I try to be able to stop USB tethering.
I tried:
adb shell am stop com.android.settings/.TetherSettings # Unknown command: stop
adb shell am kill com.android.settings/.TetherSettings # nothing
adb shell service call connectivity 33 i32 0 s16 text # works
Latest works, but I don't know if it's very reliable like am
commands
Related, but the opposite, Is it possible to activate the "USB Tethering" Android setting from the command line?
