Hi, I've had my SGS2 for around 3 weeks now, and in that period I have had 2 random shut downs.
The first time it happened I was using the original firmware out of the box. The second time it happened (yesterday) I was using the latest firmware via Kies.
The phone is unlocked and unbranded from buymobilephones.net (UK), and I'm on the T-Mobile UK network.
The phone is NOT rooted and I am not overclocking.
Is my phone faulty or is this a software problem? Baring in mind this has only happened twice in the past 3 weeks.
backup data and factory reset would be my first step.
Followed by a return to the store .

Cheers, just did a factory reset. Should I ring Samsung to fix the phone (comes with 12 month warranty) or return it to the online retailer? Not sure what to do.
Just send it off to sammy

... 2 shut downs in 3 weeks?
It's not faulty.
Your contract is with the retailer not Samsung .
I would see if phone restarts again before returning it .
But would inform the retailer of the problem to be within 28 days .

I've owned several phones over the past 15 years and I've never had such problems before, even with my previous Android the Orange San Francisco. Seriously, if I have a £500 phone I don't expect it to shut down randomly even it it's only twice in 3 weeks. I've missed some important calls and texts because my phone has shut down without me knowing.

I think you mean two weeks ago.....
If it continues, you may have a faulty one.
Well I have the same issue, it's in my pocket, next thing when I push the power button the screen just stays black.
Have to hold down the power button to drop it and then restart it.
Sooo, I had this happen once when it was on the table which took the phone in my pocket out the mix.
In the end I tried the battery fix with some geckostrip (that rubber easy removable strip you use on the back of phones to stop them sliding)
I put the strip on the underside (opposite of the connections) and wrapped it around the back (facing the cover).
This makes for a VERY tight snug fit in the unit.
It has now been 2 weeks without one single shutdown...so as much as I thought "this must be software or hardware related", it looks like it very well may be "hardware related" on the battery front.
For those who still have this issue try what I did and let us know your findings.
Cheers
Sheldon
Update: Okay never mind on the battery thing, phone lasted 2 weeks but just blacked out again.....
I had the same problem for many months but it stopped after I uninstallrd dolphin hd browser. No idea if coincidence or not but read a few others with sgs2 and dolphin installed had same problem. Do you by chance have it installed?

I've actually experienced problems similar to this twice now with my SII.
First time was straight out of the box. I charged it up and then took it travelling with me. I kept taking it out of my pocket to find out it had turned off. I thought it was my fault with the power button being in a bit of a silly place. But then it turned off whilst it was lying on my desk or in my hand whilst I was using it. Whenever it turned back on again the battery usage history showed a big sudden drop (10+%) in battery level and then it would increase slowly for a while after. Spoke to O2-UK and they got me to do a software reset and then a hardware reset when it reoccurred, which didn't fix the problem either. They then did a next day replacement.
After I got the most recent update to TW I started to experience times when I'd come to unlock my phone but the screen would stay black. It would, however, give haptic feedback when I pressed the power button but not respond to touch. I recently did a software reset of my phone due to another problem (it kept thinking it was docking this time - but stopped on the day I took it into the O2 Shop) and haven't experienced this since.
For so expensive device I expect only 2 "legal" reasons to shut down while running stock ROM with no additional software or changed hardware (i.e. battery):
1. Battery went completly empty (or as empty as power saving settings allow)
2. I forced it to shut down via power button
If it shuts down on its own under this conditions, first doubt is faulty hardware.
And then it should be quickly replaced by provider/shop/wherever it came from.
Everything else might raise doubt in faulty piece of additional software.
Have had similar issues. Uninstalled the go weather app / widget and nothing since. Might just be a coincidence though.

So I've read about this "sleep of death" that sounds like the same thing as what this is.
It appears to affect a wide margin of Samsung devices over time.
One post suggested it was because WIFI activates while the screen is off and the device is in sleep mode, thus blaming the like of apps such as Juice Defender and WIFI managment built into gingerbread.
I have uninstalled gingerbread, enabled watchdog to monitor utilization (out of curiosity) and set the WIFI sleep mode to NEVER.
One day down without a issue, I'll see what happens over the next few weeks.

I heard that frequent shutdown/reboots happens with 2.3.6 release.
If you got it, better go back to 2.3.5 or earlier. Iit worked for me.
I have 2.3.4 and i get these problems once a month or so.
Wy OH has the same firmware but she gets a random shutdown once a week. We both have the 1900 Anker battery (not stock one) - weird. I am going to try a different ROm and see if it makes a difference.
same issue but after i have deleted à few apps the issue was gone...?

guys im having the same issue too. its happened like 2 times in a month now. it previously happened when i was on 2.3.3 and stock ROM.
today it just happenned again even after being on superatmos 2.1, on 2.3.6.
whats going on?
Just trying to build some statistics as to how common this turning off problem is.
--------------------
PLEASE READ THIS BEFORE ANSWERING:
1) Obviously this is regarding the phone turning off on its own when its not due an empty battery.
2) Only answer with "no" if you've been using the phone for at least a week. If you've been using it for less and it hasnt turned off, answer with "No - but had it for less than a week".
--------------------
I just want to know before I send my phone to Amazon for replacement.
I've had it 8 days, so I clicked the 2nd "no". If I saw any hardware fault in a new device I'd immediately get onto the supplier for a replacement. Unless there's software at fault here (unlikely, but obviously possible) then I can't see the problem simply going away.
Hope you get it sorted mate.
Nope. Had the phone since may 6.

No. Never unless the battrey is empty.

Touchwood, never and I've had the phone a few weeks now.
Had this problem last year with my new Desire, but returned it to HTC and they replaced the mobo without any problems.
Yep had it nearly 4 weeks and its went twice. Not in the last week or so though.

Everyone runs different apps and settings on their phones. Unless there's a specific hardware problem there's going be tons of variables to consider for those having reboot issues. I've had mine for six weeks and its never done anything wonky.
I returned my 1st one as it turned off a few times a day. Replacement has been fine.

Does reboot count as a yes?
I clicked yes but I am not 100% sure if this happened to me or not. Allow me to explain...
I was carrying it in my hand walking and I happened to look at the screen and it was showing the Samsung GT-i9100 splash screen seemingly for no apparent reason. When it went away it just went right back to where it was (no media card reading or anything).
It was strange to say the least but I have not seen it happen again since then and that was about a week ago and I have had the device for approx. 3 weeks now.
Does this sound like the same issue?

Oh sorry i forgot to mention this. No, reboots don't count as they're probably a software problem which can be fixed maybe with a new ROM or update or wtvr (i'm probably going to install another ROM eventually). And i'm not sure how a replacement will help with that, since I already have the KE7 firmware installed.
Just complete turn offs, cuz it might be a hardware problem, which can be solved by a replacement.
Thanks for the responses guys. Keep it up
Hmm, well i'm not really sure of anything, but that looks like a reboot to me. It might be that it turned off and you accidentally held the power button and turned it on, but since there was no card reading or anything, i think it's the "fast reboot" problem i've seen some people with on the forums. I hope it doesn't happen again
My phone started to show erratic touchscreen behavior. A lot of times, it makes it look like something is touching it slightly above back button.
Sense zooms out when I touch the screen, email goes "back" and a lot of times, impossible to unlock it. Reflashed back to stock, same thing. Works fine for 5-10 minutes and then starts these issues again.
Any tips on what I can do?
Its a frequent problem with a lot of handsets, try a different kernel besides the stock one. I returned mine because of that, and the replacement had the same problem
Some of the cooked kernels eliminated the issue.
Wife had the same problem returned it and new phone is fine

This may sound stupid but make sure your screen is clean if it gets to funky it confuses the multi touch
Sent from my PG86100 using xda premium
Screen is clean. Made sure of it. I guess I will take it to Sprint store tomorrow and hope I won't get 1.50 hboot replacement.
Same thing here, started yesterday. No matter what ROM I put on the phone. RUU back and back to S-ON, same thing happening. That was last night, now today I am ready to take to Sprint and I can't get it mess up now! Phone was pretty much useless last night, and fine today, frustrating! As soon as it screws up I am heading back to Sprint with my S-ON self for a replacement!
This happened to me 2 days ago, I tried everything. My problem started when I dropped my phone with a tpu case. Nothing happened and I thought I was in the clear but my touchscreen stopped responding in the center of my screen. It was if the screen had a contact always being touched. I was going to put it up on xda but when i got to the sprint store they exchanged it no questions asked. For reference I downloaded touch test and multitouch test and showed them at the sprint store. The person at the repair center did say he saw about 10 EVO 3d with this problem. I thought I was going to be SOL
I just got back from the service center, my S3 shut off and not turned on. They replaced the motherboard and told me that this happened a lot with other s3 too, maybe that's why they could fix it right away. I'm using stock ROM ,also.
Anyone here on XDA got their S3 to brick itself? What do you think caused this?
Yep, mine did the same a few weeks ago, quite a few others here have had that issue too. I think in all cases the motherboard was replaced.
Edit: no idea as to what caused it. I've always (well since my first mobile in 1998) left my phones to charge overnight and did the same with the S3 when i got it 4 months ago, however I no longer do that now that it's back with a shiny new motherboard *just in case* that had something to do with it committing suicide. There's no reason why that should cause it to die but...

That's very strange, but considering the amount of S3s sold, I suppose a few will go wrong.
Would be interested to know what causes it, whether it's hardware or software related.

In so huge production rate, I'd be surprised if such would NOT happened.
for me, as for now, 2 of 2 works perfectly... fingers crossed, never say never.
For me, what is good from OP's story: it can happen, but samsung reacts appropriately.
i can also confirm that this has happened.
I & others (on this forum) have rooted our phones (and even people running stock OS). After a while (mine was 2weeks from getting it from the store) nothing would fix it. I couldn't even get into recovery mode.
Replaced PBX (mobo) and your good
Dont worry about it, happens to everyone.
edit: should also mention that the replacement via warranty didnt cost a thing.
it just happened to me, and i have no idea about where to take it in San antonio tx, I´m from mexico so no clue
Yet another problem with my device: random reboots. No matter what I'm doing, lots of apps open or only one, battery high or low: the screen goes black, the red LED blinks a few times and off the device goes. Any other people experiencing the same?
You most certainly have a faulty unit.
It happened once. I got the phone on Tuesday. I was reading on Flipboard. Let's see how it goes.

it happened to me too, it was within 7 days period so i exchanged it for another one, the new one has been problem free
one of my friend also had random rebooting problem on her z3c and she sent it in twice for repair without success, if i didn't hear her case i wouldn't have demanded an exchange
Happened to me too, listening to music with my headphones, I pause the music to talk to someone, 5 minutes later press the headphones button to play, nothing happens and when I check the phone it was rebooting. Hasn't happened again yet, was 7 days ago
My phone has rebooted maybe 5 times in two weeks. Usually phone has been idling on table.

Seeing all responses here, it doesn't look very promising... I dont want to send it back yet, because the "service and repair" here in NL is a joke. They do a factory reset, say everything is fixed and send it back to you. I've experienced this before several times with my Z3c...
Hope a sofware update gets rid of these blackouts and bugs.
I got zero reboots after 1 week so i wanted to let you know because its to easy to get negative things out while the people with no problems dont come to the web because they have no reason yet
I had this problem, I fixed it by flashing latest build from xperifirm, and
I also had noticed media storage app using 1gb of memory so I forced close n cleared data and problem has gone.

that's exactly what they did for my friend's z3c, they kept believing it was a simple software problem, you gotta be tough to get more
like the other guy said, my first z5c would reboot just sitting on the table doing nothing, i suspect this might be more than software
Ill repeat, mine does not reboot for itself, and if would be, its an obvious sign 1) you did something what the device doesnt like, 2) you clearly have a faulty unit. Peace of cake, nothing to worry about, just exchange it and voila.
I've been having this problem on my brand new Z5 as well. I bought it from Clove so I really don't want to have to send it back. Gonna try and see if I can narrow down the cause or try to see how I could fix it (factory reset, reflashing the stock firmware or whatever).
Really hope it clears up.
Edit: So I repaired via PC Companion and I don't want to speak too soon but it looks like it's all good. The first time it happened was after installing a bunch of apps, including some older ones as well as some obscure ones. It's entirely possible that one of those apps were at fault. I've tried my hardest to replicate the issue since the repair (and being much more conservative with the apps that I've installed) and I haven't seen it happen once. I'm definitely hopeful now that it was an app-related issue and not a hardware one.

Just out of curiousity..
What color is your device and from where did you purchase it?
Ive been hearing about faulty white Z5Cs which Sony acknowledged even.
Mine is black. But I have only had one spontaneous reboot the second day after I bought it. 3 weeks now and it hasn't happened again.
Sent from my E5823 using XDA Free mobile app
Mine is black color.
I have it since 4 days, and it already rebooted three times randomly ...
I don't know if I'll keep this phone or resend back and have an other brand device.
It happened with my white one when I had my SD card plugged in. I sent it back and got a new one
Mine's black and it never rebooted on its own
Black Z5C. I've been getting that kind of reboot regardless of repairing via PC Companion, or build number.
Any thoughts on what might be the issue?
Also, off topic, I believe I have two dead pixels (installed Screen test, and two pixels can't reproduce blue color) and I was wondering if that was an issue that might get me a new phone or just repair (it's been 2 months since I got it)?
I've had it for a month and maybe have gotten one or two reboots. I recently took a week long vacation and got 4 or 5 freeze/reboots. I'd be viewing photos, taking a picture, recording 4k and it would freeze. Power button could still bring up the menu but screen is not responsive. Eventually it reboots with the red led flashing. Only one it just rebooted with no warning
I have between 0 to 3 restarts/day. Sometime it crashes and freezes in the crash without restart. That is very nasty. I'll try to track it down.
