[Galaxy S II Q&A, Help & Troubleshooting] Sander M:
Hi all,

Scenario: got tired of unstable custom ROMs, did a full wipe(/data/system/cache) flashed stock rom (4.0.4 XEN) for my region. After setting up the first time ran Odin again to root with new Siyah v5.0.1. Got rid off Vlingo using Apex launcher trick(or Go launcher EX).

Now I noticed tonight I no longer have any home button lag with only the above changes to my phone. In other words happy me. However I cannot find any suggestions for any home button lag fix in Siyah's changelogs while the Vlingo assistant with it's annoying lag was present at first boot before kicking it off with the launcher trick. Now this used to result in no more Vlingo but still lag when pressing home.

Does anyone know if anything changed in the Stock rom 4.0.4 or Siyah 5.0.1? Don't get me wrong, happy with the result :) Just curious.
[Galaxy S II Q&A, Help & Troubleshooting] naeads:
This is just from personal experience of using my galaxy s2 and by no means an expert...

But I never use the stock rom (with the exception of gingerbread) because anything after gingerbread lags like hell on my s2.

The only reason I can think of are the bloatware from samsung taking up all the hardware resources of the phone, thus slowing it down. Whereas I find most custom rom "cleaned" up the phone and require less resource to run.

I don't believe there is a problem with the kernel but I can be wrong!

If you are afraid of unstable custom rom, why not try CM9 stable mod? It has served me greatly.

I thank those who give helpful comments

I expect the same from others.
[Galaxy S II Q&A, Help & Troubleshooting] Sander M:
This isn't about bloatware but the delay which was programmed into the stock to wait for a second press on the home key because of voice commands/Vlingo. In 4.0.3 deleting Vlingo did not fix the lag because it was hardcoded in the stock ROM.

So some finicky things have happend since I got my Note 2 last week.

First is that when I enable speaker phone, im muted and whomever I call can't hear me. I verified this using my wife's phone.

Second, I'm coming from a Galaxy Nexus and a lot of the functionality of Google Now seems lost. For instance, if I say "text so-and-so" it wont do anythung but Google so-and-so...same thing with "navigate" or "take me to" and all other commands...

Did Samsung drop a deuce on Google Now so we'd be forced to use the crap-ball that is S-voice?

Let me know if any one of you has been having these or similar issues.

Also changed my vibrate notification to "heartbeat" but it only does it for calls, not texts.

Edit: running stock, unrooted

[Nexus 7 Android Development] jsmasterx:
I've asked the mods to close my other thread.

What I'll do in this thread is to test kernels and see which will be the best and or the most reliable undervolting parameters.

I know that each CPU/GPU are different, it will be only a reference for what can be done. I'll run extensive tests, stress test and real life test on the Nexus 7 device 32GB.

I'll reserve a couple of post areas because i want it to be a permanant thread and i put my device at risk for you my firends :P anyway it is not really an issue lol

I'll do the testing like that : ( how i'll do it and conditions )

1. I'll write the kernel name and version i am using for the test

2. I'll post the screenshots of the settings and/or a raw text of the settings for the specific kernel.

3. Trickstermod will be used for tweaking

4. Quadrant test for people who live for it :P

The conditions for the undervolt pass the test are the following

1. Running glowball for 30 minutes without crashing

2. Running Stability test 2.5 for 30 minutes. ( RUNNING EACH OF THE TESTS FOR 30 MINUTES C-A-D CLASSIC/CPU+GPU/SCALING TEST ) all in userspace mode.

Those settings will be the lower voltage achievable for me. You can use it as a reference but I

cannot guarantee it will work for your device.

. What I can suggest is using the boot delay option from the trickstermod menu. If we see that some settings are reliable for a lot of people, it would be nice to have help from some coders to write an init.d script with those settings. or just sharing other experiences. This is not a thread where I have the ultimate knowledge, but a thread who everybody can share their experiences, settings and so on to achieve the ultimate goal of performance and very low power consuption and battery life.

Those test will be time consuming but it is ok.

I do not expect any form of donation for that

If it helped you a little bit, you can just hit the help button and it will be my payday =)

Thank you very much

PS : For people giving 1 Star to the thread before I ever post the first undervolting settings, well, I do not know what to say. For the others who already tried the differents settings I,ll post day to day, feel free to post comments and rate the thread. You can even rate it 1 star if you want because you tried it. But for people who gave negatives reviews even if i didn't post any settings, please get a life.

400 Mhz @ 750 mv

300 Mhz @ 725 mv

200 Mhz @ 700 mv

100 Mhz @ 675 mv

Notes for this undervolting

CPU stable at 975 mv for 1300 Mhz. Tried 970 mv with -5 incremental for other frequencies but the device just crashed. reverted back +5mv for all frequencies and run a second test and it was 100% stable.

The stock CPU voltage settings is 1175mv for 1300 Mhz and so on by 5mv incremental. We are able to achieve performance and stability with a global undervoltage of 200 mv. Actually this is a lot. What happened with the battery life ? Almost 8 hours gain vs the stock settings. This is a lot considering there is no drop with performances.

Edit : Just made other extensive testing. Played deadzone, dead trigger and gta 3 without any glitches. They run smoothly without freezes. We could assume this config is quite stable.

Next step would be undervolting bus and memory while trying keeping those voltages for the cpu. Ill need help to achieve that because i am not a big coder.

how is the performance is it good because i have a lot of lag when i pull down the notification bar
[Nexus 7 Android Development] jsmasterx:
Undervolting should not impact the performance of the CPU.

What you can do is taking a look at the numbers and raise voltage a little. But it might be a lot of reasons why it is laggy. Possibly the governor ?

Other people tried the same settings without issues. But raisong the voltage a little wont drain the battery a lot as the number I gave are agressively low.

Running stock 4.2.1 with MKernel A19 & TRINITY... These voltages seem to be alright.

I am also using interactive and the deadline scheduler.

All is smooth so far... I'll report back if I run into any trouble.

UPDATE - Had to revert. Started getting freezes and crashes.

Trinity kernel's stock voltages seem to play nicely... Anything less is glitchy.
[Nexus 7 Android Development] jsmasterx:
For underclocking aaggressively for now I only recommand Franco Kernel. All other kernels Causes stability problems with the same voltages.

Ill let you know soon with that developpement.
[Nexus 7 Android Development] krazeecracker:
Can't wait for m kernel optimizations
[Nexus 7 Android Development] jsmasterx:
As soon as they realease the next version I'll test it.

For now the only thing it does is freezing the tablet.

The best undervolting I was able to achieve for now was with Franco Kernel because of the way the kernel is setting up. M-kernel and other boost Bus and memory speed that causes crashes with agressive undervolting.

Doing so, the performance gain is minimal and the battery life truly suffer at the end.

You can get except a few more FPS in certain games but not really noticeable.
[Nexus 7 Android Development] krazeecracker:
No rush man, your work is amazing.
[Nexus 7 Android Development] Metallice:
100% of everything you said in that post is untrue. Please make sure the information you pull out of thin air is correct before stating them as fact.

Also voltage tolerance at a certain frequency is device dependent. Not kernel dependent. No amount of circumstantial evidence will change the laws of physics.

One more thing, your frequency table in the first post is wrong. The A9 G core DVFS table does not go below 480MHz. Franco's table is wrong and as a result so is yours.
[Nexus 7 Android Development] sparksco:
This thread looks interesting. If you'd like you can test my kernel attached to THIS post as a flashable zip.

:beer:
[Nexus 7 Android Development] jsmasterx:
I will. What would you like me to do after ?
[Nexus 7 Android Development] jsmasterx:
I did not attack your kernel whats so ever i dont know why you are taking it personal.

As far as i know franco`s table is accurate and the G core can go under 480 mhz. To make sure i what i advance is true i even pluged the N7 to a debug box. My friend who is an analyst programmer certified it also
[Nexus 7 Android Development] sparksco:
Whatever the goal of this thread is I suppose. It's based on bricked kernel but I modified it a lot so it's not really much like it anymore. To some it up it overclocks to 1.6ghz and has quite a few governors. I'm testing smartassv2 right now but I have a feeling it's not good for battery. I haven't really tested many of the other governors but I've never had any of them lock up on me. Voltage control is also supported. No GPU overclocking though.
[Nexus 7 Android Development] Metallice:
The 4 A9 cores go down to 340MHz on the stock kernel. The voltage tables go down the 480MHz. You can check the kernel source yourself.

I may have taken it personally yes... but it doesn't change the fact that what you said about memory and bus speed was completely untrue and impossible in the case of memory frequency. Additionally bus or memory frequency would have no affect on CPU voltages as they are part of the core. The CPU and Core are separate.

I promise you. The frequencies in Franco's voltage table are completely wrong. Check any other nexus 7 kernel to see the correct ones.
[Nexus 7 Android Development] jsmasterx:
Your kernel is excellent first of all.

2 ill try something out with your new release. I think we will be able to achieve one of the best battery life with this one.

Ill also have the same results with bricked kernel.

Both have the skills to unleash the N7.

Time to undervolt and see what happens.

thanks.for great work, 5 star vote.

I'm using clemsy battery saver kernel because it's the only that I don't get the screen flickering issue at low bright conditions, and also I get great battery life.

Does anyone have any idea about the screen flickering issue?

When I tried other kernels such as motley kernels I could not under volt more then 75mv. It would not pass the stress tests and crash. It was very stable at –50mv.

Maybe I have a bad model, the cpu build is the worse number I checked, and just can't remember now what was exactly the way to get the number.

I'm so surprised you got –200mv

Re: [OPTIMIZATION][UNDERVOLTING} Testing different voltages and CPU behavior

I dont know if this is right (or possible:D ), but here is my results with Stock 4.2.2 + Motley kernel (N7 tilapia):

1200MHz - 925mV

1100MHz - 900mV

340MHz - 750mV

204MHz - 740mV

102MHz - 730mV

51MHz - 715mV

My device is underclocked to 1.2GHz and 416MHz on GPU... FSYNC is off...

I've used Set CPU apk for the voltages, because in Triscker Mod I cant change anything under 500MHz...

Confirmed by 30min on Set CPU stress test and random benchmarks...
