Do I understand correctly that in the 7th Android, it is not so easy to make different Tasker, Automate, etc. without rooting
That is, everything has become so secure
Yes, you understand correctly. Without root not to do.
Yet, by the way, is not clear - why do you disable GPS?
While GPS nobody uses - it does not consume the battery.
If the problem is not to give applications access to your location, the better this access on and off. However, also hands.
