Why only 338Mb available??

Why the epic has only 338 mb available of ram. I thought it was 512mb
Can I remove all sprint non-sense software with a simple root on stock?

The "missng" ram is the unavailale ram used by the system.
Yes, you can. You'll need root explorer or es file explorer, then remove the apps from /system/app.

Our phone has two RAM chips. One is 384MB and one is 128MB. The 128MB chip is dedicated to the GPU and about 40MB to 50MB of the 384MB is used up by the modem and kernel, I believe.

Heres a ram fix..... Its most noticable by most people on froyo for some reason but not gingerbread however i do notice a slight improvement on gb

+1 on this fix. i tried this earlier today. seems to work fine for me, id suggest it to others as well.

ram after 4.1

After I updated my phone to 4.1 i'm only showing 1.56GB of ram in the task manager app. Has anyone else had this problem?

I did notice that I lost a large chunk of free ram... 4.0.4, I used to consistently have about 1 gig free, now I stay around 500-600 megs free

I've noticed this with any 4.1 rom with touchwiz and bloatware.
It's much better using a custom 4.1 TW rom (bacon!!) with some bloatware removed.

I sent an email to Samsung just now. Let's see what they say.
Anyway, this is def. NOT natural. If you bring up a terminal console and type "free" you will see it state that your phone only has 1.5 gigs of ram.
I'm wondering of project butter is using 500 megs of ram to do the speedup we're seeing...

My take-away is that they did, in fact, use the extra 512megs for a new application that is part of the enhancement. My guess is butter.

Its most likely just the system using that RAM, like pretty much every android phone on the planet

Wow. Big difference. I'm seeing the same.
I never thought 2GB would get so low available so quick.

Who cares, really?
I'd rather have my 2Gb completely filled up as it's most likely just cached applications anyway.
If need be, this memory will be released anyway by Android's garbage collector.
On the other hand, history shows us that every new iteration of Android needs more RAM, so that's kinda expected.
My GS1 only has 512Mb which is more than enough if running Android 2.x (Eclair, Froyo & Gingerbread) but rapidly falls short RAM if running ICS.

free memory is waisted memory for some. I disagree when it comes to devices using a battery. Processes use memory and battery life...
I hate to see apps running in background even when I didn't use them since the last reboot. Self running apps grabbing infos about me suck. If Google dont want to stop these behaviors then its time for a new OS.

You got it wrong.
Cached apps in memory do not actually run.
They are just left there so that they can start more quickly the next time you use them.

RAM has to refresh whether it is used or not. The RAM has no idea if a particular bit is used or not.

The last ICS update also lowered the RAM to 1.59GB. I believe it has to do with how much RAM is assigned to the GPU. It is normal.

I only care because of my past experience: the more apps I load, the more memory gets used, and the slower it runs. I tend to use a log of apps. Memory was a struggle on the ole' Captivate.
I want this phone to perform good for a while.

[Q] RAM less than specs

I apologize if this is stupid and everyone already knows this.
Why is the RAM listed under About Tablet less than the specs for the fire? Is there a way to change the situation so more ram is available?
Thank you.

No, the ROM, as well as the stock ROM, take about 100 MB of RAM to get System Apps and Processes working as well as hardware running. With 400 MB its enough to do multi tasking, so unless you have like 50 MB RAM, there is no problem. You can't add more RAM, that's how it is. On AOSP you can get 140 MB of RAM free which is enough to play 3D Games and no lag.

Is that 100 MB being used for running the OS or is it used as a ram disk? If that's what Android uses for running, then what is eating up the other ~250 MB of RAM?
The only way I've managed to get ~150 MB free RAM is to go through settings and manually stop all the extra processes that I don't want running in the first place. The benefits are short lived, though, as they always seem to respawn themselves.

Try different ROMs and wait for new version from Devs

From my understanding, each ROM utilized ROM diffrently, and the RAM always partial taken by ROM to run the OS. Newer kernel version (my case is 3.0.50+) like near future 3.4 may take fewer RAM then the current version, as Hashcode promised. And as you see with USB, SD and HDD, none of them show the correct storage as factory spec. It is always lower

The 1gig is shared between the gpu and cpu, what you see is whats reserved for the cpu.

100 is for Hardware System and the rest ~100 or so is for Keeping the OS running, if you were to take that away you would get a unresponsive Kindle. I have that in Stock ROM I get about 200MB but you have sacrifice some for Heavier
ROMs like JB

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.
