A:Answer No adapter needed. I have this very same SPro 2 Projector, there are a few ways to hook up your phone, I have the Galaxy S7 edge waiting for the Note 8 so I can get my Note phone back. But anyway, it has screencast, I wirelessly cast my S7 Edge screen through the projector. There is also an app that you download its a remote control for the projector. The remote is really awesome, what ever is shown on the projector's color touchscreen shows on the remote app on your phone. You can use the projector as charger for your devices, memory card slot, HDMI port, SUB port, earphone jack, SD card slot with tray, WiFi, Bluetooth, Google playstore. This ZTE projector is crazy awesome, its the Swiss army knife of all projectors!
