[Q] What lag?

I've been reading all over these forums about a lagfix that is available, but I can't figure out why I need it. My Captivate seems incredibly fast in everything it does, including reading files off of very slow cards. Is there a way I can see this supposed lag manifest itself?

Run a crapload of apps on the phone. and then see if it comes up. You can even try to install more than 50 apps and see if it comes up. Not sure why you would wanna do this though

Tried that. I started up 22 different apps, one of which was Google Earth, then opened up a HD video to play. Not so much as a hiccup. And I only have a class 2 SD card.
I guess I should be glad that I have no discernible lag to fix.

There are a couple situations I have seen like adding things to the home screen and wakeup lag. Other than that the problem sneaks up during quadrant benchmarks causing the phone to hang really bad. The lag fix works but isn't gonna make it faster in every day situations other than the one or two places it acts up.

Ohh I got it! Try to install more than 5 small apps at a time from the market. It always just hangs while they get installed
Sent from my phone so excuse the spelling errors

i barely noticed it too.. but I installed lagfix anyway lol .. as you keep using your phone more.. after you use the fix.. and revert back.. you somewhat notice differences in speed.. maybe it's just all in my head though

JAC kernel bug: using audio randomly kills phone

(I figured to post this in Android Development as it wasn't really a fit for any other forum; and made its own thread since multiple ROMs and threads use non-stock kernels.)
I ran into an issue running JAC's OC/UV kernel, as detailed at http://forum.xda-developers.com/showthread.php?t=806116 . Essentially, whenever any kind of audio was playing, whether through headphones or the speaker, local media (i.e. mp3 player) or remote (i.e., Pandora), at some point the phone would just.. die. Capacitive buttons wouldn't light up, no unlock; music would die; and basically a battery pull was required to turn the phone back on. adb logcat reports nothing - you can see the audio streaming, then the logcat shut off with the phone.
Based on the thread above (and searching the Bionix thread), it seems that a non-stock kernel does this. (There are only a couple of posts out of the thousands on Bionix's thread.) I have not tested KingKlick's kernel, only JAC's; perhaps KK doesn't suffer from this. This issue is independent of overclocking/underclocking the phone (verified by setting JAC kernel to 1000/200, then uninstalling setcpu); Voodoo lagfix (verified by disabling lagfix and running audio for about an hour); and ROM (tested using multiple versions of Franken-Twiz and Hybrid - maybe there's an inherent issue with eugene's mods, but I haven't seen any other posts.)
I suppose this thread serves as a warning/bug report for anyone that might encounter this issue if running a non-stock kernel. The best way to resolve AFAIK is to revert to a stock kernel.

Thank you for posting this! My phone had suffered from this at random times since I started using JAC's kernel. I asked about it in a couple of threads but never got a single reply. Glad to know it's not only me

I'm running the same kernal and about 20 minutes ago running pandora my phone just turned off too and had to pull the battery to restart
Sent from bionix 1.9.1 jacs oc/uv kernel

Had that issue at the Gym the other day, not even on Bionix.

I had similar issues, also with the KK Kernel, its not just JAC's kernel. You don't have to pull the battery either to get out of the freeze, you can hold the power button for several seconds and it does a hard reset.
I have found though that the KK Kernel is less likely to do it if you set your setcpu to 400 min and 1000 max before using pandora. Those settings seems to have worked for me every time..also after setting up pandora make sure to fix permissions with rom manager.
Just a little work around, try it to see if it works for you.

Actually this is a known problem since even the G1.
If you have anything like setCPU, which I do, and you set the idle or lowest speed lower then 400 Mhz the phone will more then likely freeze up when playing music or when going to idle.
I don't remember off the top of my head what causes it to do this when it goes below that certain Mhz, but Im sure I or someone here can dig the old thread up.

Man without this thread I could never get pandora to work with a custom kernal. I setcpu at 400 min and 1000 max and not a single freeze. Thanks so much for posting that tip, you made my day.

Ive had this problem to.... but it was ONLY with Jacs 1.1, I revert every ROM back to his 1.0 and have no problems. Everytime I dont, I get a phone freeze.

I was having this problem with jac's newest kernel so I went back to his first OC/UV, it is a known problem and he's working on it according to his twitter. how I got around this is I used his OC script and got rid of setcpu, from what Quadrant says I'm still running 100/1200. Hope that helps you guys

Interesting. I'll try installing JAC OC/UV/Voodoo again and see if this observation is consistent.

Yeah, I think the problem only exists when you use the OC kernel with setCPU, and setup setCPU under 400Mhz, other wise the kernel with out setCPU works just fine when it goes below 400Mhz.
Once again I don't remember why it does that but it has something to do with setCPU not being able to initialize properly after the phone goes idle and falls below 400Mhz.

Would have to agree. There's a bug somewhere. Not sure if its limited to jacs though.
Currently on masters rom kk. Only problem is pandora.

i had this problem too. kinda disappointed cause the kernels make everything run so much better. so i had to go back to using stock cause i listen to music a lot :/

There's definitely some hardware variability, because I can't recreate this bug. I listen to music all day long (MixZing, Slacker, Pandora) running 1.8 w/ JAC's OC/UV Voodoo. Never seen this.

Likewise with Jacs 1.1, had a couple other weird issues running that specific kernel too, not a single problem when I flashed back to 1.0

i get this same thing. ive had it happen with SetCPU both installed and not. right in the middle of a good song bam phone just shuts up. walk over to my toolbox and sure enough the phone is in a state of being divided by zero and only a battery pull lets it return to the world of the living. not greally a good thing when i have sevearl iphone dorks in the shop and they pop on over to my speakers and they say out of the way lets plug in a REAL phone. makes me want to scream LOL. ****ing iphone >_<
i retort with soooo when you get it out of the box....thats it right? nothing can be changed right? oh look that program sucks....what you cant make your own? ...yea...i thought so. hey look im making a call in the scrap room surrounded by 4ft thick concrete walls.... i got full bars lol. they got nothing in the empty parking lot cuz there holding it wrong LOL

I tried that though, as you can see in the thread I linked to above. Uninstalling SetCPU didn't help..

I think it's hardware.... One of the unlucky ones....

Try with a stock kernel. Jac and kk kernels do uv by default, which is like overclocking in reverse. It has the same possible stability issues.

[Q] Jerky video after Froyo update

Has anyone else experienced this?
After the Froyo update on my S, video playback has become jerky at times, to the extent that the video stops but the sound continues. This never happened before....but it returns to normal after about 10-30 seconds.
I'm playing back xvid and divx avi files, approx 700mb.
Can anyone help please!? it's getting really frustrating!

Yeah I have also experienced it. But not in all videos. In mine it is just minute that is for about a 2 seconds and it becomes normal. I am slowly coming to the conclusion that I am better off with Eclair.

My videos are fine, but MP3 playback hiccups...also apps force close all the time, even mid-call at times...Eclair was better, 2.1.1 made it bad and 2.2 has made it worse
Galaxy S flashed through Odin...unrooted..don't know if I ought to risk rooting it..any suggestions?

I have the same issue..already did a post about it.
did u guys restore apps/system using backup?? as far as I know this could be the issue.
I will do a reflash from scratch this weekend and try videos on a fresh install.

I am convinced that this is one of the issue. I had flashed a custom rom froyo and I have also flashed through kies hack JPO. In both versions of froyo, I have the same issue. I have not restored any backup or anything.

yeah I just upgraded to asian jpd via odin was on stock optus rom. Hardreset etc. lagfix fixed via z4mod rooted. Experiencing the same jerky video playback with standard divx videos. Tried another data wipe but problem persists.

Did you find any solution to the problem.. me too stuck with the same issue..for me mkv's play good, without any issues..but if its avi back comes the jerkiness..

at least i'm not the only one....
I'm still having problems and I had to give up watching somethign on the way to work as it was so bad and kept saying "cannot play this file".
I started from scratch, done a factory reset after upgrading and it hasnt fixed the problem. Also I've tried to close down all programs before watching something and even clearing the RAM, but it makes no difference.
I'm getting really annoyed with it now! Does anyone have a solution? Anyone!!?

It was so bad that I have to revert back to eclair jm1. Wonder if JPX have this issue. Any upgrade yet?

I have watched for hundreds of movies at my HTC wildfire but after yesterdays update to Froyo the video is no more smooth. The problem is so rediculous, the phone became much faster but the video playing .....Will keep searchin for solutions.

I guess it not just the galaxy hardware but other as well... maybe it froyo.

None of the players could help, but yxflash. The main problem with yxflash that together with smooth playing it produced significantly lower quality of video-rendering.
Anyway I've managed to solve the issue. The steps were:
full reinstall of official android 2.2,
hardware reset,
microSD card formatted,
the video converted with Movavi Video converter into Ipod preset or what ever your device needs. That's all.

[Q] Is this a safe setup for my Galaxy S i9000?

Hey everyone
Just a simple question; Is the following setup safe for my galaxy s i9000? What I mean is, will the phone face bootloops and other problems soon?? I am currently using it and the performance is....well lets just say unrealistic. Phone boots up and is ready go in less than 15 seconds. The reason why I am paranoid is because im coming from the stock 2.2 Froyo and the performance gain really is unbelievable.
Setup is:
- Stock XXJVT odex
- Dark Core kernel 4.1 for JVT (It has some lagfix activated or something)
- Adernaline Shot v13
- Current governor (through setCPU): Ondemand -> As recommended by Adernaline Shot thread.

I wouldn't worry to much. The performance gain from Froyo Stock to JVT is really impressive!
I had a pretty similar setup for some time at it was running very well. Some random reboots may occur as with all firmwares (Stock and cutom) I have tried before.
Also, I overclocked it to 1,3Ghz with no loss of stability.
Have fun.

Nice and clean setup. You should not face any problem.

Hello!
Just reporting back on this setup....
The performance really is amazing. Phone runs very fast, apps load and close instantly, no heating issues, browsing is incredible, and not to mention this voodoo sound thing that turned the speakers into boom boxes, and massively improved in-call sound and volume. I haven't had any random bootups yet.
However, the only grudge I have is, and hopefully u guys can help me out, that the GPS signal quality is very lame with Google Maps. Also, Google Maps is VERY laggy, sometimes impossible to use because I can't even scroll around or zoom-in/out because it goes down to like 3 fps. It is just shocking that heavy 3D games can be played for an hour without any stuttering or slowing down, yet Google's own application Google Maps barely runs.
I would really appreciate it if you guys can help me out

GPS problems?. Welcome to SGS world.

Lol ya after doing some searching I found that this is a pretty common problem. However, its not the GPS locking that is bothering me; The Google Maps app itself is VERY laggy, im currently on version 6.0.0 and it is unusable for me. Scrolling around and zooming in/out is like 2 frames per second. Do you know why that would be?

[Q] O2x performance degradation.

Got a sim free o2x and immediately upgraded it to gingerbread using LG's tool.
I have noticed that the performance degrades over time especially noticable with scrolling web pages and youtube.
From a clean boot, i fire up youtube and can watch big bug bunny in 1080p full screen and very smooth. When I come back to it a few days lastr, the same video stutters and the audio also skips. I can create this effect a lot quicker by playing something with the built in video player. After having played a video on SD card, i go back to youtube and its a stutter show again.
Has anyone else experienced anything like this using standard gingerbread on the O2x? I'v tried killing various apps and uninstalling others but nothing very scientific and the only way I can get back to normal performance if with a reboot. Any help gratefully appreciated!

Sounds to me like the ram is busy. Just try an app that cleans up the ram.

Stock kernel has bug in memory management. Solution is to flash for example Spica's kernel, latest r11-c is very very good.
Evidently that supposes to root - instal clockwork mod recovery first.

I have a problem with Spica's kernel , I think that it doesnt support netfilter (iptables) thus I cant use Droidwall, any solution?
Thanks

Instal iptables from market?
https://market.android.com/details?id=com.mgranja.iptables
Edit: the app says that iptables is already installed in kernel, not in the latest version but present. That's perhaps the problem. Only thing is to ask Spica to update to last version.

Ohhhh, i will check it later! thanks!!!

Have tried some RAM clean up apps, unfortunately it makes no difference. The amount of RAM free seemed to make no difference, i had it running smoothly with 82mb free and stuttering with over 100mb ram. If something like this was happening on my linux box I would assume something is hogging the cpu but the apps i have tried seem to indicate nothing is consuming a lot of cpu resources.
I don't want to consider reflashing with another ROM if I can avoid it. Is there anything else I could try?

Kernel problem. Read above.

Reboot your dam phone then.... pcs also get laggy when they have been on for a long time, so reboot and or flash a decent kernel.

Use stock kernel\rom from 20o

I have the same problem. After about 36 hours, the phone becomes laggy. It lags when waking up the screen, it lags in menus, etc so i have to reboot it every 36 hours or so.
Speaking of kernels and roms, i've tried them all by now. From CM7 (which i could not get along with, functionality wise) to Topogigi, spica, Thanatos, carburano, gueste and erestor.
I am now on gueste 2.1 stable SR1 and the problem persists.
After about 16 hours wake-up and the lockscreen lags, after about 24 hours scrolling becomes choppy, after 36 hours dialer, contacts and other apps start slowly and lag big time.
This is the same behaviour in all roms and kernels tried (except CM7 which is a no go for me).
L.E.:
Of course, rebooting solves the problem for the next 20 hours or so, but its quite inconvenient.
