[Q] Low available Ram !!! - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hey Guys ... Did you look to the Ram status in the Galaxy Note ???
I have 600+/800 usage in normal situations !!! and when I clear ram it reached to 400+ which goes back to more than 600 Mb after moderate usage !!! what about in your Notes guys ??? Any solution for this ?? plz comments ....

What is it you are planning on doing with the free ram? Has the use of ram caused any problems? Don't worry about it and use the device. There is no point in trying to worry about something which is being used or not being used which is not affecting you in any way. Until it does have fun with the phone.

Do you think Android is running on air? The Note has 1GB RAM which the OS takes 200MB at boot. The rest is used by apps and other things. If you're not going to use the RAM, then why do you need it?
"My computer uses 50MB of RAM, And i have 32GB of it!" WHAT'S THE POINT?!

Try RAM Manager by Juwe. Be aware that the more memory you free up the worse multitasking will be.

Are you kidding me? Use RAM Manager when your device has 1GB of it? Please slap me as hard as you can.

This thread needs to be deleted.
RAM is there to be used.
I would use 100% of my RAM 100% of the time if I could. If it's not being used, it's being wasted.

Unused RAM is totally wasted. When 2GB devices come out OMG my device is using 1GB out of my 2GB!!!

To each his own, who are you to tell others what to do with their RAM? I'm not your typical "as much free memory as possible freak" but how comes that when I kill some apps before running something more intensive it's usually smoother and performs better?

I've never had to manually kill apps with my G-Note, so I dont know what your doing wrong, Could be a faulty device as far as I can tell.

Thanks for your advice, I'm running to get it replaced.

600mb usage is totally normal on moderate use. Obviously you don't know how RAM Management work on Android. Go and replace your phone but nothing will change.

Would you replace your computer because it's using to much RAM?
Chances are you would find the RAM hog and keep it from starting up when not neccesary.
600mb is normal usage.... if you are not happy with that high of usage delete the apps that have services running or are always in the background. Android does this for you as you approach full RAM usage anyways though...

Ever heard of irony?
Of course I'm not gonna get it replaced I'm happy with the way it is.
Yes, I've read about Android memory management quite a while ago. Very smart and very convincing. Now on the other hand - every now and then after some intense moments - let's say I'm driving and I'm using offline satnav then online satnav then there is a phonecall, then I make a voice note, I get out, send a text, use my GTD app and whatever else - after hours of such use when I get home, stretch my legs and I fancy to play let's say Galaxy on Fire 2, I find it smoother and less likely to crash if I just press "kill all apps" button in Task Manager. And since I installed RAM Manager I don't have to do it. And I haven't noticed any side effects that would interfere with my style of using my phone.
So guess what - I really don't give a **** about Android memory management and all expert opinions because I know what works for me and I'm happy with that state of things.

I posted in this thread beacuse another user complained about the problem that I came across and found solution to. It's certainly not the best one, but it's the one that works for me.
In the meantime I got ridiculed by more social-oriented users who need to accept and be accepted. To which I got upset and posted some crap. As a result I hijacked the thread. I apologize and shut up.

Samsung makes us fool it has only 800MB RAM. Even i thought it was 1GB.

It has 1GB. 200MB is reserved for the system.

Memory usage
My daughter started a game where a photo is used in the programme, and I got the message "Free RAM low, resolution of photo reduced". Had to kill running services to be able to run it without the reduced resolution. Checked the overall Galaxy Note ram usage and just out of the box I have around 230mb free of RAM, I have an HTC Desire HD (768 ram) that has the same free and it is filled with running apps. When you get that kind of messages from a new phone, from some ****ty simple kid programme before I have even filled it up with stuff I get really annoyed. When I kill all I can i can get max up to 400mb.

Yup, TouchWiz is a greedy RAM eating whore. Wait for CM9 and then you'll see why custom UIs like TouchWiz and Sense is bull****.

How much ram should be free

My phone shows ive around 120 to 140 ram is that enough so that the phone functions smothly without laggings? And i wanna know what free ram u guys have while using ur phone ....
Sent from my DROID3 using XDA App
I mean total memory free***
Sent from my DROID3 using XDA App
Around 100MB +/- 50 free is nominal, I guess.
The way I understand it:
It's going to vary quite a bit, depending on what your doing, number of additional serviced installed, etc. But generally speaking, Android is a very different animal compared to -- say -- Windows. Free RAM doesn't really have an affect on performance, it's just RAM that's not being exploited. There are several parameters that tell the OS how much RAM should be free in a number of different circumstances, also when and how often to kill other services. i.e. As RAM usage increases, apps and services with increasingly higher priorities will be killed to free up RAM. So like if you run Angry Birds, you may start with 100MB free which will drop down to say 70 maybe even 50, but after a few minutes of running, the OS begins to try to free up memory to get it back to what ever the desired free RAM is set to. So after a few minutes, your RAM may go all the way back up to 100MB. Where Windows would just start to pound away at a page file on the hard drive, Android will start to kill applications then eventually kill lower priority services in order to free up the RAM it needs.
So basically every time you run a RAM heavy program, Android will start to kill the previously used programs (settings screen, browser, facebook, whatever), as they are now deemed lower priority. It's always fighting to maintain a certain about of RAM.
I have an average of about 150mb on the latest CyangenMod build (not ICS). However once I start up my phone and run the auto kill after about 10 minutes, I can have 200+ (sometimes as high as 250).
Bobbar said it well in terms of how much you need. To be honest, when I was on the stock rom, I would sometimes have less than 70mb free, yet my phone still wouldn't lag much. You can help with any launcher lag by disabling desktop animations and such.
I'm generally in the range of 60 - 90 MB free RAM at any given moment. My D3 does not lag at all. What you are reporting is absolutely fine.
My first phone regularly reported 25 - 40 MB free RAM at any given moment. Android runs fine on the D3 - it's best not to spend too much time worrying about it, IMO.
If you have a bunch of RAM free all the time it just means you're losing out on multitasking. Some people tweak their OOM values and such so that they have copious amounts of free RAM, this is not necessarily a good thing. IMO
Android aggressively pre-loads applications into memory. The most ideal situation is actually higher memory usage - as most apps don't need ridiculous amounts of memory to operate, and more apps cached in memory means faster launch times for those specific apps.
If you have a bunch of apps not closing and lagging your phone then try Auto killer.
Sent from my XT862 using XDA App
I've got 240MB free at any given moment with stock ROM and doesn't lag at all.
So, not to get off topic, what exactly do all these newer phones need 1GB of RAM for? Just to load up more apps into memory? I get it, it should make them load up faster...but is it necessary on Android?
It just blows me away how much these manufacturers charge for phones these days. Seems like we're just getting into the same kind of specs 'arms race' that people have been going through on their PCs for a while now, just so they can try to make more money. That's pretty sad, considering I have a fine experience with the D3 and G2x.

1 gig of RAM would be a great thing, for instance for running GNU/Linux in chroot, which I do...
The prob is the Droid 3 doesn't have anywhere near enough total RAM, not to speak of free RAM.

Well, Android has gotten fatter, for one. Another would be Motos Webtop.
The more memory you have, the more apps you can have stored in it at any one time. Devices with small amounts of RAM (256 or so) may only be able run one major app at a time. But once you get into the 512 - 1GB+ range, users can freely switch between several heavy apps without them getting killed to free RAM. So you could switch between Angry Birds, then the browser, then YouTube or Email and Messaging without having to relaunch any of them.
So manufacturers tossing in more and more RAM does end up being a pretty good selling point.

Just looks at how powerful these devices are compared to just a few years ago. The innovation and power is increasing at an almost logarithmic rate. The price for a high-end smart phone has remained about the same, but the rate at which they are being cycled for newer, faster devices is crazy. So, in this sense, it may be accurate to compare it to PCs. But, it's only us enthusiasts that really feel the hit to the pocket book, because we always want to be on the bleeding edge. And most users, average users, will stay with the same device for a long time, they don't feel the same 'pain' as the enthusiasts group.
Back in 2005, before the iPhone and all that stuff, a smart would cost you almost $700 and it came with a steaming, stinking pile of Windows Mobile. We have it so good these days.
I have around 200MB at boot (CM7).
Yes, that should be enough RAM to use most apps without lagging. That's about what I had with stock, and I rarely ran out.

512mb it's a little down for me... because i like multitasking and for example if you download something from a web page, using opera mobile or stock browser and you open facebook's app while you listening music (poweramp or winamp) it will kill your internet browser (cancel your download) due to your less ram avaible.
A great solution for us would be if we can enable a swap on our droids but it seems to be difficult (or imposible due to our locked bootloaders)... but if somoene is interested here is a link to the current topic http://forum.xda-developers.com/showthread.php?t=1407671
With swap enabled our device will move to virtual memory our background apps leaving free ram to our current app.

[Q] New to me

Hi, been using Note 2 for a year. just now I went to try out the Z1 which attract me. I am lost at a feature that is easy to go to in note 2 but I don't know how to go to the task manager in z1. I want to see the ram usage which can clear ram.
the screen image is fantastic btw.

To see overall RAM usage, go to settings, apps, then the running tab. I'm not aware of a kill all feature, but also not aware of why you would want to do that. RAM in Android is meant to be used and Android is very good at managing it on its own. People who think clearing RAM manually will increase performance are misguided. All you're really doing is forcing the system to reload apps into RAM that it wouldn't normally need to do. This takes additional processing power so slows down your phone and eats up battery. The only apps that should be manually killed are those causing problems by running too much in the background. And using kill all to fix this is like dropping a nuke when a sniper is all you need.

Yes because Samsung tends to load their phones with loads of applications and services. But the free RAM you gain after killing those applications doesn't necessarily make your phone faster. Of course, if it kills an app that is doing crazy things in the background that uses quite a bit of CPU your phone will be come faster, but the fact still remains that more free RAM doesn't make your phone faster.
Yeah Sony doesn't allow you to kill RAM... If you want to do this,Download ZD Box... Its a task killer and has quite a few more features...

My RAM usage is about that high, 700mb. But since the Z1 has about 1.6 gb of RAM, you shouldn't really worry. If it does get to the point where apps stop working or services become unresponsive, restart the phone or kill the app that's using the RAM. I believe when your RAM usage is about 1.5 GB it starts becoming a bit unresponsive.
Nexus uses less RAM because it only has stock apps. Sony has their own software running in the background along with some of Google's apps.

That doesn't makes sense. As long as your device isn't unresponsive or laggy you shouldn't bother about RAM-Usage. Android handles your available Memory quite well.
Try looking at it like this:
There isn't any use in having more and more RAM, if people on the other hand go and try to keep the RAM-usage low. As long as you don't have problems (lags or such) having free RAM is just eyecandy.
Additionally:
For every app killed, Android needs to load it from storage the next time, resulting in more battery drain than just letting it idle in memory

It's a kind of thread like this one for Arc
but for Z1 somewhere, I remember a saw that thread with a list of apps to uninstall, search for it.

Is it normal only 1,5 gb ram free?

When I reboot the tablet and look the free ram memory only have 1,5 ram free, is it the normal when this tab has 3 gb ram? I have thunderrom and skyhigh kernel installed.
Yep. It's for most of the android processes and important things that need to run. I also get that much too.

Yeah but otoh caching boat load of stuff into ram that won't be used is a waste of battery.
I look at the list of running processes with a system monitor and I have to say WTF does it just load every thing or what. It's running apps I don't even use any more but haven't uninstalled just in case. So if I don't want them running I have to freeze them. And that does not include all the system processes whose purpose I can't even tell. It's kind of nuts.

Sorry but you should start to learn yourself. The RAM displayed as free is actually used as a file cache. Besides, Android killing apps in the background means that it takes longer to start a new app in a low RAM situation (because the new app needs to wait until the LMK cleared enough space) and of course you lose the context of the closed app (it needs to reload data from the internal storage or even worse from the web when you restart it).

Are you in a low RAM situation when you have 1GB free out of 3GB? NO! 0.5GB out of 3GB? NO!
Does it take a significant amount if time to reclaim resources when android does require additional RAM, because it genuinely is in a low RAM situation? No, because it unceremoniously terminates unused processes, releasing resources to the kernel almost immediately. This is very different from garbage collection to release unused memory from active processes.
Don't just believe me though - take it from the people who actually wrote the OS - http://android-developers.blogspot.de/2010/04/multitasking-android-way.html?m=1
It's also worth saying that you've also validated my statement "Free RAM is wasted RAM" by saying that the OS "uses" free RAM as a file cache.
All that being said, the context of this entire thread is why the OS is "using" 1.5GB out of 3GB pretty much at boot. All I've said is why this is perfectly normal, and in the general usage case, actually not undesirable.
Of couse there will be specific usage cases, where this is not going to be the optimum approach, but this is only going to affect a very small minority of users, with extremely memory demanding applications.

No. RAM impact on battery life is, for all practical purposes, insensitive to the amount of RAM being used. When sections of RAM are clear, the locations are not zeroed out or anything. Instead the space is just added to a free space table. Stuff in RAM not being used does not waste battery. The exception to this is if that RAM is being occupied by a misbehaving program that is driving CPU usage.

Foxmeister is exactly right. In nearly all real world cases, higher RAM usage leads to faster performance and better battery life.

It's a trade off - preload the processes and data so that they can be accessed far more quickly (less lag) if and when required. Once in memory, if they are not being used the battery drain is negligible.
The reduction in perceived lag is *far* greater than any battery drain.

When you open a new app that is not running, you expect a delay. So as long as it's not excessively long, you don't feel lag. unnecessary preloading then just increases bootup time and long boot up time DOES bother people.
Now it makes sense to preload frequently used apps and some system apps that have high probability of being needed. But what I was talking about is seeing apps I used once once weeks ago still get loaded, while some apps I use every session, like my browser, not loaded on start up. The algorithm needs tweaking.
(Large apps like games have long load time, but you are not going to cache those so they are not in the conversation.)
Most lags people experience is in app lag. It's mostly due to loading graphics onto the screen, screen painting, and garbage collection.
What baffles me is I have an iPad 3 (there have been 4 generations of iPads since then) , which on paper is like a Toyota Camry compared to the Tab S BMW 300. And yet on many same apps the iPad feels smoother, scrolling around is less jerky. The only place where the Tab S is superior is 3d games like asphalt with high details and because it has 3x memory, apps need reloading less.

The vast majority of users (i.e. the sort of user who doesn't frequent sites like XDA) probably don't reboot their tablets/phones very often at all, so most people probably aren't that bothered.
I rather suspect that the engineers at Google have experimented with an awful lot of different strategies, before settling on what we have now.
Is it perfect? No. Like everything software related, it could do with improvement but this is always a continuous, on going process

[PSA] Memory Leak still present in 5.0.2

Not sure if you all know this or not but the memory leak from 5.0 is still present in 5.0.2. Screenshots show it. First is before restart, second is after restart.

So u conclude this only because less ram is free ? Or the device becomes unusable?
Pretty sure everyone knows, and if you look at a changelog there was no mention of it being fixed: http://aosp.changelog.to/aosp-LRX22C-LRX22G.html
There are commits that fix a memory leak (https://github.com/Lethargy/android_frameworks_base/commit/da2133d046e59b590e51448eda31d710da217d40 and https://github.com/Lethargy/android_frameworks_base/commit/e30ccdbeac2c53b04a389c7ffd8e9d500c93ef30), however I do not experience such memory leak myself so I cannot say if it fixed the issue for others.

Just asking regrading the 2 links you posted... Is it the screen off animation causing the memory leak and maybe if you switch off the animation in developer settings will it fix it?

I'm not sure if those commits fix the memory leak that is widely experienced by some users. I only know it fixes "a" memory leak. Again, I did not experience a memory leak myself before merging those commits to my ROM source, so I can't comment on whether it helps or not.
Not sure if turning off animation will make a difference or not, but I don't think it will.

I conclude this because yes there is less RAM available and it then causes the device to become very laggy and difficult to use.

Always got to have one pedantic one. Yes the memory leak still exists.
So is there any chance to fix it?

Stock 5.0.1
Also 3 Day usage with 3 h sot on data (3g) and wifi on but connected only during 22 to 10.
There's a memory leak?
1.3Gb free here, been on stock 5.0.1 for something like a week now. Maybe there's something else eating up your RAM.
Some say it is the Google Experience Launcher...

This memory leak obviously is not hitting every device, me and 2 of my buds are seeing this issue (system fills up RAM and handling the device becomes a struggle), while a fourth friend is not seeing it on his N5.
3 days ago i ditched the Google Now launcher and returned to Nova, and i think the problem is not that severe anymore, but i have to keep an eye on it for a bit longer to be able to say for sure.

How is this a memory leak? When more memory is needed, it will open up. Contrary to a long time "windows user" mentality, using memory is good. Especially on android. Why do people think using ram is bad? Using ram helps speed things up.
On a semi side note, after perusing computer forums for many years, I've seen many people get as much RAM as possible then try to get their systems to use as little as possible. It makes no sense. RAM is your friend. Use it.
I haven't had this 'memory leak' ever..even from 5.0.0
Yes using ram speeds things up but only when its being used for things like caching preloading and keeping apps in memory. Even then too little free ram can result in lots of paging when using multiple apps so the system tries to achieve a balance keeping some things in memory while having enough free to not cause paging. In this case people are reporting the opposite that after a few days the phone becomes slow and laggy and memory usage is very high even when they have no apps open so there is no swapping it paging going on. If it was just the is caching things it would just delete them to make room for the current app but that is not the case, the only explanation there fore is that something is leaking memory and consuming it till there is very little left for anything else. Also the os might not be managing memory properly but that seems unlikely as android has always been pretty good at memory management.

I'm thinking the highly modified ROM/kernel combination might have more of an effect on OPs free RAM than any "memory leak". Stocks working just fine. Still 1.3Gb free after games, forums, screen on/off, been on for three days, etc.
Can't post screenshots with XDA one app?

I don't think so.. i have the "laggy phone Problem" with 5.0.0 and 5.0.1 . Always absolutely stock. It's very frustrating...

It has nothing to do with amount of free RAM. As shown in my pictures you can see 600 mb free ram, but phone starts shutting down apps. This happens on stock ROM without installing extra apps too by the way. Navigation and google music streaming quickly makes this happen it seems for me.
Duh, most of the changes for 5.0.2 were for Tegra N7.

It's not the usage of RAM the issue, I think it's more about RAM management, if bigger apps need more RAM let them take it up. But the issues arises when the OS does not release the memory take up by the previous app back into the pool, so then each time we take the same program it takes more and more of the space until other apps cannot access it easily. Presto launcher redraws or apps fc's(or not even running or abruptly stopping the background music playback service) in phones, and whole system freeze or "hang" of the OS in desktop environments.
