How to unlock and enable Developer options of any Android Phone??

What are Developer options??

Developer option of Android phone is a set of tools by user can change/modify or debug the Apps/program via USB debugging mode.

On Android 4.1 and lower, the Developer options screen is available by default. On Android 4.2 and higher, you must enable this screen. To enable developer options, tap the Build Number option 7 times. You can find this option in one of the following locations, depending on your Android version:

·         Android 9 (API level 28) and higher: Settings > About Phone > Build Number

·         Android 8.0.0 (API level 26) and Android 8.1.0 (API level 26): Settings > System > About Phone > Build Number

·         Android 7.1 (API level 25) and lower: Settings > About Phone > Build Number
