I'm trying to follow this advice on checking USB connectivity status which suggests using ADB, "or from a shell on the phone" where I should execute:
The latter seems great. But I can't find out how to start a shell on my Nexus 6P with Android 6 (not rooted). Basically, I'm asking a variant of the question: "terminal on real android device from PC", but again: I'd prefer not having to use ADB.
Is this possible? Or does this require an app and/or my device to be rooted?
