Alright @ace2nutzer
Me and @rtyuakatsuki using devbase
And @Driieel use eclipse rom, all of them are samsung stock rom based, so i guess the screemcam app has issues on this rom somehow, but guess it is fixable with a modification or something.🤷‍♂️

I have use screencam tho but the error make timeline is broken and to fix it make separate sound from device

Yea, it only happens with recording with module and with just normal/mic/no audio it just decodes & saves fine, so theres something with decoding & saving the file when audio over module is used. Kinda weird

Yup maybe the module is have bug and need fixed for now i have no time i have much spend time for school and find some money to continue make a little project for s8 plus and other stuff

    Hmm strange. Later i'll check the GPU governor, maybe it can't handle those higher steps. On the other hand it's known that a GPU that is actually not running fully stable due to too high freq or too low power will cause such bad performance. You may can face even some graphical glitches.

    Yeah because I've increased voltage for the highest CPU steps, same for the big core. What you say is right about cold battery --> less power.
    But you can bypass this with charger cable, just use any powerful charger like the original one and enable battery idle. This will give to the phone 3 Ampere constant. You even don't need to set charging current @ max possible because the driver do this automatically now on latest release.
    Another weird thing is that I didn't manage to run 2,8 GHz stable. Original voltage for me was 1,2 V and even with 1,4 or 1,5 V it didn't run stable. Now you will be probably surprised once again, what we actually did was to unlock voltage regulator and ability to increase max allowed voltage for each regulator.
    E.g. original GPU max allowed voltage was 850 mV and I've set it @ 1000 mV and after several test it seems that the voltage above 850 mV is accepted since I can track higher GPU temp.
    So this works. Then later just because 2,8 GHz never worked stable even with insane OV (overvolting) DVFS 95 °C instead of 100 °C to be sure that it doesn't crash due to overheating... I was reading some documentation in source code about the regulators and found out that there is even the ability to throttle the max current (uA) from the regulator. But I didn't pay much attention because it doesn't seem to be used in our source code. But it's supported, that means if I specify a max allowed current then maybe that will be used lets say instead to used a max default current hardcoded in the hardware itself. Maybe I try this hack next time. If that will not work, then it's just hardware limitation that it can't provide enough power. If so, you should be able to reach higher Freqs when OC only CPU or GPU !

    It was 100% not due GPU instability but due to lower power from battery. There were 0 graphical glitches. No blackscreens. Nothing. Just stuttering, temp was low and GPU usage kept going from 0 to 40 then 99 then back to 0. It's definitely a battery problem. I will go at it like I did in the past, and keep the charging cable in.

    Also about 2808MHz not being stable, well, it really is a dilemma. For me trying to run at that frequency means getting an awful instant crash (really awful).

    I can 100% confirm that CPU big at 2574MHz and GPU at 839MHz can work together just fine. Maybe not 2704MHz CPU but 2574MHz for sure. I think that at 2808MHz the SoC is pushed to the limit and since most of us have average ASV values, it's really unlikely that we ever run it stable, even at a crazy voltage like 1.5V.

    But again, if this can be of any help, I doubt 2808MHz would even be useful at all. 2704MHz already overheats like an FX 9590 on an air cooler, let alone 2808MHz. You would quite literally keep throttling even while scrolling home screen pages.

    Now, I think that by now I know you pretty well, and you VERY hardly stop in front of a wall. But I'm telling you, it isn't THAT worth it.

    Now if in a week you come and state that you made 2808MHz stable, well, I wouldn't be surprised. It's Ace2Nutzer after all.

    Right now I recommend you try to get the RAM OC in. You peaked. You did it. You took an average S8 and extracted out of it 99,9% of all it will ever be able to give to an user. I don't think there is much to optimize left, or instabilities to fix anymore. It's complete. A2N Kernel for Galaxy S8/S8+/Note8 is complete to my eyes. From now on it's just tweaking if there is any tiny tiny issue here and there. But the bulk and the details are done. You did it (y)

    I tested in gaming too today, specifically ARK: Survival Evolved and Genshin Impact. At stock frequencies and at 2496MHz big cores and 683MHz GPU. I didn't see throttling, at all. So yeah. Best user experience Kernel, best battery Kernel (NOT debatable), best gaming Kernel, best productivity Kernel. What else is left? Lmao

    AnTuTu V7 seems to hate GPU frequencies above 683MHz or the GPU driver acts up for some reason. Second GPU test stutters and I went from 730mV to 770mV. Testing right now on 770mV. If it still stutters, I'll ditch that benchmark lmao.

    It doesn't crash. It stutters. Badly.

    Ace, it's impossible. I can't buy the app from the Play Store :/ . My aunt doesn't know how to do it and no matter how I try to explain her the procedure, she only gets more and more confused. Is there an alternative way in which I can pay you and get the app?

    Wow, I love Undervolting!
    I just put some random numbers from lowest to almost-highest freq (0.6v to 0.9v) on both CPUs and GPU and so far it's working great! The CPU is much cooler than before (-10c)
    btw, my top table of the ram is 2.09GHz, not 1.79GHz so which one should I undervolt ? from lowest to 1.79 or lowest to highest 2.09 thank you
    Click to expand...
    Click to collapse
    It's pointless to undervolt anything above 1794MHz on RAM. Higher frequency steps aren't used yet, according to Ace. So from lowest to 1.79.

    hello dev, personally I could run benchmark with full overclock (2000 mhz small cpu and 2800 mhz large cpu) in one of the previous versions, in fact I could run many benchmarks and had no temperature problem. Now after updating the kernel, every time I run geekbench, the phone always reboots.

    Yes, send me your e.mail address.
    Send me e.mail, you get my e.mail from Google Play, check developer contact info.
    Note this offer is totally limited to avoid abuse.

    Nice indeed. As for lower CPU speeds, hmm not really.. but changed some defaults. Yeah A2N app requires an update, but for now I'm waiting if GPU OC is stable enough for everybody.
    In A2N v. 4.8 you can set the following settings to get latest optimized kernel defaults:

    page-cluster = 3
    read_ahead_kb = 512
    Input booster = 500 ms.

    Other than that, updated performance plus profile defaults ... in A2N app v. 4.9.

    Btw I'm planning to reduce CPU / GPU Freq steps in order to increase performance and reducing lags caused by too excessive Freq switching. Can't say how much it'll improve benchmark scores but it should run noticeable smoother then.
    Click to expand...
    Click to collapse
    You want me to be honest? Your frequency scaling driver is already extremely fast and I hardly ever noticed lags. So even if the CPU is at 741MHz, it will go up to 2314 immediately if needed. It's really a non issue. That's a problem stock Samsung driver has, which sucks badly. But if you want to make it even better, be my guest lmao.

    What's next in the roadmap? Little cores OC? MIF OC? I think that the Kernel is nearing 100% stability. which is your objective, you said. But this thing is at 98% out of 100% of its full capabilities already. You carried the whole S8 Kernel development lmao.

    FAQ

    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: 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 !
    Code: 
    adb shell
su
cd /sys/power
# print dvfs table so we can see current votlage table !
echo 1 > print_dvfs_table

# you can undervolt every single step, so lets undervolt 455 MHz step as well @ 650 mV:

echo "455000 650000" > gpu_volt

# now maybe you want even to undervolt RAM.
# we need to go again to /sys/power ...

cd /sys/power
# take a look at the dvfs table, the very first entry "dvfs_mif - id : 0"
this is RAM freq - volt table and our max_freq is 1794 MHz.
# we will undervolt Freq step 1794 MHz @ 700 mV:
# the format string is here: "id rate volt" (intent KHz uV)
# this sysfs interface is universal and you can undervolt any voltage table you want by using the corresponding "id":

echo "0 1794000 700000" > update_dvfs_table
# and verify:
echo 1 > print_dvfs_table
dmesg
# id 4 would be for GPU (dvfs_g3d) and so on ...
# to run all the cmds for undervolting at boot, just do something like this:

# open the script /system/etc/init.d.a2n/a2n_user and copy paste your cmds:

cd /sys/power
echo "2314000 900000" > cpu_big_volt
echo "1690000 950000" > cpu_lit_volt
echo "0 1794000 700000" > update_dvfs_table
cd /sys/kernel/gpu
echo "546000 650000" > gpu_volt
echo "455000 650000" > gpu_volt

# under the line: "# A2N init.d Script"
# save and enjoy !

    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".

    ROM:
    Kernel version:
    A2N app version:
    BUG:
    How to reproduce:
    Same bug with stock kernel ? :     YES / NO

    Download stock kernel for bug reference: S8 / S8+ / Note8

    BUG REPORTS THAT DO NOT FOLLOW THESE RULES WILL BE IGNORED !!!

    • Ramdisk DSI1
    • Compiled with the OFFICIAL ARM/Linaro GCC 8.3
    • Optimized Memory Managent
    • Improved Performance
    • Improved Battery Life
    • Reduced Device heat
    • More Responsive
    • Fixed Laggs (especially for some 2D Games)
    • Increased Efficiency
    • RAM: 3485 @ 3711 MB
    • Unlocked higher CPU/GPU Freq Steps - Thanks @Noxxxious
    • SELinux in permissive mode - Thanks @Noxxxious
    • Disabled SSWAP
    • Added zRam Support with fast LZ4 Compressor
    • Added KSM Support - patched for Android by me
    • Optimized Input Booster
    • Fixed very bad CPU IDLE
    • CPU: Interactive @ conservative gov - for higher efficiency
    • Added Wireguard Support
    • CPU: Cluster 0: Screen ON min_freq 455 @ 715 MHz to Fix Lags - 455 MHz Step is used for Screen OFF
    • Compiled with DEFAULT_USE_ENERGY_AWARE / WQ_POWER_EFFICIENT_DEFAULT - for better Battery Lifetime
    • Optimized Crypto, NEON SIMD Hardware Acceleration (e.g. faster device encryption due of hardware acceleration)
    • Disabled HMP since it serves nothing - Hardware doesn't allow to use real cpu_hotplugging ...
    • Added Charger Control 2.0 by me - Allows to configure custom max input current from 100 - 3000 mA in 100 mA Steps separately for AC / USB 2.0 / USB 3.0 / Wireless - that means real Fast Charging even with Screen ON - Allows even to charge at max current possible with 3rd-party Chargers !!
    • Added Flashlight Torch Control - You can adjust Brightness of your Torch from 1 - 15 - Default/Stock Kernel is just 5 :p
    • SELinux: Removed Audit dependency - Thanks @ kerneltoast && arter97
    • Added Support for F2FS
    • Accurate remaining time to full charged battery
    • init.d Support
    • And many more Kernel Tweaks - i can't list them all here ... changelog is already too long isn't it ?! :laugh:

    A2N Kernel Control V1.4

    • The best Way to manage this Kernel for full functionality (3rd-party Kernel Manager Apps will not work properly with this Kernel)
    • Compiled with API 28 Android 9 Pie
    • Power: Charger Control - Allows to configure custom max input current from 100 - 3000 mA in 100 mA Steps separately for AC / USB 2.0 / USB 3.0 / Wireless - that means real Fast Charging even with Screen ON - Allows even to charge at max current possible with 3rd-party Chargers !!
    • Added switch for "Adaptive Fast Charging" so u can directly toggle AFC in the App.
    • Ability to check actual accepted charging current and Input Voltage
    • CPU: OC Control: Cluster 0: up to 2002 MHz and Cluster 1: up to 2808 MHz
    • CPU Governor tuning: Adjust up_threshold to balance between Battery Lifetime and Performance separately for each Cluster
    • GPU: OC Control up to 839 MHz
    • Hardcoded Performance Profiles:
    • --> Powersave (Underclocked)
    • --> Balanced (Kernel Default)
    • --> Performance (Overclocked)
    • Misc: switch for zRam, KSM
    • Misc: Torch Brightness Control - up to 3 times brighter flashlight than with a stock Kernel !!
    • Misc: Ability to load kernel Module for CIFS and NFS with just one Tap
    • Misc: Accelerometer Calibration
    • Debug: u can call this Menu over the App built-in Menu (3 dot) - ability to save logcat and dmesg with one tap to your sdcard ..

    If u've any Questions, feel free to ask here.

    Enjoy your new A2N Kernel ! :)
