Here is a new build (security patch level 2019-02-05):

The first version is build from the official sources, but includes some additional changes to the kernel (source):
  • Fixed: Sometimes during phone calls the screen will stay off due to the proximity sensor getting stuck (rewrote parts of the sensor driver).
  • Fixed: Screen shift bug (cherry-picked from LineageOS 15.1).
  • Fixed: Sometimes the device will not go to sleep when the battery is low (~15%), causing the battery to drain very quickly (restored some lines of code that were present in the original charger driver).

The second version is purely build from the official sources:
lineage-14.1-20190222-UNOFFICIAL-wt88047.zip



Whenever I build it for myself I'll publish it here as well. I will make no promises though.

In the second (untouched) version, yes.

I noticed that there is another problem leading to non-responsiveness during calls, but this has nothing to do with the proximity sensor:
After some time (days to weeks) my device would (seemingly randomly) lose its mobile data signal. At the same time it would not go to sleep anymore and also keep the screen off during calls. At this point, only a reboot would help. It happens so rarely to me that I find it hard to even get a useful log :eek:.

If you suspect that the proximity sensor is still misbehaving in the fixed build, would you please test it with some sensor app? The sensor is placed next to the front camera. Make sure that there's no object near it (~10cm), then move your hand close to the sensor (~1cm) and away from it again. The sensor status should alternate (far→near→far, or 5→0→5). If the sensor is erratic, a kernel log (dmesg) might help me understand what's going on.

I don't understand how this is possible, since these builds are virtually identical except for a few lines of kernel code. As a workaround you can flash the unmodified version first and then flash only the kernel (boot.img) from the version that includes the fixes.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1.2 (Nougat), which is designed to increase performance and reliability over stock Android for your device.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

    Supported Firmware:

    Downloads:

    wt88047: https://goo.gl/FNbbMP
    wt86047: https://goo.gl/YHufVo

    Note:
    It is the firmware LineageOS supports and all users are expected to be on this very firmware. So it's mandatory that you flash this firmware via TWRP if you're newly installing Lineage.
    You don't need to reflash this everytime you update you LineageOS build.

    To add on:
    There seems to be some confusion with this post in general. If you are coming from a stock MIUI Lollipop build, it is highly unlikely that you would need to update your firmware with the one above since Xiaomi hardly updates its firmware on older devices. Otherwise, if you are not sure what firmware you currently have, I urge you to flash the firmware linked above.

    Why should I even flash this firmware?
    The simple answer is that this firmware is known working with LineageOS builds and I am currently running it. Running other versions of the firmware (Like the Kitkat firmware) may warrant unheard of bugs and / or bugs that have been squashed long ago.

    When should I flash this firmware?
    This firmware should only be flashed once, anytime before the first boot into LineageOS.

    DEV Update 20170418

    Let me address certain issues:

    1) There would soon be a 7.1.2 build on the official downloads page, things to take note are as follows...
    • Update your Gapps (Preferably the latest Gapps from OpenGapps)
      7.1.2 causes old 7.1.1 Gapps to crash SUW and that is not very nice to deal with
    • Wait patiently for the build... no ETAs please.

    2) ARM64
    I started adding arm64 support for our wt88047 over 2 weeks ago. Due to a few factors such as being fairly busy, a broken device and no build server, I have not even tried compiling the source. There will be no guarantees that it would come to official since we have the 1gb variant of wt88047s (which Google considers it to be a low ram device) (NO ETAs)

    3) LTR553/Liteon Sensors
    Receiving some reports on it not working on latest build, need more confirmation since I merged this patch before latest build even though it has been reported working for others. Mixed response, quite confused.

    4) Yamaha 537 Magnetic Sensor
    It should be working since there are no more reports of it working after the latest build with the same patch above.

    5) VoLTE
    VoLTE is supported but... it really drains the battery. I tried debugging it a while ago but I have no idea why it is doing so even though the services start of right. Will come back to it when I am free again. (NO ETAs)

    This are the latest developments of LineageOS 14.1 for wt88047. I hope this would clarify certain things. At the same time, I seek everyone's cooperation to not spam this thread with ETAs as well as VoLTE. Thanks :fingers-crossed:
