One of the highlights of the LG Zero smartphone, similar to Class smartphone, is its metal body, and like other recent LG handsets, it features power and volume rocker buttons on the rear panel, just below the primary camera. The handset sports LG logo branding both on front and back panels. The Zero sports an 8-megapixel front-facing camera, which the company touts comes with the image sensor from the LG G4 flagship.
