Flashed the latest build 3 days ago.
Performance and Battery improved vs stock.
The camera quality is poor.
I also experience random freezes and reboots for an unknown reason.

--Updates--
Tried crDroid, PixelExperience, dotOS, and back to LineageOS.
Just flashed yesterday with NikGapps 10-13-2021, so far I have no problems with it.
Very smooth with great battery life. So far no hiccups, no random freezes and reboots, and no hangs.
Maybe the problem with my previous installation was because of the NikGapps, I'm not sure tho.
The only downside is its camera app which has very poor quality.
Tried ZGCam but still, Samsung's stock cam is way better than this.
Thanks for this wonderful rom.

Hey all,

Anyone know how to get ODIN to flash back to stock? When I try with the stock ROM files I get an instant success message but nothing changes on the phone. Must be something I'm missing.

Cheers

Latest release improved WiFi stability for me. Dropping maybe once a day now. No longer every couple of hours.

i'll give testing out the call echo issue another go, as far as im aware no further dev time has been expended in pursuit of rectifying the call echo

lineage-18.1-20211005-UNOFFICIAL-hero2lte.zip is the one im trying now.

can confirm that this still has the echo issue present and any call received through any medium will result in an extremely loud and unusable echo heard by the receiver.

great rom if you plan to use your phone as something that isn't a phone, but completely unusable if you wish to receive calls.

I tried both
lineage-18.1-20211005-UNOFFICIAL-hero2lte.zip with the stock kernel and then also flashing it all again and using moro kernel - both unfortunately result in the same bad outcomes

u already tried to use headset while calling?

the echo problem paired with the lack of the volte implementation will mean the end of this kind of roms in the near future. volte will be absolutely necessary when the 2g/3g technology is dismantled at the same time. there is probably nothing left (if u want to use a non-stock rom) but to buy a newer smartphone and not a samsung.

but anyway...thanks to the developers for their spending time to keep this old phone alive.

    Just a heads up Ivan. I installed the latest build ( wiping everything ) did not install any apps, and left it over night, the battery drain is very bad even though I had battery saver on, so went back to lineage-18.1-20210621, which is excellent, almost no battery drain in standby.

    Not sure what is doing this, maybe the updated kernal?

    I hope you are making steady progress on 12, me like many others really appreciate your hard work as you bring much joy to many of us keeping our beloved s7e alive and thriving :)

    it's like apologizing before punching someone...

    "Excuse me sir, i'm robbering you"
    it was just message to show developer how we care about his work, it wasn't meant to punch or disrespect anyone, So sorry if it sounded like that.

    So csmera is still an issue. I tried all possible cameras but still rendom crash. And i was planning to go back to this rom. :(
    20210621 build works perfectly, also the best battery stand by drain ( lose 1% overnight ), there are bugs in the latest build unfortunately.

    Hello there!
    I've been using this unofficial release of LineageOS for the past two months and I just wanted to give the devs and interested people some feedback!

    Let's start by listing the things I liked:
    • The OS is very stable. I never experienced any crash or any data loss from the system
    • Most of the functionalities work as intended
    • Huge boost of battery life
    • Android 11 on a system that used to never go past Android 8
    • Very snappy, the UI never stutters
    • Even though I never found a use for it, a built-in Terminal is very nice
    • No bloat
    Now for bugs I found/things I didn't like:
    • Camera app works around 20% of the time
    • Sometimes during a video call the camera will start to stutter/lag
    • WiFi will randomly stop detecting any available connections, needing to restart the system to fix the issue
    • Build uses public/test keys, so not that secure
    • Random broadcast alerts with random letters in them
    • Sometimes you can't change the wallpaper because the "change wallpaper app" crashes before you're able to select and/or set your new wallpaper
    That's about it! Thanks @Ivan_Meler for the amazing job and great effort! I'd love see this project improve!

    so what is it? does the camera actually work or not? anyone else care the chime in?

    also
    • WiFi will randomly stop detecting any available connections, needing to restart the system to fix the issue
    is a pretty MAJOR issue if true. again, anyone else?

    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

    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
