Just upgraded my H990DS to the latest build directly from 19.1 (dirty flash) and wanted to say thank you to the devs for keeping us alive and also share a few things from my experience till now:

- Bluetooth is working fine (Only tested with earbuds) whereas it wasn't even turning on before on 19.1. That's great.

- Double tap to wake still doesn't always work.

-Quad DAC is working just like before where there is a delay when you turn it on or off and audio app freezes if it's running when you turn on or off.

- IR Blaster is working fine but the "Learn" function still not working, for example in the irplus app.

- Hotspot is working fine but only if "Extend compatibility" toggle is turned on. Same behavior as on 19.1

- Location service seems to be much better now. Before it would only work if I was outside but now it's working great even indoors.

- Camera seems to be working better now. I would have issues using the whatsapp camera for example where it would just freeze. But now It's working fine and the new "Simple QR" tile works great.

- Setting the display size to something smaller than default messes up the notification panel. What I mean is that the top toggle gets hidden behind the notch. I did not have this issue on 19.1. Also, I remember reading somewhere that the second screen feature is making a comeback in LOS 20. Is that confirmed for a future build?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
Good to hear on all.

Second screen - no. Not sure where ya heard that.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xfoliate:
So after further testing, i'm having issues with video recording. It freezes while recording, specially if I try to zoom or adjust anything else. I tried recording with different apps including stock and it's the same behavior. Picture works fine.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] itt533:
yes...
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Robowarrior834:
Looks like the quad dac is working a bit better with 20. On 19.1 it was glitchy and would cause audio to stop from time to time.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] loyukfai:
Yes, Google has dropped FDE in Android 13, so if you "upgrade" from LOS 19 to 20 with encrypted /data, you must wipe.

Cheers.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] neolancer07:
Glad that the Charging Control feature has been added, but it currently has problems.

The Limit charging option of Charging control, while it does disable charging, causes the various charging status visuals to go berserk when the phone is plugged in while the current battery is at or above the Limit value:

The lighting icon inside the battery icon of the status bar "blinks" between off and on.

The Battery Saver toggle in the Notification Panel constantly switches between Off and Unavailable.

On the Battery page in Settings, the status text under the large percentage and meter bar, constantly switches between "Not Charging" and "Connected, not charging"

While all of this is happening the phone becomes real hot.

v20 model is a h915 converted to h910 running the latest official build with no gapps.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] taketwicedailey:
It was mentioned in the LOS 19 thread that there was going to be a complete Quad DAC overhaul with lots of individual settings available. Is that still planned, or have I just not found these settings?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
No, it wasn't released so far, and when it will, probably should be readable on the changelogs (just the H990 as an example).

One of the devs talked more on today's new custom kernel release post
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] taketwicedailey:
Awesome, that's super exciting! Is this coming to both SwanKernel2000 and the official one?

I actually didn't know there was other kernels available, I might try it in the future.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] taketwicedailey:
I can confirm that I get the same behaviour on my h910. (with gapps)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] neolancer07:
I extensively use the Night Light feature. When enabled, it has visual issues that commonly occur when typing or moving the text cursor in dialog boxes where random elements on the screen flicker. To prevent the flickering with Night Light I found that enabling "Disable HW overlays" in the Developer options fixes the issue.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] andruyd:
Are any of you able to test bluetooth devices like Oura Ring, smartwatches, fitness trackers? Do they work?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Thor316c:
LOVE this release, totally fixed the HiFi Quad DAC issue in 19.1 where it kept shutting off! Listening to my HiFi goodness now!

Thank you again!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mmsp15:
As precaution to those who are rooted using Magisk... LOS 20 or the new kernel or something does not like the newest 26.2 of Magisk so I wouldn't recommend trying to update to it as of yet ... could just be my H910 I don't know I just know it failed 3 times to apply the update.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] AShiningRay:
It's coming to official as well, but only when we deem it stable enough to not cause other issues with audio. There's also a few rough edges to fix up.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] loyukfai:
yes, noticed that night light is broken as of now

for me otherwise solid, aside from a few random reboots on h990 when under load

btw i see from the changelog that d2tw maybe getting some fixes?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] loyukfai:
Thanks! Have been using MSG. Trying this now.

Sorry for a stupid question. How do I load the config?

Cheers.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
No problem, you just maybe tired or didn't pay enough attention, but I'm sure that won't happen next time.

According to the page on how to load you must put the file in the correct folder > and then double tap around the shutter > verify that's actually the correct file and select restore.

I didn't try to zoom during video recording (in both 1080p and 4k) using the GCam MTSL and didn't freeze at all, even I'm using a slightly tweaked conservative governor. Can you try this app and see if you'll have the same results?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xfoliate:
I just tried this app and the config file you provided. It seems to be working fine, zoom is very laggy but at least it's not crashing. But the main issue with this app is that the image quality is super grainy for some reason. Are you experiencing the same thing? Other camera apps are not grainy at all.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] itt533:
are you sure for ir blaster? before (I'm still using 18.1) it was firing and was getting stuck for some time.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] itt533:
in 18.1 it is making sound too loud and make a strange noise, like audio lossily compressed with lower bit-rate that necessary.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xfoliate:
Not sure what you mean exactly by "getting stuck". But from my experience, it works fine. There is definitely a delay between each trigger but it works. I've just never been able to make use of the Learn function.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] itt533:
can anybody test stereo and mono voice recording? I usually use 'Audio Recorder' from f-droid.org. I always need to set 'Recording Volume' to 400% but for mono recording, it does well enough. For stereo, the volume is 10 times lower. Afterwards if i normalise, e.g. with ffmpeg, the sound is not good. I modified the file /vendor/etc/mixer_path_tasha.xml following a guide in a thread which link is given in an earlier input in this thread. That doesn't seem to improve things.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] itt533:
i meant that when testing once, it would continue outputting IR rays (checked with an amplified IR receiver diode) for maybe 2min. I'm unable to say whether that output was pulsed or cw. What app do you use to test it?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dealerman13:
For me also bluetooth doesn't work with any device (when I toggle it, it cycles on and off), also fingerprint is broken (when i try to add it just says fingerprint setup timed out - without any time passing), and NFC never worked on any LOS build the sensor might be damaged.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
Which does do you have?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Since most media quality experiences (photo/video/sound) are extremely subjective and/or controversy depending on what are your parameters I'll try my best here.

My best mobile experience EVER was on my OnePlus 3 with GCam5.1.018-Arnova8G2-V1.7 (The details are sharp enough, focus was perfect, the color/light balance was perfect and no problems, just the lack of raw for further editing)

On my V20 the stock Nougat/Oreo never satisfied me, but I don't take much more pictures, so I didn't have that need to search for another GCam.

The config file that I attached isn't my creation (I just found it and worked enough) but for my taste it has still room for improvement on every way, but that takes time and right now I don't have this time available.

The MTSL+config file on ideal light conditions for me I couldn't perceive any granularity on the main rear camera. The wide lens don't have as half quality on my opinion, and the front camera I also think it's below average.

When you have less light than desirable, you may have more grainy pictures, but isn't a deal breaker so far to me, but your taste/needs may disagree with me, and that's fine.

The issue with any GCam is the lack of configuration/compatibility when the device isn't the same that was originally ported.

For video recording having the ability to choose different sound sources for itself improves the compatibility with our devices.

I tried also to modify this file strictly following the guide the and my result was no sound whatsoever. Since I didn't make a NANDroid backup or a backup of the file, I just erase all and flashed again. But I agree that this app doesn't work as it should on wither Lineage 19 or 20, and the recorded sound it's way too low compared to the stock ROM.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Usually fingerprint not working it's associated with wrong firmware version. So are you sure that you had downgraded your device to Android 7/Nougat before?

Bluetooth wasn't working on the specific H990 variant for the first build, but it was solved. I tested on my both H990DS and H990N variants with a clean install (using their on Lineage Recovery)

Are you sure that every single issue that you have isn't hardware related than software? If you have the time, please flash the Android 7 of LG stock ROM for your variant and test all those functionalities.

If it's all working fine, but when you flash Lineage following the instructions correctly and still doesn't work the way it should, please make a proper report. Here on XDA page have a good tutorial on how to do it in a way that help fix any issue.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dealerman13:
dang, guess what I installed from a rooted android oreo I didn't think it would make too much of a difference, to return to stock I thought that you needed (do you?) TWRP recovery which doesn't work with lineage, then I have to root then I have to flash LOS, idk I barely did it the first time can you say anxiety... anyway I will try
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] AShiningRay:
IR was fixed on 3.18 (and in turn LOS 18.1) as well, although that fix was kinda sneaked in right when LOS 19.1 also arrived with a better fix for IR, and also a lot more under the hood due to the new kernel.

So it's not unexpected to find a user that had IR working on 18.1.

As for the learn function... not sure if it's even something we can get working outside of stock, given the UEI blobs we're working with.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] loyukfai:
Not sure if this is related but D2TW seems to be working better now.

https://review.lineageos.org/c/LineageOS/android_vendor_qcom_opensource_power/+/365394/
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dealerman13:
Oh man I exausted myself trying to make it work, flashing the recovery didn't work at first, second try it did, did a proper flash this time fingerprint works, NFC started working, wifi and the phone in general were slow now its great (with Lspeed). Everything else works great as far as I can tell. Now for bluetooth music playback works which is an improvement however it constantly cycles on and off with my fitness tracker it doesn't even connect (Polar H10). So I guess this what this comment is about which logs should I collect (radio, driver, kernel panick, system)? Will try tommorow.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Arya_3RDNumber:
After using this ROM for a week, battery life and DAC activation far far better than LOS 19.1. About performance I feel it slightly improved, not sure tho because I only use this device for daily need and music play.

I'm using US996D variant and facing 3 minor issues (at least for me). Just want make sure if this issues are common or not.

1. About bluetooth, I seen someone facing this on H990 variant then need to clean flash to completely fix, while I came from LOS 19.1. Actually bluetooth works well, but sometimes it stopped working when paired to my Mi Band. When I tried to pair to my PC, it said "Problem connecting. Turn device off & back on" but no fix after restaring bluetooth nor device (while my Mi Band work again after bluetooth restart). Also I tried pair use my TWS and Dualsense controller for 5 hours for testing, there are no issue at all.

EDIT: After clearing data of Bluetooth via ApkManager, my Bluetooth now working normally. Seems clean install/flash ROM way more recommended because I remember when first time upgrading LOS 19.1 to first build LOS 20, my device frequently reboot suddenly almost every first time opening existed apps.

2. About display, not sure what's going on, but my display color redish than usual and changing normal when opening recent apps switch (by I mean, like color switch at app's display when opening recent apps). This was fixed when I turned on "Disable HW overlays". But I'm wondering if turning on it can affect much battery life or not. Also I seen someone has Night Light problem which need turning on "Disable HW overlays" for fix. So, is this problem device specific or platform bug?

3. About charging control. Honestly this is my first time using charging control with Limit to 90% charge method. When charged device reach 90%, it rapidly vibrate and likely connect-disconnected. Is it common like that for charging control limit method?

I'm really glad this device received official LineageOS 20 with upcoming DAC control panel. Past time I stick with stock android 8.0 because I don't want to loss DAC functionality, but I can't bear the slowness and bad battery life at stock V20 android 8.0.

Really want to say Thank You Very Much for the Devs :)

The issue with the ir driver has been fixed in 20.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Hmm, I'll see if i can replicate that behavior on my pixel watch. In the mean time, could you grab both a logcat and hci snoop log?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ar2000jp:
And the V20 lives on! Thank you for keeping the smiles on our faces. :)

It's a shame encryption had to go, though.

I'm assuming the list of people to donate to is the same as LOS 19.1, correct?

I believe it was npjohnson, AShiningRay, ROMSG, xxseva44, and the LineageOS project.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xfoliate:
So I've been trying to figure out why my phone is so laggy and just feels unstable, I was hoping upgrading to LOS 20 would improve things but not really in my case. I'm seeing many people are very happy with the stability and smoothness. So I started thinking, could it be because I have Magisk version 26.1? I remember reading that the latest version doesn't work but since it did work for me, I kind of dismissed the idea that magisk could be causing issues. Or is it because of some of the modules I have installed?

Modules I have:

- Advanced charging controller

- Fullscreen/immersive gestures

-MagiskHide Props Config

- Universal Safetynet Fix
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
The previous Magisk 26.2 wasn't working for me either (it didn't let me enter recovery, so I needed to flash "boot.img" and "recovery.img" in fastboot), but the latest Magisk Canary (26203) after updating worked without any problems.

The only modules that I have are essentially for MicroG enabling, and no lag, slowness anything. But as far as I know you can disable the modules or enter a recovery mode with anything already disabled to help you diagnose.

Did you had any success passing SafetyNet so far? (I don't need right now, and passing any attestation like this with MicroG it's it's own whole issue)

-----------

I'm happy to report that the latest release updated without any issues whatsoever using TWRP (I'm not recommending for everyone and that's isn't any guarantee that it would work for the foreseeable future) and flashing the custom kernel.

Thanks everyone!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xfoliate:
Well, I'm on 26.1 and I'm not really having any issues with it. Just trying to figure out if Magisk or modules in general could cause ROM to be laggy. I'm even having random reboots sometimes. I've had a few ever since I upgraded to LOS 20. I guess I'll have to do some deeper troubleshooting because I feel like this phone should run much smoother.

Yes, it's working great for me. I'm using those 2 modules and Magisk DenyList. I'm not sure if all these things are needed but it's working for me as is so I'm happy.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xfoliate:
It's still hit or miss on my end, don't feel any improvements.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dealerman13:
the logcat doesn't upload
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Probably it doesn't upload due to restrictions in size. So when I upload logcat I compress to the maximum compression level on 7zip and attach here on XDA.

And to make things easier for the devs who just wanna take a quick glance on the logcat (or any other logs) you can upload to those temporary text sites (you can choose up to 90 days).

So please try it again
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dealerman13:
Here is the logcat link, 7z isn't directly allowed, sorry for dragging thing out

https://oshi.at/xWvu
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Maybe I wasn't clear enough. Compressing any log it's required due size restrictions on the page per file type (I could be wrong as well).

So uploading to the temporary hosts it's useful, but if you don't put to expire in 90 days or any extended period, the devs couldn't see your log on time, so here on XDA it could last longer, but only if you compress it first. On those sites they usually don't accept compressed files.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dealerman13:
No I meant here on xda it says file extension not supported (or idk what it says), anyway I attached the 7z here to test if it uploads, regular zip isn't small enough, so rar?

I've missed a few updates before so I didn't notice I dirty flashed los 19.1 to 20. Are we supposed to clean flash or is it fine to dirty flash? So far, I've only noticed flickering bug I guess it's related to night light? Is there a chance to fix this because I noticed on other phone brand los has the same flickering bug.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Technically you can, and besides the instructions on the wiki regarding upgrades, here on this thread are at least 2 successful users who dirty flash and didn't have any issues, but other 1 who had FDE and didn't boot after upgrade because FDE don't work as clearly stated in the OP and the wiki.

The other issues could be related as you said and there are other users who have similar issues like yours. Since I don't use this function I can't really attest or reproduce on my device.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Sorry, that really was my mistake, because I didn't specify the file format. Glad you could solve.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] 0ldsoul:
So far I have yet to experience major bug. But at first I was having FCs because I didn't flash gapps. I just dirty flash over and over and followed the instructions. No more FCs.

Right now my only issue is screen flickering when night light is active and extra dim is turned on. Everything else that I was using so far works. But I think this flickering bug is present on all devices running los. Cmiiw. Samsung phone does this too and I thought at first it's device specific but it seems something has changed in the code and I doubt there will be a fix for LG since I heard it's kernel related issue. But it's okay, there's plenty of dimming apps in the market. Thanks devs for keeping our device up to date. So far it works flawlessly. We appreciate all your hard work. 🙂

Hello.

I have 2 V20s, H910 and H918. I have just rooted and put TWRP on them. Can I just flash this rom on them and can I still use TWRP? They are both on Nougat. Do I have to flash Lineage 15 and increment roms until I reach this rom?

Thanks for any replies.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
You should follow the wiki and use lineage recovery like it describes, we don't support any other use cases due to having a 4.4 kernel
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
I personally never had any success using TWRP to clean flash Lineage 20, it almost always have some quickness or bug, so I use the Lineage Recovery that it's released with the correspondent version > Flash Lineage 20.

Since Lineage Recovery:

A) Don't let me access my files trough USB cable like TWRP (Can be by design, but to me it's more a bug than a feature)

B) Don't have NANDroid backup

I use TWRP in the weekly upgrades until this day with 0 problems (and that's not endorsed/recommendable by anyone including myself, and it's not guarantee that it should work for future releases).

Be mindful, read the wiki, and enjoy Lineage 20
