Developer Mode on Android phones adds a set of special features to the device's developer settings, but sometimes demanded by ordinary device users (for example, to enable USB debugging and subsequent data recovery, installation of custom recovery, screen recording using adb shell commands and other purposes).

Unlock and enable Developer options

1. In the phone settings, find the 'About phone' item.
2. Find 'Kernel Version' or 'Build Number' in the menu.
3. Press this item several times in succession. After a few taps, notifications will appear stating that Developer Mode will be enabled soon.
4. At the end of the process, you will see the message 'You are now a developer!' - this means that the Android developer mode has been successfully enabled.
5. To enter the developer mode menu, go to 'Settings' - 'For Developers'.

The 5 Android Developer Options that can be customized

1. OEM Unlocking
Android devices give you the freedom to install a custom ROM, which replaces the default OS with a new one. To do this, you must first unlock your bootloader.

2. Running Services
Running Services lets you view how much RAM currently running apps are using.

3. USB Debugging
USB debugging lets your Android device interface with your computer by using certain commands.

4. Default USB Configuration
By default, when you connect your phone to your computer, it will only charge your device, and you need to select the data transfer mode each time.

5. Override Force-Dark
Enabling this slider makes all apps use a dark mode
