Hi everyone,

I have a few questions regarding this Kernel.

1. Can I flash it without deleting my data? If so (if someone has tried), is it stable?

2. Will some apps get blocked because of the change of the kernel? I tried to use the BeIN sports app with my subscription on a custom rom on another phone but it was blocked. Has anyone experienced any problem with any app permission?

3. Does the app block the official Samsung updates of the device? I'm still looking forward to get the last security updates.

4. Is this kernel worth it? (the most important question)

My general point is do we get the benefits of the kernel without trading the stock "benefits" and features and compatibility with this kernel?

Thank you for your reading me.
[Samsung Galaxy S8 & S8+ Cross Device Development] Orangelelo:
here is this
[Samsung Galaxy S8 & S8+ Cross Device Development] Inasbae:
1. Yes, you can flash this kernel without delete /data

2. Hm, usually some applications reject root devices, but you can fix it with magisk hide (of course you have to flash magisk)

3. Well, unfortunately s8 doesn't get any more updates from Samsung except for the security patch, which usually every custom ROM is always updated

4. Very worth it. And dont forget to buy/install the kernel app (A2ñ control). Because you need that to control the setting of the kernel and device :)
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I need one with the oc kernel and one where 2.65ghz is not stable .. like a2n kernel. From the same phone ... otherwise it is too hard to grab some useful Information.
[Samsung Galaxy S8 & S8+ Cross Device Development] leonidasZ953:
Hello mate, when i install a2n kernel for my s8+, without any maximum limit settings..When I open one app I see some artifacts on screen.. when I install stock kernel is fine.. I play with settings(safe) and still is same..Any help about this?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Screenshot ?
[Samsung Galaxy S8 & S8+ Cross Device Development] Orangelelo:
oh it mean i have to degrade from aosp 10 to stock 9.

ok tomorrow i will post.
[Samsung Galaxy S8 & S8+ Cross Device Development] leonidasZ953:
Its impossible to take a screenshot..its 1 sec only..not more
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
If it's not too much work ... but i guess you do it with twrp Backups .. right ?

OK i'll try to fix in next build.
[Samsung Galaxy S8 & S8+ Cross Device Development] Superlion721:
Thanks, I really appreciate the feedback.

What has been your experience so far? How has it improved your s8?
[Samsung Galaxy S8 & S8+ Cross Device Development] LuciferEx:
Hi, I got to say I have tried many kernels and this is the best one so far imo. I bought the pro version of your kernel control app. I have been using your kernel for months now. Oh btw, the most recent a2n update makes the app crash when trying to go to the Power settings. I have a question which was probably already asked but I looked through the comments and I could only find settings related to gaming. What are the best settings for multitasking, fluid UI, fast loading of apps etc. I want to focus the max performance to the productive side. I don't game on my phone and battery isn't a problem since I have a external battery case.
[Samsung Galaxy S8 & S8+ Cross Device Development] The_System:
I'm excited for the release of the LineageOS Kernel. I bought the app while I was still using a Samsung-based rom and it was by far the best customization I have gotten from a kernel. Been patiently waiting for LineageOS support after I discovered that my device performs significantly better with with OSs based off of LineageOS.

I can see you take pride in your work. Keep up the good work and thank you for the kernel!
[Samsung Galaxy S8 & S8+ Cross Device Development] Orangelelo:
Here is last_kmsg of a2n kernel stock custom pie rom(alfa ux v1)
[Samsung Galaxy S8 & S8+ Cross Device Development] keyboardhouse:
gonna try your settings for gaming, im glad someone sharing their gaming settings on kernel :good: so far this Kernel is the best for performance and gaming, honestly been looking for note 9 kernel but all of them are like a stock kernel the different is they put "performance or something like that" but it actually like the stock kernel with different built name, even my S8 with this kernel beat my note 9 easily on performance
[Samsung Galaxy S8 & S8+ Cross Device Development] maej72:
[MENTION=5840412]ace2nutzer[/MENTION] hey, can you make a 40c or 39c version since a lot of us want to keep the battery temps down.

Thanks for your hard work, keep it up
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
The BIG Cores are used for the foreground tasks with this Kernel. Whilist the Little ones are for background. So, if I reduced the amount of the little cores that will be used to say, only the number 0, will I get more overclocking headroom for the big ones?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
CPU Cool Freq = 1807 MHz

Performance Plus

zRam size 25 %

It depends on your settings. Instead to use 3000 mA use 2200 mA or instead 3500 mA use 2600 mA. ;)

Nope, little CPU has nothing to do with BIG CPU.
[Samsung Galaxy S8 & S8+ Cross Device Development] Superlion721:
Hi all,

I have a question which I'm not sure has been asked.... Will rooting and flashing this kernel delete Knox? And if so is it irreversible?

I'm asking in case I want to use trade-in to get a new phone in the future (like on Black Friday if something good comes up).

I'm on Exynos in case you wonder.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
How did you manage to make the M2 Cores stable at 2496MHz and the A53 Cores stable at 1898MHz though? Did you manage to force the maximum voltages on all the frequencies or something like that? Currently I've managed to get 2496MHz with all 4 M2 Cores enabled, 3 Cores at 2574MHz, 2 cores at 2652MHz and 1 core at 2704MHz. Running even 1 core at 2808MHz consistently crashes the phone.
[Samsung Galaxy S8 & S8+ Cross Device Development] God's Bro:
what happens if i set little cpu set to 0 and big cores to default figures, will the heat reduce when gaming?.. still i get fps drops when enemies are around on pubg.. Im sorry but i see no difference compared to previous update.. i guess this is the maximum performance we can get from our s8.

I cant set cpu dfvs to 2002mhz, i can only game for 10 to 15min phone reboots.(my room temp is around 30- 33 and phone idle battery temp is around 33 to 34) and other thing does performance improve when ac current is increased? my current settings are

ac current 1800 (cant increase further it heats up alot 40 to 44)

battery idle on

big max freq 2.4 / suspend 2.4

cpu dvfs 1.8

big 'cpu set' default

little max freq 1.6 / suspend 1.6

little 'cpu set' default

gpu 572 / dvfs disable

i asked about this once too from u a2n .. a lag free gameplay.. if u can for the last time can u give me a solution(best settings):(:good:
[Samsung Galaxy S8 & S8+ Cross Device Development] Inasbae:
don't lower the little core too low, it will make Big core stress and make more heat.

And for your Game profile, if you cant use 2.4Mhz on Big core, just set to standart Frequency (Big Core to 2.3 and little to 1.6) and CPU DVFS to 2.3Mhz.

I think you play pubgm while charging right? Battery idle is usefull, but just set the max current to 1500.

And about heat, its normal if you get 42-46c for playing pubgm while charging with this old phone :)

You need a fan cooling too for that

(like me, use a fan when playing the pubgm :p ).

And i think the latest kernel have more heat because the dev apply the Boost frequency on Big and Little core.

(On previous version, we just need a Touch boost with little duration to reduce the heat, because i think Boost Frequency is useless and make more heat)
[Samsung Galaxy S8 & S8+ Cross Device Development] Orangelelo:
have u found out any useful with both last_kmsg
[Samsung Galaxy S8 & S8+ Cross Device Development] God's Bro:
Thank you for your response:o .. i can set it to 2.4 but at the same time if i set cpu dfvs to 2002 or more phone reboots.. ill try your configuration:good:
[Samsung Galaxy S8 & S8+ Cross Device Development] Orangelelo:
set phone little 1898, big 2.496.gpu 572 mhz dvfs on.

cool frequency default. u will get good performance without reboots. donnt go far because phones physical material (and over compactness) doest gets leave heat out of device so cooling speed is very less. so its adds up more and more heat while heavy usage.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I case you want to put your phone in orginal state incl. all the knox features you just need to flash latest stock ROM with ODIN.

But warranty bit will be triggered, but your warranty is only void on certain countries ... google it.

There is no magic, it depends on your hardware and room temp ...

Nope, as i already said, little cpu has nothing to do with the heat of big cpu. You will only slowing down the performance if little cpu runs with less cores or smaller freq than stock.

Nope, it's still possible to increase speed ! - Wait for next Update.

I cant set cpu dfvs to 2002mhz, i can only game for 10 to 15min phone reboots.(my room temp is around 30- 33 and phone idle battery temp is around 33 to 34) and other thing does performance improve when ac current is increased? my current settings are

This already good ... zram try 25 or even 50 % .. and LMK: keep the default.

Next Update will increase total speed ...also for games.

Real hardcore gamer :D

Only on BIG.

Yes and no, it's minimal, but next build will be much better.

Didn't had the time so far, sorry :(
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
No no look. I am 100% sure that in the previous releases of the app and Kernel the 2496MHz and 1898MHz frequencies were labeled as "unsafe" whilist now they aren't anymore and they are actually stable. And previously they weren't, not to mention the hardcoded Performance Plus profile is no longer unsafe too.You must have done something. And I would like to know what you changed because I'm like really curious. That's what my question was in case there was a misunderstanding.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
OK it was more a misunderstanding, sorry.

Honestly i didn't change anything that could that much significantly on stability side.

I've only removed the "unsafe" label on certain freqs because many users reported that little CPU 1898 and big 2,5 GHz works stable and in my case too.

Only significant changes for stability was made in Kernel version 2020.08.06.
[Samsung Galaxy S8 & S8+ Cross Device Development] Superlion721:
Thank you for your reply, that is good to know. My warranty is already due though as I've had this phone more than 3 years ago. My only concern is for features like Secure Folder for example and also if I want to trade-in the phone with Samsung. I'm not sure if they check if Knox has been triggered or not.
[Samsung Galaxy S8 & S8+ Cross Device Development] RAGO143:
will this work for ANDROID 11 ROMs too?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I don't know, but everything will work like original once you flash a stock rom with odin, and i believe that in many countries they don't care much about knox bit.

You serious ? :D i didn't even added support for 10 yet.

Performance improvements was meant that the default settings are now for better performance. So it was an improvement for users that have only the demo version. So for you Guys with full version the speed was same if you was using more or less the same settings .. (boost, touch duration time ...)

Next Update will have higher speed + better battery lifetime for both demo and full version. You will see it in benchmarks.

Stay tuned ...
[Samsung Galaxy S8 & S8+ Cross Device Development] Superlion721:
I really appreciate your reply and your time. I think I might give it a try. You tell us to delete data from the phone before flashing but I can't be bothered with doing it for now.

Will flashing the kernel delete my data by default or will it stay there? (Obviously, I will backup my data as I always do).
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
If you have stock rom without TWRP then you have to wipe data ... in order to remove forced device encryption by samsung.

You can't flash the kernel without TWRP. And the kernel will not delete your private data automatically ... but it's needed to perform the step: wipe data ... by hand in TWRP recovery ... so once you do this, all Apps + settings + internal sdcard is deleted ...

Later the Phone is like in factory reset .... like a new phone ... u know ? The Setup Wizzard will appear and here we go !

You can use this kernel with stock rom ... so basically in the end everything will look like before ... only difference is the improvements in speed, battery and new features u will get.

It's even possible to flash a (patched !) stock kernel .. after all that ... without the need to wipe data once again ....

Because as long as you flash patched kernels with removed forced encryption, your phone will not be locked on boot and so on.

And thats why i do provide also a patched stock kernel for refeences only ... to find or helps to track bugs.

I agree that it sucks to configure the whole Phone ... needs some time of course ... but it's really worth it. :o

You could even try to flash this kernel incl. the Full Version (not a free app) ... and then trying to sell the phone for more money since this project increases the value of the Phone. Just an idea. But i'm sure that you don't want to painfully sell a great phone running this kernel :D
[Samsung Galaxy S8 & S8+ Cross Device Development] Superlion721:
Indeed, the goal is to give a second life to my beloved S8 although I'm starting to eye a few phones out there.

I wish their was a way to back up everything on my phone especially app data as they do on iPhone. Then the process of flashing would be much easier. I just hate having to backup 64gb of internal along with 64gb of external as they're both full at the moment ?.

Your project looks very promising though. Backing up takes time and I won't be able to do it quickly as I'm quite busy lately. By the time I finish it and ready to flash it, there might be a stock rom based Android 10 for our S8 (I heard it was an upcoming project) or maybe I'll be ready for retirement or even Coronavirus might be gone lol (we all hope).

I'll keep following your project(s) and hope I'll be able to flash it and give a feedback here.

Cheers mate!
[Samsung Galaxy S8 & S8+ Cross Device Development] leonidasZ953:
I told few days ago, something with glitch..I found it...

The glitch is coming from when use WQHD+ if change with FHD+ its fine ??
[Samsung Galaxy S8 & S8+ Cross Device Development] rostifaner:
I also notice that wqhd+ is buggy, especially if I use auto rotate for watching videos in fullscreen mode.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes ! That's right ... i've already reverted relevant changes:

https://github.com/ace2nutzer/Samsu...mmit/feb121f73d0297c1e2c97dc174fd6b94ddc7a78e

So it's fixed in next build guys.
[Samsung Galaxy S8 & S8+ Cross Device Development] leonidasZ953:
Any news about update?? ??
[Samsung Galaxy S8 & S8+ Cross Device Development] steveman29:
Are you going to enable higher gpu speeds again in the next version?

Στάλθηκε από το SM-N950F μου χρησιμοποιώντας Tapatalk
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes of course ...

Release is ready and i'm just testing if it's stable.

So far no issues, so later i'll upload.
[Samsung Galaxy S8 & S8+ Cross Device Development] Orangelelo:
wow. just waiting for 2002mhz stable and 2.65 stable

last_kmsg helpfull?
[Samsung Galaxy S8 & S8+ Cross Device Development] God's Bro:
Why the thread so silent:rolleyes:

Whats up with the new update?:o
[Samsung Galaxy S8 & S8+ Cross Device Development] User_99:
Maybe because all works very smooth with this kernel ;)
[Samsung Galaxy S8 & S8+ Cross Device Development] predict9:
yeah it cant get better i think
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
OMG forum theme is completely screwed up ! - They fixed it later.

as for the Update: i'm still working on it ... i'll upload new update when i'm done to fix bugs and when everything is very well optimized.

Next Release is very interesting, because it'll fix many bugs and will improve everything on both free and pay version.

So it's not all here, big improvements are on the way.

Please be patient.
[Samsung Galaxy S8 & S8+ Cross Device Development] jowl_tnt:
On latest 927 I have problem with miracast.

After some hours stop working and make phone stuck everytime trying to connect.

I have to reflash rom, not just kernel to make it work again.

No problem with 827.
[Samsung Galaxy S8 & S8+ Cross Device Development] God's Bro:
Take your time and make it better :D:angel:
[Samsung Galaxy S8 & S8+ Cross Device Development] LuciferEx:
I'm having a problem, YMusic keeps getting killed when multitasking. The music stops.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Multitasking will be better on next build.

Anyway, make sure to disable all battery optimizations from Android ROM Settings --> Battery.
[Samsung Galaxy S8 & S8+ Cross Device Development] tahmid8464:
Tried installing 5/6 time on S8, but system didn't boot. I had used the previous version, that one had worked. My phone was rooted, flashed a2n kernel with magisk after formating data and also without formating. Each time bootlooped
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Hmm strange ... maybe you didn't wait enough ? need to wait at least 10 minutes.

Try again flashing latest kernel ... if it doesn't boot after 10 minutes, then flash previous version and grab last_kmsg with the pre-installed A2N Kernel App (red-symbol) see Post #3 how to grab logs.
[Samsung Galaxy S8 & S8+ Cross Device Development] predict9:
hhmmm no updates anymore ? its been a week since u said the next build is coming very soon..sorry if i made u angry.
[Samsung Galaxy S8 & S8+ Cross Device Development] Inasbae:
I want to download older apk, how? Because i need some cpu setting on 2.7 apk version..
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Of course this Project is still maintained. But i was also saying "if i don't find more bugs or if there is nothing to optimize"

Because that's actually the case ... i had found several bugs and many things that i can still optimize.

So far everything seems to work fine, later (i hope this night) i'll release new kernel, kernel control apk and tuned twrp.

It's a big update with big improvements, so i think the long waiting time should worth it for you Guys. :cowboy:

I don't think so, the things you are searching will be completely redundant in coming release.

Flashing older apks versions, can cause FC.
[Samsung Galaxy S8 & S8+ Cross Device Development] Inasbae:
No, i want to use older build too..
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I'm sorry but i've only latest Version.

Maybe you can find it over Google search.. but be careful because many of them that are not original hosted from me or Google can contain Malware or Virus.
[Samsung Galaxy S8 & S8+ Cross Device Development] Inasbae:
Ah ok nice work. Thank you:D
[Samsung Galaxy S8 & S8+ Cross Device Development] predict9:
sooooo our s8 aint limited yet lets gooo keep up broo:good::good:
[Samsung Galaxy S8 & S8+ Cross Device Development] sadmanpoth49:
I had downloaded the kernel about a or two weeks ago. I was then using AOSP. Today I flashed the stock firmware. So went to install this kernel. But didn't seem to boot up on S8. "Samsung Galaxy S8" screen appears and reboots. This goes on.
[Samsung Galaxy S8 & S8+ Cross Device Development] khanhbang2013:
flash the kernel again, and flash magisk if you want root, generally flashing the kernel twice is ok
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Ace must be working on something big this time. It's been over a month. Take all the time you want! If this stuff's gonna be big, then we'll wait. after all, this is the only kernel that can satisfy our benchmark mania lol
[Samsung Galaxy S8 & S8+ Cross Device Development] sadmanpoth49:
Does that means i'll have to flash magisk twice as well?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
After restoring a backup ... it's better to flash kernel and then magisk.

But usually not needed if you restore

Boot

System

Data

But again if it doesnt boot .. the better to wipe cache and dalvik and flash kernel and magisk.
[Samsung Galaxy S8 & S8+ Cross Device Development] God's Bro:
Alright:o
[Samsung Galaxy S8 & S8+ Cross Device Development] Carlos 56:
I miss the old version that you could change the loading speed
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
What ? - Did you mean up_threshold ?
[Samsung Galaxy S8 & S8+ Cross Device Development] Inasbae:
I think yes, i face too much Heating problem on latest build because the cpu frequency is too agresive (Because you active the Boost).

Its better to have option for that, like older apk.

And its better if you can bring back input booster touch frequency setting.

Its just my opinion :)
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Input booster will be completely disabled on next build, because we'll switch to ondemand governor which is much faster than conservative gov .. so that it makes input booster fully redundant !

btw you Guys never faced/reported that zRam is not stable(random reboot) on this kernel ?

Honestly i also never faced it, because i'd never used it, but now a few days i'm using it since i want to enable zRam 25 % by default.

Now i'll try to fix it and hopefully this was the last bug ! :highfive:
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
No. I have been using the Zram setting at 25% for a very long time on my Samsung Galaxy S8 now. And it never brought random reboots at all. And to be honest with this Kernel I never had a random reboot to begin with. I'm currently on an older release of the Alexis ROM. It isn't even stock One UI yet it is very stable. Don't worry about it I guess.
[Samsung Galaxy S8 & S8+ Cross Device Development] Inasbae:
Ahh i see that on your github :)

I just hope that ondemand will be stable enough in the next build.
[Samsung Galaxy S8 & S8+ Cross Device Development] God's Bro:
You said the update going to release very soon.. but still no sign of it.. Can you tell us a exact day or month or year that u going to release the next update?.. sorry for being rude.. so that if u give us a release day we can check on that day..:rolleyes::good:
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
So far it works great .. but it's just 14 hours ago that i'm testing it.

Same for zRam random reboots ... looks like i've found the culprit. :o

Yeah but it's hard or almost impossible to say the exact date of the release. Because i'm not only enabling / disabling Governors in defconfig (like some other dev here) and then writing in changelog:

"Optimized battery life and speed"

Optimized this and this ....

Then you check in his GitHub and there is almost nothing significant.

I can't say the name otherwise this post will be deleted you know, but i think many users knows who i mean. ;)

Anyway, not a big thing, every of us was a noob. :)

This Project is hard/real development.

Optimizing + fixing bugs can take a lot of time and many grey hairs and nobody can say how long it takes to fix xy feature or so.

Because it's done when everything is fixed and works fine. :o

Actually you can check every 5 hours for new Update ... or better to simply subscribe the thread then you get notification when i'll update Thread Title about new Release.... so make sure you subscribe and you have enabled e.mail notifications.
