Anyone experiencing lag try using 200-1200mhz instead of 100-1200. I'm using 200-1200 with lulz governor, no lag whatsoever. Only just flashed b14 since b6 cos I've been away for a while..I Can't believe how much development you've managed while I've been gone gokhan! This is amazing stuff!!! :D Using Checkrom 3.1.1 now btw all.
[Galaxy S II Original Android Development] gokhanmoral:
no comment on min_bl and max_gamma settings?

some people were crying to get those and now nobody is talking about backlight tweaking and lower backlight levels? :)
[Galaxy S II Original Android Development] spaxx24:
I dont understand it.. haha. What values should i put for battery?
[Galaxy S II Original Android Development] WebReaper21:
Well, our displays have a refresh rate of 60 Hz. So, technically there is a difference between 30 and 60 fps and some users will notice this difference, but reducing the cap to something around 45 fps may be unnoticable.

Generally, I think your idea of lowering the cap may be a way to further reduce power consumption while gaming ;)

Of course we would have to test that theory...

Don't become the lowest setting lower! I would like to lower the lowest brightness and the midrange...

And is there a way to force the changing of the gamma immediately so that I can change the profiles with tasker?
[Galaxy S II Original Android Development] :
To me lowest back light is perfect now ;).
[Galaxy S II Original Android Development] gokhanmoral:
hmm I missed that post. well.. changing those values affects only autobrightness response. lowering the lowest brightness is not available (yet). I will do that as well. Although it is not configurable, I tried to lower the lowest brightness but maybe I failed. I will check it again.
[Galaxy S II Original Android Development] :
I tested old and new beta and lowest brightness is lower now. For sure.
[Galaxy S II Original Android Development] cheewaca:
Same here. B14 seems unstable in 3d apps. I´ll try with performace governor.

edit:

stock rom with stock values.
[Galaxy S II Original Android Development] bgx:
Yeah I don't use manual brightness only had use it for testing the impact of the settings!

What I want are two or tree brightnesstabels one bright, one normal, one realy low!

Than I want to use these with tasker! When sun goes down or battery below 25% set lowest brightness table. When the weather is sunny, watching youtube or videos or use camera set the higher profile!

That was I have here at the moment with tasker and screenfilter app and modded framework!

Want to sort out the screenfilter app and implent all the things to tasker!

That would be realy great!

And I think you can do it! ;-)

Hi Gökhan,

Thanks for the betas. I have something in my mind though, I am using Voodoo Screen Tuning App developed by Supercurio, which can be found here: https://market.android.com/details?id=org.projectvoodoo.screentunedev What is does is to change the color and brightness? settings from the lowest level; please have a look at this: http://xdaforums.com/showthread.php?t=1241590 if not already.

How would it be if you left the screen arrangements to this nice app and concentrate on the other system settings :D No offense.

Regards.

I'd like to revert to default Oxygen ROM to do some comparisons.

I tried everything: wipe data, cache, dalvik, flash CFRoot, install oxygen from zip and after reboot it's stuck on "Samsung Galaxy..." screen.

What exactly one has to do to revert to old kernel?
[Galaxy S II Original Android Development] the^one123:
Same Here. Thx for all your work.

I'm using CheckRom3.1.1 with GoLauncher Ex and Kernel B8 at the moment.

Governer lulz with 200:1200 .

I set the same UV Settings (850mv) to 100 and 200mhz so there is no difference in battery usage and the phone is so fast. No lag @ all.

So the decision to go from 100:1200 to 200:1200 is the best i think @ the same voltage. We have a high quality Produkt with very good hardware.

Then we decide to use a cpu clock (100mhz) and wonder that some things are laggy. Sorry but i think UV and OC is ok but UC to 100 Mhz and talking the developer the launcher or games are laggy is not the right way.

[Galaxy S II Original Android Development] WebReaper21:
I really like this feature. Although I hope that you implement the non-linear brightness curve soon, because the medium level are just too bright for me.

Anyway, I really love your Kernel :)

Keep up the great work!
[Galaxy S II Original Android Development] DobermanS:
what is format for values in file ? i see only /brightness_curve file,

what are two files gokh is talking about ? does he mean values?
[Galaxy S II Original Android Development] KcDaRookie:
@gökhan:

Just out of curiosity: Didn't you also want to make an app that will be able to change all settings your kernel offers?

I read it somewhere earlier in this post but didn't see any link to the app if it has already been released, or did you stop developing it for now?
[Galaxy S II Original Android Development] gokhanmoral:
I am developing it.

I hope that it will be ready next week.

I know that this many settings are too much for an average user. you will be able to set them in a single application soon.

the development is going slow because I am not as comfortable in eclipse as I am in vi :)
[Galaxy S II Original Android Development] :
Will try this later... Sounds interesting :)

Gokhan

The latest version of betterbatterystats supports listing of native kernel wakelocks from proc/wakelocks.

I could see slightly high "vbus_present" proc wakelock and even higher "main" kernel wakelock.

May be of any help.
[Galaxy S II Original Android Development] :
ROM issue, not kernel.
[Galaxy S II Original Android Development] System of a pWne!^:
After flashing the latest Version of this kernel, my phone (CM7 nightly) lost all GoogleApps and stuff like the BLN-Mod didn't work anymore. Had to reflash CM7 twice and reinstall the gapps. I will now stay at CM7 (default kernel).

Beta 14 working well here on miui 11 . Lower auto brightnes, backlights working great. Only thing I haven't tried yet is BT kit.

Thx Gk
[Galaxy S II Original Android Development] veyka:
vbus_present just means the charger is plugged in, nothing to worry about.

Just to check, HDMI out is not working on beta14 right?
[Galaxy S II Original Android Development] TecQuality:
not really, i've this wakelock with my device unplugged ... :)

edit: Same thing happen, so I will have to backup some apps at a time..
[Galaxy S II Original Android Development] gokhanmoral:
I think I will move ntt version to the second post :)

or maybe create another thread for ntt users. I wonder, how many people who has EU devices flashed NTT version? :)
[Galaxy S II Original Android Development] gokhanmoral:
I hope it won't reboot in titanium backup this time. if it doesn't try harder to make it reboot :)
[Galaxy S II Original Android Development] spaxx24:
It did reboot, after about 30 apps. Gonna have to backup some apps at a time to make it work
[Galaxy S II Original Android Development] gokhanmoral:
did you installed anything else other than cognition, such as additional tweaks??

I will flash it now to check if I reproduce the same problem.

and also can you check the voltage levels with setcpu?

that was a great help! I've just echoed 7 UV values to uv_mv table and my device is locked instantly.

now I will modify the kernel so that it will also parse 7 and 6 stepping uv_mv values...

Since you asked, my settings are: 100/160 with 600000/600000 and having no issues so far.

I'm still confused if this GPU underclocking and UV'ing really saves battery though...

thanks
[Galaxy S II Original Android Development] WebReaper21:
hi,

just as gokhan described in the changelog for b14, you can use the two files max_gamma and min_bl in /Sys/class/misc/brightness_curve to adapt autobrightness levels.

Please correct me if I'm wrong, but I think max_gamma defines the maximum brightness e.g. in full sunlight. It's value can be scaled from 0 to 24.

I'm not quite sure how min_bl works exactly, but from my experiments it seems that for higher values the middle three autobrightness levels become brighter. The lowest level seems to stay the same. Maybe someone else can shed a little light on this.

Also, if you change the values you have to turn the screen off and on again for them to work.

Hope this helps a bit ...
[Galaxy S II Original Android Development] bgx:
Äh, you have tryed to set to zero? But why the hell somebody want to do that? It makes no sense for me... :confused:
[Galaxy S II Original Android Development] KcDaRookie:
That's great to hear.

I would give you a helping hand but I am not familiar with Eclipse at all.

I can do a litle with C# but have a lot less experience with Java... ^^

Maybe if you publish the sourcecode you have that far people will help you with developing the tool.

But thanks for you effort with the kernel and the app :)

My S2 gets better every minute having it ^^
[Galaxy S II Original Android Development] el_tute:
bln works perfect in Checkrom 3.1.1

just flash the siyah 2.2beta6 then reboot, then flash the beta 9 or 11 or 14 or watherever beta that you want. and that all, you've got bln workin' !!
[Galaxy S II Original Android Development] cheewaca:
After try all 2.2 betas i can say that beta 9, for now, is the most powerfull of all. No lag in menu, no lag in browser and no issues with 3d apps. All others betas has more or less lag.

Hi, Im currently running galnet miui 181111 and would like to try out this rom.

Just wondering, is there an easy way to back up the default kernel so I could revert back to it should I find siyah too bleeding edge for me? Preferably without using painfully long cwm backup route. Many thanks.
[Galaxy S II Original Android Development] gokhanmoral:
extract the boot.img or zImage from the miui package and replace it with the file in tar or zip package using your favorite archiver.
[Galaxy S II Original Android Development] droidphile:
Use this attached tool (Hellcat's Kernel Companion Tool).

When you're on the kernel for which you need a backup, run this tool and select "Dump current kernel". You will have the zimage in internal sdcard. To revert back, use the same tool (Select "Flash kernel from sdcard/zimage" button) or use darkyrom tool from market.

EDIT: Gokhan beat me to it.
[Galaxy S II Original Android Development] vassalle:
Great! Thanks for the responses!
[Galaxy S II Original Android Development] GJ123:
Anybody using this kernel with OC daemon?

And if so do you have good battery life and stability?

[Galaxy S II Original Android Development] DirkTeur Velserbroncx:
I had to get used to the screen again when i walked outside so for me the lower brightness is just perfect now.

Now im still waiting for the battery improvements like it used to be in v1.8, cause i was used to having a battery drain for about 30% during 12 hrs while listening to radio or musicplayer, few calls some browsing, now with same use i get about 70% drain in 12 hrs that almost stock to me no offence cause i really like yor work,

but what happend that these apps keep the phone out of deep sleep while before ive seen the phone been a sleep almost the whole day while listening to radio or musicplayer.
[Galaxy S II Original Android Development] luizlee86:
I just did a nandroid backup (Siyah 2.2beta14 here) and my battery went from 53% (before the backup) to only 21% (after backup, just after the reboot). Is this related to the kernel?

Last days, I've been testing a lot of ROMs, so I did a lot of backups through recovery mode and I noticed nadroid backup consumes relatively a lot of battery, but 30% for only one backup?

Using CheckROM Rev 3.1.1.
[Galaxy S II Original Android Development] :
Yes it's normal. Take your battery out for few minutes to get real battery status.
[Galaxy S II Original Android Development] KcDaRookie:
Hey guys, because some may still prefer init.d scripts prior to any phone app I thought about making something like a script creator so you just have to fill in values and the script will be generated and only needs to be pushed on the phone.

So if there is any interest in it, I'll try to finish it asap.

Would be coded in C#, I know this is Windows only, maybe will work on Linux with Mono.

So, any interest?

[Galaxy S II Original Android Development] luizlee86:
By "few minutes" you really mean minutes? Not seconds? Its a serious question... :D

What does pulling the battery exactly do? Whats the difference between turning on and off the phone, rebooting, pulling out the battery for a few seconds and for a few minutes? A little off topic but also related to my problem... :p
[Galaxy S II Original Android Development] bvannier:
Great idea

Great idea !
[Galaxy S II Original Android Development] KennyLegend:
A minimum of 90s is required.It makes sure the CPU clears itself of any power so u get a more accurate reading

. Like when u charge to 100% you should take out the battery for 90s also. Its the proper way to "calibrate" the battery in the S2.

Seen OP 2nd post?
[Galaxy S II Original Android Development] gokhanmoral:
I want to share my experience with my girlfriend's phone (galaxy ace):

the battery was lasting at most 12 hours (even after battery calibration by deleting batterystats file)

I have a multipurpose li-ion charger which can provide at most 200mA.

I depleted the battery and charged the battery with that charger. it took a lot of time.

now the battery lasts 3 days.

I tried everything before that external charging. and the charger is not a special charger. it just fits to all batteries (adjustable pins for + and -gnd), a cheap ebay charger for battery.

I think variable voltage vs variable current charging makes the difference.

this is almost the third charging cycle and the battery still lasts 2+ days and she charges the battery in the phone.

I call this calibration :)
[Galaxy S II Original Android Development] :
What Kenny says is true. It's not calibration, but 'resetting' the battery/chip when those sudden drops happen.

(fka therealwells)
[Galaxy S II Original Android Development] droidphile:
No offense there for anyone.

Dev thread for this most popular kernel for most popular phone running on most popular o.s is already heavily spammed.

(Even this post of mine is under the spam category).

Making sure no more 'drop' of power goes out from the battery can not be called calibration.

[Galaxy S II Original Android Development] :
Hm... I didn't notice any change in the lowest brightness but the max_gamma parameters is working. Has anyone else figured out how to use the min_bl setting?
[Galaxy S II Original Android Development] droidphile:
Higher values for min_bl cause brightness to come down faster.

To get it lowered across all values, decrease max_gamma.

Like mentioned in the changelog, any brightness value<0 for min_bl will be considered zero gamma and anything above will be scaled between 0 and max_gamma

i flashed with Darkyrom2 tool, easy.

i was originally on cf-root, wich came with their CWM manager, is it still ok to use CWM manager with this different kernel ?

As Rom manager seems to foul up every time i go near it now.....or is there a preffered android manager to use with this one ?

thanks.
[Galaxy S II Original Android Development] v1rtu4l:
it does not have to do with a charger being boring !

it is common knowledge that slower charging will result in better battery capacity.

if you charge your phone only via usb instead of the wall charger you will get similar results, but of course it will take longer to charge...

if there wasn't this rule we all would have über-power chargers that charge the battery with higher voltage and be finished in 10 minutes ...

the wall charger are probably the best compromise between charging near top capacity and charging fast enough to let people use the device more than they charge it

cm7 samasung galaxy s2 settings menu

Hello,

on same ROM (cm7 build 114), flahsed 2.2b15 from 2.2b14, and I just recovered the device specific menu, galaxy s2 settings. Until now, and for the pas Kernels, this menue was greyed out.

I know some other users reported this issue too, so now I am sure it is a Kernel issue, as I didn't change ANYTHING between 2.2b14 et 2.2b15.

Another change : when USB connecting to computer, only ext sd card now mounts. As for me, it is best for security reasons. Access to internal sd card is not a good idea.

If this can help.

TY for your hard work and wonderfoul smooth Kernel.
[Galaxy S II Original Android Development] gokhanmoral:
Can you also put adb in the setup or package? ...to auto install of the script.
