had this LS720 for a year and it's kept up with everything I have needed it to do within the constraints of my budget. The camera features blew my mind with voice activation and the quality is 1 megapixel from being considered professional quality shots. The memory issues are common across this platform because memory is the most expensive you're getting a lot of memory to run the stock apps most people want and know how to Facebook and Google. You have plenty of memory to store a ton of still photos and some long videos. Because this is a NEXT GEN phone...whatever you do not save on your phone you can UPLOAD to a server via EMAIL or whatever! It's sooooo fast! Then you can clear your memory for the next round of pics/vids! However, there is always room for improvement. The voice quality is very poor in this phone at times. I don't know if it's the phone service providers or my phone or the other person not having a good phone! There's a lot of variables involved in cellular phone service and this phone is capable to get things done in several ways. I highly recommend LG products. They're durable and high quality performance. This is my 4th LG phone.

Rated 1 out of 5 by from No Internal Storage makes this phone useless I've had this phone for years, and if you only want to use it to text, make calls, and browse the internet then it works fine. But it has virtually no internal storage and thus can't install more than a few small apps, and external sd cards can only be used for storing audio and image files. So if you want to do anything more with your phone, you're better off buying something else.
