LineageOS 20.0 (Android 13) [Signature Spoofing][OTA updates] for S7 Exynos

[ScanX]

Sorry for huge delay this time around but google was late with source release, they also made huge overhaul which took time and effort to merge and to top it all off i had major issues with build server i had to restore, But builds are finally here.

You have nothing to apologize for ivan.
Many thanks for your tireless efforts!

ivan tell me, why isnt your rom based on los 20 fully encrypted?! For exemple one plus 5 is encrypted by default in official build and its same old device. Where is the problem?! We need fully encrypted device.

Dude be happy that it runs at all on our device. If you read the OP you will see that its WIP

 

[Ivan_Meler]

New builds are up with fixed double tap to wake, sorry for inconvenience

@Ivan_Meler

THANK YOU for all your efforts. Have now running successfully two Samsung Galaxy S7 with your LOS 20 rom, and I am happy with that.

I would like to donate your work, but I dont have Paypal. Please give me a private message and tell me, how I can transmit you some donation.

Thanks for this great rom.

With the version from Feb 8 I had some issues. I used it without a SIM card and when moving around (used it for navigation) sometimes I could not unlock it anymore and the clock was looking different. I had to force a reboot when this happened.
Later I set the device to flight mode and this did not happen anymore.

The latest verion has some issues with wrong icons:
Unlock, swipe down from top. Now the symbol for wifi and flight mode is black but the symbol for battery stays white.
In dark mode the colors stay the same, wifi and flight mode almost invisible.
Unlock, swipe down from top twice.
The button for settings is white and almost invisible.

Yesterday i tried, after reinstall unable to delete files with twrp recovery i had to upload stock rom in odin. Nothing worked.

Try to tell the forum your concrete problems, maybe we can help.

On my Samsung Galaxy Tab A 10.1 (2016) tablet I also had the problem, that mounting, wipe (formatting) /data was not possible in TWRP.

But there is a solution how to handle that on youtube:

Watch this and read the instructions in the video, if this is your problem!

Beside this, if TWRP is on your device, than all other should work also.

I run two Samsung Galaxy S7 smartphones with LOS 20, and the u.m. Samsung Tab A 10.1 (2016) tablet with LOS 19.1, all devices work properly with LOS.

Please be patient, and read all instructions carefully. In the regular just not following the instructions point by point is the problem.

You will make that!

Came back to LOS20 to do some testing...

The system is running very well with good multitasking and excellent performance

I encountered some occasional lag when opening the camera in different apps. I also faced a bug once where I had music playing and the phone crashed with a loud error sound.


But
My main complaint here is battery life
It's draining a lot with screen on usage
I checked the Frequencies that the CPU are using and I've seen that the Big Cluster is having some sort of touchboost at 1248mhz and Little Cluster is at 754mhz

Considering the Frequency Table in stock all have lower minimums I tried to modify it by using simple methods but they avoid being kept at place.

The minimum frequency of each Cluster is higher than usual as well...

 

[netra3441]

man last build is full of bugs. you shouldnt use official rom name Lineage. lineage is synonym for security and stability. yours should be called stupid ivan rom. latest official version was lineage-14.1-20190224-nightly-herolte-signed. if you dont have time rather play football. try last official b. it was thousand percent better and it was android 7. here is link https://drive.google.com/file/d/1RFYM_OV-5JIMYWS4FHpkoVbxvb5yIQhx/view
try it how stable and secure it was.

Hello mate,

if you have complaints, three things apply here:

1. Please write in clean English and if you can't, use a translator app.

2. Moderate your tone, insults will not get you anywhere.

3. Write in detail what problems you have or where you see points of criticism.

Without observing these forum rules, which certainly make good sense, your input is completely worthless.

Well... the battery life seems really to be a little weak... I own my Samsung Galaxy S7 since 2016 and do not remember yet, how it was with stock rom.

Second, I have in each room of my apartment charging units, and when I was outside f.e. with a car (what the last years did not happened) I always had charging cable in the car too.

So, I charge my S7 two times a day. Isn't that normal?

 

[netra3441]

both 19 and 20 LOS unofficial drain battery. sometimes the phone is very hot.

it is clearly written. it has nothing to do with Lineage. it's only beta and not safe to use. there is no encryption. there is no SElinux, it's just a stupid port. there is only one official Lineage.

There are a few things you don't seem to know or haven't understood yet:

1.
Every LOS supervisor/maintainer does this on a voluntary basis and free of charge, and has a lot of work to do with it. If you're now swearing at @Ivan_Meler, that's simply not okay.

2.
Can you do it better than Ivan? If so, then prove it - but don't scold him, ok?

3.
Unfortunately, like other manufacturers, Samsung has packed different technology into its smartphones. That's why there are S7s that get warm, others, like mine, don't. Same with other issues.

4.
We can all be happy and grateful that LineageOS and its maintainers exist, and that we can use up-to-date Android on our legacy devices! We all have to be equally grateful to the people here on XDA for making this forum available.

In short:
The way you are appearing here is not correct.

 

[netra3441]

I think one of the reasons I use custom software is that it's better than stock in many ways.
but if it's worse I won't use it. i tried ten versions and they all had lots of bugs. and I think that's important if I use the device on a daily basis. I use banking apps and social apps and this person is not credible to me, when he releases software with bugs. there is no room for mistakes here. we are not hostages. it's not about what version of android I have. it's about security and reliability. and yes samsung does it their way, but that is also the reason why S7 is not supported LOS officially. I will give an example. try graphene os. there is no application, but everything can be installed and everything works. why do I have a pre-installed browser here, which has permissions and cannot be removed?!

I'm sorry but you don't understand:

Nobody takes you hostage. You either use LOS and accept that this is voluntary and unpaid volunteer work where not everything is perfect, or you don't.

So it's better to just buy a brand new smartphone with the latest StockROM and that's it.

Or compile LOS for your old device yourself and do it better than Ivan.

If you can't, keep quiet instead of incompetently accusing the man.

I use my S7, which I have owned since 2016, also daily since LOS 18 (Android 11) and also with social media and it always does what it is supposed to. It runs also fine with LOS 20. Better than with LOS 19.1...

I don't use banking apps because online banking with mobile devices, which are insecure per se, is just nonsense. Also I never do online ordering with online payment, because this is same nonsense.

Again, constructive criticism is always welcome here. But not rabble and bashing.

If you have something to say, present it in a concrete and orderly manner, provide references to your findings. But if you only bring generalities, you can do that too, because not all of us are programmers, but do it politely and friendly, and never forget that you didn't pay a cent for LOS, so you have zero claims.

I really don't understand what some people think...

You are also comparing apples to pears:

GrapheneOS works exclusively on Google Pixel devices.

If you like this thing that much, then stay there and don't start working with an S7, which is a hot potato indeed, because of course manufacturers like Samsung are always trying to make it difficult for the people at LOS.

Realize that manufacturers see LOS as an enemy because LOS allows customers to stay with their old device longer or even forever. Manufacturers like Samsung just want to cash in, an alternative operating system just gets in the way, so measures are taken.

As far as I know, this is different with Google Pixel smartphones and GrapheneOS: Google technicians work there... so a completely different starting point than if you have to completely adapt an OS to a smartphone whose hardware manufacturer also builds in obstacles. ..

Come down from your sense of entitlement.

If you like GrapheneOS better, buy a good used Googe Pixel and live and work with it. Absolutely okay.

But don't scold @Ivan_Meler here without any substance or background knowledge.

Here are many who use Ivan ROMs and appreciate the quality of them. Just ignore the troll!

You charge your phone twice?
Interesting...

I've been stuck on Pie One UI up until now so I'm just comparing those while being aware that we're not using an older version of Android.

I just wanted to be able to use lower CPU minimums to ensure music playback battery life can be reliable and the Screen on time is not drained away by simply messing with the UI...

But regardless, it is being an amazing experience to use A13 this fast in our devices!

Yes, when I use it often, I charge minimum one time per day, in the regular twice. But this is, since I have it, since 2016.

And yes, the S7 has a very good hardware, and @Ivan_Meler does a good job though...

 

[netra3441]

LOS https://lineageos.org/ is I always work perfectly without errors. but people outside this project using the same "brand" are not doing a good job. you're right, it's different hardware, yes the pixel has Titan M chip. but anyone using a custom rom should have the option to to encrypt, lock the bootloader or set permissions for single apps, without these basic things it is not usable. OK let him make his own software but don't call it Lineage. the official build works perfectly on samsung s10 on S7 it's a nightmare.

Man, you still dont understand!

Each LOS rom is done by a maintainer. @Ivan_Meler is just one of them.

When the maintainer of the LOS for the Samsung Galaxy S10 had built in those functions, you prefer, than this is a special thing of that special maintainer.

@Ivan_Meler had not included these features, you mention, in his LOS for the Samsung Galaxy S7 - because the very most of us S7 users do not need these functions.

And just, because Ivan does his rom, as he thinks to do it, that does not mean, that this is no LOS.

 

[netra3441]

Well, folks, I guess, we maybe have an issue now with LOS 20.

@Ivan_Meler could you please check that?

I had charged my S7 up to 100%.

After that charging I did not used it.

Since the charging up to 100% the S7 lost 22% without doing anything.

No apps working in the background.

While just typing these lines in an editor, the S7 lost 2% of battery... adding these lines in here, costs me alltogether 5%...

Something really looks to be wrong...

Hint: the S7 is cold, no warm battery.

check your gapps, ive noticed that nikgapps caused significant drain without reason after being dirty flashed over for a long time, either that or battery calibration got messed up

Hey Ivan,

thank you!

I read about, that NikGapps have issues more and more.

When I want to change from NikGapps to OpenGApps, then this means to make a complete new installation, right?

Yes babe... that is, what I like really...

Hi Ivan,
I have the same issue since february release, i thought it was my battery who was out of order, but i see that i'm not alone. I use LOS 20 since december 2022 and everything was good so far.
Thanks for your analyse.

Byt he way : great job, i use your rom since 2020 !

If you wipe system partition, gapps are also gone and you can change to open gapps. Please correct me if i am wrong.
