Simple answer: No.

There are numerous things that are not working. The LED frequently stops to work. As well as Bluetooth and WiFi. The phone also frequently executes spontaneous reboots when any camera app saves a video to the external sdcard.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] mbecroft:
I have the same issue.

Specifically:

- On speakerphone, the remote party hears their voice echo very loudly (as loud as normal speech)

- On handset, the remote party hears an echo but it is relatively low in volume

- On an external bluetooth headset, there are no problems, everything works perfectly.

I wish someone could look into this - it's the only real problem I seem to have with this ROM. When OP said basically everything works, I did not expect this!

Is there anything I can tweak that might help?

Cheers

I tried this fix, it is NOT cancelling the echo problem but it makes it better. i.e. the echo is less loud at the communication partner. Disadvantage: Now I have sometimes glitches (short laud noise) when I speak and also a minor echo :-(.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] .Michael.:
That is exactly the problem with this ROM and several users (also me) tried to convince Ivan_Meler to change its statement in the initial post but he is not reacting to such complains (maybe because for most users the ROM is OK and the others are not important for him).

If someone can provide a working echo and LED fix: I offer 25 EUR (and if other users would do the same then the incentive increases).
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mint Julep:
Man seriously, the echo problem have been discussed so many time : dev can't do **** about it because. Developping an anti echo from scratch would cost a lot more than 25€ just to solve a minor issue (because if the echo bother you this much, lower the volume or use a headset.)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] .Michael.:
If all communication partners complain about the call quality then it is a minor issue, really? I also said "... if other users would do the same then the incentive increases".
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mint Julep:
I repeat : lower the volume or use a headset. And even if it's not very pleasant, no, I don't think it's a major issue. Depends on your usage, I personnaly don't call that much.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] .Michael.:
I agree that we disagree.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] bubbleman06 Philippines:
does the echo isse only applicable to stock phone app? or even viber & telegram calls?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mint Julep:
It's an issue with noise cancellation. The microphone and the speakerphone are very close on s7 so if you don't have a post treatment of the sound, basically, the mic capture the sound from the speakerphone ans people ear themself.

Some app may have an included noise cancellation system but I don't know wich one does and wich one don't.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] mbecroft:
It's important to note there are 3 distinct scenarios where echo issues may/may not arise:

1. Talking on handset

2. Talking on speaker-phone

3. Talking on BT headset

Also, in all cases, any echo is only heard by the remote party; the audio on the S7 is perfect.

I had totally unacceptable ridiculous echo in case (2), but this was 100% resolved by the fix posted a few pages earlier in this thread which patches a system audio config file. Speakerphone functionality went from completely unusable to 100% perfect quality with that patch. After putting a case on the phone obstructing the microphones somewhat, the (2) echo returned, but much less severe than before.

Case (3) always works fine as the audio processing is done on the BT device.

So at this point, case (2) has a fix that works perfectly, and case (3) is fine, never had a problem.

This leaves case (1) talking on handset. Here, I get a definite echo, it is faint enough that it's still possible to talk, but nonetheless sounds unprofessional and is sometimes off-putting to callers.

Given how simple it was to fix case (2) with the patched audio config file (at least, simple in hindsight) I wonder if there are any tweaks that would help with case (1)?

Alternatively, what prevents using the stock kernel and qualcomm binary blobs for audio processing?

It's also unclear whether only certain variants of the phone are affected, or if others are just putting up with it as it is.

Also raises the question of how is this problem handled in LOS on other devices (Samsung or other vendors)?

Let's discuss how we can work on this, if it's possible at all.

I would chip in money to fix this, too, although obviously implementing completely new audio DSP software is not feasible.

I wish the 1st post acknowledged there are phone sound issues, rather than stating that the ROM has no known issues...then I might have thought twice about installing it. That said I really really want LineageOS if only this and a few other glitches could be fixed. I do appreciate all the work devs are doing, for free!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] .Michael.:
I don't know if your statement:

refers to the post I have linked:

but as you can read it is on my phone not doing the job and I have now an echo of my voice. At my next flashing session the fix will be no longer part of the process, i.e. I prefer the previous behavior where only the person on the other side has an issue.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] fipsy:
Has he ever responded to any question or criticism from any user here? I don't think I have read anything like that yet. And this ROM has more than just one flaw. I am particularly annoyed about the recurring Bluetooth crashes. And especially about the fact that the WiFi connection is always switched off after about 20 minutes of standby and this cannot be prevented. All these things are something that bothers me to a certain extent and where I am annoyed in retrospect that I once donated money for this project. I have some freeware projects running myself and I always answer questions from users. And every donation receives a thank you. Even if this can be quite time-consuming with several hundred donations a month.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] mbecroft:
Yes it refers to that post - which for me completely (100%) resolved speakerphone echo. I have had zero issues with echo of my own voice - it's only the other party that is affected in the all the scenarios I've tested.

Clearly, there must be some hardware version differences, or something resulting in the differing behavior...perhaps if anyone reading this thread would contribute to the thread with their specific S7 version (mine is an SM-G390F) and any other possibly relevant info...and what price audio issues they have (including no issues) then we could narrow down exactly what is going on. Tomorrow, I'll set up a Google sheet and link it from here to keep track.

Let's try and get to the bottom of this!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] mbecroft:
I hear your pain - unfortunately criticizing the developer/OP is probably not the most productive course. I think he is mainly just tracking LineageOS upstream, and not actively working on S7-specific problems.

If I have the time I will set up a ticket tracker or even just a Google doc where we can all itemize our issues and try to get a clear picture of what's going on.

Possibly some of us with development experience can then look at OP's github as compared with upstream LOS and see what we can make of it all.

I would also contribute to a tip jar, but to achieve anything we'd probably need to accumulate $500+ just to make it worthwhile for a dev to even start looking into the issues. We need to know how many people are using LOS on their S7, how many have issues, before we can decide the next step here. It would be pointless for a handful of us to contribute money for nothing.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] fipsy:
I don't do that kind of thing lightly. Before I do something like that, it must be really bad. I installed this OS for daily use a year ago because I assumed it had no bugs as described in the opening post. That it has so many fundamental errors could not be seen in the thread here at that time. What actually annoys me is the fact that I'm feeling duped, because the statement in the opening post is simply not true. Fundamental errors in the microphone, bluetooth or Wi-Fi are not irrelevant and should be named.

But enough grumbling. I would really appreciate it if someone would take it into their own hands to change something for the better!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] JerryBond:
microphone echo might be lineage os issue, it's not present in supermanOS i had installed on this phone years ago. I got this phone back from my aunt yesterday, looking to update its os, and seeing this echo problem people calling me is same on my daily driver oneplus 3 lieage os based systems, including paranoid os,...

just saying it's a fairly common problem.

still have to decide if it's from broken software or government spying xD huehuehue

anyway goodluck lads!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] mbecroft:
LOL - every piece of info helps though. So you're saying you also have audio echo problems with LOS on the oneplus? So audio echo issues with LOS are not confined to just the Galaxy S7? Would be helpful to know exactly how the issue manifests on the oneplus 3.

If this is such a widespread problem I can't imagine how it has not been addressed in LineageOS. On my fxtec Pro1, running Lineage 18.1 (android 11) it works perfectly with zero issues.

My guess is back when you used supermanOS it was running an older android and kernel, and may have been using vendor binary blobs for audio processing, which current LOS does not do - perhaps.

Thanks for your input!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chrisrevoltes:
Just for the record: I hadn't any echo issues on my S7 with Ivan's LOS 14.1 ROM.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Brisse89:
I don't use my S7 a lot for calls, and I've never gotten complaints about the echo-issue the few times I do call someone, but I've seen so many posts here that I decided to borrow a phone and call my LOS17.1 Galaxy S7 and check for myself. Sure enough, there was a loud and clear echo of my own voice. Very annoying, and not something I would put up with if I actually used the device to make calls regularly.

Thank you OP for this ROM anyway. I won't complain about the other issues as they've already been mentioned many times before.

*Actually there is one thing! In the camera app there's an option to encode videos in H265, but selecting it causes the app to crash. I assume it's because the device or the ROM doesn't actually support H265. Perhaps the option should be removed if possible? Or maybe there's a way to make it work properly?

Thanks anyway!

Edit: *Nevermind. Seems to be working in the latest build. :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] fipsy:
How exactly is the crash noticeable? When I record videos - no matter with which camera app - after the video has ended, the device performs a spontaneous cold reboot in about 80% of all cases. But only if I save the video to the external SD card. Often resulting in SD card corruption. Which then makes necessary a removal of the SD card and a repair in my Windows Computer. Because LineageOS unfortunately is unable to repair exFAT formatted SD cards. This is also very annoying.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Brisse89:
Actually, now that you asked I tried to replicate it and it's not crashing now. It's even recording videos encoded in H265. It was months since I tried last time so I guess it must have been fixed in the meantime. (y)

Haven't tried recording to SD-card, and if it's as bad as it sounds then I'm not about to try either!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Sam1314:
Is it possible to update to this ROM when having LOS 16.0 installed (https://xdaforums.com/t/lineageos-16-0-for-s7-build-30.3842465/) or does it need a clean installation?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] fipsy:
When recording to the internal sdcard there are no problems. Only when recording to external. But the space on the internal card is so small that you cannot record larger videos there - especially in high resolution.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Durchmesser:
Reading these posts about developing here get me more questions than its solve.

Could someone please explain how this Rom get developed compared to a supported LineageOS?

My opinion was that @Ivan_Meler has an S7, write some own kernel patches for missing drivers which went into the LineageOS repo and create his own ROM and If the phone quality has reached a certain Quality it gets official.

As far I read until now, it seems I misunderstood something?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] .Michael.:

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Roberto W.:
i think the problem are the los policies, they require a 100% lineage owned code to be safe for future versions. maybe that is not possible for the s7. - just my interpretation
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] fipsy:
I also think that a lot of the problems are kernel related. And it looks like nobody is able to change anything about the kernel. I believe that is the main problem.

Also wondered if Ivan is planning to do make a LineageOS 18 for Galaxy S7 or if I should slowly start looking for a new phone XD

I think this is a commonly known problem. Same issue applies to bluetooth. It is also annoying that the wifi connection is deactivated about 20 minutes after display off, so that everything then runs via mobile data. I think these are all kernel-related problems and since nobody seems to have access to the kernel, they are unlikely to be resolved.

Low call volume issue?

Is the low volume in call issue fixed in build 3?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] sponge4:
Folllowing issues (Build 3):

1a. Boot-up the phone and enter the sim-pin.

Then unlock the screen with a personal alphanumeric password, but the phone is asking for sim-pin again instead, you have to close and reopen the dialogue, then you are asked for the nurmal unlock-password. If you do not do that you see for a short time: wrong pin, x tries left.

Sim-pin was for sure correctly entered during 1st question. You also only see a num-pad for the normal pin question while when asking for sim-pin a second time, then you see the normal keyboard.

This only happens each bootup. All subsequent password-unlocks are ok.

1b. In some cases, it seems when the phone went to sleep while you are in an edit-field, then you want to unlock the phone again and then you quite often do not see the password edit-field, you only see the keyboard but login works while blindly entering the password.

2. Cannot permanently suppress caller-id in the dialer settings, it always flips back (after a few seconds of reconfiguring) to "network default".

3. Battery-Percentage missing in status bar (ok, we know)

4. Is it planned to allow an option to block wlan and mobile traffic for each app individually in the Settings -> Apps menu as I knew it from LOS 15?

5. You set a mobile data limit of xxx MB and you have alredy used yyy MB of mobile data.

Go to status-bar and the "mobile data" icon, you can expand this icon (I do not mean the press to disable mobile data) and you then see: Used data: 0Bytes, traffic warning 2GB (the default one).

Thank you!

I still have problems with 5Ghz WiFi on my G930W8 with the latest build and the previous 2 builds. As a sanity check I installed Lineage 16.0 and it works fine.

I can get it to work sometimes after rebooting the phone or changing my routers SSID but then it eventually stops working again. 2.4Ghz WiFi works fine. It's just 5Ghz that is the problem. The phone sees the SSID and other 5Ghz SSID's, it just refuses to connect. It's definitely not my router. As I said the phone connects fine running Lineage 16 and when I had stock firmware on there.
