This app allows you to fast open the Developer options. The standard steps for opening the Developer options is Settings -> Developer options. Using this app those options will appear automatically when you connect your device to USB or when you disconnect your device. Then you can choose which options do you want to enable or disable as you did before.

Using this app you don't need to manually enter the settings for development as the application will do it for you automatically. Additionally you can choose whether to display the Developer options. It can be displayed only when you connect your device to USB as well as both connect and disconnect your device.

Note for Xiaomi users:
Developer options will be opened at USB events (if enabled) only if Autostart permission is set (Settings -> Permissions -> Autostart).
