Android Gingerbread Operating System
The LG Viper 4G runs the Android 2.3 operating system (dubbed Gingerbread). It features a cleaner, more refined interface with new icons, improved top notification bar, and more intuitive navigation.
Multitasking in Gingerbread allows you the ability to run more than one app at a time. If you're playing a game, you can easily switch to an incoming e-mail and then switch back to the game without losing your place. And like the previous version of Android ("Froyo"), Gingerbread provides support for Adobe Flash Player 10.1 for access to the full Web.
The onscreen keyboard makes it easier to type thanks to additional spacing between the keys and larger font sizes. And the more you use the keyboard, the easier typing will be as the enhanced suggest feature records previous input history to make better suggestions.
The Viper 4G also brings one-touch access to the popular Google mobile services you use every day. It also provides easy access to both personal and corporate e-mail, calendars, and contacts supported by Exchange Server and Gmail. And through Google Play, you'll get access to thousands of useful applications, widgets, and fun games to download and install on your phone, with many more apps being added every day.

Wireless Emergency Alerts (WEA), also known as CMAS, is a part of a national alerting system called IPAWS (Integrated Public Alert and Warning System) that enables emergency management officials to rapidly disseminate the warnings and safety information via text alerts to wireless phones based on the phones’ geographic location. The Federal Emergency Management Agency or FEMA is responsible for receiving the alerting information and forwarding the alerts to participating wireless carriers such as Sprint. Such alerts may come from the President of the United States; the National Weather Service, state or county public safety officials. This system is integrated into the same national alerting services that serve television and radio today.

As much as I like it you have to keep things in perspective... this IS NOT meant to compete with the super phones like the EVO 4G LTE or the Samsung Galaxy III LTE... or the Google Nexus. It is far above the "entry level" class of phones too! I have to admit, I felt like I was cheating my wife by getting a "free" phone for her... but after using it I feel that I ripped Best Buy for getting the phone free on an upgrade... and trading in her old EVO 4G for a $65 credit! This is by far the best free phone I have ever seen.... and I worked for Sprint as a store manager for 4 years.
So here are some bullet points on why to consider the LG Viper;
* Smallest of the 4G LTE Android phones - For my wife the size of the other LTE phones was a tad bit too big. The size of this phone is perfect for her.
* Speed - This phone hands down "smokes" the EVO 4G that she had. When I was doing updates I was amazed of the speed of the phone. This thing is a fast and powerful as you need!
* Covers the basics well - Good camera, access to the web, facebook, gmail, apps, etc. For the NON TEENAGER... this phone works very well! If you are a a power user (business or teens) then you may want to explore the higher end phones. But if you need a phone for your day to day basics this phone is for you! (and then some!)
* Value - Like I said, I cannot believe that this phone is free. If money is a consideration then look at the LG Viper before dropping $150 to $200 on a larger more powerful handset... then look at this phone and compare the "true" needed features that you will use daily.Read more ›
Purchased the LG Viper two weeks ago on Amazon since they had a discounted price ($0.01) compared to Sprint ($59) with my two year upgrade. I think I am exactly the customer this phone was designed for. I like new technology, but I am not willing to pay $150-200 for a new phone, so when this one came out that was on the 4G LTE network, had a fast processor and great screen, I immediately went looking at reviews. CNET had reviewed it, as well as Endgaget and several others. They all spoke of the green construction and great camera, but it came out in April and was followed by the "high dollar" phones from Samsung and HTC so you didn't hear anything about this phone after that.
The LG Viper 4G LTE is a very nice looking handset that has a lot of amenities. The weight is good and the size is near perfect for me. I may eventually go with a case for it, but currently don't see an immediate need to. Normal use and keeping it in my pocket have not shown any scratches or wear on the exterior. It comes with a 4GB micro SD card so storage has not been a problem. It says it will support a 32GB card if you want to carry all your music with you.
I was upgrading from another LG phone, the Optimus S, so the button layout was the same. It was a change switching for physical buttons to soft keys, but having them in the same place made the transition easy. The extensive use of recycled materials is a nice feature, but doesn't sway me one way or the other.Read more ›
The battery life is bad but not worse than other Android phones - which is why i use JuiceDefender (app) to keep my battery lasting all day.
HW quality is solid, though i wish the back cover were rubberized. NFC is cool, takes a while to get used to it and get into the mode of pulling out your phone instead of your wallet.
I'm not gonna hold my breath for Sprint to turn on LTE here in San Diego, so i can't say much about the LTE capabilities BUT as a 3G phone, it's solid.
My newest assessment of this phone sharply contrasts with the old. While I like this phone in general, one major issue, and I mean major!, is the battery life. It is the worst!!!!! You cannot use the phone's functions for half an hour without the battery draining significantly. I spend most the day constantly recharging it.
Now LG has given us an update for the Android os to 4.0 which is great in thought. Now my phone is super buggy, slower than ever in loading anything and I'm also getting dropped calls very often.
I am ready to throw in the towel, pay a ridiculous early termination fee and go elsewhere because it is only a daily source of frustration. Thank you black Friday! You're the perfect opportunity for me to get a great deal on a fabulous HTC phone!
