[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Moshimaru:
I ran into this problem as well. Android 11 seems to have this strange issue where the obb folder becomes completely invisible from the system. I ran into this issue on both LighthouseOS and SuperiorOS on my LG V20 H918.

Clean install from stock Nougat to A11 rom to get the fingerprint sensor working. Apparently hopping from stock Oreo to A11 borks the fingerprint sensor. Could not install any games with .obb files. The obb folder still exists when booting into TWRP and then mounting the internal storage to a PC to check it out, but when A11 boots up on the phone the obb folder disappears from all file explorers. Trying to create another obb folder with any file explorer won't work since it technically exists already. It'll just be named obb(1) automatically. I also tried sideloading the .apks and then copying the required .obb files from the PC to the obb folder on the phone while in TWRP but they still won't be detected by the games because the obb folder is invisible. The data folder IS visible but can't be accessed by file explorers.

I strongly suspect it's because of Android 11's dumb scoped storage restrictions that's become mandatory thanks to Google.

Unfortunately since I do game a lot on my phone and I also ran into the stupid A11 navigational bar bug as well I went back to the final Lineage 17.1 release for H918 which fixed all my gaming issues. Plus I was able to update the GPU drivers from another xda thread since the flashable zips don't seem to work in A11 yet anyways.

If you want to play big games with .obb files again, you might have to get back onto Lineage 17.1 to avoid the scoped storage nonsense.

The weird thing is the obb problem doesnt effect my other phone with lineage os 18.1 as the obb folder still can be access through file explorer thats why i thought my install was broken.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Hmm interesting, could you try kybs alternative kernel?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Gamma is actually based on the los15.1 source, los(18.1) is snappier cuz it's optimized better, gamma is based on 15.1 which is oreo. Interesting that you get better battery life on gamma, most people usually report that battery life is the same
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mmsp15:
Anyone know the benefits/differences between the Gapps packs. NikGapps/MindTheGapps/etc... which one would be recommended now since MindTheGapps hasn't been updated in a while now.

I installed NikGapps with this recent install (cause updating stuck me in a boot loop) so was wondering if there was any benefit to other packages or not.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Rom1995:
Which version did you use? I flashed the basic version arm64 and its working fine soo far.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mmsp15:
the Arm64 Basic... it seems ok for now also. I noticed OpenGapps also has 2 pack for 11 but unsure if their any good for los18 or not
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] aCIDsLAM:
Sure. Where do i find that? Dont find anything under "kybs".

Would be great to have an alternative, as i am having other problems with gamma kernel, which i dont have without...

Okay. Also with this kernel, i am not able to reproduce the problem. SDCard heavy writing works fine for me.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mmsp15:
My test was simply moving the LOS18 rom from internal to external and it happens every time time... Start transfer... Gets to about 70-80%... Shows crash screen... Reboot and sd card needs fixed... Instead of android fixing its way since it just thinks "oh let's just delete all content that fixes stuff" I stick SD card in pc and run chkdisk on it and fixes the Los file partial copy to not read as corrupt but not complete for me to delete it and try again with same result :p

Known that copying through twrp in recovery works just fine
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] MaverickNextDoor:
Hello everyone,

Please can anyone here install this app [Quick Video Recorder (by Kimcy929) on Play Store] and see if it can record in 4K (the app says it does but the developer says it depends on OEM implementation of camera framework). I'm running stock Nougat so I can't check myself, so I'd be grateful if someone on LOS 18.1 can help check. 4k recording on this app doesn't work on stock (it comes out as 1080p even when 4k is selected in the app).

Sorry this post is off topic for this thread.

Thanks alot in advance!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] aCIDsLAM:
You also having that with an custom kernel? It also may be SDCard timing related but with using gamma, fixes this issue for me, giving me other issues ;)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Jim SparrOw:
I have also faced this issue and went back to Lineage 17.1 still hoping someday it might get fixed. it's really disappointing!

Hey, for the cover sensor (magnetic) have you had any fortune looking into it? I'm still really in need of it!

I'm not really in a position to test nightlies, sorry. Is it still in testing or is it for sure going into mainline?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
It's merged into the repo, yes. Next build will have it.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] BloodyIron:
Yay! Thanks! So, should I consider the feature "tested and working/reliable"? Or what is its state? I'm not sure if it was hard for you to implement or not.

This really is an important feature to me, thanks! :D
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
Not hard to implement, just built our common solution for it - it should work fine.

If it doesn't though, probably means we'll have to use the proximity sensor which would suck.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Jim SparrOw:
Guys!! Finally I was able to download play store apps with obb and also install manually! just used x-plore. recently tried July 25, 2021 bulid and it worked!! Currently using it as a daily driver. I have flashed the MindTheGapps. Everything works!! one issue I am having is it drans a little more battery drain then LOS17. I am hoping to fix this problem using Ex Kernel Manager. I am trying out different settings to see what works best. if you guys have any suggestions please do let me know.

Like others, I am on latest 18.1 build, no root, no magestic, no alternative kernal just LOS kernal. LG v20 H910 and H918. 4 phones. Problem: LOS camera has no volume on video record. Using Open Camera on app store I can get volume because apk has setting choices on which mic to use. see attached. Is it possible to fix this issue so as to use LOS camera?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
logs/bugticket on gitlab like wiki details please.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] A.Whit:
I think hundreds of LOS users have logged this mic issue over several years and no fix is done. Here is a perfect example:

https://gitlab.com/LineageOS/issues/android/-/issues/2209

The problem is simple to verify on many different devices. No logs needed.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
Hate to be like this, but you clearly don't understand the issue if you're saying that.

Devices selecting the wrong microphone in the camera app are very much, device specific bugs, that are almost all different.

Some related to microphone input arrays, such as tri-mic setups that aren't being properly utillized, some are incorrect ACDB tables/ID, some are hardware issues where people have stuck paperclips in the microphone thinking it was the SIM tray (WAY more common than your think), some devices have issues with source built audio HALs due to framework side additions by the OEM - there are x^n more possibilities.

And all of them are different.

So, again, if you'd like help on this, I need logs of the _specific_ situation you've hit.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] A.Whit:
If you can say YES that you have a lg v20 H910 or a lg v20 h918 and the LOS camera on 18.1 records video with normal sound volume, then I owe you my gratification and appreciation and I will be very happy. thanks....
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ethansoars:
I bought a used H918 V20 and it came with bootloader unlocked and a stock-based rom installed. I bought it to replace my old H918 that suffered some water damage. It still works, though. On the new phone I wiped everything in TWRP and installed LOS 18.1. The fingerprint sensor doesn't work. Advice? Do I have to downgrade to Nougat? My old phone works fine with LOS 18.1, so is it possible to backup my old phone in TWRP and make a carbon copy on the new one to save the headache altogether?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
I can't! I'm hundreds of miles from my h918. It's at home and I won't be for some weeks... But still willing/able to help. Hence wanting logs of the issue so I can help solve it.

If you'd like to continue pointing at logs from a completely different situation that isn't going to help h918 whatsoever, go ahead - it just won't be productive.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] A.Whit:
I have tried twrp backup and restore for 18.1 but get errors on restore. That never happened on stock rom. I am still trying to understand why. maybe i need to use external sdcard, or as i have read others report same problem and its a twrp bug. i can confirm that there are files that twrp never backs up and also LOS is very picky and needs certain correct files to work ok.... example modem/baseband version.

you say your old phone was ok with 18.1 was the camera video record volume ok?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] A.Whit:

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ethansoars:
I managed to fix the issue by wiping completely, flashing an i95swervin nougat downgrade file, wiping completely again, then flashing LOS 18.1. I cannot vouch for this method's safety as I don't really know what it does, but it worked for me so I'll link the file for anyone wanting to try it. It's only for H918.

On my previous phone video audio only worked in certain camera apps like the default camera. I haven't tested on my new one yet.

On my LG v20 H910 with LOS 18.1 lineage-18.1-20210722-nightly-h910-signed.zip

(nothing else installed, no gapps, no mods, no root, etc...) the "LOS SNAP CAMERA" VIDEO record sound volume is almost 0%

SAME ISSUE ON Lg v20 H918 !!!!!!! I have that phone also.

After days of research and playing with mixer_paths_tasha.xml settings I gave up..... PROBLEM VERIFIED: its a LOS snap camera apk issue.

Then I installed ROM [android 11] UNOFFICIAL SuperiorOS-Xcalibur

1. Boot into twrp

2. Do a regular wipe (not format)

3. Flash Superior zip

4. Flash magisk (optional but recommended)

5. Wipe dalvik

6. Reboot

CAMERA VIEDO WORKS PERFECT !!!!

PERFECT SOUND !!!

To LOS maintainers: Fix the LOS SNAP CAMERA apk or quit screwing around with programming android ROMs. Simple as that. I am a MSEE engineering manager and if I cant do my job right I don't do it at all.

The LOS snap camera has been broken for a very long time (years) and many people have had to use GCAM or Open Camera and all these people including myself are sick that LOS maintainers can't fix a simple but very important apk in LOS (CAMERA video sound issue). This is well documented all over LOS wiki and github etc.....

"Hi @npjohnson

Open Camera (and BSG GCam 8.1) uses unprocessed-mic by default to get audio while recording video."

I am done with LOS until this is fixed. YOU ARE WASTING MY TIME
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
Yeah, considering h910/h918 are near identical, makes sense that they both suffer.

By your own statement, you're an engineer, and should be able to discern based on the info you gave me that it is _not_ an issue with the "Snap Camera apk", instead that we are using compressed audio path, and clearly it isn't processing right (likely a codec issue like I mentioned several posts ago). We could swap it to unprocessed mic input, but that will be garbled and awful - only using that as a last resort as opposed to actually fixing the compressed audio route.

As for the insults launched - k, stop using lineage then. I literally have not a care in the world whether you use it. I'm doing hard work for free, which, as an engineer, you should understand is often thankless, and your naggy/attacking comments only make me want to never touch the device again :)

I'll be looking at it sometime this week, but for everyone else on this thread who has been kind and supportive lol.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] BloodyIron:
Yeah I believe I tried the proximity sensor a bunch of months ago and it really was not reliable like the magnetic sensor. I'm likely to wipe and reflash my phone maybe this weekend, or next. I'll have to check if a release version has been put out yet, and I'm going to do that closer to when I can put the time aside as there's a lot of steps involved in my provisioning process (as you can imagine it's a critical tool for me).

I'm REALLY hoping it works though! Because the amount of times I double-tap the power button by mistake just to lock, and instead get the camera, is annoying. But the thing is I actually really want the double-tap function too because it gets me to the camera fastest in moments that time is of the essence, so it's a necessary evil, hehee. But if the magnetic sensor works, then I just flip closed, or open, to turn off/on the screen, etc, and that'd be rad!

I'm both excited for this, and also not looking forward to all the steps I need to take to do it, heehe. I really do appreciate your work though! Thanks dude! Even if it doesn't work, this is still appreciated. It's not like LG is going to help me ;P
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
Hopefully it works!

We don't do "release" versions, only weekly rolling builds.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
Maybe you should go back to stock? You do realize we do this for free and on our own time? If there are any issues we try to fix them ASAP but with your comments I doubt @npjohnson is going to want to support the device anymore. If there is any issue I would recommend reporting it in a less-hostile way and it might be a simple fix rather than insulting the primary dev for LOS on the device who may now not want to support the device anymore...
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
So, my girlfriend is at home, asked her to try it - and surprise surprise, Snap Camera's video recorded audio works just fine lol. Front and rear camera.

I did pick the patchset we merged on g5-common though afterwards, and merged it - it sounds to loud to me tbh, but enough people seem to like it better, lets go with it.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] MrKartupelis:
Format data partition, instead wiping it in TWRP. In my experiences, LG V20 can easily corrupt its data partition.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] BloodyIron:
Duly noted! That being said, I think I'm going to do it next weekend. I just spent like 16hrs wrestling with an upgrade to my main compie gaming rig, and I want to spend some time of today actually gaming, hehe. But I can at least take notes and plan my steps for redoing my phone.

H918, firmware version 10k. I successfully unlocked the bootloader but cannot flash recovery.

target reported max download size of 536870912 bytes
sending 'recovery' (26852 KB)...
OKAY [ 0.767s]
writing 'recovery'...

Googling suggested I should use an older version of platform-tools, tried it but that didn't change anything. Ideas?

Edit: With more research, I'm beginning to believe the official LOS guide is incomplete. According to many on the interwebs, LG removed flashing commands from the H918's fastboot entirely, meaning the only way to flash recovery is to use lafsploit. The thing is, lafsploit requires you to be on 10p or 10q, which are Oreo firmware versions, but this thread makes it very clear that a lot of things won't work correctly in LOS unless you're on Nougat firmware. Yet, if you are on Nougat firmware, you can't flash recovery...

Could someone from the Lineage team weigh in on this?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ethansoars:
I was having the exact same issue. Using gamma kernel now and I think that fixes it.

SUMMARY: I installed a bootable USB for my windows computer using FWUL_v3.2_x86_64_forgetful.iso

see: https://xdaforums.com/t/root-lafspl...-and-including-20h-now-n00b-friendly.3773443/

additional info: https://xdaforums.com/t/live-iso-fw...-installation-and-driver-issues-v3-2.3526755/

This is a LINUX OS for booting up on computer via USB boot and getting what you want done on your H918

Side Note: If you flash H915 firmware on an H918 -- you WILL brick it. So dont ever do that

FWUL_v3.2_x86_64_forgetful

>>>>>> flash usb using rufus program and >>>> select dd method

Boot FWUL

Login with username/password: android / linux

lglaf.zip

If you use Firefox in FWUL the file will be in the Downloads folder just like on Windows.

Open the runningnak3d prompt and type:

Code:

cd ~/Downloads

unzip lglaf.zip

./step1.sh

THATS IT !

system is the ROM

boot is the bootloader which must be unlocked. If you forced unlocked using dirtysanta then you have a "patched engineering bootloader"

aboot is your laf or downloader mode, you can keep default laf/aboot for LGUP usage or you can install twrp in laf partition thus have twrp in both revovery and laf...... your choice

QUESTION: Did ATT unlock your bootloader, or did you by using dirtysanta ?

also you must use LOS h910 version and a h910 modem. no exceptions

I have LineageOS 18.1 on a LG G5 (h850) and on a LG V20 (h910). On the G5 (LOS 18.1) that feature is activatable in Settings->System->Status Bar. It's not present on the V20 though. I already used it in LOS 14.1 on the G5.

At least it is in some builds of LOS.
