How have you reached the conclusion it is the driver?
The driver is cheap and easy to replace/repair yet Samsung have not addressed it. Replacing the driver would have been a real company credibility saver yet they haven't done it - why? Easy; because it is a hardware problem.
After leaving this issue for a while (a few month) I've now checked to see if somebody have a new idea - and it seems guys are going in circles.
I've managed to avoid the SOD just by not putting any SD card in the phone.
it seems there's some hardware bug on the SDIO bus (WIFI and SD are on the same bus) causing the software to hang. this is ofcourse a software bug also, since the software should just retry to read from the device or even reset the SDIO device - but as we can see, the software just goes into a deep sleep.
I guess different handsets have a slight different problem, and that the reason why some guys have a slight different behavior of the problem.
the conclusion is simple - hardware bug which enables a software bug.
I'm sure 100% that it can be solved by software, since the SDIO is an external bus which should not be able to kill the application processor.

Will test this out! Thanks!
However, I don't think that it is an acceptable solution. Samsung shouldn't make a phone that cannot handle an SD card... My internal memory is almost full already. My 4 year old Blackberry was better built than this phone...
But if that helps me getting rid of the annoying issue, then I think that's the way to go.
After using the phone without SD card for a couple of month, lately I needed the SD card a bit more (can't install anything without the card, you need it as temp storage ..)
I looked a bit more, and found that there is a new firmware for the Samsung ACE - XWKPT (release date aug 11). this release is 2.3.3 and not 2.3.4 as previous one - a bit strange, but kernel version on both is 2.6.35.7.
Any way, with this release (which has different AR6000/wifi driver) I have the phone running now for two days without any SOD - previous record was 20 minutes. (WIFI + SD !!!)
firmware is from www.SamFirmware.com
I've also installed the 2.3.4 RTL fix (with deodex) and it also works fine together.
Now lets see if this solution is final or just better statistics ...

Claiming a solution is somewhat pre-mature after 2 days!
I have no confidence this will resolve it for all.
claiming for a fix after two days is possible, since i have a wifi scenario here causing SOD after 5-15 minutes.
now it's already 3 days - no SOD at all.
regarding all those who claim it doesn't solve the problem (nor the without SD workaround) - you have another problem causing SOD on your device.
So far, now a bit over 222 hours with no sleep of death or other issues.
Sir, I wanna know what did you do with your Ace. I have been experiencing this a lot recently. I believe though that this is not a hardware issue. My officemate had an Xperia 8 on Gingerbread and rarely uses his wifi. Even before I had my Ace, he has been experiencing this SOD. I had my Wifi settings to never turn off even if the screen is off. I experience this even when my wifi is turned off and even with no active applications. My officemate told me, it maybe because of a memory dump or something. I dunno. I'm still not so sure. I hope there will be a way to prevent this from happening again.
The 2.3.3 update from Kies (CPW update) has solved my wifi SOD issue, however, it has brough many more....ie:
Phone is very laggy now
When on a call and I move the phone from my ear, the screen does not light up to allow me to end the call. The new firmware has made the motion sensor very laggy also!
The biggest problem is not being able to send MMS messages at all and can't send SMS messages unless either data packet service is turned off, wifi is on or 2G only is enabled.
Wish I hadn't updated.
Actually, I wish I never got the Ace. They should rename it the Samsung Galaxy Arse.
Well, we got a replacement SGA and kept it on default settings. It has had a random shutdown once since than. But not a sleep of death type thing. Pressing the power button revived it. No need to remove the battery. I do make it a point to reboot every 10-15 days. Still not on GB though.
Thanks, Sir. I've read your blog about it. However, I'm still not yet fully convinced that it is a hardware problem. Just like what I've said, my friend had the same issue and symptom on his Xperia just before I bought my Ace. I dunno what he did to his phone afterward and said that he's no longer experiencing SOD after upgrading to Gingerbread. I'm gonna wait for updates though.
The latest sw update to 2.3.3 via kies has completely solved the issue for me. Phone is up for 6 days now without any problems. So it turned out to be SW issue after all
Just to let you all know the cure for this. I had to return my wife's phone to Samsung Malaysia as it had the same problem of turning off.
They checked the phone over and upgraded the firmware to Gingerbread 2.3.4 it's been back a week and it hasn't turned off yet. It's faster and has new layout.
Their comment was that it is purely a firmware fault.

I ended up giving up, and have now got a Samsung Galaxy Ace. Interesting about the Gingerbread fix. Will ask someone a bit more up with the play than I am about how I might upgrade it.
I just upgraded mine to official 2.3.4 and I think I'm loving the slight visual changes. There were some missing options like the message skin option and turning on/off USB debugging. I don't know if USB debugging is already turned on for this.
I have started facing the SOD after i have upgraded to Gingerbread, a few months back. Lately is very painful as it won't last even a few hours unless is on power.
I probably need a reset or format, but how can i get everything back on. I am looking for the simpliest way other than rooting, etc cause then i would need a whole weekend on this.
Currently i have 2.3.3 on, so either want to go back to the previous version i was, if that is possible, reinstall the firmware (2.3.3) or ideally go to 2.3.4 which is not available for me yet(how come?)
I appreciate any help you can provide me.
The only thing which prevents me from getting SODs is by using the SD card which was supplied with the phone, if I use any other card my phone still has SODs.
Exactly the same for me. Even bought a 8gb samsung sd card but still SOD'd, but more so! Stoopid phone... but I still love it; much much better than my previous one, despite it's obvious, um, personality problems...
I have tried it myself for the past two days and I haven't had any problems, BUT I have had my WiFi turned off completely unless I need it, because my dad reread the forum and said that the problem is not in the WiFi going into sleep mode, but the WiFi itself. Guess I misunderstood. Turning WiFi completely off has worked for me for the past couple of days, perhaps you could try that? I really hope Samsung notices and fixes it soon.
I have the same problem, but Im pretty sure it has nothing to do with wifi. It turns off itself no matter if I have wifi on or off. Ive heard there could be problem with the battery contact, cause my doesnt start up until I take the battery out
Best way to fix SOD, is flashing your ROM. Me and my friend both had SOD on Froyo, Gingerbread(bbth official). After we flashed to KPT, it fixed our problem. I've been using my phone for more then a month and it's really SOD free. News - www.SamFirmware.com -> This is the only way to fix it if you want to use your wifi always switched on. Use odin, and check two or three guide for flashing. I'm pretty sure it will solve your problem I hope I could help you guys
And, believe it or not, it's Gingerbread 2.3.5 update, officially through Kies (Europe)
I hope this would not reintroduce SOD, since I was SOD-free since 2.3.3 KPO.
First couple of things I noticed:
1. Much less screen lag on wake-up
2. when SD is unmounted, generic android icons are not shown for apps that are on SD card - nothing is shown at that place until SD is reinserted.
3. Much faster SD card mounting.
Still SOD with flashing various versions of gingerbread
I still get SODs even though i have reset, erased all, format, flashed, and many more.
I don't get thought. Since im holding a plain stock looking rom at the moment and still get randomely shut offs.
Could it be really a hardware issue then. I have always doubt it, but that is my only option now, to just go to the store and hopefully they will give me a new one.
Unless is the battery.
that's all.
Btw, i don't know how much it matters but my device is the Galaxy Tab.
A few time ago I said that SOD was solved for me but... it wasn't. For the past 3 weeks I've been experiencing SOD again.
My rom version is 2.3.3 and Kies "says" that's the last firmware.
Just upgraded to 2.3.5. Up until now the only problem is that it's not rooted.
Well but the upgrade was done 10 minutes ago... lol
I really hope that SOD is solved.
My Galaxy Ace randomly shuts down after i have upgraded to gingerbread in Samsung Kies... Before, i had froyo, never had a problem. now, it freezes every few hours and it has nothing to do with wifi. it does it regardless of whether i have it on or off. and its not hardware issue neither, unless upgrading process fried few components. never had a problem before i upgraded.
Hmmmmm.... I've owned a secondhand Galaxy Ace now for a month. Bought from the bay of fleas. Great price, took a chance and have been delighted with it for a month now. No issues whatsoever AND starting to like it much better than my Iphone 3GS. Until 3 days ago that is!!! Yep, you guessed it - SOD syndrome! Let it happen 3 times in a day and then decided to google the issue and found this thread. 7 pages long and I started to read through. I got to around page 5 and started thinking "what's changed on mine over the last 3 days" and remembered loading Myphone explorer (which I have changed one or 2 settings on relating to wifi behaviour) but also fitted an SD card for the first time. I started to think - "I bet it's the SD card" and then stumbled across the poster's link to the possibility that it's the sd card! Well, that's that then eh? So, today it happened again after I left the comfort of my home wifi connection. So I formatted the sd card using the phone and crossed my fingers. Ten minutes later SOD. Then I removed the sd card and so far so good. I'm no phone techie but my money is definitely on the link between wifi AND sd card. All we need now is a proper cure.
I absolutely hate it when a manufacturer makes that statement "this is not a known issue, yours is the first record of this we have received". Feckin' liars! Last time this happened to me was Renault denying there was an issue with Aircon on Meganes AND clutch pedals on Trafic vans. Well Samsung - go to the corner of the room and hang your head in shame!!!! Even if its a common droid issue and not Samsung don't lie through your back teeth guys!
my phone used to turn off after every couple of hours. i upgraded it to the android version 2.3.6 and the frequency of SOD increased to every 5 minutes ( and that is saying something).
i was just about to give it to the service centre but thought of diagnosing the problem online and i landed on this forum.
after reading all the suggestions, here is what i did.
1) Settings-> Wireless and networks-> Wi-Fi settings( you can press the menu button to go to advanced settings)>.Wi-Fi sleep policy>turn it to never.
2) i formatted my SD card ( factory format and not a quick format)
3) i started turning off my wifi whenever i was not in range ( my wifi is still always on whenever i am in range).
i have no idea which of the 3 worked or whether its a combination of all the 3 but its 4 days now and no SOD...and that's a records
Over a year my galaxy S i9000 was running OK. Until recently, when it gave up on me all by a sudden. After switching it on again I found my battery was doing about 80%. That surprised me a bit so I came here to read about other users experiences.
I detected multiple issues in this thread are mentioned.
1) Battery dies very fast.
2) Sleep of Death - Phone is in use and freezes. This leads to resetting or shutting down after some time.
3) Sudden death - Phone suddenly shutting down with still plenty of battery power left.
Three different problems with all their own solution. I'll try to get some things straight here. Just start reasoning out possibilities to solve the problem with my phone. Maybe It's of any use for all you out there as well. I would appreciate it if any tech whizz could add more knowledge to this.
1) BATTERY DIES FAST. If the battery dies quickly there could be multiple causes
a) High power consumption due to software issues (either android or apps)
b) Battery life isn't endless. Maybe it's had it's best time
c) Some hardware defect (short circuit) causing high power drainage
2) SLEEP OF DEATH. Sounds like a software issue to me. Probably memory is getting clogged up, which in the end leads to a crash. This memory clogging could be caused by bad programming behaviour from newbie programmers (memory leakage) and not properly taken care of by the android system. New firmware could maybe solve this.
When I just had my phone I had this problem, but after some firmware upgrades it seems to be solved.
3) Sudden death... My pain in the buttocks at the moment. First I thought of some kind of software issue. I did a 'Reset to factory settings' to wipe out everything. This didn't solve the problem. First thought was flashing the phone memory (that's why I landed on this forum). But reading through these threads I noticed that it doesn't seem to help. I read something about SD cards being part of the problem, so I took of the cover to inspect the interior of my phone and to check it's inner integrity. Apart from some dust there wasn't anything that... Wait a minute... Hmmm.... The battery is wiggling in it's housing. It doesn't stay on it's place the way I would like it to be. It reminded me of my previous phone, the Nokia N73. It had the same crappy mechanical problem...
I took a piece of paper in the same size as the battery. Folding it's edge over the bottom of the battery a few times and jam the whole package back in to the phone. Now the battery stay nicely in it's place, pushed upward against the copper connector pins.
Samsung GT-I9000 turns off sometimes without any reason, especially when I am using facebook, twitter, internet etc. and it won't turn on until I remove the battery and put it back also it turned off with old firmware versions as well.
I find that mobile turning off issue exactly when my battery level is below 25%
Mobile batter isn't genuine one but replacement even I had same problem when I had original battery.
Maybe is something wrong with the charger,battery, firmware what should I do ?

Hi all, it's been a while...
I recently updated my S5830 to XXKPT (2.3.6) via KIES, and guess what:
SOD is back!
Again, as before, using Auto WiFi toggle app is helping, but still... isn't it just odd that once solved issue is back again in newer version of firmware update?

Cheers.
Have you turned the wifi sleep policy to 'never'?
I use custom roms, and i don't get SOD there, maybe you should move to custom roms, they are much better.

Hi, I did turn on the 'never' sleep policy, as before upgrade. Still SOD-ing...
As for the custom ROM - what do you recommend?
I tried to install one with ROM Manager app, and bricked my Ace so thoroughly that I had to send it to repair shop, so I have some doubts about that...

You must have installed the official CyanogenMod(CM7.2), that comes preinstalled with ROM Manager, and its a very popular ACE killer
I am sure you tried to flash recovery from that and bricked your phone
Well there are several roms to choose from, it all depends on your requirements.
Look over at xda and flash whichever you like.
I'd personally recommend CM roms, i always go for CM roms, but your requirements might differ.
