Missing RAM?

Hey guys,
I just got my brand new Nexus S yesterday from a Mobilicity store, and I just noticed that after using it for a day, in the Application Settings --> Running Services menu in system preferences, it says that I have used 179 MB used and 116 MB free, that only equates to 295 MB of total RAM. I thought this phone had 512 MB of RAM installed ... what happened to the rest of my RAM ?
Does Android reserve like 200+ MB of RAM for the OS itself ? Personally I disabled the Live Wallpaper as it eats up resources.
Software I do have running in the background right now are: RealPlayer, Trillian, LiveProfile, Skype, Maps, Swype.
Thanks,

Yes it does, that's normal for OS based phones...i think you prolly have more programs running because the best amount of ram to have is around 200...

I think they should have a much better memory displayer ... like in KInfo on KDE which lists, free, reserved and used.
Without that, I was like, wtf happened to my 512 MB RAM? lol.

get a terminal emulator app. Type in "free"

Ye I was originally quoting that screen but the main issue is that I believe that its memory manager should show total free, total used and reserved spaces than just listing what isn't reserved.
Personally I thought my dealer shorted me out by selling me one with less than 512 MB RAM, then I came up with the possibility that it's just OS reserved which has now been confirmed.
If I was not very tech savvy I would have gone back and say, wtf happened to the rest of my memory? It could have been shown better or had an advanced view.

look at the bottom of that screen, it does show free ram vs used ram.
also, a lot of ram goes into nfc, not just the os. ive been with the ns since the first week of the year, and i havent had any issues with not having enough ram. also, theres an app called free memory manager(by angry squirrel) that you can use to set the native task killer, so that youll have more free ram more often. here are my settings at the moment, they are very aggressive..

One XL Rogers LTE Ram size

Hi everyone,
According to XL Rogers specs, I might have 1 gig RAM but I only have 671 Mg.
Is it some king of Rogers limitation?
Can someone having a Rogers One XL release can confirm that?
Annoying because even with a few application in process, Sense is randomly restarting because, I think, of a lack of memory. It often happen right after using a browser for few minutes
Thanks!

I noticed that when looking at ATT One X
Would like to know as well. WTF..

i could be wrong but i think it's because the memory is shared with the gpu.

Weird because it shows 1Gig in parameters/hardware Info.
But still 671 in memory management and benchmark utilities...

That is normal. Some parts of the memory are reserved (for OS, GPU etc.) and are not accessible for all apps. For example, my Galaxy Nexus has 1GB RAM, but only "693 MB" is displayed under "about phone". That has always been the case for all Android phones, although how much of the memory is reserved differs between phones/ROMs.

I wonder why this always comes up when a new phone is released. When people buy a computer with 6 gigs of ram, do they get mad when Windows or OSX uses 2 of it?
It's the same concept here, but this always comes up.

If you run:
cat /proc/meminfo
That should give you all the physical memory available to Android.

It's not really the same concept, as that has to do with the 32-bit limitation. And yes, people did complaining a lot a few years ago when 4GB RAM started to become really affordable. People rarely complained about that these days, not because they finally understood the issue, but rather most computers are shipped with 64-bit OS now.

When you load up task manager in windows, it shows how much free memory you have. The amount of free memory is NEVER what your total physical memory is. There is always about a third used for cached data, OS processes, and stupid widgets that you have running on the desktop.
Nowhere did I mention the 32bit limitation, that would be a valid issue.

150ish meg for ramdisk and another 150ish meg for GPU. Explained away.
This is common on every phone that's ever come out for the last year + with 1 gigs of ram.

That's free memory that you are talking about. Its total physical memory and I and OP were saying. My Windows 7 task manager always shows the actual total physical memory, and that wasn't the case with winxp before either sp2 or sp3 and tons of people whined about that on a daily basis.
The OP's question, however, concerns Android and it doesnt show the correct amount of physical memory on the phone. He is not saying "free memory", which is of course changing all the time depending on running apps.
Sent from my Galaxy Nexus using XDA

I am seeing a total of 970ish MB's on my international htc one x. Currently 709MB used and 267MB free.
I believe some of the RAM is reserved for the GPU and since there are different GPU's in the two models it is probably what makes up the difference in available RAM.

for real Samsung u managed to put 1GB more than Note2 and 1.3GB more than GS3
the 1GB more = more services + more Apps running in the memory = less free RAM = more lag
free RAM on GS4 VS Note 2
many apps opened in background with all features on
BTW GS4 have about 100MB more usable RAM than N2
GS4
NOTE 2

You're still luckier than me, since I live in China, my I9500 comes with a bunch of crap Chinese software embedded into the ROM that I can't remove. Also mine doesn't have Gapps, no Google Play, can't even add Google Account. Browser also doesn't have any trace of Google, no Chrome bookmarks sync, and search engine is Baidu or Bing.

Multitasking better be good on this phone. Free ram is wasted ram but I don't want it to be anything like the s3 in terms of memory management

Free RAM is not wasted
Free ram will be used to cache apps and running apps in the background
When the free ram become too low LMK will start kill apps
and im not sure how it compared to GS3 in real life but im hopping it wont be worse

Well, I install Google Services Framework apk, and installed Play Store. First time it won't open, so I tried another version, it opened, but says cannot connect. Looks like Chinese government/carriers have done more than just removing the Google apks from the ROM.

I think what he meant is that free ram should be used up to help speed up apps. Instead of caching 64mb and dumping memory more often use up 128 to 256mb and let the app run wild, and when you're done android will either keep it cached, or dump it if another app is opened.

This
No point in having 2gb of ram and only 500mb is used. The extra space can be used to cache apps you use frequently or will are more likely to use. However, its also foolish to have 2gb of ram, and the system is taking up around 1.52gb out of 1.82gb of usable ram. That leaves the user with 300mb of ram for their custom apps which is the same amount of ram I have left on my S3 before my custom apps are cached.
Once I've used it for around a day without a reboot, my free ram hits around 100mb with the LMK starting when the device gets to about 70mb. I want to be able to have a good few of my custom apps in memory without fear of them being kicked. I would also like to be able to quickly reply to a text mid-game and not worry about it being dumped the moment I switch away from it.
Based on the example above, I could load a bunch of apps into the note 2 whilst I'd be SOL on the S4

HMM in another forums someone got the Octa version and he said when all the features on with many background apps running used RAM about 1.25GB
and this with no features ( just auto rotation and smart stay and wifi ) :angel:

Thats why im going to cough up the 50 bucks for a 64gb sd card and leave the internal strictly for apps and such. Yes its another 50$ but the 32gb model is probably a lot more than that to upgrade if you ever find one

Indeed, but at least you wouldn't feel limited in the amount of apps you can install with a 32Gb model (which I'm waiting for).
With 9Gb free, I'd have to make a choice on what I want to install.
I already have about 10Gb worth of apps on my SIII after making a clean up, and I have almost no games installed currently.
My 64Gb microSD is used for pictures, videos taken by the camera as well as music, the occasional movies, iGo maps, ...
If you want to install bigger games, you'll quickly feel the limit (some games take 2-3 GB).
Well you can always use something like DirectoryBind to use the SD Card, but it really shouldn't be something you have to do on a flagship device.

Wondering why the S6 can't hold apps in its memory?

Well, if you have wondered why, I think I may have the answer.
Samsung made a claim that the new Touchwiz is stripped down and optimised for better performance, well, they LIED. True optimisation isn't easy, but another manufacturer did it - HTC. Below are the two screenshots of the respective "Running" app section of the settings and see the difference? 1500MB vs 355MB. 5 times more.

My S6 is running the latest version of Touchwiz, COGA, and the M8 is running a lollipop custom ROM ported from the M9 (sort of). I sincerely hope Samsung will fix this issue, as even the 4GB RAM Note 5 and Edge Plus are also experiencing app shutdowns. What are your experiences? If you have a solution, please share. Thanks!

Agressive memory management and Sh*twiz cached in RAM causing this. Some custom kernels are better than stock, but no fix as of now.

8GB ram is a must for TouchWiz

Again:
the workload of the ram is not the problem!
I'm running a very stripped down TW rom and I never reach a full ram. I am around 80%. The Problem is that the system is killing processes to early, even if the ram is far away from being full. That would happen with any amount of ram.
Yes Samsung should fix this or should have already fixed that issue.

Yeah it f*cking sucks. It's rendering my g watch unusable since it's aways killing the wear app

they didn't do nothing to optimize its almost the only software to eat all the ram.. it was always like this, and now in the s6 it reloads apps.... normal..i had an s3, s4 and now s6, you can have 3 apps in background nothing more....

yes, this ram freeing by killing apps is somehow intentional

According to the samsungmobileuk twitter person there is no issue!
I even sent them video demonstrations. The s6 cannot multi task as well as a 3 year old nexus 4 with less memory.

In my s6 applications running in the background, and it does not kill them
but my Ram is 75% all the time..

There is no reason for RAM to stay empty. It's very normal for an OS whether it be Windows or iOS or Android to use up all available RAM, that's the way it should be.
S6's problem is not that RAM is almost full all the time, which is normal, but that background applications get autoclosed after a short time, which is a kernel setting. My guess is that Samsung does it to save battery rather than RAM, since background apps eat up a lot of battery.

Spot on well said. Have a thanks

samsung will be always like that, i remember in s3 the same problem just worst because of lag, then s4 still laggy with touchwiz, s5 better touchwiz and still laggy, then our s6 with 3 gb of ram cant hold 4 apps in ram compared to other phone that doesnt have the crappy, useless, laggy, and ugly SH*TWIZ. Samsung always be like that and they will never fix lag and ram problems never. even S6 Edge + with 4gb of ram Still the same crap with touchwiz.
i hope cm arrives to our s6, if not we will be screwed in the new android update 6.0 marshmellow.

I think more to the point, WHO gets to use the memory is what matters. In Sense, the streamlined system processes takes very little of the available ram, and the apps get to fill the rest. In Touchwiz, it's the other way round - system sucks up most of the ram. I think the key to allow more apps in the background is in reducing the amount of ram system is using on top of less aggressive app killing.

For "Used RAM is not wasted RAM" guys...
System RAM is WASTED RAM in the sense that there are less RAM available for multitasking. Period.

I already commented on this topic on reddit. Here's the link: https://www.reddit.com/r/Android/comments/3i8hgs/slug/cue76g4
Also don't forget to read my reply to one of the comments where I explain why Samsung decided to have this aggressive memory management.

This would be true, *IF* things were being killed because the system is out of memory; however, that is not what is happening here... even with memory to spare, things are getting dumped.

Yes I am fully aware what he issue can be resolved by a ROOTED user in minutes but out of reach for most - I did it myself on the 5.0.2 ROM. But even though samsung promised to fix the ram issue in 5.1.1 update, fact is, people still can't open apps and leave them in the background. I hope they will release a "fix" and make the value what they should be.

Question How much ram+swap on P7 Pro?

I am curious, since my 6a feels pretty low on ram.
This has...
Ram: 6gb
Swap: 3gb
To see the value, install RAM Truth from Play Store.
Thank you!
Ps.: Swap is like a virtual memory. The phone "extends" real memory by using the real phone storage instead. This is obviously much slower than normal ram, but it allows for more multi tasking for example.

Oh for me it's just multi-tasking. I need to switch between a few apps due to work and the ram is just really not enough. But I can't find a similarly good price/value device on the market. Like the Redmi Note 12 Turbo sounds amazing (cheap with 16GB of ram), but the band support is awful.

@h8Aramex
Your ram should be more than enough. It could be a problem with the ram manager, custom kernel or your setup.

I just think my use is a bit more "power user". But my wallet sure ain't.
I fixed it though, very easy:
- made a new folder on /sdcard/
- fallocate -l 8G swapfile
- mkswap swapfile
- swapon swapfile
works like magic.
Also the "SmartPack Kernel Manager" is able to modify stock ZRAM from 3GB to 4GB.
System is stable, swap is being used, multi tasking through the roof.

You're talking about increasing the ZRAM size?

You can do 3 things.
1) Increase ZRAM within the allowed limitations. In Pixel 6a, its 3GB stock, you can increase it to 4GB. To change the value, use "SmartPack Kernel Manager".
2) You can add regular SWAP, which is like ZRAM, just not compressed. You can use the commands above to create a blank file (fallocate), create swap (mkswap) and activate it (swapon).
To activate it on boot, just schedule it after boot.
3) Using a custom kernel, you can increase ZRAM above 4GB. As far as I know, the stock kernel won't let you go above 4GB. But compressed ram (ZRAM) is finicky, you are using the CPU to compress/decompress its contents of it, while regular SWAP is uncompressed.
This way, I have 6GB RAM + 12GB SWAP (4GB ZRAM + 8GB SWAP).
Few "FAQ answers":
> you are putting writes on your storage
Yes, but no. ZRAM also puts writes on it, and you put writes on it if you use a phone. I sold my phone 2-3 year old without a single scratch. I baby them way too much already. This won't hurt a thing. I know people who torrent on their phones lol.
> SWAP is slow
Compared to disk, yeah, but modern phones use UFS3.0 and better which is pretty fast.
> I don't like what you did, I hate you
Ok. That's why we use Android, so you can use it your way, I can use it my way.
> just buy a phone with more RAM
The whole situation is silly. Xiaomi can put 16GB of RAM in phones and sell them in China for like 400$. Everywhere else? Enjoy your 6gb or 8gb bro. Who needs more for TikTok anyway. Want more RAM here? How about a 1,600$ Pixel 7 Pro?
Also, OS like OnePlus will murder anything above 1 app so 12GB really comes in handy on their phones. I had several, absolute garbage. (fool me once, yes I'm dumb.)
Bonus: You can also tune swap behavior, swap priority. By default RAM > ZSWAP > SWAP is utilized. But you can also adjust swappiness. ( https://www.electronicsworld.co.uk/optimising-the-android-platform-for-power-efficiency/9909/ ).
