HELP!!! My MDA3's Power Button is COMPLETELY INOPERATIVE!!!!

Hi,
My MDA3's power button (on/off) stopped working!! Pressing the button does NOTHING!!! I had locked all keys except the power button, since the power button stopped working, the ONLY way i could turn device on was resetting it!!!!
I have tried upgrading ROM etc, but the power button still wont work!
Can anyone please help me with this?

How did you enter bootloader to flash the rom, is the power button not needed on the mda3 to enter bootloader.?

....
interestingly enough i was able to reset the device by just using the reset pinhole, even the hard reset they say by using recorder+power+reset i was able to do with out the power.

It sounds like you have a hardware problem rather than software, I'd send it back & get it swapped before the warranty runs out if I were you.
We've had four units fail with dodgy buttons, you might even find that it's one the other buttons that is stuck in the pressed position thereby preventing use of the power button (try the sound recorder/camera buttons).

..
I was able to fix this problem by opening the phone, cleaning it with compressed air and putting it back together. I suspect this fixed the stuck button somehow.

I had simmilar problem. There must have been garbage in the button, as I noticed that it did not have the same 'click' feel to it when it stopped working. Luckily my phone was still under warranty, and I swapped it out (ugh)

[solved] turn on the screen from black

Hi there guys,
i want to ask u if u know a way to remap physical key on galaxy nexus or another way to turn on from "standby" the cell without always pressing the power button...
i can think that fast it will be insible to touch after long use or continuisly press
thanks for your answer and tips about it

I'm not entirely sure what your asking. There are only 3 physical keys on the device and one of them needs to be used as the power button. If you mean turning the screen on by pressing the screen, this wouldn't make much sense as the screen needs to be on to detect touch.

only 2 physical keys...
1)power on/off button
2)volume
when the screen is black i can turn it on only by pressing the power button, i'm looking for another way to turn the screen on, ex. shacking the phone, pressing the screen, pressing volume key or etc...

The volume consists of 2 physical buttons...
All sensors are off by default when the screen is off. Turning these on would drain your battery dramatically.
If you were to change your power on button to one of your volume keys, what would be the point? You'd just lose the ability to change your volume easily and have a useless power button.

remap the volume key was just an example...
the matter is: is there any other way to turn on the screen without press the power button? with the constantly and massive use of it, it will become fragile and easy to break out.

i use volume up/down and power on /off randomly, all are enabled to wake up the device on aokp milestone 4. i think they may have designed the buttons to survive for quite some time since there is only 1 regular button for the job. other buttons on other phones dont just die and break out do they?
edit: by enabled i meant it is possible to select them as usable. stock doesnt have it afaik (didnt have stock long enough to find out)

no, its an option in the Rom Controls under the lockscreen options menu.

Glados kernel has a touch wake option. You can set it for any length of time after the screen goes off. This will also prevent your phone from going into deep sleep so it can affect your battery.

yes and this is the problem, my experience with other phones with "one function key" usually they break out "easily"
ok so from what u all wrote guys my only option is to root the phone and install a new rom with that "touch screen option"
can u indicate to me better where i can find the roms you are talking about? i'll appreciate it a lot

Powerbutton

Seems like I have a problem with my power button.
It seems to be depressed all the time.
Can not turn off / lock the screen, nor unlock.
After I took the battery out and put it back in turn on the phone by itself.
If I go into the boot, I can not use the volume keys to change choices.
I restart in recovery so I can go up / down the menu using the volume buttons, but do not make any choice with power button.
Is it hardware failure?
Anybody had similar problems?

Had the exact same issue on my Nexus S. 100% the same. I was also unable to re lock my boot loader cause of it due to being unable to flash, navigate or use adb due to the button being "pressed" all the time. Brought it to Samsung and they replaced the button sensor. It was 100% hardware as yours is too if your phone boots when you put the battery in (before the os even boots). Warranty time my friend. Samsung makes awesome phones with **** power buttons

[Q] Sensitive Power button and reboot problems

My S3 started randomly rebooting yesterday. The power button also because super sensitive. Just a light brush would cause the phone to register a press.
I edited my .kl files and disabled the power button and remapped it to the volume down button. I haven't had as many problems as I did yesterday but now it shuts down when I plug in the usb cord and it did shut down one more time when I picked it up off my desk.
I thought it was a faulty power button that was causing my phone to reboot but now I'm not so sure. Remapping seems to have helped a little though.
The files I edited were sec_keys.kl and sec_powerkey.kl. For both I disabled key 116 POWER WAKE and remapped it to key 114 which is the volume down key.
Any ideas on how to fix this completely? Is there another power setting I'm missing? I'm 3 months from my upgrade and don't really want to spend cash on this thing.

The power button is a somewhat common issue. Look at some disassembly videos. Maybe you can find a way rig it or replace it. The parts are pretty cheap if youre willing to attempt it.

I think I have mostly solved my issues. I pulled out the power button and I haven't had a problem since. Between that , the remapped power key and the Auto Screen On app I think I can make it till upgrade time.

Power Button broker - how to boot the phone?

Hi,
unfortunately the power button of my nexus seems to be broken... so when the battery drains, I am not able to switch the phone back on.
Is there any solution to that?
I found this app that I haven't tested yet
https://play.google.com/store/apps/details?id=com.teliapp.powervolume
Is there a way to power up the phone anyway?
E.g. maybe by attaching the charging cable and remove battery? Is there a way to automatically power the phone up?
I installed CyanogenMod 12.1 from here http://forum.xda-developers.com/galaxy-nexus/development/cyanogenmod-12-beta-builds-t2958865 ... maybe is there an option in CM12.1 to enable power up by volume buttons instead that the default power button?
Thanks a lot for your help.

There are many ways in which u can boot in android with out Power Button.
1: Add a Schedule to phone when to turn on automatically.
2: Remap Power Button to other Volume Button.
3: Try Using Adb. This might not work, but may be try once. use "fastboot continue" command in adb.
