Android RAM Management

Hi,

I read about the Android RAM Management a lot, and I know that theoretically unused RAM is wasted RAM and that Android pre load common used application to the memory in order to optimize its perormance.

On the other hand, when ever I start filling that phone is has performance symptoms such as 'slow keyboard loading' or 'long time from the time I press the home key till it actually show the desktop', I just know that the used RAM is around 720 out of existing 830 and that I should close all open application (some times it is only one or two background applications).

Is it normal?

What can I do in order to optimize the performance?

Thanks
Yaron
 
Thanks for your answer. Nevertheless, according to many articles that I read about Android and it's memory management, they all recommended not to run any tool that kill the background processes.

My question is more like wondering why the above behavior occurs.
 
Beats me mate, i didnt think id have to use the widgit on s3 but hey.
yeah your right. Task killers are very bad. This widget doesnt stop any process, it just emptys the cache your apps have built up. Try it. Dont have it set up to clear automaticly, just have the widget on homescreen and when say the keyboard gets laggy, check the widget and itl have turned red. Tap it and see the difference
 
Thanks man :-)
This is exactly my question here. Why such enhanced phone needs my manual help to optimize it's performance?
There is no build OS configuration that can be use to change the phone behavior?
 
It's true, unused ram is wasted. However, the S3 is known for its poor RAM management, Samsung really broke something there. 1GB of RAM should be just about enough, but not with the S3. On the latest leak, even Samsung is trying to improve the situation with zRam, apparently.
 
A lot of it could be down to poorly optimised apps too i suppose. I totally understand why cache is a good thing but surely apps, or even your OS should "know" when things are getting that laggy way and, maybe not clear the cache automaticly but present a notification with the option?
If it cleared automaticly that would be bad because for example, youll hit BACK on the browser and the previous page wont be there.
hope someone more technical can give a better explanation :beer:

Im using Zram at the minute and tbh it seems to perform miracles with multitasking esp redraw issues :smokingsomb:
 
Let's hope that the next build will bring some news with it.
By the way, if all android phones are using the same android base, how come only Samsung suffering from such poor performance?
 
The base is the same, but Samsung adds tons of customisations on top of it, and changes many stock values of Android. It's very likely they messed something up while "TW-ing" the firmware. AOSP Android is much faster and responsive.

It would be the same as a PC. The PC need manual cleaning every once in a while.

Touchwiz is so far from the base now. If you just look at the size of the operating system... Aosp (google android) based roms are like 120-130mb. Touchwiz roms are over 800mb
 
Totally. Touchwiz is a mega-bloated rom. I was playing with my neices stock s3 tonight and it feels completely different to mine which is runnin an AOKP rom.They really should make it more app-based so that people can pick and choose which features they want/need. Like an Aroma Mod but more simple for the average user :thumbup:

Rxpert83,

Can you point to a thread, guide or link on how to teak the memory usage if rooted?

Thanks!

If your phone is rooted ?
You should try "Andromizer" from the app store.
(Is a new but safe app with common tweaks from xda)
One of the options in the app is the "one-touch-optimization".
That gives you different optional tweaks that you can apply to your phone.
For me I found the right balance after using only 3 tweaks.

*SD tweak
*VM tweak
*Memory tweak

I hope this can be of any use to you.
