Samsung Focus - usable SD card specs?

What is the specs, type and speed, of the SD card that can be used to expand the storage on Samsung Focus? Can someone from Samsung or AT&T answer this?

 

I am not asking about the SD card size or whether I can use it i my PC after using it in WP7.

 

I am asking about minimum hardware specs of the SD cards that can be used in Focus.

Re: Samsung Focus - usable SD card specs?

The reason I thought it needed to be clarified and stated, foxbat121, is that  while many of us here know the difference and so use the terms interchangably, when going on line (or for that matter in stores) people will see all three (SD, microSD, microSDHC) cards for sale and many will not be that knowledgable. They won't know the difference between the cards or know the difference between a class 0, 2 4, or 6 (apparently btw, HD7s are coming with class 0 or 2 cards). Theyt'll see something cheaper and buy it, and then when they try to put it in their phone, will wind up railing against AT&T or MS.

Re: Samsung Focus - usable SD card specs?

Ppl are not that dumb (ok, maybe bought a SD card instead of microSD is just a mistake instead of not knowing the specs). But if you bought a 2GB or 1GB microSD, you know what you're buying and will still work fine with the phone. There is no such thing as 8GB or 16GB of microSD cards. The difference between microSD and microSDHC is simply size differences (and maybe a little bit faster for microSDHC cards). That's all.

Re: Samsung Focus - usable SD card specs?

I received my Adata 16GB microSDHC class 6 today and tested it with the previously mentioned gold standard software.  I am happy.

 

15476 of 15476 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 8.73 MByte/s
Reading speed: 17.2 MByte/s
H2testw v1.4

 

I also stopped by my local BB today and they were selling a 16GB microSDHC class 2 drive for $99.  That is almost criminal.  My class 6 cost me $51.

" Will the external MicroSD card be removable with out hard reset of the phone?

Thank you for your inquiry. Hi. Yes I totally understand exactly what you mean by the external Micro SD card slot. And yes the external micro SD card of your phone can be removed. Even if you don���t perform a hard reset, you can remove it. All you need to do is to turn off your phone, remove the SIM card and then you can remove the SD card. And if you have the user���s manual with you, you can double check how it is done. For further details regarding this phone, we advise you to visit our website www.samsung.com to check for other specifications that you may enjoy with this phone. Thank you for your continued interest in Samsung products. Sincerely, Technical Support

Re: Samsung Focus - usable SD card specs?

Two issues the above Samsung answer didn't address:

 

1. When you remove your SD card, yes, you don't have to hardreset the phone. But what Samsung didn't tell you is that the phone won't functioning until you either put the original SD card back or hard reset the phone. It has been confirmed.

 

2. The SD card you take out is not read/writable on other phones or PCs. So, it is not like you can take the card out and start copy music and movie to it. If you somehow modified the card, you will likely lost everything and need to hard reset your phone.

 

The SD card is married to your internal storage as part of the storage parition. It's like you take one of the hard drive out of a RAID0 array and expect your RAID to conitnue funtion as normal (it can't).

Technically the SD card IS a raid device - JBOD is how MS puts it, it spans that the internal 8gb and whatever you install in the slot. If a 32GB you would have somewhere close to 40GB available, minus the over head. Most other other phones handle the sd card as a seperate storage device

Jeff...

 

This is all well and good, except for the fact that when I purchased the Focus yesterday, your AT&T rep told me that he had no cards which could be used in the phone.  He went on to tell me that he had gotten an email stating that he should inform his customers to NOT put ANY microSD cards into their phones at this time.

 

That makes is sorta difficult to insert a card into the phone before you power it up for the first time.

Re: Samsung Focus - usable SD card specs?

I am not really sure what is going on here, but if you feel like trying, it is not critical that the card be inserted before the first time the phone is powered on, but it is that you format the card in the phone with the phone powered off.  Just follow the procedure.  It would appear that there may be some people who are still finding that their cards do not work.  I have no idea what that issue is.  If you have a good card though and you have tested it out for authenticity, I do not think that you will have any problem.

Re: Samsung Focus - usable SD card specs?

But format the card is more than just format. It hard resets and you lost everything on the phone. So, it is a hassle to put in a card after you have setup the phone.

Re: Samsung Focus - usable SD card specs?

For the "official" word, you should refer to the Microsoft Support site:

In short: some cards will work well while others won't due to performance characteristics.  The "Class" system is no guarantee.  To be assured of a good experience wait for the release of cards that are "Windows Phone Certified".

Re: Samsung Focus - usable SD card specs?

I opted to spend the cash for the Kingston 32GB Class 4 chip, which I purchased directly from Kingston.

 

test results:

 

Warning: Only 30591 of 30592 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 4.56 MByte/s
Reading speed: 16.9 MByte/s
H2testw v1.4

 

I performed a hard-reset on the Samsung Focus with this card in it (took all of 6-7 seconds) and it is reporting 37.07 GB Total storage with 35.04 GB Available.  I haven't really loaded anything on the phone yet, so I can't say that the memory is performant, but all signs point to being able to use the chip.

Re: Samsung Focus - usable SD card specs?

From XDA:

 

Over at XDA, emjee87 has been compiling a list on what microSD cards are reported to work with the Focus/WP7. This is because AT&T has gone back and forth on if SD cards should be installed and if so which ones, etc. Remember that this list is a work in progress so we need to see what happens as the cards get filled and used more often. You can also see that people are reporting issues, with some cards not working at all, some slowing down over time and some causing reboots so this is a real issue. So bear in mind that Windows Phone is only a few days old in the US this has to be treated as a rough guide but it’s better than what AT&T has told us (which is nothing):

Confirmed Working(Data remains after soft reset):
Kingston
Kingston 4GB Class 4
Kingston 8GB Class 4
Kingston 32GB Class 4
Microcenter
Microcenter 16GB Class 2
SanDisk
SanDisk 8 GB Class 2
SanDisk 16GB Class 2
SanDisk 16 GB Class 6
Currently Unstable/Unsure:
SanDisk 32 GB Class 2
Confirmed Not Working(Data gone after soft reset):
A-Data
A-Data 4GB Class 6
A-Data 16GB Class 6
Lexar
Lexar 16GB Class 6
Transcend
Transcend 8GB Class 6

Re: Samsung Focus - usable SD card specs?

I can confirm that the Kingston Class 4 16GB Micro SD card will work as well. I have 22GB total space and 15.88 available after loading several GB of music onto the phone. The phone will soft reset and turn off while retaining data. I have even turned off the phone, removed the SIM, SD card, and battery, reinserted everything and the phone boots up normally retaining all my data.

 

A few notes... The card came from Buy.com for about $35 shipped making it one of the larger, faster and cheaper cards available that works with the Focus. The card comes formatted for FAT32. There was some speculation that cards in other formats may cause the reset issues.

 

After purchasing the phone, I inserted the memory card and performed the "Hard reset" by pressing "Down" "Camera"and "Power" buttons. This booted the phone into the "download mode."

 

The phone was connected to my computer at the time, and when "download mode" was activated, the computer detected new hardware and attempted to install a similar diver/utility program that was produced for Samsung feature phones. I left the phone in download mode for over an hour then pulled the battery and restarted the phone.

 

At this point the phone was only registering the factory 8GB. I reset the phone through the "About" menu in "Settings"

 

After the reset, my phone registered 22GB of space with 20GB available. I loaded as many songs as I could find to test the SD card. After I got to less than 16 GB of free space I figured I had to be using the SD card's memory. I'm only about 1/3 the way through downloading my songs so I will have more updates if anything changes. Right now the system is stable.

I too confirm Daniel's assertion. Even I got my Kingston 16 GB from Class 4 from buy.com. No issues in using it in my Focus.

 

I saw prubins posting on my Windows Phone. But its browser didn't allow me to reply on the phone. So I had to wait till I came home.

Re: Samsung Focus - usable SD card specs?

I'd previously posted about having good luck with the Kingston 32GB Class 4 chip in my Focus.  I did indicate that I hadn't really loaded anything yet.  Well, now I have (tried) with pretty dismal results.

 

I was able to sync about 8-9 GB of music using Zune, and then my sync essentially stopped.  Instead of sub-second time to sync a song, it was taking minutes per song.  If I stopped and started the sync, it would synch 1-15 songs quickly, then go back to taking minutes per song.  Many others have reported this exact experience at http://windowsphonesecrets.com/2010/11/08/att-alert-do-not-install-microsd-in-samsung-focus-yet/ .

 

Now, just using the phone for normal operations appears sluggish.  Installing apps takes minutes when it use to take seconds.  Many times, unlocking the phone and swiping the screen upwards to reveal the home screen takes a couple seconds for the phone to respond. 

 

I'm not sure if I'm just being overly critical at this point, but I can say with certainty this is not the experience I want on a daily basis.

 

As a test, I removed the 32GB chip and tried to hard-reset the phone to the original 8GB.  Wow, what a mess.  I thought I bricked my phone for about an hour as I tried endless resets, battery removals, etc.  Search google for "samsung focus" and "download mode" for a preview into the fun times I had.

 

I eventually stumbled across something that made my phone an 8GB phone again and the phone was a responsive phone again.

 

I still debating on if I want to put the 32GB chip in again and hope that some software patch resolves the performance issues, or stick with the 8GB and hope that Samsung/ATT/Microsoft figure out a way to add the chip later without loosing any of my existing data.

 

I know we're only a week into this, but cripes... this was a National rollout, not some limited beta program.
