Actually that would be really helpful. I'll also look into the ports. Maybe, since this problem seems to be caused by a number of things, it will be a number of small changes that produces a workaround. Thanks!
[Samsung Galaxy Tab Plus] Zadeis:
OK I'm back with 2 pics of my wireless settings on my router. I blotted out obvious stuff like the SSID and password for my sake.

And in advanced Settings

For an entire 5 days (before my Tablet crapped out and I had to send to Samsung and still waiting on that) these were/are my router settings and I did not have an SOD issue. Mind you these were also the same settings while I was still having SOD issues. If you go here you can see what I did. I think my problem was connected to my SD card and not the wireless.While I was having the SODs I used Auto Airplane mode and had less frequent (maybe once a day down from 2 or 3) SODs.
[Samsung Galaxy Tab Plus] jonsteckelberg:
sod

I seem to have stopped my sod problem by installing softlocker free. It does seem to drain the battery slightly faster but I will trade that for no sod's.
[Samsung Galaxy Tab Plus] M7amad90:
Almost the same ( which is wierd :confused: )
[Samsung Galaxy Tab Plus] rkmj:
I don't know if you've tried Auto Airplane Mode by DON, but it's in the market for free and doesn't drain the battery, in fact, helps prolong it. If you have tried it and it didn't work, disregard this message.
[Samsung Galaxy Tab Plus] GTOJim:
Replaced my Tab last Saturday (Jan 28th) so far not one SOD. Disabled Auto Airplane Mode, using a Sandisk class 4 card.

The only difference, I switched to using the 5GB band on my dual band router and haven't rooted it yet.

Looks like my first tab was defective.

New firmware and SOD?

Just wondering if the latest firmware released by Samsung fixed the SOD issue (probably they paid attention to Gary) I just installed it, I will run a few tests and come back to post the results.
[Samsung Galaxy Tab Plus] Zadeis:
Are you running Gary's kernal also? Just curious if there are any issues with it.
[Samsung Galaxy Tab Plus] garyd9:
There are changes in the wifi driver (and sdio code from the looks of it) in the latest (LA3) firmware. This may resolve SOD issues (but if you install the firmware update, DO NOT install my kernel until further notice.)
[Samsung Galaxy Tab Plus] rkmj:
I'm going to be running this update tonight and testing extensively. I'll post again with my results. Here's hoping this puts an end to the miserable old SOD
[Samsung Galaxy Tab Plus] orb360:
So I'm guessing since people have stopped posting that the new tab update resolves this?
[Samsung Galaxy Tab Plus] rkmj:
Since I applied the update to my tablet, I haven't had a single SOD (knock on wood.) It seems that other people aren't experiencing this as of this moment. If in another week I haven't had any SOD's, I'll feel comfortable in saying that this update fixed it for me.
[Samsung Galaxy Tab Plus] maff1989:
POSSIBLE SOD fix for GT-P6210

Ive had experience with SOD's running Android from the SD card on the HD2. The cause for those SOD's was due to the class of the SD card. Seeing as how our tablet comes with an "internal" SD card, thats kinda hard to fix, right?

The possible fix comes in regarding the read_ahead_kb setting for the SD card. Ive installedn SD Booster, which is free from the market, and found out that the read_ahead setting is set to 128 by default. Tinkering with those settings will reveal that 1024-2048 are superior settings.

This is the procedure:

1. Install gary9d's custom kernel (wipe /cache and dalvik-cache!!)

2. After rebooting, open up a root explorer and navigate to /system/etc/init.d. if the directory doesnt exist, create it.

3. Create a file named "1sdcard_tweak" w/o the quotes and modify the permissions so that way user has r/w/e. Give group the same settings, and give others all permissions except write.

4. Open the file and paste the following in there, then save and reboot:

#!/system/bin/sh

echo 1024 > /sys/devices/virtual/bdi/179:0/read_ahead_kb

Not only could this fix SOD's, but I've noticed much, much smoother performance changing this setting. I have mine set to 1024. I am also on this firmware.

Hope this helps!!
[Samsung Galaxy Tab Plus] lrs421:
Well, 6 weeks into ownership I just had my first SOD.

- US Wifi 6210

- Not rooted

- Running the latest firmware from Samsung

- 32GB Class 4 Transcend Micro SD

- Router is from Verizon Fios, 802.11G. Actiontek I bekieve

- No auto airplane software
[Samsung Galaxy Tab Plus] garyd9:
"latest firmware" can mean different things to different people. Can you please be specific as to which firmware version? Can you also describe the circumstances under which you had the SOD? Was the device unattended for a while? Was it plugged into a charger? Was wifi on? What are your wifi sleep settings? Do you have anything going on with your tablet that would cause it to use the wireless while its unattended (such as email, IM/skype, etc?) How about something that might use the sd card?

Thanks

Gary
[Samsung Galaxy Tab Plus] lrs421:
Sure, my build number is LA3. I got a small 9mb or so update from Kies the other day. The update that I believe someone said had updated wifi drivers and a kernel change.

My battery was about 28% (not plugged in) and wifi was on. I was just browsing the web. I put the tablet down for about 10 minutes but when I came back it didn't response to the power button. I tried several times. I then held down the power button for about 5 seconds and it powered up.
[Samsung Galaxy Tab Plus] rkmj:
I'm still testing settings and configurations, but I am experiencing SOD's again. I'm not using Auto Airplane Mode yet because I want to gather more information on my specific SODs, but for me, UELA3 is still SOD-prone.
[Samsung Galaxy Tab Plus] lrs421:
The weird thing is I didn't experience one until I upgraded to LA3.
[Samsung Galaxy Tab Plus] rkmj:
That's awful. I'm slightly disappointed that I am still experiencing it, although it's much more rare for me than others are reporting, but if I hadn't experienced one and started having them, I would be much more frustrated. I may be able to solve mine with a few changes to my wifi and power save settings (I have a hunch.) I'll post here as soon as I have more info from my tests.
[Samsung Galaxy Tab Plus] lrs421:
Cool, let us know what you find.
[Samsung Galaxy Tab Plus] koolto:
Ok, I can sadly report that the latest firmware (LA3) does not fix the SOD issues in our little friend.

I disabled Auto Airplane Mode (which fixed the isssue for me) and tested using the following two configurations:

- WiFi setting "Always On", tablet went on standby mode, tried to use it after about 10 minutes and it was dead, had to press the On button for 15 seconds to bring it back to life.

- WiFi setting "Off when screen off (or something like that)", tablet went on standby mode, left it like that overnight, the following day the tablet not only was dead but the battery was completely drained (was 56%).

So now I'm back to Auto Airplane Mode, it's sad to see that Samsung has not responded to the complaints of users from all over the world.

I did not notice any improvements with this firmware but that's another topic.
[Samsung Galaxy Tab Plus] lrs421:
Or even worse, this update was their response and it's still not fixed.

As a side, I've been trying to duplicate the SOD I experienced and have not been able to.

I've had a couple on my Galaxy Nexus using 4G as well so perhaps Samsung isn't doing something right with their kernels.
[Samsung Galaxy Tab Plus] maff1989:
:D

Ok.. I believe I may have figured it out. PEOPLE PLEASE TEST THIS. It's such a simple edit!

If you haven't done so, root your device. Install Superuser and Root Explorer (or a similar r/w file manager). Open up your build.prop and find the line wlan.driver.apmode "unloaded" and change it to wlan.driver.apmode=unloaded.

apmode, I believe, stands for "Air Plane Mode", which would explain why people were seeing positive results using Auto Air Plane or whatever the program is called.

I had my first two random shutdowns today. Changed this line of code, left Wi-Fi on in standby for a couple hours, and haven't had a shutdown yet. :D

EDIT: I can almost guarantee the new firmware (LA3) doesn't have this line of code fixed.

Also, you can remove that keyguard.no_require_sim=yes line of code because keyguard.no_require_sim=true already exists and is the correct code.

UPDATE: After letting the tablet sit in standby with Wi-Fi on (default settings) all night long, woke up and tablet still had not shut down.
[Samsung Galaxy Tab Plus] Zadeis:
Well sadly after 4 whole days I didn't get an SOD (I got the newest recent firmware also) but today had 2 within an hour. I'm going to try the above post though and see what happens. I also haven't been using auto airplane mode.
[Samsung Galaxy Tab Plus] Zadeis:
Well I have been fine for the past ten hours still with no SODs and I'm not using any auto airplane mode either or using Garys kernel (mainly because he hasn't ported it to the new firmware). Maybe modifying that one line actually was causing some major issues. If that is the case I will be severely disappointed in Samsung.
[Samsung Galaxy Tab Plus] garyd9:
"apmode" refers to the "portable hotspot" feature found on many android phones. It doesn't apply to the 6210, as it doesn't have it's own internet connection to share.
[Samsung Galaxy Tab Plus] Zadeis:
Ah ok. Well strangely enough I'm not having SOD's since I did that... I had two in one hour and after the second SOD I tried that change and it seems to be fine (knowing my luck I'll have another SOD tomorrow)

I kinda wish Cyanogen mod worked on this that way we could see if it had issues on that too. But oh well.
[Samsung Galaxy Tab Plus] Boogydefarno:
In my experiance I don't get the SOD with my Tab whilst it is plugged into the wall socket on charge. I feel that the failure to start or "wake up" from standby occurs in that nano second when you press the power button. It is almost as though there is a link between a request for power from the button and the motherboard and the battery and sometimes that link isn't made,when the device is plugged in the " request" for a charge from the battery doesn't occur and the device "wakes up". Has anyone else made this connection?
[Samsung Galaxy Tab Plus] jmar8124:
i have solved SOD...i think haha

Hey guys,

Im Joe Marshall

I have been running my g tab+ at 1600MHz from day one and then i got the SOD issue a week in i changed the firmware to XXKL7 and i use it a lot with high definition games and movies i have had no issues what so every from the firmware change its great now. i am still running at 1600MHz. do you think it could be a firmware issue or a faulty batch? my tab was originally a Honk Kong tab and i have changed the firmware to the XXKL7 European version with Odin v1.85. if anything i use it more now than i did before. I am yet to experience any issues so my conclusion would be the hardware accelerator in the other firmwares are messed up their for messing with the change in velocity in the g-tab. problem potently solved

if this worked for you please press thanks button
[Samsung Galaxy Tab Plus] rkmj:
Surprisingly, right after switching to the new firmware, I had 2 SODs in 2 days, which was a lower rate than I was experiencing before the update. (They each happened when I was coming in from driving, (no wifi connection,) and going into an area with a known, remembered wifi network, (home or work.) Since then, though, I haven't had a single SOD. I don't know what's going on anymore, but I'm grateful that I'm not seeing them.
[Samsung Galaxy Tab Plus] Zadeis:
Well I will say I just got an SOD after a whole 8 days. So the problem still isn't completely gone but obviously much less frequent.
[Samsung Galaxy Tab Plus] rkum19:
I just purchased one on ebay yesterday. Decided to browse the "Galaxy tab 7 plus" forum to see what is the most popular topic for this device. Its sad to see that this is one of them :(. Has anyone found a fix yet? Seems like most people are experiecing the error with the latest firmware. Can anyone confirm what "jmar8124" recommends, changing the firmware to the XXKL7 European version with Odin v1.85 will fix the issue?

Is this a deal breaker for anyone?

Has any one RMA'd do to this issue?
[Samsung Galaxy Tab Plus] ikeny:
There hasn't been any new posts to this for a month now. Is the problem now fixed (e.g., with updated firmware)? or have we all given up on the issue?

I bought a new GTab+ from Bestbuy 2 days ago, and it experienced 2 rebooting on its own during standby this morning (first one while connected to AC, second one on battery).

I am still within the return period, and wondering about it.

[Update] P6210, stock rom, rooted, no setCPU installed, only modification made was editing the permission for writing ext SD.

(I wasn't sure about the supercharger script what was mentioned in earlier post; what is it anyway? was it applied automatically what rooting the the root.zip posted here?)
[Samsung Galaxy Tab Plus] Zadeis:
As far as I can tell some people are having it less and some still are frequently, some not at all. So no it hasn't been fixed but I think everyone for the most part is waiting for Ice Cream Sandwich to be released and hopefully that will alleviate the problem.

In terms of supercharger its a script that changes certain things which in turn causes devices to use less ram thus giving more performance and less redraws on the home screen, etc. I used to use it myself until I had to do a restore and I haven't done it yet... The normal experience has been fine for me as of the late and now I don't see why I did it in the first place...
[Samsung Galaxy Tab Plus] ikeny:
^^^ Thanks. I just want to add that I previously owned a Lenovo Ideapad A1, which is also a 7" tablet but running Gingerbread. It also suffered from random reboots during standby, and SOD. So the issue is not just with this Samsung GT+
[Samsung Galaxy Tab Plus] orb360:
I still get them a couple times a week... But I've given up on finding a fix.

Hopefully ICS will fix it.

If not, I'm just going to sell it.

Screw Samsung and their closed-source atheros wifi drivers.
[Samsung Galaxy Tab Plus] ikeny:
SOD or just reboots?
[Samsung Galaxy Tab Plus] orb360:
just sod's
[Samsung Galaxy Tab Plus] GTOJim:
Replaced my tab on Jan 28th and haven't had a single SOD since. Had two random reboots in that time, one a month, so seldom it's nothing to worry about.
[Samsung Galaxy Tab Plus] WangChung81:
I've been having this issue lately. I've been able to reproduce the issue faithfully, though I'm not sure how to fix it exactly. The issue is when the tablet is connected to a wifi spot and is "ripped" away. That is, when the tablet is connected and goes to standby, then I leave the house or turn off the tether to my phone. The tablet appears to not like this unexpected disconnect and freezes, causing me to soft reboot it.

I left my tablet on at home for days both plugged and unplugged, never locked up once when I went and checked on it. If I turn off the wifi on the tablet before leaving the area and/or manually disconnect from that access point the tablet doesn't freeze. If I have my tablet tethered to my phone and manually disconnect, good to go. But if I just turn off tethering on my phone, or I walk out of the house while it's still connected to my home wifi and the tablet is in standby, then it freezes.

So basically, the workaround is to manually disconnect it from whatever wifi access point you may be connected to before vacating the vicinity. Or, leave the wifi on the tablet off. While it may not be the solution for everyone, give it a try, would love to hear some feedback!
[Samsung Galaxy Tab Plus] CrisisCorE:
After experimenting around, at least for me sod was almost certainly a software-only issue. Try to flash cwm, then format every partition and reflash stock. This worked for me just fine.
[Samsung Galaxy Tab Plus] al160000:
I have a GT7+ 6210. My wife has one too. Both are updated to ICS. After a few days of having hers, she started experiencing SODs. Mine never had this issue for the first 6 weeks or so, and it has only happened once (the battery was completely dead after it). Hers does it without the battery even being dead, it just won't respond to the power button. The wifi is off on her tablet most of the time (and for sure most of the times that the SODs occur). She also doesn't have a microSD card in her tablet.

Is there any fix that anyone has found to consistently work for them?
[Samsung Galaxy Tab Plus] bebe.irene:

[Samsung Galaxy Tab Plus] Pempu:
Sorry for digging up a really old thread.

On my 6210 I am still having SOD just like the ones mentioned in this thread. Battery is depleting fast everytime SOD occurs.

If I manually turn wifi off before putting the tablet to sleep I can minimize the SOD's but sometimes they still come.

Any help out here? I am running CM11 now.
[Samsung Galaxy Tab Plus] charmartist:
You made a good move; Eventually I succumbed and did the same thing. Haven't had a SoD yet on the new one and this is after I updated the firmware.
[Samsung Galaxy Tab Plus] slyd0997:
SOD and random reboot

Have had my GT 7 plus for about a month. Getting about 1 sod per day and less frequent random reboots. I hate to do it but I guess I have to exchange...
[Samsung Galaxy Tab Plus] orb360:
I just got my first SoD last night... Had the device for 4 days so far.

If I get many more I think I may just call it quits and return it. IDK... I don't want to mess around with possibly repeatedly exchanging a device to _hopefully_ get one that works properly.
[Samsung Galaxy Tab Plus] amtrakcn:
I used to have random shutdown, after about it leaving it along for 2 days. Fixed after I did a factory reset.
[Samsung Galaxy Tab Plus] dtienes:
Still freezing

I just received my second Tab 7 Plus, and this one freezes randomly, as well. The device is more or less useless. I've tried disabling some apps, such as TuneSync, but with no luck. I've updated the firmware to the latest release and still no luck.

If anyone else has any ideas I'd be glad to hear them, otherwise, as much as I hate to do it, I'm sending this back permanently. There's really no good excuse for a $400 piece of kit to simply not work.
[Samsung Galaxy Tab Plus] ufa:
Did you factory reset it?
[Samsung Galaxy Tab Plus] diospada11:
it has been 8 hours since i bought my tab+ and still no SOD :))))))))))

Mine is P6210.
[Samsung Galaxy Tab Plus] gersen416:
SOD Fix?

Also have a GT+ with the SOD issue and after reading this thread here is what I did:

1) Upgraded firmware to latest version using Kies

2) Performed factory reset using the recovery console (power + up volume) NOT the one under Settings > Privacy > Factory Reset

3) Replaced default launcher with Go Launcher

4) Formatted the 4GB uSD card using Settings > Storage > Format SD

This last step appears to be important to allow Honeycomb on the GT+ to properly set rights for the SD card that I suspect plays into whatever process is getting stuck when the screen is off eventually leading to the SOD.

Other settings and points of interest are:

wifi off when screen off

No custom power savings

the only widget i use is ES Task Manager to kill restarters

I have not rooted or modified the unit in any way

I have not had an SOD in 10 days since averaging about 2 per day.

Battery life is solid and perhaps loses 2%/day in standby

Can't conclusively say this has fixed the SOD problem, but it looks promising.

I'd appreciate others taking the time to post details of their environment to help get some final resolution to this problem.

A quick review of some of the other forums on XDA indicates this affects other Honeycomb-based devices from Samsung, Acer and others leading me to believe its a bug in Honeycomb or some SW problem with apps most people are using.

I have no idea - saw it posted somewhere and it stuck. Know it shouldn't make a difference but for some reason it does. Perhaps a DEV can explain the difference. For now this black magic and fireplace chanting seems to keep the SOD demons at bay.
[Samsung Galaxy Tab Plus] slyd0997:
Sod fix?

I tried today. Did everything except using go launcher and had a Sod tonite. Why do you think which launcher matters?
[Samsung Galaxy Tab Plus] diospada11:
Go Launcher lags with our tab+ since it is not hardware accelerated and is not optimized for honeycomb.
[Samsung Galaxy Tab Plus] slyd0997:

And you think lag in go launcher helps prevent the sod? Why?
[Samsung Galaxy Tab Plus] naturefreak85:
I had the screen of death multiple times, through testing I found that turning off the lockscreen resolves the issue. I do have 6 dead pixels in my Tab so I'm contacting amazon for a swap, with the new one I'll see if the issue still exists.

This actually is my 2nd tab the 1st one had a sharp plastic edge that actually cut me, that one didn't have the shutdown, but did have random reboots when playing music. Should be interesting to see what Tab 3 brings.

From what I was experiencing SOD happened when connected to WiFi only and lockscreen was on. If I had my device in Airplane mode and Lockscreen was on, it wouldn't SOD. I thought it was related to Push Notifications in Programs, but that wasn't it. What I did notice is, when I turned off the lockscreen with the same usage, I noticed my Battery life increase drastically. I want from losing 10% in 30 minutes of reading Manga (Japanese Comics) on MangaWatcher to losing 3% in 30 minutes of reading Manga. Not sure what is causing it, but it's interesting to say the least.

EDIT: I take it back, just had my first SOD happen. Nearly 24 hours of perfect no issue use with the lockscreen off. Even 6 hours of sleep with no internet connection and WiFi on, (scanning, left in the trunk of my car) the SOD happened at my house when connected to my home WiFi Router. At this point I'm left thinking it has to be a software based issue relating to push notifications.
[Samsung Galaxy Tab Plus] orb360:
My sod rate has been going up over time... None for the first week but up to twice a day now :-(

Hopefully there will be a firmware fix from samsung...
