I'm using a Huawei P20 Pro.

I'm trying to use adb according to this guide: https://developer.android.com/studio/command-line/adb.

I have enabled developer options. I can enable USB debugging, but if I go back one screen and return, USB debugging is off again.

And ideas on how I can enable USB debugging?

  • This sounds like a device/manufacturer specific issue. Did you try looking for related settings in the developer settings screen? Maybe revoke all USB-debugging authorizations and then reconnect? – Yoav Feuerstein Oct 15 '18 at 7:12

What worked for me is choosing "File Transfer" on android when you plug the USB instead of "Charge only"
