I want to USB tether my Samsung Galaxy Tab A (10 in) to my laptop so that I can use it as a second monitor via SpaceDesk in locations with crappy Wi-Fi. So this question will be about USB tethering, but if you know of a way to reliably use my tablet as a second monitor that doesn't require USB tethering, I'd love to hear it!

The tablet doesn't have cellular connectivity, and perhaps for that reason, USB tethering doesn't appear under Settings / Connections (or anywhere else that I can see). I'm looking for any practical way to enable it. This can involve rooting or installing a modded OS, although of course if there's a more straightforward way, I'd prefer that route.


You can enable usb tethering through adb shell. Root is needed in order to execute these commands:

After adb setup on your machine (if you haven't already setup adb, please see detailed instructions here: Download Minimal ADB and Fastboot Tool & Setup guide, perform these commands:

The following commands call ConnectivityManager.setUsbTethering(boolean enable) in Android 4:

adb shell su -c service call connectivity 34 i32 1 turns on USB tethering.

adb shell su -c service call connectivity 34 i32 0 turns off USB tethering.

(For other Android versions replace 34 with the following setUsbTethering calling codes per Android version):

5.1.0: 30
6.0.1: 30
7.0.0: 33


Is it possible to USB tether an android device using adb through the terminal?

  • Thanks. I did this (using code 33 for Android 7), but the "USB Tethering" option still isn't showing up. Any ideas?

  • I think some manufacturers make this feature unavailable due to a variety of reasons probably in favour of carrier specific tethering apps, you may also oversome this using some third party usb tethering apps e.g foxfi, pdanet to mention a few Feb 11 '18 at 15:38
