Support with casual testing
Some things are just so important that they need to be tested every day, every week, every month. Just hang around in QA group and try out the stuff that gets flagged. Without your help the developers may sit there for days more, trying to figure out the puzzle.
Join and introduce yourself “Hi, my name is X, and I own Z. How can I help?” that will do fine ;)
Unless you want to step up to become our Test Manager, but that is a whole different story.

How to install Ubuntu Touch OS
You can install Ubuntu Touch on this device using the UBports Installer on your computer.
Make sure your device is unlocked and has the required version of Android installed. Before installing, follow the device-specific instructions below:
- Please check that your device is a Fairphone 4 (FP4).
- Your device must be running the Fairphone OS version of Android 11 before installing another operating system. With a previously installed custom ROM, it won't work!
- Before installing another operating system you must unlock the bootloader of your phone manually. Follow the steps in the linked page if you haven't already.

Report an Issue for
Fairphone 4
Did the maintainer say that feature ‘works’ but you know from doing it that
it really doesn’t?
Start by searching the device issue , if you found it, hopefully the porter is on it. 'Subscribe' to the issue in case it get solved.
Couldn't find it?
Uh-oh… Well it is time to let the porter and everyone else know about the fail and send the tech magic back to the workshop for a makeover.
1. Read 'Bug Reporting' section in UBports docs on 'How to report a bug'.
2. Then (this time), head to the device repository and submit it, so the porter knows about it.
