I turned on usb-debugging on my HTC One X just to see if I could idenitify it when using Android SDK. Now the usb-debugging mode always shows up when I connect the phone to my Windows and Linux computer.
I have Andriod 4.1.1 on it; it's not rooted. The settings in developer options is off for everything. Developer options itself is also set to off. Despite this, I always get a notification on my phone that it has connected in usb-debugging mode when I connect with usb-cable. When I check the developer options, they are mysteriously set to on again.
When I try to change the settings for the usb connection, I get the settings for Portable hotspot & tethering and not the settings to charge or use mass storage. Strange!
This behavior prevents me from using the mass storage option. On my Linux computer, I cannot see any files on the device.
Are there any global configurations/settings I can clear to fix this? What else should/could I do?
