Did you make sure to install the adb drivers for your phone? Also make sure you have enabled debug mode on your device. If neither of those are the issue, maybe check here for further troubleshooting help.

From what I understand, adb drivers are automatically included with Android Studio. I'm 99% sure

Make sure you enable developer options on your phone and check 'Enable USB Debugging'

On your Phone... Go to your settings: Go to "about phone" Tap on "Build Number" 7 times. This enables developer options Go to Developer options (in the settings app) Check - Enable USB Debugging

When you connect your phone to your computer with Android studio running, you should see a dialog box asking for permission for your computer to debug your phone. Tap Yes and accept those permissions.

You should be set from there! Hit 'Run' in Android Studio and you should be good to go.

Hit me up on here if you have any further questions!

Build number would probably be under software info.

I can't say for sure if it's under software info, as every phone is different. You'll want to poke around in each one of those sub menus to find the build number.

After that, just follow the other instructions I wrote above and you should be ready to go.

Feel free to keep chatting with us here if you need more help! I started out on Treehouse about a year ago, and I was able to get a job in the industry after 6 months, so don't get discouraged!

I just had this issue, one thing you might want to make sure is that you have the LG Suite installed. I guess it might just be a security measure LG added, but as soon as the app was installed my phone let me choose what USB mode you are in and Android Studio was able to pick it up in the devices.

You can find the LG PC Suite at the LG site
