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
