Yes, there are monthly updates coming, but it looks to me like these are just security updates. Bug fixes no longer seem to take place.

I would like to know if the WiFi error that reproducibly occurs with me also occurs with others. For me, it always happens around 7:30 am in the morning. At this time, I synchronise a lot of data with the app "FolderSync" with Google Drive daily. And every 4-5 days, the WiFi connection drops during this synchronisation. It is reproducible and I get the message: Unable to resolve host "www.googleapis.com": No address associated with hostname. This has been the case since I started using this Release of LineageOS 17.1 on the Galaxy S7. Before that, on the S5 with LineageOS 14.1, it worked perfectly for years.

I once read out the dates on which the WiFi crash occurred:
12-21-2020, 7:41 am
12-26-2020, 7:27 am
12-31-2020, 7:05 am
01-04-2021, 7:40 am
01-08-2021, 7:24 am
01-11-2021, 7:00 am

The regularity with which this error occurs is striking! On the days not listed, by the way, the same transfer runs without any problems. The problem occurs regularly only every 3-5 days.

Edit (01-11-2021): Today the WiFi crash occurred even without a transfer. Just like that while the smartphone was on standby. It apparently has nothing to do with the data transfer.

If the connection is lost, WiFi remains on, but not a single WiFi network is found anymore, the list is empty:

If I then manually switch WiFi off and on again straight away, all access points are found instantly and the smartphone also connects to my network immediately:

Are there others who have a similar or the same problem while transferring larger amounts of data via WiFi?

The opening post of this thread still references the 12-11-2020 version. Please only comment on this version from Ivan Meler in this thread and not on others, otherwise it will be total chaos here!!!!

Some reported problems with the microphone here. I can now also confirm this. In the middle of a phone call, I switched the smartphone from one ear to the other. While I was doing this, the display went to full brightness and the microphone suddenly stopped working. I could still hear the person I was talking to, but she could no longer hear me. I had to end the conversation and call her back, then it worked again. But the automatic control of the display brightness no longer worked. I had to switch it off and on to get it to work again. I've had this happen three times now. So it is also a bug in the current release.

So there are some bugs in this release that don't always occur, but only once in a while. However, if the microphone and WiFi don't work reliably, that's a knockout criterion. Something needs to be done about this. I don't really want to have to wait for Android 18.1 to work reliably. :-/

That's right, both camera modules in the S7 are really crap. Significantly worse than the one in the S5. But if the whole thing is a hardware problem, it should occur in all Android versions. Does it do that?

I could imagine it might be a Kernel problem too. Are there any custom kernels that could be tested together with this Rom?

I don't experience any problems with the current version. No echos in calls, no interrupted calls or any problems with bluetooth-speaker or headsets, no lost WiFi-connections at all. I think, many user don't have any problems and just don't report it here - but this could be a usefull information for those, who look for a new custom ROM.
Thank you Ivan!

I don't have an echo either, but I have problems with the microphone. I think the same problems have just been reported a little too often to be ascribed to chance. If so many people have the same problem or when it occurs very regularly and frequently, it cannot be a coincidence.

    There's obviously a solution: In the APN's preferences IPv6 must not be registered. Mobile internet only works with IPv4. Eventually this helps here, as well.
    Worked here. Mobile data wasn't working. For some reason, the default was IPv4/IPv6. Switched to only IPv4. Working now!

    So coffee and donations to help cover build/development server cost are as always welcome, Enjoy new build and new and reborn S7
