Welcome to the new AT&T Community
We've got a fresh look! Take the tour to see what's new.
Since yesterday I updated to Android 4.0.4, My phone has deadly slept for two times.
It powered off automatically--even I was not aware when it shut down--and could not power on unless I took the battery off and put it back to turn the phone on.
I had such experience on Android 4.0.3 but it was not so frequent--about once or twice per week.
Very disappointed with this new ROM.
How to sovle this problem?
Waiting for Jelly Bean, although ATT will not release it probably.
Well the phone turned itself off twice within in the hour today. ATT said that they are aware of the problem and would call me back to see if the phone is still acting up. If so, they would send out another one and told me not to do the OTA update. What a company.
Oh no! I've had a very stable phone for many months until I upgraded to 4.0.4 a couple days ago. Now it has exhibited the "sleep of death" symptom 3 times, and occasions of massive battery drain (from 70% to 10% in 3 hours).
Is there a way to revert to the previous version? This phone is critical for my work.
Same problem with my S2. It has shut down 3 times today on me for no reason. Did it a couple times a week with the old version. Would like to hear what AT&T's fix is for this. I am not eligible for an upgrade or I would consider going back to CrApple.
I called ATT and they confirmed that there was a bug in the software an after telling them enough was enough; I told them that the next step was to go to Verizon. They are now sending out a HTC phone. Funny because they said it would be an older inspire 4g, but the email states that they are shipping a HTC one x. It does not matter to me. Just a phone that does what it is supposed to do.
I don't want a new phone. I want my phone to start working. Instead of shipping out new phones it's probably more cost effective to just actually roll out a new patch.
I don't think they actually care. They'd rather people purchase phones than support "older" phones. There is a reason they rank dead last in customer service every single year.
Same problem here I have had to reset 4 times in past 24hrs, sorry now 5 times! as I went to check my phone.
It goes to sleep and never wakes up until I remove battery. This rarely happend before the 4.04 update.
My solution after being humilated twice in 6months by AT&T and problems with SGS2 updates is to leave ATT after being a loyal customer for over 7years.
I will advice any Galaxy SII user to not update till this issue is fixed if there will ever be one.
If you are running something in the background, try turning it off and see if the problem goes away. I was using Juice Defender on my GS2 with the Task/Ktoonsez JB ROM, and it was getting the "sleep of death" once or twice a day. That went away when I disabled Juice Defender.
This is what I'm going to do. I went back to 2.3.6 and will spend tomorrow backing up data and moving on to a custom ROM.
You have to root your phone and basically force the original phone's 2.3.4 version onto it. Look around in Android custom firmware communities. It's very tricky to do and even I found it confusing to do as someone who's pretty technologically versed. Also it voids your warranty, not like I had any though since my S2 was refurbished.
I found a custom version of AT&T's 4.0.3, hopefully one that doesn't go into the sleep of death. Even so at least 4.0.3 only went into "sleep of death" once a week as opposed to every hour with 4.0.4.
First let me say the only way to prevent the sleep of death is to root the phone, but the problem with that is the camera won't work properly. Going back to official 4.0.3 is quite easy and doesn't require going back to 2.3.4.

I'm having the same problem, come on ATT! My GS2 was great with 4.0.3, but shuts down with 4.0.4
It is now March 8th, and my phone kills itself at least 4-5 times a day. Constantly having to hard reset my phone is really getting old. And what's fun is that I just used my warrenty, with all of 8 days left, to replace my original GS2 that had a faulty USB hub. The refurbished phone they sent me came preloaded with 4.0.4, and I am about ready to throw it at a wall and buy a Nexus 4. Good job AT&T, your need to install endless amounts of bloatware and the inability to let the OEM manufacture put out updates, and instead doing it yourself, has killed a otherwise wonderful phone. GG.
