RFS filesystem

Hello I had read about the problem of stalling. In the OCLF thread, I read that this is due to the RFS used.
BTW anyone can verify if this is still the problem in Android 2.2 build.
Thanks.

Still rfs in the leaked froyo builds; no one can verify what the official build will be like, because it hasn't been released yet.

Seems pretty unlikely that samsung would consider a change in fs for the i9000 at this stage in it's development. I think manufacturers like to stick to their own proprietary fs...

This is the 1st and the last time I purchase a Samsung Phone Android, no matter what we do, still crapy slow. I start to hate this phone.... Android is cool but I9000 phone have the best hardware but the software suck....

No device is perfect. Most problems are fixable, I think. If Samsung doesn't do it, I'm sure the talented developers in this forum will do something - that's the beauty of Android..

the voodoo kernel puts the phone to rights. with that fix, its the fastest thing on the market.
it's just a shame only a small minority of users will see the benefit and the phone will ultimately fail because of this.

True that no device is perfect, but for the money we pay to purchase such a device, we expect a product that works out-of-the-box, which is not the case for the Galaxy S.
Compared to the hardware Samsung put into it, its shockingly laggy and other phones in the market with half the hardware specs dont show such lag due to the tweaked software they have
A mobile phone is not just a piece of hardware, its the hardware with its software that enables the optimum use of the hardware and also the accompanying PC software where Samsung has yet failed through the horribel "Kies"
I am a big fan of android, but Samsung has tarnished android through this ****ty product
This will be clearly seen once a pure android 2.2 OS (with no samsung software on top) is available for the SGS with the proper file system and memory manager

There are 2 problems with the phone.
1. File System
2. Memory
File system can be fix by using lag fix. After you implement lag fix, you feel phone is snappy and fast and you start running and install tons of apps.
This started the 2nd problem, even though is 512MB ram, most you get is 200Meg usable, however with some background service it reduces to 130 on average. After few hours of apps used or longer time the available memory can drop down to 30Meg. This is when you feel the 2nd lag. Even with 80Meg ram available you will still feel lag, and swype start behaving funny.
This can only be solve or temp fix (some people say you shouldn't) if you use softwares like ATK, SystemPanel Apps. (Just KILL THEM ALL) when you feel your phone start to slow down and your phone will than be alive!!!
The real fix for the memory issue.. unfortunately.. i believe we need a phone with minimum 6 to 700MB free RAM. Than you should feel the phone responsive all the time until all the apps start clogging up the usable RAM.

I understand where you're coming from, regarding this. However, being somewhat of a tech freak, I am quite happy that so many tweaks have been developed by the experts here in this forum - my Galaxy S works well enough for me, rooted and sped up with the one-click-lagfix app.
My experience so far with Android on the Galaxy S (shortcomings and all) has generally been way better than my previous experiences with S60v5 on the Nokia 5800 and N97.

I haven't had these problems for a long time, actually using a taskkiller makes it slower for me. Since JM* it's not possible anymore to have only 30Megs free as the least low memory killer level starts at around 40 Megs which turns into having 50ish free all the time. The only time i get lags is when installing apps but otherwise never with loads of apps installed. I use the oneclick lagfix btw.

The filesystem choice is not wise from samsung, the hardware and software interaction are because samsung is using Hummingbird processor and that google developed android to improve it on snapdragon because the nexus one is running it and most of the andro phones. So samsung has to "fix" android for their processor.
For the memory "issues" like I said on another topic
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
Linux however isn’t generally affected by this. While I admit that I don’t know the architecture and reason for this… linux will run the same regardless of if you have 20mb free memory or 200mb.

[Q] Available RAM?

I haven't picked one of these up yet, so I'm curious. Could someone check the available RAM after a fresh boot and tell me what it is?
I'm interested to see how much of the 3GB Touchwiz (and associated apps) takes and how much we actually have available to us.

7when I clear the ram it's roughly 2.5GB. tthat's after it closes 23 or so active apps.

Thanks. I'm sure a lot of those apps start right back up. I'm more interested in the available ram after a fresh boot because that will be a more accurate picture of what we have to work with.

I doubt it's all for the system. a lot of that bloatware is probably sucking up a bit too. as well as a few apps that I have running at staert up. 1.4GB is still quite a bit for an android tablet.

It is, I guess. My Nexus 10 sits around 500 free and it tends to refresh a lot, so I guess we still get a lot more overhead on this tablet.
Thanks again for checking.

killed all for ground apps TouchWiz UI uses up 2gb of ram?

So this is pretty crazy and weird but I killed all the apps running in the background and it says I'm using up 2.07gb of Ram how is that possible?

Why does it matter? There is a ton of memory in this phone, and the OS manages it very, very well. You don't need spare memory. This isn't Windows, you won't run out of memory. It stores what it thinks it needs in RAM and keeps it there for quick access. It uses all the memory all the time (or at least it should). One of the things that prevents lag is to have the stuff loaded and ready at a moments notice.
Its a question of how the OS runs, not how much memory its taking. I would prefer if they hid that stat all together, then people would stop fixating on it, and loading efficiency killing memory manager apps.
Much like running defrag on a modern hard drive (they are supposed to be fragmented, they work better and faster that way) Android is supposed to run 90-95% used memory.. ALL THE TIME. Its the way its designed, and it works better that way.

One of the biggest misconceptions on all of XDA is about used RAM in a phone. People are always saying "OMG, there is only 500mb of unused RAM on my phone, it's going to slow down to a crawl!".
Just to be clear and hopefully people will understand it....unused RAM is wasted RAM. It does NOT have anything to do with slowing your phone down or anything like that. If there is 1gb of free RAM on your Note 4, that's totally fine.
Android manages RAM very well, don't stress. That's actually way more than it needs. You can only have 200mb of RAM free and your phone would still run fine. It's the way it's supposed to work. We have more than enough RAM in this phone.
I just hope this misconception will finally go away. I see at least a few RAM threads in every device forum.

It doesn't matter to me it's just the fact that I don't have any apps open and TouchWiz itself uses up 2gb of Ram to me that's a lot js

It truly is a misconception. Android, windows, nix, any OS, for that matter. You would want too see your RAM being utilized. I would prefer to have my RAM used than not used at all because any unused RAM is a wasted RAM. This is also same with CPU. Unutilized cores are wasted cores. When writing software, one of the best practices is to learn how to use the memory to its full potential. You would want necessary stuff in RAM because using them when needed is faster if they are already loaded in memory than reinitializing the modules again and again every time for use. As far as memory location, RAM still provides the fastest. This is why in many companies that used gigabytes of data in their databases, a common practice in databadse engine technology is that they would actually load entire gigabytes of frequently accessed tables in memory for extremely fast access.
In short, don't worry

Thank you for the replies like they say you learn something new everyday. I appreciate the input

I'm more curious to know how the system manages to use more RAM every year with every new device released. Are there really that many more new features every year where they gobble up RAM?

My first computer had 512 mb RAM and it was fine at the time. Of course, with newer releases, they develop more features. With more features, more modules are created to support those features. Hence, more RAM usage.

^Wow, I think my first PC might have had 512 kb of RAM.

That's true but with Kit Kat we were supposed to get a leaner running OS so that it would run on even old devices with minimum RAM. And I don't see how Touchwiz by itself could add 1 GB of RAM usage between the Note 2 and Note 4.

I would disagree on wanting all the ram to be being used... On previous rooted phones I have had (GS2, GS3, GSA4) getting rid of bloatware/useless apps eating up my ram made it much more responsive and fluid when opening new programs while significantly increasing battery life. Seems people just spew the bull**** marketing lines of Google across the internet and expect people to take it as truth. User experience is what is important, and getting rid of the garbage on any android version will make it faster. Not a difficult concept to understand.

I think the goal of debloating should be to reduce the use of cpu by unwanted applications and reducing the amount of RAM taken up by them so that other applications may be cached instead. Whenever I debloat I start with watching applications that load and try to trim of the ones I know I don't need at all. I then move onto greenifying applications that run or cache themselves that I'll rarely use. Never in this process do I try to maximize free memory since doing so means applications that are not cached will take longer to launch. Im not sure if this is the right philosophy but it seems effective to me.

I already have two degrees from a major big 12 university. And do a good amount of IT work for the business I work at. If you think that having your ram eaten up by programs you never use is good practice, maybe you need to re-evaluate the school you got your education. Using your logic our computers should be faster when they are full of **** running in the background... That's asinine. Full AND EFFICIENT utilization of ram is proven practice, not filling up ram full of bloatware.

Well said, I agree. I guess I didn't make the distinction of when freeing up ram being eaten up by crap that will never be opened, What I mean is that cached memory being freed up is then able to be used by apps that I actually use. If over 2gb out of 2.92gb is being used all the time, (with the vast majority being eaten up by bloatware and the rest just being the base OS/UI) then that is not efficient utilization of ram. If you have to kill cached programs constantly and then load the new program you begin using, its going to take longer than having that program already having everything cached. In most times this is only milliseconds difference, but the fluidity of the transition is important to many as it is a significant factor in user experience. Who wants a phone that lags whenever a user input is made?

It is interesting that the vast majority of 2GB of your RAM is being using by bloatware. Between the Touchwiz function for turning off unneeded apps and Android's algorithms for determining what should be kept in memory, I find that "bloatware" apps (i.e., app I don't use) are practically non-existent in RAM...at least for me. That said, even if you still have 0.92 GB free, Android is not likely to decide it needs to kill an existing process to accommodate another program.

No... he's not. Read it again. His point is that programs he doesn't need utilizing ram is bad.
We're playing a game of semantics here. He is working the angle that the original posts saying 'using ram is good' isn't true if it is crap that is using it.
Silly discussion at this point as both sides are correct based on the parameters of their view point.

How much free RAM do you guys have?

Is that normal? How much free RAM do you guys have?

doesn't look like it, but mine is the same. I believe it is the lollipop memory leak issue...so as usual we just have to wait it out

Sucks that just as we are finally seeing 3 Gig of RAM we end up in the same situation as when we had 2Gig ?
I have not upgraded to to 2015 Flagship Standard yet but ...
I was hoping to START at the beginning of Boot Up with about
1.7 -2 GIGs of free RAM for Tasking etc.
I think " upgrading" to Lollipop on many Devices could create more problems than it solves - right ?
And the supposed Wifi Calling and VoLTE are not going to work
because they are Carrier Specific Software which must come directly from your Service Provider.

Free RAM is UNUSED/WASTED RAM! Understand? The more software/applications that are pushed into RAM the better because it is available to do whatever it needs to do without having to go and search for it and place into RAM! If and when you need more RAM for something new, say like opening another application...then Android will move out of RAM whatever is not being used and replace it with the new software. If your phone had 10GB of RAM it would still look nearly full. This is a GOOD thing. It's all still available for use when needed. Remember that RAM is always the fastest part of your phone. Of course the more RAM you have the more applications you can have open at any one time without any lag/stutter. But for now 3GB of RAM is quite good for a cell phone on Android.

Come on... I have Galaxy S4 now (going for S6 today). The S4 comes with 1.8GB usable memory but when it reaches arount 1.5 GB it starts lagging, and by lagging I mean a lot! The fact is that when the device has less RAM it gets laggy and it works better when it has more free memory.
Anyway the higher memory usage is probably of how Lollipop works - it preloads the entire app in the RAM instead of loading it from the flash. It is meant to speed up loading but it takes more memory and I can argue for the effect.

once there are some custom roms, this "issue" will be addressed.
until then, you just have to deal with it

How much free RAM do you have?

Hi everyone,
Been using my G4 for just over a week now and have noticed that the free RAM drops significantly after some use (just a few hours), on average I have about 80% RAM used meaning that I have around 550MB free, now I haven't noticed any slow downs/lags but am just curious, how much free RAM do you have and what kind of user are you? Lets gather some facts. I am a relatively light user, probably have less third party apps than the amount of apps preloaded (Google + LG).
Note: I am running the latest version of LG's stock MM, no root.

Android is dicfrent than windowz android manages ram on its own if it runs low itll clear itself to make room for the new i run about the same. All these task killers waste battery now. Its ok leave it be. Ever since kk adroid handles much better

Yes using RAM in modern Linux systems and in Android means that the operating system pre caches things to actually speed up your device.
You had to went away from the idea of having as much free RAM as possible. Having unused RAM is actually a waste of resources isn't it? Why not using that free resources when not needed? Well and the result is a more or less intelligent handling of RAM usage where you will see high RAM usage.
So if you have less free amount of RAM it means all is fine :laugh: :victory:

I also would like to point that apps like Messenger used around 80mb in my S4 Mini (with 1.5GB) and the same version of the app uses around 150 in this phone. So android is doing its good work using the memory efficiently so you have the best efficiency when switching apps and so.

I was reading this article which pretty much explained everything RAM related. I used to own the OnePlus X which also had 3GB of RAM and with that I had around 1.5GB free, with the G4 I have less than half that . Then again the OPX pretty much ran on AOSP android with is feature-less.

No my device doesn't freeze, I get occasional stutters/lags but these are minor. So it is not really a major issue, I was just curious. It is all about the balance, AOSP=fastest performance but least features, custom UIs=slower performance but much more features, for me the features and UI presentation are most important, I can slightly compromise on performance, AOSP is just plain boring, nothing about the UI appeals to me.
