I tryed this 18.1 build with google apps.
Audio of phone calls is very poor (low volume) with normal calls, and using speakerphone for calls results as echoes in the call.
Additionally the fingerprint sensor don't work with my homebanking app i must use pin instead.
Also the VoLTE function is missing... so when i receive calls, the 4G connection is switched down.
Additionally the microsd card FAT32 format are incompatible and you must format into lineage filesystem instead.

So think about it before you do the flash this version on the phone, the build are unstable and very buggly.
I reverded to original stock android 8 firmware.

I did a clean install of this build.
Upon going to Settings > System > Advanced > Updater, it shows LineageOS 17.1 & Android 10.

Is this the case for anyone else, as well?


Nevermind, I never did flash this version. Dunce.

I am not having problems. The fingerprint issue was addressed in a previous post where they said: you need to reinstall the app. The MicroSD issue is because android uses EXT4 for its filesystem so i get why it formats it. The voLTE i am not sure about.

Also if you have read the first page of the thread you would have come across this line: Take a note that a lot of LineageOS features have not been completed yet this is not a device bug and please do not report those.

some bugs can be expected but it isn't a barely/not functioning build. Please keep that in mind when installing it. There is no software development team that makes the updates it is 1 person only which does it in his free time.

I also had bootloops with the last version (202101) even with cleaning properly fingerprints and lockdb file. I had to reinstall nik gapps just after flashing the rom to boot successfully to lineage. hope this can help ! (and I also have the anoying echo issue with classic phone calls, that's my only problem with this great rom !)

am I the only one to think that the "setting wheel" should not require to make the whole notification panel to appear before showing itself?

It should be on the first half like on other brands I had (Samsung or OnePlus) :)

how to make suggestion to lineageOS team? ^^

New builds are up, And one big change is that hwc is back and ui should be smoother than ever
here is a brief changelog that explains other chnges too
- Fixed HWC
- Drastically improved performance and battery life
- Added back flicker free dimming and fast charging switch (Now as hiidl interfaces)
- Switched to samsungs DT2W driver used on AOD on stock (Battery life improvements)
- Added custom LiveDisplay modes
- Disabled some excess logging
- Cleaned up codebase

HWC took quite a bit of work to get working again (Thanks google..) but s7 lives to see yet another year on up to date version of android

Big thanks to everyone who donated as they help keep this project alive I do this in my free time and said donations help cover build server cost and get me coffee which in return helps solve bugs haha

Tried on one phone and runs fine. Did clean install on my main phone and Nikgaps Android setup keeps quitting. Tried updating permissions but would not work and could not get google drive apps and settings back. Restored last 17.1 backup for now until I know that setup will work.

I installed latest niksgapps too and had no issues with setup at all

Uuuuh mega link is down and google drive link is locked due to many downloads. Shucks.
Yeah I've been trying for a while now, no luck so far. Really want to try this new build.
Try again now, i updated links 2 more times as i decided to make some final changes (disabled some excess logging which was slowing things down)

Downloaded the ROM again and tried clean install with Nikgaps latest and Nikgaps Android Setup. Android setup will not run, just get black screen so will try again with different gapps.

    New builds are up and as per requests of some people Signature spoofing support is added (In a way that doesnt make it a security threat as app has to be flashed to system,have proper priv-app xml permissions and user has to explictly grant permission for the given app) you can sue it with MinMicroG

    Other than that there are just some performane and satbility improvements, here is a brief changelog
    - Added signature spoofing support for MicroG
    - Cleaned up codebase
    - Misc performance and satbility improvements
    - Synced with LOSsource

    Big thanks to everyone who donated as their donations help cover the build server cost and keep the device alive more than 5 years after release with up to date OS and security patches

    Can't say it is buggy overall but agree that the random Wifi disconnects is a bit annoying...basically I lose Wifi like every 5 minutes~ish and has to reconnect (sometimes I have to enable and disable Wifi a few times to connect). Since I am using the phone as a Wifi-only device (i.e., no SIM card in there) it could get pretty annoying when the network connection gets cut off every 5 minutes....

    I also flashed the April build (originally dirty flashed but then it bootlooped so I factory-reset it), and it was the same thing as well. And this happened both before and after I rooted the OS.

    I have 2.4G and 5G sharing the same SSID and I downloaded a Wifi Analyzer it seems that the phone is always connecting to a specific 5G channel and doesn't switch to 2.4G (or any other 5G channel) at all. Also tried to turn on and turn off Wi-Fi scan throttling in Developer options and that didn't seem to help either.

    I am using AiMesh with Asus Merlin firmware if that makes any difference. My model is G930W8. Have a dozen other tablets/phones running in the house plus tonnes of smart devices and this is the only one that constantly disconnects, didn't happen when I was using stock firmware either.

    Not sure what else can be done. Anyone has any thoughts I'd appreciate your help!

    One nice thing though is battery is really amazing on this, I can get 2 days in one charge without any problems (although granted I run like probably 5 apps on the phone).
    I have an S7 Flat...with 18.1 ..7th April build...and ASUS Merlin with AI Mesh. I had issues with the S7 being the only phone that consistently dropped out. I changed on the router Adaptive QOS, QOS tab...Enable QOS to .off...and on Wireless, Professional Tab..Multi user MIMO to disable. My S7 now is pretty rock solid connecting to my home router...at 866 not 443 Mbps. I did read somewhere that the WIFI chip on the S7...was quite new when brought out and is not particularly stable with MuMIMO. My router is an AX88U...and this also worked on an AC66U B1...hope this fixes it for you...took me months to work this out!

    For the issues with reboots and corruption with SD cards formatted with the exFAT filesystem that have been discussed recently, those would be caused by an update to the sdfat driver, used for exFAT filesystems, in the kernel causing kernel panics: https://github.com/LineageOS/androi...mmit/ddba1674688968d672c5529068b8690ee5e79da7

    Over on another device, the Samsung Galaxy Tab A 10.1" (2016), which also uses a 3.18 kernel, I found that the updated version of the sdfat driver (2.4.5) caused kernel panics when writing heavily to an exFAT filesystem (on my SD card) using it. I could very easily cause a kernel panic by, for example, taking videos or downloading torrents to an exFAT filesystem mounted using sdfat. I'm thinking that similar issues are occurring here.

    Assuming that the issues are really caused by the update (I can't think of any other possibility), the only fixes/workarounds are to use a kernel with that update to sdfat reverted, or with whichever parts of the update causing the kernel panics reverted or a proper fix to the sdfat driver. We're still using an older version of sdfat, 2.3.0, over on the Tab A.

    No, you'll have to use TWRP to update.
    How to update soft for newer build version with TWRP without losing already installed apps - is it possible?

    -



    Take a note that a lot of LineageOS features have not been completed yet this is not a device bug and please do not report those
    in this rom thread as you will be reported to moderator also do not post bug reports for known issues or bug reports without proper
    a) Logcat
    b) proc/last_kmsg (or proc/kmsg)
    c) data/tombstones
    d) dmesg

    Also do not under any circumstances post bug reports if you are using substratum themes or unsupported magisk modules or you have performed any system modifications



    Install gapps right after installing the rom itself dont try to boot to system before that if you want to use gapps
    NikGapps and BiTgapps were both tested and working

    Downloads:
    If you are coming from pre January 2021 build remove fingerprints and delete /data/system/locksettings.db this is needed due to mobicore version change which helped fix fingerprint with 3rd party secure apps
    Google Drive
    Mega.nz

    I do this in my free time so bear that in mind when you notice I didn't fix known bug in next available build, Currently i work on this alone and i am not one of those kangers that just copy source and claim it as their own work,
    if you want to support the project feel free to buy me some coffee paypal.me/ivanmeler




    Feel free to join telegram group with early builds progress updates and some off topic stuff Join

    Due to requests from some users I added signature spoofing support to the rom which allows usage of MicroG
    you can simply install MinMicroG and grant it needed permissions for signature spoofing to make it work as intended
