Recently I had to factory reset my LG Stylo 3 running Android 7. Now the section in my settings that was "Developer Options" is no longer there. How can I get it back?
"Developer Options" is by default not shown on recent Android versions. To make it show up, you should go to Settings -> About -> Tap on "Build version" 7 times, and then it will come back. This action needs to be performed every time the phone is factory-reset, since it's stored as a (hidden) setting item.
