My first thought about the 3D Glasses while doing a unboxing were these things are amazing. They have a solid but not a premium feel. The display is clear and bright for a LED but not a crisp as a OLED like my Galaxy Note Edge. The Android software is very light. It doesn't take up any extra memory than needed. Every thing worked right out of the box with no connection issues. I would recommend this a great buy.
took a shot, phone the is unlocked! I am on PC metro and is 3G service, not 4G or LTE. The OS is a very pure 6.0 android. Camera is very good. So far I am impressing everyone that sees it, they guess is a 500-600 dollar phone! Completely satisfied with the offering.
