[MENTION=2881807]x86cpu[/MENTION]: Finaly i finished the test-marathon of the gps-issue. Even when i use another SIM-card (the one of my wife / not vodafone / T-Mobile Resale Carrier) the gps only works well, if i am in airplane mode. It is equal if i turn the mobile data on or not (outside the airplane mode)... The navigation app "Magic Earth" and "GPS-Status and Toolbox" App (same one as you use) loose the signal after some seconds and every couple of minutes.

With a fresh/blanc flashed lineage it is the same.

With a stock based rom (like Alpha / Weta) there isn´t that issue.

I am getting confused, because you use an us996 too as well as the app "GPS Status and Toolbox" and lineage and so i am finally stumped.

Because i am using completely offline-maps and no traffic service e.g. i am ok with going in airplane mode, before starting the navigation.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Are you able to provide 2 logcats? One with a "working" GPS, and another with "failed" or loss after a bit. Preferably a logcat -b all -d (-b all shows all buffers, including radio and kernel). Clearly mark them so I know which one I'm looking at. ;)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] CM-Tester:
Sure i would like to do that. Because creating a logcat is new for me, i have to read a bit about that. Is it ok for you, that i would like to create the logcats with an app (e.g. Catlog)?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
You could, but catlog won't be adequate. I need all the buffers, that just doesn't catch them all. No updates since 2015 either. Not sure which one night be able to catch "all". I usually use it through abd shell.

---------- Post added at 02:55 AM ---------- Previous post was at 02:50 AM ----------

This one does it: https://play.google.com/store/apps/details?id=com.dp.logcatapp

Just make sure you go into settings and click to enable all the buffers.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] CM-Tester:
OK, in the next days i drive a bit with my bike, then i will create the two logcats.

Thanks for the advised app.

On top of [MENTION=2881807]x86cpu[/MENTION] experiment for data collection. Have you tried using the gps.conf file from WETA in LineageOS?

UPDATE: You can try this out by flashing : flashable-lge-v20-lineage-hotfixes+gps.zip

UPDATE#2: If you see the following : https://github.com/LineageOS/android_device_lge_msm8996-common/blob/cm-14.1/gps/etc/gps.conf

You would see that it has a big bunch of differences.

I too myself used to get sporadic GPS signal lock messed up from time to time. And it is less noticeable when driving in a car than when walking or biking... so far using the updated gps.conf from WETA and I don't see a problem and the GPS lock in my case becomes rock-solid.. we might want to see that nothing breaks out by updating the gps.conf and that it indeed fixes problems reported by other people and then we can decide if this needs to be changed upstream :)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] CM-Tester:
Thanks ;) ... well again a lot to test :D

Tomorrow i ride my bike a bit, so i will create 2 logcat-log´s at first for [MENTION=2881807]x86cpu[/MENTION] and after that i will test with the alpha gps.conf and your weta gps.conf. I think i will be ready with all latest at the and of this week and then i give feedback here :cowboy:
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] emdroidle:
Qualcomm has shipped drivers for the MSM8996 ("Snapdragon 820") for the 4.4 kernel. LGE could update their V20 code to run on the 4.4 kernel without too much difficulty. Unfortunately there is speculation this is unlikely, but it is possible. Failing that, if developers want to stick with this device long enough, we might be able to do the update ourselves (might be worthwhile given the combination of things available on this device).
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] CM-Tester:
Today i did some trips with my bike and the results are interesting.

[MENTION=2881807]x86cpu[/MENTION] I recorded 4 logs with the app you had advise above. Only the "logcat.zip" is secured with a password. I send it in an pm to you right now, directly after this post.

So the 4 logs are clearly named and described here:

1. With original LOS gps.conf in "normal" mode with activated mobile data (recorded about 5 minutes)

Result: Lost gps-signal after about 5 minutes (after it i stopped recording with logcat)

2. With original LOS gps.conf in "airplane mode" (recorded about 10 minutes)

Result: Worked perfect

3. With original ALPHA-ROM 1.5.2 gps.conf in "normal" mode with activated mobile data (recorded about 45 minutes)

Result: Worked perfect

4. With original ALPHA-ROM 1.5.2 gps.conf in "normal" mode with activated mobile data AND UPDATED AGPS-DATA IN THE APP "GPS STATUS AND TOOLBOX" (recorded about 45 minutes)

Result: Worked perfect

So after all i can say, the LOS gps.conf is buggy, when i am not in airplane mode, while the Alpha-Rom 1.5.2 gps.conf works good in both modes.

---

For everyone, who would like to test the aplha-rom 1.5.2 gps.conf too:

I had uploaded it here to my post. It is in the zip "gps.conf_ALPHA-1.52" (without a password)

You have to copy (overwrite) the "gps.conf" from the zip to the root directory "\system\etc"

BUT SAVE YOUR ORIGINAL gps.conf BEFORE !!!

Hope, that helps someone too...

I am glad it worked man... ;), I knew that conf had something wrong :)

Hey everyone, I finally made the jump from a stock rom to AOSP. I'm on an LS997 (Sprint) and I think I've got everything configured correctly but every time I reboot the phone I get a SprintDM message saying it's "Configuring Cell Network" and can't seem to find anything on it. I did notice my MIN is unknown and PRL is blank under the IMEI info. Also it seems like if I'm connected to WiFi when I reboot I lose the ability to text. Has anyone run into this issue before?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
You are having issues because you needed to clean flash the (I think) 5/8/17 ls997 rom first then update to the most recent. That should solve those issues. On the Sprint dm, titanium backup pro and freeze the app. That's what worked for me.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Wabem:
Any clue where to pick up this build? I checked the archive but it looks like it's borked for whatever reason (only the first one is showing up). Also, I can't seem to get Magisk working, is it working for you? It might be because I flashed the add SU addon and then the remove SU addon before I flashed Magisk. Thank you for you help!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
I have it on my machine but I'm not at home until late (11pm CT).

https://www.lineageoslog.com/14.1/ls997

There are a few builds here but you're right; I don't see 20170508. I'm sure I have it on my home machine. I can upload it to mega late tonight or tomorrow. magisk works great. I'm on all the latest releases. You might need to start all over because of what you said about the SU add-on but I couldn't say for sure. One more thing I just thought about. I used the dirty Santa sprint rom that me2151 provided to update my profile/prl FIRST. then I clean flashed the 20170508 then dirty flashed the latest (in my case 20171108) and have been updating each weekly. For magisk, don't flash it with the rom. Just flash the rom and GApps and reboot. Then install the magisk app and install the framework from the app itself. It will do everything from the app.

Edit: it was the 20170526 build and I'm uploading it now.

Did the log´s help you, or should i provide some more logs?

If so, which combination of settings do you need ?

PS.

The 4 log´s, i already did record, are incl. all buffers.

I need help like really bad, just flashed from RR N to this and with RR N I was getting stuttering on any video app Hulu Netflix youtube the audio and video stutters every few seconds it's driving me insane and even a clean flash to this rom it's still not working, my last thought is go back to weta (which I really don't want to do) and if that doesn't work to trade the phone in, I spend a decent amount of time on said video apps if anybody could help me out it would be appreciated

Also my data connection is lte thats usually fine on said apps and my WiFi is hitting about 150mbps down

I just received my V20 and I have one question about the second screen support. Are we in a galaxy S5 finger print scanner level or is it very locked out? Just curious
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] CM-Tester:
Since a year, there is a bounty thread here on xda for the second screen:

https://xdaforums.com/v20/how-to/progress-screen-api-aosp-t3549121

It seems, second screen will not really come for the v20 outside from a stock rom.

But i think, it isn't really important. I use the v20 since more than a half year with LOS and without the second screen and it runs good. For me, it is much more important, that we have a powerfull phone with a changeable battery.

PS.

I don't really need the second screen and because the part is black, i do not notice it, but a thing i really miss, is a notification led. In the far future, my next phone must have a notification led again. It is much better than a secend screen ;)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
Try LIGHT MANAGER from the play store. It's a LED notifier, but play around with it and you can get a half way decent substitute for a LED
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] TheLoonyRebel:
So I'm assuming those of us who are on 10S on our H918 also no longer can use Lineage due to the bootloader?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] CM-Tester:
You know the v20 do not have an notification led!?

Does this app imitate an led on the screen?

Edit:

NoLED seems to be outdated since 2013, so it isn't a choice.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
First time ever had problems with cellular signal. The ls997 03.02.2018 update was the last thing I changed before it started acting up. It gets a normal signal - calls and text work. Then after a few minutes it is gone. Rebooting brings it back temporarily. I tried fixing it by dirty flashing the previous build but the damage was already done. Now I'm on the dirty Santa LS997 build and it's fine. I updated prl and profile and running it today to make sure it's not hardware. I'll back up the EFS again and reflash LOS tomorrow to see if it persists. I'll report back then.

Update: had time to be sure it wasn't a hardware issue. Never lost cellular on dirty Santa ls997 rom; then tested LOS 2.15.18 update for a couple of hours and it was fine. Now running LOS 2.22.18 update. It seems fine. No cellular problem. I might try the 3.2.18 update tomorrow to see if I happens again.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
Update: I have completely restored my phone to the same version ls997 Los 3.02.18 build and it is not duplicating the problem. It's behaving normal. Very stable so far. Now I have no explanation for why I lost cellular a few days ago.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
Well I'm very sorry for the contradicting posts but after further testing on LS997 3.2.18 BUILD , it's too problematic to run as a daily driver. The restore never lost cellular as it did the first time around but calls are not up to the quality of all the previous builds since Nov. I hear them fine but I'm breaking up in every call. I just tried to restore EFS but that didn't help. I'm going to restore my last backup from 2.22.18 which was basically flawless. I really hope this isn't the end of the line for LOS LS997. I'll try the next release and see. Fingers crossed.

Update: 3.9.18 has the same problem

---------- Post added at 09:21 AM ---------- Previous post was at 09:10 AM ----------

OK; I'm having an issue I'm hoping someone might know a solution to: I installed this on my unlocked US996 V20, and I chose to use the shared storage option so that my internal & external storage are seen as one, but now my PC is saying that my available storage when the phone is connected to it is only 50.7 GB of Internal Shared Storage, and there's ) bytes free! The phone reports that I'm using 185 GB of 364 GB total (I have a 200 GB SandDisk MicroSDXC card in my phone), but it shows 183 GB used of 183 GB total Internal Shared Storage, and only 2.40 GB of 180 GB on SanDisk SD Card.

What's going on here? Anyone know how to fix this, or make that unused space available to transfer files from my PC to my phone? I'm not able to currently transfer any more music or photos, because the PC reports my phone storage as full. I see no option anywhere in "Storage" (in "Settings", on the phone), to undo this shared storage option.

Thanks, in advance, for any help or suggestions anyone might be able to provide me.

While we're touching on the subject of the ARB and how many users can't install due to issues relating from it, I've been thinking about ways we may be able to accommodate users who are on later firmware with the ARB fuse tripped. What would it entail to modify Lineage to work on a device with a tripped ARB fuse? Is it basically a value that says "Hey we're on ARB version X" which could be changed and compiled to run on that version or is it deeper? Also When Lineage goes to v15 I assume it will be based on Oreo. For those who have ARB 1, would they then be able to install v15? I know there was talk about possibly getting 15 to run on the V20. Not pushing, more musing. I'm trying to understand what's happening under the hood so to speak.

ya that swipe issue is the same in stock if you turn off the 2nd screen. thats the only reason i kept it enabled on stock.. it just takes a bit of getting use to

what carrier is that... was planning on expanding this weekend

turn of ambient display... (i should just disable it for now honestly) still working on a fix

and we arent using overscan.. trust me i spent hours with that. the code is screwed up with it and messes with scaling. what we are doing is offsetting the display so it starts writing 160 pixels down from the top and then set the display res to 1440x2560 via a build prop override (which sadly still causes tiny glitch when rotating or locking phone but i'll figure that out) i'm sure that bug and the one with overscan are both the same bug...

honestly you have a better chance the spr or vzw owners as its gsm.... there are only 5 files you need to replace in this rom with ones from att to at least boot

/system/etc/firmware/a530_zap.b00

/system/etc/firmware/a530_zap.b01

/system/etc/firmware/a530_zap.b02

/system/etc/firmware/a530_zap.mdt

/system/etc/firmware/a530_zap.elf

edit the updater-script in the h918 zip you downloaded by removing the assert line...

flash...

DONT REBOOT

go to mount

mount system

adb push the files i mentioned

profit

I dont have this issue. have you installed any mods

i'm not going to but it should be easy for anyone to pick it up... the device trees and kernel are made they just need to fork those and build for those roms. should be minimal if no effort. all other projects are forks of CM. so if the device supports CM it supports the other ones just matter of building. i dont really have the hdd space to sync multiple rom sources they are like 60 gbs and then like 130 after building

why dont you try what i said, you quoted the post... Honestly the devices are pretty similar besides cdma and gsm. the h918 build should work on any variant if you just replace those 5 fw files with the ones from your variant.

Awesome work! One issue i've noticed, and really not sure how to address it after digging around the source a bit, is the backlight from the second screen casting a shadow. I think in disabling / preventing overflow into the second screen, the backlight in the middle of the screen drops out.

Other than some issues with .dataservice FC'ing, (i'm assuming a gapps issue). This ROM is super quick!

just use muppets... theres nothing really useful on my repo just test stuff... but if you do feel the need to use the cm-14.1 branch of any repo u use of mine

thats not what i'm saying... READ.... i said to copy 5 YES 5 single files from the stock rom to your phone AFTER Flashing my rom and still in recovery... seriously i'm not explaining again...

whats going on is the backlight for the 2nd screen is set a 0. go into stock and turn off the 2nd screen it will look kinda the same... i want to link the property for backlight brightness for main backlight to 2nd one just havent got around to it yet. you can manually increase it by echoing numbers to a sysfs path and it goes away... i forget the path though

yeah i noticed the .dataservices fc... dont really know whats going on with that yet... minor issue it seems though...
