You should generate logcat right after the crash. Check post #3 how to report bugs.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Hmm interesting. Anyway it isnt worth to patch it in my case and i dont have knowledge for it lol
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Last_kmsg is only useful after an random reboot. Logcat & dmesg is for app crashes.

@Driieel how to reproduce the crash ?

What is crashing ?
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
I am noticing that, after I switch from my "performance plus" profile to my "performance" profile, cpu-z app still shows CPU speed based on what's setup in "performance plus". How can I best report this so you can check?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Try to fix permissions in debug menu of the full version app.
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
Just did it, same issue persists unfortunately.
[Samsung Galaxy S8 & S8+ Cross Device Development] Driieel:
I do not know exactly. I'm using it normally and sometimes it starts to crash out of nowhere, then it goes back to normal.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Using latest kernel and app ?

Which freqs you use in performance plus ? Then i can test by myself.

In addition you can trigger the issue then generate logcat and post it here.

Yeah, what is crashing ? What do you mean by crash ?
[Samsung Galaxy S8 & S8+ Cross Device Development] Driieel:
I'm using the latest kernel and app. I use loading at 3000ma, up threshold at 45, for gpu and cpu, DVFS at 100% with the default frequency of the S8.

When I talk about crashing, I say the S8 turns into a Galaxy pocket for a few minutes. I will try to collect information and activate the problem to try to send you more information.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
DVFS 100°C maybe unsafe, try with 95°C.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
i think that not crash that like much loading when fresh open from pocket or not use the phone like 1 hour or 30 minute or when you sleep that took a time to load maybe that from IO of rom i guess
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Not having issues here, also since removing brevent and just closing apps with eg ccleaner helps prevents having slowness. Also a good thing to do, go not above 42c on battery temp while charging becus else the phone is gonna throttle down the performance.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I never got 42°c battery temp that always 36 to 40 higgest i ever use maybe i reach 42 when use it under sun for look map
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Okay, well i use 65c dfvs and power save profile, and for charging i use max charge current. but still it gets too hot sometimes, especially profiles with a higher clock speed😅
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I think because i use 65 dvfs maybe but that slow i feel when the phone is like 28 or 29 °c when press power buttom you can chill a while for the loading and ready to use like ussually
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Hmm maybe trying a other swappiness & page cluster and read ahead value. Anyway i guess i use more of my phone like gpu and cpu with twitch or youtube but normally with light tasks my battery doesnt rlly get hot nor my cpu and gpu.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I double the battery but i gpt just this value after a few of charge and discharge

Settings i use

Save profile

Dvfs 65°C

Swappiness 195

Read ahead 8kb

Page cluster 0
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Hmm okay, how did you double it lmao?
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Paralel the battery to battery board
[Samsung Galaxy S8 & S8+ Cross Device Development] Driieel:
@ace2nutzer I lowered the DVFS to 95 and now it looks good.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Okay then it's clear now. Thanks for your feedback.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Hi dev i have question about

There is a new update ?

And when gpu can be more 572 ?

And undervolt tho ?

That it my question hehe
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I talked with Ace a few times about this and from what I can tell, neither are coming anytime soon. Why? Because Samsung is really great at NOT giving what we want.

G960X and N960X devices have same issue.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
There is nothing to update so far, everything works good. If I release further builds then only if I can manage to introduce higher OC ability. Yeah it's still on my to-do list.

Biggest problem is that we havn't source code for PLL and voltage regulator, but I've one last idea that could make it possible to edit the whole clocks and voltages of this SoC. If not then we can forget, so there is little hope. And if that'll work, that simple hack could be applied as well to OC other phones like S7, S9, S10 and so on.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Yeah i think same samsung make difficult to full control of the SOC :")
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Not only to get control of their soc, to unlock and root the phone aswell like with s10 and above😂
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
In my opinion, phone rooting died in 2018 as far as Samsung is concerned. They made it impossibly hard and disadvantageous to even unlock the device
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
OK guys, what do you think when you hear this track:

Let me see later who was right ... lol
[Samsung Galaxy S8 & S8+ Cross Device Development] Badger50:
I'm thinking I'm too old to know what the track is from, and it's time to go to sleep! ;)
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah it was 4 AM for me. It doesn't matter how old you are, it has something to do with this project.

I can't give more hints, otherwise it's too easy. 😃

Yes and no, please read again what I wrote.

Yeah, you are on the right way.
[Samsung Galaxy S8 & S8+ Cross Device Development] Samsara69:
Hello.

I am using NX kernel because Drivedroid compatible.

Must be rooted.

Can anoyne please try Drivedroid working with this A2N ?

apk is here https://www.drivedroid.io/#changelog

What about if just flash A2N over NX kernel without wipe?

I want try moisture warning disable.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Hello !

This should work, Drivedroid should work too, but I'll check it later. if not just flash your old kernel and report it here please.

@Samsara69

Edit: DriveDroid works properly.
[Samsung Galaxy S8 & S8+ Cross Device Development] Samsara69:
Thanks for your help.

Can i flash your kernel whitout wipe ?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
You are welcome!

Sure you can.

But for best performance, wipe apps cache and in recovery wipe dalvik-cache. All your apps and settings will stay on place.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Btw the last idea I had it really worked ! :oops: Initial GPU OC @ 839 MHz.

To be continued ...
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I hear this track is like wake up from long sleep make the world better to for al mankind
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
WOAHHHHH I HOPE I CAN USE IT I WANT GAMING WITH MY KILLER COOLER THAT CAN KILL THE HEAT OF THIS PHONE
[Samsung Galaxy S8 & S8+ Cross Device Development] oleg vegas:
a certain sergey on the 4pda website knows how to regulate the voltage of the GPU, I asked if this is possible with the CPU, he said yes, but you have to turn off the hotplug and this is not very effective
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Thanks for the info, but I'd already hacked GPU voltage by myself.

Works stable @ 839 MHz. But actually I'm stuck at RAM OC. Stock max_freq is 1794 MHz. Added voltages like I did for GPU, but it doesn't work because it uses devfreq driver. If you could ask him how to make dvfs_mif freq @ 2093 MHz it would be great. Voltages are assigned, but phone doesn't boot if I set max_freq = 2093000.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
OK Guys New Build is Up !!

Changelog

Kernel V. 2022.06.12

GPU: updated voltage table - stable OC up to 839 MHz !!!

[Samsung Galaxy S8 & S8+ Cross Device Development] PIKO!!!:
Thanks for your hard work!!!
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Yes GPU!!!!
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I AM BACK !!!!!🤣🤣🤣🤣
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
So GPU @ 839 MHz work stable for you ? Btw I've also optimized CPU voltages, so maybe you can get higher stability for CPU OC, but in my case I wasn't able to run 2,8 Ghz stable. Highest stable CPU OC is 2,7 GHz for me.
[Samsung Galaxy S8 & S8+ Cross Device Development] lautirio1:
Thank you so much for this kernel, it works incredible.

The only thing that's not working for me is GPU @ 764 Mhz (When used at 100% it starts to show artifacts) and GPU @ 839 Mhz (When used at 100% just crashes the video driver and have to restart the phone).
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Thanks for your report ! - It's just initial real GPU OC without voltage control.

For me it works stable @ 839 MHz.

Well, then I'll try to provide GPU voltage control.

Actually it should be possible to add +0.1V to the GPU, that should make it stable at 839 MHz for everyone.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Okey i will wait but in case when benchmark use antutu on gpu test i got some lag cause system ui not responding
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
New report

GPU 764

CPU B 2.6 L 1.8

Swappiness 190

Read ahead 512

Cooling? The name is goes brrrr
[Samsung Galaxy S8 & S8+ Cross Device Development] lautirio1:
Ok, so i was testing with some Antutu and Geekbench benchmarks and discovered something.

The thing that was hurting my performance and video driver on GPU @ 764 MHz was actually the B.CPU @ 2704 MHz. So when i turned it down to 2652 MHz it started working flawlesly at GPU 764 MHz (It still crashes at 839 MHz).

Now im geting really good scores on benchmarks and, for example, on Asphalt 9 with fake Exynos 990 CPU (For better graphics and 60 FPS) on standard settings, works at a constant 60FPS with some drops here and there.

Allso temps are really good and never thermal throtles without a cooling sistem.

My settings are:

B.CPU: 2652 MHz, Boost Enabled, Up Threshold 75%, 95°.

L.CPU: 1898 MHz, Boost Disabled, Up Threshold 90%, 95°.

GPU: 764 MHz, Boost Enabled, Up Threshold 60%, 95°.

Thank you again for this amazing Kernel, and sorry if my english is a little rough, my main language is Spanish
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
How do make fake cpu info ? Can this apply to other game
[Samsung Galaxy S8 & S8+ Cross Device Development] lautirio1:
Yes you can, I use gltools with NFG Multi Crack, look for a tutorial on Youtube, it´s relatively easy
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
@ace2nutzer do you know by any change how to fix the auto disable of accessibility services like from appmgr and ccleaner? Becus it turns off after a while and its rlly annoying to turn it back everytime i use those appa to clean or to close apps, dont know if it its a bug in android 9?

Edit: seems like it happens only when force closing appmgr and ccleaner they loosing accessibility services becus it then turns it off.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Try to convert them as system app.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Good idea, ill try that and let you know about the results
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Nope, still disabling the services after i force stop them, guess its a bug in the android 9 system.

Edit: it holds them enabled when rebooting and when im not force close them, so guess i shouldnt them force close them. Anyway i blacklist appmgr in ccleaner and should fine now.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah, that's normal behaviour indeed.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
I forced close it becus it was using high cpu after i quit out of it, idk what it is doing but i reported it to them.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah, that's probably a bug, I hope you posted also a logcat, otherwise they can't fix it.
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
Hey ace2nutzer what rom should i use with this kernel im currently on pe12 plus for the s8 plus (pe is pixel experience)
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
Stock or what are other good android 9 roms for the s8 plus???
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Test yourself, personally I use Samsung stock ROM with TWRP and this A2N kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
K thanks.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Well... i forget that😅 anyway if they ask gor it ill attach it with the reaction
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
hey ace2nutzer can u please tell me firmware used for stock rom please my parents will kill me ...
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Wut use DUD1 firmware
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
yes but ill try others are stuck on recovery
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
What you mean stuck
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
i start it first it fasiled at syystem and now stuck at recovery and doesnt write system also where do i find dud1 i only found dud3
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Ouh i see if you have only dud3 doesn't problem you need see red warning text
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
what
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
twrp is a fking lifesaver fam
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Yup that can be sometime flash stock firmware most of saver
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
icant flash stock its stuck at flashing recovery i tried out horizonrom but it doesnt really good to me so im gonna try out hadespie stock s8 plus also my grammars bad cuz im hungarian sry for that
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@XkingH(newbie)

You need to download latest stock firmware from sammobile .. choose your phone model and then your country. Then download odin and you need Samsung mobile USB driver. Then you can flash the firmware with odin. Phone need to be in download mode, press volume down + power for that. Of course you need am Windows PC or notebook.
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
Yes,i know but when i try to start flash it makes boot.img or idk what and then its stuck at writing recovery.img
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
And btw sammobile doesnt have hungarian version my device was made in vietnam
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Then you do something wrong.

Just choose a most appropriate country, it's not a problem.

You need to load all the tar files into odin. Use the recommanded odin version from sammobile. Maybe you do something wrong with the pit file or some settings in odin. You only need to enable "auto reboot" and "factory reset time". If you have still problems, you can record a video how you set up odin, then I can tell you what you are doing wrong.
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
I had 3 phones in past as tests all succed on odin idk whats with my s8 plus also if you have time can u please do that video...Thanks!
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
K ill do the video but... How since im not an adult and i have 1 phone 1 laptop
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
ill do it from my moms phone later
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Okey now you need spare time much spare time to do that and have nice learn
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
I didnt send cuz my moms working ...
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Is odin giving errors or something? So yes, try a other version. I got also issues from a particular version with my previous phones, so i recommend to try a newer or older version of odin.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Well i got my Galaxy S21 FE 5G SM-G990B delivered today😄 also there was a promotion by samsung they give away a JBL Flip 5 away with this phone, but only thing i have to wait 11 weeks till i have it😑
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
@ace2nutzer u r and all who helped me in my situation thanks u all are lifesavers im rocking the stock android 9 thank u all my pafents aint going to kill me now...THANKSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
and im gonna use your kernel cuz its nice lol
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
and buy the kernel app to boost dev work hehe
[Samsung Galaxy S8 & S8+ Cross Device Development] XkingH(newbie):
Yes i would even give the dev like 100 dollars or even 200 but i cant i dont have a credit card ... and my mom doesnt trust these apps... sry for that
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@XkingH(newbie) I can give you 1 week test access to all premium features, so that you all can see if it's worth its money. Honestly the current price of 4 € is just a joke.

The real value of this app is around 20 €. If you want to give it a try, just tell me your google play (gmail) e.mail address, then you can download the full version for free.
[Samsung Galaxy S8 & S8+ Cross Device Development] Arnz09:
How'd you do that? Would you mind sharing it? I couldn't find any tuts on yt.
[Samsung Galaxy S8 & S8+ Cross Device Development] lautirio1:
First you need Magisk root installed.

You need to install Riru and Riru-LSPosed from the module repo on Magisk's app.

After you install them, restart your phone and when it finishes it will ask you to add the LSPosed icon to the Start screen, tap on yes.

Then you can install the GLtools apk from the official page and the NFG apk from the Github repo.

Finally open te LSPosed icon you added to the home screen, enable the NFG module and tick the GLTools option.

The tricky part is that you need to open gltools and you'll see a coin icon on the top right corner, close it, open NFG app, activate the crack, soft close GLTools, open it and you should see a crown icon where the coin was.

If thats not the case, close gltools, open nfg, disable the mod, soft close, open gltools and repeat the crack step.

If it still doesn't work, uninstall gltools, reinstal it and repeat the crack.

I hope it helped you, good luck!
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@TechNoobForSale likely you still didn't notice that real GPU OC is now possible, therefore I call you since you want to break again the world record of benchmarks scores!

Anyway, first initial GPU OC release was not fully stable for everyone, and therefore I've uploaded here a test build with higher GPU OC voltages. Let me know guys if you get 764 + 839 MHz stable now.
[Samsung Galaxy S8 & S8+ Cross Device Development] spdrfx:
Hello guys, i get the same result with OC-ed GPU, and the stock one in seascape benchmark. (https://play.google.com/store/apps/details?id=com.nature.seascape&hl=hu&gl=US)

Can anybody test it for me? Thanks,
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Just test with 3D-Mark, Geekbench or Antutu.

Also don't forget GPU OC only with A2N full version possible and don't forget to increase CPU / GPU DVFS temp at least @ 95 °C for best benchmark results.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Seascape is pointless for GPU benchmarking
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Ace just revived S8 by unlocking the GPU OC >572. Only the God AceNutzer could possibly do that. I'll test soon enough. Thanks for your hard work.
[Samsung Galaxy S8 & S8+ Cross Device Development] spdrfx:
ace2nutzer

I just want to thank you for your hard work, its really amazing, you can achieve this gpu OC thing. I tully believe, that is not possible :)
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
For some reason on the stable GPU OC test Kernel, at the old 572MHz frequency, I’m seeing lower scores than before. Maybe A2N kernel manager needs update?

So far I’ve only tried Icestorm Unlimited. I’ll try slingshot for more reliable GPU testing. But this would indicate that CPU is underperforming, need more testing, might be wrong.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Scores seem perfectly fine in Slingshot Unlimited. I’ll test above 572 in a bit.

Ace did you change something in cpu frequency scaling? Because that would explain low ice storm scores
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
So, I’ll say that for the Summer I am not a reliable source of peak performance figure due to the high ambient temperatures, which make my tight testing environment impossible to realize. I recommend people rely on @rtyuakatsuki for peak performance figures and records break thanks to his direct cooling.

Nonetheless, I can still provide a baseline and I could give the guy a tip or two on optimizing a phone for benchmarking,

For now I tested Slingshot Unlimited only, as I think it’s a test that is already tough enough for this device. I could use GFXBench too, but that’s for later.

So following this, I’ll post the results.

Note: Tests are conducted at stock CPU frequency, as it could never end up being a bottleneck at such low frame rates. Also I tested only up to 764MHz. As at said frequency, the temps get absolutely mental and the GPU throttle at 683MHz.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
(764 throttled to 683MHz briefly).

Additionally, I attached Snapdragon 835 (Nokia 8, 710MHz GPU) and Exynos 9810 (GPU OC @598) results for comparison.

Note 2: Snapdragon 835's Adreno 540 is not as fast as you would give it credit for. In Slingshot Extreme the true power of the Mali G72 shows up and wins by a moderate margin. S8's Mali G71 however is outclassed.
[Samsung Galaxy S8 & S8+ Cross Device Development] oleg vegas:
can i try to test the app? i just don't have a bank card and i can't buy this app
