The LG G Vista is a great phone for people who want an LG G3 but don't have G3 money at the moment—it offers a 5.7-inch screen and a similar form-factor (such as those rear-facing power and volume buttons), but it's powered by a weaker 1.2Ghz quad-core processor, 1.5GB of RAM, and just 8GB of internal memory (fortunately supplemented by a microSD card slot). Verizon Wireless has pushed out an over-the-air update that hits users with a few UI tweaks.
With software version VS88011B, the phone displays a movable pop-up during calls that contains user information. Additionally, people can now take a picture from the lockscreen by dragging the camera button to the left.
This update should also increase the G Vista's speed and improve network connectivity. You can view the full support document at the link below.
