Hi,
I think this might end up being a bit of a dumb question, but here goes..
In my XDA IIs, there seems to be a blank SD card in the top of the unit, as in it is just a piece of plastic. However, if I go in to Start | Settings | System | Memory, there are two tabs, the first is the 'Main' tab which is 125.77 MBs split evenly between 'Storage' and 'Program'.
But then on the 'Storage Card' tab there is a further 43.26MB. Where is this coming from if the SD is just a pice of plastic?? Also if I take out the pice of plastic, and go into file manager and look in 'Storage', all the files are there and accesable.
So, in summary, where is the SD memory coming from if it is just a piece of plastic in the device? And if it is just a piece of plastic can I just replace it with a 2GB SD card?
Yours,
Confused in Leeds.
Storage folder not reffers to the sdcard , but on chip that is in the board of your XDAIIs ....
you can replace the peace of platisc with a sdcard ..
you'll have already the 'storage' folder wich is 43,26 Mb AND a 'Storage Card' folder wich is your sdcard capacity .
the piece of plastic is exactly that, just a piece of plastic.
when you put in a real sd card, you'll have 3 memory sections: main memory (the ram - volatile memory), storage (non volatile flash memory left over from the rom), and storage card (your SD card)

XDAII default setup
there a folder call storage card
and it's taking 14mb of space
how do i deleted that, and free 14mb?
i have sd 1gb card, which is in another name. so i don't need to storage card folder.
the storage card folder is always there, ever since i got this xdaII without a sd card.
The folder called 'Storage card' is actually your non- volatile RAM - originally intended to store a backup your contacts and such in case of a hard reset.
Which is what the 'flahman' programs are in your startup folder - they run the backup system for your contacts and calender and such.
It is actually RAM space on board the processor chip (Or so I Believe) so you are not losing any RAM from elsewhere.
It cannot be moved, but if it really bothers you, you can remove an entry in the Registry to make it disappear.
Hello,
Can someone elaborate on what is meant by Storage memory and Program memory?
I would expect storage to be My Docs and Programs to be Windows and so on. I ask since my Storage allocation is two thirds full and all my docs on the device is empty. I use the SD card for that.
Cheers.

-Storage memory is memory used for saving files on you're phone, extention is you're memory card (micro SD).
-Program memory, is like the RAM-memory on you're PC, this is used when running programmes, watching movies-pictures...
Thanks. Well there are two storage areas. "Main" and "Storage Card". My query is for "Main". Within this there is "Storage" and "Program".
I would like to know what is used for what so I can look in a specific area and delete stuff I don't need. Like I said "Storage" seems rather full but I do not store anything on the phone itself. I use the storage card which does not present a problem.
In the storage info on the settings tab, under device it shows "storage" which is like your hard drive, and "program" which is like your RAM. Obviously, you don't actually have a hard drive. It's just an example
There's certain stuff that gets cached on the internal storage, and this can obviously bump up the space that's used (there's threads on here for cleaning/moving these things). Then there's the other culprit - Marketplace. If you've installed stuff from there, it's on internet memory, not your storage card. Also, do you install software to the device, or to the storage card? I only put essential stuff on the device, and stuff that I can live without on the storage card.
Just thoughts and suggestions.

Ah ok that explains a little then. I have been installing cabs to the device.
Do not understand; my total storage memory is 181,23MB, in use is 175,21MB, but when I check in explorer, there is only 89MB in use. What am I missing here??
Also, what does it mean program storage - total space 336,97MB?
Flash size 512MB, RAM size 448MB, what is the difference?
Its rather more complex than it ought to be, and HTC are being a little 'economical' with the truth!
It has 512MB of total storage, of which about 175MB is taken up by the ROM image. This leaves the 337MB you see reported. Of this, about 150MB is taken up by the HTC Sense system, then another chunk by the video memory leaving around 135MB free to the user. The new 'Light' custom ROMs without HTC Sense have over 300MB free to the user.
The 448MB RAM is just that- same as a PCs RAM. Even after loading the OS on startup there is ample ROM left for pretty much any eventuality!
So, I was wondering if it would be better to install apps on the memory card or on main memory. In terms of stability, performance, etc
Thanks!
Main memory.

Yep, main memory especially if you're using the crap class 2 card that came with the phone.
I usually install games/apps that i use frequently on the phones main memory. All other games/app, I install it to the storage card. It is stable for me and also leaves space on the phone for other things.
I agree with halojinx. I try to keep my device memory as empty as possible. I throw the large files on the storage card and create shortcuts to them with quicklinks. That way my phone runs quicker. Works for me. : /
Since we have such a big system memory, I have no idea what would drive you guys to move your apps to your SD card.
I know I keep all my .cab files on my SD card, but all my installations go to the system memory.
I have 8gb class 6 micro SD, but the 16gb holds so much more music and video files, I don't really use the 8gb anymore.
rickyoon.vegas;
I agree with you. We have more than enough memory to install a huge amount of apps in the main memory.
Installing it to the main memory won't take up your RAM space for apps to run.
Main memory will use less of your battery also and will not cause your HD2 to freeze because of the generic card that came with the unit.
Yes, there's a metric crapload of on-board memory for apps on the HD2...I think it's a much better policy to install all apps to the phone's memory, and just store the cabs themselves on the storage card. I also believe that installing apps (and all their related minute little files) to the SD card can cause device lag in general when the phone is trying to index the card.

Sweet. I was thinking "oh, when I flash I won't need to reinstall the apps if they're on the SD card!" Well I was still installing them after I flash, so I figured I may as well just start installing them to main memory.
Yeah, the crap Class 2 SD card makes me nervous. Once I have the $50, I'll go buy me a nice Class 6
Thanks!
I read the FAQ thread and it says that of the galaxy s2's 16Gb internal storage, only 2Gb is user-available. Is that really true? I figured there was probably some other thread discussing this in more detail but I couldn't find it. Any pointers?
I can understand android + touchwiz taking up a little, but that difference is too huge. Does anybody know how the 16Gb is used, and how much is available for different purposes? Eg I could imagine maybe they have user-installed apps and user-data as two different partitions within the (16Gb - android - touchwiz).
For comparison my understanding of the sensation and evo 3d is that both of those have a 4Gb chip for internal storage and both have 1Gb user-available.
on my sgs2, there's about 2GBish of "device memory" (that's the default place for your apps, etc), 12GBish of "usb storage" (the rest of the internal memory) and 15GBish from my removable microSD card.
That 2GB is for installed applications storage, you get roughly 12GB of free flash memory storage to store whatever you want and the rest of it the phone uses for non-accessible things - system and OS-related, etc.
By the way, it's GB (GigaBYTE) not Gb (GigaBIT), or GiB (GibiBYTE) if you want to get more pedantic. A 'bit' is roughly 8x smaller than a 'byte'.
As I know, HTC sensation got 1gb internal storage for installing apps, and it had not extra space for storage.
thanks
Thanks everybody, having 2+12 Gbyte makes a lot more sense than just 2Gbyte. Glad to hear it does indeed have the space it's "supposed" to.

it comes with an 8GB microsd card
So the SGS II has:
- internal memory : 2GB
- internal SD: 12GB
- external SD: up to 32GB
My question is, can you install an application on all of those mentioned above?
Or only on internal memory and external sd? Because on the app's properties page u have the option to move it only to internal memory or external SD.
Why?
Sorry if this question was asked before, I'm new to Android, and I did make a search before I asked, but I couldn't find this information.
I installed App2SD, but the movable apps only moved to the INTERNAL SD, not the external_sd.
All the things that installed and or created by the user or the apps themselves would go to the INTERNAL SD, and the external_sd is only used by the user manually putting things into it.
Since SGS II is one of the first Androids with 16GB "internal" Mem PLUS option to insert msd-card app2sd-apps are not modified to move to the "external_sd" which is actually a 2nd sd.
What I dunno if Android itself would allow to read apps from a second sd.
With time there will be an app that can manage this but not yet ............

I have 2 questions I am fairly new to the a500 although I have had an evo 4g for years and I have been flashing roms for many more.
I know thebquestion has been asked is there a way to move apps to the sd card. I am wondering if darktremors app2sdgui might work for our tablets and if so how to ise it. I have been seeing threads where people are using 64gb sdxc cards but whats the point if you cant move apps. Im starting to think thosbtablet sucks half the games dont work and you cant freely moves apps.
Anyway my other question is if there is no way to use app2sdgui is there any roms available that allow you to move apps and still have all the tablets good features? I have searched and from what I can tell most roms dont really say they can do it.
Thanks from the bomb

Wrong forum. This should be in the questions section.

I don't have a full understanding of all this myself, but I *believe/think* that the A500 is already moving apps to the SD card -- the internal SD card. The 8, 16, or 32gb of memory that came with whatever model of A500 you purchased is considered the internal SD card, whereas the micro sd card slot is considered the external SD card. Your tablet has 1gb of RAM, which in phone terms is thought of as internal or system memory, like your (and my) EVO 4G has 512mb of RAM. Since the EVO doesn't have any internal SD card, in order to run the newer, larger footprint ROMs we have to use an apps2sd type utility to move as much as we can to the external micro SD card in the EVO 4G.
If you're running out of internal memory in your A500, you can move some data that seems to default there. This happens a lot with apps that aren't really designed for tablets because these apps think that your internal storage is your external micro SD card. I moved all my photos, music, and eBooks from internal storage (where they defaulted) to my external micro SD card. Now I'm only using around 4gb out of the total 16gb that came with my model of A500, and I have tons of apps, games, etc installed. Moving the data barely put a dent in my 32gb external micro SD card, which I mostly use for 720p movies/videos.
Anyone please feel free to correct me about Honeycomb tablet memory handling above!
It's a limitation of Honeycomb not the tablet. Hopefully ICS when it's released soon will solve this problem. I don't know why google designed the tablet specific OS Honeycomb like this it was stupid. There are several work around programs like GL to SD that work so so. I had GL to SD installed and it severely slowed down my tablet so I got rid of it. My first A500 I bought was the 8gb version which I returned a week later after buying the 32gb unit. The 8gb just didn't cut it without being able to take advantage of the sd card for game data.

No its not like this. The phones do have internal memory also. The ram has nothing to do with internal memory, even tho some advertise the ram and internal memory as greaterstorage

Thread belongs in q&a section not dev sorry all
Ok sorry but my testing with the gl to sd app...
the order of chaos game i used that app to move it.. The game took forever to load and ping times went so High you could not play the game..
I Have a pny class 10 16 gb sd card.. tested to get about 8.7 mb transfur rate. and that is about average on most so called 10 mb (class10 cards)
my tablet runs very smooth with no apps running in background.
so i DO NOT RECOMEND THESE APPS.. Just my openion dont bash me if yours is diffrent.. i also dont understand how people are filling up the 16 gb tablet.. that alone has to be slowing your tab down...

You're confusing RAM and FLASH storage. Many older Android devices have a very small area reserved for applications and ROMs, it has nothing to do with RAM. RAM is memory where applications are loaded when you wish to execute them and gets erased every time you power off the device, flash storage is where the applications are stored and loaded from.

I've got the 32GB version + 16GB microSDHC and it's already filled to the brim. I just happen to consume lots of media, including comics, movies, music and books.
Also, the tablet doesn't specifically slow down by the amount of files on it, the process of indexing everything can temporarily slow it down but after indexing is done it doesn't consume resources anymore. Using some sort of an application that just loads everything to memory and doesn't care about trying to watch how it uses the memory is has reserved however can and will slow the tablet down, but that's an application issue, not a filesystem or OS issue per se.
So if the internal memory is like is primary I can't see why it wouldnt be easy to make the external micro sd and ext of the internal. Is that possable?

I found this post online for switching internal to external in honeycomb. I'm getting a 64gb sdxc for my 16gb a500 so it should come in handy.
I have had a mod to voold.fstab under previous Android versions so the OS looked at the physical MicroSD as the external card, not the internal 8 gigs in the Adam. Handy because some programs always wants to look for files on the external card. It was quite easy to do the same thing to Honeycomb, and in case anybody else needs it, here's the full code for the file (which is under \ETC, you need Root Explorer or simalar to edit/replace it):
Code:
## Vold 2.0 NVIDIA Harmony fstab
####################### ## Regular device mount ## ## Format: dev_mount <label> <mount_point> <part> <sysfs_path1...> ## label - Label for the volume ## mount_point - Where the volume will be mounted ## part - Partition # (1 based), or 'auto' for first usable par tition. ## <sysfs_path> - List of sysfs paths to source devices ######################
dev_mount microsd /mnt/sdcard auto /devices/platform/tegra-sdhci.2/mmc_ host/mmc1 # todo: the secondary sdcard seems to confuse vold badly dev_mount sdreader /mnt/external_sd auto /devices/platform/tegra-sdhci. 3/mmc_host/mmc2 dev_mount usbdisk1 /mnt/usb_storage auto /devices/platform/tegra-ehci
So the actual changes are in the fourth and third lines from the bottom, changing around a few numbers. You'll see the difference if you open the original. I have saved a copy of it on the SD card, so if (or rather when) the next update comes I can simply copy it to the \ETC directory with Root Explorer and do a reboot, and it's back where I want it.

Yep, makes sense now that you both mentioned it. Sorry about that. So, it would seem to me that HC actually isn't using any A2SD solution, it's just that tablets typically have significantly greater internal storage and Google didn't expect anyone to really need it. If that's the case then it at least makes a little sense to me that HC doesn't have that built-in and than not many devs seem to be working on this type of project, especially for an A500 which can so easily use external USB storage for the usual storage hogs like media files.
i cannot see why people are so hellbent on apps2sd. seriously, i cannot. well, okay. i admit that it /does/ free up space on your internal apps partition.... but i can't see the point of wasting space on your external SD card.
the apps partition on the iconia tab is roughly 1GB. that's not too bad, unless you've got HD games and crap. i remember Sonic CD and Gameloft's NOVA 2 download stuff to the internal storage; which doesn't clutter up your app partition (the game is like 5mb for sonic cd and like 20mb for nova 2 on the apps partition, the rest is loaded from internal SD).
also, the tablet doesn't suck, if you're having issues with games, they aren't optimised for the advanced hardware that is used in the Iconia Tab. this is tablet hardware, not a smartphone logic board with a few addons and a sexy HD screen. the app developer hasn't taken the time to develop for tablets, most likely.
i guess less is more for me, but w/e.
How does apps2sd actually work? I haven't paid any attention to what filesystem format the internal SD is, but wouldn't just symlinking files work? Or does the Android kernel support loopback filesystems? I'm just wondering, perhaps I'll dig some details myself just for the sake of curiosity and see if I can come up with a solution.
Apps2SD works by moving programs residing in /data/app to the SD card. This can be accomplished in two ways:
1. Classic Apps2SD - This form is mainly used for Android units prior to Froyo, but can be used on Froyo and Gingerbread (and I presume Honeycomb and ICS, but I have never tested it with those Android platforms). By using a Linux partition that is formatted on your external SD card, the /data/app directory is symlinked to that partition. This tricks Android into thinking it is still storing applications in your Internal memory when, in reality, the programs are being stored on your SD card. The upside to this format is that any program can be moved over (and it is done automatically). The down side is that you will need to create two partitions on your SD card (one Linux partition for Apps2SD and one FAT32 partition for SD card storage) and your kernel must be able to run scripts on boot.
2. Secure Apps2SD - Starting with Froyo, Google implemented their version of Apps2SD. Their version moves your programs to a secured area of your SD Card and creates binding mounts to the actual programs themselves so that Android can run them off the FAT32 SD Card. The advantage of this is that no special formatting or programming is needed to implement this, as it is part of Android. The downside to this is that, without special programs, not ever application can be moved to the SD card (the program must be recompiled using at least the Froyo SDK...however, this issue is becoming less noticeable as more programs are being compiled using either the Froyo SDK or Gingerbread SDK).
The Acer Iconia A500 uses neither of these methods. The tablet is equipped with 8, 16 or 32GB of internal storage. Your applications are still stored on the /data partition, but your SD Card is nothing more than a FUSE mount to /data/media, which means both data and apps have access to the full 8, 16 or 32GB of internal storage, so there's no compelling reason that I can think of that you would need Apps2SD on this tablet. If you want your tablet to treat the external SD card as the actual SD card rather than internal storage, you would be better off changing the symlink to /sdcard from /mnt/sdcard to /mnt/external_sd (note that, when you do that, you won't be able to move files from your computer to the tablet by simply mounting the SD card, as the FUSE mount is not pointed to the external SD card, but to internal memory...you will either need a creative solution to change the FUSE mount to /mnt/external_sd on boot or you'll need to use ADB).
