Sod

I found the same thing - sod increased over time. Mine started after I had for about two weeks. Get about 1 sod per day. I also have some locking up.
[Samsung Galaxy Tab Plus] knowsnophones:
To those who bought the 7.0 Plus in the philippines capable of making calls and sms, have you experienced the SOD?
[Samsung Galaxy Tab Plus] naturefreak85:
I can't speak on the topic of the Philippines version but the T-Mobile version also has the SOD. The fact is, everyone needs to contact Samsung Support about this, send them the link to this forum thread and any others you may find on this topic. The more people that complain to Samsung about the issue, the faster it will get fixed.

Sod contact sprint

I tried to contact samsung on their website. Could not find a way to select GT7+ as a model to request support on. Has anyone succeeded in bringing this issue to samsung attending on the samsung website?
[Samsung Galaxy Tab Plus] garyd9:
First, I should mention that I haven't had the SOD issue on my P6210 since I first turned it on. I've had it since the first day that amazon.com started shipping them (which was a week or so before the official release.) My device is attached to an exchange server getting push notifications for email/contacts/etc. It's rooted, and I've gone at times with wifi on all the time, and wifi set up as "always when plugged in."

However, I'm curious about this problem and I see a lot of chaos with people trying to figure this out. In order to try and find a pattern to help, please answer the following questions

if you are having the problem

:

1. Which model are you using? (T869, P6200, P6200L, or P6210)

2. Are you using a microSD card in your device? If yes, what capacity/brand?

3. Are you rooted?

4. If rooted, are you using SetCPU (or any other mechanism to modify the CPU clock speeds and/or voltages?) (if not rooted, answer 'n/a')

5. If rooted, are you using any other program or modification on a regular basis (or when the SOD occurs) that modifies how the device normally runs? If so, what? (examples: tracker, mods to wifi for adhoc pairing, adfree, etc)

6. When the SOD occurs, can you use adb to communicate to the device? (adb devices, adb shell, adb reboot) (if you don't have adb, answer 'n/a')

7. During the time the SOD occurred, are you connected to wifi? (if it occurs for you both when connected and when NOT connected, answer 'both')

8. What is your favorite beer? Have you ever shared any of that beer (or any other liquid) with your device?

9. When the SOD occurs, is the bluetooth radio connected to another device? (if the BT radio is turned off, answer 'n/a')

....

Thanks and take care

Gary

1. Which model are you using? (T869, P6200, P6200L, or P6210)

P6210, 16GB originally, just got the 32GB haven't had a chance to test it and won't until I get my Zagg Skin in.

2. Are you using a microSD card in your device? If yes, what capacity/brand?

Yes, 32GB Sandisk Class 4

3. Are you rooted?

Nope

Haven't had a chance to try, each time it's happened I've not been near a computer but plugging it into the wall refuses to wake up the screen.

7. During the time the SOD occurred, are you connected to wifi? (if it occurs for you both when connected and when NOT connected, answer 'both')

Yes

8. What is your favorite beer? Have you ever shared any of that beer (or any other liquid) with your device?

Allagash White, and No

9. When the SOD occurs, is the bluetooth radio connected to another device? (if the BT radio is turned off, answer 'n/a')

n/a

On a separate note, I actually gained a 2 day reprieve from the SOD by turning off the lockscreen completely. I've noticed that they do happen when push notifications that would hit my phone and tablet arrive on the tablet. I'll hear my tablet go off, and then suddenly not when I'm getting messaged through FB messenger. It's as if the crash is happening through Networked Push notifications and crashing.

SOD's seem to have increased in frequency over time since I acquired the device. None the first week. 2-3 the second week. 1-2 a day now.
[Samsung Galaxy Tab Plus] diospada11:
nope. it has been nearly 2 weeks since i got my tab+ and i never experience any SOD.
[Samsung Galaxy Tab Plus] slyd0997:
P6210, not rooted, always connected to wifi, not plugged in, 16g San Disk, gave beer up 310 days ago but who's counting.

Also have random freezing while on wifi.

SODs and freezing started after I had about two weeks.
[Samsung Galaxy Tab Plus] naturefreak85:
Yea, I never did get the SOD when plugged into power, and depending on how long the device has been in SOD I notice a huge battery drain.
[Samsung Galaxy Tab Plus] garyd9:
For someone that has the SOD consistantly, please try to unmount and pull out your microSD card (when the tablet is working normally) and see if the SOD happens when the microSD slot is empty.

I'd also really help if someone could see if the tablet responds to adb when this happens to them. If so, some diagnostics could be run on the tablet while the SOD was taking place.
[Samsung Galaxy Tab Plus] mgymnop:
I had two Tab 7 Plus and both had the SOD without an SD card mounted.
[Samsung Galaxy Tab Plus] naturefreak85:
As soon as my new Tab (32GB) SOD's I'll be sure to try to run ADB on it, even if I have to install ADB on the GF's computer (she very well may kill me for messing with her computer, but I will in the name of science)
[Samsung Galaxy Tab Plus] garyd9:
For those without adb, when it SOD's, if you plug it into your computer, will KIES detect it?
[Samsung Galaxy Tab Plus] gersen416:
Thanks Gary - here are my tab specifics

7. Just with wifi on

8. no beer or bodily fluids have been in contact with my GT7+

9. BT disabled.

Lock screen always disabled.

Using Go Launcher as a replacement launcher

To my original post on fixing this problem, I had one SOD after that and have done the following:

Added Advanced Task Manager and set it to agressively kill background tasks when screen off

Added Auto Airplane Mode and changed Wifi sleep policy to "never when plugged in" or "never"

My thought process here is that a background task starts while the unit is in sleep mode with the screen off that gets locked and continues to drain the battery and prevents the GT7+ from coming out of sleep mode. I had my last SOD 5 days ago and not had one since.
[Samsung Galaxy Tab Plus] naturefreak85:
One person over at Androidcentral had said that his didn't SOD but when his unit was in sleep, it would crash using the SocialHub. The question is, would freezing that cause the SOD's to cease? Once my device SOD's I'll be testing this theory.

I'm also curious has anyone enabled the Samsung Dive software?
[Samsung Galaxy Tab Plus] StingerDog:
Thanks for posting this. Been having frequent SODs recently and have been lurking this thread looking for a resolution.

Usually have my tablet at home where its always connected to wifi (sleep policy set to "never"). Decided to take it to work yesterday where theres no wifi and didnt have a single SOD for over eight hours (but did have two random reboots).

Shortly after getting home from work I tap the power button just to make sure it wakes and is connected to my home wifi, I turn off the screen and set it down for a couple of minutes. When I pick it up and tap power I get a SOD. Hadn't been connected to wifi for more than five minutes and it SODs.

Suspecting a wifi issue I tried changing the sleep policy in the tablet's wifi setting from "never" to "when screen turns off" then turned off the screen and back on to make sure the wifi was sleeping as its supposed to.

Guess what? Wifi never disconnected. It stays on regardless of what policy I set. Only way to turn it off is manually. It was at that point I tried the suggestion above and installed Auto Airplane Mode and sure enough that puts the wifi to sleep when the screen turns off.

I spent the next several hours monitoring the tablet and turning the screen on from time to time to make sure it would wake. Each time I tapped the power it woke up and wifi turned on and connected as it should.

It's too early to say the SODs are gone so I will continue to monitor this and post back with results.

@garyd9:

Thanks for the work you're putting into this. I was thinking of setting catlog to record and hope for a SOD to occur so we can see what processes are going on when it happens. Do you think that would be helpful?

Shutdown Resolution Attempts

I've had the SOD consistently across two devices; in some cases I can't go more than 5 minutes before I get another freeze. It's wildly inconsistent; the device can go for a day with a single SOD, and then be practically useless for another day.

1. Which model are you using? <P6210MA>

2. Are you using a microSD card in your device? If yes, what capacity/brand? <Yes, from PNY. I used both an 8GB and a 16G>

3. Are you rooted? <Yes>

4. If rooted, are you using SetCPU (or any other mechanism to modify the CPU clock speeds and/or voltages?) (if not rooted, answer 'n/a') <Yes. I have the 'Scaling on demand' set to 800 - 1200, and the 'Screen Off' profile set to 800-1200, ondemand, priority 50>

5. If rooted, are you using any other program or modification on a regular basis (or when the SOD occurs) that modifies how the device normally runs? If so, what? (examples: tracker, mods to wifi for adhoc pairing, adfree, etc) <No>

6. When the SOD occurs, can you use adb to communicate to the device? (adb devices, adb shell, adb reboot) (if you don't have adb, answer 'n/a') <N/A>

7. During the time the SOD occurred, are you connected to wifi? (if it occurs for you both when connected and when NOT connected, answer 'both') <Yes>

8. What is your favorite beer? Have you ever shared any of that beer (or any other liquid) with your device? <I like Sam Adams, but not on my electronics.>

9. When the SOD occurs, is the bluetooth radio connected to another device? (if the BT radio is turned off, answer 'n/a') <No>

Last night I removed the SD card and installed an Advanced Task Manager that is killing almost everything on Screen Off. I have not had an SOD since doing this (I've had one with everything else I tried.) I'm going to go for another day without the SD card, then put it back in; I will report back.

Thanks to everyone for their feedback on this.
[Samsung Galaxy Tab Plus] clubtech:
I had two wifi 7+ tabs and i had SODs in both.

I then got the international version with 3G running the exact same configuration and not a single SOD since.

I also think the SODs I was seeing was related to the wifi as it tended to crash from time to time.
[Samsung Galaxy Tab Plus] gersen416:
Good to hear Stingerdog. Others with the SOD problem, please try adding both of the following free utiltities from the market and advise if it fixes your SOD problem. I remain SOD free without rooting.

1) Advanced Tasks Manager - Set to agressively kill background tasks when screen off

2) Auto Airplane Mode - set to restart

Having AA mode handle the wifi on/off policy rather than the stock ROM does appear to have a large positive effect on SOD's and stability.

If you do reboot the GT7+ please check that AA mode and Advanced task manager are running as background tasks. Although I set AA mode to restart at boot, it does not for some reason.

Also like the idea of cataloging the background tasks on a GT7+ that SOD's regularly as a way of determining the offending background process that could be eliminating in either a custom or stock ROM. Has anyone been able to get ADB to connect after a SOD?

Cheers and Happy New Year to all.
[Samsung Galaxy Tab Plus] garyd9:
I wouldn't be surprised if it's the ethernet. Of course, samsung neglected to release the ethernet (ar6000) driver source, so I'm having a fun time tracking that down...
[Samsung Galaxy Tab Plus] StingerDog:
Haven't had a SOD yet since installing auto airplane mode. Tablet has been on all day and wifi is sleeping as it should with the screen off.

As a side benefit I notice the battery is not having crazy drain down when sleeping for a while. Will continue to report what happens.
[Samsung Galaxy Tab Plus] naturefreak85:
I actually haven't had a single SOD yet with my new device, but I also haven't connected ANY samsung apps at all. Didn't log into Samsung Dive, Didn't log into anything on SNS, nothing. I was at the GF's house all day yesterday and left my tab down, over XMas it SOD'd 6 times until I turned off the lock screen (on the first device) and with the newest one, no SOD at all over the course of 9 hours left alone. It might be a combination of SNS and WiFi not sleeping properly
[Samsung Galaxy Tab Plus] StingerDog:
Interesting. My wife also has the GT7+ (bought them the same day) and hers hasn't had any SODs that she can think of.

I also turned off the lock screen on both tablets last week but unfortunately mine was still SODding. So far the only thing that has stopped the SODs is the auto airplane mode shutting down the wifi during sleep.
[Samsung Galaxy Tab Plus] LBJM:
I had the SOD problem until i unchecked a setting under settings--->screen called "auto adjust screen power". I have none of the apps installed that people have suggested. I`m only rooted with no system adjustment apps installed.

for me the problem would happen after I pressed the power button and the screen would try to wake up but the system with end up rebooting. After I unchecked "auto adjust screen power" the problem went away.
[Samsung Galaxy Tab Plus] StingerDog:
I unchecked the auto screen brightness shortly after I got the tablet because it made the screen so dark. Still had SODs after that.

Good news is still no SODs since going with auto airplane mode.
[Samsung Galaxy Tab Plus] LBJM:
Did you reboot after unchecking the box? Also are you using any of the native samsung power saving features?(I have it disabled) Have you upgraded your firmware via kies? I've disabled everything that relates to the screen including auto adjust brightness(I use max brightness). I change the brightness manually based on the program I'm using. Programs like fbreader and bsplayer have a built in brightness adjustment.
[Samsung Galaxy Tab Plus] StingerDog:
Did all of that. None of it stopped SODs.
[Samsung Galaxy Tab Plus] garyd9:
Is anyone who experiences the SOD issue using my custom kernel for the 6210? If so, the next version will include something that MIGHT help to diagnose what's going wrong...

Gary
[Samsung Galaxy Tab Plus] dtienes:
SOD Resolved - for me, anyway

It looks as if the problem I was having with the SOD had to do with my Micro SD card, Since removing it, I have not had a problem; placing one back in - I tried two different cards, and both had nothing on them - I got the SOD after ten minutes.

I'd love to get it working, but will track this issue down separately. In the meantime, if you are having this issue, you may want to look at the microSDCard.
[Samsung Galaxy Tab Plus] Lezziter:
I've never had any MicroSD card in my GT7+, and I still have SOD occasionally.

For me it really feels like the issue is connected to Wifi somehow. At a friends place over the weekend, I got like 15 SOD over two days while connected to his Wifi, sometime just 5-10 minutes apart. At home and on the train home, I didn't get a single one and still going strong two days later.

1. Which model are you using? (T869, P6200, P6200L, or P6210)

[Samsung Galaxy Tab Plus] naturefreak85:
I approve of your beer choice. I have one of them sitting in my fridge right now.
[Samsung Galaxy Tab Plus] Entropy512:
A 6210 with wifi off will almost NEVER wake up on its own - since the primary wakeup interrupt sources on most devices are the 3G radio (none on the 6210) and wifi.

So you blame it on wifi, but it may just be a suspend/resume issue that is exacerbated by wifi waking the device more often.

An interesting test case, try this:

ping -i 5 <ip address of device>

when the device is on wifi and sleep policy is never.

Battery drain will go through the roof, but the question is - will this cause more SoDs? If so, then there's a suspend/resume problem.

Once gary gets ramconsole working this will be easier to debug. Samsung has a more robust suspend/resume frequency handling mechanism than in Gingerbread sources, but something still seems... off... to me. (Or, never mind - it's just a fancier way of saying what our SoD patches do... Hmm.)

Try running garyd9's kernel and bumping the voltage for 800 MHz up a step. (Just one step)
[Samsung Galaxy Tab Plus] jasonemorrow:
1. p6210

2. pny 32gb ...also experienced sod with no microSD and maybe one sod with samsung 2gb from my infuse.

5. no

6. adb recognizes device as offline

7. both

9. n/a

kies recognizes device but cannot connect to it.

I have also noted that periods where I have the sod the time for the screen to come on after hitting the power button is longer than normal...up to 5 seconds

I am running your most current kernel.
[Samsung Galaxy Tab Plus] garyd9:
huh? It either sees the device or not.. What does "adb devices" display? if you do "adb shell", are you getting a shell prompt? If you send "adb reboot", does the device reboot? This is really important, because if adb can talk to the device when it's in this "SOD", then we can use logs and kernel messages to try and see what exactly is going on.... and perhaps run some other tests...
[Samsung Galaxy Tab Plus] jasonemorrow:
when i do "adb devices" is shows the serial number and then offline instead of showing the serial number and then device. Where the below says device it will say "offline". if i do "adb reboot" it says error device offline. I believe I got the same response with "adb shell".

[Samsung Galaxy Tab Plus] garyd9:
...how strange. I've never actually seen an "offline" shown with a serial number. Did you say that when this happens, sometimes the tablet will just wake up later? Or do you usually end up having to reboot it?

If it wakes up: please "adb shell", "dmesg > /mnt/sdcard/dmesg.txt" and then zip that file and upload it for me. Also let me know about how long it was between the tablet waking up and you creating that dmesg (so I know how far back in the log to look.)

If you have to reboot, please "adb shell",

"cat /proc/last_kmsg > /mnt/sdcard/lastkmsg.txt" and zip that file and upload it for me.

It's also possible that /proc/last_kmsg won't exist. If so, it indicates that the memory usually used to hold that data somehow got corrupted...

Thanks

Gary
[Samsung Galaxy Tab Plus] jasonemorrow:
It will come on later sometimes. I'm not sure how long, but I'll hit the power button with no response...look down a few minutes later and the lock screen will be on, no sound from it rebooting itself either. I'll wait to see if it will restart next time before I reboot to get you the logs...just may have to install adb on my computer at work :)
[Samsung Galaxy Tab Plus] jasonemorrow:
I had to reboot after the sod.

results was

"cat: can't open '/proc/last_kmsg': No such file or directory

hrmm. That kind of sucks. adbd is likely frozen and the ram_console is likely corrupted.

WTH is going on?!
[Samsung Galaxy Tab Plus] jasonemorrow:
I do notice that the lag for the lock screen to turn on from sleep is very excessive during periods when I am getting the sod's. For the past few days it has been in excess of 5 seconds. I have also started experiencing system and app fc's. I will try to take not of which. I just wiped dalvic, cache, and fixed permissions. The lag for the lock screen is non existent now. I'm interested in how long it takes to return.

Let me know anything else you want me to try. I'll keep this one as long as I can...I have a few days to exchange it still.
[Samsung Galaxy Tab Plus] garyd9:
Don't hold on to a bad tablet on my account. While I'm probably more curious WHY its happening than other people (who just want it to go away), you should make sure you have a working device first.
[Samsung Galaxy Tab Plus] jasonemorrow:
Unless I get them to stop I'll exchange it...have until the 25th. The problem is it's a PUZZLE! It's hard to leave it :) Besides I trust our devs like you to figure out the problem and the solution (if there is one) way more than waiting on Samsung, and if I can help...

Went ahead and Odin'd back to stock. Gonna hold off on the upgrade to see if I have any first and then upgrade over Kies...I did the direct download on the tablet last time.

I do notice android OS stays over 40%. I'm new honeycomb but on my Infuse with gingerbread it rarely got over 15% unless I have a bad flash or Tibu restore.
[Samsung Galaxy Tab Plus] gersen416:
15 days SOD free and much improved battery life since this post on Dec 23rd.

I'm comfortable now saying that Auto Airplane mode fixes the problem - at least for my 6210 by properly managing the wifi standby/restart process. I have also moved the tablet in and out of numerous different wifi hot spots, while on standby with the screen off, without a SOD.
[Samsung Galaxy Tab Plus] StingerDog:
Same here. With auto airplane running I've been SOD free since. Random reboots disappeared and battery life is now EPIC!
[Samsung Galaxy Tab Plus] truelies1:
Do you mean the "samsung wi fi auto sleep" caused SOD ptobkem?
[Samsung Galaxy Tab Plus] StingerDog:
Its certainly possible. We still dont know the exact cause for the SOD but there are some helpful folks here trying to nail that down.
