Solution for Galaxy SII SGH-i777 4.0.4 update issues

I think I've fixed my Galaxy S2 problems!  It has been completely stable, very responsive, with great battery life for 4 days.

After the 4.0.4 update, I saw the all the problems being described here: spurts of extreme battery discharge, spontaneous reboot, but most often "sleep of death".  After the "sleep of death" episode, the phone indicates the battery is dead if you hold the power button.   But usually, as soon as you plug in the charger, the battery indicates less than empty, and the phone will boot.

Per AT&T's advice, I removed lots of apps (mostly geeky, system-oriented apps).  No luck.  Then I did a factory reset.  Better, but no luck - still saw "sleep of death" occasionally.  Unacceptable, as my job depends on the phone.

On a  hunch, I tried something else: disabled several AT&T built-in apps, being specifically concerned about "AT&T Smart Wi-fi".  

Background: I remembered that several months ago I saw this app in the Play store, and it looked useful.  I installed it, and my phone became unreliable.  I didn't recognize the problem immediately, because I suspected my new SD card was the culprit.  After two weeks, I uninstalled the app, and the phone became stable again.  A few days ago, I noticed "AT&T Smart Wi-fi" came along with 4.0.4 as a system app, so I disabled it and the phone has been great since.

Actually, I disabled most of the built-in apps (you can't uninstall them, unfortunately), but I suspect the Smart Wi-fi app was the culprit.disabled_apps.JPG

An update to my post on fixing my GSII problems by disabling AT&T apps:  After a nearly a week, the phone is mostly stable.  I have seen 2 sleep death episodes, and one may have actually been my fault - battery usage has been so low recently that I forget to charge the phone, and the battery may have died a natural death during the night!  But the other was the classic sleep of death, so the problem is not completely gone.

On the bright side, I have never, since buying the phone 14 months ago, seen such good performance and low battery drain as I see now.  Apps are very snappy, and a battery at 100% in the morning will drop to around 70% at the end of the day with my normal usage pattern.  I used to charge it at every opportunity.

I certainly wish I could count perfect behavior, but I don't think we're there yet.  I'm considering making a daily habit or restarting the phone each morning, to see if that helps.  I remember it being a good idea on older, less stable versions of Windows.

In any case, be sure to disable the apps referenced above, and at least the "AT&T smart wifi" app".  Like others, I am appalled that AT&T produces something so detrimental to the phone experience, then has the gall to force it into the OS, and subsequently seems clueless that it is a huge source of problems.  It really motivates me to pursue a Nexus phone from Google next time around.

Ok, tried a few, including the AT&T Smart WiFi app, but that didn't work. It failed a few hours later. So, then I went after the rest. Noticed that the permissions of a couple included "change wifi state". Got those disabled and matched what you had and now it's gone almost a day without a "sleep death". Thanks for posting this. I was about to get rid of the phone.

Turning off AT&T bloatware

I posted this idea a week ago.  Here's a followup report: better, but not a satisfactory solution.  Here are some details I posted in another discussion on this forum:

 

"I am about to give up on 4.0.4.

 

The reliability of my phone is critical for my job!  If I miss a call at the wrong time, it will cause me and others big problems.

 

I've spoken to tech support twice, and done the following:

 

  • Removed all but the most benign apps.  No improvement.
  • Factory reset. No improvement.
  • Disabled AT&T apps (I was the one who posted the suggestion a week ago).  Big improvement, but the phone is still not reliable.

I'm now seeing only the "sleep of death" issue.  The symptoms are: the phone sleeps with plenty of battery charge remaining.  When I try to wake it, no response.  When I try to restart it by holding the power button for 10 seconds, the battery charge icon shows a completely drained battery, and the phone won't start.  But if I plug a charge cable in, after a few seconds, the battery icon will show a significant charge and I can start the phone.

 

The "sleep of death" is happening up to twice a day, but usually once or not at all.  Still not good enough - woke up this morning and found the phone dead, and immediately was concerned I had missed a call from my job.

 

I've had the SGH-i777 (AT&T GSII) for more than a year, and love the device.  Unlike many, I'm not an AT&T basher.  I've had a wireless contract for 17 years, and have always been pleased.  But this is unacceptable, and the lack of any sense of urgency on the part of AT&T is disturbing.

 

Next option is root/ROM.  I have no desire to do this, as it is time-consuming and has its own problems.  But I have no other ideas, if AT&T doesn't step up their customer support.  And if I have to solve the problem on my own, I will have no interest in continuing my contract with AT&T.  Seems the trend is purchasing a phone outright and using an MVNO - so be it."

Hi, I have been using a brand new Samsung Galaxy S2 since April 2012. My phone had many problems such as GPS not working, freezing and it was replaced in September 2012 by AT&T with a refurbished device of the same model. The new phone also had problems such as freezing or default apps do not respond and closed, even though the GPS was working most of the times. Then I installed this new 4.0.4 update hoping that would solve the problems. However, the problems still exist. Sometimes the phone keeps shutting down by itself, sleeps to death, freezes and so on. I had another Galaxy S2 of AT&T with the similar problems too.

 

Whenever I called AT&T, the customer service told me that there is no reported problems or known issues with Samsung Galaxy S2s. I think this is not true, as I see many other customers are having similar problems. This phone was advertised as a great phone, but I think it has a lot of unsolved problems. 

 

Today, the customer service is sending me another Galaxy S2 and I am not hopeful at all. I am tired of using this phone and I will never buy another Samsung phone.

Update: The phone i777 I received from AT&T today also has the similar problems. It looses data connection or gps in the middle of the city for no reason. After restarting it, the connection works again at the same location. What a great phone.

I had similiar problems on my SGH-i777 after the 4.04 update. I am not sure if this will work for you but I seem to have had success by doing the following.

  1. going into the developer menu and restricting the number of applications that run in background.
  2. going into the developer menu and checking the box that forces applications to close when I exit them (btw...the developer menu is a part of the settings menu.
  3. doing a battery recalibration. You can do that by: a) shutting down the phone, b) charging the battery to 100% with the phone off, c) removing the battery from the phone for 3 minutes and d) replacing the battery back into the phone an restarting it. (Note that you will need to do steps 1 and 2 listed above any time you do a phone shut down.)

This seems to be working for me.

Just for the record, I posted this idea originally, and although it improved the reliability of the GS2, it didn't completely solve the problem.

Yesterday, I spent half a day learning the root/ROM process, and installed the SuperNexus ROM on my SGH-i777. Not something I wanted to do, but AT&T forced it on me. I'll remember this imposition at contract renewal time.

So far, it's great. I'll report back if I have any problems such as runaway battery consumption, or sleep of death.

I'm curious, I am not seeing the way to Disable these apps.  In my Applications list, like your screen shot, I do not see the word Disabled.  And I do not see a Disable option.  Does this ability require my phone to be rooted?

Nevermind, I found it.  I needed to Uninstall All updates first, then it gave me the Disable button.  All good now.  I'll test this to see if it helps.

 

Thanks!

I haven't had one SOD since reset and disabling all ATT apps. I understand it didn't work for you but I'm very happy with my GS2 again. Thanks

I have disabled most of the ATT apps that I can find and lots of the crap that was on the phone. So now we shall see

 

In my opinion its should be illegal to use the android OS and allow goofy cos like ATT the ability to lock their apps in

 

Once the 90 day warranty expires on the this factory refurb ill just root the phone if this SOD keeps up

 

my other post in another realted string:


 

Re: Galaxy S II random shutdowns/enormous data usage[ Edited ]

My stock s2 bricked in the first 60 days. (purch nov 2011 at costco). So they gave me new phone. it was fine for 8 mo then about 3 mo ago I was getting the random shut donws. I have to reboot (press vol key and power key to restart) No reason for it. totally random. Sometimes goes 3 days no prob. Sometimes does it three times in one day. Always when phone is idle and screen is off. Phone is shut down and recharged nightly. No weird apps. no rooting. Its now on ICS 404. So took the phone in on the even of the 1 yr arranty with att and they gave me samsung factory refurb phone and a new batt. Three days later I got the same problem. So now one by one I am removing any non google apps to see if its an app problem. I have 90 days warranty on this refurb phone. I guess I am just having bad luck. Otherwise phone has been great

 

I wish there was a quicker way to determine problem. I have to rule out hardware as the refurb phone doing same exact thing as last phone on the same OC ICS 404

 

One thing that I do note is that its almost always on wifi when ot shuts off

 

I do not have any high data usage. Usually well below 300 mb mo. I use navigation a lot and all the google apps but its on wifi a lot

I have tried disabling the AT&T bloatware and it has improved the SOD from 5 or 6 times a day.  To once every day or two.

After trying all different suggestions regarding this issue, it appears that the only effective solution is to flash the phone back to 4.0.3. I did this using the procedudure and software tools found on GalaxyS2Root.com. I did this about a week ago and have not had one crash/SOD episode since. I think that I will not EVER upgrade the firmware on this phone again. Too many headaches! Hope this note helps the rest of you.

I was super excited this morning when I received the update message, I figured it was the update finally to 4.1 (Jelly Bean).  However after the update my SGH-i777 still states it is 4.0.4....grrr.  I have been witnessing all the above problems with my S2.  Did anyone get this update?  Am I far behind?  I tried even syncing through Samsung Kies, but now it says that my firmware is too out of date for Samsung Kies...WHATT??

I noticed every time in recovered from one of these episodes , the play store would be downloading an update. I disabled automatically update apps and I have not had any problems for the past 3 days. Hopefully it stays this way! I also got the mystery update today... waiting to see if it does anything different...

I am curious if you went with SuperNexus, which version you installed and how it worked out?  I too am tired of the crap that AT&T forces on you (anyone else sick of the delay waking the phone and seeing that stupid AT&T logo in the upper-left corner!) and waiting forever to get JellyBean.  I put CyanogenMod on my Galaxy S - original - the phone Samsung/AT&T said wouldn't get JB - CM works great, albeit a little slow. Unfortunately, CM is really behind on getting and official JB based MOD for the S2.

 

FWIW, the patch to fix this problem won't install on my phone.  I tried it a dozen times last night.  Even did a "factory reset" - it downloads fine, reboots, gets to 67% and says "Update is failed", then reboots.

 

I always suspected the problem is with the additional crapware AT&T forces on us with 4.0.4 - I have gone through and disabled everything I don't want.
