Can someone confirm that if you zoom in and zoom out very fast using Open Camera and its zooming slider, camera finally freezes permanently at some moment and app restart is needed or it doesn't freeze for you? My device is H990DS. I'm trying to figure out if I have faulty hardware camera or not.

Just tried that on 71% battery percent and I couldn't freeze the camera anyhow.
Then bcl is the issue
It enables itself on older batteries when reaching a certain threshold of charge, slowing the device down.

this is so you don’t face unexpected shutdowns.

if you want to disable it on boot, import this script to your kernel manager of choice, and allow it to execute on boot.

Nice, thanks. On Nougat base I had an issue with extended batteries for phone to shut down without "shutting down" message randomly, even some kernel crashes related to battery that were happening very rarely (even on an original battery). Likely kernel crashes were happening when I was changing original battery to the extended and vice versa . On original batteries I was getting shutdowns (with "shutting down" message) when battery was about 15% left. Also, after some update in June I stopped getting that infamous "modem crashed" kernel crash randomly, instead, I guess, I was getting reboots instead. However, I already got that modem crash on Oreo base. Also, I still didn't get random shut down (without a message) on Oreo base using extended battery. I guess I can try to flash Nougat modem to replace modem crash with reboot. I just remembered that that modem crash can be triggered by disabling some LTE band using Signal Guru is used by your carrier (In my case B1).

Modem crashes might be an issue on H990 models
Try mk2000 kernel

Thanks, but if I turn off Band 1 using Signal Guru, I get a crash, but it's different and in the blue background, not that in the black background, we will see how it'll behave in casual usage.

Did someone solve GPS issue on H990DS? It seems to be working fine in some places, but there are many places where other phones has fix instantly and I have to wait very long time or I don't get fix at all using GPS Locker. I tried Optimized GPS Magisk module and tried to replace gps.conf to the one of my country from some website but it didn't help.

    I thought I had encrypted my device (H990) but I noticed that it has stopped asking me for the password on reboots and while turning it on. It just goes straight to the lockscreen. My H910 still does it. Android settings says its encrypted. I also used the adb command to check for encryption state and it returned encrypted.

    Code:
    adb shell getprop ro.crypto.state
    You just need to set the secure boot password again.

    3.18 is EOL so there will be no more (security) updates within LOS anyway, right?

    If yes I'll just keep a copy of mk2000 around and reflash the kernel manually after every update.

    Thanks.
    Not for the kernel side of things, but that doesn't matter as much as the rom's security patch, which can still be updated if the rom is still supported, as was the case with CRDroid 7.21 for the V20 for example. That one has the August Security Patch in its latest 3.18 build.

    But CRDroid 7.21 is discontinued since we're focusing on bringing 4.4 alongside Android 12.1 (boots and is pretty stable in the latest closed betas, despite missing some features such as camera) and 13 (not really working yet) for the LGE 8996 trio.

    Please follow the install instructions in your device's Wiki page linked below exactly, and make sure your device's firmware matches the required firmware listed.
    If you don't follow these instructions, or use 3rd party add-ons (like Magisk) please don't expect support here.

    Known Bugs:
    • IMS (VoLTE/Wi-Fi Calling) doesn't work due to framework tie-ins used by the LG proprietary binaries.

    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

    https://forum.xda-developers.com/t/...96-11-unofficial-superioros-xcalibur.4248255/

    COMING FROM LINEAGE/RR:

    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
    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.

    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...

    Thread slightly cleaned!

    This is a development site and people contribute work as a fun hobby, NOT A JOB! They don't owe you anything but you owe the developers respect!
    If a ROM does not work for you, what did you do to contribute? Did you clean flash? More important, did you run a log of errors to help the developer? Just remember what you would expect in your profession. Or were you just too lazy to help and prefer to leech and complain?
    This world will only get better if we all learn to give instead of always taking! Please do not comment on rude posts, please report and a moderator will help.
    Thank you all for your cooperation.

    If someone could figure out how to get VoLTE working on LineageOS for this phone then it would solve a lot of problems. This is the fastest battery phone on the market that supports custom ROMs. There is no replacement for it.
