This is the best radio for me, tha latest has bad signal reception.
Typing free on terminal reveals 423816 RAM
Subtracting 128mb out of 576mb gives a greater number.
From what I have read, only the latest radio gives 576mb, so what can I do?
It all depends whether you (or the system) are displaying 'the number of megabytes available' or actual megabytes.
The discrepancy comes from 1 Meg being 1024 k,, 576 Meg should be seen by the system as 589824 kilobytes, but rather than give you free memory manufacturers sometimes actually give you 576000 kilobytes which converts to 562.5 Meg, but they can say '576 meg' because we all know that a thousand kilosomethings are a megasomething, so 576000 kilophants is obviously 576 megaphants, right? course! not.
Also, the way it is displayed to you makes a difference, because one app may say 'you have 100 megabytes free' whilst the next program says 'Free RAM 102.4MB'
both are correct and the same, 100megabytes = 102400KB = 102.4MB (but not really 102.4MB, thats just maths taking 102400 kilo and turning into mega, , its wrong, but it happens a lot when a display converts a large number into less digits, )
Hard disk manufacturers do something similar, when you buy a 1gig hard disk you actually get 1000 x 1000KB which is 976.5MB, or less often 1000 x 1024 = 1000MB but we THINK we are buying 1024 x 1024 kilobytes to give 1048.5MB, or 1 actual real gigabyte.
Also, your current radio should unlock the ram so long as the rom is compatible.
Your figure of 423816 ram converts to 413MB, and my phone shows '412MB ram', which is as close as i need.
Im sure ive made some glaring maths slip up there (im a little ston,,err distracted, , but the point is you never really know if you are looking at real megabytes or marketing megabytes, or mathematical megabytes, so figures around what you expect are generally ok.
Hello all,
did anyone calculated memory in our Notes?
2Gb - / "system disk"
11Gb - /mnt/sdcard
But we should have 16Gb. So, 3Gb is missing. Where is it ?
When 16 GB is indicated it's never the full 16GB, the same goes for 32GB...64GB....ext, they always round up to the nearest increment. It is deceptive, but that's just how they do it with solid state memory.

Yep. When the last time you saw increments other then 4,8,16,32,64,128...for solid state memory.
when manufactures advertise 16gb, theyre going as in 16,000,000,000Bytes. but most OS will read it in terms of binary, and the nearest number to 1000 is 1024 (i suck at phrasing).
so 16,000,000,000bytes divided by 1024bytes per kb = 15625000kb divided by 1024kb/mb = 15258.8mb divided by 1024mb/gb = 14.9 gigabytes. now subtract the 2gb for the apps partition and thats 12.9gb. now i dont know too much about the little things to do with android/linux, but i would assume that maybe 1gb or so would be reserved for the android OS itself, or some of it is used as virtual memory.
So the 16GB has total space 11.94 and the 32GB has 26.11 when you look in storage on both devices. Shouldnt total
space be 16gb and 32gb. Im not talking about available ...I understand the operating system takes up storage...but total space is missleading as far as im concerned..and for anyone on the fence as to which size to get...forget about the 16gb if you plan on doing any kind of gaming.
I downloaded N.O.V.A 3 which by the way looks awesome and plays awesome on this device...but it takes up 2.8 gigs of physical space, large files. So I thought the 16gb would suffice...but after putting on about 14 games..the 16gb has 4.3 gb available ...no movies, no music, nothing else.
you will eat up the 16gb super fast..i know theres the cloud but im not using that....but can someone tell me why these tablets dont report the correct total space? anyone else annoyed about this...I had to go crazy looking for the 32gb as you know staples is playing games...wasnt available in stores and still isnt...you can order it now.
The operating system and system apps takes up space?

You can get it from any best buy store today, I got mine last Friday.
Its been this way for eons. A 500GB HDD is not actually 500GB. The partition method takes up space as well.

It depends on both the definition of GB that they are going by: http://en.wikipedia.org/wiki/Gigabyte
Since the early 2000s most consumer hard drive capacities are grouped in certain size classes measured in gigabytes. The exact capacity of a given drive is usually some number above or below the class designation. Although most manufacturers of hard disk drives and flash-memory disk devices[4][5] define 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[6] and some components of the Linux kernel[7] measure using the decimal units. The JEDEC memory standards uses the IEEE 100 nomenclatures which defines a gigabyte as 1073741824bytes (or 230 bytes).[8]
The difference between units based on decimal and binary prefixes increases as a semi-logarithmic (linear-log) function—for example, the decimal kilobyte value is nearly 98% of the kibibyte, a megabyte is under 96% of a mebibyte, and a gigabyte is just over 93% of a gibibyte value. This means that a 300 GB (279 GiB) hard disk might be indicated variously as 300 GB, 279 GB or 279 GiB, depending on the operating system. As storage sizes increase and larger units are used, these difference become even more pronounced. Some legal challenges have been waged over this confusion such as a suit against Western Digital.[9][10] Western Digital settled the challenge and added explicit disclaimers to products that the usable capacity may differ from the advertised capacity.[10]
Because of its physical design, computer memory capacity is a multiple of base 2, thus, memory size at the hardware level can always be factored by a power of two. It is thus convenient to use binary units for non-disk memory devices at the hardware level, for example, in boards using DIMM memory. That is, a memory capacity of 1073741824bytes, for example, is conveniently expressed as 1 GiB as opposed to 1.074 GB. Software applications, however, allocate memory in varying degrees of granularity as needed to fulfill data structure requirements and binary multiples are usually not required. Other computer measurements, like storage hardware size, data transfer rates, clock speeds, operations per second, etc., do not depend on an inherent base, and are usually presented in decimal units.

That't not nearly as bad as the Windows 8 tablets where you only get like 5GB of free space on a 32GB model.
The 64gb Microsoft Surface has like 26gb available to the user!
It's normal. Android needs memory. So the "Total Available" is what is left after system files.

I mentioned the tablet is reporting total space. The total space should be how much storage the unit has period...I know that
the units use system files ect and this takes up space, and there is an "Available" bucket...not total available.
If you buy a tablet and its a 32gb i'd like it to say 32GB for total space. granted there are system files...approx 4 gb.
the next bucket says available. This is where it should take into account your files as well as the system files it uses...am
I making any sense? and truthfully im sure it will come out in two months from now as they released a 32gb version of the first version.
Im sure we will see a 64gb version which probably is needed since there is no memory expansion...im just wondering why they can't
include a memory card slot so you can increase your storage...oh wait...they are holding back for version 3 july 2014.

A 500GB HDD is not 500GB because they count 1 gigabyte as 1 billion bytes on the packaging where a computer, which counts in powers of 2, counts a gigabyte as 1.2 billion bytes. So when your device gets formatted it looks like you lose storage. Blame jerks in marketing who like bigger numbers to be on their labels.

Faulty analogy to hard drives. Big difference between GiB and GB...
Device manufactures advertise total chip capacity prior to partitioning. This is misleading to consumers. Not only do we get the GiB loss, but we also get the loss from the system required partitions.

Guys if you do the math 32 GB equals to 30.5 GiB but it says 26 GiB total size. Where goes the 4 GiBs?
Guys I think he means this they advertise it as 32 gigabytes but we oy see 26.11 TOTAL ( which includes system files )

Even though I'm not surprised every by the usable amount. But the first manufacturer two put nand chips in their devices and say put a 40 fb nand for user storage and round down to whatever whole number and market it as that size.
The marketing would sell units
Why with x device you by a 32gb model and have less than 30 gbs to use.
Well with our models when we sell you a 32 fb model you'll get 32 fb
Then pan out to a frustrated surface pro user trying to download a movie
Edit the second nand would be for system only

Your math is broken.
I don't have a 16GB model, and am too lazy to look at my 32GB one, but let's say the OP's account of 16GB=11.94GB free is correct.
The 32GB model would have approximately 16,000,000,000 more bytes. Let me repeat. 16,000,000,000 bytes. As it's been explained, while available storage and file size "GB" is represented as 1024x1024x1024 =1073741824 bytes = 1GB, drive sizes have always been 1000x1000x1000 = 1 Billion Bytes. This isn't new. If you don't understand this basic concept, do some research.
Ok, moving on. So, if the 32GB model has 16 billion more bytes, how much is that in what we consider to be a gigabyte? That would be 16,000,000,000/1024/1024/1024 = 14.901161194 GB.
FYI - This number doubled (aka 29.802322388 GB) is what 32 billion bytes equals.
So, if the OPs numbers are correct, the system OS, preloaded apps, etc. take up only 2.96GB because 14.9 - 11.94 = 2.96.
If we subtract 2.96 from the 32 billion byte figure, we are left with 26.841161045 GB remaining.
I agree that this number is a little odd, since it appears there is a difference between that and the 26.11 number the OP is reporting. Assuming their numbers are correct, this would be a difference of about 730MB. I doubt the two versions are formatted differently, and other variations shouldn't account for such a large difference. However, the difference isn't as extreme as some people seem to be indicating.

Have you ever experienced that moment where you insert
your 16GB memory card into the camera only to discover
that this new, freshly formatted card is a nickel short of
15GB? Or a 32GB card turning to 29.8GB once installed?
Have you ever wondered where those GigaBytes are hiding?
The truth is that they are not hiding at all.
It has to do more with the way card companies (and hard
drive companies too) decide to annotate their products.
In English Kilo means one thousand (1000 1 = 1,000), a
Mega is a million (1,000 2 = 1,000,000) , a Giga is a billion
(1,000 3 = 1,000,000,000) and so on (Tera, Peta, Exa, Zetta &
Toyya). This system is called the SI units system .
In Computerish, however, the numbers are a bit different: A
Kilo means 1,024 1 = 1,024, a Mega is 1,024 2 = 1,048,576, a
Giga is 1024 3 = 1,073,741,824 and so on. This is called the
Binary units system.
So there is a difference in what Kilo, Mega and Giga means
and that difference is getting bigger the "stronger" the prefix
is.
For Kilo, the difference is only 2.3%, for Mega it is 4.6% and
for Giga it is 6.8% - see a pattern here?
Back to the memory cards.
Memory cards manufactures choose to use the SI system to
denote cards sizes. Our computers and card readers use
the binary system for size calculation and here is where the
missing Bytes are.
Of course, the card companies are covered, they do mention
this fact on their sites (in a small asterisk, or with hover text
that is revealed when you hover over a small asterisk). Here
are screen shots from three leading cards and hard drive
manufacturers, though they are not the only one to use that
practice:
Sandisk:
Lexar:
Seagate:
If you followed the math, you probably realized that the toll
this calculation method in taking gets bigger the bigger the
data units are. So while the toll on a 1GB memory card in
way smaller than on a 1 tera hard drive. Have a look at this
table to sum things up:
Size SI
units size
Binary
Size
Delta
(%)
Delta
(GB)
512 Mega 536870912 512000000 4.6 0.02
4 Giga 4294967296 4000000000 6.9 0.27
16 Giga 17179869184 16000000000 6.9 1.10
64 Giga 68719476736 64000000000 6.9 4.40
1 Tera 1,099,511,627,776 1,000,000,000,000 9.1 92.68
4 Tera 4,398,046,511,104 4,000,000,000,000 9.1 370.71
1 Peta 1,125,899,906,842,620 1,000,000,000,000,000 11.2 117253.43
Now What?
Now, I think it would be fair if we politely asked memory
card makes and hard drive makers to switch to binary so
they will be better aligned with the way we use them.
