Galaxy S2 shutting off in idle mode

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.

Re: Galaxy S2 shutting off in idle mode

Hello All-

 

As suggested by another post on this forum, there are two Clock app on my SGS2 Android 4.0.4.  I forced stop the one that uses no memory and disabled it.  I also disabled the Dual Clock app.  By disabling these two apps, my SGS2 seems to be healthy again.  It has been two days without the random shut off problem.  I can't say this is THE solution, but it works on my phone.  My two cents....

 

BTW, I also disabled all ATT apps.

Re: Galaxy S2 shutting off in idle mode

I have the same, extremely frustrating behavior.  The 4.0.4 update installed over the air for me.  I have done a factory reset and full reformat.  Nothing, still experiencing the turned off screen freezing (SOD) issue randomly, once/twice a day.  I've also tried to pace the reinstallation of apps that I use to see if something fixed it, nothing.   This did not happen with 4.0.3.

 

I have Wifi turn on on my phone most of the time.   (And I also have a microcell.  And the reason I have to keep wifi on is because the microcell accelerates battery drain battery on 4G, and not a fix in sight for a problem that has been known and recognized for over a year).

 

What will happen if I call support is that I'll get the same story as others, let's exchange the phone, send you a refurb one, and the problem will still be there.

 

My last attempt effort before embarking on the downgrade to 4.0.3. is disabling the two clock apps suggested, and the google books, magazine, movies tv, qlik lite, and google+.  (I had already disabled the AT&T apps and it didn't fix the problem).

 

At this point, although always hopeful, I have a feeling these apps don't make a difference.  I think the issue is really between the OS software, the phone's wifi state, and the sleep state. I do know that the problem isn't specific to AT&T, because if you google around, you will see that at least Virgin and Vodafone have the same issue.  But, that doesn't shift ultimate responsibility from AT&T since my phone is an AT&T-branded Samsung and they should interact w/ Samsung and/or Google to try to fix what is clearly a non-isolated situation caused by a firmware update.

 

I will not accept that an S2 is a "legacy" phone and cannot be fixed.  Not asking for JB, simply asking for a reliable phone.  I don't see any fruitful mechanism to ignore my two year contract because a problem that is not caused by me could be resolved by "upgrading" my phone.   In the car industry, this is called a lemon.

Re: Galaxy S2 shutting off in idle mode

The att moderator "Jamileh" who posted on Jan 23 at message no 98 in this string seemed to imply a fix was in the works. But in typical att fashion there was no date and no word on what the problem was. I sent her a private msg with my email and phone no but no response. Kind of rude

 

I will note that if this cropped up in the update from 4.0.2 to 4.0.4 (as some suspect) it was pretty recent problem then. I could not swear this was a 4.0.4 issue. it does seem to be on wifi only but again thats where my phone spend most of its time

 

I wish I had left the refurb phone at 4.0.3 as it came from samsung but I let it auto update to 4.0.4. oh well live and learn

 

Also of the 3 att tech centers I visited none admitted to seeing ad s2 with this issue. amazing But they sure did have lots of refurbed s2's to hand out. makes you wonder

 

as for the micro cell I am glad I did not get one of those just to make up for att's crappy 3g coverage at my house and non existant 4g lte. You talk about lies those att LTE maps are fraudulent.!!!

Re: Galaxy S2 shutting off in idle mode

Anyone who takes their phone in to a service center should print out a copy of this thread and take it with them. Better yet, we should throw a BBQ and each of us can invite our respective Service Reps to come out, and we can introduce them to each other, and let them know that yes, there are others who have this problem. Apparently, AT&T has no means of communicating common customer problems intra-company.

The only thing that gives me solace is that all other telcos and big cos are just as ** up. Look at HP. Now there is a well run co. My brother worked there and said they could lay off 50k people and never notice they were gone.

 

On an individual basis the att people are pretty good. they try but its very bad decion making at the top by the "stock price inflators" that ** up the company. Hey how can we boost our stock price today over verizon? I know lets send out a press release that the lobbiest sugests! Lets says some cr_p about LTE or U verse that we know is false...

 

sorry to get off topic

In order to to arrive at a solution we need to know what causes the problem. Is it only 4.0.4 on only the s2? Or is it other phones? Is it wifi? what triggers it? Is there an accepted work arround we can use until the fix is issued? Will the fix auto download or not? Will the ix be in 4.0.5 or just a "patch"  If these cannot be answered then I am fearful that a fix is a long way off. Not just "weeks" (2- 50 weeks?)

Re: Galaxy S2 shutting off in idle mode

You really don't have to be an IT person to see based on these threads that 4.0.4 is causing the problem of the sleep of death.

Has anyone that posted in this thread ever have the sleep of death when they were on 4.0.3 or earlier?? I know I didn't, and haven't since I have been back on 4.0.3.

When I do have news, I will update this thread.

Re: Galaxy S2 shutting off in idle mode

There are at least three separate threads on this topic. The moderator has only posted on one of them. I have no idea what is causing the problem or how to fix it. I see some people in other threds that said it was a pre 4.0.4 problem. But knowing that its just 4.0.4 does not help unless there is some att approved way to go back to 4.0.3. Rooting the phone not an option for me as it voids warranty and I hear those people have their own sets of problems. I am begining to think the smart phone thing is not so smart unless you are a phone co charging for the data

Re: Galaxy S2 shutting off in idle mode

My S2 as well as my wife's S2 started shutting down by ltself in the recent 3 weeks... Really annoying as i missed few calls as well as morning alarms!!! Called customer care and they said they have power recycled and connected to a new network and this should solve the problem...... Nothing fixed it! Still we are seeing the problem.

Re: Galaxy S2 shutting off in idle mode

@jamileh, I think we all appreciate the fact that you have come here and told us that AT&T and Samsung are working on the issue. However, it is quite obvious that this is a big problem and from a paying customer viewpoint, AT&T isn't giving it enough attention.

Just to give you some examples of the kinds of issues this bug causes for us CUSTOMERS:

1) I had to be to work early this morning. On a typical day, I wouldn't worry too much about my alarm not going off because I would likely wake up on-time anyway. I was concerned last night and at about 4am I woke up, so I check my phone...it was frozen. For next 2 hours I barely slept because I kept thinking about that P.O.C. phone.

2) I was running late getting home from work. My wife had asked me to stop at the store. As I walked into the store I sent her a text message asking if there was anything more she needed. When I got home, I realized my phone had frozen and I never got her text. Now I am the P.O.C. who didn't get what was needed.

You see, AT&T and Samsung all want us to buy into this crazy image that we NEED these phones to live our lives. We pay hard earned money to be able to afford them and use them on a network that isn't always the best for us, but we deal with the negatives. WE SHOULDN'T HAVE TO DEAL WITH A P.O.C. SYSTEM UPDATE THAT BREAKS OUR PHONES.

You know what I would love to see? AT&T going back to $15 minimum data plans at 200MB. I would also love to see a NO DATA Plan option for Smart Phones that are no longer under contract. I'm pretty sure that will never happen and it probably won't cause me to switch carriers, but this P.O.C. system update and AT&T's lack of caring about it will.

end rant

Re: Galaxy S2 shutting off in idle mode

I got tired of my phone SOD-ing every few hours.  I missed calls, texts, and alarms...  Flashed to AOKP JB 4.1.2 and am loving it so far.  No bloatware, just a pure Android System... Smiley LOL

Re: Galaxy S2 shutting off in idle mode

I heard most 3rd party ROMs won't support MHL (usb-to-hdmi) or 64 GB microSD cards.  Can you comment on these and other items that you've found not to work in your new ROM, please?

Re: Galaxy S2 shutting off in idle mode

Here is one possible solution I am trying now. For about 18 hours, I didn't see the issue again.

It seems like it's power down/idle related issue per all the postings up to now. So I tried to overwrite the power down/saving scheme by:

 

Settings/Power saving/Custom power saving - ON

Custom power saving settings/Power saving starts at - 10% battery power

 

The thing I tried to achieve was by setting above configs the auto power saving/power down is not activated and only activated when there remains ony 10% of battery. I hope it overwrites the power saving mechanism that triggers the death. For the last 18+ hours I haven't got any issue yet. Hope this is the workaround of this issue.

Thanks!
