Does what it says on the tin . just ensure your android phone does support UVC/OTG you can check here : http://www.samsungsfour.com/tutorials/complete-list-of-samsung-galaxy-smartphones-with-otg-support-usb-on-the-go.html It does not support iphones and there is not app to make it work. Dont even try I wouldn't not fly with ti but it s great in the field for a friend to maybe watch the 1st person view on his phone when your flying . Mine arrived with no manual but thats not a biggy just google it :) You can also use it on your windows PC i used OBS and it showed up as a webcam
This thing works well on my Samsung note 9. I can even make the video split screen for my VR headset. Pretty cool device. I recommend it for beginner Fpv. The app I use to get it to work on android is "go fpv" by vertile in the app store. Comes with one micro USB to micro USB cable, one micro USB to USB C cable, one 5.8ghz antenna, the module and a tin metal box (slightly larger than an altoids mint tin box).
