After fixing some lags with I/O system by using filesystem LagFix I still have a Lag problem in my system and I think it's not related to Samsung.
I think this could be an Android problem.
After a fresh reboot I get 124MB of free RAM.
BUT... every day I need to reboot the phone because after 3 hours it became laggy.
Now I analysed this and read a bit about the memory management on several forums and was able to reproduce the lag 2minutes after reboot.
I just need to use much applications one after another to raise the RAM usage for every application.
When the free RAM reaches 40MB I think the system clears some pieces for using it for the app I now want to use and there is the LAG.
Is there any fix for Android not caching every activity of an application in the RAM?
Now for me Android feels like: Usage -> Full RAM -> Lag
Sorry for the new thread but after 2 hours of research I didn't find anything useful over search function.
Yea, every program should have as much ram available as their size. 2gig for program storage on sgs, so there should be the same amount of ram ;D Anyway, theres still less memory for programs on the sgs than for example in the N1. I'd say there is about 384MB of ram total on the sgs and not the 512 claimed.

Not just the RAM for the apps... there's much more...all mails from internet, all google talk conversations, the wather I checked out from internet with any widget, feels like every interaction is cached into the RAM until it reaches the 40mb mark and after that every interaction on my system is laggy... for example: opening the notification bar needs 2-3 seconds.

Heading out the door in a minute so can't comment on the rest, but I strongly disagree with that part of your statement.
As an N1 owner I've NEVER seen lag like I suffer on the SGS. Never seen the absolute FREEZE in the GUI like the SGS gets.
I'm running FroYo on the N1 now, so can't compare side-by-side to the SGS things like memory usage, but I don't think that's the issue here if you're going to use the N1 as a comparison, despite other users complaining of lag.
You might try Autokiller or the free memory manager app from the Market and see if that improves thing, they'll keep more or less memory free depending on settings. You could test how soon lag comes with default, minimal, and aggressive settings.
I never testet Froyo because everyone said, it's unstable but for me it seems like froyo has other RAM management than Eclair when you said you can't reproduce this problem.
I'm already using a task killer... I have my main apps ignored or excluded and most time there are 2 or 3 apps which will be killed after lock or time or what else.
What's the problem here... if I would use a PC with 512MB RAM and use only 10 small applications, it won't cache everything in the ram until it's full.
Hi, didn't read all the posts, but u should look into the RFS file system, which is samsung proprietery file system. It has a very bad implementation on android (i could be wrong). As for ram, the phone has 512 mb, but 128 are reserved for Gsm/data connection. Just think if you had an incoming call and all your ram was in use, u had to wait for the system to clear up some memory before being able to receive the call physiclly. That would be a long wait.
I could be wrong and sorry for the bad english.

Have you ever tried "Minfreemanager" app?
It can change the minimum available memory level in different app usage.
The device must be rooted first.
Then select "Aggressive" preset and see the result.

DAMN!!! Nice app... it does exactly what I need cleans my RAM so I'll get 120MB and after that loading of apps is much faster than starting apps with Android included RAM cleaning.
It just cleans my RAM like a reboot but without the reboot
This should be a temporary solution until someone finds a better solution or until froyo is released.
I would like to have an application like this with an autoclean option on 2 hours
Guys please,
Getting off-topic here. Here is Android Development.
Not Q&A or General.
Please post in the right section.
Here is getting too many off-topics that pose no relation to Android Development.
Too cluttered.
Thanks

Auto killer is better.Its exactly the same as minfreemanager but can be made to apply at boot.Minfree manager resets itself at boot.
I use Memory Booster Lite (free version) app to free up memory, must do that manually but it works very well, if you buy the app it free up memory automaticly.

No, wrong. The reserved ram is in the form of a ram disk, which seems to be a bit oversized. Not really sure why a ram disk is needed at all, personally.

This is the correct solution. the JF* series of firmwares have very bad default settings for killing unused apps. Use this app to set them a bit better and you shouldn't have any problems.

It does have 512 of ram, but some is partitioned off for the phone, so that you can always receive phone calls. Just about every device does this, because users would be more upset if they couldn't pick up the phone until they had closed a bundle of running programs. Don't you think that people here would have noticed earlier if the SGS physically had less ram than claimed ?
As far as the OP is concerned, sounds like you are just running too many programs at once. Its not an android problem, its user error.
Any task manager, but particularly an auto-killer will set you right, although alternatively you could try not leaving every app open when you're finished with it. You think your PC would run ok if you left one game open while you opened another ?

I wasn't comparing a N1 on FroYo to the SGS on Eclair. My comments were in regard to when I was on Eclair, which was several months...FroYo's only been available for a couple of months. What I said was since I'm on FroYo now, I can't compare side-by-side, but my experience with an N1 on Eclair was never any lag problem or GUI freezes.
Anyways, I also suggested you try Autokiller, and you missed that or misunderstood it by saying you already run a Task Killer (which is generally considered a bad idea, but I see you picked up on Autokiller after someone else suggested it. Enjoy.

Nah, all phones advertise the actual chip size in it, not the amount the system actually lets you use.

Thank you. This removes almost all lag I'm experiencing.
Hi guys thanks for your time, so this is my doubt
When i turn on my phone i have 170 MB available memory but after a while down to 70 MB sometimes to 40 MB, what should i install to have more than 100 MB free?? i already have [email protected] 256Hz #97 Kernel and 2.2.1 XXJPY firmware.
thanks

Usually this won't matter because with the Android OS, it will usually keep all the stuff you close (internet, contacts, recently accessed menus etc) cached in it's RAM as a non active application until you happen to tab into it again, thus instantly loading.
Android is also smart enough to know since the application is inactive, if it's eating your memory, it will force-close these applications to free up memory for the new applications. ie, I'm running internet, close it, and my memory is up to 280mb, then try to run AngryBirds and it will close the Internet app + others if it has to.
So... usually not an issue, but if it does become an issue you can run a service/task killer app that will handle all nonactive apps and terminate them. Or you can just clear level 1+2 ram periodically and it will reset it back to default until it starts filling with crap again.
Ok i have advanced task killer but i was reading in some topics in this forum that some guys have more than 150 MB free without using a task killer
Advanced task killer eats your battery
android doesn't need a task killer, as it kills tasks itself.. i don't know why there are so many out there they just eat up battery..
one app I would suggest is 'auto-killer' its free and I have mine set to aggressive. that's all you need to do then forget about it.. it keeps your memory from getting bogged down.
ok thanks for the tips
Hello,
This is my first thread in this forum
I bought an optimus x2 5 days ago (my first android device) and i would like to know how many free memory (RAM ?) you have.
I uninstalled some "crapware" and i currently have 89 + 142 MB free memory.
Heyyyy,
i have 162 Mb free memory with Task killer .
How did you remove the crapware?
Also how long did you do first charge for?
Ta.
My phone arrived this morning.

Not really - all you have are an application constantly conflicting with Android's automatic memorymanager and constantly using ressources trying to kill tasks and services which Android are trying to start again all over. All you are doing are making the phone run worse with less cpu free for other tasks and a higher battery use.
NEVER ever use task killers on Android 2.x and up
Its been informed and documented over and over again, but still so many wrongfully think they should install task killers.
And you have proof of this yes?
Of not using task killers ?
Seriously it's common knowledge by now, or atleast it should be for anyone having just the slightest interest in Android

OK, buT 200MB plus 385 MB used + 100MB available still do not make 1 GB!
Note have 792 available on OS, some it is user by android stock apps and services.
When I boot the phone with about 30 services and 400 apps installed I always have free about 380mb, so look the permissions to see what apps are autostarting with the boot and change them.

Please post all questions in the Q&A section
I hope you'll find answer to your questions. By the way, I'd like people to understand that free ram is UNUSED/USELESS. Our target as users and/or developers is to achieve the "enough ram for every process and app" objective. That is, we absolutely want that every bit of ram is used to make the whole system faster and readier. If you have services you need ready to be executed in ram, and you have ram for all of them, you have the best resources / results ratio. If you have 1GB of free ram and every app you need must be raised from scratch, you're not using your resources the optimal way. My 2c - maybe ot?
Good luck with your findings, anyway.

Thanks for your message. However, I read in many forum messages that too many apps in the RAM slow down the display reaction, which I found myself too.
However, I've just done the 10-second soft reset and found my RAM usage went down to 187MB used and 530MB available for services. Also found in applications management RAM capacity info: 372MB used out of 800MB. I suppose difference comes from the fact that the first capacity info relates to the space available for applications and the second used capacity includes applications AND System.
But in this case it means the Note has 800MB and not 1GB of RAM as advertised!
It has 1GB as stated. 200 MB are used by the OS. 800+200=1000.

But why the active applications list on the bottom says 187MB used and 530MB available RAM , while the task manager/RAM management shows 372 MB used space out of 800MB??
This is what confuses me: in one place it is shown that 178MB is used and in another 372 MB used !???
Please clarify !

The difference is because the active applications list in running services does not include the amount of RAM used to cache apps. You can press option key while in running services, there should be an option called "show cached processes".
If you add the amount of RAM used for both cached and running apps in running services, the total should be similar as the amount of RAM used in Samsung task manager.
This is because Android considers cached apps as free memory. They are background processes that are not visible or directly affect our use of the device and can be killed to free up memory to run service processes (i.e. user launched apps).
The cached processes basically are a list of recently used apps stores in reverse order, i.e. the least recently used app is at top of the list and most recently used app is at the bottom of the list. This way if the phone is running out of memory, it will start to kill off app at top of the list, so the app that was last used will be the last one to be killed.
The idea of cached processes is to improve the start-up time of an app the next time the user needs to run it.
P.S. I'm not an expert in Android operating system, this is just my general understanding of how Android RAM management processes.
Thank you very, very much for clarification. Now everything becomes clear and consistent !
Best regards,
Radi

When I check running applications tab insettings, I can see total RAM as 800 MB. Thanks for clarifying. I had the same doubt. But is there any way to check how much RAM is allocated to GPU using any android setting? I am keen to know this.

Hey there, this problem might have been discussed before but I wasn't able to find it, so the problem is with ram usasage, I once went to the apps in settings and on the running apps I always see 250mb+ ram used by something, then I killed all the apps, but that just made a dliference of 50mb ram, It's real anoying because when I want to switch between apps it's slow and when I turn a browser back on after using aother app the page realoads which I guess wpuldn't happen with 300 mb ram, does anyone know the reason for this, I am currently running cm10.1.
Thanks!

Free RAM is useless. It just sits there sucking up power and being available in case you need it. It's pretty much a waste to have 300 MB of RAM and then only use 100 MB. Instead you should try to keep your RAM full at all times with the things you are likely to need in the near future. For example, if your phone is currently only using 20% of your RAM but already caches the browser in case you'll use it soon it will be faster to load the browser. If you decide to use the music player on the other hand the cached browser can be overwritten with the music player without requiring any additional time, so no harm is done.
Modern systems don't have "free" and "in use" RAM, they have "free" (wasted space), "in use" and "cached". You shouldn't look at the amount of free RAM but rather the amount of actually used RAM is a better indicator.
The reason you only gain 50 MB when you kill all apps is because only 50 MB will be actually in use by apps and all remaining unused space is used for caching things. If your phone is slow, this is not the cause of it. You may just have a slow phone or the ROM might be slow for some (other) reason.

yeah only 50mb is used to keep the apps running, but it probably takes up a whole lot more when using the apps, and this is a problem for me that it is slow to change between apps, and when I do change between the for example if I wanna text some one back while using a browser, once i turn the browser back on it restarts the page, and that didn't happen in my zte blade, unless I had some more apps running.
I wanna know what is using those 250+mb of ram!

see exchange service,any svn services n keep track of system usage. normally 100mb+ will be taken for ui, framework...etc.
but. eventhough u keep track of it,then slaughter it, it will come back to life n running, so i wouldnt recommend slaughtering system usage.
switching between app normally slow for full or stock rom. try find some debloated rom. it will be suitable for u if u wanna more free ram rather than liquidity.

I also observed some sluggishness after some time of usage. Sometimes the phone got totally unresponsive, not catching any push events (from buttons or screen), so that I couldn't even wake it after the screen timeout. I had to wait even few minutes before it was alive again.
Google Chrome was the most ram-eating app as far as I know.
Sometimes the best method is just restart your phone from time to time or even make a wipe - this is normal for all low-end android phones as they get sluggish after some time.

But I don't want to buy a new phone...
The lack of memory is noticeable when I run Waze or maps . It just opens for a couple of minutes and closes by itself or rather hangs the entire device.
What should I do? Go for the CM10.1 stable, try a different ROM (i.e. Slim). Change kernels?
nope, waze doesnt use that much ram, try to fix permission first n clear cache in recovery
n try to use other kernel, mine ok with multitask, rather heavy with online games n hearing mp3 n receiving whatsapp, line n we chat at da same time
n try greenify app to control app thats always running.

Just try a other rom or kernel you would be amazed how lets say a change of kernel can speed things up. The point is everyone uses their phone differently different apps and things so you need to find the rom that suits you mostly.
