Dear developer
thank your for your brilliant ROM and also your hard working.
I installed this ROM two weeks ago and every thing is working fine.BUT!!
recently, i've found some problem which might be fixed by your code review.
1-. when I call someone and after answer, switch to speaker , Nothing happen and the speaker doesn't works.
2- when the phone rings and I answer the call, sometimes call end unexpectedly without any reason ( I dont have logcat for this)
the attached logcat is for the first problem which hope to fixed it in your next release.
thank you for your hard working and I will support your project!!

I can confirm these issues as well. And random reboots (which I've read can be fixed with formatting sd to FAT32, but I've got too much data on it and nowhere to copy it to). And after a random amount of idle time all pps will freeze upon opening (though quitting them works fine) until a manual reboot. I was having call hangup issues with my previous ROM as well, Havoc OS.

Hi, I tried to update via full wipe to LOS18.1 from ivan on my SM-G930F with baseband G930FXXU4ESB1. But I can't get the phone to connect to any WLAN - tried to disable 5Ghz on access point, but still doesn't help - with the LOS17 from Ivan everything works as expected? Any ideas? Thanks

Are you trying to connect to a wifi network which uses combined WPA2 and WPA3 encryption? I also had issues connecting to wifi and this was the reason for me. If possible, change the encryption to WPA2 only and your issue should be resolved. I didn't use the LineageOS 17 version of this ROM, so I can't tell if this issue existed before or not.

Yes indeed my hotspot has combined WPA3+2 enabled - i'll give it a try. Thanks for you quick support.
@Ivan_Meler: As WPA3 is not an issue in LOS17 and one in LOS18 - i guess it's not a baseband/radio issue?

Samsung Galaxy S7 Edge
2 bugs @Ivan_Meler

1. before i reached the end of the install-process, i got severals softreboots without a simcard (about 5 - 8 times)

2. i got a lot of errors all the time (flooding). probably a kernel issue.

for example:
[3:dhd_rpm_state_t: 2367] exynos-pcie 15660000.pcie0: phy clk enable, ret value = 0

log attached

device g930f, clean install

edit:

3. bug

debugging must be activated, else log will be flodded by:

*failed to connect to jdwp control socket: Connection refused

Hey. Thx for a good work :)

But I would go back to 17 and have small issu here.
when typing in CMD "adb reboot recovery" I get lineage recovery screen, and when trying to lunch bootloader from there just restart to LOS.
I`m doing something wrong.
Thank you.

G930F is actually herolte, there is only one way to check what your phone model really is, your bootloader (or your bootloader version).

As some people may spoof non-international model with international one, it may cause you a really hard problem if you did not make sure what model do you have.

How:

  1. Shutdown your phone. Press Volume Down + Home + Power, skip the warning by pressing Volume Up. Phone model is shown in clear, what is written there is the clear truth.
  2. Open terminal (no root needed), write:
getprop ro.bootloader

This will show your bootloader version, the first five strings are your actual phone model.

CSC, AP, {Settings >> About Phone}, etc ... are not trusted, anyone can change them.

Since you have TWRP, your phone's probably an Exynos variant, follow this guide.


Many thanks ! Sorry for late answer, I managed to update my version number by flashing a stock rom with Odin and now it works like a charm.

Maybe a silly question...

Are the settings that I previously made in the operating system (e.g. alarm clock) taken over or do they all have to be recreated when I upgrade?

Hello,

Does anyone have problems with Android Auto?
It starts correctly on the smartphone but car displays an error connecting to the device.

I tried a full wipe+reinstall of lineage 18.1 but no success.

Thanks,

Hi,

i had to download nikgapps (basic for example) AND nikgapps Android Auto Addon. Do not install Android Auto from Playstore cause it is integrated in Android 11.
Hope this helps

Thank you bomsh,

I tried to install the android auto addon. Install seems to be ok and I see Android Auto app at restart but in 2 ou 3 minutes application is automatically uninstalled.

maybe I need another nikgapps addon?

thanks.

i just installed nikgapps basic and nigapps android auto addon.
I think GMaps, Google, Google Assistant and Google Speech (or in german Google Sprachausgabe) was installed during first start of Android Auto.

    Hello,

    I clean flash with TWRP (3.5.2_9-0) the latest 18.1 (lineage-18.1-20210407-UNOFFICIAL-herolte)

    I had echo in calls (people complained not me).
    Lowering the volume reduce it but it doesn't desappear.

    So i clean flash consecutively :
    1. lineage-18.1-20210401-microG-signed-herolte (Topic xda)
    2. lineage-17.1-20210413-microG-signed-herolte
    3. lineage-17.1-20210409-UNOFFICIAL-herolte
    Same echo in every one of them.

    So i'm back on the build i was using before : lineage-17.1-20200122-UNOFFICIAL-herolte

    I made a call with two people and they both told me the same thing.
    They hear themselves lower than in the other builds and it last only 5 - 7 seconds after that the call is completely clear.
    This may be a lead. 🕵️‍♂️

    Thank you @Ivan_Meler for the work.

    -



    Take a note that a lot of LineageOS features have not been completed yet this is not a device bug and please do not report those
    in this rom thread as you will be reported to moderator also do not post bug reports for known issues or bug reports without proper
    a) Logcat
    b) proc/last_kmsg (or proc/kmsg)
    c) data/tombstones
    d) dmesg

    Also do not under any circumstances post bug reports if you are using substratum themes or unsupported magisk modules or you have performed any system modifications



    Install gapps right after installing the rom itself dont try to boot to system before that if you want to use gapps
    NikGapps and BiTgapps were both tested and working

    I do this in my free time so bear that in mind when you notice I didn't fix known bug in next available build, Currently i work on this alone and i am not one of those kangers that just copy source and claim it as their own work,
    if you want to support the project feel free to buy me some coffee paypal.me/ivanmeler




    Feel free to join telegram group with early builds progress updates and some off topic stuff Join

    Due to requests from some users I added signature spoofing support to the rom which allows usage of MicroG
    you can simply install MinMicroG and grant it needed permissions for signature spoofing to make it work as intended
