Thank you very much. The voice is much better .... But there is still an echo problem ... both as with and without the oneplus files. By calling a person, the speaker can hear his reflective voice. This is not only in my model. Tested on 3 Lenovo k920 and everyone has the same problem.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] underr.t:
Can confirm the echo issue.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] mikely2510:
With latest update,battery is draining a bit faster when idle.

Forgot to mention before,does anyone have 4G working? I can confirm H+ is working,but LTE not. CN version.

Only one rom where i got LTE working is on Linerty 4.4 and 5.0.2 Vibe UI.

I can confirm that the Call echo is again not fixed :/
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
Frantisheq in every version unfortunately is an echo problem. Only that in the version with oneplus the conversation is much more loud.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] mikely2510:
version before last was perfect,no echo at all,i personally checked it.

Can not insert audio files from lineage os 14.1? Everything worked beautiful there.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
they are on github, i'll make new build with those
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
Github? If it were possible, I would be very happy. I am very happy with this rom. Thank you for the work you put into it.

In downloading link, there is not Lineage 16 version. When will it be back?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
when i build one, it's failing and i don't know why
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
Did you manage to do something with this?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
I think you've got enough of me? ? If nothing can be done, it is difficult to say ... We will be back to version 14
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Kroeber:
dont stress the dev, and telling you how many times you need to translate about the echo? if you want to go back to version 14 go ahead. try to build on your own and will see if you can fix the echo something you mention.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
i can't make new build because of error which is telling me nothing. also there have been no change regarding audio files between cm-14.1 and los-15.+ except .conf to .xml conversion, all values are the same and yet something has changed because echo is not the only problem.

call volume adjustment must have stopped working at that time too, that's why call volume was low and i had to hard code max value.

only difference i have noticed is in audio amplifier source but that thing is used only for lower speaker so i'm out of ideas.

there is an app which can extract some values needed from audio hal, if i can get it to work on stock rom maybe i will be able to regenerate config files with stock values but i'm afraid it won't work or there will be no difference.

camera, it is broken i know but first i want to fix audio. then there's also NFC not working, bluetooth crippling wifi,... i know about all of this and if i fix something i'll notice you.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
Ok. In that case, for such a warm word and hope that something will be fixed, it is at Lineage os 16. I like this system very much ... It is much faster than its predecessors. Thanks!
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
i am sure the smoothness of UI can be improved but only god knows the correct values to do so. if it can be smooth on snapdragon 4xx series it must work on 800 too. except Now and Pixel launchers, those bastards need snapdragon 855 i guess
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
And how are the works on the new compilation going?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] underr.t:
Mate, take it easy. It'll be done when it's done. And you'll get a notification at that time.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
I'm calm. ?

why dont you go back at version 14? your not a boss here your just a new guy wants to feeds your phone
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
new build uploading. looks like wifi is finally at full speed with bluetooth turned on.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Kroeber:
im good with new update, trabuchet work but pixel launcher wont. camera error still there when you press scan and paranoma youll got black screen so you need to restart your phone for camera work again. wifi seems good for me and for games still no problem.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Dodnikov:
Camera black screen

Facebook crash
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Kroeber:
for me facebook is okay, even in facebook video.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
Kroeber, I'm not going back to 14 because this version is much better. Maybe he has a few mistakes but I'm well aware that this is not an official version yet, and at least he wants to help in some way ..... At least I am talking about some mistakes when I find them. I am very grateful to everyone who created this project and dedicate their private time to do something for others. Please do not treat me like an enemy. Thank you very much!
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Kroeber:
well your not helping coz your being bossy.

All seems good on last update,only echo problem is still present. Ty very much for your time.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
that damn echo, i was f*** with it until 4 AM to get values from stock ROM and still nothing. i was afraid sound will vompletely stop working :D oh well, back to work. camera is sometimes black for me too.

anyone tried if voip works? skype, hangouts call,...
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
don't update, camera will be gone
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] mikely2510:
It was just good with one version,but when you removed acdb files i guess?? It went to broken again :D front camera is working,back camera is not working at all. :)
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
well... you can try to download https://github.com/YumeMichi/device...e-16.0-sultan/audio/acdb/MTP_Handset_cal.acdb

and then

adb root

adb remount

adb push MTP_Handset_cal.acdb /vendor/etc/acdbdata/MTP/MTP_Handset_cal.acdb

it will replace acdb file with the one for oneplus x, just reinstall lineage zip if something goes wrong but there's no need to worry.

the same can be done for all acdb files from

https://github.com/YumeMichi/device_oneplus_onyx/tree/lineage-16.0-sultan/audio/acdb
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] mikely2510:
Thank you vm i will try when i get to home.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
try only handset file at first and if there will be echo replace all files. don't forget to reboot after pushing file to phone. if you're on linux you can do

adb reboot && adb logcat | grep audio

you'll see how sound gets configured. or not :)
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] mikely2510:

[MENTION=7755103]mikely2510[/MENTION] i forgot, i'll replace those files in next OTA. you can still try to do it while in twrp just mount system and vendor first

looking at other devices i'm just wondering what some guys are capable of. they are using disassemblers to edit old files from stock roms :D hope we won't need it to get everything working

[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
can someone manually download OTA in settings and check that echo? it was built yesterday so it won't be offered automatically.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
There is an echo problem. I downloaded the updates manually .... It has been updated but the problem still exists.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] slavislavi:
Yes. Echo is present in 0122build
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
In addition, there was another conversation during the conversation that I still hear a strange sound in my loudspeaker every 30 seconds ... Such a quilting. Applauses often turn off. Snapchat, YouTube or they load for a long time without bringing the effect of loading.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] mikely2510:

[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] mikely2510:
i don`t,but few apps are crashing,games stablity is 10/10,but facebook,messenger,sometimes instagram keeps crashing... after almost every update i wipe cache in twrp,and i would recommend for you all to do it.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
How are the works going?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
new build will have NFC working, but the driver is not 100% stable yet.

i have changed lcd density to stock value of 640, maybe it will improve performance. you can still make everything smaller in display settings.

reverted some thermal control changes, i'm not sure yet but i think it was causing random reboots. need more testing.

also, echo... once again i have replaced acdb files with those from oneplus so check if echo is still there
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
Thank you very much! I am very happy that there is someone like you and creates this great project. Thanks!
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :

[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
No problem. I will wait.

Update only 214 MB?

---------- Post added at 11:59 PM ---------- Previous post was at 11:58 PM ----------

I guess it's still dropping because MB is increasing ....
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
400MB, i'm uploading to basketbuild first and then on another server. OTA updater is checking for updates on that server but downloading from basketbuild so once you get that ota notification you can download no matter what size it reports. i did it to prevent incomplete downloads.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
At first glance, the update deleted chrome applications. NFC works steadily .... Of course, it's me. Maybe someone else will be different. As for the echo I will check in the morning and let you know.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
i don't know what's a chrome application but if it's a shortcut to website maybe it was caused by DPI change. i'll do it again because UI is even worse now
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
The echo problem continues ......
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:
Does that problem also exist on third party dialer? Like drupe
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] Dodnikov:
With the new update, the phone has become quite fast and has lag, and there is still echo
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
ok, i've had an idea. what if there was no echo not because something was working as it should but because something was wrong.

there are two microphones on this phone, i try to disable the one near the rear camera and maybe it will help.

also, there is new ota in which i was finally able to make lineage launcher smooth/fluid/not wanting to frow the phone against the wall. some apps are still slow but i have no idea if it's a result of old device, poor programming skills, stupid framework used to build some of those apps or something i did.

if there's smooth scrolling and animations in system UI, launcher and browser i believe it should be the same for tapatalk, google now or what it's called nowadays, facebook, youtube, play store,... but it's not, no matter what i did.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
It's better .... Something has changed. But you can still hear an echo. It is much smaller than before. You're going in the right direction. Good job.!
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
thanks but i did nothing yet :D

just to be sure, is it you or the other side who can hear the echo?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
Premature joy .... However, I called again and there is an echo. My mistake. Excuse me
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
Any new update yet? Something has appeared ...
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
yes, you can try echo
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:
If that's the case, using headphones also should remove the echo.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
making new build. echo may be fixed or it may be even worse. or the other side won't here you at all :D
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] mikely2510:
I think that secondary mic is making echo because speaker on ear is so loud,so camera mic is just echoing it. Echo is detected by other side,like anyone who call me hear him/herself like on repeat. I think disabling that secondary camera mic on voice calls should fix echo. At latest updates, facebook,magisk and lucky patcher were deleted but i installed them again. No problem so far. Good update,device is a bit smoother,but i use kernel auditor and i put input detected boost to 40ms and 1.9ghz instant boost,and performance of the phone is good.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
ok, try latest ota. i just tried and i can't hear any echo. if i talk to rear mic nothing can be heard on other side.

i'll increase call volume today, looks like i reverted to lower stock values while playing with echo.

camera looks good too. qr scanner app i was using in 8.1 doesn't work but other apps do, no idea what could be the problem. i'll try to binary edit some camera files to use new location for camera data but i don't believe it will fix something.

bluetooth is still fighting with wifi. just turn BT off while you're downloading to get full speed. looks like BT is crippled on all devices, everybody has turned off BLE for example
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] underr.t:
Can confirm no echo on the last night's build.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
thank you! finally!
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
Echo is still ...
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
i built two updates yesterday, i think you're still on the earlier one. manually download and update again.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] underr.t:
I talked to multiple people and asked them about echo, they all said that they can't hear any echo anymore when they talk. But only one person told me that he can hear a slight one when I talk. But that was just once..

---------- Post added at 01:50 PM ---------- Previous post was at 01:47 PM ----------

Yeah, the first one had echo. The second one (which I downloaded last night) doesn't (at least that's my experience so far).
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
it should still use both bottom and rear microphones but rear one should only filter out the noise around. i'll try to use it for camera too, maybe it will improve sound quality.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] janforman:
May I have some little question? Is DT2W working on this build???
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
no and i won't bring it back because it was causing problems with screen not turning on or it was turning it on just by holding the screen. as Electry said it probably needed new firmware and there is nothing usable. it was me who was always bothering him with DT2W functionality but it was just a bad thing to do
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
I do not know ... I even called the second phone and I can hear an echo. I think it's been up to my ears. I downloaded these 2 updates manually but nothing changed.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] lockhrt999:

Did you try third party dialer? Like drupe?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
what phone variant? ROW or CN?
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] fgv3000:
CN
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] :
ok, are there more owners of CN with echo on latest build?

all ROWs are without echo?

just want to make sure we finally found some difference between those variants.

while we're at it, i need CN owner to flash latest stock ROM,

root it with supersu because magisk won't work,

and on the PC do this:

adb root

adb pull /system cn-system

or you can copy /system folder to Downloads with some file manager that supports root and then copy it to PC like other files

this will extract all CN stock system files from phone to cn-system folder on PC.

you can then delete apps and priv-app folders in it, i don't need those.

now make a zip of that cn-system folder and upload it to google drive so i can download and compare it with ROW files we're using now.

i'd do it myself but i don't want to flash CN firmware on my ROW device and brick it.
[Lenovo Vibe Z2 Pro ROMs, Kernels, Recoveries, & Ot] underr.t:

* in twrp mount system and vendor

* on the computer run: adb push audio_platform_info.xml /vendor/etc/audio_platform_info.xml

* reboot phone and check if echo is still present

if there's still echo or some other problem with sound you can also download acdbdata.zip to your PC,

extract it and while in twrp with mounted system and vendor do this

adb push MTP_Bluetooth_cal.acdb /vendor/etc/acdbdata/MTP/MTP_Bluetooth_cal.acdb

adb push MTP_General_cal.acdb /vendor/etc/acdbdata/MTP/MTP_General_cal.acdb

I'm sorry, I have broked the machine，when I root. But I successfully installed magisk in version 0122 with that recovery you gived me. In China, there are less people still insist on using k920, and I have talked with them. They think Vibe 2.5 or Mokee is enough.Thank you to let it use CM, Linage and RR. I've used all of these, when K920 is almost forgotten in China. I also thank you for your contribution to this mobile phone. :o
