[Q] Why no ones talk about the lag cause by Insufficient memory

I notice the phone start lagging when there are less than 100Meg of available RAM on both 2.1 or 2.2 SGS.
Questions....
1. How do i make sure there will always be min 130 available when not in use?
I'm currently using Froyo Task Manager, ATK and SystemPanel together to make that happen manually. A better suggestion or use of them will be appreciated.
I also tried MemoryPlus and Taskkiller (The red android logo)
2. There are so many background service running some of them start with com.samsung.... (what are these?) do we need them?
3. Why some Apps always run without us telling them to run, or ask us to give them to permission to run on background at will?

ATK
In ATK in settings you have auto kill level, which is disabled on default.

I'm using JPC, ATK autokill will not able to kill at a system level like SystemPanel, so after a day of active use, the memory will still continue to reduce as some of the background service start consuming more and more memory or run more background process. E.g. Touchwiz from 17 Meg to 25 Meg.
So at the start with ATK, i will have 130Meg, after a day of active use i left with 80Meg. With Apps killed.

I use autokiller set to aggressive. memory left 152mb

Cool, does that remain for few days? How often do you restart your phone?

free memory is bad memory!
why don't let android do it's job?! this ist linux with a clever memory management, not windows 95!!! deinstall all auto task killer android is handling the memory very well. it uses all it can get and if it's not enough it kills old uses apps from it. why have free memory, there is absolutely no reson for that! ram is fast, let the often used apps be there not on slow sd or nand!

QFT!
What is the point of having memory if it is constantly empty?
Think about it this way...If you had five friends at your house and you have five chairs, do you make 2 or 3 of your friends stand so there is always empty space or do you let everyone sit down and worry about something worthwhile?

True, upto a certain point... I don't think you need to have at least 100 or 150 mb free but it DOES seem to help to not let it get down to like 30mb...

For me:
-JM7
-animations off
-voodoo lag fix
-minfree manager set to preset agressive.
minfree manager customizes the android memory management system.
I love it this way, No lags when starting the Phone (DIALER) or anything else. The dialer annoys me the must, this must be lag free, if i want to dial i want to dial right away.

Btw, I think you have made some wrong assumptions about the Android memory management system, as mentioned, unused ram is wasted ram.

Agreed but I have never seen my Galaxy with free memory that low and I don't use a task killer. Of course I don't often have more than 3 or 4 apps running at the same time

This is not about letting ram do nothing.you surely don't wasn't your ram get used up by programs you don't want while you had no hand in this.All those services running I don't want.badly written programs that are hanging out in memory instead of closing.at least in symbian an app closed when you exited.

Why would you have 100MB free ? Do you have any application that needs 100MB to run ?! The android system already has enough memory to run so even if you could have 200MB of free memory you phone wouldn't run any faster you would just be able to lauch around 20 apps at the same time.

Linux however isn’t generally affected by this. While I admit that I don’t know the architecture and reason for this… linux will run the same regardless of if you have 20mb free memory or 200mb.

Dunno, I just noticed that one time my phone was VERY sluggish and memory free was around 20mb or so. Cleaning it up did seem to help (unless one of the programs killed was causing the lag of course).
Ah well... Whatever people choose right?

You guys can argue all you want that free RAM is a waste of RAM....
But it is a fact that the SGS runs much slower when the free RAM is low. This is the experience of all the SGS'es I have tried and my own as well. At least this is the case when running 2.1. I have not tested anyone with 2.2 yet.

It s starts to lag when memory is below 40 mb. So when it s low and you start an application it starts to lag. I set it to 50-55-60 and got hardly any lag. No need to keep so much free ram

Which ROM are you using? as the low memory killer level for background apps is set at 40M which means you should have 40M free all the time or it will start killing background apps. This is also why task killers are useless, free ram is wasted ram for android.
I never had the experience that more free RAM is faster, perhaps with the stock rom but JC and upwards are all good by default. Animations off + Oneclick lagfix (or another) and the phone stays totally lag free.
Being an android user for 1,5 years now i'm very confident Taskkillers are useless except when an app is stuck. I've had periods where I used them allot but the phone only gets slower as the killed apps have to be loaded into the memory again.

Provided you are not expecting anymore friends. The problem happens if all your 5 friends are happily seated and along comes 2 more friends a-visiting. So you have to now move 2 inactive (for want of a better word) friends out of the seats so that you can accommodate the 2 new ones. This takes time. So why not move these friends out as soon as they become inactive so that the space is readily available when someone comes calling?

Try to have a read about garbage collector before argueing about free memory.
The more you try to have a large amount of memory, the more you will need major GC (and during major GC all activity is frozen).
If you let the system manage memory, it does minor GC as needed when it reaches min memory waterline (seems to be 50Mo on SGS).
Let the system do its job.
Get rid of task killer.

I completely disagree. OK, it is better to use memory, but the android memory management is extremely inefficient since it does not know which foreground and background processes are important to the user and which are not, even though it tries to figure that out. Since the Galaxy S does not allow the system to use the full 512MB of memory, this can be a critical factor. And the Galaxy S definitely lags massively when less then 70 or so MB of free RAM is available this is definitely a fact.
The biggest problem is that you cannot manually close apps and only have multitasking access to the last 6 apps used. If you use 7 apps simultaneously, the 1st app still consumes memory but you cannot even switch back to it. And there are so many useless background processes, starting up over and over again and consuming hundreds of MB memory if they are not killed in regular fashion.
Who needs gesture search, amazon mp3, layar, and all the samsung crap running in the background all the time. If you only have 10 such applications and each of them only consumes 15MB of ram, 150MB are wasted for nothing.
Every second market application registers itself as autostart on every boot, so to use a autostart manager is also mandatory.
Since everybody can easily develop for Android the application quality and resource efficiency is not always perfect. So in my opinion Android needs a task manager, this is why even Samsung integrates such a application.
Using a well configured ATK (set to ignore system applications, widgets and apps frequently used for multitasking and killing every else on screen off) and autokiller (strict setting) in addition to Autostart Manager (had to remove 40!!! useless apps from automatic startup) and lagfix, the SGS runs perfectly smooth.

[Q] Save RAM

Hey Guys,
is there a way to save RAM ?
I'm using this Rom & I have only 79Mb free of RAM.
I tried zeppelinrox V6 SuperCharger
But it doesn't work.
so does anybody know an other way ?
Hmm and a question,is tehre a way to disable Sense 3.0 Task-manager ? cause maybe V6 SuperCharger doesn't work,cause of task-manager(maybe he kills it)
JuLiian

no need to think about the ram handling. when its going to be full (mean few MB), android will free some ram

One thing you should know about Android is that it takes care of itself when it comes to freeing RAM and all that. Using task killers and RAM optimizers can do more harm than be helpful. I wouldn't worry about not having much RAM available since Android frees RAM for you when it gets a little low. Maybe check for apps running in the background.

Two excellent guides which support meaples opinion:

Technically, it's hard to tell the difference performance-wise. Android does it's own memory management, but also it won't hurt anyone if you try RAM tweaks and see the result for yourself.

remove facebook, yahoo, and all other apps that runs on the background,
even if you have v6, the apps still runs in the memory
no matter what ram tweak you do if you have background hog memory apps and due to the limitation of our device you shall fail

I did not quite get that you said there, but I didin't encounter a single problem due to low RAM. Of course it can be because I don't usually run a lot of apps at once.

if you are much conscious about ram then never use and go product they are the hogger beast
check every app's ram consumption then you their alternative with less ram consumption
if you love ics keyboard, then there are 2, one uses about 10 mb and other uses about 20 mb

Well, thats true, but the RAM is meant to be cached (fully used) for quickly launching the desired application.

Best way to optimize RAM for starters is to monitor your background, cached and running processes well. First, freeze stock background running bloatware using TB. Mainly DRM content (some say it messes with ringtones and stuff but I never experienced that), wsynclmps, syncmIDs, maps (unfreeze it only when needede), software update(this really doesnt help and is waste of RAM+space), pico TTS , TTS service(these two are for voice to text conversion and are literally not much used), samsung account(is waste compared to play store), two email ones (use gmail app these dont help much), social hub , samsung push service.Choose adrenaline engine if you want multi tasking and v6 if you want more free ram.You can mix both of them but its risky and needs some scripting skills to remove the conflicts they make and highly NOT recommended.

completely agree with this one. less ram is not alway a good news in android system since it has unique RAM management. for quick acces and less RAM r/w some of app is stored in RAM's cache. SGY's default ram setting is already good enough for multitasking and gaming option. if you want a better performance in your device you don't need lesser RAM. instead of it you need a better memory and app management.

[Q] RAM usage.

Hello guys,I'm using BioHazard_W v.4 ROM, and the RAM usage of it's pretty high, how to lower the ram usage on it?
It's always over 240mb from 350, I wan't to tweak that RAM usage to 150-200 normaly, any advice on that?

240 MB used out of 350 MB ... that means 110 MB free.
That's a respectable number.
Now let me tell you one interesting thing about Linux : free RAM is useless RAM.
Whenever possible, Linux will leave you with as low free RAM as possible, and use the rest of the RAM for caching. This will not only make the system goes faster, but -- in case of portable devices -- reduce power usage as most of the most-often used data is kept in memory, saving the device from having to access a storage media (which consumes more power than accessing the RAM).
So... if your system is not suffering from endless lags and redraws... just ignore the RAM usage.

Btw, my phone had 40mb of RAM free right now when I checked, and I can't multitask successful, when I minimize something and open something else, then, when I decide to open the previous app, it reloads again, and I just wan't it to be on RAM and minimized.
Any suggestions how to make the multitaskin way better?

In that case, try cutting down on apps that continuously run in the background.
In my phone, apps that run in the background are : Google+, Avast!, Pulse (update every 3 hours), Tasks+, Widgetsoid, and CPU Tuner. All other apps I prevent from starting using AutoStarts.

Can you lower the ram usage?

Hi there,
I have the ZF2 with 4GB of ram. After a couple of days of usage, it seems impossible to lower the ram usage below 1.8GB even when I clear the cache of all apps.
However, when I restart the device, my ram usage is below 1GB.
I have uninstall or disabled every app I could without rooting. & I don't want to root now.
Nonetheless, I would like to keep the ram usage of my device as low as possible (2GB of ram use seems a lot to me, especially when I have one or two apps open)
Did you find a tricks or ways to keep 2gb or more ram free at all time ?
Thank you.

Simply, there is no clear way and those numbers are normal. The best memory management is with native linux, not yet available on zenfone 2.

What's the point of always having 2gb of free ram? RAM is completely useless if you aren't using it.

It's not a question of useful or useless. It's a question of is it possible and if yes, how.

Yes, keep the phone in deep sleep with all apps closed and disable everything in autostart , better yet, you can just power off the device
p.s: not even custom roms will run that low, I had cm12.1 with lg g3 3gb ram, I disabled basically everything and phone will still boot with at max 2gb free ram, maybe 2.2gb if you start killing launcher and sytem apps lol
4Gb ram with 2.2-3Gb free Ram is plenty for a cellphone. Its even plenty for a desktop unless you run hard core 3d games like crysis.
The lowest I have seen is 150Mb/1Gb usage with Nexus 7 v1 tablet yet it was hell slow. Note that the more Ram you have, the more the system will use it and cache in it. This will increase apps loading speed since they are directly loaded from Ram vs local storage.
I would love to have an app that lets you select what to cache in Ram, e.g. large high-resolution PDFs that take forever to open and load :crying: I have 300-800Mb PDFs that will take 1 min just to open.

Indeed, an option to decide what to cache would be great.
Can we expect less usage and caching with the 5.1 update or with a custom Rom?
