I have discovered I can shutdown and restart phone with this rom without unlocking by power button!
Why is it possible? Stock firmware doesn't let to do so.
It is the huge bug for security and availability of stolen or lost phone.
Is it LOS or rom "feature"?

Even if it wasn't possible to shutdown/reboot without unlocking, I think you can force reboot on any android phone by pressing (Power + VolDown) at least for 20-30 seconds, then do whatever you want with it, so it's no big deal to have that security in my opinion.

Instead this would be much more secure to put a pin code/password whenever you want to access the recovery. At least you can't do anything without flashing something, which requires a PC.

Thank you for explanation.

Hi,
I can also confirm, as reported by ukleinek and sammael1982, that the LED stops working after some time.

Usually 1-2 days after boot, it just stays off no matter whether it should be on due to charging, or blinking due to notification. A reboot recovers this.
For the notifications, the messages are displayed as well as notification sounds are played. Only the LED seems to be affected.

Hi,
Thanky you for the possibility to use my old devices with a current android.

I have an old Galaxy S7 (SM-G930F) and flashed the image from 2022-02-11 without gapps. I installed F-Droid and a texteditor, nothing more.
A free prepaidcard is used.

The device was not used since last full charge. So, why is there so much battery used in one day? Is that normal?

I 've used several Roms from Los and they had all the same error(s) : wifi was'nt stable and futhermore a terrible echo in calls. No difference in being called or making a call. Specialy the second mentioned is for me the reason I promised myself 'Never a Los-rom again. Although, I read here in this version is no echo. Is that correct?

No, unfortunately it has echo at least in Facebook Messenger (I've tested it personally). Anyways I don't think there is any better LOS at the moment for S7.

    August builds are up
    If you are wondering why those before 19.1, well google messed up and didnt push full august security update source for android 12.1 yet so those builds will be released next week.

    There are not too many changes as im still working on a huge rewrite of hals now that i have fully working s7 which is shaping up nicely but it takes time those new hals will work on both 18.1 and 19.1 and next lineageos version.

    Also android 13 is just around the corner (Probably next month) and from what i can see s7 is ready for it which will give us yet another android version to play with

    As always huge thanks to everyone who supported this project and helped cover the build server cost and got me coffee with donations.

    Enjoy n ew build and stay safe

    Donations help cover the build server cost and since I do this in my free time, and also cover the coffee for time spent debugging stuff



    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
