2gb ram or 1.5gb?

Isn't this phone supposed to come with to two gb ram?
How come it says 1.5gb

Weird. It shows 2gb in about>hardware but in apps it shows 1.5. Rom toolbox also shows 1.5.

Perhaps 512MB dedicated to system RAM only

500 MB is probably being used by the GPU

1.5GB of RAM is available to these running applications. If you navigate to Settings > About> Hardware Information the 2GB value will be seen. 0.5 GB is dedicated to ensure the device software runs smoothly.

All thats says is that its "used by something else". The question is what.
And judging from how its worded it seems like its referring to the 0.5 GB going to the GPU.

It actually says its used to make things run smoother. I don't know how much you know about hardware, but GPUs have their own ram. A phone GPU wouldn't share system ram. Ram is used to hold temporary files such as an open app. As soon as that app is force closed/force stopped then that information is flushed from ram. Think of it like having a dual core processor. One core of ram keeps the currently running app or apps in its memory. Meanwhile, the other 512 mb core holds just system software. That way your apps are never making your Sense/ROM/etc slow. Its pretty smart.

Most devices do this. The reserved RAM is to store critical processes like the dialer, base Android process, and other related things.

The operating system requires ram to actually run, its no different than a pc, total ram is not the same as available ram.

I'm 99.999% sure that the ram you are not seeing is system/hardware reserved memory that would not report as available memory.

Most phone GPU's dont have dedicated memory and would in fact share system memory much like most laptops graphics cards.
Pretty sure if you cat /proc/iomem you'll see the addresses of the ram that has been reserved by the system.

I echo this. Basically it is just all a matter of how the system is reporting the memory. On my Note II, it shows almost all of the 2GB, on my HTC One, it excludes the system reserved memory.

Internal Storage only 8gb

Hello everyone,
My internal storage is only 8gb, and it has to be 12gb (as i saw it on screenshots)
I had an bricked note, and had to use Pit files to revive it | thread | (i got it at a REALLY low price due to this )
I have read that there are pit files to get back 1 or 2gb, i dont know if this is true? i have searched for them but i cant find them
Does anyone know anything about this?

Damaged emmc is where a section of the chip becomes unwritable through corruption. There is no way to recover this damaged space except by replacing the chip, and as it's hot soldered onto the board, they just replace the entire motherboard which is v expensive. I don't know what process you took to recover the emmc, but I imagine it was by scanning all sectors and bypassing the damaged portion in which case 8gb is all you're gonna get, and fairly standard I'm afraid. Sometimes, if you're lucky, repeating the scan of sectors can free up some more space.
Because of the limited space, you might experience freezes and reboots on stock roms because of their size, if this happens, just try a deodexed or cm based rom.
All the best, let us know how you get on.

I didnt use any scanning method via the recovery because it was too buggy to use,
I used an .pit file to repartition, it was for the common emmc bricks.
I do sometimes get random reboots (just reloading android, no real reboot) but it isnt really an issue, just have to do an real restart else battery will drain
After all for 70 euros im happy with the device, it has no major issues else than sometimes the random reboots
I think im a lucky man fixing the emmc brick?
Thanks for ur help! Atleast 8gb of space 32gb microsd card will help

RAM usage

Yes with 4.4.2 we get more RAM, but the phone is not using it. In 4.3 I could easily keep 9-11 (2.2gb RAM/2.38gb) apps running in the background. 4.4.2 it now stays around 5-7app using (2.0gb RAM/2.71gb). Anyone else notice this?

Tell me again how a software update will give you more ram? You don't get more ram. Sorry. What you got was ART which doesn't even matter with the Note 3 because our hardware is TWICE as powerful as most stuff out there. Its sad... Kit kat has never been what it was meant to be. Think of it like Morpheus with the blue pill and the red pill.

As far as I know the Note 3 did not get ART. As many of you may know, when you wipe the dalvik cache and reboot the phone
"optimizes" all installed apps. When I had KitKat ROMs with ART enabled on my Galaxy Nexus it would take forever to "optimize" everything. My Note 3 running KitKat optimizes all 200+ apps in less than 2 minutes, much like my Nexus did when I was using dalvik. Based on these observations I believe that we're still stuck with dalvik.
I am using a custom KitKat ROM on my Note 3, so maybe the official OTA has ART and the ROM I'm using doesn't? I don't see an option for it in the development settings and I doubt the developer would remove it.

Well first of all, the note 3 is 5 times as powerful as the gnex. Secondly, if that's the case and we don't get ART because our hardware is so badass, then tell me what was the point of the upgrade?

According to this article (link below) Samsung removed ART from its 4.4.2 update. The author didn't specify which version of the Note they tested, so it may or may not apply to the AT&T or other US variants of the Note 3.

Upgrade from what? My Nexus or 4.3 on my Note? I upgraded from my Nexus because the battery life was absolutely terrible, the screen was cracked, the reception was awful, it was a 2.5 year old device, and I wanted a giant phablet with a stylus.
I upgraded from 4.3 on my Note because I wanted to try out the mighty Knoxraid that was being praised on this forum. If I was going to flash a custom ROM I figured that I might as well use one based on the latest version on Android, with or without ART.
I'm not trying to start a fight or anything. I'm just stating my opinion based on my experience with ART on my old rundown Galaxy Nexus and what I've read...

Let's not make this an argument over which roms are better than others....
Stay on topic, thanks.

[Q] Only 23GB "Total Space" on 32GB Nexus 6 right out of the box?

Anyone else notice that right out of the box you only have 23GB of usable storage on the 32GB variant?
I know that you'll never get the full storage amount due to the ROM taking up space. However, on both my Nexus 4 and Nexus 5, with 16GB total space, I had at least 12GB available right out of the box. So I'm used to having ~4GB of unusable space. But 9GB of space taken right off the bat for a pure Android device with no bloatware does not seem right to me.
Anyone know why this might be?

Starting from lollipop, the phone uses art run time. Art takes up more space in the internal storage, it's one of the tradeoffs when compared to dalvik.
And no you can't change back to dalvik on lollipop.

Good to know. Thanks!
I guess this is just one more reason many should opt for the 64GB.

Now that I'm on a computer, I can elaborate my point in more detail,
Android 4.4 KitKat, at least on the Nexus 5, includes a new runtime call “Android runtime”, ART. Though it’s not a very creative name, it is pretty creative in what it does. Unlike JIT, which must compile every app whenever it’s loaded, ART works on a concept called ahead-of-time (AOT) compilation. With ART, when you download and install an app it automatically pre-compiles. This takes up more space on your device and takes longer to initially install when compared to Dalvik. However, apps launch quicker and are arguably faster when run using ART rather than Dalvik. What’s more, since less time is required to run apps, your processor doesn’t get worked as hard and your battery life may benefit as a result.

Do note that the above is from Kit Kat's ART which can be different from Lollipop's ART (improved and more finalized)

This isn't much difference to the 32gb Nexus 5 which has 26gb.

That's weird -did you get a carrier model vs an unlocked one from the playstore?
People were posting 25GB free last week for the 32GB....

I have 54 GB free "total space" on mine.

I got the the 32GB

You have a 64gb. System overhead seems to be about the same as OP's.

OP, were any carrier apps loaded on during setup? If so, remove and get that space back.

For this phone, only AT&T gets carrier apps pre-loaded. To be honest, a lot of the Google Applications are bloatware.
Bloatware examples are: Fit, Earth, Books, Movies, Google+, etc.

I agree with you, but to the OP's issue, he may regain some of his space by removing them, it's been said that you can remove those said carrier apps. As to the others, they may be removable, or one may need root if they are loaded just in /system. Thing is the OP hasn't stated if he got a GP or moto phone, or one from a carrier to begin with.

Initially I was disappointed with the seemingly low space, but you have to keep in mind that a good chunk of that 32GB is lost to formatting (I'd estimate around 10%-15%). The rest is used by the operating system. So 24GB of free space is very plausible on a 32GB device.

Correct I was posting that as a comparison seeing that mine has about the same amount of space taken up.

Is the 8gb Ram on Note 9 fully usable by apps.

I have a note 9 512gb variant with 8gb ram. However when I go to apps in settings none of the apps report full 8gb ram. See the attached screenshot. Storage is reported correctly by apps but not ram.

That's because all the running and cached apps take up an enormous chunk of the ram, I have the 6gb version and barely have 2gb available ram, shocking really, I am pretty disappointed, you should be even more so haha.
I even have over 100 apps disabled which did free up a bit, but not much.
I have a le eco le max 2 with 6gb ram with a custom pie rom on it, with almost 5gb free at all times.
I see no performance issues on the note 9 but it seems daft to advertise a phone with 6 gb of ram where barely 2 is ever available. Obviously any operating system and running/cached apps are going to take up some of that ram...but really over %60?

2GB of RAM are eaten up by "SWAP" on this phone.
I'm no expert on the subject or a developer, so, here's a thread that touches on the subject:

Verify it for yourself with the app RAM TRUTH:

Unless you're rooted, (AFAIK) there's nothing you can do to change how RAM is used.

But does it really matter day to day? I honestly don't notice any lag with my N9 (6GB). I wonder what kind of paces some of y'all are putting your N9 through that makes negative RAM performance actually noticeable. But I guess I'm not really that kind of user?

Same here, but, I'm glad I opted for the 8/512 version.
After experiencing 8G RAM on a few phones (BlackShark/OnePlus 5T/RazerPhone), I wasn't about to pass up the option, especially on a Samsung device, running a much heavier skin than vs the abovementioned. Out of all of those (Note9 included), I'd have to say the RazerPhone seemed smoother/faster, but not by very much.

remember the Android Mantra; "unused ram is wasted ram"..
forget about how much free ram is "available"; it means absolutely nothing on a modern Android Phone..

The RAM usage is different. Android works accordingly to what is available.
4GB, 6GB, 8GB.
It actually utilizes what is available. The more RAM you have the more it will use

Well... Running Bitdefender in the background and my phone is not even reaching 4GB.
Anyway more is better than less, I'm sure some future version of Android will take full advantage of that RAM
