Since last update, can't shut down fairphone 2

Yes, that sounds like gibberish to me. I’m happy to provide info but it’ll need to be explained for a normal user!

Why does this remind me of this… :thinking:

First of all there are some prerequisites. I’ll describe a way assuming you have a windows PC/laptop to do the steps.

First of all you need to install some drivers and tools. The easiest way is to install the “15s ADB installer and driver” from

Then the developer options on the phone must be enabled. In the developer options then “USB debugging” and root access for ADB need to be enabled.

After those prerequisites are done, the actual steps are the following

  • connect the FP2 via USB cable to the PC
  • on the phone enable USB data transfer mode (MTP) instead of “charge only”
    • that should prompt you to confirm that you want to allow access from the PC
    • mark the check box to remember the decision and tap OK
  • on the PC, open a command prompt
  • in the command prompt type adb root and once that completes without error adb logcat > logcat.txt
    • this will log things that happen on the phone to a file on your PC
  • now shut down the phone (without torch)
    • in your case you expect this to reboot instead of actually shutting down
    • at some point the command prompt will lose connection to the phone and stop saving the log to file
  • after the phone is rebooted, unlock it and enable data transfer mode again
  • in the command prompt, type the following commands one after the other
    • adb root
    • adb shell dmesg > dmesg.txt
    • adb pull /proc/last_kmsg
  • now you can disable the USB debugging in the developer options of the phone again

That should give you three files: logcat.txt, dmesg.txt and last_kmsg. Those might help finding out the root cause.

But just to make sure: I’m no Android developer, so I won’t be able to find and fix the problem myself. It might be necessary to create a new entry in the Fairphone bug tracker and hope they find the cause.

Uh, OK. I use macs not PCs, is this going to be the same process? I can try but I’m not this sort of user normally so this is all new to me (I’ve never even reported a bug and I don’t know where/how to do that).

Ok, for Mac, don’t use the first link, but follow the instructions in section “How to Install ADB on macOS” of

The rest of the steps should be identical.

OK I’ve tried following all these instructions but it’s not working for me (adb command ‘not recognised’ apparently).

I’ve added a comment to the bug tracker but I am not sure any attention will be paid as it’s marked as ‘solved’. I still don’t understand why this issue has suddenly reappeared :confused:

Thank you urs_lesse brilliant of you to find that one out, and share with us.

I still had to use the flashlight method to shut down my phone, which is really annoying as I go to the cinema and theatre a lot! But now my flashlight and back camera don’t work at all (!!!) I can shut down my phone. But I’d rather have a working camera (yes, I’ve made a thread about it as I can’t find anyone else having that problem).

Needing flashlight to shut down was fixed in an update a while ago, for that reason there were no replies to this topic in the past months. Please check whether you are running the newest version.

If your phone is up to date (Fairphone OS 19.08.x or above) your problem is likely unrelated to the one discussed here. In that case, plase use the other thread you made to discuss your camera problem, so we can keep the discussion in one place.

It took a while before I could update my phone, but even after that I had to use the flashlight to turn off the phone, but now the flashlight doesn’t work at all and neither my camera.
