[Q]My s2 powered off it self - Galaxy S II Q&A, Help & Troubleshooting

the phone powered off it self until i pressed the power button to turn on again. i noticed this often happened when i put in my pocket for a while. but when i put it on table over night it didn't happen.
roms that i tried that had the same problem:
batista 3.7++
lightening 3+,6+
cognition 1.4+
apps that i tried uninstalled but no avail:
-setcpu
-daemon control(batista rom)
-juice defender
is it due to motherboard issue? appreciate your advice. thanks.

have u tired wiping data and dalvik cache before installing any rom?

thanks, yes, i in fact wiped all and even install stock rom before any mod roms. and i also changed few kernels(stock, nipo, CF..)but still the same..
now trying to use kh4 stock rom and see..

So the this issue s only occurring when the phone is in your pocket and never when out of your pocket.

this happens to my Phone as well.. its kinda random...
sometimes when am listening to music and sometimes when its just on standby
for example it just restarted which reminded me to search for this error...
few days ago it was on standby and had shut itself down and the battery was completely drained after 5 hours without anything on.

yes, found it only happens when putting in my pocket. when charging over night or putting on my work desk, it didn't happen.
and yes, it happened few times when it turned off it self, it lost about 10% to 20% battery in just few minutes... the phone was warm when it happened. that was why i took out to check and found it already powered off..

What firmware you have? I run on XXKH3 for 3 days (previously on XXKG3 for 2 weeks), no boot issues.

lightening 3.2 = KG2
Batista 3.7 = KH3
Cognition 1.4 = KG6
all happened to shut down it self. so i guess it is not rom issue..

I would try a stock ROM for a week, just to be safe (no apps/tweaks/kernel, etc., really stock). I'm pretty sure a recent stock ROM will not give you issues, I would not worry about the hardware.

thanks for your advice, will try stock rom then

Ya, do that... just to see what is going on.
More on the technical side, the screen needs minimum 500Mhz to get out of Sleep Mode. Some custom Rom's use a low voltage or "underclock" feature that reduces the power consumption but also the number of CPU steps. That is what makes your phone crash and reboot randomly.
Once you put the stock ROM, do a sdcard wipe (if you use one), just to be safe. It should take several hours, so do it over the night. Personally I would not use an external sdcard during the one week test, just be sure.
You could also have a RAM (hardware) issue, ya. But 99% of the time is related to software. Bad memory degrades fast so you will see your random reboots pop at a faster frequency. If you did all the above and still experience random reboots, run adb logcat to see what is going on at that specific moment. If you get error codes like:
Code:
code 1 (SEGV_MAPERR), fault addr 00000000
you are dealing with bad memory unfortunately and need to service your phone.

I also heard that some people had bad battery contacts on their S2. Clean them with some audio head tape cleaner and cotton swabs, than make sure the contacts are proper... it should eliminate this possibility. In a way, it makes sense since you move a lot with your phone in your pocket.

you got my THANK button too. but how to run "adb logcat"?

Is all explained into link. Time to read?
However, I have a feeling this is your problem, since the phone restarts in your pocket only. Don't smack it like the guy did, heh. Go easier, think like it is your girlfriend...
Just clean the battery contacts and make sure they touch properly.

is there a guide on how to install Stock ROM back on? cant find any...

how can i root my sgs2...?

it also happened to my phone. so i brought it back to the store where i purchased it and told them that it was shutting down randomly when i put it in my pocket. after 15 days of waiting i called them for follow up because they told me it will take 7-10 working days. they told me that the phone never shut down in the service center. what can i do about it? i don't know how to flash or root. this is my first android phone.

I have finally found a solution... installed XXKH3 FW stock, not rooted yet, and installed an application from the android market called Load Monitor
Code:
https://market.android.com/details?id=com.landak.loadmon
and enabled only Add Notifications, only notify high load, autostart and only screen on... seems to do the job, no battery drainage and most of all NO SOD (Sleep Of Death) or restarts anymore
If you still have problems try checkin wake lock from the options of the app...
Hope it helps

The phone did not rebooted in their store because they did not move it, you have a bad battery contact that can be fixed easy.

Weird, people reported that app adds load to the phone. Why not use terminal instead to check the stats?

[Q] Galaxy S II doesnt shut down (gets stuck while shutting down,not rebooting)

Hi everyone,
first of all I did search forum, but havent find answer nor related thread, if I have missed it please sorry about it.
Got my SGS2 about 6-7 months ago. No issues, everything perfect. Got updated to 2.3.4 with KIES (not really fan of experimenting with phone that have price of above average monthly salary in Serbia).
Rooted device with ZergRush exploit since I wanted as close to mint backup in case I have to send it to service(dont ask, service here is pain in the butt), purchased Mobile Odin Pro (cheers to that Chainfire) and flashed Hellcat's kernel for 2.3.4 from Mobile Odin.
Everything was cool, CWM, made EFS backup with his tool too, and so on...
However, about 2 moths ago, I started experiencing random restarts of the phone. Did search, found out that it happens and actually dealt with it.
Now, recently, i switched off my phone in the evening (was on 20% and didnt wanted to leave it on charger, and didnt want it to die on me during night), and in the morning I havent been able to turn it on. Freaked out badly, only to realize that its battery was empty. Which was odd because I DID turned it off.
About few days ago, i switched the phone, and it went to full shut down, however managed to get stucked somewhere in process (LED's are on, did vibrate i think) but never shuts down itself.
After some time, when I picked it up since I saw LED's on, i realized that its very hot and that I cant switch it back on (presumably because it never got shuts down) and had to remove battery so that I can switch it back on. When I did, i found out that battery was about 15% drained in that 10 mins, and I dont know what he was computing while shutting down, but it burned the sh*t out of itself.
Tonight it did that again so I decided to ask first before I do factory reset/wipe everything (maybe update to ICS too).
So, any idea, suggestion what to do is more than appreciated.
Cheers
Polite bump?
What is the actual problem .

Well assuming you have read original post, why the hell that happen, does it happen to anyone else, and how to avoid it?
this may help
http://forum.xda-developers.com/showthread.php?t=1108499
Well, as I said, its not bootloop.
As I said, I shut down the phone, it starts shutting down, turn on leds, vibrate and stays turned on. After that battery drains quickly, and phone gets very hot.
When I get battery out, and back in it boots up without problems.
And I dont have any cooked rom, just Hellcats kernel for 2.3.4 stock rom.
you problem
Hi there,
Here's the best way to resolve this issue you have to re-flash a fresh new rom, meaning a full installation of the android os and here is how to do it,
First search google and download ODIN to ur computer or Pc.
Next search again google and type the following ( Sammobile.com ) and register and after that type the model number of your phone for example (i9100) in the site search bar and download rom that u need and thats it this should solve ur problem
Note : be sure to have 100% battery charged before doing the above and after installing ur new rom do a full wipe and enjoy,
I hope this was helpful,
Regards,
iMatrix
Yeah, thats probably that I will end up doing, luckily i have bought Titanium Backup so that I can backup all apps that I have and restore them after wiping everything.
I was wondering that somebody have any idea what might be going on.
Thanks for suggestions everyone.
before that try wiping cache and dalvik cache

This seems to happen quite a bit on gb roms.. definetely time to upgrade to ICS
Actually from what I have read about ICS 4.03, Im actually glad I didnt.
Releasing it in that state(e.g. battery issues again, 3rd party sms programs sends sms twice...) is bad for both G and Samsung imho...

[Q] my.phones issue.

For the last two days my phone has been anything off at random... nothing has been changed... I'm on the cm9 nightly from the two days ago... this is the thing tho... If I gentely tap the phone it will shut off or shake it... so I figured maybe after time the batter is lose... but it also is turning off if it sits completely still...unless its playing music. It has not turned off since Round 8 ad I have just had it playing music this full time ...any ideas??
I already did a full wipe and re install and when I get home I'm going to Oden back to stock and redo everything.

My only suggestion at this point is odin back to stock 2.1.
Unfortunately this sounds like symptoms of hardware failure. I had a phone (cliq) which would do the exact thing as you described...the phone would vibrate shut off and reboot unexpectedly. I would open the physical keyboard and it would also shut off...this is totally hardware related from my understanding. But that is the worst case scenario.
Hopefully it is a software related issue in your case. Not much else i can say.

Overclocked? Voltages changed at all from default? If you have anything set in voltage control or setcpu, get rid of them and try it. You could also try booting into recovery and see if you can reproduce the problem. That should also help determine if it is software or hardware related.
If the phone is plugged in it does not seem to reboot. i have not had time to mess with it i will check it out this weekend. Weird because it only seems to be doing this at work? I have not had it restart on me at all while at home.
Also if i have the music playing it will not turn off. This weekend im going to oden back to stock and see how it goes. otherwise gonna try to deal with it long enough till the gs3 comes out, ha.

SGS3 keeps rebooting randomly

My SGS3 works just fine for 2 weeks, until now.
Suddenly, it keeps randomly crashing and reboot into samsung s3 logo screen.
Oh, I have tried different roms (and stock rom also) but the crash still happen.
I also have tried wiping cache, dalvik, clean install, removing external sdcard, and restore factory setting. But none was effective.
Any ideas?
I had a similar issue with my Atrix and it turned out to be the SIM Card. Had it replaced and no more random reboots. I figured this out by checking the panic dumps...maybe there is a similar way to check this on the SGS3

Thanks for the response.. I tried it just a moment ago without sim card, and it still got the random reboot..
Any other people who got the same problem?
Is the phone unusually warm? The phone will automatically reboot if it overheats, but that wouldn't normally happen unless it's been left in the sun or overclocked.
I can get mine to go into a reboot loop if I play Asphalt 6 while outdoors, but the problem goes away as soon as I let it cool off for a minute or two.

yes, the phone (when i use it) is usually warm, but my phone also crashed while not in warm state.
but this crashing-reboot problem just show up after 2 weeks of normal (and not any crash experience) usage.
this crashing problem show up after i played temple run btw (not sure is relevant)

Sorry to hear that man. Had a SGS with same issues. maybe Samsung has hurried releasing galaxy S3
I'd factory reset and only put on the important apps you use. Depending how long it takes for you to normally get a reboot you can slowly add new apps back to narrow it down. I had the same problem last year and thought I had a bad sgs2. But it turned out to be dolphin hd browser at the time that caused it and haven't had a reboot in a year. It could be something similar in your case. Hopefully its software related and not hardware

i just tried flashing normal ROM, after booting to "get started" page, approximately 3~10 seconds, my sgs just rebooted over and over again, until it show only black screen with battery icon on it (i think it may be charging animation while the phone is turned off).
ahhhh this is driving me insane!!
update : i just flashed hypergalaxy ROM and currently it is stable and not experienced crashing (yet ).
i'll give further report later today

Have you tried reinstalling FW with Odin? If yes does it still reboot after a factory reset with nothing installed?
yes, i have tried flashing stock rom using odin a few hours ago, but the crashing still happen.
my sgs3 now stuck at boot-standby5sec-crash-reboot loop.
so, i decided to bring my sgs3 to samsung service center tomorrow. hope they will replace it with a new unit
UPDATE : Samsung replaced my new SGS3 with a new hardware (not sure new device though, the flash counter reset to zero )
the problem seems to be hardware related
thanks for all your reply to my problem

I am having the same issue, I've had my phone since Saturday (6/23/12) and it crashes, reboots, apps crash, internet crashes, email crashes, etc. I can udnerstand a lot of apps may not be updated to ICS.. but no matter what I do.. everything crashes.. It's a bit ridiculous. I am a prior iPhone 4S user and am probably going to return this phone. I can't do much without it crashing or the screen freezing.. not being able to do anything for 2-3 minutes, etc. And they couldn't port any of my numbers from my prior phone because they didn't have the software update to do so yet. So overall, bad experience with the Galaxy.. and maybe I should have waited longer before buying this phone to work all the problems.

I'm very sorry that u have these problems.but there will always manufacturing faults when making so many units.only one thing to do,return it and get a replacement.when u get a fully functional galaxy u won't regreat it,it's a awesome phone.Samsung usually replaces the phone,so I think they will do the same in your case.anyway best of luck
After all the problem I've been through, finally I send my phone back to samsung service center.. they tried to reinstall stock rom several times, and in the end, they change the IC board to a new one.. and it does solve my probs..
SGS3 tebooting
Hi guys here is a peace of my experience
Bought the phone last year in November .2 weeks everything fine then it starts rebooting itself.retun it to the mobile provider and get it back in 3 weeks with conclusion that they experience the reboots as well and that the phone had some kind of software issue.in 3 hours i was back in the shop with my phone rebooting again.they send it again to service got it back yesterday with 4.1.1 android and they sad it may be caused with wrong customizing or not supported sd card,turned on the phone and had few reboots manage to update to 4.1.2 and today heavy gaming internet etc and no reboots so far.will test it till wendsday and see what happens.if it will reboots again then its going back to service and this time it is the 3 time so i will get a new phone.

[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.
Sent from my LG-P768 using xda app-developers app
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.

My tab s3 keep restarting and freezing by itself

Hello everyone
I have Samsung Tab S3 since it's release in 2017 .. and it was a very nice tab till a couple months ago ..
It started restarting by itself .. and it happenes always when I'm not using it or when I'm pausing a video ..
And when I leave it for a couple hours i find out that it's turned off and it can't be turned on till I hard restart it ..
I tried :
Emptying the battery to the end then recharge and didn't work.
Removing SD card and didn't work.
Entering safe mode and still restarted.
Wipe cash partition didn't work.
Factory reset and didn't work.
And finally flash stock ROM with Odin without rooting .. problem not solved
When I put the tab on power saver the restarting takes so much longer to happen ..
Could it be a hardware related thing? Or a battery thing?
Thank you in advanced for your help
*Edit 1 (problem fixed) : I rooted my tablet and installed Kernel Auditor app and changed the governor to Userspace and set the minimum frequency of the CPU to 422 instead of 307 and made the app do the settings change on boot . After this it had not restarted for 3 days.
*Edit 2 lately I flashed lineageOS unofficial 18.1 android 11 into the tablet and edited the big clusters only to interval governor while keeping the small ones with blue schedule. My tablet now is working like a charm with no issue.
Has the battery SOT time noticeably decreased?
If below 80% of its original capacity it's time to replace it.
Any swelling is a battery failure, replace asap.
Changes in charging behavior could indicate a failure as well.
Has it been dropped or exposed to moisture? You see where this is going... mobos can also randomly fail.
Does it happen in safe mode?
Check it to rule out 3rd party apps.
Original rom, don't update the system apps, all power management should be disabled.
Pull SD card if it has one for now before reload.

Thank you for replying
*After the restarting it gets stuck and shuts down and you have to turn it on by (down+power), if you turn it on immediately you have the same battery percentage but if I let it through the night and force turning it on the battery is decreased alot, it looks like when the tab is off after the freezing and restarting it is consuming alot of battery even if it's off.
*I tried the safe mode it still restarts
*I went to the beach 6 months ago and it stopped charging because of the moisture for about a week then it got back to its normal state
*I noticed that When I boot into (downloading mode) or (recovery mode) it stays on for days and doesn't restart or freeze
If you got salt water in it, it's already dead.
Needs to be pulled apart and inspected for corrosion damage. Sorry...

You mean the motherboard or the battery is dead ?
If the mobo got salt water on it or even water in it can destroy it. Current flow greatly accelerates corrosion.
The tab needs be dissembled*, dried and inspected for damage especially where there's high current flow and exposed conductors.
Sooner is better...
*pull battery connector asap

I had to replace motherboard
My tablet turns off by itself
Good evening. As the title says, my SM-T820 turns off randomly. I've changed the battery and installed several official firmwares with no luck so I don't know what else I could try, if anybody has any idea please tell me. Thank you so much Kind...

Ah thank you, not sure if this is true but if you install a custom rom will you will lose functionality of the s-pen?

You are welcome
it will still work but the button will stop working .. after all you will get a 2017 tablet to work with Android 11 with an amazing speed and without all that bloatware that were slowing the device. And if you didn't like it you can go back to the stock rom whenever you want .

It worked has not crashed yet and I found that s-pen button thing annoying anyway so thanks again for the help
I sometimes find my S3 has shut down and requires a long press of the power button to boot up. I have not determined the cause. I wonder if just root will allow deleting enough bloatware to make a difference
