On LOS 20, I have firefox and the Google Family Link app crashing sometimes.
Netflix makes an error (5.10) if I press +10s too often.

This did not happen on LOS 19.

Thank for the builds @Inkypen

Hi!

I just flashed TWRP odin-twrp-3.7.0_12-1.img then rebooted, installed lineage-20.0-20221116-UNOFFICIAL-gapps-odin.zip, flashed TWRP again using TWRP itself, and them installed Magisk-24.2.zip. No errors.

But when I boot into LOS there is no root, and there is no option to enable root in the developer settings.

For context, I had LOS19 lineage-19.1-20220910-UNOFFICIAL-gapps-odin.zip installed and rooted, including TWRP odin-twrp-3.6.2_12-1.img, all without issues.

Is anyone familiar with this kind of issue? perhaps I'm doing something out of order? What can I try/check, provide feedback/logs? (which kind? logcat? other/s?)

Thanks!


edit: Nevermind! I used Magisk app to patch odin-twrp-3.7.0_12-1.img and then flashed that in TWRP and it worked!(? i don't understand why it worked though, since I was installing TWRP after flashing LOS20 and then installing magisk.zip to patch the boot image, in that order).

I add to the list a bug probably on google services that affects the playstore. It is disconnected with an empty icon in the top right corner instead of the menu. A restart solves the problem.
This is probably the reason why Family Link is not working. It's totally random.
I tried to reinstall gapps without success

... and the round light on the fingerprint scanner that sometimes stays on and starts to annoy me.
If anyone knows how to disable it

Hi, just installed, automatically it went to B partition, TWRP is no longer decrypting (the new version you got in here), what should I do ? Install again on Partition A ? This should make TWRP work again so I can install Magisk ? Sorry to bother on this noob question, trying to search for a solution without any luck ! Regards !

Give this command via ADB: adb reboot sideload
It should boot directly in twrp and ask for decryption password.
Let me know

I have same problem with reddit, twitter or browser sometimes twitter says that sound is used by another app and video cant play, sometimes on browser video wont play or in reddit, have to close everything and open back or restart the phone.

I had this on all ROM I tried (LOS, EVO X and PE)

I'll try to catch some logs to help
I'm also experiencing this issue on LOS 20, latest build with gapps, running Firefox, it only happens if I have for example YouTube running in the background, Firefox will display an error at launch and no kind of media would play, only after closing it (Firefox) and opening it back again will the issue go away, it doesn't happen all the time, but it happens enough for it to be noticeable.

@Inkypen thanks for all your work man !

hey @Inkypen is there any other forum/place where you are communicating about your ROMs? just asking since there is little activity here and I see you're still doing the work on sourceforge and github - kudos to that! - I just would like to help testing / reporting issues

anyways - I've tried the newest January Lineage / PixelExperience ROMS - and they are both functionally flawless, but there are still 2 issues (in both ROMs) that still make me go back to Xiaomi.eu
  1. Battery drain - the phones dies overnight if I forget putting it on charger - and battery stats show blank for that time - on xiaomi.eu I can easily last 2-3 days on moderate usage
  2. Media/Camera handling - it is like others here report - camera sometimes is not able to connect, sometimes media can not play as if it was busy in another app
Other from that everything is miles and beyond better than anything on xiaomi.eu

Thank you again for your great work!

Consolidating some errors from this post and me as well

1. Battery: while mine doesn't die overnight, battery could be better
2. Sometimes ANX camera can't connect to the camera, but this only happens to ANX
3. Auto screen punch hole during selfies sometimes rotates 90* (leaving the hole on the left side of the screen)
4. Sometimes phone would reboot randomly, I had this for like 2 per week,

I can confirm issues 2) and 3)


Issue 3 often occurs during video calls.

I can't find system partition anymore in TWRP and mounting (showing system and system_ext) changes nothing, any idea?

    First of all, thanks for the update, but QR scanner remains broken on Firefox, just to try and help troubleshooting this, it worked fine on LOS 19.
    Try installing a camera app from the Play store such as Open Camera (also available on F-Droid in case you're Google free) and see if your QR scanner works. If it does then there is probably some overlay somewhere that needs to be set. Either way, I don't use Firefox so please send logs.

    Sorry, this might sound dumb but, how am I supposed to scan a QR code using Open Camera ?
    Install Open Camera/Google Camera or some other camera app. Open Firefox and read a QR code. See if QR code scanning now works in Firefox. If it does work, send a log. If it doesn't work, send a log. 👍

    Got some good news, got ANX working back to the same level as before (mostly everything works except for slow mo/hdr video recording)

    Just waiting for March security patch to release :)
    3
    March update is out and pushed to OTA system. Google changed the camera API yet again for QPR2 but I worked around it and ANX is back. I also updated the firmware to MIUI 14.0.3.0

    Check the updater app in System settings to get the update or download from sourceforge

    I also updated TWRP and fixed fastbootd, so that is now working in case you have need of it.

    I'm quite aware of all the issues with ANX. In the Pixel Experience thread I explained my reasoning for swapping out ANX with Google Camera in the latest PE build. It's becoming an uphill struggle to keep ANX functioning correctly, the current implementation is A13 source code hacked to be backwards compatible with the A12 camera libs and with each monthly security patch this approach is becoming more difficult due to changes to AOSP brought in by Google. I can't use the camera libs from MIUI 14 because they rely on certain symbols which don't exist in AOSP and no open source equivalent exists.

    I will try and get ANX working again but I can't promise anything. When Google finally decide to release the March security patch it's quite likely the next build will just have the Lineage Aperture camera app by default rather than ANX.

    Hi!

    Regarfing the ANX, is there any known workaround or alternative app that is able to use all 3 cameras?

    edit: some issues I've been experiencing since flashing this rom and even now after flashing this kernel, are ANX just frezzes when I select the .5x camera. And after taking a picture with the regular or tele lens, it closes, the picture is saved tough, but its annoying as hell.

    What can I do to help troubleshoot this issue? I'm just a power user though, not a programmer, I could provide logcat or something? Please let me know.

    Thanks!
    I've been using this GCam port https://www.celsoazevedo.com/files/android/google-camera/dev-bsg/f/dl129/ which works almost perfeclt - except the 0.5 lens does "squashed" photos - they look like they have been compressed horizontaly

    I have a test version of the kernel which will hopefully solve the random freezes when using multimedia apps.
    You need to reboot into bootloader mode to use this.

    Use this command to temporarily run the kernel (will be lost on reboot)
    fastboot boot boot.img
    Use these commands to permanently install the kernel (Custom recovery and/or root will need to be reinstalled)
    fastboot flash boot boot.img fastboot reboot

    Download it here:

    There also appears to be some issue with ANX crashing after taking a photo but other photo apps aren't affected. I'm investigating it at the moment, hopefully I figure it out quickly :)
    OK, media issues seem to be fixed, quick question, could you test if QR scanner works on Firefox ? Because for me it doesn't, it just shows a black screen.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 12 (S), which is designed to increase performance and reliability over stock Android for your device.

    Code:
    #include <std_disclaimer.h>
    
    /*
    * Your warranty is now void.
    *
    * We are not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at us for messing up your device, we will laugh at you.
    *
    */

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    Base source code is available in the LineageOS Github repo. And if you would like to contribute to the project, please visit our Gerrit Code Review.

    You tell me :)

    Installation:
    Reboot to recovery
    Copy LineageOS zip to internal storage
    Install LineageOS zip package
    Install [optional] a Google Apps package of your choice
    Format data (wiping is not sufficient, formatting requires you to type "yes")
    Reboot

    Important notes:
    GApps can only be flashed on clean installs.
    Formatting data (all user data is wiped, including internal storage) is a must if MIUI was previously installed and device was encrypted.

    New builds are up:
    • June security patch
    • Kernel upstreamed to 5.4.197 and latest lahaina CAF tag
    • LHDC Bluetooth codec added (untested as I don't have a BT device that supports this)
    • Some ANX tweaks (should start a little bit faster)
    Regarding the conversation about the visible camera hole at maximum brightness, that's a hardware limitation. You must have seen Xiaomi's promotional image of the pixel array above the front facing camera showing the smaller pixels allowing light to pass through to the image sensor. A smaller pixel will not be able to shine as brightly as a larger one hence the slightly darker view on max brightness. MIUI gets around this flaw by displaying a sun symbol over the camera hole at max brightness. On a couple of builds I tried limiting the max brightness by about 15% so this wasn't noticeable but I had a few people in sunny areas complain about the change, so I reverted back. If it bothers you just turn the brightness down a little bit.

    Are there any plans to fix the widevine level from l3 to l1? I know that the China/eu Rom habe l1,so it should not be impossible to fix
    I've had L1 support since before I even released any builds. Download any media codec info app from play store and check for yourself.

    New build is out, fixes seedvault among other things. Check changelog here: https://github.com/Inkypen79/OTA/commit/15f3c51b1ca99eaea2c026a47a6d0a02d3f5f583

    Turns out seedvault is a bug in Lineage, I used the main seedvault repo instead of the Lineage one and it's all working. This was fairly straight forward to fix but for future reference please, please, please provide build version and logs when giving a bug report.

    @subject4 Thanks for your suggestion. Nikgapps is actually what I would personally recommend if someone needed a gapps package, but unfortunately it can only be flashed on top of an installed ROM and is not suitable to integrate into a build from source.

    New test build is up. It has a new version of minimal gapps installed and it also passes safetynet from clean flash without the need of root or any additional patches or modules. OK Google detection is now working with the screen switched off. Biggest change is a much improved ANX camera experience. There are no more crashes when using certain camera modes, the only thing not working is slow motion. I'm considering making ANX the default camera for all future builds (gapps and non gapps) and I would appreciate any feedback about this change.

    Build is here: https://sourceforge.net/projects/xi...220426-UNOFFICIAL-gapps-anx-odin.zip/download

    Got another beta build for you to try with quite a few fixes/additions:

    • Safetynet issues are due to some changes Google did to their safetynet servers, this is now patched.
    • Fingerprint sensor not reacting unless you move your finger slightly is fixed
    • Lockscreen charging info added (was in last beta but I like the feature lol)
    • Github user KawaiiZapic was kind enough to have a look at the java code for the camera hole and has adjusted it so hopefully no more issues switching portrait/landscape modes
    • Updated Qualcomm SOC system blobs to newer versions (LA.QSSI.13.0.r1-09000-qssi.0)
    • Mark Akash ported Qualcomm's framework boost to AOSP, I've made the adjustments to enable this in Lineage (there is now a performance mode available in battery settings)
    Also thanks to @Kingzak34 who managed to get me a log of the random media freezes, this is not an isolated problem and some devs I know have the same issue on their Xiaomi lahaina devices. Hopefully a fix can be found soon.
