There are two ways to watch 3D video on your phone. Method 1: 1. Install the Rokid AR app on your phone. 2. Open the app and import 3D resources to the in-app 3D video player. 3. Press and hold the right temple button on your glasses for 8 seconds to activate the 3D mode. 4. Adjust the video left & right or up & down in the player as needed. Method 2: Install the Rokid AR app and watch online or offline 3D videos through the browser. Notes: In some locations, app stores also offer third-party online AR video apps in which you can watch 3D movies and TV online. 3D video will not display 3D effects when the glasses are connected via a wireless adapter.
