Hey so I just bought a used Verizon Galaxy 10.1 and noticed things got pretty slow after a day of use (not rooted) so I went looking into what might be going on. I assumed it was a memory thing and when I did a "cat /proc/meminfo" I was surprised to see only 740912 kb reported for MemTotal. Aren't these devices supposed to have 1GB not 741mb?
Does anyone else see the same number?
think it might not even report the ammount of ram that android itself takes up, but dunno.
In taskmanager there is 723 MB of RAM.
My task manager reports 724M RAM.
Maybe the rest is reserved ?
The rest of the RAM is dedicated to the GPU.

Perfect, thanks for answering. I had a feeling something like that might be going on but wanted to verify.
I think I need to ditch my verizon version and get a wifi only. I want to root this but there's way more development going on for wifi only version.
Yeah the Wi-Fi model is miles ahead in xda support. Roms themes etc.

So I noticed that the lte shows less ram then the 3D anyone know why this is? Thought lte had more

If it is like in the computer world I would guess more of it is going to the GPU or other components in the phone.

Though it says that there is so much of the RAM being "used" in reality only a portion is actually being used. There are many programs that are dormit in memory waiting for you to execute them, by remaining dormit in memory they can run much faster, its in a way caching.
Now if you want to control that, download AutoKiller Memory from the Play Store (https://play.google.com/store/apps/...t=W251bGwsMSwyLDEsImNvbS5ycy5hdXRva2lsbGVyIl0.) and you can adjust the way the Kernel manages the dormit apps and free physical memory. Please read the help and the Dev's website for more understanding of the tool and the way Android manages the RAM.
Yeah, it's probably allotted for something else.
I noticed this with the Sense 4 ROMS for the 3D. All of a sudden had like 200mb total of missing RAM by flashing the ROM.
I just upgraded to EVO LTE and is very nice its fast quick beautiful screen very smooth but can't figure out what's is using my ram I'm using 400 and have mabe 270 left to used but when I combine those it doesnt equal 1gb of ram

htc sense use ram also i don't know how much but it's alot. Don't worry about the ram cause the system will end whatever you have open and not using to make more ram.

I think the gpu probably uses some too which might be why it didn't add up to 1024mb

Possibly, but when I add my used and unused ram together I only come up with
660 which is way short or 1gb ram

I think I remember the EVO 3d with more ram. Like 720 something.
Well, there are plenty of hidden system settings. The number that you see in Task Manager or Settings is how much RAM that can be used for anything. The ram you do not see available is being used by things that are UNABLE to be removed from RAM because they are essential to the system running. That is the reason why we see nothing close to 1GB.same thing goes for computers, you can either see Installed Memory or you can see Usable Memory. Installed Memory on LTevo would be 1GB and Usable Memory on Stock would be around 670MB(IIRC) for me.

I noticed this also, coming from the EVO 3d (also with 1gb of ram) vs the 4gLTE. IIRC the 3d shows 804mb total vs 680mb. I figured it had to do with the 3d running gingerbread/sense 3.5 vs the 4gLTE running ICS/sense 4.0. My friend who has a galaxy nexus also with 1gb of ram, shows around the same amount of ram in the task manager.. either way I am absolutely amazed with this phone, not one issue or hiccup so far..
I see many people on xda posting ridiculous methods of freeing up Ram and frying the phone
I was once one of them, but its too much nuisance to tolerate when its again and again repeated, I found this very cool thread for noobs:

This is the placebo effect, you see more free RAM (oooh a high number !!!) and you think it is better so you feel it's better.

Thanks for post. Many users don't know this
I'm waiting for someone to come in to this thread and try to tell us why you need 50 gigs of Ram and how his US variant with 2 gigs of RAM is far superior to the international, I own both so before this even comes to light lets be clear,clean,cut and dry the international version is smoother than the US variant no matter how many of you RAM fanatics want to tell me that 2 gigs is master race. Further Android manages RAM very well on it's own you can probably run just about anything with 512mb of RAM, but a whole gigabyte that's just butter on my toast. I hope people will actually read this thread and learn how their devices work instead of just yelling about how they need more RAM and wonder why they have no battery life when a task manager constantly clears the cache. I would appreciate it if one of the more informed members of XDA can make a simple write up of how Android manages RAM and why more free RAM is not always better :highfive:
Whilst I agree with the comments here it sometimes helps by not being rude to people who aren't as knowledgeable with android as some of us and who are asking questions like I have seen in some threads.
Whilst the adage free RAM is wasted RAM is generally correct with android there is no harm in freezing of uninstalling apps that you know you don't use.
For example I never use svoice and chat-on so there is no harm in freezing those or preventing them from loading if they will never be used.
Whilst unused RAM IS wasted RAM,,, RAM used by unused apps is also wasted ram
Go easy on the noobs and have a good weekend.

I was cursing sammy for not providing 2 gigs in s3 (int)but now it seems fine. But since ram is cheaper what in the world would had hapnd if sammy had provided 2 gigs.

If I'm not mistaken the architecture of the version supporting HSPA does not support 2gb, that's why the Korean variant is slightly different and has 2 gigs of RAM, essentially It wouldn't have made any difference, the 32nm a9 process is about as far as it's going to go. (also I think the Korean version has 2 gigs of Ram due to LTE taking up more resources)
op, maybe it is not the issue of free-ing up RAM.. it also save up some battery...
eg: before you went to slp... make sure all are shut down.. and hv a minimal prog open for sync/phone..
of course now all OS have RAM optimism, but then sometime/some of the OS are not so profession on this.
most of the time due to the OS rooted/JB, which will have different methodology for optimizing the RAM.
Well, you can't deny the fact that more ram equals better multitasking. With less than 200mb of free ram after several days of use, my browser has to reload whenever I minimise it to check messages. But that wouldn't be the case if I had more free ram, ie when I've just rebooted the phone.

If more RAM doesn't matter, then why do I get booted out of Tintin and other heavy gameloft games whilst having had to run other program before the games were started? The only way to play without the game crashing is first be clearing cache. Would it be low RAM, Samsung's fault(no good optimizations), or gameloft's fault(no good optimizations)?

I'm just saying having more ram would make the gs3 more future proof especially when games and apps get bigger and better and more resource hungry, plus ram is cheap and it wouldn't hurt adding 1 more gb......

Hello
I just got the LG Optimus G AT&T, I thought the specification for phone memory is 16 GB, but it only has about 11 GB available to start with?
Is that correct? Just want to confirm.
Thank you,

The system partition is 1.4GBs alone but there are a couple of other partitions that vary in size. A lot of the reserved space is unused.

Can it be reclaimed or do you know if there is a valid reason for the unused, reserved space? Thanks in advance for your feedback.

Not sure. I guess technically speaking Yes is could be reclaimed but I doubt it would happen. When CM 10 came out for the Captivate they kept tweaking the partition layout because at first they allowed too much space and then they changed it again to allow less space. The big problem is when they kept changing it, it would wipe the whole device including internal SD. We may see a new partition layout when CM 10.1 comes out but again I doubt it. If you download SD Maid and click Advanced on the first screen you can see a list of locations and the allotted storage for each (see screenshot).

Depends on what you install. Mine was like 9 gigs.
The storage device won't have 16GB of space anyway, not after it's formatted. You get 14.7GB. Then the stock ROM is about 1.2GB -- before installing it on the drive. The OS gets a partition of several gigabytes to reserve space and keep knuckleheads from stuffing the drive with crap.
The AT&T version comes with a blank 16GB SD card pre-installed, in addition to the 16GB of internal storage. If that's not enough space, you can buy a 64GB SD card separately.
Is that the biggest memory card you can use in OG, 64GB?
yep. havent tried a 128gb one (if they exist) but with 64gb it works fine and it's the max specified in specs.

o_o; Do people really need all that space..? I think the ~27-32 is fantastic. Hell, I was fine with 8 on my Inspire 4g. Now people are talking about 128gb? Ya'll are nuts..
Be glad you get that much. the AT&T One X only had 9.7 GB free out of the box. HTC/AT&T used up almost HALF of the storage.
