What brand was the card you were using? Also, did you follow the instructions for inserting a sim card as per the Focus manual? Thanks
[Focus General] alvinswim:
SanDisk, and yep.. I followed the instructions, Format, etc etc. 20GB or so was available.. and everything was normal for 12 hours or so.. then.. BAM.. it started crashing,, and then all settings lost.. and space of course.. it was like it just became corrupted.

I wonder if the mircro sd was loose or something. or dirty contacts. dunno.. I may try it again tonight. or just buy a faster class card
[Focus General] emjee87:
Sounds good, let us know the results if you try the SanDisk again, as most people have posted that they had good results with them.
[Focus General] ryotgz:
Not working:

A-data 16GB class 6

A-data 4GB class 6

EDIT: let me rephrase "not working". The phone will recognize it and work fine until your soft reset. Then all settings, etc are gone.
[Focus General] ryotgz:
I just tried my Kingston 4GB class 4 and it worked.
[Focus General] surfnet:
WORKING : Kingston 32GB class 4

I first tried volume down, camera and power button. That gave me the download mode window and it lasted for about 20min before I gave up and took out the battery. then the phone came on fine without the new memory. I then went to settings>>about>>reset and that worked perfect. I have re-setup my phone with apps and exchange.. then I powered off (goodbye) and then on twice.. all my data is still there and it says I have 34.17 gb of free space ..using 2.36gb

but 2.36 + 34.17 = 36.53

where are my other 3.47 gb?:confused: I suppose they are the OS:o

but the world is great.. a windows 7 focus with 32gb card.. AWESOME!:D
[Focus General] RustyGrom:
From SanDisk's site it doesn't look like these come with adapters so that's not necessarily a red flag.

The rest of the things you mentioned are though.
[Focus General] jeffgeno:
That's exactly the one I got from NewEgg.
[Focus General] hector_huerta:
What about the Kingston 16GB class 10? anyone tried that?

they sell it directly from amazon and is legit, because is listed in the Kingston webpage
[Focus General] illipro:
Using Patriot MicroSD 16GB Class 2. Picked up at Local Compusa Store. Working fine so far. using now over 11GB

Will update.
[Focus General] AllTheWay:
Yeah somebody hooked you up with Post Office discount more than likely.
[Focus General] RustyGrom:
I stopped by the AT&T store and they had a 32GB kit in stock. It's definitely the Class 2 card seen on Sandisk's site. It comes with the card, a USB adapter, and SD adapter. Not too bad of a price for $140. Even better when it's half off and $75 including tax :)

So far it works great. Just as speedy as before and I've used ~14gb so I'm certainly onto the card.
[Focus General] lazyn00b:
PNY 8GB Class 4 seems to be working OK after reboot.
[Focus General] RustyGrom:
An update with the Sandisk Class 2 32GB card purchased from an AT&T store....

My phone has now reset itself twice since this morning. The first time I was in IE and the 2nd time I had checked my email a few minutes ago but it was actually off at the time. The 2nd time it came back with no data. I wasn't even touching it and it was sitting flat on my desk when it did it. Rebooting brought my data back thankfully.

If it keeps this up, I'm taking the card back to the store and waiting til the situation improves. Definitely not acceptable.
[Focus General] emjee87:
Just out of curiosity, what is this 50% corporate discount people keep bringing up? My company is part of AT&Ts premier business plan and I'm signed up for that, but I don't see anywhere on their premier site that shows 50% off on accessories..
[Focus General] TOA Duck:
the 16 gig class 2 sandisk id still working beautifully in mine. 1 week now.

Bought it from Best Buy
[Focus General] emjee87:
Just bit the bullet and purchased that card from Amazon, hopefully I see the same results. It's in bulk, but the seller had like a 99% rating and the ones in retail packages didn't apply for Amazon Prime, so...fingers crossed.
[Focus General] RustyGrom:
Engadget posted a good summary of some of the issues.

http://www.engadget.com/2010/11/17/windows-phone-7s-microsd-mess-the-full-story-and-how-nokia-ca/

Most of it we already knew but interesting nonetheless.

One of the perks of working for a massive company.
[Focus General] godfa7h3r:
Here are my findings...

Kingston 32GB class 4

This card worked beautifuly right out of the gate. All storage was recognized after a hard reset. However, after a few hours and after it exceeded around 10GB of storage filled up, the phone began freezing and crawled down to an unresponsive state. I was forced to remove the card and RMA it.

SanDisk 16GB class 2

This is what I replaced the Kingston with. This card has been working flawlessly for the last 9 dates. No freezing, no slow down, even after filling the phone back up with 10GB of data.
[Focus General] TomH123:
Lexar 16GB class 2

Purchased directly from Lexar webpage. Has worked flawlessly for over a week now with about 15GB of music downloaded. No freezing or lockups.
[Focus General] jeffgeno:
Any random reboots for you two with the 16GB cards?
[Focus General] ninjaquick:
36.53 looks about right, remember: The manufacturer defines a GB as 1,000,000,000 Bytes, while an OS will define a GB as 1,073,741,824bytes (2^30) so: 32,000,000,000 / 1,073,741,824 = 37.25 GB. Any further "capacity loss" is probably swap file space and system reserved space.
[Focus General] dhan911:
Have you tried going over the built in 8GB? If you don't have enough songs, just get some podcasts to fill it up
[Focus General] jeffgeno:
Here's the word directly from SanDisk. They are now manufacturing Class 4 cards.
[Focus General] RustyGrom:
Cool. Thanks for doing the leg work. NewEgg needs to update their product descriptions!
[Focus General] peterfnet:

[Focus General] Andrmgic:
They pulled the list earlier today.

Maybe someone at microsoft or samsung contacted them..
[Focus General] webdev511:
Yes contacted them to make sure they only post the new "obtainable only through wireless carrier & Microsoft channels" part number. I mean where's the profit if you can't tell someone you MUST buy this PN and then let them buy said PN just anywhere?

Also I got my SanDisk 32GB microSDHC from B&H today. It's in full SanDisk retail packaging and is marked as Class 4. I won't be testing this with my Focus as AT&T still has crap coverage at my house. My permanent WP7 is going to have to wait until I can get one on Verizon and I'll put the 32GB in that one.
[Focus General] TomH123:
I haven't had a single reboot that I haven't initiated myself. Those were to test that the card still looked good after a reboot.
[Focus General] mcpell:
I've been following this thread for a week or so now as I am interested in getting a memory card for my Focus. I've been holding off to see how all this pans out.

I haven't been running with any extra memory in my phone and have had to do a soft reset about three times. Twice was while I was scrolling around in the marketplace and the third time was in Zune.

My point is that I don't know that we can chalk up all of the soft resets required due to locking up and/or slowness in the marketplace and other places simply because of the memory card you are using. I'm not using any memory card and have had a few issues.

Just some input as to correlation between issues and memory cards, or the lack thereof.
[Focus General] RustyGrom:
mcpell, I hear ya but the difference is that you initiated those soft resets. With a memory card, it may just randomly do it on it's own and occasionally will come back in a clean state with none of your data, requiring that you soft reset again to get your data back. I just installed my card last night and it's rebooted on it's own 3 times today. I have noticed some other quirks that I hadn't seen before as well.
[Focus General] wyvex:
Originally had a Scan Disk 32 GB card installed. Soft resets all day long. Enough that it affected battery life. I took that card out and replaced it with a Scan Disk 8 GB card. Working excellent now. No resets. No slowness.

Used a Nokia N97 to format the 32 GB card. Worked flawlessly to recover the card so it can be used in other devices.
[Focus General] jeffgeno:
I did the same thing last night. I'm going to RMA the 32GB card and pay NewEgg's 15% restocking fee.

RadioShack has the 8GB SanDisk cards on sale for $20. I figure that's cheap enough to throw it away when the approved 32GB ones come out.
[Focus General] malimal:
Lower class Rating may be better..

From the Engadget article yesterday..I found this to be interesting...I ordered the Sandisk 16GB Class 2 on Tuesday from Newegg..Should have it soon.

They also say not to go out and buy the lowest class card either..

[Focus General] tblowdermilk:
Returning back to the default

Can someone please verify this for me:

I had 2 Samsung Focuses (Focusi?). I purchased a SanDisk 32 GB Class 2 for each of them.

Installed the cards and performed a hard-reset (settings > about > reset).

The storage was recognized.

After a couple of days, both devices started having problems. Every so often, I would pick up either of the phones and notice that there was no data on it. It was if the phone was never set up. It also reported that it only had 15 MB of total memory.

I took both cards out of each device and performed another hard-reset (settings > about > reset).

However, both devices still reported only 15 MB of total storage.

I ended up taking them back to AT&T and getting 2 more.

Anyone know why that happened.? How come I wasn't able to soft-reset the devices and regain my original 8 GB of storage?
[Focus General] emjee87:
If you actually read the thread, you would know that there is a problem using external memory currently with this phone. You would also see that your card is listed as one of the problematic ones, and that a hard reset is usually in order. Please read before posting.
[Focus General] jeffgeno:
Camera, down volume, and power. That brings up a page asking you if you'd like to format whatever memory is currently installed. That's how I downgraded from 32 to 8.
[Focus General] tblowdermilk:
Interesting...Okay...I'm trying it, but no dice..

Just so I understand:

1. From the home tile screen press the camera button, volume down, and the power button?

2. Do you press them all together at once? Or do you press them in the above order?

3. Do you have to have an SD card installed for the menu to come up?
[Focus General] tblowdermilk:
Ahhh never mind...

You do it like this:

1. Power off the device.

2. Press and hold the camera, volume down, and power button.

3. The phone will boot and display a message: "download mode Do not turn off. It takes about 10 minutes."

Looks like my phone just hung on step 3.
[Focus General] tblowdermilk:
Okay...Now we got it...

If you press and hold Camera, Volume UP, and power...it takes you to "Download Mode"

It's very finiky...you have to really make sure you are pressing volume DOWN
[Focus General] fredskis:
Hi I upgraded my HTC 7 Mozart to 32GB using a Team class 2 microSD card and it has been running fine for about a week now.
[Focus General] Tempest790:
Been using a Sandisk Class 2 16GB card for about 3 days now with no problems. Everything still moves snappy.
[Focus General] JohnPalmer:
Day 11 with Sandisk 32GB Class 2 Card

I have loaded close to 12GB of music on my Focus. The device hasn't had any reboots or performance issues. My card was purchased at an AT&T store and installed by using the resetting feature within settings. I have about 1GB more of music to store on the card but there is no question I am using the memory on the card. I show total storage of 36.90GB with 24.50GB available storage.

On an unrelated note, I did have a hiccup in the marketplace yesterday where it hung for awhile and kicked me back to the start screen. I had to reboot to fix the issue. However, this is unrelated to the SD card issue as I have read on another forum that other Focus owners sans a card have experienced similar marketplace crash problem. I will report back if I experience any problems on the SD card front.

Out of curiousity, of those that tried the Sandisk 32GB card, did you have a case? Reason I ask is because the BodyGlove gel case fits very tight on the Focus and the slightest pressure near (not exactly on) the power button will cause the phone to reboot. If I had to pick at the design flaws of this phone is that Samsung should have placed the power button on the top of the phone and the micro usb port on the bottom (so that it could fit in a charging craddle).
[Focus General] serialtoon:
So yea, not sure if its related to the sdcard i have but it seems like it everytime i would load up the marketplace it would stall for a few minutes before letting me do anything. This started happening after i started to reach the threshold of the cards maximum space. Maybe a fluke or not but i am going to be using my phone without it and see if it changes over time. The card i was using was one of the listed "working". Kingston 8GB Class 4. Before i leave here, i also started having issues with the keyboard stalling when it was trying to "think" of what words it can replace my misspelled ones.
[Focus General] JohnPalmer:
Unfortunately, I spoke too soon. I was by my desk and an email came into my phone. The Focus lit up and stayed on for over 2 minutes. I have it on a 30 second shutoff. When I went to look at the screen, it was the default factory screen. I am not sure if the phone rebooted into this state. I performed a soft reset and got my information and settings back. Needless to say my card is not Windows Phone certified.

I have 3 weeks to take the phone back. The lack of additional storage is a deal breaker for me. Anyone have any idea how I can get a hold of a Nokia N8 to reformat my 32GB card if and when I get a Windows Phone certified 32GB card or if I have to return the Focus back?
[Focus General] salutti.net:
Just tried Kingston 16GB Class 10 but with no success :-(
[Focus General] dhan911:
I have seen the marketplace hung and crash thing happen on my Focus twice so far and I have not added any card to mine yet. I had to reboot both times to fix it as well. It's certainly not related to your 32 GB card.
[Focus General] RustyGrom:
If you bought the card from an AT&T store, I'd recommed just taking the card back there. If you don't need 32GB, you'd probably be best off getting a 16GB SanDisk card from the AT&T store. From all accounts, that card is completely stable.
[Focus General] JohnPalmer:
How true is that (re: SanDisk 16GB card)? Have people loaded it up with over 10GB of files to test the card's memory? My 32GB card was working well even with about 8 or 9GB of music files. When I went over 10GB is when I experienced the reboot. BTW, it was only one reboot. I haven't had anymore since (then again it's only been 11 hours). I will hang on to the 32GB card for more observation or until I can get a certified one. 16GB would be acceptable to me as I am coming from an 8GB device.

I was enjoying the hassle free experience of a new device and OS without bugs until this. I guess it is standard to accept these types of inconveniences when you want to be an early adopter.
[Focus General] FishFaceMcGee:
When I was using my 16GB, I was able to max out the phone for the day I was using it with only minor (strange stuttering at the end of songs) performance problems.
[Focus General] jeffgeno:
I think we need to put together three categories here.

1. Not Working - not recognized by the phone, loses data on reboot, etc

2. Unstable - keeps data after a reset, but experiences hangs and random reboots

3. Fully Working - no data loss, no random reboots

I can say from personal experience that the SanDisk 32GB Class 4 card is in group 2 and the 8GB Class 4 card is group 3. I put the latter in my phone two nights ago, loaded it up with 10GB of music and haven't had a single blip since.
[Focus General] alpine3823:
AAA PLUS for you 32GB working like Champ
[Focus General] JohnPalmer:
I went to the AT&T store and since they sold and installed the 32GB SanDisk card on the same day the Microsoft advisory came out, they agreed to take it back for a full refund. I decided to keep the card until right before the 30 day return policy expires. So far I only had one random reboot. I am hoping the 32GB certified cards are released for sale within the next 2 weeks. I am glad I loaded the phone up with files since I would not have detected the card's instability unless I had done so. I caution 32GB SanDisk owners that their cards may be working great, mine did for 11 days. However, unless you fill that card up with 10GB or more, you will not know whether your card can withstand stability issues.
[Focus General] kevinskocik:
My SanDisk 32GB Class 2 card has been working perfectly on my Focus. Everything is stable. Phone is extremely fast.
[Focus General] dhan911:
how much data (songs etc) did you put on there?
[Focus General] kevinskocik:
There's 10 GBs of music on here. Not too many photos or apps though.
[Focus General] JohnPalmer:
My 32GB SanDisk card was working flawlessly until my phone hit the 10GB storage mark. You should download some videos or podcasts to fill the card and see if you experience performance issues. If you don't do this now, you may expect some unpleasant bumps down the road.
[Focus General] dhan911:
would you mind adding a few video+audio podcasts to bump it to somewhere between 20-25GB and let us know the results?

Ditto.
[Focus General] alvinswim:
emjee87,

I wanna report that I have a SanDisk 8Gb Class 4 Working in my phone for the last week, multiple reboots, power off's, etc, etc all data retained.

can you also include more details such as

card SKU number

bulk/retail

how much total data was on the phone

how did you reset the phone
[Focus General] hyperzulu:
Kingston 16GB Class 4

So, I've been running the Kingston 16GB Class 4 card for a week and it's been rock solid. Just recently I went ahead and pushed a ton of content onto the phone for the sake of testing the stability of the phone once data started being written to the card. First note is that it seems the phone will write to a buffer when syncing. My guess from what I've seen is it's about 50MB. After that it starts writing directly to the card and that's when things SERIOUSLY slow down.

But it's not slower, it's simply SLOW. I know that I could write data to the card much faster than WP7, from my PC if it was hooked up directly. It shouldn't take ten minutes to write 65MB of data. This seems to be the case though. Pulling the data cord mid sync and reattaching it after a second seems to clear the buffer and allow another handful of songs to be written very quickly.

Even so, I haven't noticed any spontaneous reboots or slow behavior in the phone. I've played music that I suspect is on the first 8GB as well as music that I suspect is on the data card and it all plays smoothly. Where I have seen some slowdowns though would be when generating new content on the phone. For instance, making a quick HD video. To be honest, I didn't time it with and without the card, but I think without a doubt it is slower sometimes to get back to the live camera view after a video or picture is taken. I guess it depends on how long it takes the phone to write the data to the card.

So far though I think the tradeoffs are acceptable. I don't think I could live with random reboots or lost data, but some slight sluggishness in areas I use only seldom is OK.
[Focus General] Th3Commun1st:
I installed an old Transcend 8gb Class 6 SD card yesterday and everything seems to be fine. Restarted the device multiple times and I haven't lost my data yet.

Total Storage: 14.80 GB

Available Storage: 6.47 GB

Some of you who also tried this card... when were you seeing the issues appear?
[Focus General] emjee87:
Trying using more than the 8gb that comes with it and seeing if you get different results.
[Focus General] emjee87:
Like dhan911 asked, can you please provide us with how much data you have used on the phone? The rest isn't really necessary, people should be able to determine what is a sketchy source and what isn't, and what kind of packaging is probably fraudulent. However, it's very important to note how much data is being used as many people are only seeing issues after they have gone past the the initial 8gb of storage.

On a related note, I've going strong for 4 days now with a 16gb Class 2 SanDisk card, used all but 3GB and no problems at all.
[Focus General] JohnPalmer:
32GB SanDisk Class 2 Update

It's been 40 hours since my Focus rebooted after loading up the phone with close to 12GB of content. I have only had one reboot and since then the phone has been performing well. I am even playing back content I last uploaded to my phone and it sounds and plays as well as the first album I downloaded to the phone. I still have about 24GB of available storage. I will upload some videos to the card to test the stability even further. I am hoping my reboot incident was isolated but I cannot state is a 100% stable card because of the one random reboot.

I will post back when I have loaded another 10GB of content to the card.
[Focus General] Th3Commun1st:
I think I am... I've got 6.05 GB free...

UPDATE: Syched a movie and it worked fine. Restarted, still have all of my data. Lags for half a second or so after start up but nothing noticeable after.

Total: 14.8 GB

Free: 5.37 GB

16GB @ $79.99

If you click on compatibility tab, Samsung Focus is listed.

Are we to assume that AT&T did their homework and this is WP7 compatible?

If you look at the 32GB compatibility list, Focus isn't listed:

http://www.wireless.att.com/cell-ph...029&q_sku=sku4960229&q_manufacturer=&q_model=
[Focus General] dhan911:
can you try pushing it a bit further, like say only ~700MB or so free?
[Focus General] hyperzulu:
Blegh... I guess I spoke too soon. Phone doesn't reboot bu at times random parts of the phone lock up for a few seconds. At one instance the marketplace seized and it would boot me to the main menu if I tried to access it again. I think it's a shame. Guess I'll just pull this card and wait it out.
[Focus General] webdev511:
From what I can tell, the market place is just glichy like that. I guess buffering info for 3,000 applications isn't as stable as it should be.
[Focus General] RustyGrom:
Yea, that happened to me once when I didn't even have a card in the phone.
[Focus General] Th3Commun1st:
I don't have that much compatible content on my PC right now (I guess WP7 doesn't support Xvid?)

I tried a Kingston 16 GB Class 4 and had some serious performance hits while syncing (around the 10-12gb barrier) and while using the UI (screen would become unresponsive). I had screen response issues when I was using the phone without a card, but these seemed noticeably worse.

I went back to the Transcend and everything still seems to be working fine. Performance actually seems better than using the phone without a card, but it's hard to actually be objective with that.

Zune:

Used: 13.5 GB

Remaining: 770.2 MB (5% reserved)

Phone Settings -> About:

14.8 GB Total Storage

2.07 GB Available Storage

Data persisted across a device restart and performance still seems fine. My screen still ocasionally becomes unresponsive (still refreshes, but doesn't recognize input). To get control again, I have to turn the screen off and on using the lock button. Has anyone else been having this problem? or should I get a replacement?
[Focus General] sandrobber:
Idea

has anyone try to perform a full format on these cards before they put it in the phone and try reducing the byte size to eith the minimum or maximum size. perhaps their is not formatting of the card being done.
