Even if you are nice to root your Android phone and install a custom ROM, you can still try some features and settings that are not enabled by default. Every Android phone is equipped with the ability to enable development options, which allow you to test certain features and access parts of the phone that are usually locked. As you might expect, the development options are cleverly hidden by default, but it's easy to activate if you know where to look.
Find your Android construction number
Before you can enable development options on your Android phone or tablet, you first need to find the phone's construction number. On most phones you can simply type construction number in the search bar, but here you will find it on some popular devices:
Google Pixel : Settings> System> About phone> Construction number
Samsung Galaxy S8 and later : Settings> About phone> Software information> Construction number
LG G6 and later : Settings> About phone> Software information> Construction number
HTC U11 and later : Settings> About> Software information> More> Construction number
OnePlus 5T and later: Settings> About phone> Construction number
View development options  Once you have found the screen with your Construction Number, you have to press the seven seven times. That's right: seven times. After a few cranes you will see a small pop-up warning that "You are now X steps away from being a developer" with a number that counts down with each additional crane.
After the seventh button, a message says "You are now a developer!" and the developer options unlock as an option in Settings. Some phones will contain a general message of tinkering with your Android phone, but you can simply press OK . While many of the options are strict for developers, including things like USB troubleshooting and bootloader unlocking, you will also find things like high frequency audio codes, chin options and CPU use among the gears. Experiments at your own risk.
Turn off development options
While Google used to require a factory reset To clear your phone with development options, it is easier to jettison now. In most Android phones running Nougat and later, you see an on / off key at the top of the screen, allowing you to turn off developer options. The screen turns gray and when you leave it will be away from your phone. To get it back you must follow these steps again.
