[Galaxy Note 4 Q&A, Help & Troubleshooting] iba21:
Guyz, i'd want to spend 2 words about the necessity of overclocking ca53 cores..

Why they goes to 1.3ghz and not hight freq as ca57?

Because off energy efficiency

Ca53 are cores build only for energy efficiency, it means those are build with an hardware lithograpic logic witch decreases transistor's consuption at low freqs, but, it do it at opposite with hight freqs!!

It'a unusefull to increase too mouch the ca53freq because there will be a situation when the ca57 spend less energy to compile the same charge than the ca53! And it's the worst case since the logic is:

All possible computed by little cores, the other by big cores.. as like a turbo charge

As like diesel engine

You have low energy consuption while you use car in "eco" mode.. when you need performance, turbo get in to boost up the engine with huge energy consuption

so.. if you increase the ca53 freq, it means you are powering up the base engine, it affects efficiency.. it affects the base big.little.GTS logic
[Galaxy Note 4 Q&A, Help & Troubleshooting] Lodix:
The question is where is that spot ? Because the Snapdragon 810 will have the Cortex A53 at 1'6GHz so maybe around 1'5GHz will be fine.
[Galaxy Note 4 Q&A, Help & Troubleshooting] iba21:
Yep snap 810 is the same chips as 5433

So.. since lancia delta s4 could reach 640cv (HP).. all 1.8 4 cilinders + turbo can reach that power..

:thumbup:
[Galaxy Note 4 Q&A, Help & Troubleshooting] Lodix:
I am not saying that they are the same chip (?)

But both have the same architecture and the same process node of 20nm. And since the difference between the frequencies is around of 100MHz in the CPU they may have a similar power comsuption.

1'9GHz Cortex A57 in Exynos and 1'9X in the 810.

1'3GHz Cortex A53 in Exynos and 1'5X in the 810.

Not to mention that mediatek has implemented an 1'7GHz Octa A53 in 28nm, but that is another story.
[Galaxy Note 4 Q&A, Help & Troubleshooting] iba21:
There are different arch build.. as the "asv".. it's important not obly the transistor dimension, the purity of the lithographic process and many more

You could have a stable ca53 chip, you should increase voltage too mouch.. too voltage = too energy consuption

[Galaxy Note 4 Q&A, Help & Troubleshooting] Lodix:
Andrei knows about that, there is a problem with the drivers of Samsung. Every time you turn off the screen the frequency will set to the stock=1'9GHz.

No problem [emoji14]
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
I'm running at 1.5 and undervolted and my power consumption remained same as stock 1.3. I guess that's generally the point where you don't want to get past cause voltage gets too high and it's cheaper to have things on the big cores at that point.

Power is about 13*f*V^2 on little cores and about 55*f*V^2 on the big cores, and you don't want them to intersect too much if at all.

---------- Post added at 01:44 AM ---------- Previous post was at 01:35 AM ----------

The big cores get hotplugged on screen off and lose their settings. Anyway it's pointless to oc them, they're running too hot anyway. You'll get better perf from undervolting because the power manager will throttle them less.
[Galaxy Note 4 Q&A, Help & Troubleshooting] iba21:
How you know that formula?? :p

Anyway if that is correct.. my actual voltage set can use ca53 at 1.8ghz with that voltage (if stable) and have little less power consuption than the minfreq of ca57

Anyway the main question is: what's the difference in power calculation?

Because, if 1 core of ca57 needs, for ex, 1 "time" to compile a task, and it absorbs 2x than the equally ca53.. and if the ca53 needs 3 "times" to compile the same task by using 1 half of energy, in all of cases ca53 absorbs more energy since ca57 goes to idle faster than the 53..

I know that's pure filosophy :p
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
I measured it.

A57 are about 1.87 more efficient in performance per Mhz and 4.23 times less efficient in perf/W outside of voltage droop.

I do realise Andrei asked us to post any issues with kernel on github, but I just cant figure out how to use that site properly on my mobile... so I will just post one thing that I experienced.

Using 13.7 version for N910U, I am getting an error for installing an application from googleplaystore.

The "issue" talked about earlier in the thread, regarding problems storing/saving to extSdCard, might be related to the Android 4.4.x bug of R/W access to the external storage. There are a number of ways to overcome this, most of them discussed already here on XDA. Just search for it. You can edit the permissions file, install an app from the Playstore to fix it for you, or use Wanam Xposed to fix it...

For some strange reason I cannot flash any other kernel except Perseus 13.7 Alpha.

I have tried to flash stock, it shows the flash was successful and still have 3.10.9-perseus showing as the kernel version in About Phone.

I was using CWM (1113) then changed to TWRP.After flashing the phone just boot loops on the Android Note 4 screen. I even tried using Odin via PC which worked and booted normally but still had 3.10.9-perseus.

I love the Perseus kernel but I use speaker on the phone a lot and people can't hear me properly so I need to get back to stock.

Any help would be appreciated

Hello [MENTION=4167023]AndreiLux[/MENTION] I had a somehow similar issue and posted about it in the previous page. Whenever I tried to flash another kernel, every app started force closing as soon as the phone booted. I tried several times with the stock kernel and Adam kernel. All I could do was re-flash Perseus to get it to work again. Finally I had to re-flash my rom to return to stock kernel. Still don't know what happened.

Guyz.. if you want to change from a modded kernel to another the good way is to reflash the whole rom and after that flash the kernel

It's not necessary to wipe data too.. only system cache and dalvik
[Galaxy Note 4 Q&A, Help & Troubleshooting] Silverbolt:
I did try re flashing Sweet Rom v7 again but it caused many apps to force close on start.

I am trying to avoid a full wipe because it takes a long time to put all apps back on again.

I tried flashing the Ultimate Kernel 10 even though it is for the N910C and interestingly enough it worked even though I was not able to get any radio signal.

Again I was not able to flash anything but Perseus back.

I am wondering if it has something to do with SE Enforcing????

I probably won't be doing anything regarding GPU clocks because the GPU already runs hot at its maximum clocks and there are like 5 different max frequencies and exposing them is just going to cause confusion.

Hello, I have SM-N910C, stock rom, just rooted, installed modified TW (5x6).

I rooted and installed TWRP 2.8.3.0.

I installed Xposed framework + Wanam and make some modifications + I added module for enabling XSecureStorage.

Today I tried to install Perseus Kernel and after install, there's not been any updates (when booting up system, there are usually "running updates e.g. 1....180 from 180".

Then in system settings in about column, there is perseus listed, but Im missing the app related to tweaks.

So I tried to isntall TWRP 2.8.4.0 from recovery, installation succesful, but after recovery reboot, there is still 2.8.3.0.

Same story is for Philz Touch recovery, if I install whatvere from recovery, it says it is installed, but really it is not!

Only if I install it via odin.

Can you please help me somehow?

And what about the tweak application for Kernel?

Shouldnt be installed into system also by flashing kernel? Or should be app downloaded manually?

The speakerphone bug is my biggest concern, starting to impact my ability to make work related conference calls.
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
I finally had some time to take a really deep look into that today and had a breakthrough into figuring what is wrong.

Samsung is using the audio SoC's equalizers (EQ1,2,3) to synthesize audio input from all 3 microphones when in speakerphone communication mode. I was totally unaware of this fact until today. This caused a problem as I was actually using equalizer 3 & 4 for the speaker at all times but the audio framework was using those at the same time, resulting to funky audio routing.

I'm currently rewriting the audio pathing to see if I can solve this without losing functionality. Equalizer 4 seems to still be free for me to use. Will update when things work.

Hello Andrei. Firstly I would like to thank you for your amazing job with perseus kernel for all those years. Actually I have Galaxy S4 with your kernel and this phone was my choice a long time ago only mostly because of wolfson and your perseus kernel. Sound quality is great on my S4 thankfully to you. And I have a question regards Note 4...I would like to buy a Note 4 with exynos and wolfson but someday I read here your post about saying that it is very hard to upgrade wolfson sound quality and equalizer and to be honest I would like to ask you how is the progress in this ? Do you think you can upgrade wolfson sound same how that was in Galaxy S4 and S3 ? if yes then after upgrade what you can say about SQ in Note 4 ? is it better than S4 for example ? Please in a free time try to reply. I'm just right now like "buy or not to buy" guy who is not sure (I would love everything in Note 4 but SQ is very very important to me).

Big thanks to you for galaxy S3 and S4 perseus kernels. I had them both and they were great. Still have my S4. Thank you !
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
I haven't been able to advance on the equalizers without having the chip's datasheet or a WISCE test-bench for the chip, the register formulas are too complex for me to randomly figure them out.

I think you're giving a tad too much credit on the S4 because I didn't do too much in terms of headphone quality. Samsung's own equalizer in the adapt-sound settings is also high quality, I advise people to try that one out.

Sound quality is good on the N4, but I'm not really an audiophile. The best investment is probably a really good pair of in-ear-headphones.... I'm still rocking these things that I got from Huawei and they're amazing: http://www.oppomart.com/huawei/huawei-am180-earphone.html

I regret not making a screenshot, to post it here. Other than this everything else is working fine, and I am really excited to see if you figure out the equalizer part for the headphones because i like deep rich bass that now with stock sound it is not present, and Viper4Android is a bit buggy on the Note4, and the developer has paused his development for it :(
