LG's $180 large-screen Stylo 3 smartphone is now available to customers of Boost Mobile and Virgin Mobile, boasting a 5.7-inch HD touch-screen display, a 1.4GHz octa-core processor and an enhanced stylus.

The LG Stylo 3 also includes 16GB of onboard storage, 2GB of memory, a 13-megapixel rear-facing camera, a 5-megapixel front-facing camera that captures photos automatically when the subjects look into the lens, a 3,200mAh battery for up to 25 hours of talk time, and a built-in fingerprint sensor for device and user security.

The handset, which Boost and Virgin announced on March 14, can also be used as a mobile hotspot and runs on the Android Nougat 7 operating system. Both prepaid, no-contract carriers offer a variety of cellular service plans for customers.

One enhancement over earlier versions of the phone is the included stylus, which can be used to write, sketch, doodle or annotate on the device's screen for capture and use in documents and emails, as well as for other tasks. The latest fiber tip on the stylus is thinner than the version used on the LG Stylo 2, allowing users to be more accurate and precise as they compose their inputs on the display.

Also included are a pop memo feature that lets users add notes anywhere from any place on the display and a pop scanner feature that lets users quickly capture, trace and crop any picture on the screen.

To help prevent loss of the stylus, a pop-up message on the Stylo 3 will alert users when the stylus is separated from the device.
