Phone turns off before booting - Sprint Samsung Galaxy S III

I was using my phone this morning, then the screen turned off after I left it idle. Tried to turn it back on and got the Sprint logo and then the Samsung logo shortly after, and then it would turn off.
I tried power + home + vol-down, and shortly after that screen comes up it turns off again.
Do I just have a bad battery? I'm using the Gorilla Gadgets extended battery, but I'm at work and don't have access to my original. I also noticed that if I plug in the charger, the charging light doesn't come on.
Anything else I can try?

Oh wow, thanks for the speedy reply and for the heads up. I'll go ahead and give this a shot when I get home tonight

Honestly this works. Either way the button will have to replaced If you want to spend the money.... for me this s3 is another android toy along with my s4... I've gone from the g2 to the s4 and back to a G2, it's the best phone out IMO

I don't doubt you at all, I just managed to confirm it. After slapping it around for a bit I finally got it to go to my home screen, then shortly after the "power off" menu came up, similar as to if I was holding down the power button and off it went.

I actually saw a video of someone flicking the power switch area with their fingers, I did that and managed to get the phone turned on, and have made sure to not touch the power button since then by installing a "screen off" app and it's been on this whole time. I'm guessing this is just a temporary fix and eventually it'll turn off again w/out me touching the power button?

Yep. It's going on vacation and your power button won't be returning

Is there a special method to take out that little brown piece? I'm using a small needle and it looks like it's made of hard plastic and completely wedged in there :\

Jessooca said:
I'm making a video tomorrow.
When you're looking at the button which is obviously in the middle of the switch look at that Brown cardboard looking material... directly behind the button in that cardboard area use a very small flat head after you've used that needle or pin then dig out enough of it, so you can stick your screwdriver behind the button and it'll pop right out.

Is it "A" or "B" that I'm trying to pop out? It still looks brand new in person, but the lighting and camera show every little scratch I've caused by prying at it with a needle.

What you have is I'll guarantee 99.99% is a bad Power Button/Switch on your motherboard.
This was initially referred to as Sudden Death Syndrome... don't waste your money and buy a new battery, I assure you that's not it.
If you have a multi meter take your phone apart, it's very easy, there's a tear down video of how to on YouTube if you need a reference.

If anyone takes this advice PLEASE be sure to test with a multimeter to be sure this is the problem. I don't even know if the multimeter test will tell you anything (I'm no electrician) but this advice will permanently disable your phone. I was recently having a problem with my phone restarting and Jessooca guaranteed me that the problem was the power button.
The problem wasn't the power button. The problem was corrupt data/cache in one of my apps. Clearing the data/cache fixed the problem.
I just don't see how someone can make guarantees and be 99.909% sure of anything. Every problem can be caused multiple ways.
A few months ago I had a problem with my phone failing to startup and in that case it WAS the battery. So that's two different times I have personally experienced boot up/shutdown problems that were not related to the power button. It's just crazy to make guarantees and say you are 99.99% sure about anything without any troubleshooting. Especially for a problem like this that can have multiple causes.

I know I'm late on this thread, but just in case others come here looking for advice on how to fix their power button. I have fixed many of these by soldering on new buttons, and it's a pretty easy fix if you are good at soldering and have a good microscope. What's not an easy fix is trying to replace all those little tiny resistors and capacitors soldered on right next to the power button. They're about the size of a grain of sand, and although I usually can get them replaced and make the phone work, it takes much longer, so be careful if you're going to attempt any kind of diy repair!
I would also say that the only way I've personally gotten these power buttons to work other than replacing them is by cleaning them and lubricating them. A good electronic contact cleaner/lubricant works best, but acetone followed by WD40 works pretty well. Just saturate them with the cleaner and click them a bunch of times to work the cleaner in... then do the same thing with the lubricant. Doesn't always work, but it's unlikely to make the problem worse, and if you it doesn't work you can send it to me to fix!

[Q] Help identifying power-button (on the mobo) part.

Been having power button issues:
Power button does not work at all, not even when booted to recovery. I believe it is shorted/stuck on because the device CANNOT be powered off. As soon as the battery touches the device, BOOT.
So.. i pulled the case and took a look inside:
All the soldering looks fine but i assume its an internal mechanical issue. If anyone could help me identify this button on mouser etc, i would greatly appreciate it.
I am familiar with small package SMD soldering; however any tips as far as temperature and solder time for something this sensitive would be awesome.
Or a schematic? Any idea if one is leaked?
(that button) Not the plastic part!

The only thing close to a schematic I've ever seen for that are the FCC approval photos.
Hmm, ok i will take a look at those. I am really just hoping to find an equivalent part to swap out. May end up just taking measurements and scan through mouser for a few hours.

^Gotta love Digikey... tons of components.
That almost doesn't look like the right part though in the digikey pictures. Looks like it has 4 pins instead of 5.

Ha yea; i was surprised mouser didn't even have anything close.
It definitely just has 4 pins, i believe the 5th is just for mounting/was just soldered to the case. After going through thousands of these 'tactile switches', none of them had 5 pins.
AND: if you look at the techresourse teardown, their mobo revision doenst even have the 5th pin...or the ground wire from the silver box to the switch casing.
Glad to see progress is being made. I hope the repair works. Please if all goes well and works can you make a detailed step by step including all tools needed for the job? That would be awesome.

Ah ok. That's what I was thinking too that it was probably just a mount, but wasn't sure if it was a ground pin afterall or not.
Just figured I would point it out just in case so you would still have time to cancel the order if needed, but nevermind .
And yeah, a guide would be nice if somebody needed it in the future .

[Q] Anyone else worried about a power button issue?

After owning a Nexus One which had a power button issue and seeing my friend's Nexus S going through the same problem, I'm a bit worried that it will happen to my Gnex, especially after spending so much $ on it. The power button doesn't feel as sturdy as I would like. Are there any apps for ICS/Gnex which can change the unlock button to the volume rockers?
Anyone else worried about that? Or am I just freaking out in advance?
This is the first time I'm seeing it posted but I think my power button is going bad.
Its not bad yet but certainly feels like its getting worse.
About ten times a day I need to repress it cause it didn't work.
I have a case too which could make it harder but its still exposed so its not that I'm missing it.
Had me super worried at first.

I don't have this problem, but my Captivate did. I used screen off and lock. I keeps your phone from fully locking allowing volume buttons to wake the screen. I also used SGS button remapper to remap the buttons, but I don't think it would work on the GNex.
YES. Have been thinking about this for weeks now. My OG had to be put down be cause the power button completely broke. Since then I am a little snake bitten with my nexus. I actually find myself pressing and depressing more often just to see if it is getting worse.
Funny to see a thread of this.

Try pressing the button right in the middle. I noticed that you sometimes do not depress deep enough for the "click" to register when you hit it too far to the sides. The upside is of course that it's harder to press the button by mistake too.
I think you're freaking out about the power button not working.
Alternatively, like what others say you can get AOKP and do it with volume rocker to turn the phone screen on.
Or get a case with reinforced buttons (they make it easier to press).
bigxie's rom also does it, there's probably several others
We are not including volume wake in our rom. We got a resounding HELL NO when we asked folks if they wanted it. The power button is just as sturdy as the volume. If its going to break, extra stress will do the same to volume as well.
The nexus one button failure has no relation since its a completely different manufacturer using different cluck mechanism etc. So really this thread is about power button failure in general. I think it will be fine.

But at least you have the option of pressing 3 buttons to wake the phone instead of 1. That alone cuts down the chances of it failing by approximately 67% right?

Are you going to consciously alternate using each one at different times?
The thought never entered my mind. These are expensive devices and if there's a manufacturer defect then I'll simply take it back. Having said that, I've never had a hardware issue with any of my Android devices, no dust under the screen or anything weird. But if I did, I'd take it back immediately.
Would be nice to have the option in the menu, but leave the default to off but allow users to enable it as they please. I subconsciously think about this as well, perhaps because the button is so small it does not install much confidence in me.
That's one of the things I miss on my SG2 is the front centre home button as an extra option aside from the power button to wake the phone.
Perhaps down the road they'll manufacture smartphones with capacitative power and volume "buttons" as well?
This would suck. I had the power button break on my nexus s and I baby all my phones. I'll be depressed if my $600 phone breaks for no reason.

I only heard one person personally and none on here that suffered from the power button issue. From what I heard the nexus one was more prone to it. I had 3 nexus ones and never had that issue. Also with this device I noticed that my button is keeping its springyness. Especially with the new touch recovery. I don't really have a reason to use the power button.

It's actually less of making the cable loose, and more about the friction from the plastic on the track. Every time you slide out your game pad, you are fraying the cable a bit. After time, your phone gets that white screen.

my R800at did the same thing . white weird screen but still operates fine. i ordered the ribbon and yes installed correctly. same problem it didnt fix it. i too installed a custom rom and it went white shortly after. im just asking someone to think out of the box on this one. i love the work you do here saved my butt a hundred times. i inspected both cables and even sent my old one back in my return package and got a refund . It looked like the other no fraying or any unexpected wear and tear.

Phone won't boot, did I just mess it up?

Alright so this isn't anything related to mods at all. It's the phone itself.
So I was going to play some Dead Trigger, nothing big, minding my own business. I slide up the screen to put my fingers on the gaming buttons. After a while the phone got hot (as usual), so I decided to turn off the game and slide down the screen.
This is where it happened. The screen got stuck halfway, so I slide it back up again to check behind it.
This little thing was pulled down:

See that little square in the red circle? You might be thinking: "But that's normal!".
Well I had this case of slightly broken phone. I got it from a friend that had a skating accident with it so it was pulled up all the time.
So I'm thinking that's what stuck it, and tried to slide the screen down again, but instead of the screen getting stuck I hear a loud CLICK and the screen turned off.
And not from the circuit board but rather like the kind of click that you hear when breaking a glowstick. I couldn't turn the phone on so I took the battery out, put it in again and tried to turn it on.
The vibration that activates when you turn it on worked like normal, but then nothing else. The screen doesn't turn on at all, nor does it properly boot either I think. When I plug it in my computer I hear the windows "device connected" sound, but I can't access it.
So what do you guys think? Is it fixable? Did I just royally **** it up?
Feel free to ask if you find my explanation confusing.

Sounds like the flex cable got stuck and snapped - had a similar thing happen on my g1. It's a royal pain to replace from what I've read, but is relatively cheap and there's no harm in trying to repair it i guess.

Power button issues

So, I know our phones are getting old, but I was wondering if anyone has experienced issues with, shall we say, an itchy power button? I was having some stability issues with my GS3. Some issues were clearly software-related, so I wiped and started fresh with new firmware and a fresh ROM (running AICP). However, during the process, I removed the phone from the case (Otterbox commuter case) and noticed that the power button is a little wiggly and super sensitive, and sometimes doesn't "unpress" after I use it to shut off the screen and lock the phone, causing a forced reboot and problems getting it to fire up again. Also causes issues trying to force the phone to restart into download and/or recovery and instead sometimes bootloops because the button is still activated/"pressed". Pretty much any time I (or my pants pocket) touch the power button, it powers down and I have to gingerly restart and pull on the rubber button on the case to keep it from a boot loop.
Anyone have any ideas? I know the phone is old and probably not worth paying for a repair, but I can't afford a new phone and with lollipop it's otherwise still running pretty well. I'm trying to access the power menu from the dropdown instead of actually using the physical button, and using the home button to wake the phone, but it's freakin' annoying when the phone shuts down in my pocket and I don't realize it.

So, I know our phones are getting old, but I was wondering if anyone has experienced issues with, shall we say, an itchy power button? I was having some stability issues with my GS3. Some issues were clearly software-related, so I wiped and started fresh with new firmware and a fresh ROM (running AICP). However, during the process, I removed the phone from the case (Otterbox commuter case) and noticed that the power button is a little wiggly and super sensitive, and sometimes doesn't "unpress" after I use it to shut off the screen and lock the phone, causing a forced reboot and problems getting it to fire up again.

When I had this problem with my S2 I users an app called Gravity Screen Off so that I didn't need to press the power button to turn the screen on and off, reducing the number of reboots from the power button sticking.

this happened to me and after much research online found something silly that actually worked for me. grab a pencil, hold a couple inches away from power button, and firmly tap the power button with the pencil eraser end like 15 times and it might re-align. this worked for me for awhile but dont hit it too hard and break it. and ur phone case could possibly be causing it to happen as mine was. i used a razor to cut out the area around power button to stop this from happening and it hasnt happened in about 6 months. woked for me but maybe not u. but its free to try. good luck and let me know if this worked for u too like it has many others including 2 of my friends.
Cleaned the actual power switch inside, but it seems to be the external power button, which is all jiggly and worn out. I just ordered new buttons for under $5 and will report back when they arrive, but I think this is just a situation where the physical button lacks the return spring strength needed to disengage from the switch underneath after being pressed. It's been hella annoying, but if all it takes is a button swap I'll be happy.
Button switch on the board is dead. I don't have the tools to soldier a new one on, so I cut off the bad one and have been running sans-physical button. I used download mode to fire it up again.
I ordered a new board for it and will replace when I decide it's time to sell the phone. Found a like-new clean one on Amazon for $28. Done.
