Some of the pre-installed apps (like Netflix) are tablet apps, so you must use it as if it was running on a tablet. There are three ways:
Via the included AirMote
First, pair your AirMote to the projector. Head over to this article: How to pair the AirMote? for instructions.
After pairing your AirMote to the PicoPix, you can press the mouse-pointer button on the top right to activate mouse mode. When using the AirMote, the OK button has no effect. Press the Mouse-Pointer button to “click” something on the screen. You can scroll by pressing and holding this button, then moving the remote (dragging gesture). Mouse mode can be deactivated by pressing any up/down/left/right key.
Via the built-in touchpad
Use two fingers to scroll the screen, and tap something to ‘click’ it.
Via an external mouse
If you would like to use a wired or wireless mouse that you already have, you can do so. If It's a USB mouse, just plug it into the USB-A port of the projector. If it's a wireless mouse, pair it to the projector in the Bluetooth settings screen.
In this way you’ll be able to navigate within apps that don’t respond well to the arrow/OK keys.
