Plz Explain Android Mutitasking - Galaxy S I9000 General

Can anybody explain how android handle multitasking.How such a famous OS is poor at mutitasking?For example when iam using stock browser with stock music player running in background,iam not able to use other apps like webster dictionary or xda app.Everytime one of the task gets automatically closed..So kindly explain how android os closes apps without permission from user? or before closing why dont android warn user to manually close the task according to piority.I think even symbian can do better multitasking than android.

It's due to low RAM.
When there's low amount of free RAM, android will kill some running apps to free up some.
I don't really know more details, but you can tweak this behavior using RAM scripts or your own lowmemorykiller values.
I think ~1GB of RAM (like SGS2) will be really good for multitasking, but SGS1 RAM is a bit low.

As much as I want to get a SGS2, the battery life on my SGS with a 1650mah battery is too good to pass up right now.
Plus the SGS2 is too big of a form factor for my liking.
Honestly if the SGS released the exact same identical form factor successor with 1gb on board, I would buy it in a heartbeat.
I also have a Motorola Atrix, but I ****ing HATE Qhd! Sure the ram makes this phone much snappier, but the small text is a PITA that is almost a deal breaker for me...

Doesn't the SGS 2 provide a better battery life than SGS without considering the extra battery?
For the Motorola Atrix, can't you try changing the LCD density or even the font size?

In this world of patents and sue sue it's harder to implement new ideas in anything even if it cam from youe own mind you will still have to check it first that is there anyone who has this idea before. i am hoping android will do great in future when pc quality hardware will come into these tiny devices, 2gb of ram quad core processors

Try talon kernel. It uses zram which is compressed virtual ram. You can have a half dozen apps open at once at the cost of brief lags swapping between them. I have listened to music, downloaded a 100mb file and Web surfed without any aap killing!

leaked specs of the Samsung Galaxy S3 say it will allegedly pack a 2GHz quad core into its 9mm metal and glass frame.
I'm getting me one of those when they are out.

Can someone explain to me how memory in Vibrant or Android phones work please.

I'm new to alot of this stuff but one thing that caught my attention with this phone initially was its specs and the fact that it has 512mb. Now one thing I've noticed that has greatly hindered vibrant and android phone performance is memory. It's the achillies heal for droid users. Now my phone is rooted and I have auto memory manager and all is good for the most part. But my question is, if this phone has 512mb of ram, then why is 100-130 shown whenever I go into aam? Also will future phones that come with 1gb of ram really improve performance to the point where we users may not need a task or memory manager????..... just really curious because as much as I love droid and prefer it over the iphone, i don't give it to apples iphone for stability and smooth operating.

It only shows like 300mb or less because the other 100mb is set aside for something.
The more apps you have opened at the same time the more ram will disappeare.
And not that 1gb will improve memory but will allow you to have more apps open without lagging

Understood but let me ask this question. Now I personally am excited for the Galaxy S 2 with its specs. Those specs look promising for those like myself and many others looking for a very smooth operating phone. Gingerbread, 1gb of ram, 1.2 ghz dual core processor etc. Do you think a phone with those specs can promise an almost lag free experience for us droid users?
Sent from my SGH-T959 using XDA App
It should but ... from my experience the rom creators here at xda make the phone smoother than the manufactors. Btw I don't use task killers and my phone is pretty damn smooth!

using a task killer on anything 2.2 or higher is pointless. android does a fine job of managing open applications.

Ram discussion on mobile phones

With most new phones having 1 gig standard now, I see the new LG phone announced will be coming with a crazy 2 gig of ram. I'm no technical pro but isn't that a little overkill for a phone? I've never had an issue with 1 gig on my last few phones, and I know ram isn't all that expensive but it seems to be a marketing ploy to me.
anyway, other opinions or thoughts?

Creating a need is what todays mobile market is about. My point is who actually needs the full power of todays phones, a very small percentage i imagine
--<<<<<***>>>>>--
Would be better if they thought about creating faster 1GB RAM chips instead.
But imagine that you have quad-core 1.5GHz CPU and 8 GB of RAM. That would allow you to use full scale linux OS on your smartphone (I know it is possible now, but it's far from useable)
I'd be more impressed with ddr3 ram.
Sent from my GT-N7000 using xda premium
I would be happy if with increasing all dis horsepower manufactures can focus on increasing the battery backup also.
If MotoRazr Maxx can have 3300 mA battery...NOTE2 should have atleast 5000 mA
The 2GB would definitely be needed if they also increased the max number of tabs in the browser. That alone can eat my 1GB.

I beg to differ I would say its very useable already but yes faster chips would be a much better root, the more bottle necks you can remove the better

Full scale Linux runs perfectly well on much weaker systems. If you're talking about the Linux-on-Android project, the UI is not very responsive because it's not running natively, but through a painfully slow remote desktop thing. The actual processing that's happening behind the scenes is pretty quick and so it's still very useful.
Depends what you are doing.as to how much memory you need, etc.
Screen resolutions are getting bigger, cameras are higher res, etc. it all adds up to more data to hold on to and move around. Having an extra 0.5GB or 1GB can make a huge difference in some cases (e.g. Photo or video editing on-device.)
Also, Android puts apps to sleep rather than closing them down and releasing the resources by default (only properly disposing of them when more resources are required for a foreground app. Having extra RAM means more can be resident in memory without needing to dispose of anything so that could lead to a slicker UI experience and a phone that seems really fast and responsive.
The thing that disappointed me the most about the s3 was the ram, really ruined it for me. Phones today must have 1.5gb atleast.

Indeed once we can get a working native X11 desktop running (There are a few projects working hardo n this so its likely it will happen!) it will feel alot quicker, but if you try using command line applications they feel just as snappy as running on a few years old desktop

What the herr you going to do w/ 1.5GB of Ram? Run Photoshop CS5 and have 50 apps open lol? You don't need it. It would be nice, but it's not necessary.

What I was about to say too.
I'll sometimes have 5 to 6 tabs open whilst using Instagram and Facebook and drawsomething.

will Samsung galaxy S IV have 8 core phones next year?

so the pattern is doubling the number of cores every generations then the next generation should have 8core processor?
I highly doubt it...
Probably a hex core.
Swyped from my OG Droid running CM7
I just noticed this in Tapatalk new posts, and just HAD to answer.
What's the point?
Name one situation where you would even need that.
Samsung needs to work on improving other practical features.
They've always upgraded what makes people fall for their phones, but never anything actually useful.
Years ago, their phone cameras went up in megapixels, but sucked no matter how much megapixels they had. Because megapixels aren't as important as is other more technical camera features. But megapixels are easiest to advertise so they went with those.
Personally I think a single core was enough. Now, phone companies need to work on RAM. They could stuff a lot more RAM in before they need to upgrade the processor.

Doubt it. these apps doesnt even require 8 cores. if any of these phone users require 8 core just to play games, either get a console or a decent pc.
8 core to play Angry birds or Shadowgun...pffftt...
will 8 core make me type faster?
Just Faster Speeds
tbh, I think faster speeds are really the only shift we'll be seeing at least next year for sure, but probably the year after that as well. Although with Windows 8 on ARM on the horizon, perhaps devs may find a way to do some serious mobile computing.
i don't think that 8 core will be useful for a device of 5" or 6"
They will stay at quad core but use the faster A15 architecture.
It's possible they might add some low powered A7 cores in a big.little configuration to improve battery life.
It will also have a next gen Mali gpu. Either Mali 604 or t658.
I'm also expecting it to have 2gb of ram.

I'm not entirely convinced multi-cored phones of any variety are even really getting fully utilized yet :/
I honestly believe cores are more of a marketing gimmick at the moment. I could be wrong, I'm no expert and I don't have the ability to see how well android handles the fine details.. But, there are a lot of factors most people don't even think about when buying phones.. Manufacturers know you're not going to ask "Well what about this 1.5ghz single core processor preforming 4 instructions per clock compared to this dual core phone performing 1.5 instructions per clock?"
Maybe when I go to upgrade my captivate I'll worry about cores more but, at the moment I wouldn't be surprised if dual cores were preforming better than quad cores since they have been out longer and had more time to get optimized in the code.
Dual core phones are already fast enough but seems like phones will start competing with pc in the next few years.
Imo RAM n battery life need to be increased greatly then manufactures should start thinking about future multiple core cpu.
Imagine a hex core cpu n the juice it needs
Yes, RAM!
ya, I definitely think RAM has a place because that's one of the best things about smartphones is the ability to multi-task! So if manufacturers can further cater to that, then I think more cores may follow, especially if we get more TRUE multi-tasking where you have live apps running. Because then, you can delegate individual cores to individual apps that are running. ATM I'm not entirely sure why I would need multiple live apps running simultaneously on a phone, however I think for business workers/students it could be helpful to be watching a live stream or doing a conference call while taking notes in an office suite app.

LOL coming from somebody using even lesser hardware than mine. Pull out the wallet and get sum 6 core goodness you cheapo. You even fail at trolling, come on you can do better than this.
On a more serious note, even Win7 has issues handling more than 6 cores efficiently, so why would anyone even bother having 8 effing cores on a phone. A full desktop experience would be useless anyway on something like a phone, only no life nerds should get all excited about something like that. I wonder why people can't just enjoy the current technology, looking so far just means that one hasn't really got **** to do all day IMHO.

I use even lesser lesser lesser, and lesser hardware
Instead of wasting money (which I don't have) on a newer phone, I work on optimizing Android to run at its best on my phone. Look at the Sony PSP. The XMB is amazing for a 333mhz processor. (And its actually clocked at 222mhz at the XMB). Now, were not talking about the browser here, that sucks. Sony spent time on the OS itself. They won't get thanked for it by the people who look at the features list on the box, but they engineered a wonderful OS for such a weak device.

Hehe, I know what you mean...a year ago I had a Desire, and it was amazing to see how greatly the software could work after some tweaking, compared to stock. Sure it was kinda challenging, but it really felt like it was worth it: that phone was a living thing to me, I could hear it breathing. I swear I almost cried when I sold it, and I actually immediately regretted doing it, but it was too late. It was like leaving a dog on the side of the road or something like that, but at that time I was all excited about the fresh dual core thing, so I couldn't think rationally. There are days when I still feel very guilty about what I did. I'll never do that again. Guys seriously, if you have an old Android device with you don't sell it, you will regret it. Maybe not now, and not even in a few months, but you definitely will, trust me, especially if you've been living with it for a while (I had that phone for over a year).
Selling the GS2 didn't actually make me feel that way, probably because I've only kept it for a few months and didn't really tweak it that much...
8 cores is long way to go.
no way 8 core phone in next 3 years!

Using RAM is not bad; needing RAM is bad. Android 4.0 can easily run with less than 400 MB, but some things can be a little faster when they don't have to constantly reload.

This. Everything switches back instantly!!
One of the most frustrating parts of the HTC OneX for me was when i was reading a long page of comments on sites like the verge or typing up a forum post. If i left the browser to reply to a text or facebook notification, and then returned to the browser it would always reload a page, and at the top.
Even the (heavy) Sense 4 launcher would have to load up every now and then.

i wasn't making fun of android, i was making fun of touchwiz. too much bloat.
If the RAM will mean Nova Launcher wont reload itself as much as it currently does on my Incredible, then that's reason enough for me.
Having had the 1X for a month the 2 gb ram was one of the reasons I switched.
The 2GB of ram (and LTE) has been excessively downplayed by the International crowd because..well..they don't have it. The fact is the 2GB of ram should allow a stock phone to reload things much less. If you want to look forward 6 months to a year, I think the difference will be potentially much larger when we start to see creative devs tweaking their kernels to really use this extra ram. This is a ground breaking hardware move. We haven't even really begun to see what is possible. Judging any of these based on stock software at release is pointless. Think about how much better other phones have gotten after a few OTA updates....this device, especially with the extra ram is really well equipped for a long time.

By the time any phone will actually use 2gb of ram, im sure most of us will have moved on to a new phone already. Of course having the extra ram is good for bragging rights, but does it actually mean anything? I'll say no, but im sure some will argue that.

The extra ram in the S3 is there to offset the loss of quadcore....its a nice helping hand to the Krait chip but not necessary for everyday multitasking that the average person does.....I don't know what phones alot of you guys are coming from but from the sounds of these posts they were serious under achievers.

i think the reason you never saw your device running out of room is likely because the system knew how much memory it had to work with and was always adjusting things to accommodate as much memory....if the system had more memory available to it it can behave differently....it's not about "how many apps one needs in a suspended state", it's about "the more apps you can keep in a suspended state the quicker the apps will run for the user"
i know this isn't x86 and it's not windows, but the analogy still stands, consider Windows 7
if you build a pc using it with 2Gb of ram it will run just fine, it will use somewhere around 1Gb of ram sitting idle, using it for the prefetch cache to be ready to launch your most used apps while maintaining a safe amount of memory for sudden useage/overhead
if you upgrade that same pc to 4Gb of ram, it will use close to 2Gb at idle.....it's not quite linear as that but you can see a direct correlation between available memory and memory utilization
the Linux kernel behind android appears to work very similarly, it will keep the most called upon code in local memory so that it launches faster when next called upon. the more memory available to the kernel, the less time it can spend killing apps in order to maintain that same level of free memory for the unexpected execution of a new app
the more memory it has, if it is written/compiled to take advantage of it, the more potential for performance is there.
I would say the 2Gb of memory is more easily utilized than the additional redundant cores in the Exynos kit. I have been looking for some real data on Android and SMP but I know recently Intel made a rare public statement about how it is not ready for even dual core utilization. I don't think Intel would make such a specific claim without data. I don't think the Exynos users are really getting much good at all from the four cores other than synthetic benchmark scores and I think they could see more benefits down the road from more memory than redundant A9 older technology additional cores.
disclaimer: I am still learning about all this so if some smart guy comes along and sees something above that is not quite right....it's not because I am making this up....it's what I understand to be true based on reading.

I have been looking for some real data on Android and SMP but I know recently Intel made a rare public statement about how it is not ready for even dual core utilization. I don't think Intel would make such a specific claim without data. I don't think the Exynos users are really getting much good at all from the four cores other than synthetic benchmark scores and I think they could see more benefits down the road from more memory than redundant A9 older technology additional cores.
disclaimer: I am still learning about all this so if some smart guy comes along and sees something above that is not quite right....it's not because I am making this up....it's what I understand to be true based on reading.

You are pretty spot on for the most part....but the difference here lies in the amount of ram needed to cache applications and perform extended tasks.....the reason my GSII never runs out of memory is because it has plenty for any array of tasks. While caching 8 applications I use all day...and still have anywhere from 325 to 400 megs available for any other array tasks .....I just can't see where I would need more.
As for your earlier mention of custom roms.....this becomes even less necessary ....right now a stock GS3 is using over a gig.....that's because its loaded chock full O'carrier BS on top of all samsungs layers of bloat and BS "features"....you strip all that crap out and you have a 275mb OS and more ram than you will know what to do with.
Bloat is the only thing requiring this extra ram because its running at system level which is also why Sense stuffed a dagger in the H1X.
Performance for launching is helped greatly by the processor for anything not in ram and the threshold for my phone is 64mb....which means my phone will not start killing of apps until that's met.....I could not seem to hit it just messing around.

right on, yeah i agree it's overkill right now. I just think within the next two years, we will easily see multiple areas where having more is better than having less. I am thinking way outside the box but I am seeing visions of custom kernels that are doing some extreme caching, even running a VM type environment.....actually I am thinking of running Android and perhaps there will be an opportunity to run Windows RT or some desktop version of Linux simultaneously......something a device with even four cores and 1GB of ram would have a hard time doing.....and that's not to say it would run well on the S4 US version either, but it is certainly more suited for it

You are partially right. My sensation xl and my friends galaxy note works multitask pretty well with just 768mb and 1GB ram. But that was on Gingerbread. Once we upgraded to ICS multitasking suffers tremendously. He even blamed me for persuading him to do the update. For GB 1GB is enough. For ICS 1GB is not enough if you want the best multitasking experience.

I have to blame both device and OS....I am running ICS on my GS2 and have not even seen the slightest difference.....although my battery is just slightly worse.

You must be running some early leeks cause some of my phones like the GS2 and the evo 3d are running ICS flawlessly.

Note 2 JB VS S3 JB. My observation

-Overall, it's smooth but S3 is smooth too. No one can differentiate.
-The extra ripple effect when you release your hand while in the lockscreen is not present. This means that, that ripple effect that users have accustomed to in ICS will not be present in JB rom. Damn you Samsung!
-2GB of Ram equals extreme multitasking. No need to uninstall bloatwares.
-Smart rotation. a feature that can be easily enabled in S3 JB rom.
-Quick glance. while the phone's screen is turned off, user can put their hand in front of the top of the phone to summon notification for missed calls, and messages. I think this is useless.
-Multi Window. This is really a useful feature. Samfirmware tweeted that S3 will get it as well, but I'm not holding my breath. Samsung could say that S3 screen is not optimized for this feature or other ridiculous reason.
-There is no widget for "direct call, smart stay, voice cmd and S beam". this is really weird because S3 have it
So far, after trying Note 2 for a few minutes, I still love my S3. The reason is really simple, Note 2 is too large to be used as a phone. S3 is already pushing the limit, at least for me.

2Gb of ram is definitely equivalent to extreme multitasking. All those people who said "unused ram is wasted ram" despite my many attempts to explain how processors work, irrespective of the linux kernel, can't say anything about this now.
Anyway, multi-window is the only feature that I really want, but I doubt we'll get it.

Unused ram IS wasted ram.
Nobody said that more ram isn't better, but empty ram is useless to you.
Ram uses the same amount of power whether it is full or empty.
Having full ram means more programs loaded and ready to go, less clock cycles, more efficient system.
you could have 1TB of ram, but if there is only 600mb of stuff in it, its a waste.
So, unused ram is wasted ram.

Flipside of that is that most of us never argued that unused ram is wasted ram as to power cosumption, but that it should be our ram to waste and that i9300 is seriously lacking in multitasking department when stock, because of lack of free ram not even rivaling sgs2.
Or how easy it is to load slim rom, posting screenshots of freshly reset firmware without third party apps, or screen of ram usage before all the services are loaded, or screen of freshly cleared ram, none of which are representative of real world usage.
As I recall the original thread, that mantra has always been spoken in a way strongly hinting like we got plenty and don't need more, now just adding "we never said more is not better".

Nobody ever said less ram is better than more, at least not that I know of.
If they did they were talking sh*t.
I'm speaking from a factual point of view, not a butthurt, trying to defend my purchase point of view.
I would love if the i9300 got 2gb of ram.

I am not targeting specifically you, as I know from your posts you're pretty even handed and factual person.
Referring to the whole discussion at the time of release of the phone when we found out nam versions are coming with 2gb of ram.

Ya we got a raw deal when it came to ram.
But that's touchwizs fault, my nexus 7 has 'only' 1gb of ram and it multitasks like a boss.
Samsung screwed the pooch when they put tw on a phone with 1gb of ram.
The S3 isn't the phone it should have been, it should have had an exynos 5 CPU and 2gb of ram.
From now on I won't buy anything Samsung because vanilla android just runs so much better than skinned versions and it isn't ugly anymore.
Plus the 4.1.1 update hasn't dropped for everyone yet and my gnex and N7 are on 4.1.2 for over a week.
With 4.2 probably being announced on the 29th I think the S3 won't ever see it.

Not exactly. If you have less than 100mb of free ram, when you start an app, the processor has to close several background processes in order for the app to start and work properly. This causes a momentary lag. Similarly, if you minimise an graphics intensive game to read your messages, the game is closed to obtain more ram.

That applies if you have too little ram, and I agree too little ram is not good.
My point is if you have ram and it isn't being used then it is wasted ram.
Ram is supposed to be utilised.

Well Even with the Mods and tweaks available right now, It is more smooth and fluid then my BEST setup I had with the I9300. So I think about it like this. Everyone is trying to find the rom which makes there phone run beautifully. Well I already have the setup . And anything that comes now is going to be a bonus. It really has only been a few weeks since a few of the devs got there hands on the devices, and I think we are moving quite nicely. Soon we will have enough dev support to make us all happy. Soon as someone starts porting roms or Creating thats when the fun really begins. We already have 3 Roms which are Basic but its still a start And I can wait as the way my phone feels right now Is absolute butterness < if thats even a word
Note2 jb no lag but think maybe due to 2gm ram

If you have free ram then it will be reserved for more apps to be loaded which means more rams you have then more apps can be run smoothly so I wouldn't say its wasted ram. More rams you have then More apps can be loaded and stay on background and process smoothly by users input.

In my opinion more ram is more good for our devices because yes ram does run the applications and removes a lot of lag.....I have i9300 but I am very angry that why Samsung just releases their s3 new version and broke the trust of old s3 users.....

Can you not read what I said?
You are basically saying what I said, more ram is better.
Un-utilised ram, is wasted.
What is so hard to understand about this concept.

Yes I read it already but if there is more ram the more apps u can open at a single time example when ever u open ur dailer first time it takes 3 seconds to open which feels so much annoying at some times but if u have More ram then the dailer would be covered by extra ram until u use a lot of apps together...

In my experience, keeping the ram free is better. Your phone/tablet is smoother and faster. And there is a logical explanation for that. The OS is loading in background data from applications. If you use one of those applications, yes, it will launch faster. But if not, room has to be made, so in fact you have to wait more then.
You don't save anything by letting the apps load to full ram. In fact, you consume more resources like this, because you can have loaded apps that you don't really need/use any time soon.
It's just a gimmick. Let's load some apps, when the phone is idle, based on what ever criteria so when the user is actually launching that app, he will have the impression that the phone is faster. But your are depending on the accuracy of that criteria.
Limiting the number of background processes works wonders for me. Maybe not so much for my S3, but for other lesser devices it's very obvious.

Nonsense.
Ask anybody that knows anything about computer systems and they will tell you it is better to have a program in ram waiting to be used.
It DOES load faster, it is the basis of all os's today.
It gives the impression that it loads faster because it does load faster.
No you don't consume more resources like that, by keeping apps open in ram you cut down on clock cycles associated with opening that app every time you want to use it, yes sometimes apps are dumped out of ram but that is because the system needs more ram for a bigger app and bumps out whatever it seems necessary because of oom settings.
Limiting background processes beyond a certain point means you are losing efficiency, battery and performance.
Fact.
