Plz Explain Android Mutitasking

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.

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.

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.

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".

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.

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.....

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.

It is faster graphic wise pretty much across the board, I suspect RAM is the same, probably more is allocated for system,maybe graphics, but I think it's all academic once you past running benchmarks and start actually using it, don't think you can actually tell the difference in normal use.

You wont notice the difference in daily use but the Exynos one outperforms in everything but the Graphics .

Benefit from 8 GB RAM?

Hey guys,
I wanted to ask if there is a benefit in having 8gb of ram instead of 6? Is it even possible to use that much on a phone?
All I've read till now was that developers could fill it with something but I can't think of anything. So I'm just asking out of curiosity.
I don't want a comparison of the 6 and 8 gig RAM versions of the OP5. It's really just about the 8gigs of RAM.
Thanks in advance

OP5 is so far one of the fastest phone you can ever get. You can't make it lag. I hope I answer even a slight part of your question.

I don't think the phone being fast is related to the amount of RAM.
Apps will eventually start consuming more resources and 8GB RAM will become a necessity in the future.
You can survive with 2 too, but 4 seems to be the standard now; next year 6 and in about 2-3 years 8.

Just depends on how well the phone can manage its own memory. But by default some stuff like mobile games take a lot of ram. Upwards to 400-600mbs of ram for just one app. Maybe just cut down on those or just accept that your device cannot keep everything in memory. Its ok to reload apps that are insanely big.

RAM is the only difference. Multitasking is better on the 8GB model though.

you phone will suffer from low cpu speed before ''needing'' 8gb of ram for 1 single operation.
Having multiple app running in the background makes the experience more fun, but the phone loads app fast enough anyway.
In fact, I'm using greenify, so no need of 8gb.
And a lot of cell phone user will change their phone before it will come slow, or really need 8gb. see pixel2 thread, a lot of people thinking about changing to pixel, what a waste...

more RAM = less loading.
this saves you time because the app stays loaded in RAM (no processing). this saves battery because the processor isn't having to work every time you open it. with 8GB, i almost never close apps.

It is easy to say that the more RAM you have, more the OS will use it, and this will make it more dynamic, therefore faster. But I think this is not perceptible for the user.
I have a 8 GB version and the device gets 5GB RAM to boot up... this would not happen in a 4GB RAM of course but this extra RAM usage do not reflect to more speed in a way you can see it...
The RAM management is more affected actually by the SO itself. I never use more than 7.5 GB RAM but my games never stay in memory for more than a day. I think OOS shuts them down after 24 hours not being used.....
This is a much more technical perception of how the device handle 8GB. I think its more a future proof quality then a advantage in todays processing.
