[Q] Has anyone replaced the lock button before? - LG Optimus 3D

My lock button is getting rather iffy and hard to press, I was wondering if anyone here has either swapped it out for a new one or if just opening and cleaning it would help.
Also I'm extremely familiar with working on cellphones just I have no idea if I'd have to find another phone to try and salvage a piece from since I haven't worked on an Optimus 3d yet.

I don't know about replacement/cleaning the button, but you should save it while you can.
For example, I use this app Turn Off The Screen to turn off and lock the screen. It's extremely light and simple.
Also, in the new firmwares (v30a and v30b) you can use the volume_down button to unlock.

Hadn't noticed that, I thought it was only available on CM based ROMs.
Thanks for telling me this.

Use TapTap app. Its great. It uses your proximity sensor to turn on screen. You can set it it up to how many times to tap on the proximity sensor. I saw a lot og peopple is complaining about the power-off button these months. Almost if it was programed to last around 18months. I didn't replace mine with a proper one. I soldered a button from an old nokia to the pcb. If anyone here from Serbia who has the same problem,please contact me so we could order together a power button flex cable together.

I tried that but in another phone . But generally it's cheap and just disconnect socket (I'm not sure about the word spell) then connect the new button with that socket ,, see youtube there is a complete video (of optimus 3D) on how to take it a parts .

Q: any ROMs capable of changing button commands?

So my phones power button recently stopped working (think its a spring or something but it fell into the phone and depressing it does nothing) and I was hoping that someone may know of any ROMs that may allow you to reset buttons so that say the volume down button allows me to wake the phone. Currently I can only wake the phone by receiving calls, plugging it in/unplugging or removing and replacing the battery. I am hoping that I will not have to take it to a repair shop or perform the repair it myself. Any help would be much appreciated.

The collective's Redemption can do this through the rom control feature. Their are probably other roms that can as well but I haven't used them.

HTC One X - Home Screen/Restart Issues

First off, apologies if these have been covered. I tried searching and couldn't find anything the same as what I am getting but it may be that it is buried in another thread.
Couple of issues with the One X
LOCK SCREEN RESTART
Most people will probably know already that holding the power button for long enough on the Lock Screen will restart the phone. To me, this is ridiculous. Having no kind of confirmation screen means that the phone is constantly restarting in my pocket as it presses against my leg.
Is there any way to disable this function?
HOME SCREEN NOT SAVING
I add the bookmarks widget to a home screen. It stays there nicely until my phone is restarted (usually due to the issue above). When the phone comes back on the widget is gone and an app (a different one each time) has been added instead.
Anyone else having this issue or know what may be causing it?
Again, sorry if these have been covered and thanks in advance for your help.
Haven't noticed the widget issue, but I don't use rhe bookmarks widget so maybe its specific to that particular widget.
But there have been a couple of times where I've had my phone in my pocket and pulled it out only to have it be turned off. Not sure why considering holding down the lock button on the lock screen is supposed to restart the phone, not turn it off completely.
Sent from my HTC One X using XDA
The home screen issue appears to have been fixed with the latest update.
The lock screen restart is still driving me mental though so if anyone knows of a way to stop it would be appreciated.

Re: the phone being off - i have the same problem. For me it seems to be a power issue - if i check the battery use stats, it's completely zeroed out. I'm still troubleshooting that issue.

1) get a case that either partially covers the power button or covers it completely but making it harder to press.
2) get a belt pouch
In either cases your phone will only benefit and may last longer
I personally use horizontal belt pouch and have access to the phone in any position I may be in without awkwardly stretching or leaning, well, unless I'm laying on left side...no issues with pressing buttons ever.
Hi all ,ive resurected this thread to see if anyone has found a way to stop the restart button from working when the phone is locked as its becoming a real pain,ive searched but not found anything....
bump,any ideas anyone, surely just software ? ....
I secomd that.
I've had the same problem from the start. The One X is too easy to unlock. I got some relief with Widget Locker by allowing me to disable the notification bar as a method of unlocking but I still get regular restarts when phone in my pocket and press against power button. Restart should be restricted to an unlocked screen...just like my original HTC Desire. Why do some phone features go backwards?

The restart feature is there to force the phone to restart should it become unresponsive. It's a handy feature to have, it's essential, it's not backwards. Buy a case that limits your access to the power button and hey presto, problem solved.

Yeah If the phone froze on the lockscreen and the power button didn't work when the phone was locked there would be absolutely no way to recover it since it doesn't have a removable battery. The only solution is buy a case the makes the button harder to press or don't carry it in your pocket.
Sent from Xparent Red using my Venomized Evita
Okay got the picture......reluctantly I will need to buy a case..........Can I make a suggestion for future HTC models.....have a reset button in the form of a tiny hole-identical to the SIM eject hole but obvious on another side of the phone so as not to get them mixed up. This will satisfy everyone.
That's a great suggestion, but I highly doubt it will ever be implemented by HTC. They save money on manufacturing by having the power button doing this operation.

Anyone finding their power button mashed down?

I've had my One S since it's come out, always keep in a case and I've noticed it's been harder and harder to push the power button down to wake it up.
I see Expansys has a replacement sim cover here http://www.expansys-usa.com/htc-one..._productfeed&gclid=COvFrtXItbACFUMCQAodJx8-7g
This should include the power button mechanism but I'm not sure if I'm ready to spend $20.
And I certainly don't want to go through the hassle of a replacement from TMO.
Anyone else having issues? Are there possible solutions?
I dont know if there are any solutions, but I notice a difference too from when i first got it to now.
I had the same problem occur to me on the HTC Sensation.
Might just be wear and tear from how much you keep on pressing the button. A solution to slow down this 'wear and tear' would be to unlock the phone by means of the softkeys or volumekeys.
Just to add gas to the starting flame: the Nexus 1 had massive widespread power button failures...
how do you unlock from the volumerocker or soft keys?

The Sensation had a feature in some custom ROMs called Swipe-to-unlock, basically you swipe your finger across the softkeys and the screen turns on. Swipe the other way to turn it off.
But I'm not sure if this is also on One S ROMs
i had to exchange 4 of them for various reasons and only my last unit has a perfect power button that still works as new. but it would be great to have swipe-to-unlock just because how tall this phone is.

Yep, Swipe-to-Unlock is a great option! Hope to get it for our One S soon, and as sources are released, we'll probably get this option with some custom Kernels or additions...
Don't know if a "soft" solution is really good, but it will eat some battery for sure as the system is "waiting to be touched" and not really sleeping as it should be. Some has huge drain, some not... But I didn't test all these options, and not sure that they work with our phone.
Another popular solution for the sensation was using the Volume + button hack to wake the device.
I never had that issue with my sensation and after one month with the ONE S my power button still works fine.
(On his sensation) A friend of mine placed a small piece of paper under the power button to raise it and it seemed to work for him, maybe you can try something similar?

Lock button problem.

Hello, I'm having the famous Cappy lock button problem (the one where said button doesn't work). It's not a physical problem (unless a contact has died somewhere on my motherboard) because my button feels the same as it did the day I got this phone. I've also never had any kind of problem with my power button before. I did get my phone secondhand from a friend which voided the warranty. The only way I can turn the screen on is by plugging it in or removing and replacing the battery. The only way it turns off is by timing out.
Help guys, I need some answers!
Thanks in advance.
P.S. I already tried the camera app trick and to no avail. I also can't do anything in recovery mode because the power button is also the selection button.
My button started acting up. I used a can of compressed air to spray into the edges of the button, and it's been working great ever since.

This is All very helpful, but I don't think that it is a hardware issue. I'll try all these things that you have suggested and we'll see to certain.
When you take the battery out then put it back in does it automatically turn on? If so the power button needs to be replaced....at least that's what mine and a lot of others I've seen was doing.

I took it apart and the motherboard was surprisingly clean. I was expecting it to be dustier, but everything looked fine. I'm now thinking it could be a micro-fracture on a solder contact. I still haven't sprayed keyboard cleaner directly on the button, so maybe I don't have to buy a whole new motherboard.

Did you replace the button yourself? I have been without my lock button for about a year now and I have kind of gotten used to it, but if the process of replacing it is fairly simple than I may just do that myself! Also where did you purchase your new lock button?

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).

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.
