Hello all XDA devs and users!
I've decided to run a new thread becasue recently a few users (including me) had a discussion about low free RAM available on our ICS roms and kernels (different ones i.e. Infinitum + Devil kernel, CM9 and others).
What I have found on my devices after running a couple of days without restart I end up with 40 - 50 MB of free ram with Devil XL kernel (389 MB), where the other users with similar configuration have more than 100 MB.
I know that some of you might say, this is how the Android handles the RAM and that is good when most of the memory is consumed. I would totally agree with that however when there is around 40-50 MB left, the phone starts to perform slower and starting another app result in lags.
I do not want to use any task killers because what I have read, they simply do not work well with android (see rule above).
Maybe some of you have an experience or knowledge, why on some devices there is more than 130 MB of RAM left even if there are 8 - 9 apps running (i.e. services) - after couple of days and on some others there is only 40-50 and phone lags more and more.
Reboot the phone everyday when you're having a shower.

Thx for the tip, but I do not see this as a good solution. It's hard to predict when or how often the phone gets slower due to low Ram available.

Play some good games that require higher system requirements once in a while. You'll have a lot of free ram (around 200+ cm9 nightly).

That's the proof that RAM doesn't get consumed by the android system after a day or two.
Do you use any task killers or modification to your system?

You can flash Semaphore Kernel sbm, it gives 410MB of RAM, the HD recording gets broken but i think its a good sacrifice for a good performance.

Yes I can but the point is that the more available RAM will be eventually taken by the system at the end of the day. Increasing more RAM by the kernel will not help here. Right now I have Devil with 389 so only 20 mb less than with semaphore but still more as with the default kernel.

I notice this as well. You have to either run a Rom that includes a low memory killer, e.g. aokp. Or you need to use a kernel where you can set the lmk, e.g. semaphore. I think if you don't do either of the above, the default free ram is around 45-50mb. I am using aokp with midnight kernel at the moment, with free ram set to 75 mb free.

u shuold have more ram most of the time~should be always above 60 around 100
give u best multitask also, i feel got bug but i really dun no which and what is it...
but it still ok for daily use
I got 220mb free with many process. But on miui and aokp its arround 50.

Ok i reckon the best way to improve RAM and system memory is by using this tweak.
I have around 120mb also and multitask around up to 4-5 apps without it closing.
I use ICS btw.
Ok go to google or XDA search and type supercharger, follow instructions and Wolla, U should have about 120mb of RAM all the time.
If that is to hard for you here is a simply method. Go to Play Store and type RAM manager (PRO). there is a free version but its not that good. Trust me the PRO version is way better, buy the app and use it!
It is really good!
THX guys for all concepts and advices!
After a couple of tests and research I've done so far there is one method that simply works perfect for our SGS devices.
No matter how much free RAM you push from the kernel (THX to all DEVS for BM kernels) we will not have enough free RAM for the hardware our phones have. I my opinion SAMSUNG simply f**** up here and gave not enough RAM for the phone that can act so fast and handle pretty resource hungry apps and games(
I have used 'Supercharger' script extensively when I was on GB Roms. It did pretty good job, nevertheless you always end up in the situation where more RAM is needed. In this case 'Android' (LMK) kills running or buffered apps to make new rom for the app you started.
Some time ago I have compared GS2 with GS1 against RAM. The key thing why S2 works so well is amount of RAM. Even if the system is loaded and RAM reserved for GPU and sensors the S2 has at least 500 MB FREE, which we will not have never...
SOLUTION:
The solution I have found (in fact it was not me, I simply started to using it) is SWAP. Recently one of the greatest kernel devs (DerTeufel1980) here on XDA published his kernel (Devil v0.79) with SWAP option enabled. If you create a partition or file with apps from Google Play store (like the pagefile in MS Win) you have more RAM (not physically, but still apps are being loaded into swap file).
I was doing some tests few minutes ago and got that:
- 10 tabs opened in ICS+ browser (each was unique - not Google search)
- Any.DO
- QuickAccess
- PowerAmp
- Snowstorm
And I could access every single app quicker than ever before. In fact I could not start 10 tabs in web browser not to kill launcher before or any other app I had buffered in RAM.
For those of you who are wondering if that is a good solution I can say that you should try it. If you do not like it will not use it and stay with kernel and LMK you have now.
I am happy with that so far and of course will do some more tests.
Autostarts
I use an app called Autostarts which you can purchase in google play store. What it does it stops apps from starting up on there own, you wont believe how many apps start up when they are not needed e.g - when you plug the charger in Google Mapps will start up in the background or when Wi-fi is switched on the calender will start up and run in the background, why??? i havnt got a clue but with Autostarts you can pick and choose which apps you want to start or not. I've used it for the past 8 - 12 months and i cant fault it one bit. I'm on AOKP Milestone 5 SGS at the mo and i always have between 170mb & 210mb of Ram availible because i stop uneccessary apps from starting up
i'm using ics with many running service as i can,and i never get lower than 80...gtalk,viber,Y!,any.do,gesture search,and so on...
1-first of all,try NOT to kill useful and auto restart-able apps like the ones u use sometime your widgets of course!;in my case it includes viber,facebook,any.do...
cause in every restart android lost a little of ram,and it cant recover that anymore
2-try disabling location service and force close google maps(if you've installed),it really helped me!
3-try "auto start manager" apps
4-use system tuners and tune ur ram auto kill levels.
i've tested many combinations and found 16,32,40,50,50,80 with GB 2.3.4 acting nice to me,but now i have 14,19,24,32,37,50 on ics 4.0.3 CGen.Mod and i had no problem so i didn't bother myself to test any other combination
Rebooting doesn't really help. Limiting background processes or ReChild's Advanced Task Killer as an easy solution. 400mb kernel and/or force closing/disabling apps, clearing cache if you know what you're doing.
If you're flashing CM9 nightlies every few days, you won't have too many troubles with free RAM.
Did anyone try CM9 SNAPSHOT? any reviews? Also when a new nightly comes out..is it getting better? ..in short ..devs..must be implementing new changes..

Hi
Everybody talk about changing the VM heap value, but... what is the difference after changing it? What about increase its value? And decrease it?
On the CM7 thread adamz667 post this: http://forum.xda-developers.com/showpost.php?p=15065093&postcount=4569
Anyone can confirm that?
Thanks
Increasing cm heap means that apps can use more memory which makes them run faster but then since tbey use up more mem u will have less free memory.
Sent from my Milestone using XDA App
Here you got some definition:
VM Heap Size
The heap is an area of dynamic memory allocated to programs. With a larger heap size, there is more memory for the program and the garbage collector can run more efficiently. Therefore, it is possible to get better performance by setting a larger VM heap size.
However, if you set it too high, you can run out of free memory which can trigger swapping which will degrade performance. Therefore the VM setting is a trade-off.
The optimal value will depend on the RAM on the device as well as the programs and usage patterns, therefore the optimal setting can often only be determined by the user experimentally.
Default value: varies between devices

I have tested all of them today and the best results was with 16mb.
How I was testing it?
Shadow Guardian HD is a very heavy game for MM's ram memory. So I've tested every vm heap size on one and the same level of SGHD, with the same run environment and game was most playable on 16mb (no freezes, reboots, no returns to home screen).
Really 16mb. Which rom? And how far did you get in the game?

I am using CM7rc10 (14.06.2011) I am now in 4th episode (level?) - Medusa Sanctuary.
That is very very interesting. I'm gonna have to give cm7 another chance. Maybe rc10 is a lot better than rc4 (last cm7 I tried)

i also have good performance with 16m tried most settings from extremely large to extremely small...
also png optimized most apps again and again... (which decreased the size of the apps by almost 10mb again - quite sure that it does not make much of a difference)
don't have any app locked in memory and only one homescreen with adw ex without widgets...
dunno till now i have not experienced any issues with lost sms or phone calls...
but i'm aware of that it could happen with my settings so it needs more testing, jit turned off etc. phone works like a charm since i switched from froyomod a week ago or so.

I've tried jit off and VM heat on 16MB but not get any result.
The launcher was freezing 3 or 4 times, and all games get a minimal improve: 3 seconds more until FC.
I'm testing with: Asphalt 6 and Brothers In Arms 2 (Gameloft games) and Age of Wind v2.2. All versions for MM, with people that play them on stock rom.

well as i said i do not use that memory intensive apps.
(i think my biggest apps are maps and the browser, and the browser barely goes beyond 30mb, so 2 vm's with 16mb, instead of 2 with 24. but most apps stay below 10mb so i think for my use it is a good solution)
also i debloated the rom massively and replaced most system apps with smaller ones.
cm7 performs very well with this settings, at least for me. (no redraws, no lags in ui no freezes etc...)
like i said i don't use games on my stone
edit: only genie news & weather app reloads often but i think it simply has a high priority.

That is quite interesting. On ho no I
And 20mb with balanced 3 supercharger works great. But not so well on 16mb

I've got the same with 12mb vm heap. But when I use 16mb everything works fine on CM7 and HO!NO! CM7. Maybe it depends on rom/apps you use and your own configuration.
I guess.
But I'm used to fast, smooth and lots of free ram no matter what rom I'm using

yeah 12mb is to small... experienced some errors with it too.
i have to say that for me everyhing between 16 and 32 mb seems to do not do much of a difference, but with 32mb my system uses some more RAM right after boot.
after a while it usally uses less (around 80-90mb sometimes less, sometimes more) so i normally have around 60mb free RAM, which seems to be enough.
i'm out of this discussion for now, but i have to say that i rly think ur VM Heap settings should match the apps u use.
so just try different settings.
@Zeppe
yay never experienced that, but i use only one Homescreen anyway. and ADWEX is rly memory friendly : )

Because your phone slows down when it gets below 100mb, don't bother arguing that because i know from experience that my o2x slows down and becomes choppy when the free ram goes below 100mb, because there is so much crap stored in memory.
If i need something to run ill run it and leave it there and exclude it from task manager but other wise its no use.
Its also a huge battery drain to have so many apps running that you are not using so that's a pretty stupid statement...."free ram is waste ram" lol wtf...., your battery life must be really long.
As for OP, i suggest you install a better rom, i use topigigis 1.7 rom and after killing a bunch of tasks i get up to 205mb free, altho this gets less the longer it goes without a reboot, so try rebooting and hen killing some useless tasks and see what your ram level is at.

Free ram is wasted ram. And taskkillers will only make you battery life worse if not some app is using all the cpu. The reason RAM is used by android is to keep apps preloaded, for better launch times. The built in task handler is all what is needed. My phone runs blazingly fast at all times, and I don't use a taskkiller.
yupe.. Mine is mostly below 100mb.. 70mb on average. but it's smoother than froyo with 140mb.. list of applications and files are faster to load and smoother.. so i have no complain at all.
I'm also experiencing the lower free memory in the default configuration with GB compared to Froyo. Although I'm not trying to get as much free RAM as possible (because I support the reasons given above for usage of the RAM, having apps in there doesn't mean that they're running) I'm still curious where the missing amount of memory went... Does anybody have any clue what was introduced or changed with GB that could use up about 70MB?

Yes most of the time and Yes. Some providers accept phone customization in warranty, ask yours.
If you have v20L you only have Horse Power kernel (Neoblaze seems bootloop) + Power pack 7 (mandatory, orbootloop, see dedicated threads).
If I reflash my phone using one of the original images availabe and reset it, is there any chance for the provider to detect previous flash operations?

I'd tend to relate the better battery life to the new kernel than the increased free ram. I'm on RC9 (w. PP7, no init.d-scripts) and my LGOS reaches almost two days of battery standby with ~50-60MB free RAM.

wait, this swap, what is it actually? xD
Taken from the Cyanogen wiki
Swap is, in short, virtual RAM. With swap, a small portion of the hard drive is set aside and used like RAM. The computer will attempt to keep as much information as possible in RAM until the RAM is full. At that point, the computer will begin moving inactive blocks of memory (called pages) to the hard disk, freeing up RAM for active processes. If one of the pages on the hard disk needs to be accessed again, it will be moved back into RAM, and a different inactive page in RAM will be moved onto the hard disk ('swapped'). The trade off is disks and SD cards are considerably slower than physical RAM, so when something needs to be swapped, there is a noticeable performance hit.
Unlike traditional swap, Android's Memory Manager kills inactive processes to free up memory. Android signals to the process, then the process will usually write out a small bit of specific information about its state (for example, Google Maps may write out the map view coordinates; Browser might write the URL of the page being viewed) and then the process exits. When you next access that application, it is restarted: the application is loaded from storage, and retrieves the state information that it saved when it last closed. In some applications, this makes it seem as if the application never closed at all. This is not much different from traditional swap, except that Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.

Hi Guys
I have a few question about our device RAM
1. What are you doing if your device get lagging or slow down?
- Kill App using Taks Killer to refresh your RAM?
- Just Reboot the device to reset your RAM?
- Leave your device (LOL)
- what about you? have an opinions?
My Device get slow down while browsing after >20Min, I think the reason because the RAM goes down or less than 25MB.
then my device got freeze and reboot automatically.
I hear an issue about task killer app thats bad for our system.
so I'm using app like RAM Manager or Watchdog.
2. How much RAM are you running to get stable?
My device at startup have remaining about 100~125MB RAM.
and after a few hour its goes down about <70MB.
while browsing its about <50MB. this is normal?
how about you?
I'm Running CM9 (ICS 4.0.4) right now.
Its very stable, but goes crazy after RAM run under 50MB.
I'm need your opinion guys to make RAM more batter.
Thanks for your advice.
Sorry for my bad English.
Quick reply : use a RAM/performance optimizer like adrenaline engine or another script... Uninstall others RAM manager and let me know (you find it in developing section)

If you are using AOKP, in performance settings there is low memory value, try adjusting it.
Never ever 'clear' your RAM, it will worsen your battery. Android is capable by managing the RAM by itself if it gets high. So there is no question whether the RAM meter would blow if it gets full. Read more : Article by Lifehacker

yeah, I know that. Thats way I using RAM Manager not using Task Killer App.
I tried to believe my device can control RAM it self, but in the fact after a few hour my device got freezing then reboot its self (This problem often encountered when browsing)
Thanks for the Advice guys,
I think the most problem it from our device it self, you know this is Low Device right?
so I cant expect much about the device
but I'll try to find for the best RAM tweak/setting.
Sorry about my bad English

To be honest...my device never slows down.
I suggest adjusting the ram values a little higher but not too high. Like with the visible and foreground one might freeze ur phone . Play with it.

Can you share, what app are you using?
a GB or ICS user are you?
GB are more stable than ICS
If my phone just standby is very stable, if just use for like messaging, FB, chatting or similliar like that.
but if you go browsing for >20Min, I think you can feel it.

Adjusting the RAM values?
how can I adjusting the RAM values
sorry for my bad english
Try out the V6 SuperCharger script by zeppelinrox, my phone flies with it and you can adjust min memory and other values how you want Definately give it a try!

it sounds promising
but the method will takes so long
I'll try, thanks for advice.
==================================================
Edited
oh WTH, my eyes starting throw out the tears while read that intruction.
this will takes long time. thats different while using ICS oh my .....
Trust me, it's worth it, and it does not take that much time even if you find yourself unhappy with the script
Just use swapped from android market and set swap value 250-300 and reboot you will surely.see.the.difference.

I dont know about difference, I'll test it now domcale

This thread is created to reduce off-topic posts in development section.
Use this thread to discuss my work for Mini 2. (recoveries, ROMs etc.)
Please don't make any requests and most importantly, use the search button to make sure the answer to your question/problem is already present somewhere in here.
Hi , that´s my opinion
Twice 10.1 or JB port , have a problem with battery duration (and other minor bugs)
the game play are so laggy ,and you really have a slow experience with diary use.
AOkp I think that is trustworthy to the JB use. but the same with lag .
Thanks for your work !!!! and I hope you get new roms updates.
Sorry for my english...
jelly bean requires a lot of more RAM than GB. That's why there is some lag, I suggest to use smartassv2 as CPU governor if you need performance, if you need to save battery use interactiveX.

Is it possible to fix the camera now?. Since preview problem seems to be known now?
i tried installing cm-10.1-20130629-UNOFFICIAL-jena today but get an error 7.
factory reset, cache partition and dalvik cache have been wiped, i`m using cwm 6.0.3.2.
versioncm-10.1-20130611-UNOFFICIAL-jena works without any problems.
what could i be doing wrong ?
edit: i returned to the working version and flashed it new because i finally wanted to get rid of the gapps package i installed before.
however even after flashing 0611 again gapps still seem to be on my system.
do i have to wipe anything else i`m not aware of ? the target is a cyanogen 0611 or 0629 without any gapps
do you have cwm 6.0.3.2 build 4 ?
ohh! it`s build 3 actually!
thx a lot! will give it a try at once
no problem
it worked perfectly thanks again!
the only thing i`m still facing is that gapps still seem to be on the system from a previous installation, although i wiped the 3 settings mentioned above.
is 0629 supposed to have the play store, services and other google named services? can i get rid of them somehow?
edit: solved, i had to format /system /data /cache. now gapps and other parts of the previous installations are definitely gone. happy happy!
The performance greatly depends on the game you're playing. Currently with CM10 20130629 (the NFC patch doesn't work, BTW) I have good performance with Icy Tower 2, but micro lags on Jetpack Joyride. Of course both of these games run perfectly on stock, but Icy Tower 2 has some graphical glitches not appearing on JB. But Jetpack Joyride is a lazy port from iOS and it can stutter even on better phones. But the overall performance is just fluid. Will test Vice City later to see if a lot has changed since April 2013, when I lastly tested VC on CM10.
those "micro lags" are because of RAM. I had an old PC with 256MB (!) RAM like 5-6 years ago, when I played NFSMW, I would get freezes/lags each 3-5 seconds, the loading screen took ages to load, then I put in another 512MB and everything was fine. No lags/freezes, loading screens didn't load forever etc.
On cm10 and cm9 for less ram usage i went to Developer options, scrolled to the bottom and set background processes to 1 or 0.
There are no these options on cm10.1, right? I dont know did you mean slow ramread/write or high usage with old pc example...

Ahh...the old-school NFSMW - one of my favorite games of all time.
But Android manages RAM differently than Windows, so 512MB shouldn't be a problem because it runs file on stock 2.3.6.
Looks like Jetpack Joyride stutters when there are certain sprites drawn. Seems to be some kind of GPU thing. If GTA VC runs better than this, I'll uninstall this crap.
That was just an example that RAM matter a lot in games. Temple Run 2 uses >100MB. Imaging what more demanding games require. I have about ~50-60MB free RAM when the phone is idle.
I have 210 at idle and still same lag and low fps as it is when 120 is free
Edit: cm9 has more than 100mb/s faster ram read speed than cm10, .1, aokp. And it has performance as good on 800mhz as cm10 has at 1.05ghz. Stock rom read is 500 mb/s, cm9 450, cm10 350
Sent from my GT-S6500D using xda app-developers app
Well, looks like that's the problem. I noticed that actually earlier when people were posting benchmark results, everything was higher than on stock, except for the RAM speed.
I guess there's nothing to do about it? It's all in the kernel.
Probably gpu performance depends on ram speed... So improving ram speed will improve gaming performance and overal performance of the device in cm9, cm10, cm10.1 and aokp.

thanks for your job TheWhisp CM 10.1 is awesome like you thank you very much
I don't know which games you play but I play various gba roms and hacks via my boy emulator and it is very smooth. those temple run etc. do not appeal to me. If they were then probably I would have bought a better phone. but know this. Mini 2 is not a phone to play games.
oh and a question to @TheWhisp cm10.1 or aokp. whats the difference. which one do you prefer?
You fixed camera using same liboemcamera?
