Using LineageOS on the FP2

Just switched from Open OS to Lineage OS. Great result.

Compared with the previous OS, here are the improvements on my side :

  • all the system is much faster and smooth
  • the camera (finally) takes instant pictures
  • no need Gravitybox and Xprivacy, all the features I needed are there already
  • more options in the settings
  • no more overwarming of the hardware

So far, just got some trouble with :

  • I loose the 4G connection sometimes, the only way I found is to reboot
  • Didn’t find the way to grant r/w permission to the SD card

So I’m really happy about the result. If someone has a solution for my two problems, will be happy for any help :wink:


The application that needs it should request the same grant-window as in android 6 (FPOOS). Works on my side.

Is the dual SIM working on LineageOS? It would be great to have more feedback on this system.

See the startpost. Yes it is working. I would suggest starting here when you want to flash LOS:

Thanks for your answers snevas. About the permissions issue, it is for Titanium which doesn’t ask for permission since it has root access. I’m going to open a new treat to develop.

Hi @snevas I can’t see that any others have had the same issue (also checked the bugtracker) but I’ve noticed that I can’t Power Off without it automatically restarting.

I’m using the latest versions 14.1-20170911-UNOFFICIAL-FP2 and

My phone is also encrypted and will let me Power Off properly once it reaches the encryption unlock screen. Should I be adding something like this directly to the bugtracker? Ps. I really appreciate all the work you and everyone else is doing on LOS :blush:

I just checked and I can confirm this, same OS, same modem, encryption too, same behaviour.

Maybe this is related to the the new modem with the old blobs. I saw that there were also new blobs released. I’m gonna build a new testbuild when these new blobs are merged. If the problem still exists after that, please make a ticket.


Did anybody test if WiDi/Miracast is working with LineageOS? I believe it has never worked with Fairphone Open OS, so it would be interesting if it does.

Now as you mentioned it, I tried to connect my LineageOS-Device (Build 20170911 / Modem 17.09.03) with Amazon Fire TV, and surprisingly it did not work anymore, it connects and I can see the very first screen, but then it’s freezing.

I re-checked that with my girlfriends FP2 with stock Android 6 and it’s working like charme.

So for me the answer is no, it does’nt work well with LineageOS.

hi, can you post logcat and dmesg when it doesn’t work?


just error logcat:
raw logcat:

and raw dmesg:


could you try the following file and report back if that fixes the miracast?

To install the file:

adb root
adb remount
adb push media_codecs.xml /system/etc/
adb reboot

Hi, I installed the file, reboot, but still the same behavior.
But now the logcat looks a littlebit different:

hmmmm. this worked for z3ntu on anycast.

Looks more like a network problem now.

Can you try a few times?

I retry it, after the second connection try, the fireTV crashed and reboots now.
So after every connection the FireTV shows the very first picture.
FP says that it is still connected.

can you try this file, too?

adb root
adb remount
adb push p2p_supplicant_overlay.conf /system/etc/wifi
adb reboot
