Suddenly I am able to see a option called "developers options" just above the "about phone" option in the setting menu area. How to make the "developers options" invisible as it is before.? I mean delete it from the settings menu.
Try settings then Apps then swipe to All locate and open Settings then tap clear cache and clear data then reboot and test or try Settings then tap the 3 dots then reset app preferences
