xiaomi mi2s android version 4.1.1 jro03l miui version miui-jlb24.0 I cannot see anywhere under Settings - About Phone that will allow me to turn debugging on. Is it hidden of just not available? The reason I ask is I have trouble copying files off when I connect to my Windows 7 pc via the usb cable. The device manager says it cannot install the driver correctly (and I have read elsewhere that trying to use the xiaomi_usb_driver.rar does not work). Thanks for your time.
