I have a Samsung Galaxy Ace and I've encountered a strange issue. When I was connecting my mobile to the PC I unchecked the box for "USB debugging mode" and did my work without issue. However, after some time passed and I again tried to connect my mobile to same PC, it was unable to connect. When I checked my settings, I noticed that USB debugging had become re-enabled again. Is there anything I need to set to disable USB debugging permanently, or is this the default behaviour of the Samsung Ace?

I would uncheck it and then reboot before connecting to anything. –  Matthew Read Nov 14 '11 at 20:52
why reboot, does it actually require... –  Abbas Nov 14 '11 at 21:07
No, it shouldn't require that, but I thought it might work. –  Matthew Read Nov 14 '11 at 21:15
