Galaxy S2 shutting off in idle mode

Recently, I noticed that my phone shuts off while in sleep mode. This just happens when I don't check it for a while and the display is turned off. When I do go to check my phone, it's unresponsive, even if I hold down the power button. So far, I've had to remove the batter every time this has happened in order to reboot it.

I just don't get what the issue is. I'm probably missing phone calls because I'm not even aware that my phone is turning off. I feel like after the ICS update my phone has had issues. I already performed a factory reset last week since I was having a problem with the notifications not ringing and vibrating, and now, this is happening on top of that. 

If anyone has any suggestions, that would be greatly appreciated.

I have a Samsung Galaxy S2 i777.

Oh, and another thing, I noticed that my batter is at 95-100% before it shuts off by itself, and once it boots up again it's down to 85-89%. I also feel like it might be an issue with overheating: I noticed that my phone feels hot after I've been using it for a while, like texting or using the internet, and then I set it down to do other stuff when I notice that it's turned off. My phone usually feels really hot too, and the case I have for my phone probably does not help either.

Hey all, 

 

As some of you have already noted, an update is available for the Samsung Galaxy SII. 

 

The update includes fixes for devices that may become unresponsive and/or power down while sitting idle on rare occasions. It also enhances security to protect against malware vulnerability. You will receive a notification on your phone to update. 

 

NOTE - You must have updated to Android version 4.0 to receive notification of the new software update

Since the OTA update on 3/29, no SoD.:smileyhappy:  Battery life on my phone seems to be about the same, and I haven't noticed any new issues.  So far so good!

Linda Jo, I went by my ATT store just minutes ago. They told me they dont have any sims to use. And if I bought one it would cost me about 30 $ 15 $ for new sim for gs2 they would have to activate it..and unactivate the gs3....THEN 15 $ for a new sim for gs3 to reactivate it........I will call customer service and see what they say!

Thanks Wanda......I like that you're doing the leg work for me :-) See if they'll tell you how we can do it without a SIM card. Let me know what you find out.

Hi Everyone,

 

I hope I'm the only one, but a few days after the update I am still getting sleep of death!  Happened twice in a row yesterday.  But now there's another NEW bug!  Randomly, while on a live call, the phone perform a soft reset.

 

I've waited months for this update and it's not working for me.  Am I the only one?

 

AT&T offered be a pathetic $15 credit to compensate, and gave me the option to recieve an "early upgrade" as long as I sign another two year contract.  Neither of those options seem sufficent enough to me.

 

Let me know if you are still haveing SOD after latest update.

 

Cheers,

Joe

Wow... sorry to see an SoD pop up again  :smileysad:

 

I have 70 hours without an SoD and my battery use has gone from fair to excellent.  The battery chart now looks like a nice gentle hill as opposed to Mt. Everest before.

 

Still having weirdness with the text message icon... says there's a new message for hours after it should.

Other than that, no negatives to report at this time... well, other than ATT support and complete failure to properly address this issue 9 months ago  :smileysad:

 

Just FYI on my setup... I left all the apps I had disabled as before (especially ATT junk).  I put in a fresh battery and did a cold restart after the update settled in.  Frankly, I don't think I've every gotten to 70 hours on a charge before and my battery is currently at 55%.  Granted, it was a holiday weekend and I only had a dozen or so calls and texts plus very mild internet usage. Still... I'm impressed so far.

 

Too early to call it "fixed" though... especially with ATT involved  :smileysad:

Soooo over this - just had SOD twice in the last 20 minutes.  Come October it's onto Verizon for me.  Can't believe I'm forced to wait six months, unbeliveable!

No SODs but I do have a new problem. My phone and Google play settings are set to only update apps when connected to wifi. When jogging this morning all the att apps updated over data. I double checked my phone and Google play store settings and they both were set to update over wifi only.

So now I have used 25% of my monthly data on the 1st day of the month. Yes I have disabled the crappy att apps but I should not have to I should be able to delete them.

Took my phone to At&T to reflash 4.0.4 because I had nothing else to lose and my phone crashed 3 of their computers. This last update did dada to me. If my phone is not on a charger it will just die within 15 minutes of 100% battery

OK... Thought I should post an update because this is just amazing!

I have made it 119 hours since last charge/battery change and still have 9% battery left.

 

First and foremost, NO kudos to ATT or Samsung.  Shame on them for not fixing this immediately.

It took the determination and exasperation of thousands of customers, many now lost to ATT, to get a response.

 

To recap my “conditions”:

 

Usage in this period was lower than “normal”.  The holiday reduced work-related calls to near zero.

A couple of long phone conversations, a half dozen in the 5-10 min. range.

A dozen or so texts with photos etc.

Light web surfing, weather and e-mail checking.  Close to “normal for me”.

Low app usage… Accuweather, some googling around.  Nothing heavy at all.

Mostly 4G with half hour max of WiFi use.

 

I have updated my phone as they came out and the SoD “fix” was the latest.

I have a wall-charger and extra batteries so I usually swap batteries rather than charge the phone.  Unless traveling then just depends.

So, phone usually gets a hard reset when battery bottoms out.

 

Apps/Functions Disabled:

 

I have the Developer Options; Do Not Keep Activities set ON

 

Only turn on when using, but used both for a short while during this period:

GPS

WiFi

 

Never turn on:

Sync

All Power Saving Options

 

Disabled Apps:

ATT Code Scanner

ATT Family Map

ATT Hot Spots

ATT Navigator

ATT Smart WiFi

Buddies Now

Clock (the odd extra one)

Dual Clock

Exchange Services

FaceBook

Media Hub

Movies

myATT

Social Hub

Social Hub (another piece?)

Synchronize

Talk (the Vingo thing)

 

 

So, there you have it… progress FINALLY!  I feel exonerated and relieved. 

Exonerated, as we all should, that we managed to get ATT to do the right thing.

Relieved that I have had NO SoD in the last 119 hours.  The phone actually works!

 

Well, so far so good… but others are still having issues that need to be monitored.

Trust is something ATT did their best to lose.  We shall see what happens in the weeks ahead.

Okay, so Maavalous posted some incredible battery stats. Does anybody else get anything close to that off the AT&T stock battery? You charge it to 100% and use it like Maavalous does (including some calls, some WiFi, some GPS, some web surfing, some weather checking - sounds like a lot of usage to me!!) and you still have 9% battery left 119 hours (5 days!!) later....I'm wondering if it's the new battery.

 

I have a new GS3 that is only about a month old and I have all the same apps disabled, I keep data, WiFi and Bluetooth off, I charged it to 100% and took it off the charger at 7am yesterday morning, no useage to speak of (I listened to one voicemail) and I am at 11% after 40 hours.

 


Unless I have everything turned off and put the phone in airplane mode, this is how the battery drains.

 

What about everyone else? Do I just have a bad battery??

Yeah, it's been nice to feel confident that every time I go to turn the phone on, it turns on instead of being greeted by nothing.

I'm sure we'll never know the details unles the poor underpaid guy who actually fixed it decides to post it here.

 

But, here's what I have seen that tells me it was definitely something ATT had done... as far as I'm concerned, we had ATT malware on our phones.

 

During the painful months of trying to figure this out, one thing I took to checking on a regular basis was the Battery usage chart (when you tap the small chart and expand it).  The very first thing I saw after the update was a HUGE drop in the top line "Mobile network signal".  It went from nearly a solid bar to actually having gaps that corresponded to when the phone was asleep/idle.  We are talking a LOT of activity stopped and more accurately represented valid times for the signal to be active.

 

Makes one wonder... what was ATT doing??  Well, aside from draining our batteries...

To Linda Jo...

 

I think the S3 is a 4G-LTE phone correct?  In my never ending search for solutions to our S2 SoD problem, I found a lot of posts about LTE draining batteries.  1) It uses more power when active.  2) It wastes a lot of power searching for a signal if you move out of range of an LTE tower.  If fact, there are now apps out there with ability to force LTE phones to drop back to just 4G and improve battery life.

 

Just a thought...

 

Oh, for the most recent tests (as I noted) I am swapping back/forth between two batteries and using an external charger.  I think the external charger ($6 on the web) actually charges the batter much better than just plugging in the phone.  Plus, that means the phone gets a hard restart every time I swap.

Could be having some percentage of affect on my battery life but certainly NOT explaining all of why I'm having such luck.

The fix they did does NOT resolve the screen of death issue. I still get it 3-5 times a day and when I reboot I typically see anywhere between 40% - 60% battery drain.

AT&T has been negligent in addressing this issue because they know most will upgrade their phones to get around the problem.

I'm waiting until my contract is up and going to another carrier since they've essentially breached the contract by pushing an update that created the problem. Then don't bother to fix it.

Good bye AT&T!

The update did fix the SOD for me (although my battery life hasn't been that great) and seems to have fixed a bunch of people's phones on here. I wonder why there are those remaining that it hasn't worked for.

It has been exactly one week for me since I applied AT&T's patch and I have not experienced any more SODs.

The battery life seems good. AT&T had no issues issuing partial credit for 3 months.

 

Sorry to hear that some people still experience the problem. First and foremost make sure that the patch is applied to your phone, in Settings->About phone-> Baseband version should be I777UCLL6.

If not, you dont have latest version.

 

Somehow I think it is the same set of people that had SOD on 4.0.3 version of Android. I never had it on 4.0.3, it only started for me with 4.0.4. I think your best course of action is to push and get a replacement phone from AT&T.

good luck

Max

Agreed Max.  I'd also add to make sure the update was the most recent version, from March.  Due to the SOD issue I received a refurbished S2.  It was on version 4.0.3.  When the most recent update was released, the update would not allow me to go from 4.0.3 to the release in March.  I had to apply the "bad" update from Dec '12, then apply the Mar '13 update.

 

When I applied the Dec '12 update I literally got a SOD within a couple hours.  After I applied the Mar '13 update I've had zero SODs.

 

My guess is those that are still experiencing SODs have only updated to the first version of 4.0.4.

For those of you who received a replacement refurbished GS2, have you swapped out your SIM to use it in your original GS2 to update it? Then you'd have two working phones and you could sell one to recoup some of what you paid for service, and didn't receive, for the last three months. I'd really like to be able to apply the update to my GS2 because I use it for most of my game playing and I still get the occasional SOD, although without it searching for reception, I get great battery life. I only use it for WiFi - the rest of the time it's in Airplane Mode.

 

And for Maavalous, I found some YouTube videos on how to switch off the LTE radio and I did it yesterday. I will wait until the work week, so that I use it the way I usually use it during the week, to see if switching to "WCDMA All" improves the battery drain. My GS3 doesn't show a band indicator, so I have to assume I am off 4GLTE.

For me, AT&T required that I send my old S2 back in order to get the refurbished phone.  They provided the shipping materials.  Not sure how you managed to keep your old phone Linda Jo.

NormChar, I am not sure either, but I assume it's because I didn't have a contract since 2007 and they made me sign a new 2-year contract. I guess it's akin to the people who have gotten a credit on service for all or part of the three months it has taken AT&T to offer a remedy.

 

It was not offered outright. I was offered all the same alternatives as everybody else, but because I am the contact person for my father who is in Stage 4 kidney disease, I missed a full day of desperate phone calls, someone at AT&T recognized that after my 7 previous calls to AT&T throughout the 3 months, had my father not survived this incident, it would have resulted in a legal issue they wouldn't want to get into with me.

 

It just comes down to speaking with the right attitude to the right person.

@Linda Jo

What you need is a micro sim adapter (cheap, $1.00 or less). The adapter is mini-sim sized and the center is cut out wherein you would insert the cut down micro sim in the center. Just insert the adapter in your SII and you're go to go. Your visit to AT&T to solve this problem was a joke (to put it nicely).

 

Go to GPlay and check out these two free apps - Simple Mobile Data Link and Data ON-OFF. I use them both on my SII (useless now)  and SIII. I'm on wifi only, no data plan.

 

Any accounts sync or apps updates - do them manually. It'll help your battery life.

A few months ago, I had gotten an AT&T device store to roll my SOD-filled 4.0.4 version back to 4.0.3 to save my sanity with respect to missed calls.  Now that the "fixed" version of 4.0.4 has been out for over a week, I thought I'd upgrade.  So I did a check for updates and installed, only to find I'm back at the bug-filled version!  And now the updates mechanism tells me I'm current, and I cannot check for updates for another 23+ hours?

 

So, all this time later and AT&T is still serving up the bug-filled version and making people live with it for at least a day?

 

In case this is useful to anyone else:

Android version 4.0.4

Basband version I777UCLK3

Kernel version 3.0.15-I777UCKL3-CL1174199se.infra@SEP-112 #3 SMP PREEMPT Mon Nov 26 22:50:34 KST 2012
