Rated 1 out of 5 by One Major "deal-breaker" Problem The battery is close to worthless. It must be charged multiple times daily and I don't use the phone more than once or twice a day. I do not use the data so that's not the problem. I text, perhaps, twice a day. I ordered another battery and it is also close to worthless. If the battery does not work, the phone is nothing more than a weight in my pocket. I now carry the spare battery in my purse in case I have an emergency. The features of the phone are fine, but what's the point if I can't use them because of a dead battery? May 28, 2014
Rated 1 out of 5 by I have never been more disappointed. Upon receiving the LG Viper, I was greeted with an average-looking smart phone. It seemed to have all the bells and whistles that one would expect. I was dead wrong. Within minutes of using this device, the truth was realized - the LG Viper is a substandard cell phone. Never before have I used a product that freezes more constantly, has so much trouble accessing the internet, and fails to recognize touch screen activity. These are only the more prominent issues. There's also the factor of a poor quality camera (both front and back view), among other things. Connecting to 3G and 4G services is troublesome and does not always work as it should. Even when connected to a strong Wi-Fi signal, extremely slow internet is observed. I could get into all the problems that I've had with this phone, but it would be a waste of time. The bottom line is that the LG Viper is one of the worst smart phones in the market. May 8, 2014
Rated 1 out of 5 HATE IT It may seem nice, but It constantly Freezes. Sometimes the Phone Update un-wanted things. And the Browser it REALLY slow. It Also Dies Quick. LG's are really not a good product anymore. Cant wait to get my Galaxy. April 26, 2014
Rated 2 out of 5 shameful you get the phone thinking its nice because the front camera and the features they tell you about but it really isnt all that. this phone is for an adult that only really texts and talk and may play games and have a few social network apps. if you use the phone a lot, the screen starts to freeze, and then i have to restart. it would even turn on and off by itself. the battery doesn't even last that long. and the front camera isnt that good, the memory doesnt last that long.

Rated 1 out of 5 by The worst of the worst This phone is the reason you must do your research before purchasing a product. Every problem on every review I had with this phone. It is definitely not the phone that you want to get stuck in a contract. And the sad thing is it has one best displays for 4" phones. NO, ICS dose not help the phone either. Oh, I manage to drain the battery in 96 minutes! November 6, 2013
Rated 5 out of 5 by Great Phone My wife and I both have the LG Viper phones. They are easy to use and reliable. We have had LG phones before (Olympus) and loved them. When it was time to upgrade we chose the Vipers, and glad we did October 23, 2013
Rated 1 out of 5 by Horrible. its like when i first got this phone i thought this phone was the best, but then the tables turned and next thing i know everything started to freeze when i use instagram and writing a message to someone the status bars will go away and the 3G will come on, i live in a 4G area why is it going to 3G? i don't live underground. my calls will be dropped left and right like 1 hours and then my battery life dies and it charges for 2 hours and then died fast. i am not gonna pay so much money for one phone with bad working specs. this phones needs some improvement.

Rated 1 out of 5 by never purchase a LG again I have had 3 replacement phones from Sprint since I received my brand new LG Viper 4G LTE. I will never buy another LG again the worst experience in my life. Phone shuts down on its own, screen freezes, phone heats up, several replacement batteries, and the list goes on and on...
