What version of the firmware are you on? The reason I ask is that the firmware that I had that came with the phone used to "seem" to do this. Are you sure you are not touching anything on the phone during the shutdown?
Ie. press and hold the power button, select power off, then click ok
Now dont touch anything at all on the phone until the phone vibrates.
Previously (I think it was on KE2) I'm sure it would cancel the shutdown if something was pressed.
It now seems not to do this since I upgraded to PDA:KG3 / PHONE:KG2 / CSC:KG3 (ORA)

I have Android 2.3.3..
Just tried to turn it off, and i did not touch anything, but it still turned itself on.
How far into the shutdown does it get?
ie. press+hold power, do you get the list of options?
if so, after selecting power off, do you get the confirmation prompt ok/cancel
if so, does the shutdown graphic kick in (i'm on orange, so an orange video gets shown.
You may have to pull the battery out. This can cure lots of strange behaviour in most phones.
I've tried both, when I get the list of options i choose turn off device, and then it comes another screen "this will shut down your phone" and I press yes.. and the shut down video appears. and i it turns off but seconds later the start screen shows.
I've also tried to just hold the button on the side til the phone shuts down, same thing happen.l
When I turn off my phone, it take i couple of seconds and i turn itself back on..
Anyone know why? Is there anything I can do about it?
I do have exectly the same problem. I'm about to go to the shop where I bought my phone, maybe they can help me. I guess it has something to do with the latest software (called a batterybug on the internet)...
If I get to know anything I will let you know...
And it's not the power button because it would ALSO shut down by itself and turn on by itself...

I experienced the same problem, after installing Modern Combat 2 which I had downloaded earlier today from Gameloft. On balance, I felt that writing off £3 was less irritating than having a phone which wouldn't switch off.
The phone now switches off and stays off, so it was either a wierd combination of T-Mobile, Samsung, Android and the game, or just the game. Occam's shavers says the game.
And if Samsung/Android can come up with a fix, I still have the downloaded zipfile. It sounds like you may have downloaded something that is behaving in a similar way. Makes you think, doesn't it - who knows what hacks have been put into these games.

I had this problem too. I also had the MTP application cranking up all the time and scanning media. I went to Settings/Applications/Development/ and ticked USB debugging. This solved the problem and the MTP application starting all the time. Good luck.

I also have the same problem, and also my micro usb is not working properly. It is not recognizing either the AC Charger or the usb cable, if connected to the computer.

Clean the USB socket out with something like a dry toothbrush. Dust & debris can get in there and short out some of the connections, confusing the phone.
just been googling this problem and found this thread.I too had this issue except mine would stay off once battery removed and put back in. I had had my phone less than 28 days so I got it replaced and after about a week my new replacement is doing it again argghh!
I'm thinking it would be really bad luck to have issues with 2 phones so im thinking must be something I am doing.interesting to read a game loft game causing issues as I downloaded super knockout recently which is around time issues started.
Thinking I'll try remove that before sending this one back!
I'm with Nelviticus on this one if its not software causing a reset instead of power off. Give the usb port a clean. If there's around 255k across pins 4 and 5 of the USB port it will cause the phone to switch on.

i got this problem too..
but i've followed all of the tips...
but it's still turn on after shutdown...
i'm using hairdryer,toothbrush to clean my usb socket and its work..
but a couple of minute, it was suddenly turn on by it self...
whats wrong...
help me please...
it's really annoying...
is it because the usb socket get wet...?
but i've dryed it with hairdryer...
Hi, I had the same problem too, the details:
1. I have never used a different ROM than the original.
2. I haven’t upgraded the original firmware.
3. When the problem happened I haven’t installed any software (recently)
4. This is not a software problem definitely
5. The problem began when I have finished charging the phone (the phone was turned off), I disconnected it from the AC Charger and it began to show the battery icon like if it was charging and a yellow triangle advertising that the charger doesn’t have the sufficient power to charge. Then I tried turning on the phone (it was really difficult to turn it on), when I finally turned it on I noticed some problems with the data network (really annoying), when I tried to turn off the phone, it begun to restart instead turning off.
6. I have been goggling since then, only one thing solved the problem is to clean the USB PHONE connector (I used a small clip to clean), there is something unclean (I can´t see, it’s something very little) yet but the problem has gone, all is normal now.
7. Someone has a comment in a youtube video about it that says: “I had to turn it in to the local samsung service location. They told me that it was corrosion in the USB port due to water damage. They charged me €70, and I'll pick it up tommorow.” This confirms the problem.
I am thinking that the USB connectors come with this problem, so we have to be very careful at the moment of charging the phone, maybe we should plug the charger to the phone before connecting it to the AC power.
Same problem here (Samsung Galaxy S2 on T-Mobile in the UK).
My phone will not switch off, in spite of going through its full shutdown sequence (including the final vibrate). When it finishes shutdown, it springs back to life with the boot screen.
I tried enabling USB debugging (see earlier message) but this made no difference.
I also did a factory reset (minus the SD-card wipe) and this too made no difference.
It is clearly a hardware fault. Several people on this thread have pointed to a short circuit in the USB port, which may, or may not, be the problem.
Weirdly, the phone *will* switch off when it is connected to a power supply (or USB). But as soon as you disconnect it, it boots up (without touching anything). This questions the USB short cicruit theory, and points to a more fundamental hardware fault in the circuitry.
My phone is new (two weeks) so I plan to get a replacement and hope that it doesn't happen again.
UPDATE: I took the phone back to a T-Mobile shop only to be told there is only a seven day exchange policy and that the phone will have to be sent away for repair. As you can imagine, I am not pleased about the loss of the phone for a period of time or the idea of my phone being repaired at such an early stage or, worse, me being sent an older exchange model.

Reason: More info added.
I think I now know what the problem is. The micro USB port on the phone has no cover and is exposed. It seems to be prone to getting a little moist, and this problem arises when that happens. I suspect that brushing the connection or blowing air is simply drying out the connection.
My phone now switches off OK. The problem arose after I used it at swimming. The phone was never near water but the air is moist at an indoor swimming pool. It has now dried out and it now turns off OK.
So, my advice for anyone with this problem is to coonnect a USB cable to it to switch it off, which will work for as long as it takes to dry out the phone.
This is a hardware problem that Samsung needs to address. I've used many phones at the swimming and never had this problem.
only thing i can think of it a clean install, of 2.3.3 maybe try 2.3.5 thats out now anyway.
WTF? Did you read my earlier posts on this problem? It's a hardware - not software - problem, caused by the USB connection. Installing software will not resolve the problem and will only further inconvenience people.
I experienced the same problem. I basically cleaned out my micro usb port with a small brush and removed my battery then reinstalled it. My phone had started to give me the chime and show it was charging when not connected. This is what pointed me to the micro usb.
I had the same problem but was finding the voicetalk client was loading by itself as if I'd double tapped the home button. power off the device, it would switch itself on again and launch voicetalk. Did a factory reset, still the same. Took it back to the Vodafone store, they did another factory reset...despite me telling them I'd already done this (duh!). Eventually Vodafone agreed to take it in for repair and then said it was the systemboard, which they replaced. No problems since this occurred.
I'm with Nelviticus on this one if its not software causing a reset instead of power off. Give the usb port a clean. If there's around 255k across pins 4 and 5 of the USB port it will cause the phone to switch on.
Thk you very much!
Ive cleaned it with a dry tooth brush and works perfectly!
cant thk you enough! would never thought of that! ;D
Mine does exactly the same. It is the worst decision ever buying this phone. that is just one of the problems. The battery lasts 4 hours, Driving Mode and Voice Command turn themselves on, it freezes, answers calls on speaker phone. that is to just name a few!!!!!
I have the Samsung Galaxy SII, and found I could not switch it off. I could hold the button down, clear the warning about the phone being switched off and it would appear to turn off. A few seconds later the lights on the virtual keys would light up and the phone would start up again.
I tried cleaning the USB port and still no joy.
So, I let the phone run down until it shut down by itself, then I removed the battery for 23.6 seconds (LOL!) then reinstalled the battery. It did not start up (good) and plugged the phone into the mains charger until it had finished charging. I turned the phone on, and all was good, and shut the phone down and it stayed off. I tested it several times and it seems ok now.
What must be remembered, is that this is a computer, and it's going to behave differently to the old Nokia 5110 phones!

Hi grizz1988, I would say you need to check your settings for 'answer calls on speaker phone', there must be an option somewhere. As for the other issue with driving mode and voice command, maybe you are accidently double clicking the 'home' button? And if you battery is lasting 4 hours, maybe you have a fault with the phone? When I tested my phone for the shut down problem (to discharge the battery), I had the WiFi, Bluetooth and GPS turned on all the time, played games and stuff on the phone and it kept going for 44 hours.
For me, this phone is simply the best, yea, it may have issues, but so does everything. It's a computer after all. For every thing this does, it's amazing.
I had the same problem...
Probably not the best solution, but after reading the post about the power button contact being permanently on, I removed my phone from the case, and then shut it off, and it worked! I know... pretty stupid. But hey, who knows, it worked for me!

If the battery runs out. I am screwed. I plug it into the mains and it tries to turn itselfs on. obviously there is no power in the phone for this, so it goes off. Attempts to charge again and the same process happens over and over.
Driving mode/voice command etc...Got nothing to do with double tapping the home button. I charge it of an evening, wake up and its on. So i doubt i am pressing it in my sleep. There are no settings for answering calls on speaker phone, once driving mode etc enables itself, then the phone continues to answer on speaker phone. Quite embarassing.
I don't have any apps on my phone, deleted them all and started again. Battery life still poor. Phone freezes on multiple occassions.
Hurrah, it seems I'm not alone. I've had the 'driving mode' issue for a few weeks now - IIRC it started soon after an official s/w upgrade just before Christmas. however, I also rooted my phone (but no changes to ROM's etc) over the vacation, so that may also have something to do with it. The Vlingo software certainly seemed to be causing the phone to start up automatically, irrespective of whether it was 'asleep' or off.
Two nights ago, I had the 'SD card cannot be read' error - the cards and contents are fine (can be read on a variety of Win pcs), so I'll try the 'clean the contacts' option.
Otherwise, it'll be a factory reset and a warranty return.
will let you know how I get on, but very glad I'm not the only one.
I did see some other comments on the Vlingo s/w being hard to remove / turn off - it does seem to have a mind of it's own!
cheers
h.
I had the same issue with my T989. I have traced it down to the T-mobile boot up and shutdown animations which I removed. After restoring the animations back the phone shuts down and stays off. What I did is rename the obnoxious starup and shutdown .wav files so I wont hear that music anymore.
I had this problem too. I also had the MTP application cranking up all the time and scanning media. I went to Settings/Applications/Development/ and ticked USB debugging. This solved the problem and the MTP application starting all the time. Good luck.
actually i am having the same issues accept i don't have calls answering themselves. My battery dies in about 4 hours because the phone constantly loads voice command and MTP and as quickly as i can shut them down they are running again. I was having the issue with the phone turning back on but after selecting usb debug as sugested it seems to be staying off at least
I too had the same problem last night and took some advice found (buried) in this thread, which completely solved the problem.
Symptom:
My phone was not charging, though the indicator on my phone was telling me that it was charging. In addition, my phone wouldn't stay off when I turned it off. Within seconds of me turning my SGS2 (i777 - at&t) off, it would turn itself back on.
Problem:
On my phone and I suspect other peoples' phones as well, it was the connection between the USB cable and phone, where they both meet at the micro-usb connector. Either the cable, phone or both were dirty and corroded, though that dirt and corrosion wasn't visible.
Solution:
I gently took a toothbrush and q-tip to my phone's usb port and the same thing to the micro end of the cable. While this worked to turn my phone off (when it was disconnected from the cable), it did not help me the charging issue. I wound up buying a new usb-micro cable at the store for $15 and now my phone is back to normal again.
Analysis:
I seemed that both my phone and cable were corroded at the connection where they meet. Some people with this issue may be able to get away with just buying a new cable (or clean their old one properly). Or, simply clean the usb-port on the phone with a toothbrush and slightly modified q-tip. However, it might be wise to clean both the cable and phone because they were both quite intimate and thus likely share the same corrosion or dirt.

my Samsung S2 will not stay in sleep mode! when I lock it, the lights go back on in about 2-3 sec later. I've tried turning it off, taking out the battery, nothing helps. can anyone help me?
and when I shake my phone, I hear click-click. I've tried holding all the buttons when I shake it, and it still clicks. I've tried holding all the buttons, taking out the battery and Simcard, and it still clicks.. should I go to an electic shop ?
My symptom was that the phone would not be switched off, as per other people in thread.
Cleaning with a small (clean!) nailbrush worked for me; I could see a little corrosion/dirt after peering in the slot with an LED torch. Gently rubbing from side to side with the nail brush seems to have fixed it. Thanks all you clever people!!
Edit: @Brynhild. sounds like something loose in phone shorting the main button, as you suggest, get it looked at.

i am having the same issue, but in addition to that when i turn off i got a sign on the screen of a temperature on the battery. did you have the same issue?
i am having my phone for almost a year now, but it just happened now days.
my daughter has an LG Optimus, i have a samsung gII.
one night, her phone was charging on the AC and suddenly the screen went white and started blinking on and off, on and off. i couldn't do a thing with it - battery pull didn't help. after doing a bit of research, it seemed the problem was the battery was drained too much (? it was at 3% when i plugged it in) so i plugged the phone into the computer USB charger while i looked it up some more. got sidetracked, played a couple games, and when i looked over, the phone was off. i turned it on and it showed 4% charge and charging, perfectly well behaved.
today, my samsung GII wouldn't shut off - it would shut off, but the moment i plugged in the charger, it turned back on and wouldn't stay off until i unplugged it.
guess what? same charger.
i plugged my phone into the computer USB for charging and it shut off and the battery symbol came up as per normal.
i will, however, take heed of other posts and clean out the USB ports. they've always bothered me, them being wide open like that, but i didn't want to go messing around in case i wrecked something.
