No reboot for me after 1 week i use light rom is very stable and get 32k + on AnTuTu
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
32k seriously?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I think he meant 320k lol
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
I got only 261k with antutu, but my settings werent fully optimized yet etc so yea, room for improvement😄
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Yeah i think like that but how ? I only can reach 313k
[Samsung Galaxy S8 & S8+ Cross Device Development] Triger972:
Yes 320k sorry lool
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
This has to be a joke right? 😂https://xdaforums.com/t/fvp-forum-violation-passes-now-available.4424853/
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah, 1. April.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Highest score i get with max stable overclocks etc is 307k, guess to squeeze out the last bits of performance is try to benchmark on a clean rom and adjusting different things in build.prop to get more performance with this build or test it with different roms😄😄
[Samsung Galaxy S8 & S8+ Cross Device Development] bntnja:
504 hours pass, no reboot yet. Let's see if I can do 1000 hours w/o any reboot!
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
720h would be already pretty good = 1 month! If it works stable for 1 month, then theoretically it should work stable even for 1 year. But who will manage to never run out of battery, hehehe.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Guess the rom will be rather crash or cause issues without 1 month of rebooting instead than there will be a kernel crash in meantime😄
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
What will be in the next release @ace2nutzer ?
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I am waiting for it what next update and surprise
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Im waiting for it, but im just curious whats in the next release hehe😄
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Same me too hehe

And dev what next update 😁
[Samsung Galaxy S8 & S8+ Cross Device Development] psygenius:
I'm having an issue with the app not validating it's license. I've checked I'm on the latest version of both the app and the Play Store. Is there something else I can try?

Thanks

Scratch that, ignore the above. Fixed with a manual download of the Play Store.

Cheers

RISOLVI QUESTO PROBLEMA? PER FAVORE

Translated by GT: ARE YOU SOLVING THIS PROBLEM? PLEASE
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Maybe it'll be fixed in next release.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
I broke your record lol 314k
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Ah men you broke my score i will use my extreame cooling

Score soon hehe
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
When score with sub temp cooling?😂😂
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Nah bro i cannot get sub temp but battery can touch 20°c 🤣🤣🤣
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Break through 340,000. That's the current record.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Evidence + A71 + S21 for comparison lmao

Don't blame me if Ace is God. It's about bringing that potential out. My dream is to see him eventually finishing the S8/Note8 project and getting his hands on a G960F. Now THAT would be interesting.
[Samsung Galaxy S8 & S8+ Cross Device Development] bntnja:
Wow 340k, that's super high. I only got 305k with stock settings + DVFS 95 while doing 607 hours of uptime. still this is very impressive for me. And yes, still no reboot yet. and I'm looking forward to hit the 720 hours mark (or maybe 1000 hours mark if I can lol)
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
340k :v i feel a lose when see it that so fast

I hope project a2n kernel get more device support

Today we got s8 and note 8 family exynos 8895

If can family of s9 and note 9 9810

And s10/plus 9820 and note 10/plus 9825

That will kill samsung factory developer about make kernel and improve kernel 🤣🤣 or samsung will recruit ace as kernel developer for samsung with high price
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
If Ace is willing to improve even more and learn new things, Exynos 9810's riddles will be a fine challenge for him to get through. It's a similar to the 8895, but at the same time it's a whole different beast.

Samsung is literally garbage with Stock Kernel. This one developer, Ace, is capable of beating the whole Samsung team at their own game. Unbelievable
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Next build soon (maybe in a few hous) available with DVFS max allowed 100°C + some little improvement in driver. That should probably beat 340k in Antutu.

@PORTER2002

Can you please tell us the used filesystem format of your SSD?

Also does it have more than one partition?

When you connect the SSD, what error you see? - Device is not formatted and should be formatted?
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
The last release decreases frequency switching delay to 20ms? Now THAT together with the slightly improved driver and 100C DVFS should allow 342,000-343,000+ by improving then CPU score. In theory this thing with a 2,65-2,7 OC should get well over 90,500 but throttling is the absolute limiting factor of Exynos 8895. Samsung really did it dirty with that mini heat sink.

GPU at 683 would be the best quick and easy way to get a 350,000+ but, as Ace said multiple times, for some reason Samsung decided to make it HARD to significantly overclock that thing
[Samsung Galaxy S8 & S8+ Cross Device Development] xian07:
Not the best kernel, charging is definitely an issue in this one it worked fine for a couple of days then broke (tried maxing out charging and battery temp settings, still charged slower) as well as battery life (tried the most battery saving one as well). Had 1 minimum random reboot or complete freeze per day. Switched back to another kernel and both these issues are non existent. Paid for the app on playstore as well so yeah.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Same issue as mine, max current goes not above 400 or 500 after charging bugging out?
[Samsung Galaxy S8 & S8+ Cross Device Development] xian07:
Yes tried changing the settings as well as different chargers, it was definitely the kernel because I switched back now and its normal fast charging.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@xian07

Kernel default is fast charging only in LPM mode, no matter if you have the full version or not. Also even if you have the full version, it still doesn't activate fast charging. You need to increase charging current.

Also after you reboot the phone, you need to start the app and pass license check, then you higher charging settings will be applied and used. You can check actual charging current in the app itself.

As for instability issue, please check post #3 how to properly report such issues. I believe that it really happened for you, but without logs it's quite useless to report bugs.

Anyway, I'm already aware that this kernel is not 100% stable. Next build will be 100% stable. If you have any questions, feel free to ask here.

Also it should be noted that you need latest kernel and app version to make settings apply. If you use latest app with older kernel build it won't apply any setting. Same viceversa, you can't use old app with latest kernel, for security reasons and QoS. (quality of service)
[Samsung Galaxy S8 & S8+ Cross Device Development] xian07:
Yes I figured it doesn't fast charge by default so I set all the settings to the max when I installed the first time, it worked for like a week before breaking.

I definitely appreciate the work you have done here because the Overclock definitely works and the performance increase is there, I should have tried to upload logs but didn't think of it cuz not tech savvy enough.

Just wanted to give my input to new users who have an S8 as their main phone that it isn't 100% stable yet.

Keep up the good work brother!
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
This is a very fast Kernel and it's definitely better suited for people with higher skills when it comes down to tweaking. I literally never had a single issue for roughly 556 hours without rebooting now. And several charging cycles. No random reboot, no freeze.

Admittedly, I am on Alexis ROM, which is a very stable OS.

Like any Custom Kernel, this is a hit or miss. With the difference that you're 80% going to hit and 20% going to miss. Oneself has to acknowledge what they're getting into with phone modding.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
New release is Up !!

MTP version for Android (custom ROMs) is broken - will be fixed in next build.

Well now I've also run this Antutu bench. (Latest version)

Using latest A2N kernel with Samsung ROM.

No special cooling method, but phone was on the table during the test. Yeah that way the heat can go to the table.

Also set display brightness to min to reduce heat. In addition the phone was charging only with 500 mA (Notebook USB 2.0) in order to not add any heat from charging.

First run is the one with smaller score.

Setup:

CPU/GPU DVFS 100°C

zRam 100%

CPU big 2,7 GHz

CPU lil 1,9 GHz

GPU 572 MHz

Second run I've tuned CPU/GPU up_threshold to 50%.

See attached screenshots.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Atleast im beating your score with the new kernel build😄 330k🎉

Setup:

Performance plus profile

Cpu big 2704

Cpu little 1898

Gpu 572

Zram 100%

Cpu and gpu Boost enabled

Up threshold 40%

Dvfs 100c

Swappiness 195

Page cluster default

Read ahead 512

Else what i have done, force closed all apps and turn airplane mode on and placed phone on a cold surface like a table.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I'll try to see if we can get a new record once I'm home. What makes me sad though is that my phone doesn't manage 2704MHz stable at all. Best is 2652 and I need to put it in charge for that. Peak on battery is 2574. But in daily usage I run at 1703. Great battery life
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I got 90k at cpu but i will test again later

And dev i got problem when open camera that took longtime to open it
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
hi dev how to change resolution ?

i tried but not work
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Did you tried both to execute cmds one time with cable connected and one time without having the cable connected?

Try also to change resolution from the phone, 3 different ones.

You have to test all combinations, as I said I don't have the required equipment to test it. Good luck.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
yes it works dev THX BIG THANKSSSSS
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I'm glad it works. But you may write a little how-to for others having the same problem. I'll add in post #3.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
STEP BY STEP change resolution mirroring using HDMI

1. open init.d editor (i using hktweak)

2. then write this code

cd /sys/class/dp_sec

echo 16 > forced_resolution

3. and voila resolution will change

Edit:

Try it when you plug HDMI cable to your phone that will diconnect and reconnect to get right resolution
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Well if that worked then you can force any other resolution as well.

Maybe i'll add it in A2N app.

Note: on kernel installation init.d scripts will be always wiped. So i suggest to move your fail-safe scripts to /system/etc/init.d.a2n.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
@ace2nutzer i found i guess a issue, i watch sometimes twitch in pip mode and sometimes something closes pip mode randomly and it doesnt work in pip mode anymore till i do reboot. Idk if it is a rom issue or app issue or caused by mem management. Idk if you know suggestions what it fixes it
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I don't think it's kernel issue.
[Samsung Galaxy S8 & S8+ Cross Device Development] bntnja:
656 hours so far and still no reboot for me. Now I'm on the new version, let's see how many hours can it go.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Same for me, works perfectly now.

Finally.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
I dont have any issues since one build back, latest build also no issues so far
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
Hi Dec,

After last update I notice Bluetooth issues, devices are slow to pair or won't pair at all, could this have anything to do with kernel?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Maybe yes, but then it should be the same with previous build.

Will fix it on next build.
[Samsung Galaxy S8 & S8+ Cross Device Development] kvasimodo:
Kernel 2022.04.06, unusable on custom rom hades v12, phone keeps restarting! Better stay with the previous version, or upload another kernel and wait for an update if it is released!
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Isn't Hades Android Q based? This Kernel is for Pie. Anything above is pointless
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
No it's Android 9.

But he should post last_kmsg or i'll ignore the report.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
I checked and hades v12 is indeed android 9 based
[Samsung Galaxy S8 & S8+ Cross Device Development] leonidasZ953:
And me have Hades v12 rom and all is perfect..Try to install again maybe it fix it..
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
@ace2nutzer was patching the rom with the a2n patch zip still needed with the actual build? If yes, maybe he forgot to flash it
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
Hey brother so I rolled back to previous version and the Bluetooth problem is fixed.

What was happening for me is that once I turn bluetooth off , when I turned it back on the paired devices list was empty.

Im on S8, horizon ROM

Hope this helps

Re: continuous reboot a fellow user is experiencing, I also experienced that. For me it had to do with using unstable frequencies and too high CPU temperatures. I had to reinstall stock kernel, change frequencies to normal parameters in a2n app and then reinstall a2n kernel.

I'M ITALIAN IS STP WRITING THROUGH TRANSLATOR I AM NOT ABLE IN ENGLISH THE PHONE READS THE FAT32 AND EXFAT FORMAT THE SSD FOR NOW HAS A PARTITION WHEN I ATTACH SSD TO THE PHONE NO ERRORS EXIT DEVICE CONNECTED VIA USB BUT DOES NOT READ IT THE ADAPTER BUT THE ADAPTER DOES NOT READ IT I CONNECT IT ON THE PHONE POWERING SSD WITH THE PHONE DOES NOT READ IT IF I FEED IT SEPARATELY AND I CONNECT IT ON THE PHONE IT WORKS AS NEVER? 3 kernel updates ago everything worked fine
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Hard to understand.

I've wrote him a pm in italian language.

Btw he said it worked, but it's hard to believe because I've tested with my USB 2.0 HDD 1TB and it doesn't work too using latest kernel. It doesn't work even with Samsung kernel, so i wonder if it ever worked with this kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
No, not needed anymore. Patched added again to kernel package, since they are needed for every ROM.

I don't think so, there is no changes to BT. So it's impossible. Last BT changes are several builds back.

Sorry, please don't be offended, but it doesn't make any sense on technical side.

Nobody forces you to use DVFS 100°C, you can set to 95°C if 100°C isn't stable for your phone. A2N app apply the setting in RAM, that's why A2N app applies on every boot the settings, otherwise kernel defaults will be used.

And on stock kernel the A2N app applies just nothing.

As for random reboots, as i said many times, saying it rebooted or bootloops serves nothing without posting logs.
[Samsung Galaxy S8 & S8+ Cross Device Development] Luiz2004:
what compiler did you use.
[Samsung Galaxy S8 & S8+ Cross Device Development] spdrfx:
With the latest release the booting process takes like 2-3 minutes, its stuck at the samsung logo, but after that the rom is working. Anyone have that problem? (galaxy s8)
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
ROM ?

If you reboot, again that long booting ?
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
to rule out the possibility of being another problem, i installed latest kernel again, and my paired devices list was gone, and same problem happens: if i pair a device, and switch BT off and then on again, it is unpaired.

switch back to previous kernel and the problem isn't there anymore.

perhaps something about the interaction between my rom and a2n kernel since i'm not on stock. nevertheless, thought i should report it here to the best of my ability.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:

Hello, I think Android Auto doesn't work properly in the latest release, someone please test, I think there's some issue with BT.

In 11.03 build everything was perfect, I had very long and stable AA sessions on my trip
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
I have no issues so far with BT, my smartwatch syncs notifications etc without issues over BT. Maybe its a issues with roms based on older versions of the stockrom🤷‍♂️ also no crashes/lags etc or long startups in my case
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah it seems only some custom ROMs are affected. Anyway it seems to be related to secure folder changes in kernel that breaks BT. In case you have issues with latest build, downgrade to previous build. Both builds are unlocked and compatible with latest A2N app. Basically new test build is done that should fix all the reported issues with latest build. We are just waiting for the italian guy for more informations about the SSD issue. I hope he don't say it has NTFS filesystem, because Android doesn't support by default to mount NTFS sdcards or usb mass storages. So even the fact you have enabled NTFS support in kernel, it still doesn't mount it automatically. But it can be mounted manually (didn't try it yet, but it should work). Anyway that missing support for NTFS can be added in custom ROMs before starting ROM compilation.

Btw is MTP & PTP working correctly on custom ROMs ? If not that will be fixed as well on next build.
[Samsung Galaxy S8 & S8+ Cross Device Development] MUNISH MONGA:
I use Deluxe Rom based on DUD1 firmware, MTP works fine if I keep the MTP Android option disabled
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Or someone else here with USB SSD storage that could test if it works with latest build ? And also later with a test kernel ?

Best way is to test with EXFAT or FAT32 because NTFS is not natively supported.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Something is wrong with the memory management or something, becus i was watching something on twitch in pip mode and watching the xda threads on chrome and poof everything was killed on background including magisk root and viper4android and termux.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
I have an nvme m2 usb ssd, but cant test it becus it is in ntfs format and has important stuff on it rn so yea, formatting it is not possible rn.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
With latest build of kernel and app ?

Zram 100 % ? If so, try to tune swappiness. Try 100; 130; 160; and 190. Other than that, try with stock dalvik heap sizes.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Latest kernel and app yes.

My settings:

Zswap 100%

Swappines 150

Pagecluster 0

But i'll try with different swappiness now, btw what were the stock dalvik heap values again? Try that aswell
[Samsung Galaxy S8 & S8+ Cross Device Development] hassan44835:
I have a problem when I plugged my phone into PC I can't transfer files, just when I put it in recovery mode at twrp

Im on light rom with zram 100% i don't have any random reboot with this release 2 week + and performance is good for me
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Stock for S8/S8+/Note8:

dalvik.vm.heapstartsize=8m
dalvik.vm.heapgrowthlimit=256m
dalvik.vm.heapsize=512m
dalvik.vm.heaptargetutilization=0.75
dalvik.vm.heapminfree=2m
dalvik.vm.heapmaxfree=8m

Probably still the best config.

I didn't understand well, in TWRP MTP works but not in Windows ?
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Okay, try it with stock dalvik values now besides the targetutilization one
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:

[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
@ace2nutzer question, does the balanced a2n kernel profile or a low battery % between 15-5% cause a app autokill or is it coincedence? Becus it happend 2 times when im on balanced and having a low battery %
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Kernel doesn't do such a BS.

Therefore check your ROM settings.

Disable all battery settings.

Use power mode "optimized" and disable 'adaptive powersave".
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Alright, thats all i wanna know lol
