Well guys, i always listen about the ram used in android is different than windows..
My first question is, why RAM is like 90% used, the phone become slower???
My second question is, Why 99% of apps are always started with phone, when enter in Applications section, and see Running apps, you see millions of apps, or when you enter like, Calculator or Torch or another app details it appears Stop.. WHEN I STARTED IT?
Im now user of Galaxy S Duos, when i have Motorola Atrix using a custom rom named "Neutrino" my ram, after flash it was 80~90 and here in Galaxy S Duos is 390~500 and the max is 685mb so so, than when press clean RAM, it closes a certain number of processes but only 50mb ram max it decreases... Why?? And what can i do about that??
Thanks!!!!

First, the Linux system (as Android is based upon) always try to make use of all available RAM. Having unallocated RAM is wasteful, so all RAM not used for apps, is allocated for caches etc, making your device not slower, but faster. When this memory is needed for better purposes such as apps, it is dynamically reassigned.
The other question I'm quite don't get, please clarify it and I'll give it a try. But Android do start and stop apps as it see fit, unnoticed by the user. This is the Android way of resource management, instead of paging/swapping. I.e. Android "swaps" entire apps, not RAM. As a developer, you have to know this, making your app able to handle a restart as transparent to the user as possible.

Yes, i know about that but i'm crazy because when my phone is slower i see the ram and it has apparently 500mb used from 680mb total... And i click on Clean, it closes like 20 apps and clean 100~mb aprox. of ram, and the phone becomes faster... That is my question, i know about linux... in galaxy s duos have an option to kill until number of processes you would... But didnt work i think because, i put max to 3 processes but even when i close the apps with back button, like facebook, instagram and another without home button, it stills on memory, taking the phone slower
But thanks for trying help me :victory:

It is because different task killer have different security policy, which allow them to show the system apps or not. So, in the lower security policy, you can see more running apps and gain more memory after kill them
i do have a question. why are you using a task killer?
I'm not having a dig at people that use them, but more trying to educate people that they are not required
"free memory" is not indicative of a healthy system in linux based machines.
please remember the way in which linux based OS's (which Android is) handles memory. Basically, if you have a heap of free memory it is simply wasted, the OS is not running any more efficiently. It is actually slower.
Here is a quick overview. Written for the desktop computer perspective, but translates over to a mobile phone OS quite well.
"Traditional Unix tools like 'top' often report a surprisingly small amount of free memory after a system has been running for a while. For instance, after about 3 hours of uptime, the machine I'm writing this on reports under 60 MB of free memory, even though I have 512 MB of RAM on the system. Where does it all go?
The biggest place it's being used is in the disk cache, which is currently over 290 MB. This is reported by top as "cached". Cached memory is essentially free, in that it can be replaced quickly if a running (or newly starting) program needs the memory.
The reason Linux uses so much memory for disk cache is because the RAM is wasted if it isn't used. Keeping the cache means that if something needs the same data again, there's a good chance it will still be in the cache in memory. Fetching the information from there is around 1,000 times quicker than getting it from the hard disk. If it's not found in the cache, the hard disk needs to be read anyway, but in that case nothing has been lost in time."

yes and yes!
if your phone requires the resources, it will kill tasks that are no longer required. its all automatic. let it do it itself and you will have a much happier phone
AND better battery life, because the android OS is not continually restarting processes that your task killer deems unnecessary. I would trust the actual OS over a 3rd party app. It is designed that way for a reason (see my previous post).

The idea is absolutely right if memory is being used for apps you are likely to open frequently. ATK allows you to unselect the apps you want to keep running. That way you can unselect the ones you use the most and then use the widget to kill everything else.
I notice when I press the home screen many apps don't kill them selfs and after a while I have loads of apps running and the system starts to lag, specially when I try to run something else.
There are advantages in both approaches and I find a mixed combination (available with ATK) makes it best, although the user need to use some common sense to do it right. Killing everything means the system will be more responsive but regularly used apps will take longer to start up. Not killing means the apps you use a lot "startup" faster when you use them repeatedly (as in fact they never stop running) but after a bit the system will lag when using other apps and may need to use pagefile/swap to atone for the lack of free RAM. That causes page faults which make the system even slower.
The iphone developers aren't complete idiots for killing every app. They have a priority for system responsiveness and they did achieve it at the cost of background running apps. I like the possibility to choose what I want to keep running and kill the apps I'm not likely to use again and it's one of the reasons I picked android.
A little Offtopic to both ifanboys and ihaters:
I never owned any apple product as I think of them as over priced. That said I think the iphone has great merit and I doubt very much we would have Android if the iphone didn't pave the way. Besides I jailbreak my brother's 3G and made it multitask enabled. Now it runs apps in background and there is little diference between it and my android. Except for the extra 200€ it cost, the lower hardware specs and expensive service provider contract my brother pays for a mandatory 24 months, while my X10 cost ~65% initially and came free of any contract.

Thats what I and others have found, which is why some people choose to use one, myself included. Someone posted a link to an article last week with similar information posted here about the OS handling itself, but the comments section of the article were full of comments similar to what pco and myself have said, so it's all down to personal preference whether or not you choose to use one.
I did use a task killer for a while, then stopped. Personally my phone is better without. I have nothing except weather that updates automatically, I do it manually when I need it.
It is one of those things, just like on a laptop, everyone has different configurations and usage patterns that results will vary.

The browser for instance doesn't. Same with many other. I think it's up to each individual developer to program that behavior for his app.
I got Visual task switcher and I notice lots of apps just stay running forever.
Task killer caused probs for me. A daily switch off doesnt hurt, but have run mine for 7 days and been ok. Even a bberry cant do that!

Guys, don't use home button to exit apps.
Will just send them in background.
Use the back button... this won't exit (most of) the apps but will put them in a "sleep" state so, next time when you will use it, it will load faster.
So, again, home button will put the app in background, still running.
Test it with an audio player for ex.
Or a browser... send it in background with home button and the player will still play or the browser will still have that page loaded.
With back button, after all views are "closed" the app will close too (well, put in sleep state).
I use ATK only to kill the apps i use once in a while ... the rest of the stuff, is always in memory.
My X10 has usually about 25Mb free
Actually I used ATK to kill application that need to connect to internet, and in my case there is extra charge payment. But after i used ATK I don't notice that the battery live is longer. So I ever ask someone in my thread about after ATK kill applications and so forth....
And somebody told me to quit using ATK and now I realize that the battery last longer than before.
But one thing still bother me is:
Setting - Wireless control - mobile network - mms & data (no checklist)
means: I can not access internet and receive or send mms either.
Actually I only need MMS, not internet.
May be somebody can help me solve this problem.
Thanks.
But my conclusion:
NO NEED ADVANCE TASK KILLER.
After I uninstall ATK, my phone still running smooth and the battery last longer.
May be we just need best Cache cleaner. But I still trying some of that.
@pco.vaz
I don't want to be mean, but you are wrong.
Even those iOS versions that are not multitasking enabled keep apps in memory. Leaving an app on an iPhone resets its UI state and halts its processes, but parts of the app are left in the memory. You can see the difference in loading speed if you decide to reopen it.
There were apps that could show memory usage and clean it on the App Store, but Apple removed them. You can still get them through Cydia and see for yourself how memory management on iTouch devices actually works. Basically the iPhone goes as low as 3-4 megs of free memory and handles it in smiliar way as Android.
On both Android and iOS, apps that are in background are paused after a while and do not use processor cycles. Memory they keep occupying is overwritten if needed by another process.
I do not recommend using task killer to people who do not know what they are doing exactly. Killing even simple processes often causes phone instability and drains battery faster, as others have already said.
If you feel your phone is stalled, perform a simple reboot. There are apps that run in background (in most cases you are warned about this) or are poorly coded that could cause this behavior. Other than that, inbuilt application manager is able to force close apps pretty well, if you need to kill a single app causing problems

I would recommend a 3rd party launcher like ADW Launcher on Android market very light weight, also a app like memory booster which frees RAM. Their are no such mods to change the file system usage as changing the amount of RAM the system needs could result in a unstable device. I have a Galaxy wifi 5.0 with 512mb RAM and the 200mb left is enough for me without lag etc. hope this helps
I recommend using Advanced Task Killer. It has a very easy interface, and frees up ram quickly.
What does it say for ram on the player.... I have seen 377... and 345.
I have 345 and Im pretty pissed about it.
I have 342mb of RAM available. But I heard that around 100+ mb are dedicated to the gpu on the galaxy s phone, and the galaxy player has the same hardware so should be the same. So I think it still has 512mb of ram, but just 342 is usable by Android.
Have a look at the output of dmesg (e.g. run the following in a terminal and copy the resultant file to your PC to view: dmesg > dmesg_output.txt) and it tells you how much memory you have and how much has been set aside. Note you will probably want to reboot before you do this as otherwise the interesting messages have scrolled out of the kernel message buffer.
I've been using an app called Fast Reboot Pro. It appears to simply close processes that are running in the background. It then shows you how much memory was was freed. I hit every so often and especially when things appear to lag. Seem to work pretty well.

Gingerbread/Samsung has it's own task manager which in turn has it's own widget which does this. No need to install an app for this
I to use fast reboot, find it much more effective than what the player comes with. I also use ram manager pro witch is a very good tool to set different ram profiles, I like "balance (more free memory)" the best. I first select my profile, then I run fast reboot, very effective! The more you run fast reboot, the more memory it frees up, witch is great for big games like asphalt 6. Also, I use zeam launcher, very lightweight, perhaps the lightest, but still a great improvement over touchwiz. Another thing, NO LIVE WALLPAPERS is an absolute necessary! These things eat WAY more ram than they say on taskmanager. THEY CAN EAT 50+ MB OF RAM!! Also, services like widgetlockscreen and such will eat your ram. If you want to play a heavy game, go to running services and kill as many as you can, you can also clear cached apps by hitting the menu button in running services. Hope these tips help you to make the most of our small supply of ram!
Hmm, after more testing, it would appear that wifi burns around 25mb of ram when on! So, if your really short on ram, just turn on airplane mode to kill all antennas. I just played modern combat 3 with 25mb free ram throughout the whole level I had 190mb free originally, that game sure eats the stuff :s The CPU rides at 1000mhz through the whole game, lol, could always use some more of that stuff! That's what oc is for

Jesus. There's a huge panic now because the variant has 2 gigs of ram...
http://www.androidcentral.com/ram-what-it-how-its-used-and-why-you-shouldnt-care
You actually have more free, but the android has a lot of it saved for caching, etc. For example, Facebook takes 40 mb, but when I open it only like 5 or 10 mb of the ram shown as "available" is taken away because parts of it are actually open already.
But yes, if you root it, and a developer adjusts the Minfree to a large amount you will have more free but your phone will probably be slower.
Folks need to keep in mind, that keeping RAM free as you would with a Windows based OS, is NOT ideal in Android. Android uses RAM completely differently and it is perfectly okay for your phone to make use of RAM, even for apps you are not currently using.
There's a fair amount of documentation out there about this - do some Google-fu to deep dive further.
Actually I ask because when I was trying to send a picture in whatsapp it kept sayin "try again" but when I closed all tasks in multitask the picture did send. So I'm guessing it is a ram problem.
Also take it easy on Mr. This is my first android phone, I've been using iphone since the 3g and don't know nothing about android..... yet

You don't really want to much free ram. If there is to much free ram it means apps are not going in to cache witch will mean really slow app loading times. 200-300mb free is ample for new apps to run, if the OS needs more then its auto memory management will come in to play to free up more if needed, android is a very smart peace of kit

if anyone were to choose pre-caching order for faster load times ( usually just by seconds than non-pre-cached) to no random force closes because there is more free memory, they would chose more free memory.
but since the experts have already said android memory doesn't work the same way like windows does, then the best would be a balance between cache and free memory. right? right. that's where official updates and dev fixes come in.
Hi pls is their anyone who could fix the high ram usage a mod or something?
Sent from my GT-I9300 using xda app-developers app
What do you exactly think ram is, or "high ram usage"?
What are you expecting to be fixed?
This phone has plenty of ram, stop looking at the numbers and thinking your too high, don't listen to anyone that tells you that you need to kill tasks to make the phone better, they are all wrong!
Android works on a linux kernel, its not like windows and does not slow down (noticeably) when you multi-task, it manages its ram usage, it caches processes to save you time and battery next time. When it's ram is truly full (which I doubt yours ever is) it kills it's own apps.
So in summary unless android is closing all your apps when your trying to use them, stop worrying about ram!
/rant
Please everyone stop saying that Windows does not use the RAM for Cache.
Just because it doesn't show the values in Task Manager doesn't mean it isn't doing so. The Resource Monitor tells otherwise.
port76, if you're rooted you can throw out all the apps that you do not use (e.g. the whole Samsung-Cloud stuff, Samsung Accounts, AllShare, ...) which will give you several MB more of RAM available for caching.
For the rest, refer to this: http://www.linuxatemyram.com/

I guess it's due to low memory killer.
when i start the aplication and then press home to leave it on, after 2-3 minutes when i enter the aplication again to continue, the phone it loads from the begining like i started again
I would say this is normal, Android kicks Apps that you don`t use for some time automatically out of memory, so that you always have enough Ram left to use your current active application. Especially when you open Apps that need a lot of Ram. Android automatically will kick out Apps that are in the background except if they have an icon in the notification centre (That`s why Apps that are supposed to run in the background all have an icon in the notification area). If you want to keep Apps in memory check out the Xposed framework
http://forum.xda-developers.com/showthread.php?t=2130044
I need root for this,right ?
Of course you do. You should also look at custom roms, as they're much more optimized, and that includes also more free ram. Don't expect awesome performance on pure stock rom .
So this problem os not only for my phonw ...?
Android is designed that way to take up almost all Ram available on the device because unused Ram is wasted Ram and when you are running out of memory Android begins to kick out applications that are in the background. That will happen with every Android phone. Maybe in the future when we reach 4 gb of Ram multitasking will have a Windows like feeling where you can leave a application in the background for hours and come back to it and use it as you left it.
And like JustArchi said, yes you need Root for the Xposed framework to work because it changes some stuff in some system files.
On my old wildfire s i never happenes this ... and ny free ram is around 100 mb.is ok?or is a problem with my phone?sorry for noob questios ...
Your old wildfire S was based on Android 2.x I suppose, also with lower resolution, performance etc.
It's like comparing windows 95 to windows 7, windows 95 uses less, guess why.
Actually I have about 300 free ram + zram, so it's about 500 I'd say. And yes I have a lot of apps in the background, including one game .

100 mb free RAM is normal. With Android you don't need to worry about RAM ever! The Ram management on Android is very good and it knows exactly when you need more free Ram so it will then kick out applications that are currently in the background.

Nope without Root at least to my knowledge you can't do anything and with Root Xposed Framework is the only way I know of to keep certain Apps in memory.
On the other hand I can't see any disadvantage of rooting a phone, you can always get back to pure stock.
