Let's wait a little

I'd really like to see what happens to the class 2 32GB card over time as it fills up... I had no issues for a day or so, filled up some of the memory (in the end I think I had 25GB or so free) and all of the sudden the phone decides to reset... no data loss, but sometimes it would come back with default settings - off/on again and oh-wonder, all my data and settings are back.

To me this points to the card being the culprit (removed it for now) - just because it shows the memory and it will keep settings when you turn it off and on again doesn't mean the card isn't screwing with the phone / OS's stability... just give it some time - let me know if you experience weird reboots.

I just got my class 2 32gig scan disk card from amazon, powered down, opened, removed battery, inserted card, pressed three bottons, than two till i got "format"

my phone shows total storage 36.90, available 35.00

powered down phone, powered up and stayed the same

powered down and reset two more time and stayed the same

hoping it works ok, time to load up some music and vids
[Focus General] rhart20:
I installed an off brand class 6 16gb from Newegg. It's the RI-DATA one. It is a slow card with speeds more like a class 5 if there was such a thing but it works well. No issues after doing a settings-about phone-reset. No problems after a power down either.

edit: Scratch that. Trying to download larger portions of my music library causes instability. Zune sync slows waaaaaaaay down and the phone stops responding to screen touches. Looks like class 6 cards should be avoided.
[Focus General] Seed 2.0:
This tool doesn't detect my post windows phone 7 MicroSD card. I added one it can detect, and tried hot swapping it to my broken transcend 16GB class 6, but as soon as I remove it it clears the tool's list.

I read one these boards that a Windows Mobile 6.5 phone is able to reformat the Post WP& flash to a format the computer can see, thus reformat to Fat32 etc... ATT no longer has any Win 6.5 Mobile phones. They suggested I try non corporate store.
[Focus General] audichris9:
I'm using a Class 4 16GB Kingston. The system is recognizing the full memory after a hard reset and everything is working fine with one exception. I'm currently filling my phone with songs and the upload from Zune connected to my computer has slowed to a crawl. Anyone else having this problem?

Sandisk 32GB Class 2

Hello, signed up just so I could do my part and throw in some more results. I've been trying my Focus with a 32GB Class 2 Sandisk for the past two days, and it'll format fine, rebooting will keep the right capacity, and transfer speeds seem fine. But after a while, and especially if it's on or just been on a charger, the phone'll randomly reboot. So far haven't had this issue without the card installed for the same app and config settings, so, I'm returning my 32GB as untrustworthy. Looks like I might try the 16GB instead.

If it helps, I've been syncing over about 12 gigs of video and music, so, more than enough to be tapping into the card capacity when my problems start.

Patriot 16GB Class 4 working PERFECTLY!!!
[Focus General] Sebo1985:
For how long? With how much data on it. Give us more information, please!
[Focus General] SuperSport:
My status is still as follows: NO Crashes, Reboots or Loss of Data at all! I do have lag and the screen seems to not respond at times. I think it's a combination of SD Card, Low Power, Sensors, and Syncing, but not all at the same time. I don't think the phone sends enough power to the SD Card for access some times because the problem seems to happen more often when the battery is low. Just a guess, but I'm trying to pay attention to when it happens most. As I mentioned in a previous post, it also depends on how the phone is being held, or what it's touching. I'm still hoping a software update can fix all this.

Mine reboots fine, but it will not turn off when plugged in. If turned off, it will reboot automatically.
[Focus General] ITDRAGON:
what class is your card? it's printed on the card itself don't go by what you think you bought.
[Focus General] SuperSport:
According to the part number, it's a class 2.
[Focus General] OklaPony:
I tried a 16gb Lexar Class 4. It worked perfectly until I powered the phone down at which point I got the dreaded 15.73 mb status. I even tried the double formatting trick but it didn't work either so I'm sticking with the stock 8gb until the real thing is tried and tested.
[Focus General] Morriswindgate:
I can confirm that the SanDisk 32 GB microSD High Capacity (microSDHC) - SDSDQ-032G-A11M works in the phone. Although it is a Class 2 card there was not slow down or issues with the phone and it reads and writes files at a very fast rate.

I also tried the Komputerbay 16 Gig Class 4 card from Amazon. It showed that it was installed in the settings, but the phone would not allow it to be written to and it caused a definite degradation to the phones operation.

I am also waiting for a Locked Card flash tool and will update when I get it.

This is the best price that I found on the Sandisk card was $93.97 from the link below.

e-mail me at wefullen@sycamore.com for links
[Focus General] FishFaceMcGee:
1) How long have you used the card

2) How much of storage are you using? If you're not over 8GB you're not using the card.
[Focus General] xThe Enforcer:
I have 17GB left on my Focus. Heavy usage and 50+ apps/a few videos. Runs smooth, no problems. Never reset.

Froze once but I was transferring a video from Zune to my Focus so that's probably why but it un-froze right after.

No lie, GO FOR IT!!!
[Focus General] FishFaceMcGee:
If you're not using more than 8GB, you're not using the card.
[Focus General] xThe Enforcer:
Oh, so once I get to 14GB than the card will be used?

Thought the card integrated with the internal memory?
[Focus General] FishFaceMcGee:
I'm not sure that anyone is totally clear on how the storage works, beyond the fact that, when the card is bad or does not work perfectly, the issues don't start showing up until after 8GB is filled.

For instance, on the Kingston 32GB Class 4 card, syncing started to go extremely slow (10 minutes to sync a single song that was already at 192 Kbps) after the 8GB was full.

If you want to make sure you're stressing the card properly, I would make sure you get as much content as the phone as you possibly can.
[Focus General] abledanger:
Are you sure about that? Aren't the internal and sd card memory striped so it's seen as a single file system?
[Focus General] FishFaceMcGee:
Like I mentioned above you, I'm not sure anyone is 100% on how the file system works. However, the consensus is that most cards don't show issues until after the 8GB is filled which would heavily suggest that no matter how it's doing the file system it fills the 8GB first.

Got my Samsung card

Ordered a 2nd Samsung card and just got it.

Ran CrystalDiskMark to compare to the SanDisk card that I previously purchased. Same PC, same SD adapter.

From reading other posts I was expecting slower sequential results and faster random results. Not sure what to make of this, but maybe it will help someone else.

I'll go ahead and throw it in my phone and try it out.

Local salesperson suggestion

I am a bit hesitant to post this information as it may or may not be very useful.

Today I went into an AT&T store, asked for a manager and questioned him about the cards listed on the AT&T site as ‘official’ Samsung Focus accessories. I wanted to know if the cards listed are guaranteed as compatible. His answer was no, they are generic microsd cards that may or may not work. He told me not to buy the listed cards and that there would be certified cards soon and that these would probably be class 6 microsdhc. When pressed he said by the end of the month.

This came from a sale person at a local store so it may be worthless info. However I have been dealing with these people for years and they have provided correct predictions in the past. I can wait a month but not much longer...

Mark
[Focus General] FishFaceMcGee:
Well the Class 6 thing seems like BS with the recent trend of stuff being "faster" than Class 4 not working well.
[Focus General] arrrgh:
Well, looks like I wasn't quite as lucky as I hoped. My SDSDQ-032G-A11M card lasted 4 days with 18GB used. Today I found the phone stuck to the Samsung screen for the first time.

At least I have a Nokia phone as a backup so I can format it.

[Focus General] kawgirlval69:
finally found the breaking limit on my sandisk 16gb class 2... had been going good for a few weeks with 15gb... added a movie and put it over 16gb used and had a reset but no lost data..... so i added 1 more 1 gig movie... it reset 1 time with no lost data... plugged it i to charge and 5 min later it rebooted again to all wiped...

so seems anything up to 8gb on the card was ok but over it flops... im going to try a 16 samsung class 4 , a 16 sandisk class 4, and a 32 sandisk class 4... i will report back with those results...
[Focus General] sabesh:
I just ordered a Focus and should get it next week. I'm getting a bit nervous reading this thread, lol. A few newbie questions (yep, I've tried search):

- How does one soft-reset the focus? (I did find out how to hard reset).

- Should I format the MicroSD card in the Focus or on a PC before use in the Focus? (Kingston 16GB Class-4). Thanks!
[Focus General] OklaPony:
Soft reset is under settings>about. As far as I know the only way to format a card for the Focus is in the Focus. Some have suggested going through the format process twice to help ensure stability although that didn't work for my Lexar 16/4.
[Focus General] sabesh:
Oh, I thought that method was a hard-reset as per this thread? (Method 3).

http://xdaforums.com/showthread.php?t=839865

Thanks,

Sabesh.
[Focus General] OklaPony:
Yeah, it seems to act as one but other than punching a code in the keypad or holding the 3 buttons I don't know that there are any other ways to do any kind of reset.

Funny thing... when I was typing my first reply I first wrote "The soft reset (if you can call it that) is under settings..." but edited the parenthetical section out. Guess I should have left it in after all. :)

Out of curiosity why are you looking for a soft reset?
[Focus General] sabesh:
Folks who posted that they did a "soft reset" in this thread:

How exactly did you "soft reset"? Thanks.
[Focus General] sabesh:
Well, I want to test and see if my data remains intact after a "soft reset" as per the first post in this thread :)
[Focus General] FishFaceMcGee:
As far as I understand (and maybe I've always misunderstood), a "soft reset" is power-cycling the phone. Hold the power button until it says "Goodbye!", and then turn it back on. After the card actually has data on it, there is a chance that the phone will act as though it has no storage if the card is bad. Typically, you can soft-reset the phone again and it will see your data again, however this usually means the phone is going to fail completely soon if you keep the card in.
[Focus General] sabesh:
Thx very much!
[Focus General] FishFaceMcGee:
You're welcome. Just be aware that until you're using more than 8GB of storage, it's entirely possible/likely that you will not see any problems.
[Focus General] sabesh:
Yep, I've read this. I plan to test with about 18-20GB of data. Cheers.

[Focus General] mesonto:
Kingston 16GB Class 4 seems to still be working perfectly

When I ordered my Samsung Focus I immediately placed a Kingston 16GB Class 4 SDHC card into it. I have had the phone for over a month and it is still working flawlessly. No slowdowns, hiccups or reboots that I can tell. One thing I have noticed is that my available memory at 22.12GB is hard to fill up, I still have 15GB to go! Not that I am trying. ;)
[Focus General] RGBell:
Apparently the problems start up after a couple of days. Last night my phone rebooted while sitting in standby mode. Today it rebooted when I tried to run the Facebook app and it appeared to have lost all data. A reboot brought it all back. How can it work flawlessly for two days and then flake out? Sigh...
[Focus General] FishFaceMcGee:
Well, that's why you haven't had any problems yet. You're not over 8GB.
[Focus General] PaullikesWINMO:
Okay... made it to Futureshop just before they closed. I bought this Lexar Card. I can confirm it is a Class 4. I have done the hard reset and phone says:

Total Storage: 22.10GB

Available Storage: 20.97GB

Wooohoo ! I will now start syncing all my music and video which I know will use at least 17GB so the data should write over to the card. I will let everyone know how it goes. This is a steal of a deal if it works.
[Focus General] PaullikesWINMO:
Trouble out of the gate. I changed the volume settings, phone re-booted and now total storage reads 15.73MB and available storage reads 10.67MB :(

Tried hard boot as other have tried but it seems I get same reading. So this $25 card might be good, but not for this phone. Maybe back to the web to order the 32GB microSD I listed earlier.
[Focus General] RGBell:
I decided to try a soft reset (power cycle). to test the phone. It booted to the Windows Phone screen and sat with the "busy" dots for about 2 minutes and then the screen went blank. It would not respond to any button, including the power button. I had to remove the battery to get it back. It did the same thing again. While it was sitting on the Windows screen it would vibrate when I pushed the 3 soft buttons but did nothing. It eventually went blank and froze again. I just did a hard reset to get it back. What a bummer!
[Focus General] StriderNo9:
So far I have around 12 to 13 GBs filled up, with games music, videos, pictures and other apps. Phone works great. I have some issues with the screen but I dont think it has to do with the card, I just think the sensors on the Focus need an update.

Other than that, no lock ups, no restarts and when I first put my card in the phone I reformatted and reset the phone like 6 times, phone saw all my space every time.
[Focus General] PaullikesWINMO:

Not a bad deal considering it's CAD$ website. Slightly cheaper deals in the USA via Amazon.com but shipping costs were high to get it to me.

Let's hope this one works because the re-setting of the phone and re-syncing of music, photo's and all settings and email accounts is time consuming.

There isn't a model number on the back?
[Focus General] jeffgeno:
I can't believe people are still trying 32GB SanDisk cards after reading this thread. You may be one of the incredibly lucky ones who have it work out, but the odds are against it. I don't think I'd place a $100 microSD card on that bet.
[Focus General] Sebo1985:
@FishFaceMcGee: There is a model number on the back, but thats a card specific number. It isn't the production line number of the card like this: SDSDQ-032G-A11M

Am I wrong with that?

@jeffgeno: In this thread there is only one guy using a class 4 Sandisk Card, and that guy does claim it works for him, with data loaded on it. Worth a try, card can be sold via ebay with nearly no loss (perhaps I even make some money ;).
[Focus General] FishFaceMcGee:
I think you're right. My bad.
[Focus General] jeffgeno:
I used a SanDisk Class 4 card myself. It's right there toward the start of the thread and it failed just like the rest of them. Worked fine for a couple days and then started rebooting.

Keep in mind you need a Symbian phone around to unlock it after you pull it from the Focus if you're putting it on eBay. It'll be worthless to the buyer otherwise.
[Focus General] Sebo1985:
I have a N97 right next to me ;)
[Focus General] OklaPony:
Sorry I didn't get to respond to this thread a little more often yesterday as I may have been able to save you some trouble. I had just posted about this card a couple of days ago, it failed for me even though I wasn't anywhere near going over the 8 gig mark.
[Focus General] sabesh:
So, I think it's safe to say that no one has had full compatibility with 32GB cards!
[Focus General] PaullikesWINMO:
Yes it's sounds like a hit and miss. for sure. I think the SANDisk is the best bet although not guarenteed.

Soon as I receive it and can install it, I will post my results. Crossing fingers it will work, otherwise I will wait for certified cards to be manufactuered and shipping to retailers. This is taking a lot of time to re-sync phone (music and pictures) and all the personalized settings to set up again.

Shoulda Figured

Went a couple weeks ago and got the buy one get one deal on the focus from ATT, then found this thread right as dad was clicking the buy it now button on Ebay on a pair of 32gb Kingston Class 6 MicroSDHC cards, Woulda been a great idea...

A week later they showed up, popped em in, did the Volume Down + Power + Camera hard reset, and Voila they show around 37gb of available storage... even after a Soft Reset, still showed tons of storage, Got excited...

Finally got the PC running again after a few days of using the cards to download apps and whatnot and put around 12-15 gb of Music/Sealab Videos/AOTS Podcasts and went to go see if anything worked and got errors on anything i tried to play or open, Did a soft reset and poof back to the "Getting started screen" that shows when you hard reset...

Dont know if I should attempt anything else but as far as I can tell:

Not Working: Kingston 32GB Class 6

Serial:SDC4/32GB

N0043-012/A00LF

Back: RA02013883SK

Anything else I can try would be greatly appreciated but guessing its another one to hit the bottom of the list...

Dads still hasnt added more than 8gb to his so its still working nicely but guessing he will run into the same wall I did...
[Focus General] Soundtweaker:
I would hold on to those 32gb cards. They might just start working correctly after this January update arrives.

"Serial:SDC4/32GB" -- that is a Class 4 microSDHC, not class 6. http://www.kingston.com/flash/sdhc_micro.asp

Both of those will show you that the SDC4/32 is a Class 4 product. :)

If you were to go back through this thread you will see that I had a similar experience with a slightly different "Class 4" 32GB Kingston memory card, unfortunately.
[Focus General] BJWall:
My 2 cents...

Been using an 8 gig Kingston class 4 for about a week now and no issues. All is good so far and I have it (and have had it from the start) pretty full with games, music and movies. All running fine. Not sure if thus was a fluke since the first post says this card has issues.
