Power on / off button problem - LG Optimus 2x

Hello guys,
A few weeks ago I bought a p990. Everything is ok I enjoy the phone ( CM 7.2 rooted ) however the power button doesn't work perfectly . I have to tap it on the left side of button ( stronger than usually ). Do you know what should I do ? Can I change a ' wake up ' button for another ?
PS. i dont have warranty.
Please give me an advice.

HI, you can change a "wake up" button for another in settings-display and check "Volume rocker wake". You can after wake up screen with vol+/- button. :cyclops:
Try CM10... It's the best and the last night today's version is really stable and ****ing smooth...:laugh:

If you want stay on CM7 try reinstall your ROM and in CWM make Dalvik Cache and Format your phone. You will have clear phone and everything should be allright... Don't forget backup your data...!!!

Its not working at all Only first wake up work correctly. Then volume +/- doesnt respond.

the volume rocker wake works for me only when charging.. if the phone is off the charger nothing happens. Can you confirms it works for you even off the charger or after deep sleep ?

You must flash cm7 or cm10. There is a function to wake up your phone with volume buttons. And for screen off are tons of applications in play store.

Yup I think it's like that for everyone... when the power button dies it's time to buy a new phone... sadly...

Not true,you can easy change only power button switch and it's maybe 10 dollars expense

Most problem with LG mobiles is with power button not only me so many are facing power button problem :thumbdown:

Reminds me of a problem with the Palm T|X, which was known for failing power buttons (I wonder how many people remember that device? I am still using mine... ) The best and cheapest solution was the same -- just to replace the button. Doesn't even have to be exactly the same type, as long as it fits...

Yes i am from the ones that started to experience button problem but i found replacement and will replace it when it comes
After so many presses it start's not 2 work on soft press

There is any guide on how to fix or replace the power button ?

This same thing happened to mine. Sadly, a handful of roms later I am positive its the button itself. It works sometimes but not all the time. Having the option to set unlock to the volume rockers has been a lifesaver in CM.
Let us know what you find out.
using volume up is a temp fix, i did it also, had no other way, and using the tap tap app also works, what bothers me is, when phone shuts it self down, wich it does a lot all my android phones from stock have done that, the sporadically shut down thingie...how will i turn it on having no power button ?

[Q] Dead Power button after washing

Hi,
Every couple of weeks I give my Xperia Z a wash, this has turned out to be a bad idea. 2 days ago I washed the phone, held it under a running tap for 20 seconds, and now the power button does not work.
Luckily I can unlock the phone using the volume button and I can activate lock screen via a widget. Now I have to send it back to Sony for repair and I am running CM10.2, do you think that I should revert to stock ROM? If so, how would you revert to stock with no power button...
Any advice gratefully received.

Hi,
I am using CM10.2
I press the volume button and it activates the screen, then I unlock.
Update!
The phone switches itself on, so I guess the power button is constantly being pressed? Luckily I have been able to use Flashtool to revert to stock, now I just have to wait for Sony support to get back to me for the repair.
Next time use another detergent

I just tried that, and it looks ridiculous. But! It didn't work...
I also left it on a dehumidifier over night on full blast, no luck. Just waiting on Sony now.

my workarround > install carbon rom 4.2.2 disable powerbutton with root browser

disable the powerkey by placing "#"
"# key 116 POWER WAKE
reboot and the powerkey is disabled

Maybe for you, but in my case, it is generally stuck on. Yesterday it kept waking itself and bringing up the shut down dialogue. Volume up pressed rapidly in succession, also seemed to trigger the power button, which is how I managed to use recovery to install a stock ROM.
Lock the bootloader before sending the phone to service.

Wow, I would still expect a physical defect to be covered. Thanks for the heads up.
I unlocked mine in the early days before you could save your DRM keys. Do you think that I can still relock?

Yeah, no problem.
You just won't have DRM keys (obviously) and no Bravia Engine either.

Send my phone for repair and I just heared today it's covered by warranty, I had the device reverted from cm10.1 to stock and relocked the bootloader
So unlocking the bootloader does NOT break your warranty it only might give additional costs for replacing your nand or such to revert back to stock so to prevent getting those extra costs you simply have to revert your phone to stock firmware and relock the bootloader.
I had those extra costs on my Xperia S before btw, I did have a unlocked bootloader which I didn't relock :/
It might void your warranty if you have damaged any internal hardware like the cpu or nand, memory etc etc since they might not know for sure if it was the fault of custom software or a technical problem on their production side.
Keep in mind my Xperia Z was one of the first batch which had the dust issue on the camera, this might also be a reason why they repair/replace* my phone under warranty.
*No info on that yet.
Since you have no power button it might be tricky to enter fastboot, try using adb or booting into touch*recovery with a terminal command and then reboot from there into fastboot.
*touch is recommended since you can't select a option otherwise without a powerbutton LOL
Thanks, I will do that.

Done!
Thanks again for taking the time to assist guys.
Finally took the phone in, repaired within 5 days, and no awkward questions or costs.

Shortcut settings for Vibrate mode on lollipop

Ever since lollipop update, holding the power button and setting to vibrate/mute mode was removed. What do you guys do/use to go to vibrate mode now? Is there any faster way other than holding # on the keypad or changing to vibrate mode on notification bar that doesn't require to unlocking the phone.
Press volume down until the phone vibrates.

That's weird. I was rooted prior to the update. I wiped and flashed the stock rom via odin. Nothing else was done.
I don't use the stock lockscreen mainly because playstore lockscreens have more options like more apps besides camera and phone.
Try zuilocker. it includes a control panel with some quick settings like sound mode.
So, bottom line, on stock unrooted, there is no way to add the old sound short cuts on the power menu?

Htc one m7, changing power button

Is there a way to give vol up button the rights to turn on the phone? or at least just wake it up, my power button isnt broken but it is kinda stuck in the bottom, so now it requires much more pressure to make it work :c
or another thing to be abble to wake up the phone without pressing power button
thanks!

you could use a custom kernel with double tap to wake or sweep to wake features but you'll still need to use the power button to power on the phone.

HTC One M7 Battery life test aggressive use
hi,
I just did a review on the HTC One M7 battery life, which i heard on youtube before purchasing the phone that it was not good, but found that it really holds up pretty well. Here's a video with the test details.
Is anyone else out there getting the same lifetime for the battery with this kind of use ?
thank you

Mi A2 power button suddenly not working and No Command

Hey guys. I own a Mi A2 since November without any issues. But this morning, suddenly the power button is not working. I thought something is wrong with the switch, but when i double tap it, it takes me to camera app (short cut button) which explain the button works fine, but i cant turn off the LCD/lock the screen. Then I restart the phone by long pressing the power button and it resets, but then after Android One logo, a "No Command" pop up on the screen. As I'm confused, i long press the power button again, and it's restarting just fine. Is there something wrong? I am not modifying/installing/routing the phone at all. Well I'm just curious what happened as it's really worrying me. Thanks!
Same issue
I have the EXACT same problem, plus my volume up button doesn't work, and sometimes the system randomly increases the volume. I was wondering if you have found a solution to this problem and would like to share it with me, I hope you'll see this and respond to it.
Thank you very much in advance.

Your problem is different ..if volume is increasing by itself it means your button is physically getting stuck ..
Open your device and check if something is putting pressure on the buttons or making them getting stuck
