I was getting some lag on everything after 20120422. It looks like they added a third GPU clock speed. Since then i've been lagging when opening the application drawer or scrolling. Felt like i was using my nexus one again. I found it odd that not everyone had noticed the changes as i was aware immediately. iamnotkurtcobain reported using a script to change the gpu clock speeds and it worked for me.

Before 20120422 clock speeds were "166 267"

After 20120422 clock speeds were "66 166 267"

My new settings with 0 lag "133 166 267"

This of course affects battery life and the 133 step might be unnecessary but its butter smooth for me now. 100 still had some choppiness.

I would personally give up some battery life for the smoothness this phone has again.

Take gpucloc script and drop in /etc/init.d/

Set permissions to 755

Reboot

Profit?

Attached is my current battery life, i am not a heavy user so this will not represent your battery life

props to iamnotkurtcobain for the find
[Galaxy S II General] Byakuya88:
what about 80 160 267 ??? is this affects battery ??
[Galaxy S II General] nado_x:
I work in support, so I get where you're coming from. The point was that it would be interesting to see the difference in battery life with a standard set of criteria, like for instance an application designed to stress the CPU or run multiple apps in the background etc.

If nothing else to have the same criteria used build by build to actually distinguish if there is any change in battery life.

It wasn't my intention to undermine the value of these comments and it's great if these threads have helped you achieve better results. The thing is, WHAT changed those results and are the results different build by build under the same usage conditions? I'm a big advocate of standards as opposed to a lot of different set-ups. Just look at how fragmented the Android platform has become.
[Galaxy S II General] Motogeek:
Any increase to the low power state clock speed (the first number) will decrease battery life. Any decrease to the other clock speeds will decrease performance but improve battery life. It's a trade off. You'll have to find something works for you.

[Galaxy S II General] thracemerin:
The sound "bug" is hidden in a pre-compiled proprietary Samsung driver, something that can't easily be modified, the trick would be to somehow write a wrapper that controls the driver properly, StevenHarperUK took a shot at it and couldn't find an easy solution and he's responsible for many of the volume control related things in CM9, the ultimate fix would be to write a proper open source sound driver, but that's going to take a lot of work/time so I wouldn't expect a quick fix, the work around is to change all your notification and alarm sounds to silent or vibrate only while listening and it shouldn't randomly change your volume, until then just gotta deal. As far as an ETA, probably 12/24/2045.

And I have the keep wifi on during sleep as "always"... anyone else having issues?
[Galaxy S II General] Net.silb:
Thanks man,

I also noticed that there was suddenly choppiness since 20120422 build and I am now seeing a great improvement, it's now "butter smooth"! :D

And as for your question:

I made a stupid mistake of installing the siyah kernel and now my phone is being all weird at times, it's usable but weird. Forgive me for the noobish question but how I can I remove one kernel and install another? And if so can someone please provide me a link to a good kernel?

Any help would be really appreciated
[Galaxy S II General] luexi:
just reflashed back the latest nightly build and your siyah kernel will be overwrited back to stock and from there move on again.

:)
[Galaxy S II General] Duuuude:
All you have to do is re-flash the latest CM9 build and it will overwrite your kernel.

Edit: Beat to it by luexi! :)
[Galaxy S II General] furyau:
Can confirm that this is an issue.

If you have a push account, you need to disable download attachments to recent messages via WiFi. You must restart for the setting to take effect (this was my issue).

You can view the wakeups under alarms in BBS.
[Galaxy S II General] iamnotkurtcobain:
I'm glad it worked for you. Still trying to find best settings for me.. :).
[Galaxy S II General] iamnotkurtcobain:
Great isn't it? :). NOW it's smooth :)

You mean 30 mbits no mbytes
[Galaxy S II General] FRLinux:
Alright, that is a much more saner post than your original post, I get what you are saying.

I agree on the fragmentation, especially if you compare with the iPhone community.

On the battery life and benchmarking, I have been monitoring my phone with better battery stats and cpu spy for the last month pretty much, and something changed big time in that last build for me. Since I have not changed the applications nor my home wifi setup since I fixed the battery drain 2 weeks ago, I can only conclude that something changed in this latest build.

On gingerbread we just had to replace the wpa_supplicant file with a modded one and it would work perfectly. I'm not sure how different the wpa_supplicant file is in ICS but it doesn't seem that easy to enable adhoc connections like gingerbread

I noticed, that scrolling in the sms app is really laggy. Is that the same for you, or should i wipe my phone?
[Galaxy S II General] digeddydogg:
Google android.secure market issue. You need To delete or rename the folder. A think search will explain better.
[Galaxy S II General] mitky82:
10x i found the solution. Remove acount and cache from market, and log again.: )
[Galaxy S II General] digeddydogg:
Nice. Glad you found a solution. I had a similar problem when I first flash a custom GB rom aaaaages ago. Its a pain in the arse.
[Galaxy S II General] republicano:
just tried the updated rom, works great, battery life is good too,

one thing i noticed is i can make the phone stall when fiddling with the artist list in music while listening to a certain song.

was listening to david bowie - fashion, then scrolled to iron maiden, when you press it it will show you the albums, scroll so the artist is on the middle of your screen press it again to close then again to open, repeat the process a few times and it may crash.

my music is on my sd card so that maybe the issue.

happen 4 times so far. the other 3 times was just to see if i could trigger it off.
[Galaxy S II General] digeddydogg:
Try cm9 music app. Search thread for it. Something like "cm9 music apk"

Edit: here's a link.

[Galaxy S II General] Orginator:
Yep same here, got some 300+ message long conversation and scrolling thought them is definitely laggy..
[Galaxy S II General] Lechium06:
Noticed the laggy sms app too. It seems that the lagginess increases exponentially, so the problem looks like a "schlemiel the painter" issue :)
[Galaxy S II General] Phistachio:
Just asking, but is this CM9 Music App different from Music.apk already in the phone? Music.apk is very GB-ish.

EDIT : Nevermind, managed to install the CM Music.apk provided in that download, and is more ICS-ish. Thanks :)

Also, is it possible to make Play Music the default music app? When I connect my phone with Bluetooth to my car, it opens CM Music.apk instead of Play Music.

EDIT 2 : When playing music with the provided apk, it's very laggy and slow. I have to wait 2 seconds until the operation is complete, and when it's more than 2secs, it crashes.
[Galaxy S II General] GeoPrey:
No way dude :x I just installed one game from SD card and when I opened it my previous game data was still "here" so, I think, I just need to find all missing_games.apk and install them to solve the problem :confused:

Hope this will help :D
[Galaxy S II General] ludorexmundi:
Me too, since the 19/04 nightly..i've put the mms.apk of the 14/04 release in system/app e now it works..
[Galaxy S II General] digeddydogg:
Ah right. I dunno what the problem might be then. When this was in early alpha stages the stock music app was habit ducked and cm music app was working fine. Something mist have been changed from then til now. Its am old apk from Jan I think. It might have been updated since then. Google search for it. A new kne Might be on cm web page.
[Galaxy S II General] runedrune:
I have conversations with 4000 messages and they scroll perfectly.
[Galaxy S II General] ludorexmundi:
But it's a problem of some users, not only detected by me..what could be causing this?
[Galaxy S II General] Phistachio:
Yep, searched and installed already.

For those who want it : http://www.seeingpixels.org/2012/01/cyanogenmod-9-music_16.html

Also, any word on how to make Play Music the default app? Tried uninstalling the stock CM music app, but then when connected to BT, it doesn't open at all.
[Galaxy S II General] digeddydogg:
Thanks for link. Have you tried. Uninstalling all music apps and leaving play music installed then force the app to be the default player. Or check the app settings and see if you can set it that way.
[Galaxy S II General] Phistachio:
Usually, when the contacts have high-res pictures, the app loads them first, giving the laggyness, but after loading (1-2secs), it stop lagging. That's my experience at least.

---------- Post added at 11:47 AM ---------- Previous post was at 11:45 AM ----------

In bold : Yep, tried it, music app wasn't opened and didn't trasmit audio through bluetooth. I could try pushing the Play music apk to system/app.

In italic : How do I do that? In Settings -> app?

Underlined

: Nope, settings are quite limited in Play Music, no such option there.

EDIT : Apparently GMusic app already has some defaults... Never set any to start with. Uninstalled CMMusic, will try later if bluetooth still plays music or not.
[Galaxy S II General] coversnail:
I'm getting the odd random "Screen of Death" either through playing Temple Run or watching videos via MX Player. The screen gets stuck on and the the last second of sound gets rapidly repeated. I've pulled the last_kmsg but its a little weird. Right up until line 5270 when the phone reboots there are lots of mistakes with character encoding so its pretty difficult to read. All I did was copy to my sdcard and change the file name to last_kmsg.txt so that it could be copied into pastebin.

There was also the usual steep sharp battery drop which is pretty common, anyway last_kmsg is here:

http://paste.ubuntu.com/959622/

Strangely these two programs seem linked somehow. If I get the screen of death on Temple run then all its data is wiped, but also MX player forgets which videos I have previously seen as marks them as new.
[Galaxy S II General] digeddydogg:
Ah I dunno then. I can't get Google music on the British market so I can't have a go as well. Tbh, I don't use my phone for music. I just use my (very old) iPod still. Helps save my phone battery and with 120gig of music on it. Its hard to make the change. Lol. Hope it gets sorted mate.
[Galaxy S II General] Phistachio:
Here, take this. :D

Moved the app to system/app -> FC's at all time. Reinstalled and is now on data/app again. I'll test if bluetooth plays the music with Play Music or not later.

[Galaxy S II General] FreeStanler:
Thanks, but

Thanks so much for posting this. I'm on Westcrip's AOKP Resurrection Remix 1.7 - which uses CM9 features, and apparently fixes the sms problem for many users, but not for me. I can not yet post in that specific thread, please forgive me my sins, I hope another user has had the same problem still in this thread...

Now, when I send a sms, I get a notification "message not sent - touch to review the message and try again". Touching and trying again does not work, unfortunately...

I made sure to enter the SMSC number exactly, like you said. Perhaps I can try another SMSC number?

Doubt it makes any difference, but I did flash the 'classic theme' as some at the XDA Remix thread say that it could solve the sms issue. My APN setting is the automatic "Vodacom ZA_internet" setting.

Most of my friends and family are on Whatsapp etc., but naturally I need to send a sms now and again...

Thank you so much...

Well then AOKP is broken and recording uncompressed video. 30 MB/sec is insanely high (About 10 times the bitrate of most AVCHD camcorders, and far faster than any SD card I'm aware of can store). Even 30 megabits/second is excessively high for 1080p video and is purely a waste of space - not even Canon's latest camcorders (such as the HF G10) record above 24 megabits/sec - even 20 megabits/sec from a cell phone camera is a waste of space. garbage in, garbage out.

Typical Facebook sucking. Facebook has been #1 on my list of "worst power management offenders" for over a year. It's the primary reason I still keep a task killer installed.

Say... is this gpu clock setting the thing responsible for the horrible performance in games on CM9?

Minecraft for example, the controls are so lagged that it's impossible to play... setting the gpu to a higher clock can fix this? does anyone knows what clock speed the original rom uses?

[Galaxy S II General] blackomegatm:
after some testing, it appears that clock speeds have noting to do with the lag, BUT, it's still a GPU issue, as performance is not up to par with samsung roms, when running games.

Minecraft for example, runs great with fancy graphics on samsung roms, and on CM9 it runs really slow, I need to turn of fancy graphics to achieve the same performance I get on samsung roms =/

I guess this should improve overtime.

the very same line
