I am not able to replicate the issue. See post 3 for gathering logs while you are experiencing this. I don't use WhatsApp. I don't think it's just a problem on the h990.

Just because it is official too does not mean it will solve all problems. It could be a WhatsApp issue.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
I doubt it. The was custom code LG did to have a single large display, but split it into a larger display and a tiny second screen. The way it was accomplished in 15.1 modified to much of the core of Lineage itself, so that code would never be merged into Lineage.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Lebatman:
Oh .. that's a little unfortunate, but nonetheless, thanks.

Any chance my other gripe - a lack of LG Cam would find resolution?

Are there no chances of someone leaking the camera drivers or reverse engineering them to be optimized enough for this phone?

I'd kinda happily sacrifice the second screen if I had this camera (Gcam doesn't cut it sometimes - too slow, with little manual control). By the time I think of moving to a new phone, which anyway won't have a second screen, I might as well give this one a new lease of life and live with a faster smoother OS with a notch instead.

This is not just on videos or on WhatsApp it cause slowdowns when it comes to pictures and videos

Otherwise the ROM was smoother than before

If following directions using ADB in 3rd post. Start the taking logs process, then open apps. Do .. then stop logs. I won't really investigate the GCAM issues, as that is very dependent on multiple factors.

Going official may not fix problems or have more devs on it. Going official means the device fits the requirements by Lineage: https://github.com/LineageOS/charter/blob/master/device-support-requirements.md Also, there is at least one developer that has committed time to help maintain the device. Right now only the v20/g5 is on the list, where the g6 is not yet.

[MENTION=2881807]x86cpu[/MENTION], is there a reason why the stock kernel has a refresh rate of 60hz while Omar's kernel has a refresh rate of 72hz?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] lybxlpsv:
no, try use a real refresh rate app (which is based on swap buffer time) and it will still be 60hz on gamma kernel.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Grin59:
No kernel for the V20 will enable anything above 60hz, it's physically impossible for the type of display panel it has to be raised above 60hz.

I didnt read

Just to be clear. Flash procedure for the h91810p stock rooted with twrp 3.3.1.1 and magisk 20.3 rom is.

Wipe dalvik cache+data and advanced wipe with yes.

Do I use to-x86cpu or to-unofficial?

So if yes flash to-x86cpu back(no reboot, nor reboot recovery),

then flash 15.1 (no reboot) to 16.0 (no reboot) to 17.1 reboot and wait? (how long can it take). feels like ive waited like 15-30mins just to go back to twrp.

If it works flash gapps nano, gamma kernel and magisk.

Is that the correct fresh install method?

Thank you/

Camera does play up a bit right after you flash the rom, but after a reboot and a few attempts to run the app it should start working, that normally works for me.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Landloord:
This is what worked for me.

1. Make sure you're on a nougat base

2. Format data in twrp

3. Flash to-x86cpu.zip and reboot recovery

4. Flash lineage 15.1 and wipe cache/dalvik then boot into system

Test camera and fingerprint sensor. If it works go back to twrp.

5. Dirty flash lineage 16, wipe cache/dalvik and reboot system. Test camera and fingerprint scanner again. If it works go back to twrp.

6. Dirty flash lineage 17.1, wipe cache/dalvik, reboot system and camera plus fingerprint should work.

7. You can now flash gapps and magisk in twrp.

This is what worked for me on h910, vs995 and us996

Nah no games even just watching YouTube heats up the cpu. but I've reflashed gamma v18 and the 2 recommended roms and the 1300ish CPU clock kicks in and runs below 50deg c. In kernel under settings it says kernel is gamma v18.

I use the phone a few hours later and it gets above mid 60deg c again and I noticed the clock speeds for the CPU arent throttled anymore. Is there a way to ensure the clock speed is always throttled? Worked we'll when it was throttled.

Thank you for replying,

I tried what you suggested. It boots fine in 15.1 but when i dirty flash to 16 it just kicks me back to twrp after trying to boot.

Sorry it is the v20 I've flashed, it says 3.18 on about screen and thought that was the version.

I've flashed the thermal config from Omar.

I was using the v20 a few mins ago and it throttled at 1036mhz on the CPU then went back up to 100% CPU when it needed to

Yes this was the same on Los 15.1.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] EnterTHEvoiD:
gamma kernel does a pretty good job cooling down this phone and if it still throttles and was throttling on 15.1 it probably means that the paste of your CPU isn't doing much anymore and needs changing..

Google Play download speeds & Youtube not loading

Basically, I followed the entire guidelines all the way through and noticed that my google play app downloads would be staggeringly slow. For the first second of download, they'd be normal and I'd get half the app if not all of it downloaded and installed. But larger apps, I tested it with Firefox Browser, would download for the first 50% but then plummet in speed, i.e. It would go from 20mb/s to 500kbps in 1 second. I kept wiping and reinstalling the rom with no avail and at first thought that maybe opengapps was the issue, but having tried different versions and eventually flamegapps, it had to be the rom. I checked forums on xda and other android sites with people just giving the same answers of clearing playstore cache and reinstalling it and what not. I've have tried almost all methods with the rom with even installing some magisk modules that could slow the speed to my phone to see if maybe it was too fast. Even when installing and trying to use youtube, it would never load. But, my internet speed to the phone was fine, I downloaded speedtest and was getting around 200mbps and downloaded some apks from the firefox browser the first time around which all downloaded quickly. It just the google apps not loading/not downloading apps and I just came to ask if anyone else was experiencing this or if I'm missing something completely obvious/a evident step I missed and whatnot. Anyway, any reply would be appreciated and I hope someone knows how to fix this because besides that, the os is amazing and I don't wanna not use it

Here's how I fixed the camera not working

These are the steps I did to fix the camera not working:

1) Format Data

2) Wipe everything at first

3) Install Lineage 15.1 (without to-x86cpu.zip)

4) Press Wipe dalvik/cache

5) Reboot

6) Setup and check if the camera works (if it doesn't stop here, this method probably won't help)

7) Shut down

8) Boot into twrp

9) Format data

10) Wipe cache and dalvik (Nothing else besides this)

11) Install Lineage 16 (again without to-x86cpu.zip)

12) Press Wipe dalvik/cache

13) Reboot

14) Setup and check if camera works again

15) Shut down

16) Boot into twrp

17) Format data

18) Wipe cache and dalvik

19) Install Lineage 17.1 (without to-x86cpu.zip)

***DONT REBOOT***

20) Press Wipe dalvik/cache

21) Install Gapps

22) Press Wipe dalvik/cache

23) Install Magisk

24) Press Wipe dalvik/cache

25) Reboot

(NOTE: this fixed the camera issue for me, so if it doesn't work for you keep trying different ways and look at the other pages in this forum. I used a modified version of what benhall847 did on page 38, check that one out if this doesn't work for you.

Magisk bootloops / fastboot

If you have magisk bootloop (stuck in fastboot).

Kind of as a note to self (I went through this a few months ago).

It can be because of an incompatible module (viper?). Not magisk itself.

Magisk modules are located in /data/adb/modules and can be deleted from TWRP. Like viper4android, which causes a fastboot bootloop.

There are instructions online for installing viper4android for android 10.

Only this one seems to work for me:

https://xdaforums.com/showpost.php?p=81138825&postcount=16

Credit to viv29 says:

I found another method which works with SELinux enforcing. Needs magisk installed.

1. Install the 2.7.1.0 viper apk from XDA Labs

2. Open the apk, grant it superuser access and press restart on the popup

3. Press power+volume up to go into recovery while it is restarting (dont let it restart, go into recovery instead)

4. Go to terminal in TWRP and navigate to /data/adb/modules/ViPER4AndroidFX by doing this:

cd /data/adb/modules/ViPER4AndroidFX

5. Now rename the post-fs-data.sh to something else like post-fs-data.sh.bak or delete it by doing this:

mv post-fs-data.sh post-fs-data.sh.bak

6. You're all done, restart into system now.

NOTE: Turning off master limiter and setting it back on doesnt work. It has to be on by default all the time (probably it enables at startup and cant be toggled)

If you encounter a bootloop delete ViPER4AndroidFX inside /data/adb/modules

rm -rf /data/adb/modules/ViPER4AndroidFX

It also makes me feel better, not being the only one being stuck on that.

It's such a nasty bug. Going from los16 to los17 (dirty, with viper4android), and you get fastboot bootloop. AND magisk alone has been known to cause fastboot bootloop. but it's not, it's just viper4android being incompatible with android 10. Unless you do that workaround.

dirty santa kernel

magisk 20.1 (last known working)

So I ran into a very odd bootloop that I was troubleshooting for the last two days - the ROM works as expected until the first reboot after installation. During setup and before my first reboot, everything is great with no issues. After a single reboot, the phone doesn't recognize the SIM, com.android.phone stops, and the phone reboots after about 60 seconds. When I remove the SIM and reboot, the phone doesn't reboot after 60 seconds. I finally narrowed it down to an issue related to the SIM and com.android.phone in some way, I think, though I am no developer and have no idea.

This is my only phone, and I moved back to Resurrection Remix (Android 9) so I can have a phone. I'm not 100% sure how to do a full log dump. I dumped as much of a log as I could which is are the logs generated from TWRP:
