Interesting bug....involving the RAM

I didn't notice this in my first 16GB Tab, but on the 32GB tab, if I open the Task Manager through the minibar, it shows 775 MB total ram I know we are supposed to have 1GB ram, so I figure the 225MB missing is due to god knows what, that's not an issue.
If you go to Settings, Applications, Running Applications, it shows you have only 512 MB ram......the real question is, which one is it?

I also noticed that in the 16gb, but ignored it since the usage of ram in the ram manager exceeds 512mb. What's bothering me is why do the usage of ram differ between the ram manager and the one in running applications.

This was the first thing I noticed when I turned on my 7.0 plus for the first time when I got it on Christmas day. I just disregarded it but I am happy I am not the only one who is curious as to why it is saying 775 MB of ram.

If you take a look at /proc/meminfo you can see the kernel only recognizes 775 MB of memory. Guess that explains why it felt like apps were closing more frequently than on my 1 GB phone.
Question is, why are we getting less than memory than was advertised?

On mine:
Code:
# cat /proc/meminfo
MemTotal: 794900 kB
We are getting all the memory "adverstised", but you have to remember that things like the kernel itself and certain other things take memory before hand. The same thing happens on android phones.

Well wouldn't that still show it as being "used" so to speak out of the total 1GB or 1024 MB? Or does the kernal just allocate itself and then let everything else take over from there?

I honestly don't remember. I wouldn't be concerned, however, about the lower number. It's perfectly normal on the few android devices I have.

could it be that some of the ram preserved for the GPU?

Ah... Never thought of that, but at the same time (IMHO) I think it's unlikely it would use THAT much.
Though I guess if other android devices do it according to garyd it's nothing we should worry about.

I believe it's RAM reserved for GPU and a few other things, like the Samsung MFC and camera interface.
On Captivate, some of the "speedmod" kernels changed the reserved memory sizes to free up user RAM - but often reducing the reserved memory can break stuff. (For example, trying to port those changes to Infuse caused the camera to stop working, along with video decoding acceleration.)

Keep in mind this is the Linux kernel plus android.
In this case the system shows how much memory is available after the Linux kernel and android overlay are loaded. the galaxy 7 plus has 1GB of ram.
Now if this was straight Linux without android you would see the full amount of ram listed.

GT-P3110 8gb shows me 4.5 gb ??

Hi guys got my device a week ago,flashed it with CM9 and its still showing me 4.5 gb instead of the 8gb
I paid for.
Is there a solution to fix this?

That's normal. Should say you get whatever is left from the 8GB when we are finished.

Where does that 4gb been used then? Rom itself is around 150mb
Sent from my GT-P3110 using xda app-developers app

Even i am baffled with this. My P3100 is supposed to have 16GB but actually it is 11.89GB only. It is misrepresentation on Samsung part. They are cheating customers. User storage means pure user available storage.

I feel ripped of by this 8gb is nog much so 4.5 gigs is Just dissapointing...

May be we all should collectively complaint to Samsung. Afterall we paid for it.

that 8 GB is used for your rom, cache, apps(pre-installed and user apps), app data, and whatever you put in your /mnt/sdcard folder.
and you already lose some space in the math. (no 8GB storage device is ever 8GB)

Then companies need to either tell Customers honestly that they will get only 4.5GB or put 12.5GB to give promised 8GB to customers. Why misrepresentation ? It amounts to cheating, technically.

It's the same when you purchase a laptop with Windows preloaded . The catalog says that you have 120GB harddisk storage and 4GB system memory. But when you open your laptop and check the system information, you only have 120x1000MB/1024MB = 117GB and 20GB reserved by Win7 & NTFS default allocation size. And 512MB system memory reserved by VGA.... This is exactly the current presentation for any device.

@cfygeorge
Thanks for valuable info but what this Xx1000/1024 calculation is?
But RAM is still just 678mb out of said 1gb
Tab 2 P3100

I total agree with your logic, but On the Spec page Samsung does state 8gb User Memory. It doesn't say system memory.
I really wish they wouldn't use the memory term, It's storage not memory.
Dang IT!

Dead simple. Hardware manifacturers usually calculate 1 GB as 1000 MB. That's not correct as 1GB is 1024 MB.
About RAM: There is 1 GB on board. Some of it is reserved for OS operations and some is reserved for the GPU. So user RAM is 678 MB. We has this RAM discussions ever since the HD2 :laugh:

Oh...me ignorant child...
I never knew RAM too can be reserved.
Thanks for info
---------- Post added at 04:46 PM ---------- Previous post was at 04:42 PM ----------
Now I even strongly believe manufacturers (Samsung in this case) should give net figures available to the user like 12gb of Storage and 678mb of user available RAM.
Current arrangement is not acceptable. Will write to Samsung for sure.

The thing is i flashed it from original to cm9 because i thougt custom roms are faster,use less storage,..it is faster but 4.5 GB is nothing most smartphones have more space then this tablet. There must be a way to increase the storage or this device should not be on the market imo or at least for half price so we Get what we pay for.

this guy had the same issue as me with the storage and he sais he got rid of the bloatware and now he has the 8gb he paid for.
is it not possible to wipe the whole tablet and flash it with cm9 so i have more storage space then i do now?

[Q] Inbuild Memory

Hi,
I recently purchased Samsung Galaxy SII Plus. As per the site, it comes with 8GB inbuilt memory. When I received the phone, it shows only 3.9 GB total space and 3.56 GB space available. When I contacted the seller, they told me that its Android system which is occupying the remaining space. I am not aware if this is the right reason. Does anyone know about it?

It's normal... All Android OEMs lie about the storage space.
For example the HTC One S 16GB comes with 9.3GB which seems a lot more like 8GB to me.

Yeah, I thought it meant 8 GB available to user too, not 8 GB in total including system files. Thanks to my SD card though, I still have 2.7 GB of internal memory free.
Why is the /cache partition 1 GB though, seems a little overkill?

its almost the same for all device(my old ace says it have 512mb,when only bout 180 is available to me). There are no other internal memory stuff inside your phone,so whatever system will definitely eat some of your internal memory.Even laptop manufacturer are the same(320gb only 280 available),what u expect them to say? Sigh,i dont understand why people only make a fuss bout it now,does everyone start using smartphone only after 2013?

Well people need more and more space andOS need more and more space and phone memory isn't increasing dramatically.

When I go to Antutu or Ram Booster they say I only have 1794 mb of ram what happen to the other 250 mb?

As far as I know, at least for all devices I owned, it's always the same thing (some devices with 1Gb RAM had something like 768 Mb available stock)...
There is absolutely nothing wrong with the available RAM detected from Antutu or RAM Booster or another apps.

It is like that for absolutely everything. PCs/Notebooks, Tablets, Phones, etc. It's normal.

Just remember one thing that with a build.prop edit (by adding a line) you can fake the available RAM in Settings/About phone (like you can show some CPU info), but I don't know if some apps detect it (I think but... not sure ).
Maybe something like "ro.product.************" .
Maybe a Google search will give you the trick, just a cosmetic thing since the real available RAM is "hardcoded"

Yes, but those are dedicated "add-on" cards and are generally limited to PCs and gaming notebooks. The OS would still be using the main system memory. If you had 16GB RAM, the OS and any other processes would be using it regardless. You would never have 16GB available to you. Also, even if you had dedicated memory on the graphics card some of it will also be used regardless without your knowledge.
Any SoC uses the systems main memory.
If you want the full 2GB available to you, have fun never turning on your phone. If you want 2GB only for you, then the system has nothing to run on.
Memory is there to be used. Having a separate section for the OS and 2GB only for your choosing is pointless and inefficient.

I think what the OP is trying to ask is why is the hardware only detecting 1794mb of total actual RAM? Not how much ram the OS utilizes.

I don't have a problem (well I do but not as much) with the OS and GPU use the 2GB of ram I have available but it should be something like like 300mb out of 2048mb (300/2048) of available ram not just cut my 2Gb of ram to 1794. What if the OS only needs 200 I still would not have 1894mb my max available ram is always 1794.

its not out of 2048MB for one
its 2GiB, not 2GB
from wikipedia
Although most manufacturers of hard disk drives and flash-memory disk devicesdefine 1 gigabyte as 1000000000bytes, software like Microsoft Windows reports size in gigabytes by dividing the total capacity in bytes by 1073741824 (230 = 1 gibibyte), while still reporting the result with the symbol "GB". This practice causes confusion, as a hard disk with an advertised capacity of, for example, "400 GB" (meaning 400000000000bytes) might be reported by the operating system as only "372 GB" (meaning 372 GiB). Other software, like Mac OS X 10.6[5] and some components of the Linux kernel[6] measure using the decimal units. The JEDEC memory standards uses the IEEE 100 nomenclatures which defines a gigabyte as 1073741824bytes (or 230 bytes).

2 GiB is 1024x1024x1024. HDD / MMC / SSD use GB (1000x1000x1000) not GiB, however this is for storage. RAM is usually binary 1024... so it most likely is out of 2048.

Oh, well don't worry, you have 2GB RAM. It might just be the way it is displayed in Antutu. CPU-Z displays the total amount of RAM as 1855MB. Not exactly consistent between programs.

I will just try to ignore this and I will be happier I guess, my cpu-z still says 1794MB total ram.

The device has 2GB of RAM but you the "BIOS" or whatever controller is in there allocates some for itself and the hardware in the phone (mainly GPU) and the rest is left to the OS.
Sharing RAM is good in general but many systems require X amount of RAM whether it's actively being used or not as it's designed to be able to use it. if it were to call on that memory address and it's full the system would crash (or a STOP error).
So instead of sharing it and allocating it as needed, it's locked off totally from the OS in the event it's ever needed by the hardware.

Ok guys i get the gist of it now, thank you all.

12GB RAM ???

For my usage even 6GB ram in my S9+ is enough, so the 8GB version of OP7 Pro should be more than enough. The question is: is 12GB RAM going to be FASTER than the 8GB in any way when only using ONE app\benchmark\game at a time?? Cus I want the FASTEST.
As far as I know about how PCs work, more Ram only helps if you are using it... but then why did OP ''leak'' the cpu benchmark from the 12GB variant? https://www.gizmochina.com/2019/05/...isting-confirms-12-gb-ram-and-snapdragon-855/

You already know the answer.
By the time you need 12 gigs- you will probably become some 3 years older from now -- when a different SoC, GPU and the OS would actually want to make use of it on extremely intensive tasks.

Perhaps - but if you get 2-3 Andiiod upgrades and you pass your phone on to kids, grandma or someone who's less of a power user, having a phone that works can be better than buying them a new one.
Or if things keep going the way they're going, you keep the phone yourself because there's no significant upgrade that merits buying a whole new phone as long as the current one still works fine.

In both cases I doubt how much of a role the 12 gigs would play(highly doubtful) at all in comparison to 8 gigs, as that "additional" 4 gigs will have little to do with the system but a newer redesigned SoC definitely WILL - which will be absent.
I mean just adding some "Access gigs Of RAM " will not make the phone futureproof.

How many nand chips make up the 8Gb and the 12 GB?
If there are more chips in the 12gb version then it will eat more battery.

Just ordered the blue 12 G version ?

Unfortunate that 12GB is only available in blue.

Im about to order the 12GB version just for bragging rights. Does the 12GB actually make a difference to the performance? Unlikely if say. I have a 6T Mclaren and the 10GB makes zero difference over the ordinary 6T but with the Snapdragon maybe the extra ram is utilised who knows. Anyway Im hesitant as I don't want what Happened to the 6 to happen again a special edition Red color soon after. That really makes me angry. I was lucky to get the McLaren when I did. Don't want to spend over €800 and see that happening all over again.
