Samsung's Lag Fix - Captivate General
http://forum.xda-developers.com/showthread.php?t=762109
Can we replicate this on the Captivate? I've been playing around with my new Epic for a few days and it is AMAZINGLY fast. This is supposed to be the lag fix that Sammy employed on the Epic.
I knew it was just a matter of time until Samsung took action against the lag problem. I mean they wouldn't want their big, bad, and fast galaxy s line slowed to a screeching halt because of lag issues. I wouldn't be surprised if we see this in an update in the near future. With Samsungs track recored though they might end up waiting for Froyo to emplement it.

We have a nand lag fix already right? Wouldn't this give the same results? I thought the ext 2 internal storage lag fix was faster the the nand fix.
http://forum.xda-developers.com/showthread.php?t=737829&highlight=nand+lag+fix
I'm no dev but I think this is the same thing that's already been implemented by the community (for that matter, Samsung probably got the fix from the community )
From what most have gathered, samsung didn't fix the lag, they used different hardware that is faster. That will do no good for captivate and vibrant users.

What the heck?
A) It uses the same hardware that matters anyway (granted LED, keyboard, etc is different).
B) Someone pulled the init.rc and proved what the OP is saying
C) You don't know what you're talking about
is there a good reference for the mapping of /dev/? or the whole file system in general? I went to see if busybox had a symlink for bash and much to my surprise there was no /bin. I'm new to android but a long time linux user and the differences are becoming readily apparent.

I wouldn't go as far to say that. Everything is the same internally other than how the file system is setup, and in this case they are using the NAND (I believe).
From Boygeniusreport:
"We’re assuming the phone uses NAND Flash as the internal memory medium. On the Captivate if you navigate to Settings >SD Card and phones storage you see “External SD Card” and “Internal SD Card” listed. On the EPIC you see “External SD Card” and “Internal Phone storage.” We’ve reached out to Sprint for clarification and will update this article if they respond with a definitive answer."

same hardware, different software...just minor things different
The Epic is missing the 16gb internal SD card... the SD card that Samsung has split into 2GB for apps and 14GB for /sdcard for the rest of the US Galaxy S devices (no idea how the EU phones are set up). As a result, it has far less space for apps, but it more than makes up for it in speed.
About the only thing that I think Samsung can do to improve speed on the rest of the Galaxy S phones is to either work like hell to come up with a better driver for the internal SD card, or to accept a massive limitation in app space and build in the original lag fix.
I'm hoping it's just a driver issue... when copying a 1GB file to and from my /sdcard using the USB mass storage mode, I sometimes see 10+ megs per second, and sometimes see >1 meg per second. This is with my phone sitting idle, nothing else going on at all (except for OS Monitor, so I can see what's going on). That leads me to believe that it's either a driver problem or the internal SD card is the world's crappiest. Seeing as everything else on the phone is very nice hardware, and seeing how the GPS and compass drivers have issues as well, I'm kinda (and maybe foolishly) thinking that it's probably a driver issue. We'll see.
It almost certainly is a driver issue. Formatting the internal SD with another filesystem provides a large boost in I/O performance. It's not as large as with the loopback hacks, which probably result in both subsystems buffering data, but it's enough to make using the device much more pleasant.

not sure if this has been covered already, but it looks like the Galaxy S phones use NAND for internal storage and not a flash card. the following link:

on the Captivate, if you scroll down farther, past Internal and Externa SD Card, you will also see "Internal Phone Storage".

The Captivate has both, as you can see quite clearly in the shell by using the mount command. Most if the partitions are segments of the NAND, using /dev/block/stlXX devices, but /data is /dev/block/mmcblk0p2, the second partition of the internal SD card. All are Samsung's proprietary RFS filesystem, which appears to perform poorly on the SD.

pardon my ignorance, as i truly am ignorant in the subject, but how are logical names proof of physical hardware? could Samsung not have partitioned a NAND chip with different mount points and call them whatever they want? from the tear down pics, it seems that there would be no room for an internal SD card on the PCB. also, from reading around, it seems that all Galaxy S phones are pretty much the same hardware-wise, is this not true for the Captivate version?
again, i don't mean to come off antagonistic. i'm just searching for knowledge.
I just wish everyone would quit calling the system memory an "Internal SD card". There is no such thing. Samsung gave it this stupid name so the simpleton's of the world would realize it was data storage.
SD - Secure Digital is a form factor design. The phone has different kinds of flash memory and no one has yet to determine if the 14GB "internal SD" is a seperate chip from the total 16GB of internal storage.
Comparing this "Internal SD" to a real SD card is just dumb. An SD card is removable, of a certain physical size, has a write protection, and supports built in DRM - part of what Secure Digital means.
I am speculating too, but until someone can pinpoint the chips used on the captivate, we don't really know what this internal SD is made of.

I agree - SD is just NAND with DRM and some other features. I think Samsung just calls it this to separate internal OS/Application storage from user addressable storage. I would be there is one 16GB NAND chip as I have never heard of a 14GB chip. I bet they just partitioned the 16GB chip in different ways, but for some reason gave the 14GB chunk a slower FS partition by mistake.

Ah, good to know then. Thanks!
It is not only a logical name. While there may not be a removable card in a slot, the name suggests, and information in sysfs agrees, that the "internal SD" is accessed via an sd/mmc host controller. This means that many details about the flash are being hidden from the OS - it doesn't know what the erase block size of the flash is, it only sees a device with a certain number of blocks and a partition table at the beginning. Block remapping and wear levelling are hidden, which is why we can't use any of the linux filesystems for MTD devices. And for some reason, I'm not sure why, RFS performs much worse on an mmc device, or at least on this one, than it does on the OneNAND partitions. That it should matter seems a bit odd, as they are both block devices, but perhaps the OneNAND driver exposes some other information or interfaces via ioctl calls that are not present on the mmc device.
It is certainly possible for a filesystem to perform better on the internal SD than RFS does - this is easily demonstrated by formatting it with ext4 or nilfs2, and is also suggested by the improvement in lag that some seem to see with the leaked firmwares. In the future we may not care about alternate filesystems, because we get an rfs module that performs better on the internal sd.

sounds reasonable, thanks. but getting down to it, is it not at all possible that the internal "memory" is a physical NAND chip, albeit partitioned and interpreted logically however Samsung saw fit?
this may seem like a pointless debate, but perhaps if the community knew it was NAND for a fact, they could rewrite this or that to make things faster/better/etc..
here's a link that revers to the internal memory as NAND. not the source i'm looking for, but it's something:

[Q] samsung vibrant galaxy s 4g, Internal phone storage missing ???
I just purchased the vibrant 4g, amazing phone, very fast, much faster than the mytouch 4g, I rooted it of course via"superoneclick. My main issue is what in the world is the issue with this phone showing practically no app storage space, only 256mb? And after 10 apps your down to 191mb ... Also my phone in perticular shows no internal storage space ,unlike the original 3g vibrant shows sd space, internal space, and app space?? I called Samsung tech direct, and they are idiots as well as tmobile! they say that it has only 256 mb app space, and hd no insight on why it shows no internal storage space, how does this justify the advertised 1gb ram /512mb Im sure this is a let down to others as well, or do we have defective phones coming through? I have heard reports of others with 800mb app storage and some as low as 190mb right out of the box.

Im sure their will be further discussion on the issue, as I have already noticed in a few other forums.
most users have ~500 megs available memory for apps stock. the phone only has 1gig internal memory vs the 3g vibrants 8 or 16 gigs. Because we have such a cluster F****ed stock rom right now I would imagine that is the reason why the average available is only 500 megs. Phones only been out like a week or two, give it time memory issues will be worked out. As far as where this post goes, def in wrong section; needs a boot to the general disc forum as it post nothing about the development of the phone.

I talked to Samsung and apparently the "missing memory" is not an issue. I hope I made my self clear as possible since I think having less than 200mb available for apps should not be correct. Samsung told me that they are relying on us to download apps and then switching them to the SD card. Most popular apps at this moment cannot be moved from phone to SD card.

So were getting nowhere with this topic, all I have been suggesting is that are we dealing with some faulty t959v phones or is this 256mb app space "Right out of the box" normal?also what it is supposes to be? Along with no visible internal storage space. I just wanted to.know... so if my phone is faulty i can get it replaced with the 12 days left I have.

If you haven't found it yet this should give you a better idea about the 4G phone. I did my own research. If my understanding of the Galaxy S 4G is correct, you get a 1 GB internal memory (ROM) that's complemented by an included 16 GB microSD memory card, and you can upgrade to optional 32 GB microSD card. Both the 3G and 4G have an additional 512MB of system RAM. Once ClockworkMod is working properly and giving access to modify the internal ROM, the 1GB internal memory will be more than enough to allow the Galaxy S 4G to operate just as well as the current Vibrant 3G with upgraded ROMs. The only downside is the loss of the larger 16GB internal SD memory storage the Vibrant 3G has to 1GB on the 4G.
Using links2sd I have moved 100% of all user apps, 106 currently, to the SD. Even so, I have 104 mb available - phone is working great, no problems to report.
Even though an app can be moved to the sd card, some should not. I use Poweramp and smooth calender, both, have widgets I use, If moved to the sd card the widgets can't load, so they need to exist on the internal memory. After all apps I I have 113 megs left.

They were very tight lipped about why you cannot see the internal memory the way you can with the former 3G model. Just a thought, but can you say encryption? What they were saying doesn't jive with what I've read other places. If you want to look you can compare how they list the specs here in their FAQs. 3g http://ars.samsung.com/customer/usa...ID=2&PROD_SUB_ID=557&PROD_ID=560&AT_ID=301560 4G http://ars.samsung.com/customer/usa...ID=2&PROD_SUB_ID=557&PROD_ID=560&AT_ID=369849
I have continued to move apps that were on the SD from Apps2SD back to phone and then utilizing links2sd to move them back. My memory is now 154 mb available. I have removed move2sd and apps2sd so that anything I download in the future goes to internal memory and then I move it with links2sd. Amazing application!

same issue with vibrant 3g - app space vanishing I've had the same issue with a rooted vibrant 3g. I've removed dozens of programs - bloatware and apps - using Titanium.

To start with the basic troubleshooting - try wiping your caches and fixing permissions. Reboot into CWM Recovery - Go to [wipe cache partition] and select, then select [Yes -- Wipe Cache]. When it is finished - navigate down to [advanced], select [Wipe Dalvik Cache], then select [Yes -- Wipe Dalvik Cache]. When finished - navigate down to [Fix Permissions] and select. When finished - navigate to [*****Go Back*****] and select [reboot system now]. After reboot - do not touch your phone for 10 minutes to give your caches time to properly rebuild. Go in and check to see if your problem still persist. If it does - my recommendation is a Factory Reset. You can do a Factory Reset by going to [Settings], select [Privacy], then select [Factory data reset]. As it says when you do this on the [Factory data reset] selection - by doing this you will be erasing all data on your phone. If these methods do not work let me know and I can help you try fixing the problem with some flashing methods. ---------- Post added at 07:28 AM ---------- Previous post was at 07:06 AM ---------- minimalist83 said: i got same problem, when i go to "storage settings" look like; total space : Unavailable available space: Unavailable mount sd card : Insert sd card format sd card; faded system storage available space 414 mb pls someone help me , i am going driving crazy...

I do believe it has 8gb but 3.2 gb of it is partitioned... Sent from my ADR6400L using XDA App
I believe HTC partitioned it in a way that only 4GB of the 8GB eMMC is usable (the other 4GB is out of reach, it seems), and within that 4GB, you only get about 2.5GB or so user space, with the others reserved for the system. And since it's one time only, we cannot reverse the effects of that partition.
Ya it is pretty ubsurd that you lose about 70% of your internal memory. I do think it was smart to partition space for the system in excess of what is required, just to keep it stable. Also, I imagine HTC had to put aside a hefty chunk of memory for HTC SENCE. However, that seemed like way too much when I first encountered the problem myself. So I e-mailed HTC who told me that the thunderbolt only has a 4GB eMMC under it's hood. That would make the numbers make sense because then the formatted space would be about 3.8 Gbs and that would mean only 1 gb was taken for the system. why doesn't HTC or Verizon address the misprint claiming it has 8GB eMMC ? that is a quesiton I can't answer.

This same question came up when the G2 came out and everyone was rasing holy hell about it. Physically there is 8gb in the phone. However, if I remember correctly (you may need to Google it), the explaination was that because of the way Android uses memory, it is unable to use the extra memory properly. The only analogy that makes sense to me was like how in Windows, unless you set up your hard drive as NTFS, instead of FAT, you were unable to format a partition over 10mb. Samsung got around it by showing the "extra" memory as another "partition" of sorts so the memory shows available. So to make a long story short, the memory is there, but system limitations, along with some of the memory being used as backup cause you to only see the 4gbs. At least that is the way I understand it. Maybe someone else may know more about it and can explain it better.
It has an 8G flash: Code: # fdisk -l /dev/block/mmcblk0 fdisk -l /dev/block/mmcblk0 Warning: deleting partitions after 60 Disk /dev/block/mmcblk0: 4487 MB, 4487905280 bytes There's over 4G available as a flash device to the OS. I suspect the rest is where the radio code is stored, and is not visible to the Linux side.
Assistance needed pertaing to device on-board storage
Greetings all, I journey from the hTC HD2 forums. I have received the hTC Sensation 4G as a gift for my birthday and thus far am liking the device as a whole. My question is in regards to the on-board storage. On the HD2 and a friend's Evo4G, I was able to repartition the on-board NAND to my liking. Since I am more of a CM7(soon to be 9) man myself, I would like to know if there is any progress in this realm. I also remember reading that our device comes with 4GB of on-board storage, yet am only able to see approximately 2GBs of usable space (See Ref.1). I am fully aware that every device comes with partitions for the splash screen, radio, recovery, et.al. but I cannot fathom how this would take up the remaining 2GBs of supposed storage. Can someone enlighten me of this notion or link me to a corresponding thread? The only viable information I was able to find was here. I really like this phone but despise the miniscule amount of on-baord storage HTC built into this supposed "flagship phone" (let alone, the mere 8GB storage card that was included) Ref. 1. (via Titanium) System ROM: 825MB Internal: 1.23GB
I've not seen anything regarding repartitioning the NAND. I'm running CM7 and it's fine with the standard partitions. I guess when ICS comes if it needs repartitioning it'll get worked out at the time. From memory the AlphaRev CM7 partition just increased the Data partition at the expense of Cache and System.
MTD Partitioning might work,Ask firerat is the best thing to do
[Q] How do I make my USB Storage and Internal Storage partitions one in the same?
After reading up a bit on how newer Android phones went about fixing the silliness that comes from having external storage, I realized the Nexus S would be a perfect candidate to convert to the newer MTP method of accessing the device's storage while it's on. I'm already doing this with CM10, but I'm not actually getting much benefit out of it because the device still has an "SD Card". How would I go about merging the data and sd-ext partitions? Since it's all technically one internal flash chip, I don't see there being any major issues with this. Could be very wrong though. I'm using a Nexus S 4G with CM10 Stable, but I don't think that should terribly matter as long as I'm on a 4.X.X ROM with MTP support. EDIT: Is this the wrong place for this question? Like, is there somewhere more technical I should post this?

Making Partitions on SD Card
There have been several posts recently on various threads suggesting making partitions on the SD card. Question: What is the purpose of this and what are the benefits? At present, I'm running CM11 with few, if any, problems. Am currently only using about 1 GB of space on my SD card. I have 55 apps installed. Thanks.
Well, apps and games are different. Games (and I play just a small few of the very many available) take up much more space. The other Galaxy S devices have only 512Mb flash, while ours has 1G. The problem is the other Galaxy S devices also have an internal SD card, where as SGS4G only has external SD card. Considering the fact that SDXC (SD cards capable of >=64GB) is supported (and I tested it the other day), we can move partitions like the data partition to the SD card. The current used space on your SD card is expected to be low. Check the internal storage used on your phone. Sent from my Nexus 5 using Tapatalk

If I make a partition, what should I push to it and should I expect increases in speed and/or performance? Thanks.

I think @FBis251 made a test image and reported that it might not have been as fast as he thought it would have been. Many people have reported success with Link2SD app, and here is a link to one by @Rebel_X.

Probably not going to create one since I'm satisfied with my phone's performance. If it ain't broke....
