An app that allows end users to test the features of their device

This is a fork of the Fairphone 2 checkup app that has been modified in order to work on other devices as well.

It allows you to test various components of your phone:

  • Screen

  • Speakers

  • Microphones

  • Mobile connectivity

  • Wi-Fi

  • Vibration

It can be useful when you need to diagnose an issue with your device.


Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
