[Q] S2 suddenly goes off - Galaxy S II Q&A, Help & Troubleshooting

Hi.
I have a GS2 just updated to 4.0.3 but I have the same problem I had with 3.2.x.
I leave the phone with any battery status form 98% to 30%, when I push the home button to wake it up nothing happens. Nothing with volume or power. I have to keep the power button pressed for 10-15 seconds to boot it up.
Any idea about what could be?
Thanks in advance.

had the same problem. It started about half a year ago and went worse and worse, until it happened almost every day.
I sent it to Samsung and they said 'They found and repaired the problem' but it was still there. Then I had the device replaced (by amazon) and since then...everything fine. So it probably was hardware related to a certain extend. I tried killing some apps that could cause it, which seemed to let it happen less often before i replaced it, but it still did happen. Things like tasker and stuff.

Thanks.
I'm afraid you're right and I should bring the phone back to the reseller.

Re-sellers ans techs
I had to take my GS II to the Samsung Techs ans they were very worried about the customer, if the product is working properly etc.
I think it worth the visit.

Serious issue...

Hi there; Could do with some help please I seem to have a series issue with my Samsung Galaxy S2 today. It started this morning; I noticed the screen was randomly turning on; for no reason what so ever. It only does it when the phone isn't charging, if the data cable or the charger is plugged in; it doesn't do it.
Its on version KE7. I have tried a factory reset, and that hasn't sorted the issue. Therefore I seemed to think it was a hardware fault, however with it not being an issue when plugged in I wondered why it might be doing it.
Tap to speak also kept coming up for no apparent reason, I say kept coming up, doesn't happen all the time, but did come up about 6 times today, when I hadn't pressed anything, which would suggest the bottom centre button could be stuck or sticky, however that seems fine; and its not been near any moisture and has been a hot day.
The phone has not ever been rooted; so no issues there.
The phone battery dies very quickly within about 4 hours with the screen turning on all the time; and the phone will randomly freeze up completely, and I have to remove the battery to reset the phone.
Anybody got any ideas? Really could do with some help
Thanks
Rich
Update: It is plugged in charging now; and the MTP Application has come up; like the data cable is plugged in. That seems very odd to me...
Don't be afraid to send it back. These things aren't cheap even if you're paying through your contact, you're entitled to get what you paid for.
Your specific issues may be down to more than one thing. My screen lights up when I've read my gmail on a different device and it needs to clear the notification. Nothing too worrying about that. The other stuff does sound like some sort of shorting though and people have been given replacements for less serious issues.
I'm tempted to get mine swapped because the wifi often won't pick up an IP address and the gps won't get a fix if the phone gets too hot. Relatively minor compared to your issues.

Yeah I think its going to have to, I've tried playing about with settings, giving it time to cool down; pretty much everything I can think of, I really can't think what it could be, it seems to be many issues rather than just one, with it only being a month old, I expected slightly more.
Love the phone, did brilliantly yesterday; used it for lots of things; then today it just suddenly went, took it of charge, and it played up the whole way through.
Given up with it now, will take it back and see if I can get it fixed, I have 24 month warrenty with my contract.
Thanks
Put your original firmware back on if you can before attempting a warranty claim .

[Q] SGS2 i9100 bricked (Stock ROM, no root, no oveclocking)

First I apologize if this is an already discussed issue. I searched for something similar, but could not find any. If you think this is a repeat, I would be grateful if you can give me a link.
Now, my story. I have been using my SGS2 from July 2011 and happily so. My last phone is an HTC Desire (which I still use) running CyanogenMod 7.0.3. However, I found TouchWiz's annoyances less troublesome than HTC Sense, and did not do any modification on my SGS2. Not even root. Still running stock kernel.
Today, I was taking pointers during a conference using the Samsung Notes App, occasionally taking the SGS2 in and out of my pocket as required. At one time, when I took it out of my pocket, I found that the display did not timeout, and the Samsung Notes App was showing. I tried to tap on the edit icon, and nothing happened. I pressed the "Home Button", nothing happened again. And, still nothing happened when I pressed the "Power Button".
I took out and put back in the battery, and pressed Power Button, but still nothing was showing at all on the screen. I put the phone in my pocket for the conference to end, but after 5 mins or so, I noticed my pocket getting noticeably warm. Taking the SGS2 out revealed that the area around the camera (probably where the processor is) was quite hot. I took out the battery and kept it separately in my pocket.
When I got back home, I tried to put the battery in again and switch it on. No response, same as before. I plugged in the USB charger, and still no response, and the processor area became quite warm if the battery was in.
I really do not know what went wrong, or what I did that triggered all this. Is the hardware gone for good?
There are also some important documents on the phone that I created using Polaris Office, which are on the phone memory. Even if the phone is lost, is there any way that these documents can be retrieved?
I have not contacted Samsung Support yet, but before doing that I was hoping perhaps someone over XDA with more knowledge than the techs in Bangladesh, would be kind enough to give his opinions.
Next time, install Dropbox and/or Box and/or Minus and make backups.
This time, good luck getting it fixed and your data back.
Thank you for your suggestion. Any idea if this hardware is gone or not?
Can you enter download mode? If so, it's not bricked. Take out the battery, then put it in, hold volume-down and home and turn it on.
If you cannot enter download-mode, it's bricked. If you cab, I can help you make it running again. If this is the case, three are two possibilities. A software- or a hardware-fault. If it's the latter one, you can just get you device replaced. If it's a software-fault, a J-Tag-repair would do the job.

I tried the download mode earlier, and I tried it again now, still now help. No activity at all! How do I find out if this is a hardware fault? Is the processor area heating up any indication of a hardware fault?
So, no access to download mode? ie the screen stays blank with no sign of life.
If so, then I think all you can do is send it for repair/replacement.
Honestly, if what you're saying is true and one day your phone just stopped working it sounds very unlikely its bricked. Unless you're running at OC'ed frequencies or really low voltages I've never heard of a phone just giving up and bricking itself. If you really cant get into DL mode then sent it for repair but are you doing it correctly? Power button + volume button down + home button, don't just press it, hold it until you see something happening.
That was what I thought, how could it just go kaput without any "dangerous" things that I could've done on Android. But, I didn't do anything, at all. No custom kernel, no root, no overclocking.
And, I can't get into DL mode either. I tried to hold the Power Button + Volume Button Down + Home Button, and held it for over a minute... and still no movement on the screen.
On top of that, the area around the camera just got HOT... The processor is probably located there.
I even opened the battery and put it back in, didn't press any buttons, just connected the charger. Nothing happened, except after a while, the area around the camera just got HOT...
So, no ideas other than talking to Samsung support in Bangladesh? I hope they are cooperative!
Have you tried with a jig USB adapter?
http://www.amazon.com/SainSmart-Dongle-Samsung-Captivate-Vibrant/dp/B0053H73JQ
Switch of the phone, plugin the jig and wait 5 sec.
https://www.youtube.com/watch?v=9YRPWU4waa4
Brings you to the ODIN mode. I suppose, if this does not work, something is wrong with the hardware.
It seems an hardware failure.
It increasingly seems like a hardware failure. I went to Samsung office here in Bangladesh, and to my utter surprise, they refused to honor any warranty for an "out of country" purchased phone.
I got this phone from India, and just read the terms & conditions on their website. It says, the "warranty card" should've been filled out and sent back to them within 2 (two) weeks of the purchase, which I did not do. Increasingly it seems, I am out of luck totally.
It cost me around $700. I bought from an authorized store. And, still, I get no service. Very disappointing.
Have you tried using a jig? You might get it into download mode and then you can flash a ROM with ODIN
There is no activity on the phone at all. No display, nothing. Do you still think the Jig might work? The area around the camera gets hot when the battery is put inside.
seem like hardware issue..
if software prob it should able to bootup and show something on the screen..
do it have anylight on screen/button?
did u try usb jig?
if no i think only way is bring to Service Centre..

[Q] Tablet Turning Off....

I have been noticing this problem since the last 1 week. I never faced this problem earlier. Even with 50% charge, when I turn the display off at night, by the time I wake up in the morning, the tablet refuses to turn ON. When I put it on my cradle, the light turns RED suggesting that the tablet had discharged (which is strange cos I turned Wifi Off before going to sleep.) The only way to turn the display ON (even after charging the tablet for some time) is to click the Reset button.
On Resetting, only on one occasion I found that the tablet had really lost all the juice (which is strange) but on all the other 3-4 occasions, after the reset I saw there was atleast 40% juice left. So it is really strange why the tablet would not turn ON.
I never faced this problem when I had GB. Could this be happening after the ICS update?? Has anyone else faced a similar problem??
Please reply
(I am currently in US but am going off to India in June for a year. Hence if there is something wrong with my tablet, I will not even get a warranty out there. So, unless this is a common problem for everyone, I am considering to sell off my tablet as soon as possible and get some thing else......possibly a TF300)
I have noticed similar issues with my previousley UK tablet and now US with ICS (rooted).
Putting the tablet to sleep and coming back to it later finding it's completley dead and the only way to wake it is to hold the power button to power on or to recharge and do the same .
Thanks. So maybe I am not the only one.
My suspicion is that it is either with the ICS update where something has gone wrong causing the tablet to go to a deep sleep sometimes (This doesnt occur all the time.........just time and often)
OR
Since my tablet is about 6 months old now, maybe the battery Sony had provided is not good enough. Probably it has already started dying.
can others confirm whether they notice any such problem as well??
Note: It doesnt go into deep sleep all the time. Just about 2-3 times a week, I'll notice that it has gone totally dead and the only way to wake it up is to click the reset button and reboot the tablet. (On two of such occasions I noticed the battery completely died........while on the other cases after waking up it still had 40-50% remaining)
Why don't you send it back to Sony to have a look since its still under warranty?
I have been asked to do a reset and factory data reset to see if it solves the issue. I shall be doing that. However, the problem is that this issue does not occur every time. I have noticed it happening one or two times every week. Its not that every time I turn the screen OFF it refuses to turn ON and hence I need to do a soft reset.
The Sony guys still advised to do a factory data reset and then contact Sony for repairs if it doesnt solve the problem. So that's gonna be like another week till I know for sure (If I notice the issue) if it resolved the issue OR I need a repair/replacement.
I have a new tablet (2 weeks of use) with US ICS installed usingh AIO and experienced the same thing twice. I think it's the PS emulator, since the app was running when this happened.
Both times It refused to power on and I had to hold the power button for a while.
I'll keep and eye on it and let you know.
I have a similar problem. It also occurs intermittently and has only been happening post is (rooted in UK with region change).
Yesterday I went out for a couple of hours and left my fully charged tablet in standby. I when I got back it would nt turn on. The green mail notification list was flashing so I knew the battery was ok. Fake I plugged in the charger and the power light was yellow. I waited about 5 mins with the tablet charging and then pressed the power button and it rebooted.
On reboot, then battery showed 50%. This happens maybe once week.
Sent from my Sony Tablet S
Thought I'm the only one who face this issue.
Mine is wifi SG version and happen once under HC and one more time under AiO US ICS firmware.
Both times I need to do a reset before it came back on.
Good Bye Tablet S
Sony customer care and technical support proved useless in identifying the issue. I pointed them to this and other forums where the same issue has been repeated. I have been asked to Factory Data Reset the tablet. Even after doing that I am facing the same problem. (Once a week now).
When I called them up again, they said I need to send it over to them for service and repair where they will try to diagnose the problem and possibly repair it if required.
As I am going back to India in mid June, my US warranty will be void on the tablet. So I did not want to continue with the Sony Repair process (cos chances are high that I'll face the same problem again and at that point there would be no warranty on the tablet where I could get it repaired/replaced for free).
So, with a lot of burden on my heart, I have moved on to Transformer Pad TF300.
I really loved my Sony Tablet S. However, the software support from Sony really isn't good. They are at least a lot better in the smart phone department.
Will probably go for sony once again when their next generation tablet comes out. Adios........and Good luck to all the tablet S owners.......I hope Sony fixes the issues.........cos customer satisfaction should be the no.1 priority for a company in order to compete with the very best.
As per sony dealer here in Saudi Arabia, sony's warranty works around the world, I asked specifically cause I'm not from here & planning to go home soon

Lumia 920 Freezing... Hard

I picked up my first 920 from somewhere other than ATT. It initially had an small issue with its audio where the external sounds were not initially enabled. I did a hard reset to be sure, and both times it was off. Got past that and the phone seemed ok, until I unplugged it and hit the power button and it froze... HARD! No response from any button, or combination of buttons. I returned it and went to got the next one from ATT. This one started out perfectly, had no issue with sound. Then during a call it FROZE. Not as hard as the first one as connecting power and holding the <Volume Down> and <Power> buttons for 2-3 minutes finally rebooted it. That I have similar experiences with two phones says that there may well be something wrong the phone in general, and I am very surprised that I have not found it reported by others here. Have I missed something?

No, I don't think you have. The majority of them have been fine. In fact, mine has been perfect so far. Maybe the place you got yours got a bad batch?

Mine froze while trying to post using board express. It reboted and was fine. Other than that, no lockups since and I'm a heavy user.
I've also been having problems. After heavy use, it becomes very warm and tends to lock up.
I just uploaded a video to YouTube showing this.
http://youtu.be/x0KtZ7VCcTE
I can cause a hard freeze when jumping from bluetooth audio and back when nothing is selected to play. Other than that great phone..
Have this same issue with bluetooth - phone has locked up 4 times in two days. I didn't notice a correlation with nothing selected to play, so I'll check that. Typically I get into my car and the music just starts playing, and when I leave it pauses. Now it'll freeze when I get in and my car will say "Windows Phone operation not supported." After a minute or two (I usually power off the car stereo) the phone will come back with the song queued up at the top (as if I hit the volume). I hope this is addressed by the fix coming out in December.
Other than that the phone has been great - no issues.
Second Returned
I was in the middle of a conversation today and it just stopped. The call didn't drop, the phone just stopped, locked up hard for the second time. I return it and got a replacement (last day I could do it). It concerns me that there has not been more traffic about what seems to be a major issue with the 920

There's loads of complaints about this problem on the Nokia support discussions website, but there isn't a single common cause. Some have SIM card problems while others are blaming specific apps. Whatsapp and Facebook are two examples as well as Nokia Drive + Beta. Others have reported their phones freezing up after using a wireless charger.
Personally, I reckon it's the WP OS isn't at all stable and needs a serious patch.
We bought 2 at once - the one keeps freezing and the other never froze once. Both are using BTooth. However both are randomly rebooting, which I know they are patching.
But I wonder if the freezes and rebooting are related?
Mine hasn't rebooted to my knowledge but it does regularly freeze. It froze again on Friday and now refuses to power back on. I've repeatedly tried the two button and three button resets but the phone won't even vibrate. I've left it on charge using two different charges and tried the wireless charging plate but it's still dead.
Looks like its off to repair then. Not a good few weeks with the 920.
We took the one phone back to have it replaced. ATT obliged because it was within 14 days.
Still freezes. Only happens when on BTooth in the car.
I really hope a software updates this because it is a deal breaker!
Try setting the highest data speed to 3G for a while and let me know if that helps...

Mine freezes overnight when charging it with a wireless charger. every.single.time. Back to the store today as it is clearly defective, new one is already pre-ordered
Guys I have a strange problem with my lumia 920. When I use the phone while it's connected to the wall charger sometimes it's touchscreen becomes unresponsive. When I have to lock and unlock the phone using the power button everything again becomes normal. This happens quite a few times while charging.
Other than the above mentioned problem my phone froze once for which I had to do soft reset.
I want to ask is this happening with me only or others are experiencing it too.
And is there any solution to it??
Thanks in advance.....

[Q] SGH-i777 Power button not responding at ALL

Hello
I just registered for this site. I watched the video explaining to me that I'm a noob, and appreciated it. It put me in my place.
I have a Samsung Galaxy s II (for at&t; SGH-i777)
It is about a year and a half old.
I have not rooted it, everything on it is as if it were out of the box. Nothing is changed from the default settings.
I have upgraded to 4.0.4 though.
About a couple days ago, the power button stopped responding completely. I took out the battery and reinserted it which caused the phone to restart but did nothing for my problem. I have called Samsung (they told me to send it in for repairs: costing $70) I would love to get it repaired without sending it in or parying that amount. I have seen options of getting it rooted, downloading an app to transfer the powere button function over to the Volume down button function, but I don't really know how to go about that.
Therefore, I ask you, O'people of XDAdevelopers, do I have any other options? I did search the site for a problem similar to mine, but everyone else has their phone rooted. I am also unfamiliar to any technical terms. I am a noob to the fullest. I don't know how to root the device or even what things would be neccessary to root it.
Any help would be much appreciated it. I am willing to do anything.

As far as rooting and finding software workarounds, you can easily find all of that info by searching and looking at the stickies.
From a hardware perspective, I would recommend taking apart the back shell of the phone, and try to see if the power button responds by pressing it without its plastic cover piece.
If you have any soldering ability you can replace the part yourself for under 10 dollars. Search eBay for it

Hey man thanks for the help. I didn't get a chance to try out your method. A couple days ago, I woke up and the problem was completely gone. The power button was fully-functional and my phone was working perfectly.
Unfortunately, today, my phone has started acting up again. It keeps restarting on its own. It shuts down while I'm using it and it restarts. Nothing seems different so I start using the phone again, and it happens again (it restarts). Its restarted today around 7 times. My power button is functional at the moment, but I remember this exact sequence of events leading up to my initial problem where the phone's power button stopped responding.
What do you recommend?

I have no such ability. I could follow instructions but I myself am not good with that type of stuff. Fortunately though, this wasn't necessary. The power button started working on its own again without me having to do anything. Everything was fine until today, my phone has started acting up again. It keeps restarting on its own.

Wait.. so even though the phone is working fine today, there's still the possibility that its going to completely fail? It stopped restarting on its own once I took the cover off. I had the Otterbox cover for SGH-i777 on it, but once I removed the cover, the phone has been working fine. Do you think there's a connection between the cover and the restarts? (I would post the link for the otterbox cover to show you, but I can't post links since I'm still a newcomer)

Possibly. I was experiencing reboots months ago with a trident case. I'm now using no case and haven't had any issues.

First off, have you checked to see if there’s another update? There were two 4.0.4 updates released for this phone. There was one back in January, I believe, that introduced the sleep of death problem, as well as causing a lot or seemingly random reboots. Some of the problems you describe definitely sound like these. They released another update around March that was supposed to fix these problems. That update is also 4.0.4, but should be UCLL6.
The power button issue is also a well known problem. When mine starts acting up, the first thing that happens is I’ll press the power button and the power menu will come up as if I’m holding the button down. Then a few seconds later, the phone will reboot and usually the power button doesn’t work after. It’s likely a design defect and will fail eventually, but there is a solution, if only temporary, that has worked for me and several others. If it starts happening again, pull your battery and press the power button repeatedly. Some people have gone so far as to press it several hundred times. I usually only press it a couple dozen times, but the problem does comes back for me eventually and I have to do it again. Interestingly, most of the people I've seen reporting this power button problem have had it start in the last couple months, around the year and a half mark. Not trying to say anything, but very awkward it started happening right as the Galaxy S4 was announced
I had this problem and tried all the workarounds but they didn't seem to work or was buggy. I ended up having to send it in to Samsung for them to fix it (luckily it was still under warranty). It ended up being a hardware issue so you may need to send it in to repair if you cannot fix it yourself with the methods in this post.
Those with power button issues, try this app:

Works great, and the Dev has a thread for it on XDA.

I had almost the exact same problem with my Sprint Galaxy S II (Epic Touch). (Random reboots every couple of days, which got progrssively worse. Eventually, I noticed that just brushing the power button would cause the phone to reboot ~10sec later.) It ended up being a bad power button, and replacing it resolved the issue.
How handy are you with a soldering iron? If you're pretty good, you can buy the AT&T i777 S2 switch for about ten bucks and replace it yourself. (You can also try cleaning it for free - several tutorials here at XDA. The Samsung "Captivate" and "Epic 4G Touch" have similar switches and and the same problems. Search both forums.)
Several eBay sellers have the switch you'll need. (They don't provide the skills needed to solder it in place - but your AT&T phone will be easier than the I897 Captivate or D710 Epic Touch. Your switch is similar, but a larger size.)

I've having that problem on mine it's still on Gingerbread. The power button seems to be clicking normally, it doesn't seem stuck. Yet anytime I stick my battery in it automatically cuts on and the screen seems to shut off without responding to the power button. I cannot reboot the device. I cannot turn the screen off/on without plugging it in or unplugging it from charger.

You could remove the power button entirely and rely on the Gravity Screen On/Off app I linked above. I have never tested it on GB but it should work, as It relies on the sensor. Removing the power button shouldn't be difficult at all, as you can access it by removing the battery and there are several tutorials on how to do that (i9100 tutorials will work just as good).
Perhaps some of these ideas will work for you?
My current phone has a failed power button. I didn't bother removing the power button, as it is unnecessary. I use Gravity Screen, and an app called Power Menu to replace the power button long press menu. I just pull the battery to turn the phone off, and for rebooting. Works acceptably well.
Of course the other option is to have the power button replaced, which is about $40 plus shipping, but this phone is so old it is hardly worth it.
