Fairphone 2 (FP2)



  • @Flohack @nanu-c Testing the new camera with GStreamer-droid is highly appreciated. I believe that using 7.1 should solve issues with the new camera modules due to no need for any wrapper.



  • @peat_psuwit Pardon for my intrusion. I would like to ask about the working status of sensors in this build. Concretely I mean the accelerometer, compass and front light sensor (am I missing some?). Could you check? Thank you.



  • @jezek Accelerometer works as the screen rotates correctly. LED doesn't work, probably due to the permission issue. SensorStatus doesn't show values from the compass, but I'm not sure if it's due to the port or other problem.



  • @peat_psuwit Thank you for your answer. Compass is not working on current (default) build, that's why I asked, to see if new Halium (7.1) fixes the problem.

    By the "front light sensor" I meant the proximity sensor on the front (near the front camera), that is used to turn off the display while calling (and if not working properly, I always switch to flight mode with my ear during calls). I think, it is used also to automatically regulate brightness.



  • @jezek Normally proximity and brightness are separated. So you can have perfect b rightness regulation but still the display does not switch off during calls.



  • I will gladly test this once images are provided. it's a bit early now as this is my primary phone.



  • So I built the images and flashed my (daily) phone. 🙂
    So far, everything works as exspected. Camera does not, the phone needs a bit longer to awake.

    But I am not completely shure if it is running on Halium now, because my whole data and apps are still there.
    Is there a way to confirm, that it is using Halium now?

    I will test it further and report here.



  • FP2, findings and differences to legacy version:

    • camera does work with gstreamer-droid patch and is superfast
    • after turning flightmode off, it is not needed to enter SIM-pin again
    • waking up from sleep is delayed by some (5?) seconds, what makes it hard sometimes to answer a call, because you have to wait until the swipe is working
    • I can't get a MTP USB connection, when I unplug the device, my pc informs me about using another network connection, lsusb identifies the device as:
    Bus 003 Device 007: ID 0fce:7169 Sony Ericsson Mobile Communications AB FP2
    


  • @Luksus Wakeup from sleep delay affects all Halium 7.1 builds, and the fix is already available, needs just a few lines of config. MTP is a bit tricky to get in, but we will be able to add it, so its also just a known todo than a blocker 😉



  • @Luksus is the data connection toggle enabled after switching off airplane mode? https://github.com/ubports/ubuntu-touch/issues/30 Is the most annoying issue to me currently.

    Also, does the flashlight work ?



  • @Fla the toggle stays enabled but gets inactive when switching flightmode on, and there is also no dataconnection available anymore. After switching flightmode off, the toggle gets enabled again and data connection is also there.

    If you are referring to the bug, where this toggle stays always inactive, regardless of the connection state, then I can say, that I did not encounter this issue so far.

    Sometimes the system isn't aware of the mobiledata connection and I need to toggle mobiledata on and off multiple times, that the system is getting it. This happens for example, when switching WiFi off. As I remember, this did not happen with the legacy port.

    The best Improvement so far is: No more random reboots - yeah!

    I also managed to get rid of the wake up from sleep delay.
    So this build is very usable as daily driver for me.



  • @Fla flashlight does still not work.



  • Update:

    • even, if I not have to re-enter sim pin after turning flightmode off, sometimes the sim locks it self randomly
    • sadly, I encounterd 2 reboots since I flashed it. Both while charging the battery and doing nothing with it
    • to activate a hotspot, I need to turn off WiFi and enable hotspot from within the settings


  • Another Update:

    • Reboots are still much less than on legacy version and happen mostly while charging
    • activating hotspot is a bit fiddly, but works
    • automatic switch between mobile network and WiFi does not always work reliable
    • just encountered that the whole wireless display/aethercast thing is missing 😕


  • @Luksus as I stated on the appropriate github issue, I am able and willing to send my new camera module to anyone willing to tackle that issue and would need the module 🙂



  • @Emphrath I also have the "new" (second) camera-module 😉
    Are you talking about the flashlight?



  • @Luksus yes I am. This is presently the only thing keeping me from going back to UT, and I am now considering the old camera module in order to have a working flashlight... has there been a new cam module since the one we're talking about ? I was unaware. I understand that getting this flashlight to work is not a priority of this project, considering the work on halium , unity, and porting to other devices, but I can't get my head around why the former works and not this one. Maybe it requires some "porting" of its own, but since fairphone openos made the kernel sources for this device available, I wonder what's up!! I'm not a developer and only have basic Linux knowledge so I thought I could help that way.



  • @Emphrath No, there were only two camera modules. I believe the biggest part of the FP2 owners have the newer one. So no need to send yours to someone.
    I often thought about looking into the flashlight problem, but always came to the conclusion , if even Rajanathan did not get this to work yet, who made a lot for the FP2, then I can't make it work either.... 😉



  • @Emphrath the problem is that there is maybe a new flash device node in the /dev/ tree (lets assume this for a moment). However, the Android camera stack is a total mess of its own, and any slight change can totally disrupt it. I remember when the new module came out we couldnt even use it for weeks (or was it months) due to the Android part just screwing up.
    Eventually someone will get it to work, but yes, our priorities are geared towards other things at the moment. But I am pretty sure @peat_psuwit could analyze it with the right module. So he might be a cndidate to send one to 😉



  • Sorry, get occupied with some other stuff. I'll look into the Aethercast problem. However, that's not the top priority.

    Although I've never tested the new camera module (I don't have one), I think that the stack should work with both versions. If you have the new modules and care to compile the Halium part from source, I encourage you to try it out.

    For the flashlight (via the battery indicator), there's a possible fix available as the latest lxc-android-config package in xenial_-_gst-droid. Again, if you care to compile the Halium part from source, you could try that on the old and the new camera module. However, there's a possibility to burn your flash. So, please make sure you have a spare module before trying it out. I've burnt mine during my fiddling, and I have no spare module, old or new. So, I'll not be able to test it myself.
