New issue? On/Off button seam to "flicker"?

Hey ya all
Ive tried to google for this issue but haven't found anything. I got it yesterday evening, about 1-2 hours after OTA update to 2.3.4.
So what happens is when I hit the on/off button to turn of the screen, it sometimes goes black for about half a second and then turns back on. Same when I try to wake it, goes light and then goes dark. So it seams like a dubbleclick almost.
Sometimes I've also got the issue that my Home button just keeps making screen shots, took me a while to figure out thats conected to the power button. How am I supposed to take a screenshot? Could it be a simple hardware issue where the button gets stuck? I've tried to remove the backcover and clean up, but it all seams fine for my untrained eye.

How are you holding the phone when this happens? This same thing happens to me sometimes if I kind of wrap my hand around it when I pick it up. I unconsciously hit the volume button like half a second before I hit the power button, and the volume button wakes the phone & then the power button turns it right back off.

It can happen whatever way Im holding it im afraid, and it has only occured since last night. Lets see if someone else got this after 2.3.4 or if its just a wierd coincidence.
And also, as I said, it seam to bug out my screenshot function.

That's not a coincidence, happens to me as well.
My guess is that's because of the new screenshot feature (hold Power+Home). Can anyone hazard a guess as to how to turn it off?

Well, guess it's a good thing it aint then, hopefully it'll get fixed.

No one else with this issue? It anoyys me alot

I have this issue, but it only happens if I press the button too fast or something. I don't know how to explain.

happens to me too

Randomly enough, just tried the screenshot function and it said saved to Camera folder but it's not there. What app is used to take it? Someone said it was MySketcher but I don't know

I spoke to HTC support sweden today and they didnt seam to be aware of this issue atleast. Keeps happening to me about 30% of the times i hit the button.. I dont think its hardware issue but didnt care to factory reset the phone yet.. Anyone of you with the issue has other than stock rom? Did it only happen after you upgraded to latest firmware? Ive only had it since 2.3.4.

I'm getting this exact same issue since upgrading to 2.3.4. I have a stock ROM too. It's really annoying, press the on/off button and it doesnt always turn it off, it does exactly the same as what the op says.
Also getting it take screen shots when I press the home button.

Was abit tricky to understand you, well anyway, so you had it repaired then? Id love to avoid that, hate being without the phone. But maybe thats the only solution.
Thanks for your input.

Yea I'm not so sure if this is a software thing. I haven't experienced this during regular use, but I have experienced a double-press effect while in Clockwork Mod. If I press the button on the leftmost part and do it slowly, I can get a double click without actually clicking it twice. Scares the crap out of me when I'm flashing roms and kernels.
So maybe something is up with the power button itself? Too sensitive maybe?

same issue here, was afraid it was my button. first i thought it was crt animations that were causting it. i have to go in to build.prop and turn off power+home screen shots because half the time i hit home it take a screenshot. not sure what's up with the power button.
have the issue on both bulletproof and eaglesblood, both 2.3.4

Happens to me as well and drives me absolutely insane.. The problem is definitely hardware.. I got a replacement back cover under warranty and after two weeks the problem is back just as bad.
To somewhat remedy the screen off/on flicker, i use 'screen off and lock' for long press of search button.. Not the same I know, but at least it doesn't flicker back on.
As for recovery, you can use home/menu for up/down, back for back and search for select.. I find this light years easier than having to ninja push the power button to avoid a double press.
I wish there was some way to fix the damn button tho.. I don't understand how HTC screwed it up so bad.

Having the same problem. Is the problem with the back cover or the phone itself? I looked at the button underneath the case and it looks bent. I was thinking maybe a tiny piece of paper inside would help, if it does, I'll report back
EDIT: playing with the button with the case off shows no problem. It has to be the way the case interacts with the button
EDIT 2: A piece of paper doesn't completely relieve the problem but does make it much harder to reproduce, and in my opinion, it's much nicer to press now
EDIT 3: Thicker paper=issue solved. I'll send HTC an email about it not reaching the button all the way, maybe they can do a recall on affected backings

I ripped off a little piece of paper from a paper cd case about the width of the button inside, I then folded it until I found the perfect thickness and set it on top. I just carefully put the backing back on. It pushes the power button up about double what it was. I'd take pics but all it is is a piece of paper sitting on top XD

Power button hardware issue!

Haven't seen this one anywhere here on XDA yet, but I did find one other person through google that has my same issue. So, here is the problem, when you slightly press on the screen just below where the power button is, either the screen turns off or the power menu comes up. This just happens to be exactly where I put my thumb when holding the tablet, so I constantly get the power menu or turn off the screen on accident. This is an extremely frustrating problem, it happens non-stop right now. I've also noticed that the power button itself is messed up too, in that I don't even have to push it. If i just barely touch it with my finger it turns off the screen, it's like the button is stuck. Of course, I have already unlocked so getting a warranty replacement is out of the question. Just wanted to put this problem out there so other people know about it.
PS. anyone know of an app that will disable the power button? If not, I guess I'll open it up can physically disconnect it or something, just make sure it never gets turned off!, lol

How would you implement it?

how are you going to turn it on/off if you disable that button?

Well, I seem to have fixed it for now. The power button is actually three pieces, the plastic button, a small sticker with a tiny piece of foil on it, and a tiny contactor on the circuit board. The button pushes down on the foil, and this connects the two piece contact on the circuit board together to complete the circuit. It looks like the piece with the foil was too tight over the contact on the board, so anytime any pressure was put on it in the area of the power button, it would make the connection. I simply pulled the foil piece off (the sticker), and stuck it back on, but more loosely than before. For now everything works correctly with no accidental power button pushes. However, all the little plastic tabs that hold the back on the tablet are apparently one time use, because they are all broken now, and the back is barely hanging on. Guess it's time to find a case that I can use with the dock so I don't lose the back off this thing!

i727 skyrocket stuck in continous reboot loop and doesnt get past start screen

I I have a Samsung Galaxy S2 Skyrocket i727 (with stock firmware and ROM), i dont have a SD card and not too many apps installed either, maybe 10-15 apps at most. Today while the phone was in my pocket it just went into this continous reboot cycle, it reboots, gets to the AT&T splash screen and then reboots again and then this goes on forever.
I googled the hell out of this issue but cant seem to find a solid solution and hence hoping u guys can help.
I cannot get into recovery mode cause it never gets past the splash screen
I cannot seems to perform a hard reset (power button + volume key) , it just reboots again.
I tried plugging the phone and connecting via USB but it doesnt help either, it reboots before the computer can detect the phone.
Hope u guys can help ? life without android is no fun...

I had this same issue with my LG Phoenix, I tried the needle around the power button, and that popped it back to normal. Apparently I held the button down to a side and it got stuck even though the actual button part was in it's "normal," position.
However it did reboot several more times after I got it unstuck. I did remove the back & battery, & unplugged it. Let it sit for a few minutes, after that I put the USB cable back in, then pressed the power button, put the battery back in and pressed the button again, and it went through the normal reboot process.

Just wanted to give you guys an update that i started cleaning the part around the edges as some folks suggested and that failed. then tried smacking around and blowing air into and that failed. Then took the entire phone apart and cleaned it several times using different techniques and sad to say that it all failed and i m SOL.
Bummer but it is what it is and i was quiet happy with that phone.

Where does one find a power button for the skyrocket (the one attached to the motherboard)? The closest thing I could find was this:
http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-ii-skyrocket-power-button-repair/
It is a repair service though and I live in Canada, I would prefer if I could just order that part. I have been to few repair shops that cant do anything because this power button is hard to find. I opened up the motherboard and the power button clicks fine, so I think it probably has to be replaced.

Freezing the phone
I had the same issue, came here and read all the things about the stuck power button and needing to replace whatever is beneath it. My friend works in aerospace and had told me about one of the things they need to worry about is temperature causing wire shrinkage due to temperature. For whatever reason, I decided to use that logic and throw my phone in the freezer wrapped in a dry rag. 30min later and the phone finally worked after 8 hours of the boot loop/no boot. That was around November and I haven't had an issue with it since (until today, but it is a different issue).

can any one else confirm this? my phone keeps shutting off. when the screen is black, itll vibrate every second. im assuming its another stuck power button.

I have just fixed mine!!!!
There is a little battery on the circuit board when you take apart the phone. It looks like a small watch battery. Top side is and bottom side are opposite polarities.
I had the exact same symptom. Sometimes just pressing the power button momentarily would bring up the power down menu, then I knew to press it a bunch of times because it was stick. If I didn't eventually it would turn off and vibrate constantly. It kept getting worse.
I measured with an ohm meter and the button itself seems fine so I figured maybe the digital logic relating to the button itself is faulty. So I shorted the little battery on the board (do this only for a brief period, no more than 1s) and put it back together.
Its behaving perfectly normally. I was also getting weird artifacts during video playback before, kind of like what failing solder would do on a bga gpu. It fixed that too.
So I think its similar to that problem some laptops have, where it wont turn on until you remove the battery, hold the power button down a couple times, and then plug it in. It seems a complete circuit discharge fixed this problem at least for me.
If people are interested I can try to find a picture
removed link
In that picture its the silver shiny metal circle. To short it you connect the bottom soldered part to the metal plate on top of the battery. This comlpetely drains all circuits.
So I think a lot of these problems are caused by a phantom charge. In any sense, Im very very happy
Also this could explain why the fridge method worked. Cooling the battery can significantly drop its charge, however I would advise against the cooling method if possible.
EDIT: blah cant post links... if anyone needs the image pm me your email

You'd need to find a friend or local electronics repair shop, but I ordered some here:
http://www.etradesupply.com/oem-samsung-galaxy-s-ii-skyrocket-sgh-i727-power-button.html.
The buttons are $0.99 USD if you buy 2 or more ($1.05 CAD), but 5-7 day business shipping is like $16.99. Still cheaper than a replacement phone, and it's an easy fix for an electronics person or electronics/tv/computer repair shop... At the rate these power buttons have had reported failures, and for the price, I'd get a couple of them in case the replacement fails in the future...
If my wife keeps squeezing the power button on her phone when some crappy app she has wigs out, I'll be needing my second button sooner rather than later...

why when one person says it something everyone band wagons on that idea. i actually had the same issue my skyrocket couldn't go pass the "samsung" screen. all i did was flash a new rom or i just restored an old backup

Then it was user error or a bad flash. And that's software, not hardware.
Skyrocket power buttons are known to fail. I believe Samsung has even acknowledged this.
When your phone randomly goes into a 1-second vibration cycle, sometimes showing the reboot menu beforehand without pressing the button, more than likely it's the power button that has either failed or is sticking.
With my wife's phone, the button was not sticking, and usually lightly tapping the phone at the right angle on your lap or the counter would break the vibration cycle and let it boot up, until the next random power button press and vib cycle would happen.
Button replaced, same exact ROM, and problem gone. :thumbup:

I have a repair shop and i fix these issues with no problem. the only issue im located in Puerto Rico. when the power button gets stuck is because of heavy use, a fall or something that makes a lot of pressure to it and the copper contacts inside the button stay making contact. this is know to happen to i727-i717-i997-i897 and some other galaxy s1 s2 models.
i attached the picture of the power button.

[Q] The Notorious Power Button Problem

Hi all, so many of you are probably familiar with the power button issue on our Infuse. I have searched on every forum and have done every possible thing except soldering cause I don't trust myself with that. But before anything else, let me tell you what all I've done.
I have removed the back, and the power button and put in my battery, so the power button isnt even holding anything down. I even checked the little white clicker thing that gets pushed in, and it was not pushed in. So I figured it must be on the motherboard.
I stripped the motherboard, picked it up, blew everywhere around it as hard as I could for about 5 minutes, then screwed it all back in. Then again, still not even having the button attached, it did it's normal bootloop.
I have tried everything, from chucking my phone across the room, to removing the power button and putting it back in after cleaning it, to blowing on the motherboard. Have I missed anything? Am I done for good?

Over time the power button can get in a state that it is always on, regardless of outward appearances.
Try spraying gently with CRC electronics cleaner while working the button then allowing to dry before reassembly of phone.
If this doesn't do it, mobiletechvideos.com can replace the button for approx. $35-40.

Nexus 5 Bootloop - can't even pass bootloader screen

Hi All!
Today is a very unfortunate day for me.
I was viewing whatsapp and all of a sudden my phone turned off, turned back on and it has been rebooting ever since.
I have tried all possible troubleshooting steps to see why it is happening but I can't even get into other screens like recovery, bootloader because it restarts right away.
Had a chat with Google and they wanted me to send my old phone and place a hold in my credit card -blablabla.
Obviously when they receive my defective Nexus, they will see the bootloader screen with an UNLOCKED icon.
That will be bad for me - because they could charge me money for a new device (the one they are sending ahead).
I would rather wait for the Nexus 6 instead of repaying for my defective 5.
Is there a way to maybe force it to be locked again before I send it in?
I have one of those JTAG connectors and I was just wondering if it will make any sense if I try that.
Any help would be greatly appreciated.

It sounds like your power button is stuck. Mash it a number of times and see if that frees it up.
Also, if you have a case take it off

Yup, seems to be an hardware problem with the power button.
By the way, if you can't fix it : Seems that Google doesn't care about unlocked bootloader if it's an hardware fault

I actually initially though it was the power button so I removed the case check and mashed it a lot but how it turns of turns ON doesn't make sense because if the power button is stuck usually you have to wait 3-4 seconds before it turns off.
The behavior is like this - Google Splash screen, 1 second pause, vibrate, turn off - Google Slash Screen, 1 second pause - NON stop.
Still it could be possible but I'm hoping they wont charge me anything if they send me a new phone. I would rather wait for the Nexus 6.
They actually asked me if I was rooted and I said NO. There was a chat log on it. Oh well.

I had a similar problem and I think it was the power button as well. I RMA'd it but I kept smacking the crap out of the back of the phone and around the area of the power button. I noticed it'd start getting further through the boot process and eventually I was able to get it to boot all the way through and actually stay. I guess I smacked it hard enough to knock out the button, but I still went with the RMA anyways.
Maybe try smacking it around and see if it stays on longer?

I think you are all right. Now that I got home and observed it more. It is a stuck power button! I'll try to smack around it and have the bootloader locked in again and RMA it.
Do you think once they see it is being rooted, they will void the warranty even though it is obviously a power button issue?
