All good to go. The Bluetooth bug is only really prevalent in pie builds. I can't remember if the issue occurred with Oreo builds.

It came up with oreo.
That’s the reason why I went back to nougat rom and still be.
Just a wild guess, maybe this bug is introduced through treble.
And because there is no Samsung rom for Oreo, there are no updated binaries and so I'm afraid there will never be a working BT for the klte after nougat :(

...do you plan a Nougat version with integrated MicroG?

I'm open to it if more than a few people want it!

Its not compatible with microg... No signature spoofing support. I tried with nanodroid, failed to patch it.

As you can see at my post and the quote of that helpful dev haoyangw
it's a matter of how many user request an "integrated MicroG version" based on Nougat.

Many of the manual solutions, like Nanodroid or Smali are causing extra problems!
Have a look also here:

The only trouble free solution for Nougat is an integrated MicroG version"! :fingers-crossed:

However, for those users on Pie a solution is here:
but that project has stopped for Nougat and will stopp for Pie as well, as soon the official Lineage support has ended.

@haoyangw the voting should be extended for MicroG. :good:

Having some issues with fingerprint unlock, which only seems to work when the device has gone to sleep by itself.
I have my recents Button set to long press to turn off screen, when I try to unlock with fingerprint it says device was manually locked and I have to input my pin, which defeats the object of fingerprint unlock
Edit : sorted it, wiped data , setup again
Sorry for cluttering the place up with a post before trying to fix it

Does anyone know if there is a way to switch the display to grayscale or to use a feature like smart pixel? I've used both features before in one of the resurrection remix roms to save battery

You could try OLED Saver. Just installed this rom and that app helps.

What I want to know is..how to change it so I can swipe up to go home from the recents menu. Hate the home button on the S5.

in shell:
echo "2" > /sys/devices/virtual/mdnie/mdni/accessibility

I do it with tasker when device battery reaches 5%

A little OT if anyone is still here - too many texts

I connect my phone to my PC and dl texts, so that I can send and receive from the PC, the problem is that I've something like 750 texts that I cannot find nor have any knowledge of.
How the H**L do I find them and deal with them?

MANY thanks

    LineageOS 14.1 with full Substratum support and -O3 optimizations

    Why another Nougat ROM? And in 2019?
    Because this project has different goals, and hence naturally it is different from other Nougat ROMs! Here are its goals:
    -Optimizations! I will try to include optimizations on both ROM and kernel side that most current ROMs don't use. That does mean possibly more bugs!
    -Full Substratum support on LOS! Because I like LOS for its stability and simplicity, but I also miss Substratum
    -Frequent security updates! I will aim to release at least one update every month containing the latest security patch and kernel fixes from LOS upstream, and whenever major security vulnerabilities occur

    -Built with latest Linaro toolchain GCC 7.4.1 snapshot and SDClang 6.0.9
    -O3 GCC optimizations applied on ROM, O2 on Kernel
    -Graphite optimizations applied on ROM
    -Substratum/OMS commits fully merged from LineageOMS, including rootless mode
    -Latest monthly security patches(Aug 2019)
    -SELinux in Enforcing Mode​

    Upcoming features​

    -September security patch
    -Random drivers backported from Linux mainline(credits to @arter97 for the idea)
    -vnswap(on a separate kernel)
    -F2FS backport from Linux mainline
    -Microimprovements in kernel logic​

    -You tell me​

    Optimized LOS 14.1 builds​


    How to install​
    1. In TWRP, select Wipe, and choose Data, Cache and System
    2. Install ROM zip
    3. Install Gapps zip(optional)
    4. Install any mods(optional)​

    Alright another release is finally here! I am very sorry for the very long delay, I really couldn't find time earlier :( Download it here.
    -Updated to the latest security patch(Aug 5 2019 at the moment)
    -Fix several warnings on the kernel side(thanks to @pascua28 for most of the fixes)
    -Upstream changes for the past 2 months(did a repo sync yesterday)
    Have already tested it like usual, everything works! Also tried flashing Intelli Kernel on top, works too :) But if there are any issues, do let me know. Happy flashing!
    PS: Sorry about the other klte variant users, I'm still planning to release the ROM for the other variants. I wish to incorporate some changes into the kernel first though. Then I'll definitely work on the other variants :) Of course, I'll incorporate any changes into other variants as well
    Good news btw! I have successfully figured out the cause of the sim card and random reboot issues in the latest release, expect a new build today or tomorrow with everything working! Will not be incorporating July security update though, haven't found time to clean up my source tree, if I do a repo sync now I'm gonna lose all my changes which took hours D: I'm working on it though, I promise!
    Finally got a successful build! I've tested it, sim card works and so does everything else! Download it here. Changes since 240619 build(0807 build is ignored because it is problematic):
    -Compiled using latest Linaro GCC 7.4 snapshot(compared to Uber GCC 4.9 in 240619)
    -SDClang 6.0.2 enabled
    -Kernel compiled using -O2 instead of -O3 for stability(fixes sim card issue, not sure why). Based on my testing and benchmark results online, the difference is negligible
    Note that the security patch is still 5 June 2019 as I have not found time to do a repo sync sorry. Will intend to update to August security patch the next build!
    -First build
    -Compiled using Uber GCC 4.9
    -Compiled ROM with -O3 optimizations
    -Merged proper OMS/Substratum support, including rootless mode

    -Compiled using latest Linaro GCC 7.4 snapshot
    -SDClang 6.0.2 enabled
    -Kernel compiled using -O2 instead of -O3 for stability. Based on my testing and benchmark results online, the difference is negligible

    -Update to latest security patch(Aug 5 2019)
    -Fix several warnings thrown by GCC 7.4
    -Sync LOS and AOSP upstream changes since June(through repo sync)
