I have just flashed a VARIANT=user build on Dolphin and enabled adb in the developer menu but adb is unavailable on the Dolphin: $ adb devices List of devices attached 0123456789ABCDEF unauthorized $ adb shell error: device unauthorized. Please check the confirmation dialog on your device. Seems like adb is waiting for user authorization of the adb session. On Android you'd get a dialogue on the device to authorize adb, but Firefox OS doesn't provide the same functionality. I believe we are controlling adb access by turning it off when a lock screen is active instead.

Kai-Zhen, what is the desired UX regarding remote debugging or adb on a user build? I.e., is it supposed to be available? Is it supposed to engage the user with a dialog that needs approval? I take back what I said about Firefox OS not providing the dialog functionality in the description. I have seen it on other devices :)

This might actually be fixed for the dolphin already, but it'd be good to know how the UX is supposed to be anyway.

I think we should have a design to let the user know and confirm when remote debugging or adb on a user build. But I don't have a good idea now. I'll ni our UX for some suggestion. Jenny, do you have any idea? How should we handle this requirement in our setting?

Hi Kai-Zhen, it seems we need a dialog for confirmation. Do you have a reference screenshot on this? Thanks!

I think there is a confirmation dialog already, but it's been patched away here for some reason. I was just curious on the current UX behavior, so I can verify that I see the correct thing.

This has now been fixed on dolphin. adb is available on user builds.
