First, we will go into the Settings of the phone and select About phone.

In About phone, we will scroll all the way down and stop on Build number. We will then tap on Build number seven times to enable developer mode.

Once we are done, we will get a notification saying that our device is enabled as a developer device.

If we tap on it again, it will show a message saying No need, you are already a developer.

Now, if we go back to the settings page, we will see that a new option has opened up called Developer options.

We will click on Developer options, and here, we will have to enable USB debugging so that we can start building the projects on the device.

We will now enable USB debugging and also Stay awake so that the phone doesn't go into sleep mode when we are developing on it.
