I think that data on/off switch should come as a part of core Android, not some additional app/widget, right?
Do you have developer mode active and, if so, is the 'mobile data always active' switch on?
yes, I have developer mode on and
no, the 'mobile data always active' switch is off
It should be, ya. And most are. Not sure why yours isn't. Maybe because it is unlocked?
Mine was originially locked to MetroPcs,
Then metropcs unlocked it for me. so at this point of time the phone is completely unlocked.
but still no on/off button
Hi how I do my phone do not work network locked
Other than using a widget I'm out of suggestions
After you slide drop down select the 3 dots then hit button order youll see dara box in the list...hold then move
Unfortunately, the desired button is not either. See screensho
Try resetting the quick launch panel. Open the panel and select menu option button reorder. Then tap 'reset' and see if that restores the button.
