My new Samsung Galaxy S 4G has, to my understanding 1G ROM for system use, 512MB RAM for apps to run in, and an 8GB SD Card for storage.
I'm not understanding something about the setup though. The main question is I go to Task Manager, then RAM, and I usually am using about 250mb -- out of 323MB. 323mb?? Where the hell is the rest of my RAM?
Also when I install an app that can't install to the SD card for whatever reason, where the hell is it going? into my 512RAM? Into my ROM? When I click the Storage Tab, it says Internal Phone Storage 452MB/514MB. External SD Card 1.56GB/7.39GB.
So I'm assuming the ROM has a hidden section for the system, and leaves 514MB for phone apps.
I guess I'm mainly wondering why I only have 323MB to run things in. I have been having problems with it running slow, or randomly rebooting the main interface (then it re-reads the SD cards which takes a minute). This is with just a few apps open; say, Doubletwist playing a podcast and Navigator guiding me somewhere.
I did update to 2.3.6 when that came out and it actually made my phone quite a bit zippier. I've rooted, and I use Titanium Backup to get rid of a bunch of junk that Tmobile put on there. But there's still things running that I don't want taking RAM, but don't want to get rid of. QIK for example likes to have a service running, as does facebook. I like to use Qik sometimes facebook on occasion, and I just want to start the app those times, not have it running all the time. Telenav GPS has a service running all the time too. I'd like to use that app sometimes, but don't want it in my RAM until that time -- why the service? Oh and in Services (through Settings->Applications->Running Services it says at the bottom RAM 165MB used 101MB free. What RAM is this referring to anyway?
Please someone help me understand how RAM works on this thing. I'm totally new to Android, just came over from using an iphone for years so this is all new.
The main reason you see only 323MB of RAM is that the rest is dedicated to memory-mapped devices link the video card. That lovely screen needs backing memory.

you can;t and should never need to.
You have 1 GB of RAM more than enough for any application.
Swap has not been used since Froyo I think . Since OG phones with 300 mb RAM.
Not used not needed

Thanks for replay
but this 1GB (830 MB Actually) full after open 4-5 program or 2 game And Android close automatically other Application And last States!
I Want to save last States of other program Anyway until i Close program manually
For example Chrome close tabs after open 4-5 program and when i visit old tabs , it reloaded again!

Only if you want to slow your tablet to a crawl.
Why would you want to swap very fast RAM with very slow SD memory? No need and a really bad idea.

agree. but, it looks like he's more concerned with multitasking.
it always depends on the user. let him try it first and let him decide what's acceptable for him.
Besides, "slow your tablet to a crawl" is an exaggeration.

That won't help multitasking , Android already has an efficient memory management system. That OG swap app was for Froyo phones that only had about 300 mb to run the OS and apps. No longer applies. And since there are no true multi=tasking apps. IE you can;t run two foregrounds apps. ..... , you can never fill up RAM

OK. "Task-Switching" then .
Agree that android memory management is "efficient". the problem is that when it runs out of memory the app at the "back" of the stack gets "killed". data is saved for that app so when it's called back up, it "seems" like it was running all the while.
So, as per the OP question, since his problem was that his web pages keep reloading, ie app was killed due to memory constraints, his idea is to increase the RAM or in this case adding virtual RAM via swap.
It's not a bad Idea, since the amount of RAM is virtually increased, then the amount of apps that can be in RAM at the same time is also increased.
FYI, not only for froyo, i use swap for my NEO V running ICS. made DEAD SPACE run better than without swap. :good:
Haven't encountered a need on the P6200 though. Ofcourse, there must be a reason why 2GB RAM devices are now available.
there is not reason that swapping would make your tablet run better, none.
Because as of ICS , and with 1gb+ ram, you are emulating and interfering with what Android (linux) already does .
you have one foreground task and whatever idle tasks and then unused apps that are retained in RAM until they are needed or another apps needs space and they are removed from RAM. Then they reside on SD memory so what advantage does swapping to SD memory give you, none, in fact it adds a extra useless step .
SO Android attempts to keep RAM 80% used.at all times. If you look at the process logically, I do not believe can lay out a scenario by which the swapper apps beings any benefit to current Android systems.

You actually pointed out the reason why the Original Poster wanted to use swap. he wanted his currently "unused" browser app to reside in ram, and not get killed. in this case it will be in virtual ram.
I agree with all your points. and I don't use swap on my tablet (P6200) haven't had a need, but i do use it on my phone(Neo V, 512 RAM, 384 useable).
All i'm saying is let him try. it's possible that he is hitting the limit on his Tablet. I know, cause it's easy to hit the limit on my phone that i'm very sure swapping works. e.g i can now switch between, Chrome, Facebook, Email, What'sUp, answer a phone call, send a text message and come back to Chrome (which has three open tabs BTW) without Chrome "reloading" those same three tabs. i wasn't able to do this before i starter using swap.
and yes, there's a bit lag but it's better than incurring cost of reloading a page each time, esp if your on a limited data plan.
One other thing that was not considered yet also are the OOM groups and Minfree. another option is Compcache.
The use of Swap really depends on the user and the way he uses his device. You can only see a benefit from swap if you consistently use up all your RAM. Which, if i understand the OP's problem correctly, is the case.
I own a samsung galaxy tab 2(GT p3100), which initially had 4.0.4 ICS with 687 MB RAM(but specified as 1 GB RAM, as some developers claim that it is being reserved for system). I updated my firmware to 4.1.2 and now it showed me 770 MB RAM. later i rooted my device and installed the latest CM(cyanogenmod) 10.1 (jelly bean 4.2). To my surprise this rom which has less bloatware and is smoother, it showed me 691 MB RAM, less than 770 MB as displayed by the STOCK jelly bean OS.
i would like to ask, which OS(custom/stock) displays the MAX RAM for GALAXY TAB 2 7.0(P3100)???????
as i don't ve enough internet downloading capacity(limited downloads), i can't just go on downloading all the firmwares and keep flashing everytime, SO EXPERIENCED USERS, PLEASE SUGGEST.
for more info(for my knowledge), do please tell this also--------->tab 2(my device specifies 1 GB RAM and the same does galaxy s2, but why with ICS(4.0.4) installed both the devices show different MB RAM. tab2 shows around 680 MB wheras S2 shows around 880 MB, wheras HTC one X shows 1 GB.
why is this so????? i know some developers claim that this RAM is being consumed by system or reserved for system, but why is it different for different devices, when the OS is the same?????
again if you claim that it is reserved by the android system, then WHY DO , WITH NO APPS INSTALLED TOO, I SEE AROUND 300-400 MB RAM BEING USED(300 MB WHEN I DNT USE ANY WIDGETS AND ALL, AND I STOP ALL THE PROCESSES, BY CLICKING FORCE STOP ON ALL APPS LIKE GMAIL AND EVERYTHING EXCEPT ANDROID SYSTEM AND PHONE AND SOME NECESSARY RED MARKED APPS IN THE DEFAULT TASK MANAGER).
if android process is being displayed here with this 770 MB ram, then where has the 230 MB ram gone------------>do you mean the android process consumes the hidden RAM and also a part of this RAM too???????------------------>this sounds too unpleasant, when htc one x displays all the specified RAM but my tab fails.
really disapponting
You are getting too excited about available RAM. The OS system manages available RAM so each different ROM will use it a little more or less.
The amount of free RAM has nothing to do with how many apps are stored, ONly how many apps are RUNNING. Android system efficiently manages RAM and tries to keep it about 80% full all the time. So called Bloatware (one mans bloat is another mans useful app) has nothing to do with speed , they do nothing if you don't run them.
The system RAM usage contained OS buffers, temp storage and system routines that are always loaded for speed.
1GB is a ton of RAM for android.
You do not have a RAM issue.
You can run out of SD storage space for downloaded apps if you store too many. But you have several GBs of storage so that's hard unless you are a real pack rat.

Right Sir,
well, regarding storage i dont ve any issue as some data like pics and vids can be kept in ext storage card too,but i also wanted to know which ROM provides user with more RAM, so that it will be good for multitasking or if i play high end games like NFS MW

The amount of difference between one kernel and another (which is what really matters here) isn't large enough to make any real difference in the performance of any application. The available RAM after the kernel grabs its stuff varies around 10% from one kernel to the next.
If you want to make a performance impact, make sure you minimize the number of running applications that compete for the available RAM. However, that won't make much difference as Android is very aggressive about grabbing memory back from idle applications.
Basically, you're obsessing over something that in the end will make no difference in how your tablet runs.

Irrelevant. Android will clear apps from RAM if it's needed by an app with high memory usage. This isn't windows

well, if this is the thing, and android can kill apps automatically then why do some people prefer custom ROMs like CM or AOKP.
even for installing custom ROMs they need to root their tab/phone, and if they root and want to get rid of so called bloatwares and make their OS lightweight, they can uninstall it using root uninstaller(available for free in google play)....
but why do they prefer custom ROMS?????

More features generally. Some roms will manage the memory better than others, ie at what point it starts to kill apps to free RAM(although this can be adjusted in any rom using rom toolbox or a similar app). many custom roms include a theme engine allowing more customiza. They may make better use of resources to decrease battery usage or because it has better cpu governors which will increase performance. They may flash a custom roms because it's kernel includes modules that aren't in the stock Kernel. There are many reasons besides RAM usage, since as you say you can root and remove bloatware and change memory handling(called minfree or oomut of memory)

Im on xt1033 (no external sd). Im satisfied with the performance on my moto g but i hate it when i switch app (browser) sometimes it reloads the whole page as if it closes the browser because it doesnt have enough ram. I watched a couple of vids in yt about adding ram thru sd card, sadly ours dont have external sd card. I know we can partition our internal storage, right? Anyone here have done this? So we can add it as ram? I have 16gb model and i still have 7.5gb of free storage i have my phone for 8months now so im pretty sure im not needing more storage anytime soon. Anyone wanna try to experiment on this? So we can add another 500mb or a gig of ram?
Use a different ROM which has a little different policy of managing RAM... I too was frustrated by this problem but I have tried many ROMs but to no avail...Then I tried nexus 5 experience ROM and that has fixed the problem for me...So basically just use a custom ROM

Hi, thanks for the suggestion but I'm not open to try any custom rom as of the moment. As long as the stock is the current version. I will still go with the stock.

It's a 150 dollars device... it's even too much good for its price. My average ram consumption with the phone just rebooted is around 500mb, you need to check which apps use too much ram (like 30mb+) and close them or, with root, you can prevent them from boot. Anyway, apps that require big amount of ram will always reload if you leave them in background.
As said above, you can't expect much more of such a cheap device as the Moto G.
On the other hand, 1GB RAM is still quite good amount to run you off pretty much everything. You can have insufficient RAM only if you use your phone as a computer replacement, which is very bad idea.
In that case you should get for example Xperia Z, which is way more suitable for that purpose or Note2. This will cost you significantly more cash of course.
Also you can't increase your RAM off the storage of the device, being it sd or emmc. You can't repartition the emmc either, this will most likely hard brick the device.
Swap is not a substitute for RAM and it never have been.
Thanks, i already have the boot manager via xposed module but still im experiencing it. anyway it was just an idea. Coz i have a lot of space in my internal.
I just noticed that even if i still have 100+ mb of free ram background app still reloads when reopen.

I would recommend the Android Assistant app, it has a lot of features including a boot manager and also an easy button to free up RAM. There is ads tho unless you use Adaway.
My biggest gripe with the lack of ram on the G is when I'm trying to stream Pandora while using the navigation...I usually end up driving in silence until the annoying lady tells me where to go
The best way to prevent your problem is fine tuning minfree controls...I use trickster mod to make these settings...Do go through this link...It gives you details on how to fine tune them to solve your problem...

After reboot my phone I have more than a gigabyte free RAM. But few days after that with used some apps I have only 600-700 MB RAM free and I don't know what is using it.
I mean after I stop using some app i force stop it from the app manager because I don't want it to stay loaded in the memory but don't know why the memory doesn't release.
Is Android cache some RAM without my knowledge?
I upload a screenshoot from L Speed.

Your OS using Your RAM. It's not normal for android to leave lot of RAM free. Thats not how android works. He load most used app so You can call them quick. You can google about that and read some article about how android menage RAM. I have 3GB RAM, in use is about 2 or 2.2! If i have 2GB of RAM than system used will use around 1 or 1.5gb. Every model have different RAM MENAGING! You don't need free RAM, if You start some app which need more RAM, system will immediately free enough RAM. All process have priorities, low priorities will be killed first to free up memory!
So don't wory about RAM in android OS! ?

Ok thanks than.
A certain amount of RAM will automatically be taken up by the GPU, which is why your 1 gig will be 832mb or thereabouts when you look at how much you have through CPU-Z or a similar app.
in system there are alot of apps that runs in background ie.. your messages ,dialer.. we can't stop that apps.... but yeh you can use greenify or similar to force stop your downloaded apps so your phone runs smooth.. also disable some system apps you can't use . because now days new androids come with alot of apps and we only use some apps
