[Q] Samsung GalaxyS2 won't power on - General Questions and Answers

Hi everyone, I appologize in advance if this has been posted and resolved, but I couldn't seem to find anything after numerous searches.
I have a Samsung Galaxy S2 that I have had for JUST over a year (i think June 30th) Everything has been fine, no problems and today I was on it, working fine and then all of a sudden it shut off and then started to reboot. Only when it powered back on, it showed the black SAMSUNG GALAXY SII powered by Tmobile start up screen, then went black, then the startup screen appeared again, then went black...repeat.
I did a battery pull for 2 minutes, same thing. Did a battery pull for 1 hour, same, I left it on the chargert for 4 hours and while on charger kept blinking on and off but now only the grey battery (even now off the charger)
It has never been rooted, or updated or anything like that. There is no water damage at all.
I have a wall charger for the battery only and an extra battery and have tried charging both batteries with that and still no luck.
I have also tried plugging it into my computer to see if it would boot up that way and nope. Still just the on and off dead battery, not even the startup screen.
HELP PLEASE!?

power shortage?
Has there been any kind of problems with your electric house system? that happened to me once, and it was due to a power problem at my house, it basically blew off my battery. Forget about battery pulls. Go to a store and ask them to lend you a battery for a second. If it powers on fine, it's the battery. If it doesn't i think you should get yourself a new phone, or try to get it fixed at the customer service. Sorry for the bad news man...

Nope, no problems with electricity, and neither of the 2 batteries will work!

P6810 suddenly won't turn on

Anyone come across this? I put it on standby last night after reading a bit of my book on it, and it had around 50% power remaining. This morning, it was totally unresponsive; pressing the power button does nothing at all. I've charged it for 12 hours in the meantime.
I've done the following all with and without the power attached:
- Pressed and held power for 15 seconds through to a minute
- Pressed and held volume up with power to attempt to get into recovery for up to a minute
- Pressed and held volume down with powerfor up to a minute
- Pressed and held power while touching screen (read that one off another forum)
I guess potentially it could be on and in a crashed state and unresponsive to the power, so maybe in a weeks time when it runs out of juice, I'll be able to charge it and power it back up, but in the meantime, I'd welcome suggestions.
A few weeks ago I updated it to the official ICS build that was released, but did the update myself rather than using KIES, as KIES didn't even recognise my Tab's firmware original version. It's been absolutely fine before the update, and since. I only mention it because I've read about the Samsung build of ICS being prone to self bricking itself, but I couldn't determine what the symptoms of this vulnerability were.
Thanks for any help offered,
Will
did you try connecting USB cable and plugging it into your PC? did u get any activity? can ADB recognize your tab?
I think your tab just ran out of juice and the battery's protection circuit has kicked in. Try taking it to an electronic shop and plugging in different chargers preferably one with an output more than 2.1 amps to kickstart the charging. Plug it in and wait till the charging animation starts.

Had the same problem while on holidays. Once the battery goes below a certain level, you won't be able to charge it through USB any more. Instead you need to use the wall charger.
I think it's bad enough that the 7.7 doesn't have a micro USB port, but things like that are just stupid and Samsung made a big mistake here. It don't think it's the same with the newer tablets though. It's also not possible to just buy cables or chargers for this strange Samsung port, so when you forget your wall charger at home at some point you won't be able to use your tablet any more.
As long as you charge with the USB cable early enough, you can avoid it though.
A few months ago I experienced the same thing, the Tab just wouldn't turn on anymore.
I tried all there is without any luck.
Contacted amazon and they replaced it with a new one in less than 48 hours.
So far not Problems with the new device.
I have the P6800 and this morning I took it off charge. Put it into standby and only used it for about 20 mins then left in standby all day. It had about 95% remaining when I did so.
Picked it up this evening and the lower left area of the screen was warm and it would not switch on. Didn't think of the ADB idea but will try this next time but I had to reset it and when it powered on tonight after the reset, it was down to 15%. Within about 2 mins of checking stuff it was down to 3%.
Something is running when it is in standby but as I can't switch it on I can't check with BetterBatteryStats or CPUState to know what is wrong.
It does this every day. I am tempted to do a factory reset and reinstall only limited software.

I see this thread is a little old but this has just happened to my P6810 too. A pity nobody reported back what the end result was.
My device had at least 95% battery last night but today I can't get it to respond at all, I've tried the wall charger and still nothing.
Anything else someone could suggest for me?
Edit. I tried getting anything from it connected to my PC but it couldn't find a device there. However I then tried it on the wall charger again and now get a blue battery icon, quite big, with a five step animation indicating that it is charging.
No idea how it went flat as the battery on this lasts a long time assuming the screen isn't on. When it boots properly I'll have a look at what the most recent apps I installed were as it has only done this once. Before this it has been perfect for the three weeks I've had it.

This is the infamous Sleep-Of-Death issue that is randomly experienced by myself and other users here, usually happens when WiFi bugs out due to weak signal

hhmmm, interesting.
I was having trouble with wifi just before this happened. Both my GS2 and this have been claiming to connect to my wifi but aren't actually getting an IP address from it.
I can't remember if it was last night or the night before but I manually set an IP address, the signal strength is fine as my abode isn't very big.
After it has recharged I'll have a poke and see what I can find, thanks for the reply.
So my device seems to be working fine again. It had gone SO flat that the date and time were incorrect!
After I could power it on I had a look at Better Battery Stats and nothing looked wrong so I have no idea what happened. None of the apps I'd installed the day before it played up had long wakelocks and weren't running when I turned it off.
For reference they were:
My Tracks
MyTrails
Google Earth
AndSMB
I'd turned both of the GPS tracking devices off before I turned it off for the night.
It hasn't played up since but it hasn't been long so I'll see what happens.
Yeah, the sleep of death is incredibly annoying. Honestly, the GTab 7.7 is a **** device. Samsung made way too many mistakes and won't do anything to fix it.
A similar thing happens to me every once in awhile. The way i check to make sure everything alright is to see if it boots into download mode. I just leave it plugged in for a couple hours and it eventually comes back on.

this is why my 7.7 is the last tablet/phone from Samsung i'll never trust them they are just bombarding the market with new devices and leaving the old ones to dust
^thats what I thought too but that gs4 is really tempting. I've heard worse about HTC in that regard anyways so that why I'm not going with the one.
Finally.. i bought Sony xperia Z.
I'll sell my galaxy tab 7.7. I.m very disappointed with samsung.

Unbelievable! ... this trick still works ... thank you very much for you help ...
^^ yo, this 'trickle charge' trick did NOT work on my (long) dead P6800... any other suggestions??
Quite strange because my Samsung GT-P6800 tablet was fully charged, it went completely blank dark as if it was off. To my amazement, SMS keeps dropping and calls kept coming in. Yet it is still as blank as though the tab was off. I pressed the power button and the volume up bottom for it to reboot. It rebooted without the screen coming up. It has been blank for two days now. What could be the cause? And what possible solution can be given?

Did my S3 brick itself?

Looking for any help or guidance here. I searched the forums and have found limited info fitting my situation.
My S3 is rooted running Jelly Beans Build 15, today I was sitting here playing a game the phone was in use for a while so it was warm to the touch as it can normally become... mid game there was a slight flicker of the screen and it DIED.
Since then I can not get any power back. I pulled the battery, and tried to power up I get a vibe then nothing happens. I've tried to reboot into DL or recovery all it will do is vibe then nothing happens.
I plugged it into the charger and it will vibe, the LED doesn't come on, and the battery icon on the screen will flash on and off the screen, each time it appears there is a short vibe.. with all that the phone won't boot.
I've had it about a year. SO did it just sh!t the bed on it's own??

My first S3 did almost the same thing one day. My wife and I both got them on launch day and mine always seemed to run out of battery a bit faster than hers. One day, it got really warm in my pocket and the battery started draining out of control, it dropped 10% in a few minutes and just kept going until it was dead. Plugging it into USB to charge, it vibrated, I got the big battery icon on the screen, then reboot, vibe, icon, over and over again. I had to exchange it with Verizon.

Any chance you could get your hands on a different battery to try? I was in class once playing some dumb mini putt game some guys played next to me, and my phone just completely shut off. I couldn't get it to turn back on and at the time it turned off I had ~half battery. I got back to my room and put a different battery in it and it worked fine. I charged the battery that wouldn't work and it now works fine again. Not really sure what the problem is though...
But yeah. Find another battery to use to get it to boot back up
So the phone is alive and working. It seems there may have been an issue with the battery level and a bad reading. When the phone died it read 20%, I hooked it up to a usb power cable on my pc and work and it didn't work.
When I got home I plugged it into the OEM charger and it was showing the battery was essentially dead and charged the phone back up...
That's all that happened... strange but true

I think you have the same problem I did. When my phone completely dies and I plug it to the charger the battery charging icon goes on and off or if I get lucky stays on and charges it. But I put the same battery o. Another phone it charged instantly. I got a replacement from verizon.

Galaxy S6 keeps turning off after being dropped into water

Hi at all,
about a week ago my girlfriend dropped her Galaxy S6 into the toilet (NEVER put your phone into your back pocket).
After some days of drying I was able to turn it on while plugged in and except for the battery everything worked. I replaced the battery and everything went back to normal. Sometimes the battery wouldn't charge over a specific level and sometimes it just turned off but since yesterday it keeps turning off as soon as I can see the lockscreen. If it's plugged in it stays on and I can use it as always, everything still works, but it's basically impossible to use it without a charger
What could be wrong? How I can identify the source of the problem? Is there a log I can use or some diagnostic tool?
Thanks a lot,
Thomas

Did you use an oem battery? If after using a genuine Samsung battery you still having issues, it may point to the charging part of the motherboard.
The battery I bought was sold as "official" Samsung and it looked exactly the same. I also didn't buy the cheapest one so I guess that's fine. I don't think that it's a problem with the battery since the phone boots up until the lockscreen appears and then shuts down. If the battery was dead it would crash at any random point and not always at the exact same time. The overall behavior is pretty strange since it stays on and works perfectly fine as long as the charger is connected.
So is there a log I can search through? Mayber there's some kind of low voltage warning or something like that. Otherwise I'd have to sell it as a defect device on ebay and I would rather like to keep it

[Q] Possible virus?

So I made sure to look it up but couldn't find anything so here I am.
Anyways I have a Samsung Galaxy S3 (I747) rooted and running Slim OS, but I haven't done any mods or customizations in awhile. The battery was getting low so I, of course, plugged it in, but it was still dying, which isn't strange, it occasionally does that, so I just let it die. After awhile I turned it back on and it was on 6% and after awhile 5% now I thought it was strange since I wasn't doing anything too power demanding and my charger is a good charger, then at 2% the screen turned off and wouldn't turn and I even tried holding down the power button thinking it might've turned off but that didn't work, I left it charging and even took out the battery and that didn't work and then I noticed that the charging screen didn't even pop up whenever I plugged in the charger. Now fearing my phone is messed up I took out the SD card and put into my Samsung galaxy camera 2 and the battery started going down quicker than usual, it was at 58% and after like 10 minutes went down to 32% and then it shut off like my phone, but unlike my phone, my camera is unrooted running stock android. Please help
Or the SD card could be causing problems.

Quick update
So my camera turned back on and it now works, although I rooted it and now theres some problems, but this isn't the right section for that, but anyways, when I plug my phone up it does get warm unlike the first day, so I assume it is actually charging

AT&T S6 Possibly Bricked

my mother has given me her galaxy S6 that may be possibly hard bricked. she already got an upgrade done for an s*, so she isnt in dire need of getting it working, except to get her pictures and files off it.
it started off when it was turned off and charging over night, and had the battery logo showing fully charged in the morning. unplugged the phone, and it just would not turn on at all. plugged it back in, and no lights or anything on screen would show.
She works at a local best buy, and spoken with one of the samsung experts there, and they informed that it could be a bad battery.
she ordered a replacement battery off amazon, fast forward a couple days, it comes in, and i replace the battery.
it still does not power on at all, even with attempting to boot to recovery, download mode, or anything.
the only thing different since replacing the battery is that now the led at the top of the phone just lights up white, and thats it. the only way to turn it off is it open it up and unplug the battery.
is there anything i could do or try to see if i can get any life out of it before declaring it dead?
