[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I've never tested this, but i think it should work.

Yes i'm aware of this, and coming update will fix this issues. (u'll be able to set one of 3 different zram sizes)

it's known bug, but since it works as well with the default back button, i didn't spend too much time at this... it's not important, there are actually more inportant things to fix or to improve. But when i've the time, of course i'll fix it.

As long as your Battery + Charger + Cable IS NOT DEFECTIVE, then nothing bad will happen !!

You can use any Chargers and Cables .... you can't do anything wrong. The driver and the hardware has many security things .. so not only one.

U can't overcharge or overheat... even with 3000 mA it's safe @ 9V (AFC)

Check this from the App:

That means, it'll charge with 3000 mA till batt temp is 45°C ... then it'll charge with 500 mA till batt temp is 40° or lower ... then it'll continue to charge with 3000 mA (or other value set from user of course)

All tested ... works perfectly.

More info: even the worst Li-ion battery is made to handle AT LEAST 1C charge current ...that means, at least the battery capacity ...

so on S8 it's 3000 mAh ... so it's safe to charge at 3000 mA ... this is 1C.

The only thing i didn't test is the S8+ if it can handle 3500 mA @ AFC 12 V

Since the S8+ has 3500 mAh battery, i've allowed and programmed only for the S8+ to set up to 3500 mA, (so if u've S8, your max adjustable is just 3000 mA) but the problem is i don't own an S8+ .. so i'm depended from the feedback from this Forum / thread.

According to the stock source code our hardware can handle max 12 V.. so i assume that it should work.

On the other hand, in Software, so in Android Settings--> Phone info ---> Status ... it shows: nominal voltage, nominal current: DC 9 V; 1.67 A

But i don't believe that this is the real limit. Those Values are exactly just the same like the stock AFC Charger.

If someone has an S8+ stock AFC Charger ... please post the Values for voltage and ampere.

If it has also 12 V output, then it's clear that we can charge with 3500 mA using 12 V.

Because like i said before, 9 V 1.67 A only allows us to charge up to 3000 mA.

How to calculate:

9V x 1,67A = 15,03 W

but we need to convert to 5 V ...

so, 5V x 3A = 15 W

that means the stock AFC charger for the S8 his max possible is just 3000 mA.

So to charge with more than 3000 mA, we need higher current on the 9V output or maybe better 12 V.

So if someone want to charge S8+ @ 3500 mA isn't problematic, then only thing than can happen is that it gets broken with 12 V Charger .. .because i've never tested this !!
[Samsung Galaxy S8 & S8+ Cross Device Development] khanhbang2013:
I see the 18th version, the battery is better than the 24th version, I feel the 24th version uses hotter faster, and the battery drops faster, because I tested carefully when I said this,
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah, likely due to the HMP Driver, but 18th has heating up issue sometimes.. so high battery draining ... but as i said i've re-implemented HMP driver now .. and fortunately heating up issue is gone. :fingers-crossed:

I'm so sorry for the delay for the Update, because actually i'm (again! :mad:) in trouble with Google, as some of u may realized that my both Apps (Ace 2 and S8) where removed from Google Play. Now i'm waiting for their response within 2 business days. Then i can finally upload new Kernel + App.

But fortunately the current Full Version App still continues to work properly for the users that have the license .... fortunately !!
[Samsung Galaxy S8 & S8+ Cross Device Development] khanhbang2013:
and I find that the 24 Ram version is lower than the 18 version, the 18 Ram version always has an average of 1.6gb free!!
[Samsung Galaxy S8 & S8+ Cross Device Development] hubix:
I have a problem with Full version of your APK. On previous ROM it was available to download from Play Store, on current one (Alexis ROM) it's not in Play Store anymore. Can your help me resolve that?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
A2N Kernel Control Full Version

As a temp Solution for users that have already the license ... ;)
[Samsung Galaxy S8 & S8+ Cross Device Development] monoik:
This is the same version that was on the store, right?

When can we expect the updated kernel?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
yes .. + optimized Performance profiles for reducing device heating.

When the App is unlocked in Play Store.

in 2 - 4 Business days
[Samsung Galaxy S8 & S8+ Cross Device Development] xbmc79:
Is there any way to adjust the cpu and gpu voltages like the s6 and s7?

The performance boost where awesome on the s6 with synapse and the aldeon kernel.....
[Samsung Galaxy S8 & S8+ Cross Device Development] artur_spetsnaz:
Good work, good kernel! I'm not sure but with this kernel Google camera's HDR+ processing is slower than on stock and even lags while capturing a photo. btw battery life is great.
[Samsung Galaxy S8 & S8+ Cross Device Development] sandert98:
Really looking forward to the new update. I hope Google will publish it fast :)

I like the better battery life, but performance overall is not good.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Please search the Thread before posting. No, S8 has Voltage auto-calibration.

@ ALL

So actually we've better battery life, more smooth but worse performance ? Well, let me see if coming Update will improve Performance. :fingers-crossed:

It's shortly online, as well Full Version. :cowboy:
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
communication : WA, Tele, Discord

Socmed : IG, FB, Twit

Forum : Kaskus, XDA, reddit

the highest usage is WA and tele with 1-2 hrs SOT usage each in average, next highest usage would be mario kart tour and or mangazone hahaha.. autosync is off for emails (imho this is the real battery killer).

if i put the performance mode on then i'll be out of juice at 2-3 PM most days, that's why i use balanced mode most of the time to squeeze moar juice thru till the end of the day..
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
hmmm almost same like me bu no with twitter i don't have it hahah for autosync hmmm better to try hehe thx bro

i was never tought when press it that close background apps hahaha okey dev
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah, but sometimes there are closed apps that still cause CPU load in background for no reason. I've faced this many times, because I've app that shows me current CPU Freq, there I check sometimes if CPU IDLE works properly.
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
Random reboots after last update...
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
According to the log, big CPU failed. Try to increase big CPU voltages.

If you don't know how much to increase, +25 mV is a good starting point.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
same here i use crack devcheck :v to monitor and usage is like 100ma lowest and open an app what ever the app can jump to 1.2A

and dev i think this new build have bad battery life for me may need figure out the setting but i have been do ultra low voltage each freq
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
New kernel/app default is now: swappiness 160 (prev. version 190)

zRam 50% (prev. 100%)

And re-added PM-QOS for audio like on stock kernel: big CPU 1170 MHz (prev 741 MHz)

Those are the settings that could make some difference.

Try to use old settings, but on the other hand you may revert bug fixes for audio for HD playback and HD calling.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
hmm okeyy i see

i get to default again like before update and i saw something weird in my battery voltage it is normal ? when unplug it voltage drop to 4v
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes it's normal if your battery is really old, drops from 4,4 V -> 4,0 V.

If it's new, it drops only by 0,5 V - max 0,7 V.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
wait what more bad then old battery ?i figure out some thing i can get no drop when charge it slowly from 95%
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
?

It depends on how much CPU load is there after you unplug the cable.

High CPU load = will drop more on old batteries. This is how it works an there is unfortunately no software tweaks for dying batteries.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:

Compatible with hades rom android 10?
[Samsung Galaxy S8 & S8+ Cross Device Development] Just_try:
Excuseme sir,i'm recently flash kernel with date 11 october.

I have question, If i flash the updated kernel should i factory reset again?

Thanks Mr Ace
[Samsung Galaxy S8 & S8+ Cross Device Development] junior19694:
does it work on roms with android 10?
[Samsung Galaxy S8 & S8+ Cross Device Development] Ferrumlan:
It's only for stock samsung android 9 ROMs. But you can test it with stock like roms. Don't forget only android 9.
[Samsung Galaxy S8 & S8+ Cross Device Development] oleg vegas:
I have one question, will there be at least one core release for aosp? And perhaps you know how to regulate the temperature of trolling on a large processor, again on the AOSP firmware?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
No, just flash new a2n kernel and then magisk. That's it !

No, sorry.

You can't, because it's hardcoded in kernel. The only thing you can do is to use lower big CPU freq. For instance use 2GHz and then you can safely disable throttling without to cause reboots by overheating.

To disable throttling run this cmd as root:

stop thermalservice
[Samsung Galaxy S8 & S8+ Cross Device Development] Just_try:
Thanks Mr.Ace
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
Previous version of the app allowed the maximum temperature of 45 degrees for CPU and that was super useful to me since my phone was already serviced and heats up a lot. Can you bring that back ?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Nope, new algorithm doesn't allow this because there is a margin of 10°C to allow Freq to raise up. With 45°C CPU Freq would stuck at min_freq for ever. Also that heating up issue is coming from HMP driver. Going to fix that.

Hotfix shortly online.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
45°C CPU max even after the mod I've done would literally lock the CPU down to like 1GHz. **** performance right there
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
That stop thermalservice things seems so tempting...but I don't want to cook my phone :ROFLMAO::ROFLMAO:
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
That was only meant for non-a2n-kernels.

On this kernel thermalservice is disabled since we use our own DVFS kernel thread.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Right. I forgot about the fact you're the only gigachad developer who ditched all of Samsung's work and redid it yourself from scratch WILLINGLY :LOL:

This is @ace2nutzer irl y'all
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
no just android 9 compatible
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
for real gigachad bro 🤣🤣🤣

and bro i have little job to do when you bored hahah

rush samsung community with info samsung s8 family rise up the plan is make a thread on there how good dev make kernel for it i hope he get promoted to samsung developer 😁😁😁
[Samsung Galaxy S8 & S8+ Cross Device Development] Just_try:
what happen if i downgrade the kernel with version date 11 october ?

now im using kernel with version date 14 october
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Should work fine. But older versions not.
[Samsung Galaxy S8 & S8+ Cross Device Development] Just_try:
Thanks for reply sir
[Samsung Galaxy S8 & S8+ Cross Device Development] denyo81:
Does the kernel work with LineageOS 20?
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
if android 9 yes
[Samsung Galaxy S8 & S8+ Cross Device Development] denyo81:
No that's android 13
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
It doesnt work on android 10 and higher
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
is this R53? not pretty sure since there's no other version signs

edit: anyway i flashed it and boots fine
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes latest version is now R53.

Changed from date to Rxx. Kernel & app will have now most of the time the same release version. Just to make things more easier. Next release will be R54 and so on, but zip file name will be always the same.

Anyway, you see current release version in thread title + in "latest" file in FTP server. In addition you see the kernel release in settings software info .. kernel version shows you the flashed Rxx version.

I still am king of the hill 🍺🍺🍺🤓😆

In some days I will start running benchmarks on the S8. Since I didn’t run any ever since I repasted it because life is busy. Hopefully I’ll get a bit better scores
[Samsung Galaxy S8 & S8+ Cross Device Development] Adbnpk2013:
hy @ace2nutzer , as i mentioned that my phone has known problems of severe battery drain and not turning on when I turn it off until I connect charging cable. i was wondering, if there is a way to manually turn off all other functions of type-c ports except charging?, or if I can even turn off the whole charging port and use wireless only?. i think there is some problem with the charging port which I cant figure out. perhaps its worth a try to manually turn off one by one functionalties of the charging port if maybe I could figure out whats causing it.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Did you try if you can turn it on with a USB-jig ?

Anyway, check this page, there are schematics and service manual for the S8. (4 PDF)
[Samsung Galaxy S8 & S8+ Cross Device Development] Adbnpk2013:
yes usb-jig and when connected to charger, the phone will turn on normally. however, I have made peace with not turning on issue, I can mange that. the problem that bothers me the most is battery drain. the drain is around 10 to 15 percent per hour when screen is off. its not background apps or other wadelocks etc that is causing the issue, its specifically due to the charging port somehow. but again the charging port is good as I have changed it recently along with charging i.c , I think the problem is somewhere in the connector that connects the charging port to the main bord. As the whole point is to make the phone somewhat workable without changing the mainboard. therefore I am trying trial and error method to find out the culprit. one of the idea is to shut down functionality of the charging port if it can help.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@Adbnpk2013

Hmm yes maybe it helps to remove the port, but it's really bad idea. Because you'll loose ADB access and ability to flash ROMS with ODIN.

The only way to fix that, is to follow the repair manual. (taken from the link I'd sent you, it's from the first PDF) See in attachments.
[Samsung Galaxy S8 & S8+ Cross Device Development] Adbnpk2013:
thank you, i have been consulting the schematics for a while now. do you know the required voltage and amps for initial boot of s8+ ? i mean if I don't connect the battery how much voltage and amp should I provide from the external power supply to boot the phone ?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@ up

Nope, you can't disable USB-charging in kernel. It's hardware issue, just fix it.

Min required bat volt = 3,5

To boot the phone without battery, you need 3,8 V with stable 3,5 A.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
use multimeter add some resistor to know it
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
yups this is right but it must connected direct from socket because just with usb the phone just initialize only 5v unknow A
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
i think you better check battery and check charger flexibel that no too expensive try with phone service maybe can fixed if fixed you can pay them
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Current setup😂 more phones and stuff to add to the list and my s21 is not using all the cores yet😆 @rtyuakatsuki
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Whats that ?
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
flashed R54 and updated the app, boots up 2 seconds faster than it usually does..
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah thanks for remind me, I'd forgot to write it in changelog.

Basically increased CPU boot max temp from 65 @ 75°C.

wipe dalvik-cache should be faster as well now.

Mining setup currently, not the fastest one but better than nothing
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Is it really worth it compared to the high cost of energy ?

How much profit you make monthly with mining ?
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Well, the devices are old laptops and phones so it is cheaper than using desktops or asics. Anyway with the current setup its not super worth it with +- 1.24 dollar a month. But i could still add maybe 5 phones + 2 desktops + 2 laptops
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
uh man hahaha
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
add more devices get 2 atlest 3 mh/s if touch more the 14 mh/s you can make 5.8 dollar a month
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
i think you can wait it for while that will increase to 4 or 5

Question, u know the s6 920f has cooling issues becus bad cooling? Becus mine is getting incredible hot. Not even using the stock max frequency of both cpu clusters.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
i think the stock voltage is get overvoltage like me

in my s8+ i get overvoltage far from dev have too far
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Potianally i can use my s4 too but not sure becus theres no rom on it rn. But the phones like the samsung advance and before i've tested and are too slow for mining. So depends on current setup and my s4 and my 2 desktops and 2 laptops i didnt use yet. Keep it posted
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Maybe its just broken becus i smashed my s6 on a table when i got mad back than on school😂 anyways disabling temperature control in the miner app and it mines now.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Share the detailed results. You made it to the top by far. Now I want to study your result :cowboy:

Incredible that with excellent cooling, 8895 can become as good as the average 9810, just as I predicted, and with 839MHz GPU and 2.8 CPU it's even more interesting. On its own doesn't really sound great to those well acquainted with the 9810, but think about it. You reach next gen level of performance without even spending a cent (well, an euro, for the a2n kernel manager, still like,1000x more worth it than getting a new phone). Ace did magnificently. With RAM OC, hopefully, if he manages, we get even more free performance. A miracle, really.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
He got better score than Note9 with S8 Plus. :cool:

@TechNoobForSale

With stock cooling system you get better scores with 2,7 GHz. But with water cooling 2,8 GHz is better.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Dude remember I’m on G950F. My cooling can barely handle 2.6 (2574) lmfao. I mean, now I still need to test after thermal paste. Maybe it improved to 2.65. But I hardly see it managing 2.7 in benchmarks reliably.
[Samsung Galaxy S8 & S8+ Cross Device Development] Joker6126:
I've been having trouble resetting constantly in the last few versions. It's nice if they don't.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Do you use the latest version R54?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
If you use higher Freqs than stock (2314, 1690, 572), then first of all: you don't need to report bugs, second: you need to adjust voltages. Try step by step which Freq is unstable and increase voltage.

Otherwise please read post #3 how to properly report bugs with logs.
[Samsung Galaxy S8 & S8+ Cross Device Development] Joker6126:
Yes
[Samsung Galaxy S8 & S8+ Cross Device Development] Joker6126:
