If you never turned it on, you should be good to go, or just head to Developer mode again and turn it off. If you’re connecting an Android to a Mac, you need to turn USB debugging off. When you go back to the Camo app, if you don’t see a pop-up asking whether you want to allow USB debugging, unplug and plug the cable back in. Scroll down to find USB Debugging and toggle it on.

Once turned on, you can find it in Settings > System > Developer mode, though some of the navigation menus may differ based on your Android phone. To do this, head to Settings > About phone and then tap Build number seven times to enable Developer mode.

(If you have issues, try another cable.) For Android phones connecting to a Windows PC, you’ll need to enable USB debugging mode.

If you don't want to go the wireless route, plug in a cable from your phone to your computer after you tap Connect a Device in the desktop app-make sure it’s a quality cable, ideally the one that came with your phone.

Scan the QR code and your phone should connect immediately. Camo recently added wireless capabilities, so all you need to do is press the Wi-Fi icon in the Camo app on your phone and then press Connect a Device in the desktop app.

Launch the app on your PC and smartphone.

It’ll work with Windows 7 (64-bit) or newer, and macOS 10.13 or later. Android phones need to be running version 7.0 and up, and iPhones need to be on iOS 12 or later.

Download the Camo app on your Mac or Windows machine.
