Well you know that this is almost 3 years between los 17.1 and 19.1 ?

Well if all work is documantated, theoriticly it should be possible what changes was made. BUT it will take forever to find if any issue is on the rom side at all, if not everything is just for nothing. Its difficult because the dev itself isnt facing this issue so he has no device to refer. Remember he is doing it on his free time.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Jozé490:
Yes

My point here is it's not hardware related.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Robert7x:
But he also said that Architect_Kev previously reported that builds in January didn't have this problem! If that were true, it wouldn't have been that long ago...

But OK, thanks to this reference to Architect_Kev's posting, I now at least see that this was discussed quite vigorously here not too long ago...with little revealing results, just mentioned in passing....
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Robert7x:
I'm sorry, I didn't want to revisit this topic unnecessarily, I was just pleased to hear Ivan's positive news that something had been accomplished in that direction! I didn't realize he seemed to be talking about a different problem!

I'm going to say goodbye now and put my S7 back in the drawer.....

I promisse my self to stop following the further development of this otherwise brilliant software, as I and many others seem to have the wrong hardware, but this little S7 is very important to me, as such small compact devices are rarely available anymore....

It's a shame, but so what.... just unlucky again....
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] dougw_:
Since the problem is still present for some people, maybe would be relevant to share more details, such as,

Model number of your device,

Which country you're currently in,

Carrier,

Network (3g, 4g)

What type of communication was used (normal call, call using an app eg: whatsapp, signal, video calls).

If there is any assumption that different hardwares could be inducing it, at leats this would be useful data.

For people that had their problem solved with this update, sharing the data would be useful to others trying to discern successful cases.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Robert7x:
I follow this topic for years and it seems to me as if many talk past each other here!

Some think that affected users blame the developer and see themselves encouraged to intervene here protectively, although it should be clear to everyone, that without Ivan Meler, the s7 would have died long ago!

But that's not the point!

The mood here is very quickly very strongly heated up on this subject as it seems to me....

I think it's just a shame if the affected users here might be able to help solve the problem only one does not use this opportunity, because it affects not so many anyway, so you think maybe....

but as already posted so few are not at all!

again for example: https://gitlab.e.foundation/e/backlog/-/issues/503

but times to your 5 points:

Modell Number : SM-G930F

Hardwareversion: 9

And I just tested again....If I do not use the normal built-in microphone for normal phone calls, but a headset is apparently already sufficient to fix the error! Perhaps also already an acceptable solution for many users;-)

With this, some of your points like "Which country you're currently in, Carrier, Network" already tick off
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
For the people which have the problem:

Do you use gapps which replaced the stock dialer app ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Robert7x:
NO!

In my case, a freshly installed original latest Lineage Rom without Gapps or other kernels etc.

Just to test whether the echo problem has been fixed...

The device is not in daily use! No additional apps nothing! So no external sd card!

By the way....

Does anyone know if the second built-in microphone has already been deactivated by software and made available to an affected user for testing?

Since the use of a headset alone is enough for me to bypass the error, it may be related to the two microphones which are coupled differently in different models or work differently....

Covering alone does nothing in any case....
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Robert7x:
Maybe also interesting to compare the hardware version!

Mine is, as already said, version 9!

(Displayed in Lineage under the Model item in "About the device".)

What version have other Echo-affected?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
My goal was to compare if its only happen in the stock lineageOS dialer or in google dialer too

So is this happening in third party apps too ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] bixaon:
I have the same version (and echo).

Anybody who tested call from remote side and sure not having echo,

which hw version have you?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
Well im currently on PE+ plus ROM. And it says i have Version 8.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] lebon00:
Hi,

I have 2 Galaxy S7 and both of them have the echo problem.

S7 1 : SM-G930F, Canada, Telus, 4G, Normal call

S7 2 : SM-G930W8, Canada, Telus, 4G, Normal Call

The Roms working for my 2 phones are Havoc OS 3.x and FloydQ6.0

I did not try with a bluetooth earpiece.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] TheLuggageFollows:
Thank you @Ivan_Meler , very nice improvement!

In-call audio is way better, although not fully OK, yet.

- On my device, I can hear callers well now. No echo when others speak!

- Using an external BT microphone, others can hear me well without echo/tinny/robo voice!

- However, using the built-in microphone, others still hear me badly. The sound has changed, though. Whereas there was this tinny echo before, now others hear me in a slurry fashion. People described it as "You sound as if you are drunk" or "Are you eating a hot potato?". After trying it out myself with another device I can confirm the sound is different than before.

That is, the remaining issue appears to be related only to the internal mic while the major problem that was related to all in-call audio seems to be solved.

If I had to guess, I'd say that playing around with the mic gain settings could be a good angle of approach. I won't have time to play around before next week, so if anyone finds the time, I would appreciate it.

Again, really nice job @Ivan_Meler !

After installing I'm just getting arched line with pulsating curcle swiping accross it and two bottom keys either side of centre butoom flashing on and off and nothing else happening.

has any one any idea whay I have missed! I updated twrp before installing.

thanks for any help here.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chomsky55:
Looks like a bootloop. I would try flashing the ROM again.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
Do a clean install with wiping system/cache/data/dalvik-cache

Flash everything again and try if its working
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rho-bot:
Have you allowed TWRP to install its TWRP app? This is(/was) known the exactly cause this bootloop.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
I did three times in total.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
I have installed TWRP using Oden and have installed TWRP from google play an used that app to update to latest version if that is what you mean. I can boot into TWRP no probs and used it to install rom and restore other images without issue and I used the one from google to update it which I think worked ok.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
I Have [ROM][G930F/FD][ALEXNDR] * U8EUE1 * DevBase v7.4 rom installed and all was working ok for a while until I noticed really bad net speed. I am fairly new to phone roms so having everything working I just thought I could just use TWRP to install this new rom but did not wipe anything just used the install button then chose the Lineage zip file then clicked install image. so your saying I need to wipe System/cache/data/dalvik-cache before installing. does that mean I will loose my apps and settings and will have to re-install all. Ill give it a go hopefully I get out of boot loop again was tricky took ages to figure out how as i had to hold volume down, start and front button then once you feel vibration quickly switch to volume up, start and front button to get back to TWRP hope that still works lol.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chomsky55:
Do NOT install the twrp app, you don't need it and you don't want it. Just wipe everything sys/cache/data/dalvik and flash the ROM again. You can also make sure thast the ROM you downloaded is not corrupted by checking the md5sum.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
You flashed lineage os on an samsung based rom, thats why you get a boot loop. You need to wipe system/data/cache/dalvik-cache/

Unfortunately yes you will loose all your installed apps i dont knwo if wiping data will clear you internal storage. You can try it since your are not wiping your internal storage. Just make sure internal storage in unticked

Also you can try to boot in to twrp Mount as mtp and connect your phone with your pc to get access to your data and simply put it in your pc.

You always have to clean install if you are coming from samsung based rom.

Best way to enter TWRP when you have bootloop press and hold volume down and power buttom like 10 sec immediately your phone restarts (showing samsung galaxy s7 logo) press and hold power buttom+ home button + volume up
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tha_G:
Hi guys,

I messed up and deleted my /system folder by accident in TWRP.

Obviously my phone cannot boot anymore and I need to reinstall everything (when trying I get a bootloop).

But when I try to enter TWRP it is stuck on it's logo-screen (also in a bootloop).

I have reflashed TWRP to recovery via heimdall but this does not solve anything.

Anyone knows how to solve this?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
Many thanks for your help it's very much appreciated.

if i wipe system/data/cache/dalvik-cache/ and install Lineage and decide to go back can I still use my back ups in Restore in TWRP is that like a windows image where all your apps and setting are backed up with windows!.

thanks again
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
thanks for helping very much appreciated. I gather you don't mean the main TWRP app just the google store downloaded one! and i'll check the image it's not corrupt.

thanks again
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chomsky55:
I mean flash the TWRP recovery but don't install the TWRP app.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
thanks :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
Sorry but could you just clai

Sorry could you clarify one more thing! you say "flash evrything again" does that mean when i wipe system/cache/data/dalvik-cache I also loose TWRP, no-verity-opt-encrypt and magisk as well loosing rooting ability and would have to flash all again from scratch as though I'm coming from a unrooted samsung rom is that correct? or are they left still on the system! somewhere as I said I'm new to this and don't understand the directory system and not sure where those software would be stored if wiping rom partition if that is indeed what I'm actually doing here.

thanks again
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
With flash everything again i mean lieneage rom zip, gapps zip and as you whish magisk zip to get root (with twrp) You dont need dm verity zip on aosp roms. You wont loose twrp unless you flash a stock rom with stock boot img.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
Many thanks for clarifying that your diamond cheers buddy :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
Thanks to all for your input can't wait to try this rom your help is really appreciated thanks again guys your all saints. karma right back at ya :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] jahnkehe:
Still having issues with Echo, these issues are only going in one direction.

Call to the S7 / call from the S7

In both variants, an echo can only be heard towards the S7. Speaking from the S7 is without echo on both sides

The problems with distorted speech are solved.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
Hi again

after installing Lineage it seems I'm using wrong gapps as I get an error installing says unsupported android sdk version and i'm using install zip in twrp and not rebooting as I read you should install all before booting in to lineage. and I'm not using side load as i read somewhere others were doing.

can any one tell me where to get the correct version! for UK galaxy s7 sm-930f

I used this one ( BiTGApps-arm-12.0.0-R45_signed )

any help would be appreciated as there is no mention on here where to get supported gapps.

cheers
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
Hey,

Unfortunately bitgapps has only gapps for 12.0 for now.

You need one which supports 12.1 (12L)

I personally use nikgapps. This link will bring you to the right packages. Just download which package you need. You can check the diffrences bettween the package by clicking here

You need to wipe data/system/cache/dalvik-cache and than install lineage. Right after installing lineage, without rebooting install the gapps you prefer.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
Thank you so much again buddy absolute hero :) and many thanks for getting back so soon and for the links. cheers
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
It's getting phone ready as we speak :))) Gapps went in perfectly as did magisks v25

hopefully all goes well just waiting on phone at Copy apps and data screen :) cheers again buddy

All working fine a big thank you buddy :) its like a new phone lol

Hello everybody. My friend has an s7 flat. Which lineage os you recommend for an average user? Or if you suggest another rom
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] TheLuggageFollows:
SM-G930F with hardware version 9, tested on 4G normal calls in Germany
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] lebon00:
Hi,

The SM-G930W8 is hardware version 8

For the SM-G930F with HavocOS Rom no version number is shown, just that it is exynos5 (this is my daily phone so I will not reflash with LOS until echo is gone).
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
Hey master373

unfortunatley I went and messed up :( all was going well but realised I should have organised my files or back ups prior to installing lineage so tried to retore back my ALEXNDR rom. I wiped the files before restoring image as suggested like for the for lineage install but i think I have missed an important part when I had lineage running although I remembered to make a back up of lineage first but I neglected to enable usb debugging and oem unlock which I assume reverts back to off when a new os is installed!! I'm just guessing there as I have a twrp boot loop it just stays on twrp main screen. so I think it must be becaus of not enabled usb debugging and oem unlock on new lineage os which I assume you need to do that evertime you install new os ://// so again assume this is the caused of the boot loop.

any idea how i can get back to twrp and install my back up of ALEXNDR U8EUE1 DevBase v7.4 rom. I was too eager to get lineage on :/ you live and learn well hopefully that is! again any assistance here would be really appreciated I think I have to resort to Oden but not sure how to sort it from there.

I can get into download mod but trying to use twrp just hangs at main twrp screen.

thanks again if you can help.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
Hi buddy

saw the original post refresh twrp oden. not sure what Deleted means?

I'm assuming that you deleted your comment because that idea may not work if OEM unlock and usb debug are not enabled. I have been reading loads but just getting confusing as its hard to find exact issue like mine but looks like I have to flash firmware to to stock so if I have to flash firmware using oden to set it back to original rom I suupose I will loose my twrp backups of both ALEXNDR and Lineage rom installs not that I was sure if they were usable any way as I have seemed to have missed used them in some way!. am I correct in thinking that!,.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
Hey, sorry i was on my way home and didnt had time to think about it.

Well yes i think the only solution now is to go all stock and start from skretch. This will erase you internal storage(and the backups if they are not in your sd card) and data. I dont see any other option. Maybe someone else can help you if there is a solution without going completly stock.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
No worries buddy many thanks for getting back to me. yer that's what I thought. just one last question is the twrp housed on internal storage or does it reside on external sd card the actual app! I mean not just its save directory as that is where my twrp back ups are housed and can I still use them them back ups once I get a rom up and running again with new install of twrp. what I was thinking is install firmware stock rom then install ALEXNDR 's rom with twrp and root then use the back up of ALEXNDR to get my setting and apps back then do some other backs before attempting try lineage again.

of course remebering to enable OEM and debug at ever stage this time LOL
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
TWRP is installed on the phones recovery partition. Just like the stock recovery is.

The TWRP app you downloaded will be in the data partition on the phone. But i never used the twrp app. So i dont have experience with the app.

The backups you made from TWRP recovery will save normaly on internal storage. If you have the backups on your pc (or sd card) then it should be possible to use them later after going to stock and flashing twrp again. Just do a restore in TWRP.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tha_G:
For who is curious,

The only thing that worked was repartitioning all via odin and then reformatting data of course.

Lineageos is back up and running ;-)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CitizenSmith:
Just thought I would update you since you helped so much "invested time :)" and all that lol.

I managed to get back to ALEXNDR restore image my back ups worked fine which were saved on SD card I started firmware then ALEXNDR rom then restore in twrp a bit long winded but at least I'm home lol. now i can do a back up of needed files before trying lineage again. one thing I did notice when Lineage was installed was I no longer had access to Galaxy Store and other sansung apps some you can't get! and there was no apk available apart from some dodgy chinese vsersion. though not the end of the world but I had a paid theme on there I really want to keep and its now discontinued so can't get it again which sucks gonna guess I will try and see if I can lift it off android in some way and save it.

Thanks again for all your help I really have appreciated it. you certainly made the experiance a hell of a lot easier :) cheers buddy
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
Hey,

No need to thank me.

An yeah los isnt samsung based so you will loose access to some of the samsung apps and themes Unfortunately.

Glad it worked anyway. Cheers

Hold down Power+Volume Down+Home for around 7 sec until the warning screen appears. After that press volume up to continue. Now it says Downlaoding and Odin should recognise your Phone. Now You have to put the 3 files from your downloaded zip in right direction of odin.

Eg the File which starts with AP in AP.

The file which starts with BL too BL and so on.

Make sure you are not using Home CSC in CSC

Than press start and wait until it says pass.

After that all should be done. Phone should restart and erasing screen should appear.

After that you should have the phone as stock.

Make sure you are using SM-G930F latest Firmware.

After that unlock developer settings and enable oem unlock.

Flash TWRP through odin

Make sure auto reboot is unticked.

When phone is rebooting immediately press power + volume up + home buttom to boot in TWRP.

If phone is booting to stock rom, the phone will replace TWRP automaticly with stock Recovery so dont let it boot. If you manage to boot in TWRP go to wipe and than format data, type yes. Do not reboot. Go to TWRP main screen an click wipe and than advanced wipe. Choose Dalvik/ART Cache, System, Data, Internal storage, cache. Swipe to wipe. Dont reboot. Go to TWRP main screen. Press reboot and then recovery. After that press restore and select your backup files from sdcard
