[Galaxy Note II Original Android Development] honki24:
Okay, did some scientific analysis this morning on the drive in on my SPH-L900 in terms of the music stuttering.

I downloaded a whole CD from Google Music so that I wouldn't be streaming. This takes data connectivity out of the picture.

I play my music over Bluetooth to my stereo in my car.

I started out with my most recent settings (the only thing changed from default was "min freq for responsiveness" set to 600MHz. (Got stutter 1-3 times per song)

I increased "min freq for res." to 1000MHz. (Got stutter 1-3 times per song)

I increased my minimum frequency from 200 to 800MHz. (Got stutter 1-3 times per song)

At this point I was discouraged and just decided to unfreeze catlog (my logcat app) and take a log. Well to my surprise while taking a log in the background (with the screen off) I only had one stutter in three songs.

My preliminary findings seem to indicate that clock speed isn't the culprit but perhaps rather my hardware allowing a moment of unresponsiveness. Perhaps when a constant background app like a logcat app is running it keeps the processor busy enough in combination with the music app so that the CPU doesn't go into a relaxed state? I dunno... I probably shouldn't be conjecturing. Anyways, I'd have posted the logcat but for some reason it didn't appear to have saved to my SD card when I hit "pause"... sorry.

I'm on the Sprint SPH-L900 but I'm on an LK8 ROM (H20) with the 4.1.2 camera. Mine still works with the 30.1 kernel. See YouTube vid: https://www.youtube.com/watch?v=TzXLCNm4EUQ

Im having strange battery drain with 30.1 kernel. I have onlu used the device for a few minutes using internet and wifi. After 4 hours the battery went from 100 to 87 percent. No other running apps only viber which I used to run previous kernel but only drained less than 1percent per hour.

[Galaxy Note II Original Android Development] AndreiLux:
Thank you.

My point is that he was saying it would be battery efficient settings, which is just empirically untrue, and then he replied about me criticising smoothness and ignoring half of his first post. I call that a smartass. And Entropy's post drives the point, there's a reason the settings are how they are, worldwide mobile companies don't set up their chips like that just to make the user experience lag.

It's easy to make some claim on these forums and then have uninformed people believe it, it's hard to disprove it without having to write an essay on power management.

[Galaxy Note II Original Android Development] betoNL:
Well...to make a long story short, some things are not that hard to prove or disprove ( at least to yourself), when you perform your testings systematically .

And have fun with it :).

But one thing I know I don't even have to try:

Agressively undervolting by disabling the highest frequencies as proposed before..no fun in that ;)

The sensor in not physically broken it is because of the kernel.was on stock on my note and never any issues.

Any chance for some Gamma/ RGB controls for the note 2 kernel?

Is it possible?
[Galaxy Note II Original Android Development] cobraboy85:
Very nice breakdown. And good info...
[Galaxy Note II Original Android Development] AndreiLux:
They are already in the kernel but people will need to reverse-engineer them. I don't have time or the knowledge in image processing to give the corresponding names to each settings.

They are found in /sys/device/misc/mdnie/ and each scenario is applied depending on what you are doing in the ROM and the profile you have active at the time.

Here's the full default settings: https://github.com/AndreiLux/Perseus-S3/blob/master/drivers/video/samsung/mdnie_table_t0.h

I know that "CC lut r" for example is a type of colour threshold control, "SCR RrCr" and so on are RGB controls.

Supercurio has been sitting on the descriptions of these registers for over a year but hasn't shared anything yet.
[Galaxy Note II Original Android Development] Dazog:
I have a spyder 3 and HFCR to calibrate, I just can't code a front end to control the variables to find out what does what.

But with the right person I would be willing to debug it and figure out how to give us proper control of the panel.

Yea I don't even pay attention to what supercurio has he talks alot, doesn't release much.

Thank you for the quick reply.
[Galaxy Note II Original Android Development] AndreiLux:
I will try to make some kind of interface for STweaks but I think I will need to work on the sysfs to making something worthwhile. Won't happen soon...

What you can do is to just "echo 0x0021 0x1090 > /sys/class/misc/mdnie/tune_standard_gallery" (That one is for "CC lut r 16 144" while in ADB and then measure the effect on the screen while you have the gallery opened and you're measuring a picture with the colour calibrators. Then go through every single setting listed in my link and play with them.

It's very tedious work but not everybody has the equipment to do it.

Agree best results with dolphin for me...

Now if the goal is to beat fruite with some figure...yes we can...but what the point though? Sure it is puzling me a dual core can beat a quad one even with less cycle. ..but there must be an explanation...a rational one that is beyond one saying one device us simply better than an other one...with note 2 we are close sometimes better than the "official" fruite score 915ms for what I can see...me got most times 950ms...some of you 904ms..how you explain that? Background process etc... then we are on android...made for numerous kind of HW bla bla...at the end I'm not Einstein. ..I dont need to loop in complex equation / simulation...like you I use it for web email music...mkv playing etc...do a bit of develooment using motodev and thats it..

Battery life customizations is what matters to me...the rest I do on computer

So since we are here and review who as the biggest one...form factor it us :)

But even with sunspider..

So here u go 831ms..for your friend. I let people guess how I got that score :) but its for me irrelevant..all I know is that I'm lucky / happy to hown that device and have lot of fun with it

Tried almost everyting now, uber stock rom only rooted, reflashed perseus kernel and even on stock speeds and voltage peformance drops .

rebooted phone, did benches, all good.

Left phone and watched a movie and did some benches again. Performance is 50% of stock.

Flashed stock kernel, no problems doesnt seem to be bad chip but i also seem to be the only one with this. wth

Well it happens that I had a similar "ghostly" behavior, where after unlocking the screen, the upper cpu limit would magically reset to 1000Mhz... in my case it had to do with setcpu profiles...donno why but something seems to be messed out with them, so I disable them out (profiles), and again all is peachy.

But as I like to combat fire with fire, I just created another profile that resets the speed to 1800 when screen is unlocked.

Yeah I know... I'm crazy xD

[Galaxy Note II Original Android Development] radjeshsitaram:
Thanks, but cpu speed seem to running at the speed it should, all cores. When the issue is there and i run stab test it runs at 1600 or 1800 or what ever is set as max speed, it just goes, i know it sounds weird, slow. And benches give results with half scores but speeds are shown in every program like they should
[Galaxy Note II Original Android Development] CekMTL:
Well yeah but...

But fruity loop ppl always forget that android is running in a VM with java code... so... it's like running windows in vmware and trying to beat a physical machine...you will need more ram, more cpu grunt and more he speed... see...what is fascinating is that we have same or better performance in a virtual machine with java code running, with (stupid) memory management kicking in all the time (each garbage collection run can pause execution of process for many ms even more than 100msec, and then you notice a choppy performance; it's only coz the process has been FROZEN, it's memory compacted, resources freed, and after taking care of all that, the process is resumed again...not the best interactive experience...)

Wohaaa sorry for that off-topic, but there's soooo much going on under the hood... don't forget TRUE multitasking also... you may have in excess of 20+ processes running in the background...so again...

They use Objective-C that has low level access libraries to hardware, and their multitasking is kinda..."walled garden approach".

Ok enough and sorry for this massive off-topic. :p

Hmmmm that seems totally different than what I had... weird...from what you are saying, it gives me the feeling that there's some throttling going on in the background OR a rogue process that is stealing cpu cycles... either way you should have a terminal window open with ssh in you pc and monitor dmesg for some weird messages while you're benching or having that problem.

Top can also be a nice option to see cpu cycles in real time.

Hope this helps you squash that bug!

I'm using omega 3 and the 1.8ghz kernel using apex launcher.

And havent notice anything obvious in usage performance but indeed do not quantify /bench each and every time the device .

So if I understand your issues is that after a while using the device you have about 50% perfornance drop

So this would mean for me since I use the device now for a while and would bench the device lets say tomorrow I should see 50% drop in performance assuming I can reproduce the issue...right?

I can try but how are you measuring this performance drop? Please give some details so we use the same.

Now for the obvious...which I'm sure you did check but let me ask : are u sure there are no background process running at I.e 50% usage at 1800mzh...I ask because couple days ago news 360 app got a problem on my device using 50% cpu and 42 thread reboot fixed it when I noticed it but after sometines it kicked back in...so de-installed it...since I missed it re-installed it and now no longer any problem...its well possible they had problems on there server and fixed it though app fuctioned rigth except continuous 50% cpu usage that would show performance drop in bench but not so obvious to see performance drop in usage

I use cool tool and monitor pernanently process on my device that is the way I noticed. When it is idle it is at 200mhz from 2% to max arround 8% cpu usage never more than 10%

Let me know your detail and will check carefully

Cheers
[Galaxy Note II Original Android Development] radjeshsitaram:
Yeah it is exactly like that, you or for now just me caught the issue with benchmarks.

Stability test just runs, showing the correct speed but the runs take twice the time so it's tricky to see this problem when just testing for stability.

How i found this out, in my case, is i tried this kernel. Was like wow very nice worked perfectly and very stable. Then spent a good amount of time doing benchmarks without much time between them and all with very nice results.

I then went to bed, woke up took the phone did a benchmark (first some coffee ofcourse) and then had like 50% results.

For example take quadrant ( i know thats one of the baddest benchtools but the result is the same in every tool i tested and quadrant is fast with custom cpu test) normally at stock speed CPU score is like 15k. It then was 7k. Did some CF-bench, etc, etc and all showed cpu performance at 50%.

Then did stab test, correct speed show all cores running stable but... Runs only took twice the time then normale. Tested all benches like for 2hours without luck.

Then rebooted phone and all was okay again. Tested for 1h, everything good.

Left phone for 1,5h after intense testing, picked it up again and same problem. Rebooted and okay again.

Wiped reflashed everything, no good same problem

Flashed stock kernel, no problem no drops in performance so i say not a problem with the hardware?

Flashed this kernel again, same problem. Only solvable by rebooting (till now) but always get back.

When the problem is there, no apps eating up CPU cycles or stressing it. When monitoring just 1-5% use.

Can't find problem with low use, browsing or launcher lag. I mean this phone is fast also at 50% lol but with benching and intense programs it is there.

As i dont have this with stock kernel i really think it is something with this kernel it should be reproducable (is that a word?)

Unfortunatly i dont know anyone personal atm with this phone so cannot test it on another handset :(

I hope its a bit understandable how i tell it know. I also kinda hope someone has the same problem, only because then it means its something that can be solved lol

PS

I tried Omega3 too, almost all available rooms to rule out any custom scripting. Now only testing and trying stuff with stock to be sure but no luck :(

This is using the Stweak settings that DakiX posted in this earlier post. Zero problems, everything running smoothly, no noticeable lag. Fantastic!

What do you mean undervolting display?

If you want to reduce battery drain from screen just reduce the brightness.

You cannot reduce power drain without dimming the screen.

Just a small addition, as yesterday I wasn't able to answer the question, wether the SDS-fix is neccessary for the note 2 too.

I extracted the LL7-kernel image yesterday and had a look into the string table to find the entries „CMD13(VC)*failed“ and „VTU00M“. The search was successful - so I conclude that samsung is aware of affected note 2 devices too.
