As a thanks, Andrew, I thanked you with a thanks.

Thanks.
[Focus General] SuperSport:
But, it was only 936. ;)

Hopefully, after the NoDo update, those cards will work. Unfortunately, for the time being, you have a paper, umm, I mean Stamp weight.

32GB+ C4 = ?

x - 16GB C6 = Stable

32+GB C6 = ?

[Focus General] OklaPony:
I suppose you're referring to your specific experience here? My Lexar 16/C4 was a bust.
[Focus General] kawgirlval69:
just refer to the first page and the other peoples experiences for the correct answer okla pony....
[Focus General] mKTank:
Based on observation. Didn't see anyone complaining about 16GB C4 until now. Hence the "???" I suppose.

I wouldn't trust the OP if I were you. A handful of the cards on there work perfectly.

[Focus General] OklaPony:
Whining? Who's whining? I posted about my issue with the Lex C4 card back in January which appears to be before you "showed up". Perhaps it's just a simple oversight on your part and you missed it as you read the thread. No big deal. Maybe the Lex would've worked after an update or two... We'll find out eventually.

[Focus General] mKTank:
Yeah, I didn't read the whole thread.

Hence the "???" ...

Don't get defensive, I wasn't attacking you.

Also is it me or is Board Express faster all of a sudden?

Sent from my Samsung Focus using Board Express
[Focus General] OklaPony:
Well, here's what you posted initially:

Attack would no doubt be incorrect, abrasive is probably more accurate... particularly the "whining" quip. Now that you've edited your original post, neither really applies and thanks for changing it.
[Focus General] mKTank:
Yeah, I was in the middle of a carwash, wasn't really paying attention. I changed it before you replied in the hopes that you wouldn't have read it yet.

What card are you using nowadays?
[Focus General] OklaPony:
None, zip, zilch, nada.

I decided to wait for certifications, updates, etc. before jumping back into the Focus expansion card game.
[Focus General] mKTank:
Well kawgirl's Samsung MicroSD seems to be working for everyone.

Personally I use an 8GB Lexar C6 and it works nicely. But I don't know how much you like Lexar after your last bit of experience with them. :D

I'm going to go ahead and say, though, that the Focus does perform a bit faster without a card. Understandable, I suppose, but damn it. I wish it just shipped with 16GB+.
[Focus General] enigma00:
My 16GB microSD card that came with the Motorola Droid 1 seems to work well. It's unbranded, but it is a class 2 card made by Toshiba.

It says "C16G" and "Japan".

Information

Hello all:

If it helps, my wife has this straight from live chat at Samsung tech support, in writing. The only cards currently "approved" (Samsung's words, not mine) are Sandisks, class 2 - in 8, 16, or 32 GB. He said must be Sandisk, must be class 2.

Hope information is helpful. Transcript below:

info: Please wait for a Samsung Agent to respond.

info: You are now chatting with 'Parkin'.

info: Your Issue ID for this chat is LTK4380658771X

Parkin: Hi, thank you for contacting Samsung Technical Support. How may I help you today?

DC: I know you are probably sick of this question. I brought my husband a Focus because it supposedly supports additional memory. He is legally blind and needs toe extra memory to run a proprietary speech program on the windows 7 phone platform. The lexar card I got crashed the phone. Is there ANY card that will work? I hate to return the phone.

Parkin: No problem, I'll be happy to give you all the support you need.

DC: thank you

Parkin: You're welcome.

Parkin: I understand that you what to know about the memory card which is supported by the focus phone. Am I correct?

DC: yes, I need to know what card to use. The Lexar card that was supposedly OK crashed the phone

Parkin: No problem, the memory card which is supported by the focus phone is Sandisk class 2.

DC: Thank you. Any GB? Like 8, 16, 32?

Parkin: You can extend the memory upto 32Gb.

Parkin: You're welcome. Is there anything else I can assist you with?

DC: Thank you VERY much

Parkin: Is there anything else I can assist you with?

DC: No, thank you

[Focus General] kawgirlval69:
i guess parkin reads from a manual and has not met any of the scenarios in real life huh...
[Focus General] SuperSport:
I have to admit, this late in the game, it's surprising to hear that from a tech support rep directly at Samsung. Samsung needs to update their database of phone issues for their tech support people. Parkin never even mentioned the fact that it needs to be a Windows Phone 7 Certified Card.
[Focus General] kawgirlval69:
yes that is something else parkin missed....

the wierdest thing about this whole sd issue is the fact the hd7 comes with a sd card... now it is sealed but there is one there that can be removed...it is a 16gb sandisk class 4... puzzling how it works so well in the htc and not in the samsung...
[Focus General] SuperSport:
I'm thinking it's a combination of software and hardware, but hopefully, software can make it work.
[Focus General] AmFuzzy:
Sandisk SD cards

Stop fooling yourselves into thinking that Sandisk cards work...or any other. I've tried so many it's not even funny. They all "appear" to work for awhile then strange things start to happen...like random reboots, resets, then stop working all together. I've given up and have just gone to using the 8Gb in the phone until Samsung or MS make it official which cards will work. It's not worth the hassle. I just wish they figured this out and release the phone in various storage sizes. I love the phone...wish it had a nicer back cover, but overall love the phone.
[Focus General] FishFaceMcGee:
I've been using the 16GB Samsung Card (that's been linked in this thread numerous times) for about 2 months now with zero issues.
[Focus General] JamesAllen:
SanDisk

Also using the SanDisk 16GB Class2 for 3 months with no issues.
[Focus General] SuperSport:
+1 Maybe a little extra lag, but I'm thinking without the card it also lagged a little.

NEVER a reboot or data loss though.
[Focus General] kawgirlval69:
then why hasnt there been a complaint on the 16gb samsung(does fit the any other statement) or the 8gb sandisk...
[Focus General] mKTank:
+1 for me.

Just like you said, it gave a little bit of icon lag every once in a while. But stability wise, no complaints. Only reason I switched to a C6 is because of the icon thing, as well as the alarm tune skipping and being choppy.
[Focus General] enigma00:
About 14GB left on it with 0 issues so far.
[Focus General] kawgirlval69:
let us know when you get it over half full to 3/4 full.... thats where the issues seem to arise...
[Focus General] joker79507:
I have a PNY 16 gb class 4 (i think) micro SD card and it doesnt work. I saw that it was on the list as compatible but every time i format it then soft reset my phone i lose all data. I will be honest, i didnt read every page in this topic to see if someone else had the same problem but the phone reboots fine without the card, even when data is loaded, so is it safe to say the card is the explanation?
[Focus General] PaullikesWINMO:
Safe to say it's the phone! :eek:
[Focus General] joker79507:
Really? So i should take it back and get a new one?
[Focus General] FishFaceMcGee:
If it works without the card, then it's the card. The only card "proven" to be reliable by being used by multiple members here is the Samsung card. However, due to the unreliable nature of SD Cards, at least to the extent that WP7 utilizes them, there is no guarantee any card will work.
[Focus General] joker79507:
Ahh ok, so then it is the card. Dang, that sucks, maybe i can reformat it and use it for something else. Thanks for the advice. I will look into getting a samsung card then. Is it safe to assume they sell those on the samsung website still or did they pull them off once everyone started complaining about sd card issues?
[Focus General] FishFaceMcGee:

WINTEC 32GB Micro SDHC FileMate Mobile Professional SDHC Model 3FMUSD32GBC10-R

Just picked up this 32GB Class 10 memory from Newegg and it has been perfectly for the last week in my Focus. Decent price at $83 for 32GB and confirmed working.

Hope that helps.
[Focus General] FishFaceMcGee:
How much space are you using?
[Focus General] Schindawg:
According to Zune I have total space used 5.01GB with 32.55GB free. Man, I thought I loaded up a ton of my favorite music, but I guess it is a big card! Have also downloaded/installed several apps/games without a problem. If you want me to "stress test" it, I could fill it up with a ton more music.
[Focus General] FishFaceMcGee:
You're not using the card until you're over 8GB.
[Focus General] Schindawg:
Ok. I'll try loading up some more music and report back to you guys.
[Focus General] jaraya13:
This is my exact same case. And I have only 5GB free. Regards.
[Focus General] Schindawg:
Ok. I just sync'd a bunch more music and podcasts across. Now Zune saying 14.26 GB used and 23.30 GB free. Messed around a little, played some music and loaded up a few games. So far so good but I'll report back if my micro SD fails. But, looking promising so far.
[Focus General] kindongo:
Where did you get the Samsung card?
[Focus General] lungothrin:
I've searched alot and there's no such a thing as "Sandisk 16gb class 6" , there's a sandisk "class 4" which is unfortunately sold out everywhere. if there is a class 6 variant available please provide a link or something.

I just got my A-Data 16gb class 6 today and had the same problem as others reported, worked fine on the first boot but after a reboot the phone shows 15MB as total storage, very disappointed!!!
[Focus General] eknutson:
So I searched, and came up empty. Color me embarrassed: I turned off my phone and popped the card only to find it's a class 4 *roll eyes* Sorry guys!

On the plus side, after popping it back in and turning on the phone everything was right where it was supposed to be data-wise :)
[Focus General] cwiley2566:
Kingston 16gb class 4 is still working working as expected. On and off +10 times and no reboots. Agreed the marketplace seems sluggish at times though or won't open. Just loading then back to start\tiles.
[Focus General] jro2020:
don't sweat it. That is happening for me with no extra micro sd card installed
[Focus General] Phiresun:
Been using 32gb Sandisk Class 2 bought from Amazon bulk packaging since 11/8. I have only soft reset my phone once since having it. I noticed my alerts for sms/ and email were coming in muffled and low in volume. I almost had a panic attack thinking my phone just died on me. I did a soft reset and all was fine again. I am using about 14gb right now adding music and apps everyday wirelessly and through usb. Keeping fingers crossed it last.
[Focus General] emjee87:
I've experienced the same issue after downloading/installing apps, marketplace won't load. also had it happen on different apps, although at the moment i can't remember which ones. A soft reset solves the problem for me, but it's definitely in need of a fix
[Focus General] MKohlman:
Sandisk 32Gb Class 2

just to add data to the list:

Bought a Sandisk 32GB from the ATT Store and Samsung Focus Accessories display and have been running it since Monday Morning. These are the things I've noticed so far:

I am seeing random reboots (about 1 -2 times a day) interestingly though it never seems to have happened when recharging/plugged into external power. Only when it is sitting unplugged and idle.

Of those reboots about 1 time out of 4 or 5 the unit will come up in default mode. A soft restart always brings everything back and there is no evidence of data corruption (yet).

I have about 18 gig of data loaded on the device so far.

For me this is not yet annoying enough to pull the card deal with the lessor storage restrictions, but it would be nice to see fix soon.

- MEK
[Focus General] Paolo01:
My A-Data 16gb class 6 which I installed on day one, formatted with the power off 3 button format just dumped today. Needed to turn it off for an airplane and it restarted with 15MB. I pulled the card out, reformatted and all is well. (I feel like my old reformatting every few days with Energy now :-) )

Ok, here is the funny thing. I had power cycled the unit before with no problems. Still trying to figure that one out.

Ok. So write that down as another A-Data does not work data point.
[Focus General] Mallux:
I installed an 8Gb class 4 Lexar micro SD and it appears to be working.

The one i got was from office depot. They're usually on sale for like $14.99, so not a bad deal
[Focus General] evnow:
Registered just now - info on WP7 cards brought me here (from at&t forum).

Reading about this on various forums/kb articles etc etc here is what I can say.

The class of SD cards or even make says little about compatibility. What WP7 needs to quickly load apps is high random access speeds. The class only tells bulk data transfer speeds used by cameras. Totally different things.

A slow card will appear to work well in the beginning - the apps used would still be on the fast internal memory - but may start loading apps slowly or might even timeout while loading apps later on when the apps get stored on the inserted microsd.

If someone is willing to brick their cards testing this is what I'd suggest.

Before using the card load a lot of apps and check how the apps are working (benchmark).

Get all the info about the cards before putting them in - make, batch, date, oem manufacturer, store where bought etc etc.

Once you put the card in the phone and reset to see the full storage, load it up with a lot of music/videos etc. So in Focus, load up much more than 8 GB. Then install a lot of apps. See how fast they work - compare to benchmark.

If the card works well, let us know. We can try to buy the cards from the same shop and hope we get the same batch.

Here is a fascinating account of someone trying to chase bad cards marketed by Kingston.

[Focus General] KonAitor:
Has there been any word on being able to backup apps, email, txts, along with music and vids? I want to add my old 8GB card, but don't want to re-download and re-sing in to all the apps.
[Focus General] rruffman:
Testing your cards might be the best answer to help sort out the issue

Hi

i have installed a sandisk 32gb since monday never had anyone of the problems people have been reporting. i did the reset from the about screen to format my phone and reading most posts its seems that people who format the phone this way seems to not have problems maybe its the "press power, camera and volume down" method that causes a problem?? or could alot of the cards have bad sectors as reported alot do we just never know it because devices never used a sd card this way before... i sudgest people who have problems take out the card and run this test program on the card to see if the card has bad sectors.
[Focus General] emjee87:
Good to hear it's working out okay for you. I believe there has already been a post or two from people who tried it your way and eventually had the same issue. It very well might be down to each individual card, in which case it's going to be an even bigger gamble picking up an SD card at this stage in the game. For the time being, I think it's best if we leave the 32GB SanDisk card in the "unstable/unsure" column because so far there have been too many people reporting failure here (and elsewhere with this card) to chalk it up to bad luck.

Hopefully your card stays functional, but if there's any changes for you, please be sure to let us know
[Focus General] jeffgeno:
I just got a SanDisk 32GB Class 4 card in the mail from NewEgg today. I ordered the class 2, but got that instead. I wasn't aware they were making them yet, but it came in packaging stating it's "For Mobile Phones." I popped it in my Focus, did a hard reset from the About menu, and the memory popped up as working. I've installed stuff and reset the phone a couple times and haven't had any trouble. It's only been a few hours, though. I'll keep an eye on it for the next couple weeks.
[Focus General] racedout:
Sandisk 16g

I bought a Sandisk 16 gig class 2 from the AT&T store hoping that it would work with the phone with no problems, and it did for about two days. Then the phone started resetting out of nowhere, marketplace started having freezup problems, and then this morning I could not access my contacts or my account settings for windows live at all. Just got kicked out to the home screen. Even after multiple soft resets, same thing over and over. I had to pop out my card and reformat using the option on the about screen. When I rebooted I had 15.? available memory, and this was not correct. I then hard reset the phone using the key combinations and now I have 8g and everything is working great. Guess even Sandisk 16g Class 2 can have problems...
[Focus General] alvinswim:
Yep, I had that problem with my SanDisk 16Gb Class 2 on Monday Eve, to Tues. I posted earlier. it just doesn't like it. On the otherhand I've had my meager SanDisk 4GB Class 2 and since Wed its been working just fine. not too much extra space but its rock solid.. I'm thinking of getting a 8GB Class 4 or something. that might work out.. who knows until they release a bug fix.. but who knows how long that'll take... lame
[Focus General] marcoma:
It looks very much like the class rating has VERY, VERY little to do with the card working or not - (there is a Microsoft KB article about it somewhere) It's all about random access speed and this seems to vary greatly from card to card.

There are some reports of the Sandisk 8GB class 2 device being very stable with no problems while virtually all other 16GB and 32GB cards (including class 4) throw the occasional fit and reboot the device.

The standard 'put the card in and reboot' test doesn't really show if the card is actually dependable.

The SD Card will be part of a JBOD architecture of the phone - so the filesystem will span the internal and SD card memory (which is why one shouldn't remove it once it's in - you'll break the filesystem). A lot of times one would have to sync >8GB content to the device to actually cause sustained, random IO to the card and this is when the spook usually starts... random reboots, default resets showing 15MB memory which go away after a simple reset only to show up 20 hours or so later again.

So while people might see the 'correct' memory displayed after putting in a 16 or 32GB card, right now I wouldn't bet on them not having an unstable system once they really use the added memory.

It also means that I'm not too hopeful on a software patch for this (or at least a patch that wouldn't decrease the overall speed of the device to allow higher IO latency) - I am however hopefull to see a list of specific SD cards that have a high enough random IO throughput to be safely used...
[Focus General] pigue:
32 gig Class 2 from AT&T. Had to wait because to install since the sales guy said we were not supposed to try yet. OF course I did it as soon as I got back to the office. reformatted from the about tab. No problem ever since. works flawlessly and have rebooted at least 6 times since then. I will report back if it does start acting up. I only have about 5 gigs of data on it so maybe it has not hit the card yet...
[Focus General] paschott:
Same here. Kingston 16GB Class 4. Using more than 8GB. Have soft-reset several times with no issues. Marketplace got wonky at one point, but soft-reset cleared that. I think it got hung up on a download or something. In any case, still going since Monday. (Admittedly a short test period, but so far I'm still running. I'll likely load up one or two of the larger trials to see what happens, especially now that I'm into the sd memory space.)

Hoping that this is a patchable issue, but time will tell.
[Focus General] rruffman:
Usig more than 8gb before you start having problems

after doing some testing i have found that if you have used up well over 8gb this is when problems start happening if you are only border to 8gb seems to not have any problems, i have tried under 8gb no problem, just at 8gb or alittle more, no problems, well past 8gb like 10 or 15 gb used then this is when problems start happening the freezing, reboots etc...
[Focus General] jaraya13:
I got it from eBay. From a seller Nikolai or something like that. This is the exact same item I bought:

[Focus General] Schindawg:
My WINTEC card is still happy, and I see Newegg just dropped the price to $78.
[Focus General] kawgirlval69:
when you get the card just a bit over half loaded(the card) watch it closely... ive noticed this is the point of unstability with the cards ive tested...
[Focus General] Kreigz:
Just for clarification ...

Different forums seem to refer to the problems with the Focus and SD cards differently.

Are we talking about the phone restarting and coming up to a sorta-setup screen and a manual shutdown and restart fixes all problems without any loss of data (my phone)? Or are we talking about the phone restarting and coming back to setup with a near total loss of storage space and data with no fix?
[Focus General] FishFaceMcGee:
Here's the thing: in most cases, if you start getting issue 1 it eventually becomes issue 2.
[Focus General] Kreigz:
Thought that might be the case. I've been having issue #1 since Nov 7; got the phone on the 6th with a 32 gig SanDisk class 2 card at ATT. They told me they specially ordered the card for the phone.

I have, on the average, 3 restarts a day. So, no loss of data. Hoping NoDo fixes the problem.
[Focus General] TOA Duck:
I am hoping that ATT will add something to the update to fix it. Maybe thats why ATT will take longer to push the update. :D
[Focus General] FishFaceMcGee:
If that's the case, I would forgive them for the delay. It's not happening, though. Samsung isn't even listing microSD card support as a feature of the phone on their site (though I'm not 100% sure they ever did) so I'm all but figuring they're not doing anything about it and just hoping the issue will "go away."
[Focus General] lifanus:
Installed PQI 2GB Class 2 MicroSD, works fine, phone now have close to 10GB space... Not a lot of storage gain but it works!

Overall performance seems not affected, start-up/shutdown all pretty snappy. Soft Reset couple times with no problems.
