I just picked up an LG Optimus G for use in development. I followed the instructions to turn on USB debugging, but the option is grayed out. I can’t move the slider at all. (I previously had some Samsung phone and it worked fine but the usb port broke after a week so I returned it).
Is this common? (disabling the option for USB debugging)
Is my only choice to root the phone?
I know there are a ton of phones, but I suspect most of them operate in the same way for this sort of thing.
