I just swapped my battery and it flashed this rom and noticed that wireless charging does not work. When I put it over the charger the wireless charging animation blips for a second but nothing happens. The charger light is still on as if it's charging. Does anyone have the same issue? Or did I break my charging cord somehow? Thank you

Samsung Galaxy S7 Edge
Hello,
I flashed the latest update 1.5 days ago. I plugged my device to charge last night and then, this morning I have no button backlight. Also I did not modify any of the settings. I am waiting for your solutions.
Thanks in regards

Gcam For LOS 18.1
After install:
1- open the Gcam and DONT TAKE pictures
2- go to settings and wait 5-10 seconds
3- go back and take a picture
4- done

For a faster photo capture, follow the image below and select "1/20 sec." instead of "Slow shutter x2"

I seem to have similiar problems after the update.

Over the last night my phone went from 38% to 0 in standby. That has never happened before.

And just now the phone got very warm in my pocket. I hadn't used it and no apps where in RAM. Only a Whatsapp Message was reiceved on the phone...

ah what a shame, i thought this was the one but the echo on the receiver end basically makes this a deal breaker as a daily driver.

thank you for all your hard work on this, and i hope to return to it one day if the echo can be sorted.

Possible solution to the ECHO PROBLEM:

With the volume buttons:
- Press the volume down or up during the call and the echo will disappear.

At least this method works for me and I hope it works for everyone.

Note:
I use Simple Dialer to make calls, but the solution also works for WhatsApp calls.

You can download Simple Dialer from here:

Make sure to give permissions to the app as shown in the image below:

Hi all,

I have a SM Galaxy S7 edge with LOS 17.1 (even from Ivan) here.
Which is the easiest way to update to LOS 18.1 ... without loosing data(!)?

I would do like so:
- download LOS 18.1 (from here) and gapps to phone
- boot into TWRP (3.5.2_9-0 in my case)
- install LOS 18.1 and gapps (NikGapps-basic-arm64-11 in my case)
- wipe Cache/Dalvik
- reboot
Will this work?

I installed the ROM yesterday and so far it is perfect except the camera app makes selfies mirrored even I uncheck the option from camera options. Is there a solution for this bug?

    Here we go another security update here is a brief changelog
    - Merged October security update
    - Merged October Kernel upodates to 3.18.x
    - Added more advanced burn in protection
    - Misc performance and stability updates
    - Synced with LOS source

    Android 12 source has also been released so work on it will begin this week if everything goes to plan we will see s7 running yet another new android version this year
    Big thanks to everyone who supported this project by donations as their donations help cover the build server cost and get me a coffee, enjoy new build and stay safe

    About October security update and Android 12
    October update for android 11 should be out on monday which is also release date for android 12
    After figuring out 12 source android 11 and 10 roms will still be updated but most developement will move to 12.
    Keep in mind it might take few weeks before we have first usable build as I do this in my free time free of charge
    with help of donations of couse to cover a build server cost and get me coffee, Nonetheless s7 will live to see yet another android version after samsung abandoned it on oreo

    Big thanks to everyone who supported this project so far as its only thanks to them that its still alive and being regularly updated (mostly due to build server coost)
    Enjoy your weekend and stay safe

    Some progress updates on android 12, I got it compiled and while it does try to start kernel needs a lot of backports for cgroup to not kill processes and actually work, this will take some time but progress is steadily being made, Once again no etas yet as i do this in my free time

    This has been happening to me too. Since about April. I believe it started happening when WPA3 was added. I've not found a way to disable it. My wifi at least can be reset when I turn on and off airplane mode.

    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.
    yep already tried and tested and can confirm echo is present.

    I agree, volte will become absolutely necessary. Fortunately we have the likes of floyd rom and others with android 10, so it wont be the end of the world if we are just stuck on that forever.

    who knows though, maybe someone will work out how to fix the echo problems and it'll get back-dated. I'm sure someone with kernel experience will be able to fix it, if they feel the motivation to dev. floyd rom was a very poor performer with its original stock kernel but once morokernel was made compatible it fixed a ton of issues, as well as massively increased performance.

    The s7 edge is just far too much end of life now i think and most devs have moved away from doing proper support for the device, its now more like what low hanging fruit is available that can easily be back ported.

    I really miss the automation quick panel where you can control smart lights / other devices by pressing the power button. Thats an awesome feature of android 11 and will likely mean I have to upgrade in the future to get it.

    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
