Hi all,
My wife's G3 power button isn't working. The volume buttons are though which I find a bit odd. In order to turn on the phone you have to plug it in and unplug it during the battery load process to turn it on. I saw a couple other similar threads on this but the lg pc suite didn't work
I did open up the phone and replace the screen. I have also cleaned the contacts and used my power button (I have a G3 as well) to try to fix hers and it didn't work which seems like it could be a software issue or something that isn't connected properly inside the phone itself.
Any ideas?
Hardware
I think you have similar problem like I have . If you opened the phone in that area where the camera is(the front camera flex cable), there are small , very small parts , in my case I wasn't carefuly and one is now missing when I tried to take of the front camera ,I broke one just one little piece(very little) AND THE VOLUME DOWN is not working anymore .Take a look if you have all that parts. And if you are also missing one that's the similar damage. Micro soldering could help in your case. Sorry for my english.

I have a problem with the power button on my desire, the phone wont switch on.
I have taken the phone apart but cant see any physical problem.
The phone still charges ok.
Is there anyway to get a stock phone powered on without the power button.
Does it sound like it might be a faulty flexi cable.
Or any other advise.
you might need to take phone to repair center sounds like something a phone repair ceter can fix , i dont think there is a way of turning on the device with any other button ( i think it's possible if you changed it if you rooted but in your case i dont think so) does the cable near the power button look burnt out or loose , did you drop your phone ?
btw what are your usage patterns ?

The power button is hardwired. You can change the function of hardwired buttons using software, but software needs to be running/on to do that. You cannot use software to redirect the function of a hardware button with the software not running/off.
I have managed to switch the phone on using the usb trick, and the power button is working. Guess i will be ordering a new flexi cable
sounds like you need a new device
Hello everybody! My htc desire's physical buttons(actually just the volume up, home and menu keys) don't work...I press them but nothing happens. Well, they work sometimes, but when they don't I reboot my phone, randomly press some buttons, and they start working again. I just don't know what the fault is. Im on MildWild CM 4.3. I think the same problem was with other firmwares too. Can you please solve my problem?
If your device is under warrantly just send it to htc. It's a hardware problem, not something that you can solve with a script.
Ah, so you're telling me there's nothing that can be done to repair it? Cuz, my device isn't in warranty(I just replaced the casing)...

I don't know.. I don't want to be pessimistic, maybe you can search for similar problem in internet and a possibile solution, not just for Desire but in general for devices that have hardkeys. Maybe like use a spray for electric contacts while device is turn off and wait that it's completly dry before turn it on. Good luck.
I can't remember it, but I think that this problem appeared only after I got my casing changed. Could the technician have done something wrong? Can I send it to the man that changed the casing?
It's probably just some dust that gathered underneath the buttons. I had the same problem with the volume down button. I used a needle to clean the dust around it, and then it worked perfectly.
I dont think it could be due to the dust, cuz there are three buttons which simultaneously stop and start working... It's a bit strange tho..
I have issues now with my power button. It's unreliable... that is, the button sometimes works. Sometimes when I press it, it opens the shutdown menu..
Started all of a sudden. Not sure how that happened... and it's out of warrenty for 4 months now..
That is why I use Button Savior
Same!
I am getting the same problem. I have replaced the keypad flex with a new one and still getting the same issue. It would start working randomly like if I open the browser and open many tabs, then it would work. Funny thing is that they would not even work when I go in recovery.
My desire is 2yrs old now but I still love it.

Same problem here.
Mostly happens with Home and menù. Less often with volume buttons.
For now I'm using the "button saviour app" workaround, but if is something hardware I will know it very soon... (made a copy of my rom on a friend's HTC Desire)

All three buttons simultaneously! Buttons usually fail gradually one by one and drive you mad finally. I would put my money on the keypads being misaligned during whatever you got done with casing. Take it back to him.
If its some kind of misalignment no amount of sprays will help.
BTW I use zmooth for button conservation
use soft key instead

I had the same issues : menu button working randomly, had to press very strong on up/down volume buttons.
I've dismounted my phone (using this : http://www.formymobile.co.uk/desiredisassembly.php ), and I saw that there were a lot of dust, hairs.. I tried to clean up/down volume buttons the best way I could, and they both work so much better now! Not totally perfect though.
By the way, I noticed that there was a lot of compressed dust in micro-USB connector and was able to remove it fully (thing I couldn't do without dismounting phone).
I didn't want to go farther to access menu/home buttons because I didn't have time and Menu button works quite OK.
I have the same issue here with the volume buttons they tend to get unresponsive and unreliable.
Even though all the parts were renewed since six months ago, the volume buttons are probably bad designed?

You could replace bad working buttons' functions with others'. My volume down isn't working, so I made my search button act like a vol down.
Buy the new one

just removing the lcd flex cable doesnt solve the problem..do the process in three steps
step1: remove battery pin(inbuilt battery) or remove battery..then press the power button for 5seconds..and then putin the battery..
step2:remove the lcd flex cable and the touch equiliser pin also..remove the battery pin(if inbuilt battery)..or simply remove battery..do every thing in the same process..dont jumble..after doing that..again press the power button for 5 seconds again..and putin the battery
step3:now assemble the entire mobile again with screws..because there are certain connections with motherboard and screen which will come in contact only after placing them tightly with screws
now poweron the mobile..this time it works..
the main reason is the failure of inductor component on the mother board(cant tell the accurate component name)..

100% my very same problem
I can confirm this problem was fixed by this

But for god's sake, be careful with tinning. A drop too much and you have a shortcut.
EDIT: intriguingly, I noticed I have another close up photo of basically the same area (please, don't bother with oxidation trails).

The G3 just dropped down on the floor with the circle case. Then It was working some minutes apparently with no problem, until I myself turn the phone off and restart it. Then the device just didn't turn on. The only thing is that the screen is black and the led notification blinking green and blue
when i connect the charger, the red led blinks once and then disappears, then after 30 seconds the red led appears which apparently shows that the phone is charging the battery. Also When I connect the phone to the PC, a sound of connection is heard from PC but the PC doesn't complete the device recognition process as no new device is found.
I tried to make a hard reset, but nothing happens when I press the power and volume down keys. Tried some other tricks with the battery and the hard keys on the phone but no result at all, as the same story just repeats. Does anybody have a solution for the problem? This devise is the only android device I have
Help
Please Help :crying:

Did you do anything else after/during the time that the phone was off? And is there no possibility that you cracked the LCD digitizer? I mean it might sound strange but this is what I had with my old phone. I dropped it, nothing serious but then I put it in my pocket and upon taking it out I noticed the screen not turning on. As stated above, my digitizer was broken and multiple people told me that the digitizer had a small crack which I didn't notice, then when I put it in my pocket I put too much pressure on the digitizer cracking it. The LED-light did work though, and this sounds very similar so my advise going to the store and asking wether they know what the problem might be.
(Hopefully this was helpfull hehe)

If you Don't see the LG splash screen when pressing the power button it seems like a screen or digitizer problem for sure.
BUT;
after you try turning it "on" let it sit a few minutes and see if you can call your self or send a text to see if it makes noise vibrates etc. to confirm a screen problem.
OR
Also you can try putting it into download mode.
Battery pull (don't turn on)
plug USB into phone but not computer
Hold volume down AND then plug usb into computer
if this comes up to a pic of something on the phone it will be software related. to get out of this mode you can do a battery pull.
Remember to always read up on topics and things you are doing. There are guides here on XDA to help you out.
Hope you get your phone working

I didn't do anything special after/during the time the phone was off. I checked the screen very carefully under a lamp. No particular sign of crack. Thank you very much for sharing ur experience.:good:

Hope you fix your phone fast
Yeah... Probably it's a hardware problem. Someone who checked the phone in order to fix it, said that the problem had been with the device board. Even though I was satisfied with the phone, I have found out that the G3 is a sensitive device, as the height of the table from which it dropped down wasn't too much. So always take care of your G3 phone.
Basically, I changed my broken screen (LCD + digitizer) with a new one without the frame. After reassembling the phone, the power button refuses to turn on the phone (it is completely unresponsive). When I plug in the charger, the phone charges, and I can also access the fastboot menu if I hold vol - when plugging in the charger. Both volume buttons are working, the screen and charging port is functional (battery appears to be fully charged as well) so I have no idea why this happened or how to fix it. Has this happened to anyone else? It appears to be a hardware problem (I think) but I really need help from anyone who knows how to fix this problem. The phone was working fine before the screen replacement so I'm not sure what could have gone wrong, please help.

I don't think anyone can help you with a hardware problem. I have a software fix that can give you a invisible softkey power button. One SystemUI.apk should put it in the far upper right hand side of the statusbar, the other on the far right hand side of the navbar.

Thanks very much. Well the help I'm looking for is to if anyone else experienced this problem and how they got it fixed.
Edit: well I got the phone to start up, I booted it from fastboot (via a pc). I downloaded the apps and tried installing them but it kept saying they were corrupted and could not be installed, do I need root access?
Hello Propaway did you manage to get your power button fixed? I'm having the exact same problem right now

The power button on the board itself seemed broken. I ended up using an app to reroute the power button's function to one of the volume buttons. As with getting the phone itself on, I used fastboot to power on the phone. Have you managed to fix yours?
