[ROM][UNOFFICIAL][12]LineageOS 19.1 for Galaxy S20/S20+/S20 Ultra Exynos

Feb 13, 2022
So, I have bought a S205G and I would like to install LOS19.1. With my old S9 it was easy and I hope for the S20 it is the same.

However, the questions are due to the signature spoofing. I have made the changes of the services.jar on my own and it wasn't a big deal. you can find the instructions here:

In addition, there are other possibilities to make signature spoofing happen:

So, from my point of view, it isn't necessary to have a build-in signature spoofing in the rom builds.

Tried NanoDroid Patcher on this rom. Not working. Besides it's better to have microg embedded in the rom so not to mess things up. Thinking of moving to oneplus 9 pro. There is an official lemonadep microg lineageos rom since this rom seems to be abandoned.

I need to say you Thank You many,many,many times. You have done great job with this ROM and I think you give a lot of your time in this project <3 For me is it what it should be. Who need microg or gapps? I want this OS,because I want more privacy and google can be about everything,but not privacy.
And one good idea for those,who really miss the google maps,can be mapy.cz... Wish you all good night and say one more time thank you,Mr DeHuMaNiZeD. Peace

Samsung Galaxy S20
Ok, so for now, this rom is working beautifully.
Got Samsung Wear working, Google Pay, banking apps. 120hz is also working... so fine, so good.
The camera is far from perfect, but where it lacks in camera quality, it compensates in battery and customization.
Waiting (hopefully) for more updates :)

Have a nice day. When the Camera will be as it should be. Is not working. The sound is staggering, it should be at least 30% better. Handsfree free is not heard. I think that over the years, it could be better.

Any resource similar to the stock rom safe folder? Is the AOSP android multi-user mode possible to hide?
I need something like Xiaomi's second space or Samsung secure folder !

Samsung secure folder only works on a non rooted Samsung phone...

you might like to try Island from the play store if youre just trying to run an app in isolation

Have a nice day. Don't be angry that I'm asking, but does any of the developers on the camere and on sound boosting by at least 30%, especially hands free needs boosting. Thanks for the answers.

Among other things, I would rather like the TWRP, which is official for the samsung s20 and works very well with it, to work in the next issue of Lineage os. Thank you

    LineageOS is a free, community built, aftermarket firmware distribution of Android 12, which is designed to increase performance and reliability over stock Android for your device.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

    Reporting Bugs
    • DO NOT Report bugs if you're running a custom kernel or you installed Xposed
    • DO NOT Report bugs if you're using TWRP
    • Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)

    i am interested in MicroG too
    Yup. I installed twrp flashed microg. Microg and everything works perfectly. Very stable. But no signature spoofing. Keeping it as my daily driver.
