I have a non-rooted Samsung Galaxy Note 3. I installed the Android SDK and Android Studio on my Windows 7 PC, but when I attempted to upload an app to my phone it didn’t offer my phone in the list of connected devices. The various sites I found on the ‘net gave various hints, but didn’t give me all I needed.
Here’s what you need to do.
- Install the Samsung Android USB driver for Windows. Various sites claimed installing KIES was enough, but it wasn’t. Other sites offered drivers, but I’m not keen on installing drivers from random sites on the Internet. Here is the official Samsung Android USB driver for Windows page on developer.samsung.com.
- Plug in your phone, and wait while it installs the drivers. Wait until this is complete.
- Enable developer mode on your phone: go to Settings > General > About device, and click on the “Build number” 7 times. This gives you a new menu, “Developer options”.
- Ensure Developer options is on, and turn on USB debugging.
- Choose “Revoke USB debugging information” to clear any existing permissions. Turn USB debugging off and on again to ensure this takes effect. (This step may not be necessary.)
- Accept your computer in the popup that appears on your phone, to authorize it.
- Run “\platform-tools\adb devices” and confirm that your device appears, and has “device” against it. If it says “unauthorized”, see above.
HTH!
