Sorry for the noob question, but i am a bit new with these things.

So, i own a SM-N910G model with CSC code INU, hard_rock83 update 6 ROM and Ram RC3 kernel. I would like to change my CSC code to CNX or COA which is for my country and where i live now, Romania.

Is this possible?
[Galaxy Note 4 Original Android Development] xdauserr:
RC3

I'm using RC3 and phone doesn't wake up sometimes.

I've tested hybrid and userspace power suspend mode with bad results.

LCDpanel method gave good results, but I have a doubt about it's good power efficency.

Should I flash a stable kernel or stuck with LCDpanel?
[Galaxy Note 4 Original Android Development] Tesla:
Thanks m8.

If you have time for a new kernel besides Note 4 i would suggest Note 3/N9005. :good:
[Galaxy Note 4 Original Android Development] xdauserr:
Testing Hybrid sleep mode.

A half of an hour after boot my n910f stopped responding power or home buttons.

In such state it reboots only after power+volDown long press.

RamKernel RC4

Major changelog is DT2W is added, for other I will update this post

https://www.androidfilehost.com/?w=files&flid=189691

I recommend using stock settings only, dont change anything like gov, voltage, the stock settings will give max performance

The kernel zip clears data, cache of previous RamKernel installation, so just flash new RamKernel

Enjoy....

[Galaxy Note 4 Original Android Development] xdauserr:
To achive better screen on time you should lover voltages as much as your system remains stable. And choose "power save" governors for cpu and gpu.

Debloat, turn off wifi, facebook & messenger when you don't use them.

With the default voltage setting the processor is very power-hungry.

Default value on most kernels is about 1.1V@2.6GHz.

It's usually adviced to lower all voltages (swipe right "Apply on boot" toggle in KA) by 25mV.

But my device works well at about 1010mV@2.6GHz and 610mV@300MHz.

Emotion kernel V27 cut from the last Emotion ROM works good on 1010mV. RamKernel RC3 hangs up when device is blocked, but overall performance is better compared to the Emotion.

Now I'm testing RC4... no problems so far...

My kernel auditor profile and list of disabled packages is attached (you can export pkg list with BK Disabler, but I don't use nfc, file sharing, samsung account and many other features... so be carefull).

[Galaxy Note 4 Original Android Development] Tesla:
IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT

For all you users of Magisk. Read this.

SafetyNet is updated so you need to put Magisk into core only mode to pass CTS. All modules will not work in core only mode.

You do that in Magisk settings.

There are a new version of Magisk out now too. Try if all else fail.

Magisk Beta: v13.0 (b3da28e)

There are repports of Magisk modules not working with Beta: v13.0.

You have to try and see what works for you.

Hi Ram,

I am 915T user, on RC3 for 915T we have Edge feed function like stock (swipe finger along the edge screen while main screen turn off). But on RC4 we lost this function.

Could you please get it back.

Thanks. (Sorry for my English)

[MENTION=5229173]Ram121[/MENTION]

Thanks, buddy kernel works great .. this time even the phone stays cooler when compared to RC3 haven't faced any abnormal heat or lag,

just one issue it's not even that big issue might me just false touches from my end .... what am facing is when you switch DTTW feature the phones gets woke up even on the mildest touches sometimes in pocket at times just by touching/placing palm on it , can there anything which can be done at this end like any kind of reduction to the sensitivity or anything like that,it's not bothering that much just felt like letting you know.

Again thanks for your work :)
[Galaxy Note 4 Original Android Development] Ram121:
The edge feature is ROM feature it is not because of kernel, please check what changed while flashing kernel and report.
[Galaxy Note 4 Original Android Development] Ram121:
Yes it is expected to be cooler, i will check of something could be done for sensitivity of DT2W

[Galaxy Note 4 Original Android Development] stajam:
Hello, can you elaborate on the battery life with RC4? Iam on the N910V running RC3 permissive on PETBEDE_Note7_Port_v19 ROM. I noticed the OP says to leave all the settings as they are for performance, but I would like to know how the battery life is. I would prefer something pretty well balanced between good SOT and performance. If battery life is subpar, do you have any idea on what settings will help to get decent SOT out of it? I am currently on RC3. Thank you in advance.
[Galaxy Note 4 Original Android Development] xdauserr:
I can't compare to RC3 because It wasn't stable on my N910F.

I have now 1.5 days with of run with moderate usage on low voltage profile, with default governors.

And that's with 90% initial charge. I prefer to use external charger because the phone significantly overcharge li-ion.

That's one of the coses to changing batterys avery year.
[Galaxy Note 4 Original Android Development] stajam:
Dang, pretty good. What screen brightness level do you normally have it set at. I typically have mine set at 50% or so during the day and down low 10% or so at night. I have never really messed around too much with kernel auditor to adjust the kernel settings. Not sure how the whole low voltage profile works.
[Galaxy Note 4 Original Android Development] xdauserr:
I'm a computer hardware and software engineer for 15 years now. All this time I was overclocking processors very often.

FIRST THING TO DO IS FIND OPTIMAL VOLTAGES FOR YOUR CHIP.

Don't be afraid to lower voltage till you get semi-stable system.

The kernel will boot with default voltages next time (even if not, you can flash kernel through recovery which have it's own independent kernel)

It's enough to test idle and full power. Do it in antutu and/or StabilityTest (ROOT optional) for eg.

After finding semi-stable value you should raise voltage back about 10mV.

My phone was very hot, but now it runs stable and cool.

BTW, high pulse current is another battery killer.

---------- Post added at 08:50 PM ---------- Previous post was at 08:47 PM ----------

Place it to the path KA saves profiles.
[Galaxy Note 4 Original Android Development] stajam:
Thank you for the info I do appreciate it very much. What do you mean by high impulse current, are you referring to the rapid chargers? Thanks.
[Galaxy Note 4 Original Android Development] xdauserr:
Answering your question: it's the same as I had on Emotion kernel, but with greater performance.

And finishing li-ion dispute:

I have 3 batteries. (all are good copies from china, with capacity equal to original, with nfc antennas)

One I could leave in charger. The second - in phone and the third is ready to replace.

This provides normal charge voltage, optimal charge cycle usage and long time on the go.
[Galaxy Note 4 Original Android Development] stajam:
I've been using the RC4 kernel on my N910V for about an hour now and I have had two random shut downs while using Google Chrome. After the first time it shut down high powered the device backup went back into Google Chrome to try and finish what I started and it shut down again. Seems odd it would shut down just using Google Chrome. The only thing I have done to the kernel was I enabled the DT2W feature. That's it. Has anyone else had this issue with Google Chrome or any other app while using the RC4 kernal? I previously had the RC3 kernel installed and it was working fine. Any help would be greatly appreciated, thank you in advance.

I don't think it's the kernel. I put my old battery in (which dosent hold a good charge anymore) and have been on Chrome for awhile and not 1 reboot. Maybe time for a new battery.
[Galaxy Note 4 Original Android Development] xdauserr:
I was talking about high CPU currents. They change very rapidly.

Current–voltage characteristic of CPU/GPU chip is not linear. Current increases significantly with tiny voltage increase, when it is close to maximum voltage value chip can handle.

Default is 1115mV@2.6GHz. At this voltage my phone is VERY HOT.

But it's stable even with 1020mV. Only 95mV lower, but now my phone is COOL!!

I'm NOT trying to say every chip could do so.

Find you optimal values yourself.

So let's figure out why my phone got cooled.

Let's conduct a simple experiment.

(all are real values for my device)

Idle current is 223 mA with screen on and no background activity.

(almost all is screen power consumption, measured in Elixir2)

When load test is running (app "StabilityTest (ROOT optional)" ):

1) At 1020 mV: CPU consumes 1286 mA (idle current is subtracted), real CPU frequency (due to thermal regulation) is 2265 MHz.

This means CPU consumes 1.215 W power.

2) At 1115 mV CPU consumes 2059 mA (idle current is subtracted) real CPU frequency (due to thermal regulation) is 1651 MHz.

This means CPU consumes 1.75 W power.

But for the same computing job (due to lower frequency) we get 2.4 W!!

This is TWICE THE POWER!!!
[Galaxy Note 4 Original Android Development] stajam:
<br />

Well I just tried my stock browser and it happened again. Another shut down only while using the internet browsers. Very odd. As soon as I figure out a way to do a logcat I will report it.
[Galaxy Note 4 Original Android Development] xdauserr:
For the li-ion/li-po battery to have a long life (few years) it is advised not to exceed 0.3C discharge current.

It's about 1A for our 3200mAh battery.

As well as extremely high charge voltage (4.4V instead of 4.2V) kills battery. It's done to make 3200mAh from real 2500mAh battery.

DON'T USE FAST CHARGE AND DON'T CHARGE BATTERIES IN THE PHONE.

Samsung is interested to sell new phones and batteries... that's sad.

[Galaxy Note 4 Original Android Development] HappyPlato:
Using N910T version of kernel, rooted with SuperSu v2.82. RC3 was fairly good. Once I upgraded to RC4, I found it's not as stable (didn't change anything or lower voltage). For example, just now it's crashed while I played "Word Streak", then phone just turn itself off. I turn it back on, the phone is now unstable(not usable). This could be just my phone not playing well, I decided to go back to V5.

Maybe I'm in the minority, but instead of getting more features in the kernel, I would like to see more stability fixes.
