LG G4 not recognised by Android Studio

Question

I just got the LG G4 phone, turned on developer options mode, tried running an app from Android Studio but it can\'t recognise my phone. I even tried switching from MTP to PTP b

Answer 1

I had same problem. I was checking Developer Options after plugging USB cable, the USB Debugging option was unchecked and grayed out while cable plugged. I unplugged USB cable, checked USB Debugging option and plugged USB cable again, it worked.

Answer 2

Check your phone, it will ask to install driver on PC. Afterwards android studio will see your phone

Answer 3

Here's what I had to do:

1. Install the LG Mobile Drivers: http://lg.com/us/lgeai/drivers (latest at the time of writing: here)
2. Disable USB debugging if currently enabled (this was key for me)
3. Enable USB debugging
4. Plug into computer
5. Allow USB debugging when prompted (will show RSA fingerprint, check "always allow").
6. Trust the computer when prompted (allow access)
7. Switch to PTP
8. Install USB driver when prompted
9. Wait for the driver to finish installing on your PC

adb devices should show your phone now. If you don't get some of the prompts above, try unplugging and re-plugging your device. Also try different USB ports on your machine.

Answer 4

Try tap "adb devices" in shell window( or command window) 1) if still nothing displayed, it must be not related to studio, please check whether drivers is properly installed or register in system(Different system has different methods). 2) if displayed like "0b63d5xxxxxxxxxx device", it should be studio's problem, check view option or reinstall android studio.

Answer 5

None of the answers here worked for me until I turned on USB debugging mode in Developer Options.

For completeness, the steps are:

1. Go to Settings > About phone > Software info
2. Tap "Build number" 7 times until it says that you're a developer
3. Go back to Settings, and tap on the new "Developer options" item (second last in the menu)
4. Enable "USB debugging"
5. Plug in your phone
6. Change from MTP to PTP mode
7. Allow the computer to access your phone (there should be two messages - one of them should be for the RSA key fingerprint)

And that should do it. Run adb devices and you should see the phone.

Answer 6

You have to activate developer mode for your device.
