Problem with waking up - LG Optimus 4X HD

I'm on V20A, official, rooted. Sometimes I have to press power button 2-3 times for waking up the phone (sometimes not). Same for turn off screen. It's common problem? Maybe I'm pressing power button to gently, but I have not noticed this before V20A. Very annoying.
P.S - I don't have time right now to backup, do factory reset or flash CM or something, so I'm just asking.

Happens on every stock device (as far as i know). The question is if the devs are going to fix it in a custom kernel. But until then it seems like an annoying small bug.
The only solution i know is to wait and press the power button again.

I noticed you have to push button longer and everything works in the first time almost every time. But I have a bunch of other devices and I used to push power button very fast, so this bug really annoying.

Power on then off immidiately

I can bring phone from standby by pressing the power button as normal. However, the first time it will come on shortly then back to standby. I thought it is the lenght of time that button is pressed but as second time it always works. Could this be the ROM issue?

You should have really posted in the ROM thread, also done some searching in there.
It is an issue with the ROM but you can get past it by holding in the power button on wake rather than just pressing.

Power Button- slow?

i noticed recently that if i press the power button, it sometimes takes a really long time to turn the screen on. i know the hardware works because the backlight in the soft buttons turns on immediately, but the screen remains black for up to 10 seconds. this happens rarely. however, im fairly sure it isnt a software problem because ive wiped completely and installed a fresh rom and the problem seems to persist. perhaps i just recently noticed, and the problem was always there? does anyone else have this problem?
three threads above yours.

could be a hardware issue.
Mine does this every few days.. I am still on the stock 2.1 rom.
Mine also does this, I only noticed it after flashing Cyanogenmod 5.0.6. so I thought it might have been a bug. I also assumed it was a bug because the phone seems to act strangely when you are touching the screen and try to hit the power button.
Hopefully this isn't a hardware issue, I've had the phone since release.
Is anyone else experiencing similar issues?
It happens to me as well, but very infrequently. Maybe every few days... so it doesn't bother me enough to worry about it.
I'm on stock ROM btw.
I am leaning towards thinking this may be software related. A few minutes ago I was at the lock screen and tried about 50 times (yes I waited long enough after each press) and simply could not get the screen to turn off. I then tried long pressing the power button and, sure enough, each time it would bring up the shutdown menu (yes, over the lock screen). Must be a bug right?
Hmm, my problem's slightly different. Around half of the time, I have to press the power button twice to turn the screen on. Sometimes, pressing it the first time doesn't turn the screen on, had to press the power button firmly again.
This started only recently. On stock n1 and bought it during feb.
that means that your power button is dying, like many others' (including mine)
this is the first time, it takes 2 clicks to work....than it will increase.
Expect a repair soon...
Well i am having the issue other way around. i am not been able to put my phone in stand by mode by clicking on it and it is do a hard press then i get options to shut off the phone
any suggestions what might be causing it ?
I'm happy I haven't received this problem yet

I am having the same issue and i wonder if you were able to find the cause for it. I have the same rom as you do on your phone

I have a similar problem. When I unplug the N1 from the charger, the screen comes on showing the lock screen, and I can't get it to turn off. If I unlock the phone, however, then the power button works normally. I don't think it was doing this until recently (I bought it in January the first day it was offered and am running the stock update1 ROM).
So here is my theory if the power button is a problem then it needs to act up both ways and not only one way. right now i can put the phone in sleep mode but i can wake it up. i will post the issues on the development forum and might be able to find an asnswer to it
So seems like the issues is because of Cyanogenmod 5.0.6 because since i have flashed another rom it is working just fine. i will be doing some more testing before i can be certain
Another problem I am experiencing is when I long press the power button, it pulls up the phone options menu but also turns off the screen. It's extremely frustrating as it does this quite frequently; right after I power on the screen again and unlock the device it works properly every time - so much so that I am convinced this is a software issue.
I am now running froyo, rooted with Cyan's minor root patch. I can also say for sure I experienced the same problem on CM 5.0.6, but it definitely occurred less frequently.
Am I alone here?

I just started having this problem after upgrading to 2.2.
I have this every so often. But sometimes wonder if it is flyscreen doing it
You guys should all just be running the app no lock to take the power autumn out of the equation.
Ahhhhh! I just need trackball wakeup!
I have a similar issue where my screen will turn on but will be unresponsive. When i turn it on and off, the backlight jut comes and goes. If it times out it won't turn back on for a bit(the backlight will come on still).
I just wiped my phone, hoping that'll fix it since it only started happening on a regular basis since I updated to Froyo

[Q] Home button reboots device

Hello,
My X8 has started to behave very strangely recently. I had Naa Jb kernel with 4.1.2 on my phone. After some time, it wouldn't respond when I pressed the power button. Since then, that button doesn't work at all. This is the lesser evil. My other problem is that when I use Naa kernel-based roms (both on naa14 and najb), when i press the home button, it reboots. On the stock rom/kernel, this problem doesn't exist. I have done nothing special to the phone recently, and I accepted that the power button doesn't work, but the strange behavior of the home button freaks me. Now what should I try? Should I try alfs kernel?
Thanks in advance!

If the Power Button does not work and the Home Button let's the Device Reboot, it seems to me, that your Power Button is constantly pressed.
A little Information:
If you press both the Power and the Home Button, your X8 is forced to Hard Reset, which means it Shuts down immediately and then it starts again.
Does it Shuts down instantly?
If you can answer this question with yes, then you should try to pick out the Power Button with a Needle or something like that.

Well, (first, thanks for your reply), the following has happened:
Although I didn't seem to get stuck in, picking it out helped me a lot. Now, the phone does not reboot, the home button works fine, but the power button stills shows no signs of accessibility. The hard reset method results in nothing, only the home button does the action it has to, but the power button still remains irresponsible. It makes me think that the physical connection is lost somewhere inside the device.
Thanks for your answer, if you can advise anything else helpful, I appreciate that!

If you say it only happens on naa then you should try alfs kernel. Alfs v09c on my x8 is very good without any battery drain and also use minicm7 rom . If minicm doesnt work well for you, then try gingerdx.

But if the Hard reset worked before, why doesn't it work now?
The Power Button seemed to work, because it did the Hard Reset.
This problem just appeared to me too... exactly the same! Is there any solution?
I changed the POWER button with the CAMERA button, i can now close the screen but i cant open it -.- . And the home button still gives me a reboot. Any advice? How can i desable it?

Can you change the bootloader? - Hard reset no longer working, Any insight?

So I have been trying to overcome the issue of power + vol up (held for 10, 15 seconds\ and more) not working on my device. No matter how long I hold the two it just won't reset the device.
At first I figured it could be kernel as that is the lowest code that I've knowingly changed.
Changing to back to stock kernel did not fix it.
I thought it could be any sort of thing so I redownloaded the NL 434 firmware and then also universal generic 434 firmware and flashed back to completely stock with flash tool, doing all wipes and excluding nothing.
Neither of those firmwares fixed the issue, the hard reset function still won't work on my device.
Additional info:
Both buttons function fine individually and can see no obvious reason to suspect it's a hardware fault (though see that it is feasible, just less likely).
I can confirm that it was working initially.
I have an unlocked boot loader.
The last time I can remember it functioning was prior to boot loader unlocking - the first thing I flashed after unlock was cm10.1 and I got stuck in sideload mode with no hard reset to get me out lol
Otherwise the device is fully functional. For the time being I am back on KA07 xperia revolution rom, with advanced stock kernel (cwm) from DooMLoRD.
If anyone has any suggestions or insight it would be greatly appreciated if you'd drop a comment :good:
EDIT:
I've restored back to 350 with EMMA, but to no avail . It did however tell me that my boot version is : 1264-2309 S1_Boot_Lagan_1.0_2
Is there anyway to change the bootloader :S
After getting home I tried re-locking the bootloader which didn't work.
really starting to wonder if I should be taking it back in as hardware fault.. wonder how that will go since I unlocked the BL
If anyone would be so kind as to do a quick test for me, would you please be able to go into service mode (open dialer type *#*#7378423#*#*) then go into service tests and select the buttons and switches one (I think that's what it's called )
When you hold down the volume up or down button, is it registering as 1 press, or several, continuous presses?
Cheers

Not entirely sure what you are asking, keyboard and switch, volume up only shows as volume up and volume down as just volume down, regardless if you hold it down or press it over and over again, or if you just press it once. Not sure if I am an idiot, but I couldn't work out how to test the keyboard from there.Although one interesting part is that is states it is not a test for the softkeys, but tests them fine

Yeah that was the menu I meant.. couldn't remember lol. Ok so when I would hold down volume up it plays a repetitive tone and the text on screen states "vol up", then "vol up vol up" for the longer I hold it (and the beep/sound keeps replaying... confusing sounding I know
When you hold the volume up botton down, does it just beep once and display vol up (exactly like if you were to press it once and release)?
Basically if I were to press it once, the phone would make a sound and the screen would display "vol up"
If I hold it down however it will register as a new press and the "vol up vol up" texts keeps refreshing as-though it was a new key press.
Also thank you very much for checking it out :victory:

Yep exactly as you say here.
Volume up once shows just volume up beeps once, twice shows volume up twice and beeps twice . Holding it down beeps over and over again and shows volume up twice.
Pressing volume down once from here (volume up volume up) shows volume up volume down, press volume down once more now shows volume down twice.
Hope this helps

Yeah it helps that I can probably assume that my buttons work fine.. I was thinking maybe they weren't registering as long pressed or something but apparently not this is really frustrating. Especially when an app freezes and I just have to sit there indefinitely till it comes back online or the battery goes flat
And I have no idea if it's something I did or something with the phone.
All I know for sure is that brand new it did work as I hard reset a couple times. Then I unlocked the bootloader and have no memory of it working since then... It makes no sense to me why completely returning to stock and relocking the bootloader has no effect though.

Yeah, I could imagine. You will have to find a cool fast battery draining game to help you along .
Not sure that it would be related to you unlocking the boot loader, otherwise I am sure quite a few would have mentioned that before now.
Do you even get the first vibrate confirmation? Have you tested the vibrate from the same service test menu?

That what I'm thinking - can I seriously be the only one having this problem. And why the hell does everything else work perfectly fine lol.
And no I don't get any sort of response (vibration or anything). Normally it just results in the volume turns up then the screen locks or display just times out but even after a minute of holding pwr + vol up nothing happens and the phone is simply in sleep mode. Otherwise vibration works fine.. currently I'm restoring the backup I made of the out of the box stock rom.. that's pretty much the absolute last thing I can think of that might do anything. Trouble is I don't remember if I made the backup before or after unlocking the bootloader.. can't remember if I flashed a custom kernel to get CWM or installed it otherwise...

I would recommend re unlocking the bootloader, the problem is a kernel level driver or hardware but it is definitely around that level.
Did you have any problems, or errors when you first unlocked the bootloader? Maybe Doomlord could give you some of his incredible knowledge on the subject

No the phone is 100% operational outside of the hard reset not working. It is just when I get stuck in a app that freezes or when CWM recovery tricks out and freezes I have to leave the phone for ages till either it a)unfreezes after an hour or so somehow, or b) the battery dies and it shuts off after a couple or more hours.
When your phone is out of action every second day simply cause you can't turn it off it gets pretty annoying haha. If it had a removeable battery I could easily live with it and just rip the batt out no dice.

Stranger still is that I've began to notice that in flash mode the LED briefly flick green once then turns off when entering flash mode. Flash mode is still active, it just appears as though the phone is off :/

(Q) Screen stops responding?

So across all roms including stock and cm based my touch screen will randomly stop working and i am forced to reboot the phone via the little pin hole method unless i am missing a hardware key reset combo? Anyway the screen turns on and everything looks like it works except the fact that none of my touches register at all? How do i fix this issue? Its not a big deal when i am at home with a pin or pencil but sometimes i am away from home and cant reset it...

Well, just hold down on/off button and power up button for few seconds. You will feel a vibration. It will restart
Hold it a bit more and it will switch off with three vibrations.
I guess you should get your phone checked. It seems to me hardware problem. it could be a bug too but chances are slim!
Secondly, try clearing dalvik and cache but I am afraid it wouldnt be of help!

Just go on stock rom n relock your bootloader. Sony might ask and make sure you say nothing about rooting, custom rom or anything. Just it's not working well should be the answer.
Secondly, try volume down +power for few seconds when phone is on. Even try volume up+down +power for few seconds.
Make sure you hold these buttons simultaneously.
