Hi,

On lineage 16, I apply both patches and the echo is no more there in speaker mode, but the sound is still way too loud (and cracking) without speaker enabled. So i switched back to Carbon rom 6.1 where the sound volume is correct when calling without speaker and changed in build.prop:

audio.fluence.speaker=false

This solve the echo with the speaker mode during call (their seems to be a small echo without speaker mode, but it's largely usable)

Thanks for all those investigations on sound problems on this phone :good:
[Xperia Z3 Compact Original Android Development] Mr.Tom_Tom:
To my knowledge, the props are correctly set by this ROM, and if everything else works well, you should not need to change anything. The correct props should be:

ro.vendor.audio.sdk.fluencetype=fluence
persist.vendor.audio.fluence.audiorec=true
persist.vendor.audio.fluence.speaker=true
persist.vendor.audio.fluence.voicecall=true
persist.vendor.audio.fluence.voicerec=false

Basically this enables the noise cancellation feature called "Fluence" on the Snapdragon SOC.

The important lines then are "voicecall=true" to enable it for voice calls and then "speaker=true" to enable it in speaker mode during voice calls.

For those of you who like to play around with this feature please note that there was a change in the HAL, see this and therefore see this. This means, that the old properties like e.g. persist.audio.fluence.voicecall=true do not work anymore and have no effect. Note that by default fluence is off. So, if you use the old properties they are simply not found by the HAL and then it stays disabled.

From my opinion, the right solution to solve the echo issues would be to look for the root cause why the in call volume is still so high. Anybody has an idea? I would also be glad if anybody has insight in the audio calibration files (part of the vendor blobs) and could explain what they are doing and maybe how they are related to that.
[Xperia Z3 Compact Original Android Development] craftyguy:
Well, except it's not, and setting the properties to those values does not help with the 1) incredibly loud in-call volume, 2) very poor audio quality in-call (voices are very static-y), 3) echoing on other phone.

Thanks for clarifying the usage of "persist.audio" vs "persist.vendor.audio".

Something else is wrong with this device/ROM. Maybe it's something crazy issues in mixer_paths.xml since we've basically exhausted every possible combination of *audio* build.prop values?
[Xperia Z3 Compact Original Android Development] chopitol:
Hi. It makes about two updates, when I play an audio in whatsapp or telegram, the screen turns black. I deleted everything and installed everything again and the same thing still happens to me.

sorry for my bad English
[Xperia Z3 Compact Original Android Development] Mr.Tom_Tom:
Most likely this is related to a malfunctioning proximity sensor, nothing related to the ROM. Sometimes this happens if the display gets detached from the frame.
[Xperia Z3 Compact Original Android Development] chopitol:
Thanks a lot. when I read your answer I looked at the cell phone and indeed; I was up a little. push that part of the screen and it works perfect

thank you very very much

[MENTION=8746471]NeoArian[/MENTION], could you add FAQ in this xda post and LineageOS wiki with information, how to solve mysterious twrp problems? I saw people asking everywhere for a solution: on reddit, in this thread or in new posts on z3c section on xda. The solution is very simple: just download flashtool from sony aka Emma from here and flash the latest firmware. Then flash recovery and LineageOS and everything should work. It will in future prevent people from constantly asking about it in this thread.

Thanks
[Xperia Z3 Compact Original Android Development] DaveyJC:
Hi guys, the following settings don't make echo on the other caller on my father's Z3C with CarbonROM 6.1 (Android 8.1). The call volume also seems correct in CR 6.1:

[IMG="anc"]https://i.ibb.co/jz6HSLT/anc.jpg[/IMG]

As Mr. Tom Tom says, the name of these settings changed in Android Pie (9.0), so I'm not sure about the correct naming in LOS 16.0.

Furthermore, any solution for the high call volumen in LOS 16.0 for my Z3C?
[Xperia Z3 Compact Original Android Development] migsun:
I need a hint. my fresh installed lineageos has no OTG support.

The mobile does not recognize an USB stick, either directly or via an OTG cable.

The same memory sticks work perfectly on another Z3C with stock rom.

Reflashing without success - same behavior, no reacting when stick insert or no access with a file manager.

Any idea? Thx!

HotSpot problem with 26/12/2019 build. Can't activate it. Anyone else?

Edit:

Hotspot is working with 28/12/2019 build, but only in the 2,4 GHz band. My last build was from 11/12/2019, Hotspot was working in both bands, 5 GHz and 2,4 GHz.
[Xperia Z3 Compact Original Android Development] Alizad00:
i dont know if its only for me or not (cause i isntalled some magisk modules for mic fix )

but when in call volumes too high if you enable speaker mode you can lower the voulme much more its like they swapped when speaker s on sounds coming through earphone and vice versa

sorry for bad english

I cannot confirm that issue. I just tested the 28Dec build with an 8GB USB key and it works fine.
[Xperia Z3 Compact Original Android Development] migsun:
Thx for your info. Mmmmh.... I wiped the phone again and reinstall one more time - without any success.

Maybe my phone is broken. I havn't OTG support in recovery tool too. ?!
[Xperia Z3 Compact Original Android Development] pawloland:
You could have first try reformatting your usb stick.

[Xperia Z3 Compact Original Android Development] tomKater:
Hello Everybody,

I use this rom with my Z3c every day. Still two problems annoying :

- Very loud call and high volume when we take a call on the phone. Only one solution : play with volume level before start to speak. Not very pratical.

- When the phone is connected in bluetooth and when I receive a call, I cannot hear the caller. No problem when it's me making a call.

Others people have these kinds of issue ?
[Xperia Z3 Compact Original Android Development] anton472:
I join the question. The same problem. In the settings, the sound of the spoken speaker is at a minimum, and when you call or answer a call, the volume sliders are at a minimum, and yells at a maximum. We press the rocker down - the scroll engines and so below and the volume does not change. Move the sound to the maximum - the volume does not change. Then we move down - and lo and behold! the sound decreases. And so every time the engines call at a minimum, and the speaker yells at full (regardless of settings).

Did anyone try to install swipe up gestures (could be found on crdroid or rr). I don't know where to get it but I really care about them - Z3C has really small screen and it is useful. E.g. I use tested them on xz1c and for now I don't want to use any other navigation way ;) Android 10 gestures are hmm... just OK and works just with one launcher, I really like Xperia 11.3.A.0.17 launcher and don't want to use other.
[Xperia Z3 Compact Original Android Development] chillma:
I switched to LOS16. As a 'local' WIFI phone for music, surfing, sport and podcast... I'm very happy. The 3.5mm jack is broken so I'm using Bluetooth headphones and speakers. No problems with NFC while activating or anything else with the sound quality. Maybe I'll get a new Z3C with a working 3.5mm jack now :)

Thanks a lot Arian and everyone involved.

[Xperia Z3 Compact Original Android Development] steigerth:
static noise, annoying crackling

First of all many thanks for this excellent rom and all the hard work that has been put into it. I really appreciate the hard work and I am very happy with it. I just have problems with a static noise or a very loud crackling while making phone calls.

The loudspeaker for the ear (I put the phone on my ear) is very loud but I could adjust that with the volume control. But I hear all the time a static noise. If I use the official lineage os dialer (phone call by sim card) it is a bit better. If the person on the other end is silent the crackling noise is not to hear or only a bit.

If I use a sip client like ZoiPer the problem is more severe. The crackling, static noise is permanently to hear and very annoying. I suspect that the phone dialer is using a kind of noise cancelling while the sip client cannot use this feature.

Does anybody know how to fix that?

Upgrading from LineageOS 14.1

Hi Folks!

Thank you very much for all your work and efforts to keep the Sony Xperia Z3 Tablet Compact up to date!

I'm currently running LineageOS version 14.1 on my LTE tablet but the poor battery management made me looking for an update what led me to your thread.

My issue:

After having flashed the recommended TWRP version, I cannot manage to boot into TWRP!

My computer:

me@mymint:~$ cat /etc/os-release
NAME="Linux Mint"
VERSION="19.1 (Tessa)"
ID=linuxmint
ID_LIKE=ubuntu
PRETTY_NAME="Linux Mint 19.1"
VERSION_ID="19.1"

Installed packages:

android-tools-adb android-tools-fastboot

My tablet:

Sony Xperia Z3 Compact Tablet with LTE

OS: LineageOS 14.1-20170728-UNOFFICIAL-Lowtraxx-scorpion

Build number: lineage_scorpion-userdebug 7.1.2 NJH47D b33367a65f test-keys

Android-Version: 7.1.2

Developer Options enabled:

- Extended Reboot: check

- Android debugging: check

- Debugging notification: check

- Local terminal: check

- Confirm Apps via USB: check

What have I done, so far:

1) Downloaded recommended TWRP version twrp-3.3.1-0.4-z3c.img to my computer

2) Renamed it to twrp.img

3) Connected tablet to computer pressing the volume down button on the tablet

4) Tablet shows blue LED: OK!

5) Started terminal, ran command:

me@mymint:~$ sudo fastboot flash recovery twrp.img
target didn't report max-download-size
sending 'recovery' (13262 KB)...
OKAY [ 0.419s]
writing 'recovery'...
OKAY [ 0.892s]
finished. total time: 1.311s

My assumption: Flashing succeeded!

Now whenever I try to boot into recovery mode in order to start TWRP, the LED turns orange but TWRP will never show up. I tried it turning off the tablet, then turning it on pressing the volume up button, tried it also with the volume down button. Finally I tried to reboot into recovery using the respective option in the extended reboot menu when the OS is running.

Did I miss sth.?

Thank you very much!

Hi,

I experienced strange bug with camera. It became black... Everything was ok when I was on previous builds. (in fact I had made a backup and tested LOS17 and carbon but finally back to this rom)

Edit: I checked and now I know sometimes that's hardware problem... I'll definitely flash stock and check what kind of problem is it. Hardware or software.
[Xperia Z3 Compact Original Android Development] onestepb:
confirm

i can confirm that problem: while making phone calls an static, annoying noise is hearable in the background. it disappears when switching to loud speaker or when the person on the other end is quite. i won't call it a crackling noise, it sounds more like using a walky-talkie or like listening to an analog radio channel with a low signal.

Hello NeoArian,

There is a critical Bluetooth vulnerability:

https://insinuator.net/2020/02/critical-bluetooth-vulnerability-in-android-cve-2020-0022/

Could you please update this ROM with the latest Google Security update patch (February) as this vulnerability has been corrected?

Many thanks in advance!

Note: this vulnerability is not exploitable in Android 10 but result in a crash of the Bluetooth daemon (this could cause some inconveniences)
[Xperia Z3 Compact Original Android Development] NeoArian:
Hi, the February patch will be merged into lineage-16.0 soon. Since the builds are running on the lineage server I can include the February patch before it is merged into lineage-16.0.

But anyway, it should not take more then 2-3 more days.

Greetings, Arian

Can anyone help me? I completely wipe the phone,I try to flash the ROM, then I flash GAPPS, the animation comes, after some minutes the phone reboots to TWRP, even without GAPPS. Am I doing anything wrong?
[Xperia Z3 Compact Original Android Development] Klaus N.:
Just to be sure: Have you formatted the data partition before flashing LineageOS (In TWRP > wipe > format data) ? It's important to get rid of the stock data encryption...

Hi NeoArian,

Just saw your latest commit fixing the typo in the filename. Must have been the most frustrating bug hunt ever, single character mistakes are so hard to find! Does this fix our sound distortion issues?

Cheers and thanks for your persistence!
[Xperia Z3 Compact Original Android Development] NeoArian:
Yes, this seems to fix the audio problems. [MENTION=838709]Mr.Tom_Tom[/MENTION] found the actual typo in the end, so all thanks go to him :D

Together with two other changes, first add the stock dmic acdb id's which should bring the stock fluence configuration in handset mode and second disabling fluence in speaker mode, that should also get the speaker experience inline with stock. However it is not 100% similar to stock yet I think, sometimes I still have an echo on the other end when in speaker mode. But all in all its a huge improvement I think.

I solved the problems by flashing the TWRP in the first post. Thx ;).

Main cam issue

After some end of January of start of February Main camera stopped working. Front camera is still working well.

Could you please assist me with this issue?
[Xperia Z3 Compact Original Android Development] pawloland:
For me both of them work. Try cleaning data of camera app. If it doesn't help make twrp backup (if you want) and flash stock android 6 using emma. If the camera doesn't work on stock it is hardware issue.
[Xperia Z3 Compact Original Android Development] NeoArian:
Hi,

First of all thanks for the detailed feedback, I appreciate it.

About the audio stuff, I think it should be comparable to stock, we are pretty much using the stock setup of the mixer settings. I will hear again when I flash stock next time though to make sure. I did not enable Miracast for the Sony msm8974 devices because I don't consider it as really working, I didn't get the heavy wlan speed drop during it fixed. All TV's shown in settings should be available through Google cast which works good on my Z3C and Sony android TV, will also confirm that again within the next days. I don't think your windows laptop is using Google cast though, do you still stream from the settings -> connected devices -> connection settings -> stream?

What you describe sounds similar to Miracast but that one shouldn't be available in the official build, weird?

FM radio was working okay for me last time I checked. I will downgrade to 16.0 to confirm that in the official builds.

About twrp I have some good news :D

I don't really know about your first problem with zip signature verification, it might be caused by the official builds that are signed with custom created keys.

I have built a new TWRP with OTA updates fixed. [MENTION=8036586]115ek[/MENTION] has shared the fix. I will release it within the next days somewhere. Until now you can download it from here: https://drive.google.com/file/d/12f7WrbpkqmSMC1p3OSfRwG7k2BwlmgWt/view?usp=drivesdk

( For Z3 friends: https://drive.google.com/file/d/12eYhVT6-nFGuIlbSiDVEMnODcBUDcMcq/view?usp=drivesdk).

About the wrong time, there was a problem in the Sony timekeep service, many thanks to MarijnS95 who fixed the problem and helped me out really quick. (https://github.com/sonyxperiadev/timekeep/issues/23)

I will try to get this fix merged into LineageOS soon. Then the time will be working fine in TWRP, I already have it fixed on my device. I didn't see "Can't mount storage." On my device. Can you see if that still happens with the new TWRP build?

Greetings, Arian.
