Hi!
I have a Samsung Galaxy Tab 7.0

I need to reboot my device and in order to do so, need to select usb debugging mode. However, all of the options under debugging are greyed out. The only one not greyed out is "Chose an App to debug" by clicking that, it says "none", and helps in no way. I've tried every way of trying and enabling it. Checking for knox, turning developer options on and off, rebooting my tablet, plugging in my tablet and unplugging it. NOTHING works!!! Plz plz help.
