There's some bugs like mobile network speed is showing 0.00 and packet transfer showing 0mb constantly.
Also you cannot import contacts from sim card and call recording is not working for me.

Is there any way to record calls?

Hello. I noticed a very strange behavior of messages from applications, like the Internet is there, the sites open well, but if you change the network from mobile to wi-fi, messages begin to pour in, as if from some kind of buffer. And from different applications. ROM: 20220106.
Hi. I've noticed the same behavior as well. it's almost like a cache or that the network data side is going to sleep. I've noticed this on apps like Signal and Telegram. Seems to happen with wifi on or off but it seems noticeable after the device is locked (screen lock) and then you wake the device and then go to your app and a flood of messages update themselves or reconnect.
Any help Ivan would be appreciated
 
Anybody having the rom not booting up !
It get stuck on boot animation for me :( It was working just fine before. I have all my apps there n everything.
What should I do !
Assuming you were on LOS 19.0 beforehand, did you remember to flash Gapps when updating too?
Ivan previously posted about flashing both LOS & Gapps even when doing minor updates. (Assuming for Gapps you are using one without a update survival script like BitGapps)

True. I didn't flash Gapps after update. When the flashing was ongoing, it read in script that Gapps are being backed up then restored. So I figured no need to flash them after the update.
So should I Flash the rom again then flash Gapps?

I rolled back to the firmware, there seemed to be no such problems. lineage-19.0-20211220-UNOFFICIAL-hero2lte.zip

Thanks, I've just tried express lukes version of pixel experience on Android 12 and that doesn't seem to have this network cache (when disconnecting and then connecting to wifi again and then the messages flood in again) issue.
might be something in this particular firmware revision/latest changes. I'll wait until Ivan posts a response.

Hey I just did a fresh install of the most recent build and flashed bitgapps. I did this exact thing:
- On TWRP, I flashed Lineageos 19, then BitGapps12, then the Setup Wizard.
- When I booted, everything seemed fine, but nothing would download. All the apps during download are stuck on "Waiting for Wifi"
- I tried using Pixelify and Magisk Props Hide Config for Pixel 6 Pro, but neither of them did anything

Anyone else having this issue or have a fix?

First time I read about a Setup Wizard ! ???

Is it possible that you are not on the S7 Edge ?

Check in the play market - Settings - Connection settings - download applications - any network

Hello Ivan. After turning off the hardware keys of the phone, when I lock the screen and turn it back on, the hardware keys start working again. This problem exists in both LOS 19.0 and 18.1.
Thanks for the time you spent.

Yeah, here's the link to where I found it. It says you're supposed to use the config file, but I thought I would just flash it in TWRP. Here's the link to see the zip files.

I am on S7 Edge, trust me. I've used 18.1 as well and I'm finding it's more stable than 19 and smoother. Currently, I'm using NikGapps on Lineageos 19 and so far it's working except for assistant.

Update: So It is the setup wizard that is messing with the playstore. I'm not sure how, but it's blocking my wifi connection even though I'm connected to wifi.

Unclear for me where these patches are used for. The Bitgapps are functioning well and I don't use what I don't need. So I need the apps and not the patches (─‿‿─).

    - Improved battery usage logging for display
    - Added QR code reader to camera app (Long hold icon and launch it from context menu)
    - Misc performance and stability improvements
    - Merged May 2022. security update

    I also continued work and testing of new power hal ive been working on for past month or so, Hopefully ill release build with it in a few days (If time allows me as i do this in my free time as a hobby)
    Power hal seems to perform better and manage battery life and performance way better than curent one but i would like to test it further before releasing it

    As always huge thanks to everyone who supported this project and helped me cover the build server cost which is one of reason why this project is still alive keeping s7 up to date with software, New power hal will improve things even further so i cant wait to release next build with it

    18.1 and 17.1 builds will be out in a few days too

    Enjoy new build and stay safe

    My bank app is not working .. when it launch it give me ( app error) can you help me make it work?
    It's working with floyd rom and the PE 12
    But I want it to work with this rom because it lighter
    well you have to pass safetynet for it to work likely, My rom doesnt include any hacks so you will have to install magisk (24.1) and https://github.com/kdrag0n/safetynet-fix yourself you can use https://play.google.com/store/apps/details?id=rikka.safetynetchecker to check your safetynet status afterwards

    - Mobicore
    - SW codecs

    Not Working
    -


    Keep in mind that some LineageOS features have not been completed yet this is not a device bug and please do not report those
    in this rom thread, 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




    Install gapps right after installing the rom itself don't try to boot to system before that if you want to use gapps (Or wipe data before installing them)

    Since most gapps didnt update for 12L yet (SDK bumped from 31 to 32) i edited falmegapps and uploaded them here use them if you cant find gapps that work on 12L https://mega.nz/folder/FFoS1IIK#XunGRNTViQY7-OZ8oQr0sg
    Make sure gapps you decide to use support android 12L/12.1/Are targetting api level 32

    Make sure you are using latest official TWRP before installing rom older versions do not have proper android 12 support

    ROM OS Version: Android 12L
    ROM Kernel: Linux 3.18.x

    Version Information
    Status:
    Stable

    Well here are some progress update of whats happening behind the scenes.
    Ive given 4.4 kernel from 8895 another go and got even further in porting it to 8890 devices this time around.
    Mali drivers are ported so is decon (display and graphics stack is up)
    I also managed to port audio drivers, buttons and their backlight.
    UFS storage drivers were somewhat pain but i got them to work too
    and there is tons of small stuff like fp sensor,thermal driver and misc

    Tho im not sure it makes too much sense to do this as 4.4 kernel is eol too at least it has full bpf support which i got working on 8895 devices
    Other than that there is not too much going on right now, There are few selinux policies that will have to be dealt with and im still dealing with audio config
    tho i could only notice echo and not robotic voice some people noticed so that leads me to believe it could be related to weird modem missmatches

    I might release another quick build this month with few audio related improvements
    No etas as i do this in my free time, And as always thanks to everyone who supported this project so fat as thanks to them this project and device are still alive on latest android version even 6 years after its release (fun fact s7 series was announced on 21. feb. 2016.) so this is somewhat of a s7 birthday update on progress
    17
    Well here we go first build of the year, andquite a big one while at it
    Here is a brief changelogbut there are a lot more changes you will discover in this build

    - Merged January 2022 Security Update
    - Merged most of previously missing LineageOS features

    - Synced with LOS source

    Updates for Android 11 and 10 should be out next week

    About camera, As some of you might be aware camera tends to crash afterprolongued use, Im investigatinga fix for it but due to nature of issue itself it might take time
    to figure this out completely and what the best way to deal with it is.

    Andfinally huge thanks toeveryonewho supported this and other projects of mine so far as they help me cover the build server cost and get me a coffee with their donations, 2022 marks 5 years since release of s7 and im glad i can help in keeping them alive on latest android version with latest security updates

    Once again big thanks to everyone who supported this project and covered the build server cost and got me coffee , New builds of LineageOS 18.1 and 17.1 will be up in a few days and they will have camera fix backported

    enjoy new builds and stay safe
