Thanks for the frequent updates. I am installing 9.2 as i type this. I know the kernel hasn't "settled in" yet, but from what I can tell it seem as if 8 was getting a little better battery. It could be the difference between on-demand and conservative? I am sure that once 9.2 settles in with a full charge or two, that it will be better than 8. Thanks for all your hard work!

In case someone was wondering the difference between on demand and conservative (I was), I found this from the set-cpu's website.

ondemand

Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.

conservative

Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
[Samsung Galaxy Nexus] bakedjake:
I'm getting the sync drop as well, but I'm on bigxie 6, franco 9.2, and UGKK7 on t-mobile.

This is after a full system/data/cache/dalvik wipe.

What's odd about the sync drop is that it seems to be syncing for some apps but not others. Gmail syncs fine, but the market is inaccessible.

I'm going to try and wipe and install Bugless Beast with this kernel and see if the sync drop happens.
[Samsung Galaxy Nexus] Hypercore:
Am I the only one not able to download the new kernel?

I click it and nothing happens. I've copied the URL and pasted it up to but to no avail.
[Samsung Galaxy Nexus] ChongoDroid:
Had a weird sleep lock where when I locked the screen it would take a few to kill the back light. The phone would wake instantly but the screen took an extra second to go to sleep. It would be a black (backlit) screen before actually turning off.

Edit: nevermind 9.2 fixed it

[Samsung Galaxy Nexus] ChongoDroid:
On a possibly unrelated note, does your phone make a very quiet pop noise after any of the ui sounds? When I listen very closely I can hear a slight hiss and a very quiet pop about 2 seconds after a lock sound or a touch sound. Just wondering if this can be fixed with software and if so is it kennel related.

Remember it's quiet enough that you would have to put your ear to the speaker.

I've had this issue out of the box (it's most noticeable with high quality IEMs), so I don't think it's kernel related.
[Samsung Galaxy Nexus] jknisley:
I had that with mine when I got it. Unbearable static and popping on any sound activation. I had to take it back and exchange it after three days, and I went to a totally different store for a totally different lot. Got the new one and all has been hoopy since.

Try another browser, and/or reboot.
[Samsung Galaxy Nexus] ChongoDroid:
Yes same, sorry I should've specified this didn't happen because of the kernel. Mine also had this problem out the box.

[Samsung Galaxy Nexus] Dr_Ownage:
Like what Kjwalker says above, basically as the kernel changes the battery stats gathered from other kernels/old kernels can become inaccurate. so to get better battery drain every now and then wipe your battery stats. maybe once a month or two if your on the same kernel and if your changing from another one to franco wipe them. or every few upgrades franco makes.

note i said change to franco not change away. i know that once you get here you never leave :P
[Samsung Galaxy Nexus] ChongoDroid:
So your new handset doesn't have the same noise? That's very worrisome because I bought mine off ebay.

[Samsung Galaxy Nexus] edgeicator:
According to this thread, at least on the Nexus One, there is no correlation between battery drain rate and battery stats.

Honestly, I would assume that this applies to all modern phones as well.
[Samsung Galaxy Nexus] dadsterflip:
so hows everybody liking this kernel? im thinking about jumping on to this and it looks like it has some awesome features and always being rewamp to newer and better versions.

only concern i have is and might be a dumb one at that. i see that when the phone is off the cpu1 is shut down then turned back on when its on. wouldn't that be bad in the long run? or short run? as far as shutting down then turning back on again etc?

or am i putting more thoughts to this than i have to?

would like to hear some peoples thoughts on this kernel and thier experiences.
[Samsung Galaxy Nexus] cancerouspete:
recently, i've noticed this often in the logcat that wasn't there before:

sdwatch - Error 4 reading event buffer (interrupted system call)

get that about every 45 seconds, sometimes more often. i read there were changes to the sdcard binary

on request i'll send you the logcat i saved if you think this is related to your kernel. I'm running bugless beast 1/2/12 toro
[Samsung Galaxy Nexus] Dr_Ownage:
I can't believe that at all. (Haven't read the article I'm out and about just commenting on what your saying)

Here is a perfect example as to why battery calibration is essential
[Samsung Galaxy Nexus] franciscofranco:
Yes please, send it over.
[Samsung Galaxy Nexus] franciscofranco:
There is no interface on stock kernel to change fsync settings, it's just enabled by default.

R228 384 doing well here, no 512 gpu today? Yeah I'm a flash junkie, can't deep sleep w/o my fix :eek:
[Samsung Galaxy Nexus] franciscofranco:
r230 very very soon, just testing some ****.
[Samsung Galaxy Nexus] LNJ:
Awesome. Any possibility of freeing up more ram from GPU allocation?
[Samsung Galaxy Nexus] jauhari:
For me. 3 hours is good enough. Mostly I am only get 1-2 hours screen time :(
[Samsung Galaxy Nexus] franciscofranco:
Nope. In case you didn't notice our GPU is a ****ing weakling and we're powering a 720p resolution screen.
[Samsung Galaxy Nexus] franciscofranco:
r230:

* Merge all patches from mainline kernel from 3.0.31 to 3.0.38

* Some tweaks to Ondemand for better performance/battery balance

* Undervolting should work properly now

* Some other stability patches for the higher frequencies

* Some other little code changes available on the github repository

Ok I'm going on vacation for a week so I won't be doing any kind of kernel compiling, troubleshooting or whatever is related to Android in this forum starting from tomorrow.
[Samsung Galaxy Nexus] LNJ:
Lol no ****. But I don't really play games and would prefer my third or fourth app in the background not having to reload itself each time I go back to it.

Never had an issue multitasking with my I9100 which had 835mb available!
[Samsung Galaxy Nexus] The Gingerbread Man:
Awesome :)Enjoy your holiday, I hope your going somewhere nice! :cool:

Having more memory poll doesn't mean your apps will reload or not. I never have reload problems, I usually have 350mb free.

[Samsung Galaxy Nexus] creeve4:
What is the preferred governor for the GNex with this kernel? I've been using Wheatley which has been good to me.
[Samsung Galaxy Nexus] LNJ:
How do you have so much free? Do you limit the number of background apps in Developer Options?

The most I have free is 135-150mb.

On my SGS2 I have 300-400mb free.
[Samsung Galaxy Nexus] WitchMX:
Flashing! :)

Enjoy your week off dude!. Thanks for the great work
[Samsung Galaxy Nexus] franciscofranco:
I don't free anything. I use this kernel + MiNCO with nothing else changed. I just don't have crap apps running - I control my device, not the device controlling me.
[Samsung Galaxy Nexus] LNJ:
The problem is that I have the exact same apps running as I did with my SGS2 so I was hoping that the GNEX would handle apps the same way but seems not.

Oh well at least I have JB and a 720p screen!
[Samsung Galaxy Nexus] :
Just flashed r230 (384) on CM10 Skank. r225 was the best kernel ever for me on Jb. Anxious to see what this does..Tks Franco. Have a good vacation man!
[Samsung Galaxy Nexus] yahyoh:
:eek::eek: running many apps here with always free ram between 300 -250 :p on Gnex
[Samsung Galaxy Nexus] LNJ:
The only difference is that I have Google Now, NFC and Wallet on.

So maybe those are the culprits....but I like Google Now....
[Samsung Galaxy Nexus] franciscofranco:
NFC and Wallet only need to be activated when you actually need to use them...
[Samsung Galaxy Nexus] LNJ:
I use Android Beam very often so I just leave it on. As for Wallet, I could turn it off!

Turning off Google Now only gained me 30mb.

I love that place, been there twice already. I don't know if you been there already or not but I recommend a bar called the travellers bar, its this smallish kind of place open all times of day and you can get your self booked into bar crawls (if that's your thing) its down Las Ramblas which is a really happening street, loads going on down there its a really happening place. The bar I mentioned is near the ocean / sea on the left side if your walking towards the sea off a small street 100m in on the right side of the road. Also right down by the sea there's this night club built on the pier, I took an ex girlfriend there for her first night club experience. Trust me youl love that place, I love Barcelona its a fantastic city and want to go for a 3rd time one of these days.

While there I got this painting, watched one of the people down Las Ramblas spray paint it in front of a crowd of people and bought it for €20. I'm actually quite envious now you lucky lucky guy!

Sorry for real bad off topic guys.

R230 is great and definitely can tell the difference, I love the 512 GPU and this performs great, can really tell the difference from running lower GPU for a day or so.

"Since 50m,".. 16m.. 1h23m?

You haven't been running your phone long enough to properly evaluate your wakelocks. Fully charge, close all apps in Recent (you should be doing this regularly anyway), THEN unplug from the charger, turn off your screen and leave your phone alone for about 6-8 hours. Then show us your Kernel, Partial and Alarms. :)
[Samsung Galaxy Nexus] RoscoeDpG:
dontation headed your way tonight to get yourself a nice drink and snack :D
[Samsung Galaxy Nexus] TEK112:
Agree with this.

Although, he can use the phone, it doesn't have to be off. Problematic things will peak through although it would be best to allow the phone to try and sleep for long stints.
[Samsung Galaxy Nexus] supernova_00:
So if I don't have "Deep Sleep" showing in better battery stats I'm assuming that means my phone doesn't enter deep sleep?

Also, probably off topic for this thread but how the heck can I troubleshoot why my phone shuts off here and there? Is there any kind of log I can get? And yes I searched here and google to no avail.
[Samsung Galaxy Nexus] osm0sis:
The longer it's left alone the more you can see how well it deep sleeps. If that's too difficult then sure, TEK's right, it won't mess up the stats too much if you use it a short amount of time.
[Samsung Galaxy Nexus] TEK112:
Download CPUSpy from the market (free) and run it once. Then turn the screen off and pick it back up in 30 seconds. See how long it has slept. I use that app all the time, it is straight forward and tells you how long you spend at each CPU frequency.

Definitely, the longer you can go without turning the screen on, the better... my record is 7 seconds...lol

[Samsung Galaxy Nexus] nikulogical:
Is there any disadvantage (performance or battery) too undervolting a frequency too low, even though it runs stable?
[Samsung Galaxy Nexus] Burninh2o:
Sorry but what is the purpose of paid app vs this? I just got into smart phones. I don't really know what the purpose of "kernal" is. Was searching on the nets about overclocking g-nex gsm and came across this thread + paid app...what is the adv of using a kernal is something I would really like to know. Don't downvote me for asking such elementary questions to old-timers. thx
[Samsung Galaxy Nexus] ssCISengineer:
What does this mean?
[Samsung Galaxy Nexus] DarkBanHammer:
No just better battery
[Samsung Galaxy Nexus] mariachi202:
Hardly noticeable better battery. I would say that the main advantage of undervolting is lowering the overall heat generation, ergo cooler phone.
[Samsung Galaxy Nexus] Burninh2o:
Why should I use this on G-Nexus? I would like to overclock my CPU, there are many free apps for that. I want to increase sound, there is Volume +....I don't plan on doing any other tweaking to my G-Nex GSM w/ jb. Now, why should I use this? Don't take it the wrong way, I am not asking/saying this in negative tone. But can you please tell me (not a very "customization" savvy android user) what I will benefit from using this. Also, what is the point of paid app when it's for free here? Again, don't flame my post for asking such novice question.

Thank you
[Samsung Galaxy Nexus] nikulogical:
You shouldn't be flashing anything if you don't know what a kernel is. Not saying in a negative tone but you should read up some stickies and faqs before you get into custom roms/kernels.
[Samsung Galaxy Nexus] mariachi202:
First of all, you don't need to buy the app, nobody is putting a gun against your forehead to do so.

The main reason why you should buy the app is to support the developer, in this case, our '****ty' Franco! :cool:

Otherwise, you could use terminal commands to accomplish what the app can do in a breeze, if you consider yourself savvy enough for linux based commands.

The kernel itself is free and always will be.

And if you are not familliar with flashing terminology (CWM, kernel, rom etc.) i suggest you read a few articles. Google is your friend. Cheers.
[Samsung Galaxy Nexus] mtmjr90:
Agreed. Also...CAN you even OC the stock kernel? When I first flashed JB a few weeks ago, I was using the stock kernel and setCPU didn't let me OC...or maybe I'm remembering wrong.

Anyway, francokernel does a lot more than just overclocking and sound tweaks... The app isn't necessary, but it supports the dev and it provides an easy way to access all your kernel tweaks rather than spreading it across several different places on your phone.
[Samsung Galaxy Nexus] mariachi202:
No, the stock kernel cannot be overclocked, only downclocked.
[Samsung Galaxy Nexus] nikulogical:
1200 is the highest step so no.

Please visit the Soccer Mecca: Camp Nou. That should inspire you to pump out more awesome kernels

[Samsung Galaxy Nexus] asicman:
For battery savings its better to underclock rather than undervolt. Undervolting is a good feature, but I'm not particularly excited about it.
[Samsung Galaxy Nexus] nikulogical:
I value performance over battery life and I've dropped down the 1420 freq down so that SR calibrates it to 1230mv. Same mv as it calibrates 1200 freq.

Wondering if anything would be compromised.
[Samsung Galaxy Nexus] simms22:
if you want performance, dropping voltages is usually not the answer. you might loose performance by undervolting. if you want performance, keep you system clean of **** apps and keep it to the bare minimum of background processes. some of us go as far as deleting all the system apk files that we dont use. for me thats 15 system apps that my device doesnt have to deal with.
[Samsung Galaxy Nexus] nikulogical:
This is what I've been trying to figure out. I've been running benchmarks and stability tests with 1420 step running on the calibrated 1230mv and the preset 1325mv. I haven't noticed any differences.
[Samsung Galaxy Nexus] simms22:
you probably wont notice much of a difference unless you too high or too low.
[Samsung Galaxy Nexus] Burninh2o:
Guys, thanks for your responses. I totally get the "support the dev" motto of xda. So far, I only got one app (which I paid for) within a couple days of owning G-Nex (there was a free version of it too btw). :cool: + :angel:

I guess I will buy this app too since it will let me overclock my CPU w/o involving my top-notch cmd typing skills...hehe iKid.

Also, is Volume+ worth getting if I get this app? :confused:

Thank you :cowboy:
[Samsung Galaxy Nexus] simms22:
i dont waste much time playing with voltages. the only time ill put time into voltages is to get stable at a much higher clock speed. other than that, i already know that my phone like 15mV more than the default at 1536mhz(trinity).
[Samsung Galaxy Nexus] nikulogical:
thats what I figured.

So going from max freq of 1228 volted at 1230mv to 1420 volted at 1230mv, it would use the same power correct? But offer higher performance?
[Samsung Galaxy Nexus] LNJ:
You can get the Trickster Mod app which is free and allows you to set pretty much all of the available settings.
[Samsung Galaxy Nexus] imablackhat:
Does Franco kernel make it so when making a phone call the proximity sensor doesn't work and you can turn on and off the screen yourself? Or do I need to pull my battery and yet reset the proximity sensor. I just came from trinity.
[Samsung Galaxy Nexus] c_86:
This app is a partner to the kernel.... this app is useless unless you have Franco kernel installed.... you can't just install this app and hope to overclock the CPU... you need a kernel to support the over locking ...
[Samsung Galaxy Nexus] nikulogical:
Proximity sensor should work. It always has.
[Samsung Galaxy Nexus] TEK112:
I wouldn't say it is useless unless you have Franco's kernel installed. It works fine with imoseyon, trinity and lean kernel. In fact, it works fine with any kernel I have tried and I have tried them all.
[Samsung Galaxy Nexus] asicman:
No. Even if voltages are the same, the higher freq. will use more power because internal circuitry is clocked at a higher freq. Flip flops will be switching faster which increases dynamic power which implies more power dissipation.
[Samsung Galaxy Nexus] imablackhat:
Guess I'll have to reset mine again.
[Samsung Galaxy Nexus] c_86:
meant it more along the lines of if you are using the stock kernel you can't use the app.
[Samsung Galaxy Nexus] TEK112:
In that case, yes sir.

Underclocking is about the only thing it would be good for.

[Samsung Galaxy Nexus] jcmm11:
1.905 was just released on the 28th. The following is posted on the volume+ web site concerning this release. Note especially the 2nd paragraph:

I’ll be on holiday from today (the 28th) until the 4th of August so If I haven’t replied to your e-mails I will try and get round to them when I get back.*I will also upload the free version on the forums when I get back as I do not have the time to do it now.

Before I get about a million comments along the lines of “Does this work on JB yet?!?“, let me just say that no, It does not. Despite the fact I’ve stated it a million times before, I will repeat it:*you will know about it when (or more importantly, if) I can get it working on Jelly Bean. I will make sure everyone knows it is compatible. Until then, please try and be more patient.

This update doesn’t include anything new but does include a few little bug fixes.

For me, 230 brings an unwelcome issue. I've replicated this 3 times by restoring to stock rooted and then reflashing 230...

I lose USB / ADB connectivity. The device isn't seen by the pc, either as a media device, or as an ADB connected device. Rebooting the device and pc (and reinstalling drivers) doesn't help matters. Very rarely can the device be seen as a media device (about 1 in 10 reboots), but it can never be seen as an ADB device after the first reboot.

Weird.

[Samsung Galaxy Nexus] nobnut:
I beg to differ, the problem is clearly an issue (for me) when using this kernel with the ROM I am using. As I said, the stock rooted kernel doesn't cause the problem.

I'm not bothered by it and am not complaining. I was just commenting.

It's great that it works for you, hence my comment.

EDIT: USB Fast Charge wasn't on ;) I didn't even have Franco's app installed (which I have previously bought), as I was just wanting to test his latest work.

Try reflashing your radio, rom and kernel with a full wipe (data, cache, dalvik, format /system).
