Over the past few days it seems randomly my WiFi goes off and it won't reconnect even though I turn WiFi on and off.
A restart of the phone sorts the issue however it is slightly annoying when this happens.
Has anyone got this issue and is there a fix?

Same here. Turning wifi off and on helps for me, however. Nevertheless annoying.

Coming from a clean install. I have been using this Rom for a week now.

I would personnally not call it "stable" because PHONE and CAMERA are very buggy !

Everybody's mileage varies and so do use cases, devices and installation profiles. However, just complaining about general "bugginess" and using a bold font will not get you anywhere. At the very least you should provide more details about the concrete issues you experienced. If you can, provide crash logs.

FWIW, besides a longer camera startup time compared to stock neither the camera nor the phone have failed on me yet. I have seen many custom ROMs and this one certainly ranks absolutely top shelf in terms of reliability.

Hello xrad,

The camera sometimes stays on a black screen when I open it. Only solution to make it work again is a reboot.
Or sometimes I've an image but I can't take the shot or even record.
Finally, the camera sometimes react badly with various play store apps.
Sometimes it works flawlessly, sometimes not.

About the Phone App, since I installed the Rom, I've noticed people complaining about hearing themself in a echo. In Speaker-mode, this echo would make the conversation impossible for them. So my guess is that the cancelling mic is not working properlly.

Cheers

This is a known issue, the echo cancellation is broken because the binary library from Samsung doesn't work on recent Lineage versions. This is not listed under "Not Working" for reasons.

As many users you have to find out for yourself, or notice that every other question or bug report in the support group is about this issue. Please do notice that this not a bug, it simply doesn't work and it's not listed under "Working" - plus the rom is free, so please stop complaining, will you?

I still would humbly request to list this under release notes, would have saved me a lot of time. Surely this isn't because non-zero "Not Working" issues would result in less wide distribution?

Let's not be too hard on him. I think he just tried to follow the advice and give some more details about the issues he experienced.

Adding this to the list of known issues definitely seems like a good idea.

This bug has been present since day one on this rom(and possibly others) and is unlikely to be permanently fixed, sometimes a build makes it far worse but it's always present.

Indeed it is, because that's the one major "Not Working" issue of LOS vs. Samsung-ish roms like Floyd...

... what's worse, because it's major _and_ unlisted I thought 'It has to be me or a problem just on my phone' when I was running LOS.

Concerning the camera: I use this ROM for quite some time and yes, for me for the first time, the current build gives not only Wifi connection problems, but also the camera is unreliable (sudden access errors / black screen).

    While these builds should be a lot more stable than previous ones they are still pre rebase builds which are on their way i just finished up kernel and i dont want any regression from previous builds when switching to new ones so they are taking a bit longer than expected but they are on their way

    Big thanks to everyone who supported this project as i do this in my free time and those help me offset build server cost and coffee :p
