Pulling out and plugging in USB cable changes global setting
Summary
The Developer Option "Select USB Configuration" unexpectedly sets itself to "Charging" after pulling out and plugging in the USB cable. Image: e-0.1-201811031782-nightly-s2
Steps to reproduce
As a prerequisite the device is not attached to a computer and in the Developer Options the option "Select USB Configuration" is set to "MTP"
- 1a Plug in the USB cable to a computer
- 1b the option "Select USB Configuration" shows as value "MTP" and the storage is accessible from the computer
- 2a Pull out the USB cable
- 2b the option "Select USB Configuration" shows as value "Charging"
- 3a Plug in the USB cable to a computer
- 3b the option "Select USB Configuration" shows as value "Charging" and the storage is not accessible from the computer
What is the expected correct behavior?
I would expect that
- in step 2b as value is displayed "MTP"
- in step 3b the storage is accessible from the computer
Pulling out and plugging in the USB cable should not change the value of an option in the global settings.
