How to Change Preferred Network Type with Tasker

In this guide, we will show you how to change your preferred network type with Tasker. This app is probably among the most feature-rich tool for your Android devices. It holds a plethora of options that automate near-about all the important functionalities of your smartphones. But for most of its tasks to be effectively carried out, it required access to the system partition aka root. However, the app has undergone some changes in recent times and now allows for the execution of many different system-level tasks even without the need to root your device.

And in this guide, we will be making use of one such task. Today, we will show you how to change your preferred network type with Tasker. Just to make things easier for the end-user, we will also list out the steps to transfer this task right onto the Quick Settings panel itself. But before that, let’s try and understand what exactly is happening in the background and how Tasker is able to carry out these tasks without root.

The Permissions Required for this Task

So how are we able to create and execute core level tasks without root? All this is made possible via the Android Debug Bridge or more popularly known as ADB. Using a couple of ADB commands, we would be able to change the network type right from the Tasker without the need for admin rights. In this regard, the first command will be WRITE_SECURE_SETTINGS. This gives the required permissions to any app to read or write secure system settings.

This permission isn’t made available to any third-party app including Tasker. So we will execute an ADB command alongside the Tasker’s package name to grant it read/write permission. Then we will be using the ADB WiFi permission. This permission will create an open network port on your device for the third-party app to access it. But the thing is that this port is now accessible to all the third-party apps and isn’t just limited to Tasker. This might prove to be risky.

So keep in mind that whenever this ADB WiFi permission is executed, you will get an Allow USB Debugging prompt on your device. If you have manually requested the same, then it is well and good. On the other hand, if it pops up all of a sudden, then some third-party app is making use of this open port, hence you should deny this connection right away. So these are the two permissions that we will be using in order to change your preferred network type with Tasker. Follow along.

The Prerequisites for this Task

  • First and foremost, download and install the Android SDK Platform Tools on your PC. This will provide us with the necessary ADB binaries.
  • Next up, enable USB Debugging on your device. This will be needed so that your device is able to recognize the ADB commands executed from the PC. To enable it, head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging.

That’s it. You may now proceed with the steps to change your preferred network type with Tasker.
