Hide developer options for Android devices

We know that after Android 4.x developer options are hidden by default, open method:

set--about the phone--version number , a number of consecutive clicks (typically 4, 5 or more), return to see the developer options come out.

So how do we hide this option?

Most of the online tutorials are:

Settings-apps-settings (Programs)-Erase data

At this point, all the settings are cleared and the developer options are hidden.

Of course, if your phone is rooted, we have a better way.

Entering the/data/data/com.android.settings/shared_prefs directory with re (Root Explorer), we found a development.xml file inside.

Change the value of show to false.

Of course, if not, you can delete the file.

Restart takes effect.
