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...?

Moving to Q&A
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?
This weekend I upgraded to the Photon 4G for $99 at Best Buy (gotta love Labour day weekend offers).
I'm moving from an HTC Evo 4G. The first problem is the worst. Since picking up the Photon 4G I have had to pull the battery 5 times as the phone refuses to wake... With the HTC if I had an issue I could reboot by holding down the power and volume button, but the Photon doesn't seem to have this feature, so I'm forced to remove the back cover and pull the battery...
I don't seem to be able to re-create the issue. Its just happens without notice... Anyone else having this issue? Is their an easier way to coax the phone back to life rather than pulling the battery?
The second issue is the screen. Every single review I have read has said that the screen is a Photon 4G strong point... I'm not convinced... Yes it is bright and vivid, but I seem to have an annoying grey criss cross pattern all over the screen. I'm not sure if its my eye's (the GF says she can see it too) but I was expecting the screen to look better than both my EVO and Xoom... This annoying grey criss cross gauze (especially visible on white backgrounds) is disappointing..
What do others think? Colour gradients also appear to band very easily, rather than being smooth.. I'm not sure if this is a result of compression in pictures tho...
Other than that, I am happy with the phone. Big improvement over the EVO 4G i had befor, just a screen I have to get used too, and this un-responsive issue to fix...
Oh, and having to get used to Motorola's Android button layout and Standard Android icon changes is a little painful at times...
Swap out for new one for wake problem. Turn brightness down to 30 percent and screen is fine. Had all top HTC phones and this beats all.....keep this phone....

I get that sometimes, but fail to replicate at the store. Store employees will only recommend to wipe the phone.
The pentiles pixelation is only noticeable when your face is extremely close to screen. Its a cell phone not a tv display lol, stop holding it so close and you'll be fine! Im on my first phone with no issues yet; just to be on the safe side i would swap for a new device.

Actually, the sale has been going on for close to 3 weeks now. Sorry you are having issues, have you tried a factory reset then not install any apps (or not many) for a couple days to see if it was one of them?
An opinion......
I try to avoid the Sprint stores as much as possible. There are some knowledgeable reps out there but it is a small percentage. Most of them don't know much about the devices. Call the Sprint support number first and try troubleshooting with them. In my experience, they are better at going the distance to make the customer happy than the peeps in the stores especially if you keep on them about it.
Sounds like a swap out is needed. Good luck.
Go back to BB and try to swap it out for another one. Had my photon for about 3 weeks now and never had this issue
I have to agree it sounds like a hardware issue and merits a swap. I've had the photon 2 1/2 weeks and have only had to pull the battery once.
Mine has been freezing and needing a battery pull every day. I went through Sprint VIA phone and they sent me to the store. The Technician actually researched it and it is a know software issue that will be fixed when the next OTA software update is released. I went from the silent call issues to my phone turning off/freezing and I don't even know that its not working. Not happy at all right now
I've just got back from Best buy after my phone refused to wake up again for the second time today.... I let them try and get it turned back on again which they couldn't do without pulling the battery... Either way they immediately confirmed they'd swap it out. Until she went to pull one and realised they are all out
My replacement arrives Friday when they get restocked.... Best Buy must have sold loads since Friday because their shelf was piled pretty high when i picked mine up...
So hopefully the new one will work properly, or maybe I'm just plagued until the next OTA...
As to everyone who gave me suggestions about the screen... you were right. Turning down the screen brightness pretty much solved the issue all together and I think I am officially used to it now...
Just wish i could get my EVO 3D ringtone , Alarm and notifications on the Motorola. I grew more attached to them, than I thought

OK, I did not think that it could be my SD card causing the issues with the phone freezing up and needing a battery pull to get it back on but the Technician asked me if it was a new card or from another phone. I said It was from two or three phones ago. They said that I should format the card because the files from the older phones can cause problems such as this, after copying my photos over to the computer to be able to put back on the card afterwards of course. They had left my SD card out of the phone. So to test things, I haven't put my SD card back in since two days ago. My phone has not restarted or frozen up once. I will give it some more time and report back, but in the mean time, until there is an OTA fix, if you are using an SD card from another (previous) phone, and your having the freezing/power down/restart issues, you may want to give formatting your SD card or removing it to test if it fixes the problem a shot. Good luck, so far so good.
I've not used an SD card at all since purchasing my Photon. On the Plus side, it has not stopped working at all so far today
Had the same problem when I bought my 2nd photon this time at best buy becuase of the $99 deal.
On the 1st one i got directly from a sprint corp store, no issues at all. But this one on the 1st day I got a reboot issue. second day got the SOD. went in they had some trouble getting it on. Had to tell them to take the batt out and it went on. My problem was that they had none available. so for 3 days I waited.
Funny thig is that I wasn't getting the SOD again. Just didn't want to chance it so got another one, yesterday. Happy today.
There were no motorola photon availble in my area. So they are selling.
Good luck with yours.
OK it's not the sd card causing the issues. It's back to freezing up 1-9 times per day and then I need to do a battery pull and restart the phone. Motorola wants the phone back to repair it. This should be a great Two weeks and if the phone is not fixed, I will lose it........ For sure

Ok, if this information is correct from Sprint, I know why I am having all these problems with mine freezing up and after having done several hard resets and many calls to Sprint and a visit to the service center with no fix. Apparently there was a batch of Photons that got shipped with corrupt firmware. When the phone uses that portion of the firmware, as a safe mode, it freezes. There is no fix other than replacement with a non effected phone. They ordered me a new one, that I will get on Tuesday. The only way they can correct it until there is an OTA patch is to send it back to Motorola. Wish me luck with this one
Update....
So here is the update....
5 Days of Ownership - A total of 9 shutdowns of the phone with the only way to get it turned back on again was by pulling the battery. On the 9th time, I went directly to Best Buy to show them. They agreed without question to replace it. Unfortunately they had sold out so I had to wait 2 more days for the next shipment. Gotta say Best Buy were excellent tho. I had 1 further shutdown before getting my brand new replacement.
3 Days of brand new replacement Photon 4G ownership - I am disappointed to say that I have had 1 shutdown so far and this was on the second day. Not sure if I want to Jinx myself but the shutdown rate is lower in the first 3 days than it was with my original.
But it's looking more and more like it's a bug in software than hardware. Either that or I get the DUD from two completely separate batches of phones.

Well, I got my brand new replacement yesterday at the Milton Massachusetts Sprint Repair Center and as of yet no shut-down, or freeze-ups. I have my fingers crossed here on this one. If not I will be reprogramming another new one soon. They did assure me that this is not affecting every Photon, but there was a large batch released with this corrupt firmware. Its like a waiting game to see if its a dud or not. I do love this phone, and I am getting tired of setting up these phones over and over again, but on a good note, I can completely customize my phone and all my apps in about thirty minutes from activation
So, a few weeks back my Mozart started presenting problems... In it's defence, i've had that device for approx. 2 years and if you see the state it is in right now, you'd be surprised it survived this long!
Now I love Windows Phone and my next device would have been Windows Phone 8 but alas, I need a stable phone with me always and thus can't rely on the Mozart in its current state. So I sold off my iPad 2 and went ahead and bought a HTC One X and initially loved it but grew to dislike it... mainly due to random crashes (probably a device manufacturing defect) but most importantly due to the poor battery life.
So I sold off the One X and purchased a iPhone 4S however after a few days of usage, some microphone issues emerged. I got it replaced and soon enough, the issues surfaced on the new device. Checked online and a huge number of users are apparently facing issues with iPhone 4s as well... so then returned that and got a iPhone 4...
But alas! Websites on Safari were a pain at times, cellular data would kill itself during a call though it didn't happen always, and some other stuff as well... So now i've sold it off and am in the market for a new phone.
Today i returned my cousin's HTC One X and got a Galaxy S3... have been testing it out and am loving it so far... Especially the battery! Charged it up to 67%... have had Exchange Sync (Push) turned on, two Gmail accounts on 15 minutes sync, Facebook and twitter push, and made at-least over a dozen calls some of them going over 10-15 minutes... and a game here or there plus an hour at the gym with continuous music playback and referring to a workout app... and in 3 hours time, it's battery has gone from 67% to 49%!!!
If it were my One X, it would have pretty much died by now or come close to it. Even the iPhone 4 didn't produce such good battery results for me - but close nonetheless.
So now i'm considering to the store tomorrow and purchasing a S3 for myself! Wanted to see if anyone here could provide any feedback on usage based on a couple of weeks or days of usage of the device? Battery life? any crashes? Anything else?
UPDATE
Forgot to ask another important question... Now forgive my ignorance, but I am kind of new to Android - although I did use XDA numerous times to flash my brother's X10 + Arc and Sis-in-law's HTC Chacha... when i purchased this phone today for my cousin, it was a packed box. On opening and starting it up, it asked for a PIN code to activate. Which i Imagine meant that it was carrier locked?
The shop owner disappeared for 10 minutes and returned back with the phone unlocked and ready to use. He said he got it unlocked by using a proper code and all... and to be on the safe side, as soon as i got home, i did a hard reset and it didn't lock out on me. However, I do notice "ClockworkMod" installed on the S3 and also the state of the device in settings is set to Modified. What does this mean? Any cause for concern?
Regards!

The shop owner probably rooted your device in order to unlock the phone (rooting voids your warranty), do you see a superuser app in the app drawer?
If so, install Triangle Away from the playstore or Chainfires thread here http://forum.xda-developers.com/showthread.php?t=1494114 and reset the flashcounter. Than go back to the shop and let him reflash the rom to restore warranty.

If its just warranty... then not worried about that. As i purchased this one for my cousin without the warranty - Rs. 5000 cheaper (approx. $50).
But thanks though, this is good to know... 'coz I was planning on purchasing mine with the warranty!
Battery life is a lot better than the one x..... the s3 should easily be able to get you through a day of heavy use and have juice to spare.

Hello:
So, the bottom line up front is I need help solving a problem with my now third, new Verizon Samsung Galaxy S4--it keeps restarting on its own, at random times, but most often after I lock the screen.
To go in more depth, if you think you may know the solution: I purchased the S4 when it first came out, some time in 2013 (not sure specifically, but it was new) and it worked just fine for 13 months (1 month past the warranty of course); this was back in August, when I got the latest Android update pushed to my phone from Verizon (4.4.2). A couple of weeks later, I would occasionally get overheating warnings that would very quickly disappear (like within a few seconds), and then the device started restarting itself... I cannot predict when it will restart, it's random, but like I said above, it usually happens most right after I lock the screen by pressing the right side button once. I started looking around on the internet for a solution then, but only found a couple of videos from earlier in 2013 where people were having battery problems (Google search has been letting me down more and more as the years pass). One day while at work, I was listening to Pandora as I always have with the phone in my front pocket, as I always have. A few hours later when I got home, not having taken the phone out of my front pocket since those last few hours at work, I went to answer a text message I had received; when I unlocked the phone, the screen was black, except for a small bit of white showing through some cracks UNDER the LCD, UNDER the screen protector, INSIDE my Otterbox Defender... the phone appeared to be working still, but the screen and touch screen did not. At that point I was pretty damn irritated and tried to find answers for a week with no luck... I called Verizon, they sent me on a goose chase to Samsung, who sent me back to Verizon, who got me in a conference call with Samsung and then left the call, and then Samsung ultimately said I would need to pay for repairs to the phone... SO... I went back to Verizon who again said I would have to talk to Samsung, but instead I just settled to giving Asurion (my phone insurance through Verizon, whom I pay an extra $9 monthly) $99 as a deductible to get a replacement S4...
Two days later I receive a brand new S4... spend hours setting it up the way I had my prior one... wasting tons of my valueable time to do so and bandwidth from my Concast ISP and the data cap they've decided to give us... one week later, the phone starts restarting itself... and this one did it more often than my prior one... EVERYTHING is up to date, minus a good amount of useless bloatware apps I never use from Samsung, like "Watch On," which I ignore... but everything necessary, I update. So, I go back to Asurion, who quickly ships me a 3rd S4...
Two days later I receive that third, brand new S4... spend hours setting it up the way I had my prior one... and now, this one is also restarting itself randomly. Interestingly, when I visited family for Thanksgiving, it restarted itself over and over and over much more frequently than when I'm at my place... at my family's place, they have very poor reception, and my phone usually has to work more to try to get the signal... IDK what the deal is, but maybe that information can be helpful to y'all.
Other things to note:
1) When I check the "RAM manager" by holding down the home button and then choosing "Task Manager", the phone is always using at least 800MB of 1.77GB of RAM... even when I choose "Clear memory" and it tells me 30 something apps have been closed... it jumps right back up to 800-900MB of usage.
2) I've tried factory resets on all three phones; with the first one where the screen cracked inside, I hooked the phone up via HDMI... within a couple of days, the restarting begins.
3) With the first replacement I received, I could not sent text messages with the default messenger app... and shortly after trying, it would restart.
4) I have used the same SIM card with all three phones since the issue began, when I first got the 4.2.2 update... I do not suspect the SIM card is the problem, but I'm also not savy with the phone... I know my way around it, but I'm not in the know.
5) I thought maybe it started because of some apps I had been trying, so I had deleted them, and the problem still persists.
6) I constantly have a Pebble Bluetooth smart watch connected to the phone... I have since I got it last Spring (2014).
7) I have never rooted the S4, overclocked it, underclocked it, or modded it in anyway because I do not know how, and I was afraid of what could happen in the future with whatever ROM I did flash onto the device if Verizon tried to push an update to it... I just don't know anything about the whole process, and I'm assuming it requires a lot of know how and babysitting of the device... I just want it to work.
8) I've replaced the battery twice; it doesn't seem to be the problem.
9) I've cleared the cache through the boot manager thing gotten to by holding a combo of buttons on the device while it's rebooting... it did not help.
Edit: 10) Today while I was listening to Pandora in the car, the audio began to skip and scratch, and then it paused for a moment, and then the phone restarted itself.
11) I forgot to mention that the reboot process itself is very fast compared to a manual restart performed by me... the phone will go black, the Samsung color rings will show a second after that, the logo appears then, the screen flashes the red Verizon logo, and then the devices is ready to be used... it's less than 10 seconds.
I've been searching around on the internet for about two months now while dealing with the problem and I can't find anything useful. Does anyone here know what my issue is and how I can fix it? Is there a way to pull error logs / information from the S4 somehow to give to someone to diagnose, like DxDiags on PC? I don't know how to read that stuff myself, but I know it can be very useful... I just don't know how to find that info inside of these very locked down ****boxes we call smartphones...
I truly appreciate any help I can get--sorry I can't offer anything in return; if I can't find a solution, I'm just going to go to my backup phone from 2011 (Droid X), and I will definitely never purchase another Samsung device, especially after they blamed me as the cause of the problem without even seeing the phone...
Thanks.
The problem is with the NG6 software build, and "probably" not with your phone. Go to Settings>About Phone> and see what Baseband Version is on your phone. If the last 3 letters are NG6, that's probably the problem. There is a new OTA update (as of 12/1).....Baseband Version ending in NK1, which corrects the rebooting problem. Either install the new update, or go back to the NC5 baseband version and that should solve your problem. Both NK1 and NC5 can be rooted if you desire.
A few days ago we purchased a couple of Samsung GalaxyTab A 9.7. For some reason that I haven't been able to work out two of them will reboot every now and then, there is no pattern to it, it could take a day or two and then it will reboot while reading a book. Or another example I decided to do a factory reset of the tablet to see if it was the kindle app or the SD card I put in it, so with nothing in it after doing a factory reset and while updating the preinstalled Galaxy Apps it once again restarted. Just wondering if this is an issue with the tablet or just the buggy android 5.0.2 it is running.
I've had one for a couple weeks now with the same restarting issue. I've hard reset and cleared cache at the recovery menu with no luck. Hoping it's a 5.0.2 bug, because I bought for use while instructing.
We have three, one of them isn't doing it. We took one into the shop, did a factory reset so they could send it back to samsung. The stupid assistant manager had a look at it and said oh the sleep is set to 3 seconds, he set it to 30 minutes then said it was fixed, he couldn't comprehend it was set at that because it had been factory reset to send up to samsung. Then we came home, let it rip to Samsung and they wanted both sent back. According to the samsung rep they haven't heard of this happening with this tablet.
Thought I would update this thread. The shop rang today and decided that they wouldn't wait on Samsung so replaced both tablets that were having this problem. Got home, charged the first replacement tablet, then set it up, as soon as it gets past the set up it reboots. then basically within a period of 10 minutes it reboots 5 times. Second replacement tablet so far seems alright. Samsung want the replacement tablet sent to them, so my advice dgr00s is get in touch with them and get a replacement.
So, i've been troubleshooting and whatnot. I used Samsung SmartSwitch and initialized the tablet. I used it all day at work without issue, today. Could be coincidence, but I will let you know if the reboots return.
Sorry for your bad luck. You could try the initialize with SmartSwitch to see if it resolves your issue.
according to samsung it was a fault with the tablets. all faulty tablets were returned and replaced all is good now, samsung have three faulty tablets to mess around with
