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

I have received my two "refurbished" S2's. My third and my wife's second. Set mine up and I did not have a SOD yesterday, will set up wife's today. However, half of the apps I use do not work. What an absolute failure. If our phones didn't have a few months of warranty left I would definetly go flash to 4.0.3 or Jellybean.

FYI:

 

Randall L. Stephenson

Chairman and Chief Executive Officer AT&T

 

 

It's time for everyone to send him a letter of complaint.  He won't read them, but maybe the sheer volume of complaints will get them off their collective behinds to fix this more than minor disruption in service.

I have tried almost every "solution" in this post with little success; disabling all AT&T apps seemed to do the most, but SOD still happens. 

 

However, I recently rooted my phone. Since rooting (and doing nothing else...using the same kernel and everything) I have not had a sleep of death. I'm not optomistic that this is a perfect solution (and I'm sure now that I said this I will have a sleep of death), but my GS2 does seem to be slightly more reliable now. 

 

Even if you're not technogically savvy, it is extremely easy to root your phone. I'll post back if I get a sleep of death, but so far so good - it's been 5 days without one.

Re: Galaxy S2 shutting off in idle mode

As someone posted above...after only rooting my phone, leaving everything else the same, my phone did not SOD in two days.  I kept checking my phone (as I have grown used to because of the random SODs) and every time I was suprized to see that it was still on!

 

I then wiped it and am now running 4.1.2 and its like a new phone, loving the multi-window.  Cant comment on battery life or anything else, but so far its looking great.

Re: Galaxy S2 shutting off in idle mode

I was talking to @samsungsupport and they suggested that I do a factory reset. Seemed like people in the forum had already tried that so I have yet to take the time to backup and do that myself. Also went into the AT&T store today and the guy was basically blaming Samsung, saying that if a factory reset doesn't help, then Samsung will need to be contacted. Ok thanks, guy.

As I predicted, immediately after saying that rooting prevented SOD, it happend within an hour. That being said, I have only had one sleep of death in the past week, so I don't think it hurt anything.

OK, my countdown starts now. I just flashed an alternative ROM. I'll let you know how it goes. Since I've have strings of a week or more of false success, I won't consider this fixed until I see it working for a month.


Just an update on my status... it's been 18 days, and no SOD.

Re: Galaxy S2 shutting off in idle mode

If you can roll it back to the 4.0.3 software I think you will find you have zero SOD's. I'm right at 30 days on mine with 4.0.3 and no SOD.

Re: Galaxy S2 shutting off in idle mode

So I've done better since disabling the two clock apps suggested, and google books, magazine, movies tv, qlik lite, and google+.   (I had disabled most of the ATT apps previously).

 

I went 13 days with only two SODs.--which like someone else stated, still points to the 4.0.4 update.

 

Still unacceptable, because yesterday I woke up w/ a dead phnoe, battery completely drained, and I had to leave without the benefit of being able to charge the phone, guess what, due to the SOD.  So I had to drive with an uncharged phone, charge it a bit during the duration of my drive, arrive at a location where I didn't have the benefit of continuing to charge it so that I could use it..   This is NOT why I have a cell phone--completely useless.

 

I cannot believe that this problem is being ignored so profusely.

 

This is not a bad coverage issue, this is a real issue with equipment and software provided by ATT/Samsung, which directly disrupts the service and equipment we all pay for.  Since all of us on this thread have ATT-provided phones and service, then the ball is on AT&T's court, and it doesn't seem to be moving anywhere.

 

This thread should not be marked as Solved.  There is nothing Solved about this.
