[Q] Phone occasionally won't wake up - Galaxy S II Q&A, Help & Troubleshooting

I've had this problem for a while even on the original firmware. I'm hoping some whizz in the XDA forums can shed some light on it ?
Randomly, my phone won't wake up AT ALL. It's still running, but the screen just won't come on.
I'm currently on the Litening v1.1 rom, but I think that's inconsequential.
The only fix is to take the battery out and replace it and then it boots fine.
I decided to delve a little deeper. I installed an sshd service so I could attempt to ssh in if it happened again, which it just has. I ssh'ed in and managed to get the log file (that I've attached to this message).
I also got a couple of screenshots showing that the system monitor service had failed and that when the phone was rebooted, something had really drained the battery.
I also took a screenshot of what had consumed the most cpu while the phone was in the sleep of death......
Also attached to this post is the log taken AFTER the problem had happened, and it seems to show me pushing some keys to wake the beast up, but no joy.
Any help gratefully received !!!
Thanks in advance !

I have the same problem but i haven't been nearly as thorough in my investigation because I only got my GS2 2 days ago. It's happened at least 10 times since then. I've been searching forums and this is the first post I've found that seems to be the same problem. Can anyone help?

Umm,,try this..
It may be due to some kinda App..try uninstalling the apps which u installed or used just before this problem occured..
It happened with me too,,just one time though,,,when i installed an app(Night Vision..or something ),,,,i guess it causes some kind of sensor malfunction,,,,
I removed the battery,,,then reinstalled it,,,switched on the phone,,deleted the app,,,Ran an Antivirus(AVG,,,not a good one),,,and it showed me some kinda "suspicious message" warning,,,i pushed the fix button,,,and thats it,,,,
No problems so far..*fingers crossed*...hope it helps.

Thanks, I'm pretty sure it's an isolated problem and I've just been very unlucky.
Phones4U are replacing the handset.
My phone has not woken up out of sleep since about 24 hours ago. It's not shutting down, it's just not re-enableing the display or touchscreen after being in sleep mode.
I have tried a factory reset but that didn't help.
Just in case anyone has the same fault, there is no fix. Send it back.

My phone doesn't wake up sometimes. This morning it happened again and I had to take the battery out and put it back in. It's annoying but the only problem I have experienced thus far.

Update from me.........
I haven't had this issue for a long time now. I am now running litepro 1.5. I also disabled fast dormancy or whatever it's called so not sure which of the above fixed it.
But, what is strange is the problem originally occurred on the stock rom (orange) and a litepro rom ?!?!
But, litepro 1.5 seems to have solved the issue for me.
Now, reluctant to try a new rom, as it's a pain of a problem when it occurs. Hope others find a solution that works for them.

Touch screen not working - even in Windows

First off: Let me clarify that I searched the forums but could not find any thread that described my problem. If this has already been answered, please help me close this thread.
I'd been running the Desire V5 Android build with Jul 23rd zImage for a while now without any problems.
I recently started having lag, slowdown and non-responsive touchscreen (I'd have to wake my device many times before it started responding). Last evening, it stopped responding completely. I pulled the battery and booted back to Windows, only to see that that touchscreen wasn't working even there!
Worried, I flashed the shipped ROM for my T-Mo HD2 - no SPL (RUU_Leo_1_5_TMOUS_2.10.531.1_Radio_Signed_15.34.50.07U_2.08.50.08_2_Ship) and the touchscreen started working again.
I thought everything was fine and started Android, and found that the touchscreen stopped working.
Now, even reflashing the shipped ROM doesn't seem to do anything.
What can I do? Should I do a Task <what>? Has anyone seen/had this problem before? I'm hoping it isn't defective hardware.
Ok, got it working
Ok, I got it working again.
1. I did a Task 29 using (http://forum.xda-developers.com/showthread.php?t=644781&highlight=Task29, ShaDrac's repack).
2. Flashed a ROM (I used the T-Mobile stock ROM, but I guess anything else would have worked too).
Hope this helps if someone else faces the same problem!
I wonder why this happened, though.
Im glad you got it fixed
Maybe you can put a [fixed] or something in the thread title to help others?
Just a thought

Guess I spoke too soon! The problem is back, and this time I didn't even boot into Android. Guess it's the hardware. I'll just have to install the stock ROM with SPL and go back to T-Mobile!

I have the same problem. Right now, I think it's the hardware. Just sat down the other day with my HD2 in my pocket. Maybe it has been bent or something like that. I don't know....
the same thing is happening to me..at first if i locked my phone and the screen wudnt respond..now it wont respond at all..i tried flashing it..still not working!!..has to be something with android..i installed a new android build the day b4....or the new cookies home tab replacement...i installed that too...dont kno wat to do now...
I have had the same exact problem.. the touchscreen stopped working when my friends and some chicks were taking pic (EMBARASSING ) ).. and i even tried it on windows mobile, didnt work. tried that yellowish button in the back of the phone to reset it.. nothing happened.. so i plugged in my phone to charge up (IN WINDOWS since i couldnt boot into android.) It was charging the whole night, and when i woke up the issue is gone, havent had it at all after that.
i am almost positive its hardware; you all are describing the same exact problem i had a month back. i finally had enough and called htc, found out the phones are warrantied for a year and sent it in for repairs. took about 3 weeks and my phone was back, 100% fixed and cost me nothing out of pocket (well except the cost of shipping the phone to them). instead of fighting it, call htc......i was so glad when i got this problem fixed it was so damn annoying! good luck all
Thread moved to Q&A.
I had the same problem a few months back. It is certainly hardware. I had this problem before android was available on our hd2's. I task29'd it, flashed to stock rom, and reverted to stock spl. Nothing fixed it so I had to send it back to T-Mobile.

[Q] Can someone help me? My phone keeps freezing and buzzing

Hello everyone,
To be honest, it's been some time since I've been here, back when I knew how everything on this forum worked...
I kinda forgot, so I'm just posting this HELPME!? thread
This is my problem:
About 1.5 years ago I downloaded a ROM, and put it on my phone, and it was working just fine. However, 3 weeks ago it became really annoying, i'll explain what my problem was:
My phone would randomly freeze when i was doing things, these things could vary from "sending a text message" to "opening my 4th opera tab".
After that it wouldn't respond unless I reset it. However, when starting up again after resetting it would do a few possible things.
1. It's freeze at the first startup screen.
2. It's keep switching between unlock and "pin-screen", and when it was working again, it'd freeze.
3. It'd start up, and after about 5 seconds buzz like 5 times, then freeze.
When i left it on frozen the battery and phone would turn very hot as well =(
So, I tried a hard reset, but that didn't work.
After that i went to the following thread:
http://forum.xda-developers.com/showthread.php?t=591784
I followed the instructions, installed the right Radio (2.12.50), and installed the ROM ( Energy.Leo.21916.Sense2.5.NLD.Cookie.2.0.Jul.07.7z ).
I remembered how to intall these things, so I think i've done that right.
So, after that it seemed to be working fine, and I was really proud and happy.
Now my phone has frozen again, and starting up was an issue again...
Does anyone know what my problem is? And what would be even better, what i can do to solve it?
Please let me know <3
Adios <3
Little Update:
So, I've been carrying my HTC HD2 around with me again, and then it started again...
It froze when I tried to send a text, and after that would freeze or vibrate (a few times) during the start-up...
It's really anoying =( If I'd have to estimate my phone's uptime a day...
It used to be 24h a day, now it's more like... 4 hours a day, with 2/3 hours of trying to get it working :Z
That could be hardware related. Possibly processor overheating. I would download the latest stock rom and fash it to see if it sorts the problem. If not it will need to be sent of to HTC to be replaced.

[Q] Phone keeps shutting down

Hi guys.
My phone shuts down at random moments. I can boot it up again by holding the power button for about 10 seconds. Sometimes, not always, the phone feels hot and batterylife dropped. I have been struggling with this problem ever since i got this phone. I hoped to solve it with installing a new kernel and rom. I am now on Slimbean 3.1.0. The phone was initially on XLQ6 4.0.4. This didn't change anything, unfortunately.
I have also tried:
- removing external SD
- placing a new battery (which has no room to move, in case anyone suggests the battery might be moving)
- wiping caches
The strange thing is that my friend has bought his i9100 together with mine in the same order. He is also on XLQ6 and is experiencing the same issues. Less often than me, however.
My smalband is still on XLQ6. Is it possible that this causes my problems? Or is it more likely that my friend and me simply bought phones from a bad batch or something (hardware related)? I really don't want to send back my phone. That is my absolute last resort.
EDIT: Problem solved! Installing the application "Load Monitor" and enabling the "wake lock" function has done the trick. No more shutdowns or reboots!
Anyone?
2 devices with the same issue?
I'd be at the store where I bought it right now.
I will do that when I am absolutely sure that it is hardware related. However, if anyone has a potential solution I would really like to solve this issue myself.

Same with me. change from 4.0.4 WLPT to 4.0.4 WLPY but problem still presists.
Does anyone know if changing smalband (if that is possible?) could make a difference? Because that is the only similarity to the original state of my phone. A lot of AT&T users in the USA experienced the same problems also with 4.0.4. However, nobody can come up with a solution.

If it is heating near the camera, it's facing death soon.
If it is new and warranty isn't voided, why not flashing the carrier ROM and get a new one?

Because I don't like to lose my phone for a couple of weeks. And I prefer to fix these things myself. I have seen so many topics about this on XDA and Google. There must be a solution to it.
Is it possible that these problems are caused by my modem? That is the only unchanged thing since I have had this phone.
I might have found a possible solution. I've read something on a Dutch forum about sim-cards causing these issues. So I have placed a new sim-card and the problem hasn't appeared in the last 3 days. Before that, the problem was occuring about 3-6 times in one day. It's too early to say this has solved my problem, but it definitely made a difference so far. If it keeps functioning perfectly for the next couple of days I will close this topic.
Symptoms were merely reduced. Phone still shuts down approximately each 2 days. Much better than it was before though. Why would a sim-card change reduce, but not solve the problem? This is starting to hurt my brain.

You may experience sleep of death. What WiFi chipset do you have? I had the same issue on a Murata Wi-Fi chipset.
Yup, Murata chipset. I've googled some more on SoD. I have now installed an app called "Load Monitor" and enabled Wake Lock in preferences. This should prevent the phone from going into deep sleep, apparantly.
Some portugal carrier had a problem with lte sim card or something like that.
I really don't see how a sim card can actually mess with a phone.
Maybe the enabling of some features screws it up.

In my case Samsung Service Team replaced the motherboard. My new MB has a Samsung Electronics wifi chipset. Two weeks now and no SoD.
That sounds good. However, ever since I have installed Load Monitor my phone runs fine. It drains approximately 40% of my entire battery, but it lasts easily until the end of the day.
But again, I shouldn't get too excited. Sim-card change seemed to work in the first few days as well.
Will be continued...
It has been over a week since I have installed Load Monitor. My phone hasn't shut down once. Problem appears to be solved! I hope more people will read this topic, because I have seen a lot of desperate people during my search to a solution.
The only disadvantage is the battery usage of the application. I now have approximately 40-50% at the end of the day instead of 60-70%.

[Q] Help LG-P760 frequent crash

LG-P760 stock Android 4.1.2
Only basic apps, FB, gmail etc.
1. Factory/hard reset
2. Works around 3-4 days perfectly, then starts to crash.
By crash I mean black screen, nothing helps, only battery pull.
3. After first crash, starts crashing more frequently. Happens only in standby.
Worst was today: If I start phone, log in, then it wont crash before I put it in standby. First time in standby, within 30 second, it had crashed.
twice crashed when someone tried to call me. Vibrated once, then crashed.
I would like to avoid replacing my phone.
Any ideas how to find the source of this problem? Any recommendations?

I had the same problem with Vietnam Rom and it was the baseband. I changed to the baseband from ICS from a Rom of my country so I have Vietnam Rom+Original ICS baseband and everything works well.
Thanks.
Although, I understand it mostly is problem when you have unlocked bootloader.
I am running stock everything.
And they have problem with rebooting phone, mine crashes and freezes.
Weird is that it starts around third day of normal use.
I think I have to take on a quest with a warranty. Does anyone know, can I contact LG straight without the provider, where I bought the phone?

I haven't unlocked it. The problem was the same: SOD sleep of death, when the screen goes off you can't do anything but pull the battery.
But if you can use the warranty use it. You should find the warranty info in the box to know where send it in your city.

Thanks. I will search into it. Sleep of death is new expression for me.
I only have phone, it came from relatives who threw away receipt + box.
Luckily I managed to get new receipt from provider yesterday (I dont think they usually give out receipts twice), so now I can use local warranty.
Thanks everyone for replying. I will post update when I have final solution.
Since you are stock you might want to consider flashing the kdz to see if that helps. Good luck!

I'm having the exact same issue with mine. I've heard everything from "try a different SD card" to "factory reset," and nothing seems to permanently fix the issue. What I've found kind of sort of works is just reboot it a whole bunch until it finally comes up and doesn't do it any more. From there, I'm good to go until the battery runs out or I need to reboot it because all the bloatware is causing it to glitch. This usually means that I have to reboot my device 10+ times in a row every few days. Hopefully, you found a more viable fix than this.

Hi
I managed to kind of solve this issue. Because I am not sure how, I haven't closed thread yet.
Anyway, I warranted device, they re-installed soft. Came back, same thing. After around weeks use, SOD. Factory reset. After that, things went interesting.
I tried not to leave it idle. Always had something running. I also had noticed by the time it never occurred when it was plugged in or music was playing.
One day it did it again, but I was in a hurry and just disregarded it. I did something(I was busy, maybe just plugged it in automatically?) and it came back up. It took like 10 sec for screen to start, but it did just wake up. And it haven't had crash ever since. I have no idea is this solution or is this just some coincidence and I am not keen to factory reset again, to see will it reoccur. It's my only phone
TLDR: Managed to get out of sleep of death, haven't reoccurred since.

Need advice with a new device

So I recently got my old bricked evolte replaced by Sprint. The one I was given worked fine the entire time the device was powered on. However, once turned off and back on, its screen would not work. It stayed like this for hours, until I finally started playing with it and realized it would come back on after playing with it for a little bit. I also found out that with this error the home screen pops up for a second when powering on your device, and that's exactly what I had. I read up on the error and found out it was a software error, and to reset to factory settings. So, this fixed it, I thought.
So now, after it is apparently fixed, it still does this to some extent. It will do this if the phone has been powered on for a while, and the screen won't stay off for more than like 2 or 3 minutes. Also the home screen doesn't pop up any more like it used to with the other error.
So what should I do? I was thinking of going to Sprint, but my problem is hardly reproducible. It only happens when it's been powered on for a long time, and won't do it twice in a quick succession. I feel that even if I could show them the problem, they might think they've fixed it when they haven't because it won't do it twice. I would like to root my device, but I'm afraid they're going to say that I'm the cause of the problem if I do that. If it's just a software problem though, maybe flashing a custom rom would fix the problem.
What do you guys think? What do you think is the best course of action? Any advice would be greatly appreciated. Thank you.
Never mind, I didn't know Sprint would order you a new phone if it was a minor problem like that. I thought they would only repair yours. So feel free to close this thread.
