[KERNEL][4.4.194+][for Android 9] A2N Kernel for Galaxy S8 / S8 Plus / Note8 Exynos [R57]
- Thread starter ace2nutzer
- Start date
I’d put Noctua thermal paste on it but I have no idea how to open that thingokey
I can’t comprehend what is going on in that image lmao
the image is the mainboard bro the s8 plus :v maybe the s8 have little diffrent shape but still same
I know the structure of the main board. I just don’t know how to open the phone itself dude
I opened it and I see where the SoC is. There is a thermal pad on top of it. What do I do now @rtyuakatsuki
What ? Charging voltage 4,4 ?! In source code it's everywhere 4,35 V.
Also 4,35 V was for old phones like the Ace 2. Now I wonder if S8+ and Note8 has also 4,4 V spec. If so then I can update charger control to 4,4 V having more battery. That could increase battery life to 5 - 10%.

replace it with copper plate that best option i measure the thickness is 2.5 mm or 2mm better take 2.5 mm and use sandpaper if too much
Yea, phone cooling is rlly a joke lol

Yes² btw for gaming this phone kinda beast i ve tried 839 mhz as well it run carxstreet well fps get 35 to 40 mid to high1
Lowest :v i dont know the exact resolution
But i set it to low
But for all high its get about 30 to 25 sometime 35
839mhz i only can use it if the load not 100% if that touch 100% it will consume all the power and make crack sound even use charger -

You can use now latest Magisk version without any issues!4Right, R56/R57 is already 4.4.194, as I just forgot to update Makefile Linux version. But as I said before, it's not a full clean upgrade, it's only for memory management and since it's the most important part for performance and security, I'd just decide to call this as an upgrade.
R58 already in the kitchen and will have mm upgraded to 4.4.302 and maybe zRam upgrade if needed, after that, this kernel should work extremely well.4New Release is Up
Changelog
A2N Kernel R57 (Hotfix)
- Fixed low FPS in games
- Improved RAM
- Improved DVFS for CPU/GPU
- Added gaming mode
- CPU: allow input booster up to 5000 ms
- GPU: added gaming mode

Sure I'm working on new build, but it'll be still only for Android 9.
It'll have big improvements in performance and it'll be upstreamed to latest Linux 4.4.302.2On your repo:
Revert the 4.4.302 commit:
Because it's not buildable for now since it needs a commit that should fix all build errors, didn't had time to do it, but I'd still push it to git as an backup, since my HDD is quite old now.Code:git revert 925ecbb256198d515a3b06e6fb5787d0cf216d89
As for the moro sound:
Are you really sure that you did it right? The original commit has more changed files and much more changed lines of code. So I don't think that it'll work or compile at all.
One last thing:
while it's ok to cherry-pick commits from other developers, you always should need to keep the credits to the original autor. You can still use the "patch -p 1 -i 0.patch -r rejects" method, but when you commit, add at least the original autor or git link to the commit.
Another also nice way ist to generate a *.patch patch, instead a *.diff patch.
Then it'll write proper commit message with the original autor. (Like nox did)
To apply such patch, the cmd is even more easier:
If no conflicts, it'll add and commit the patch. Otherwise follow the error message to see how to fix the source files... then use "git add ." And then "git am --continue" or something like that, I don't know exactly right now as I'm only on the phone online right now. Anyway you will see the exact cmds on your terminal emulator, so don't worry.Code:git am 0.patch
Note:
Sometimes when you add patches, it'll also add new files. Those new files are untracked, so even if you commit with the "-am' option, it'll still not add the new files. To fix it, before you commit the patch, use "git add .". -

17FAQ
Q: With which ROMs this Kernel is 100 % Compatible ?
A: Currently only with Android 9 custom ROMs, but Samsung stock ROM is recommended.
Q: Is this Kernel 100 % Safe ?
A: Yes.
Q: Will this Kernel Overheat the Phone if I use Highest Settings ?
A: No, you can't do anything wrong. Your phone has hard- and software overheat protection.
Q: How to Revert all Changes Made by this Kernel ?
A: Flash latest 3-parted stock ROM with ODIN or flash the Samsung kernel from my download site.
Q: How to bypass SafetyNet ?
A: Anable MagiskHide in Magisk app.
Q: How i can Tune this Kernel ??
A: Everytime you install or update this kernel you will face an red (demo) app "A2N Kernel Control..." open this app, and it'll redirect you to Google Play to get the full version (blue app).
Q: Can i use and Tune your Kernel with other Kernel Manager Apps ?
A: Yes, but you need first to unlock kernel with the A2N app full version.
Q: I've Installed the Full Version of the App, Will it Change any Kernel Settings by Default if i do not Change them ?
A: No, default app settings = default kernel settings.
Q: I've the Full Version of the A2N Kernel Control App, Do i still need the Demo Version of the App ?
A: Yes, there are some special features in-app-menu like "Fake Enforce" and debugging features for easy bug reports.
Q: How to Charge from 10 % to 100 % In just 1 h ?
A: E.g. set "AC Current Max" and "Maximum Charging Temperature" to the Max.
Q: How to get Max Speed for e.g. Highest FPS in Games ?
A: Set BIG / LITTLE CPU and GPU Freq to the Max, but avoid to use "unsafe" Freq's.
Then set CPU / GPU --> DVFS --> "Maximum Temperature" to the Max.
Now you can even cook an egg on your phone !
Q: Will my Custom A2N Settings Survive if i install Stock Kernel and then going back to A2N Kernel ?
A: Yes, as long as you don't uninstall it.
Q: Can i use your Kernel Control App with other Custom Kernels ?
A: No, it's not universal kernel manager app.
Q: My A2N App is Crashing after an Update, how to fix it ?
A: Re-install it. If it doesn't help, wipe dalvik-cache in recovery.
Q: My A2N App shows: "Please check your internet connection" - But i've good internet connection. - How to fix it ?
A: Settings --> network settings --> use private DNS server like "dns.adguard.com" - confirmed to work by user @Arnz09 - see his post here.
Otherwise send me a pm with the screenshot and you current location (city)
Q: Why I get lower benchmark scores with this kernel compared with the Samsung kernel ?
A: This kernel uses by default Max CPU/GPU DVFS Temp 65 °C to reduce the device heat. You can buy the full version of the A2N app to set the DVFS Temp up to 100 °C to get higher scores than on stock kernel.
Q: Why the Android Battery setting "fast charging" has no effect on this kernel ? - It charges always with around 1500 mA.
A: Because it would conflict with the built-in charger control.
The default charging current of approx. 1500 mA means no fast charging by default, even if you actually see "fast charging" in the notification section. This is also useful to reduce battery stress and device heat. To charge even with higher speed/current than on stock kernel you need to buy the full version of the A2N app.
Q: Why I've to pay money for just changing kernel settings ?
A: Well quality has its price. Also nobody forces you to use this kernel.
You can flash other custom kernels or flash the Samsung stock kernel from my download site. Good luck !
Q: When we get an update ?
A: This kernel is almost 100 % stable and works very well. Also this phone is now a bit "old" and therefore don't expect frequent updates.
Also don't ask for ETA's and if you do anyway, I'll ignore.
Q: How to fix audio stutering ?
A: Increase the UHQ PM-QOS-LIT Freq in A2N app in "Audio" section.
If you don't have the full version, you can run a cmd like this:
Q: What is the benefit of editing the voltage table ?
A: to increase OC stability increase voltage and to decrease the device heat, decrease voltage. Last one will improve performance due to less throttling ! So it depends on your needs.
Q: How much is safe to undervolt ?
A: approx -50 or -75 mV is considered to be "safe".
Q: How to edit voltage table ?
A: First of all: to set different CPU/GPU clocks or voltages you need to have Magisk installed and buy my A2N kernel control app full version. This will unlock all premium features of this kernel.
To edit GPU voltages for steps > 572 MHz ---> use the A2N app full version.
To change all the other voltages, you need to use ADB and later once you have found the proper voltages for your phone then you can write them to a script that will be executed at every boot.
Note: this voltage table is from my phone. Your phone may have a different table, so please use your table when it comes to calculate how much you want to undervolt. (50 - 75 mV or 50000 - 75000 uV should be safe)
I'll help you, here we go !
Q: How to Report Bugs ?
- Please DO NOT report bugs if you are:
--- using "unsafe" Freqs
--- not using the latest release !
--- not using Samsung stock ROM (based stock ROMs are custom ROMs !)
A: Open the red A2N Kernel Control demo app and check in-app-menu (3 dots) then "Debug" and then on "logcat and dmesg" if you faced an app crash or if some features didn't work.
If the phone rebooted randomly, then tap on "last_kmsg". You will find the logs in your internal storage. After that you can attach them here in your bug report, by clicking "Attach files".
