512Mb RAM - Getting it out ?

I have a Flash application that requires ~130Mb of RAM and I want to run it on my Galaxy S
I've installed Froyo JPK with latest flash 10.1, but just before the end of startup procedure I always get the "exclamation circle" icon which is apparently the "out-of-memory" message in flash.
I have tried to free up the memory with task killers and memory boster, but can't get it above 175 Mb, which is obviously still not enough, since probably browser and other applications/services use it back before the flash application starts completely. Or might be also some limitation my browser in Galaxy S ? -> see EDIT below
On HTC Desire this same application works like a charm.
So I wonder...
Is there any way to get more free memory ? [EDIT: Yes, with "Chuck Norris mode" app killers, but i does not always help and it's lame]
Is there any way to get more than 311-322Mb RAM used for Applications ? [EDIT: Yes, when developpers will found out the way how to get less memory used for video codecs or even found the misterious 32Mb which are yet nowhere to be found]
Can we expect to this memory issue to be solved in future Froyo releases ? [probably only Samsung knows that, but for now it seems very unlikely]
EDIT: Found out that I get out-of-memory with every single application when it reaches 128Mb of RAM usage.
This is again specific to SGS. Looks like this is some internal max memory allocation size per application/VM
So here is another question:
Is there any way to increase this limit (might be android internal or dalvik VM related)?

no
no
no
sorry to say that...

If you need that amount of memory you should use a computer.
Its not the phone thats the probem here. its what you try to run.

I would personally put up money to get the RAM issue resolved.
People keep saying that 324~ MB is enough. That's not the point though. The point is that Samsung advertised 512MB. Any reasonable person would assume that, like other phones containing 512MB of RAM, that the phone would have 400+MB available for general usage. 324 MB for such a power phone is dismal. I consider Samsung's claim to be a form of false advertising. Yes, technically the phone has 512MB of RAM, but not according to the reasonable expectations of a consumer. Almost half of the stated RAM isn't usable to the end user for applications. This is a problem with the phone from the standpoint of delivering the expected value to the consumer.

Dear XDA Developer Legends,
Do you think it is possible that you will be able to free up ram that is allocated to the ram disk?
Yours,
Concerned Customers

Hm, maybe its applicable for a lawsuit?

the phone has 512MB and you can use all. But the system use some of it.
Its only user that cant read and understand how it work hat keep asking about it.
And this phone has more ram that most have. So yes it is enough of ram.
'If you try to runt 50+ all time you will and up with low memory.
But its the same on a computer. none complain about that.
Only that you can only see 3.5GB on windows and use that on a 32.bit system. Well now you can see 4GB and all people are happy.. but they still cant use it, but its looks good.
That the same with this phone.
If samsung did show 512MB and did show how much that was free, all people that complain would be happy. but it dont change a bit what thay can use.

there is no reason to get less memory with the i9000 when comparable devices like the nexus one running the same OS version has 100mb+ more free ram

This misses the point of my original statement. The Nexus One is advertised (along with many other phones) as having 512MB of RAM. The N1 has 380-400+MB available of RAM available for applications, as do many other phones containing 512MB of RAM.
Yes, the system does reserve some for certain system functions. Even after those functions have been reserved on other 512MB models, the vast majority is still available to the end user. This is not the case on the Galaxy S series. This is evident by the original posters comment regarding his application.
To address your Windows example: Windows 32 bit actually states that only a portion of the 4GB is available for use. I don't see in the advertisements where Samsung states "Contains 512MB -- 324MB available for actual usage"
I think most consumers, like myself, would assume that the amount of RAM advertised is directly correlated to the amount usable for applications.
Otherwise, what's the difference between a phone advertised as having 384MB and the Galaxy S? They both could have the same amount of RAM available.

+1 for the rest.

This is what i get if I run top command from adb from a freshly booted phone:
←[H←[JMem: 296300K used, 15048K free, 0K shrd, 6968K buff, 134720K cached

Wonder what this "cached" means.
Can somebody pls run this on HTC desire ?

I don't think our phone has 512mb of RAM physically available to the system. I think the phone has 512mb of RAM in total but it looks like 128mb of it is graphics RAM or something. Meaning we only have 384mb available to the system. The maximum amount of RAM I can ever get free is about 175mb so I don't think that it's reasonable that the system is using about 337mb of RAM. My desktop linux system uses less RAM than that on boot.

Isn't the memory allocation for graphics dynamic?
how often does the graphics really need all that ram?
any why aren't other devices affected by this? (doesn't the GPU on nexus or milestone for example need memory allocated?)

Please explain. Which ram disk do you mean?

Also, since it runs on linux, cant we assign some space from the internal sd (or external) to make a virtual ram disk that would be used as ram when needed? some king a paging file that we know on windows...
And if this is possible, can we assign it to video so graphism will be a little slower but app will become faster?
I think there is something we can do if we can change assignation of ram, apps, and video to make this phone way much powerful.
(just an idea...)

As you can see, all other Android phones reserve some memory to the system... It's just the way it is.

the sgs kernel creates amemory blackhole, that is, it starts using memory after a certain memory address.
It does that because many things in the hardware are using fixed memory addresses to allocate their own memory which is not managed by the kernel itself and the kernel will never touch or see it.
what you call "system memory" is usually memory used and seen by the kernel, for the OS's functionality: various applications, services, daemons, kernel daemons, kernel memory itself (its not much) and some time some ramdisks.
Every phone also uses that of course, which amounts for like 80-130megs. They also often use small black holes of like a couple of megs, but that's so little that no one will notice.
The sgs makes a big blackhole. To me it's more of a design fault, but not much you can do about it I guess. It would need someone who's going to read the complete hardware sheets to bypass that, if at all possible, lol. Or samsung.
I bet they fixed the design issue in the galaxy tab and either the chip has separate dedicated memory either there's no blackhole.
Another theory why the blackhole is necessary is that there's a bug in the chip and it's messing up a portion of the memory, so this portion is left unused (blackhole'd - never seen by the kernel) for stability reasons.
i hope this gives some insight.
reference from the previously linked post:
- Galaxy S [2.1] RAM = 512 MiB | Linux = 325 MiB | Reserved = 187 MiB (with I9000XWJM2 firmware)
notice the huge black hole here (187 megs)

I used to have more than 300mb free after reboot with nexus one...

No, *we* can't use it all , because we != system. The debate is not whether or not there is 512MB of physical memory; there could be , since Samsung advertises as having 512MB, but its not all user accessible memory. We don't know for what the system is utilizing that memory, I don't think its for loading some of the core system components; otherwise we should be left with more free RAM like other devices with 512MB of RAM (i.e Nexus One). Its more likely that 188MB is used by either the GPU and other hardware or as a Ram disk.
In contrast, other phones having 512MB of RAM don't use user allocated memory for system or hardware use (at least not the same way Samsung does). They are somehow handling it differently, maybe their GPU's and Other hardware software counterparts have dedicated memory. Whatever said, at the end of the day in the user's point of view, Galaxy S DOES NOT have 512MB of RAM as what we were all led to believe . That is pure deception !!
If they knew this was the case then they should have alerted this to the users. For-example a spec sheet for Samsung Fascinates says 512MB Flash/384MB RAM they should have advertised Galaxy S like that instead of lying through their teeth.

Nokia Lumia 620?

Hello there. I just wanted to get some advice from windows phone veterans.
I currently own an android device and I want to purchase a secondary phone. My choices are either blackberry or a windows phone 8. Or another android device.
I really want to try windows phone 8 but I'm still hesitant since I've never used any Windows mobile device before.
I also like to install apps and games, that's why blackberry is currently under wp8 on my list right now.
Can someone tell me the advantages and disadvantages of wp8. And, also, will getting a mid tier device like the lumia 620 affect my possible wp8 experience? Aside from being a budget phone, it is the only wp8 phone that I know of that has memory card support. And I need external memory.

I've been into android for long and currently own s3, I bought the 620 few weeks back from Singapore! It's a pleasant experience & different from android.

Samsung Ativ S, Nokia Lumia 820 would be the more high end devices that feature SD card expansion support. The Lumia 620 is 512 MB RAM device which some Apps (especially games) do not support (you will not be able to install them). Aside from that a Lumia 620 should be similarily fluid in usage as faster phones.
As for the memory card support: you can only move Music, Pictures and Videos to the SD card. You can not install Apps there or have Apps store their data on the SD card.

This is bull I think. Everything I've fed to my "beastly" 620 has worked. So what apps or games in your experience do not work and you've verified not to work?

I use a Lumia 810, having moved from a galaxy s2. Apps seem to the biggest thing to get used to
YouTube - I use Supertube
Tumble - I use blueprints
For an android looking contact manager grab contacts off the store.
UC Browser is a good companion to internet explorer and I've found it quiet useful.
For a live battery meter I use battery meter pro and amazing weather hd for live tile weather.
Snex8x for snes and vga8 for gba roms. I have alot of games and more or less there the same as android offerings.
Hope this helps. No file manager app at all though ?

I recently bought the 620 after some years of Android budget devices.
All I can say is: it may not be the most dev/ROM friendly operating operating system, but after sorting out the multiple-google-calendar problem (caused by Google!) I must say I'm really happy with it.
Currently sorely lacking:
- dropbox support
- no app for my bank (ING) where there was one for Android and iOS
I really like the way social networking is integrated in this OS.
Some small issues I see:
- idiotic implementation of sms delivery confirmation (you get an sms back instead of a checkbox in the sent sms)
- only one volume setting
My previous smartphones were:
- original Samsung Galaxy (piece of crap)
- LG P500 (loved it and still like it a lot. Girlfriend's phone at the moment.)
- Sony Xperia Mini Pro (loved it, dropped it, screen broke. Will keep it for modding.)
I hope this helps...

Currently have a Windows Phone 7.5 device (Focus 2); now have a 620 on the way. For me, the main difference is that iOS and Android are all about the apps. You go to an app for Facebook, an app for twitter, an app for contacts, an app for e-mail, etc.
Windows Phone bakes all this in. It's People Hub, for example, is a contacts list, but it's more a communications center where you can see your friends messages, Tweets, and Facebook posts without having to jump around to a lot of different apps. It's smarter and you get more out-of-the-box, before you even install your first app. (It used to take me two days to get a new Android phone set up with the right apps and widgets to make it usable - a new Windows Phone is ready to go as soon as I've added my Google, Hotmail, Facebook and Exchange accounts.)
The DISADVANTAGE is that your favorite apps may not be available on WP. There will likely be lots of apps that do what your old app did, but if you want that old familiar Instagram (for example), it's not there... yet. Also if customization is your thing, look elsewhere. WP is focused on making your phone as functional as possible rather than as unique as possible. (Not that there's anything wrong with that; it's just a different approach.)
I encourage you to give it a try. As with any new OS, it helps if you have a friend around that already has WP and can show you the ropes. The Microsoft visual interface is very clean, modern, and spare. Which is another way of saying that there aren't a lot of visual clues that will guide your through finding your way around. Fifteen minutes with a buddy is invaluable.

It seems 512 MB ram is enough for %95 of applications and %75 of games now.
But big problem is on disk storage. My Lumia 620 has 8 GB (7.28 GB usuable) disk storage You cannt install applications to the SD card.

Temple Run won't run on 512 MB devices, Asphalt 7 Heat did not work until a recent Update. The newest version of Tune In Radio does not work (only the older Nokia specific version). The list goes on with the recent releases of Batman and Spiderman.
Sometimes there are updates that make it work on lower memory devices. This is blocked through the Store so you won't be able to install them if the developer opted out of it.
It simply is something to keep in mind when opting for a low - midrang WP8 device. It's not that different on Android though (some Apps don't support all resolutions, etc.).

I have been using Lumia 620 for a few days now. I am extremely happy with it, Alhamdulillah. I have used two budget androids before (SE Xperia mini pro and Micromax A25). I liked the customization of android, but you have admit it, you don't really need to customize your phone every day. The brilliantly simple UI of WP8, the coherent look on all apps and the buttery-smooth performance - I am enjoying a new level of smartphone experience. I know there are androids that will give me similar smoothness, but they are pricey. I didn't find any android (or apple for that matter!!) that could match the performance at this price point as Lumia 620 does.

How Much RAM Does Windows Phone 8 OS use On Startup

Just wondering cos this will influence my next decision, so should i get a phone with 256, or 512 or 1GB.

Lets just say - the more, the merrier, u get me?
More RAM means more tasks can be done simultaneously in less time. So go for the highest amount of RAM possible.

true, but will i miss out on anythig if i get a phone with 512mb ram?
i am wondering between the lumia 720 vs the 820. but i am interested in the hd front camera of the 720, which the 820 lacks. i know it will work, but will i have to close apps and stuff? anyone ever run an emulator of windows phone 8 and seen how much ram it actually "needs"?

On 512 MB devices Apps can use up to 150 MB of Memory. If they exceed that treshhold the App will be killed by the OS. On 1 GB devices it's up to 350 MB. This does not mean that the OS is taking up all the rest but there is reserved space for Background Tasks like a Navigation App running in the Background or Skype waiting for incoming calls.
There are no WP8 256 MB devices. Those were only possible with WP7 and had severly limited background processing due to the low Memory.
Certain Apps can't run with only 150 MB of usable Memory - especially games, so developers set a flag in the App so it can't be installed on low Memory devices. Of course most will try to get their Software running on as many devices as possible but sometimes it's just not possible.
The 820 would still be the safe bet.

Apps can use 90 mb on 256 ram devices, 346 on 512 and around 700/800 on 1GB device.
If an does not have enough memory to run but does not exceed the above limit, system automatically tombstones older apps to free memory.

cool, thanks for the info guys, appreciate it
EDIT: just a sec, the vales by StevieBallz & mcosmin222 are quiet different...? am confused.

My info is based out of the DeviceStatus API from the SDK.
The system holds around 130 MB for background tasks.

Here is Microsoft's documentation on the Topic in MSDN: http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj681682(v=vs.105).aspx
It depends on wether you use WP7 or WP8. I was talking about WP8 only - WP7 is somehow different because there is no fixed Limit enforced by the OS until it actually runs out of Memory. In WP8 those are hard Limits. For WP7 there were 256 MB devices, for WP8 the Minimum requirement is 512 MB.

Well, that's kinda funny, that WP8 has more memory and can't use it.

The Memory is reserved. The reason is that the System should work predictably - both for users and for Apps. If I have a Navigation Software running in the Background it Needs a guarantee that it will have enough Memory available. I can't just stop Navigation because the Facebook App is loading a big Image. Or if I receive a Skype call I want to talk to someone but perhaps would not want my currently active App to just be closed down because it takes too much Memory. So: no, the Memory is not unused. If Apps don't use their alloted share it is also used to Keep several Apps available for fast switching (e.g. Twitter is still in Memory but asleep).
That actually is an improvement over WP7 were an App was regularly only allowed to use 90 MB of Memory. This was not enforced by the OS so you could go above it if there was enough space available. The Problem was that at some Point it would run out of Memory and then would be killed. That would sometimes happen at 90 MB, sometimes at 150 MB. So a developer could test his App on his device without background Music, etc. and see it crashing all the time on people's devices. This Situation can no longer occur.
The Basic Problem is that Smartphone OS's don't use virtual Memory like on a PC. There if you run out of physical Memory Little used data is swapped out to the hard drive (which slows the System considerably). This normally isn't done on Smartphones because it is taxing on the Flash Memory. 256 MB WP7 devices still implemented it to allow them to even run 90 MB big Apps and Background process were completely deativated on those devices. WP8 also Needs more Memory for the OS itself than WP7 did.

Yay, thanks again guys

[Q] is there any know way to remove 1gb ram limit?

I understand that if an app have a 1gb ram requirement there must be a reason behind it, but i just discovered that Microsoft Research's Face Swap needs 1gb too.
I have a Lumia 720 and i'm used to have face swap app even with my old win 7.8 phone, it looks like a stupid and non-sense limit.
I tried to download the .xap from web store but it's encrypted so i can't do much. Someone have already lost some time on this?

You would have to edit the WMAppManifest File inside the XAP to remove the Limit so unless you can decrypt it you can't remove the Setting. Best idea might be to contact the devlopers though. I don't believe they would set the Limit unless they have reason to do so. It definitely is not set by Default.

How can we see 1GB ram requirement on the application page? I have lumia 620 and I cant install it too.

the only way i found to read the "1gb ram needed" error is open windows store application's link from a qr code and then tap on the error message on the phone.
looks like we totally need 1gb for this :\
thanks StevieBallz for the explanation.. i hope someday wp8 will just optimize ram management and remove this limit! I suppose is possible, iphone 3gs with 256mb of ram can run heavy games like real racing 2, why a 512mb ram phone can't run a face swap application?

512 MB devices offer up to 180 MB of Memory for App usage. 1 GB devices offer up to 380 MB of Memory for App usage. The rest of the Memory is reserved for the System, Background Tasks like playing Music, Voice over IP calls like Skype or Background Navigation.
Basically if the Devs put the effort in to get their App running with a Maximum of 180 MB it can run on 512 MB devices. If they Need more Memory than that they'll have to Limit the App to 1 GB devices. There is nothing Microsoft can do to Change that, given that it's down to the Apps Memory footprint. I can't imagine that an App can use > 180 MB on a 256 MB iPhone so it's most definitely down to the Developer to Change this.

This is an very interesting theme!
I think windows phone hast problems work with pictures and the memory limit.
Yesterday I have upload an app to store names Picture Ripper Project.
This is an mass picture downloader, that downloads pictures from Internet websites to phone.
The user can create his own lockscreen and tile images cycler.
In the first version of this app I have so many problems with the SYSTEM OUT OF MEMORY!
When the Engine downloads 15 Pictures with an size from 300 KB, the app has shut down.
I don't know why the Memory of this pictures expands over the Limit!
Now I have write down two new download engines. The Image Downloader and the Image Links Downloader.
I have create an way to download up 100 pictures at once and its working if the size of the pictures not so big.
I need some tester for this app. I only have an Lumia 920 and a Lumia 820 to testing it.
If your interest, send me an PN and get the App for free when it is online!
Thank you!

This happens because you keep the pictures in memory, and do not free/close/dispose the file streams after download. The actual size of an image in memory is bigger than its size on disk. There is no problem with the system. Just your app is doing it wrong.

The basic problem is that a JPEG compressed Image when being opened is decoded to a bitmap array that takes quite a lot more space given that it isn't compressed. 10 1280x720 images can easily take up up to 10 MB even when compressed and can get as big as 50 MB when uncompressed.
That aside your problem most certainly has to do with references to those images being retained in your App (as mentioned by Mcosmin), so the memory is not freed up. You can debug that using the Profiler included with the Windows Phone SDK. There are WebCasts and articles by Microsoft that explain the usage of the tools.

In the Downloadengines I am do it this way!
Downloading the images to an temp file, create an Thumbnail of it, delete the file and download the next!
It works fine.

You can do this a lot faster by using memory streams instead of file streams for temp file to avoid the slower isolated storage.

I am try this in the next version!
Thanks all

Horrible Memory management. Please help.

I love my Windows Phone a lot. Everything about it is just great. Size of the screen, resolution, Music+Videos hub, Office etc etc.
But, there is an issue. A very serious one. Memory Management.
Recently, Nokia launched an exclusive N.O.A.V 3 FREE version for India for a limited time. I couldn't get it, in spite of being in India AND having a WP8. Why? Low Memory.
I wanted Asphalt 7, as it is really low priced (lower than Asphalt 5) but I can't get it. Why? Low Memory.
Tumblr is a great looking app. Lovely Live Tiles, but...BUT, at a cost. Memory.
I have deleted a lot many apps as I don't need them anymore or were just plain bad. But it has left a permanent mark on the OS. It has consumed space which a deleted app should release when deleted. But no. I still see the app name, with the memory consumed. So, those bytes are now rendered useless. Again, the same problem, Memory.
I would really appreciate any help to free those used bytes so that I can get on with my life and get better apps. I am now even scared to the extent I don't download apps I know I won't be using after a while.
What a gorgeous OS, what a great user friendly UI, how beautifully smooth and fast, but all comes down to one very basic and fundamental flaw. Memory.
And no, I am not hard-resetting my phone.

I thought asphalt 7 was available for 512mb devices...

If you're referring to the low RAM of your phone, you may try this,
Thanks,

I... *think* he means storage (not RAM).
I don't know what he means about "It has consumed space which a deleted app should release when deleted. But no. I still see the app name, with the memory consumed"; that part makes no sense. Deleted apps are removed and consume no storage on the phone. It's not even like "normal" Windows where installed programs occasionally don't clean up after themselves; the app manager on WP takes care of all installation and removal, and there's nothing left after it does so.

I was referring to memory and NOT RAM. And sorry, my bad, when I uninstalled the Bloomberg App, I still saw it in the Storage Check app consuming memory. But it isn't there today. I removed the Flikr Wallpaper app and it was gone in no time from the Storage Check app.
But, why isn't my Free Space increasing? It still says 1.5 GB free in spite of many apps removed. Also, there is a very mysterious 'Other' category eating up about 978 MB. And even Temp Files dont go all the way down to zero. If I say 'clear' to Temp Files when it is 500MB, after clearing its 388 MB.
I need to empty some space man.

Have you tried Shrink Storage App, and try to delete the search history.
Addition: IMO, if you are installing a large app and was interrupted and never continued the installation, the portion you initially downloaded remain on your phone. Its hard to remove that file.
FYI, that Other on storage is a windows bug.
Thank you,

"RAM" is Random Access Memory, and is commonly just called memory. If you want to refer to persistent storage, you should generally use another term. NAND (for NAND Flash, the type of storage used in phones), Flash, SSD, HDD (technically inaccurate for a phone but not confusing), or simply "storage" are all good options for what you apparently meant.
Most apps are tiny (less than 5 megs, often under 1 meg) and removing them will not affect your free space noticably. Larger apps should be more visible, though it may take a few minutes for the app manager to finish cleaning up after them. As for "Other", that's mostly stuff like the local email cache (reduce the number of folders you sync and how long you store mail for to reduce this value) and downloaded files and so on.

To be honest I will never buy a phone with less than 16GB storage, 8GB or even 4GB on WP8 is just a joke, Never had this problem with my WP7 Lumia.
The other storage issue is a problem which will hopefully be rectified in an upcoming update, Even with 32 GB on my Lumia I still have nearly 1GB other storage after using Storage Check/Clean up, I believe it is from uploading pics to Sky Drive and of course other temp stuff but it would be great to be able to free this space, Fingers crossed it will get sorted soon

Exactly, less than 8gb WP8 will be useless if other on storage will not be fixed.
Some news says that the other on storage will have an improvement on this coming GDR2 update, I doubt that it will be totally fixed, since they say that its just an improvement.
I think No, I did'nt use skydrive, but the other on storage, grew up to almost 1gb.
History on Internet Explorer/Search also contributes to the growth of the Other on storage, deleting history may free up a 100mb/wk on my WP.
Thank you,

My 521 has 8gb and still has like 3gbs of space left. I have a bunch of games and a couple of albums on the SD card.
