Optimus black soft keys random clicks - LG Optimus Black

My phone is now unusable, once you turn it on the soft keys will light up on their own, any idea how to fix? It will randomly click home button and will exit everything you're doing.
Could it be my screen digitizer? I'm running the ics leak.

i can't unlock it

Today I noticed that the power button does not work because when I can not unlock, but to remove and replace the battery automatically turns on what I'm thinking is that the power button got stuck
any idea?
Going to need alot more info. Where you running stock or custom rom?
Sent from my Captivate using XDA Premium App
im not running a rom, i stay in stock rom.
all started when I received a text message and read the message, when I wanted to block it and not work the power button. I have noticed that sometimes it works with a few strokes with my fingers but it shows me if I turn off the phone. I believe that the power button is stuck

sometimes with few little strokes xD
when I put the battery automatically turns on, but if I keep pressing the 3 buttons combo I can enter recovery mode, but don't works power button in this mode =/
I'd try an clean around the button and if that works
I am not sure thus will do anything but if you can't get your phone running at all you can try to Odin flash stock to see if maybe it clears the problem. If you cab get into recovery then the power button works for something

yes that's the problem, i cannot get to enter to download mode Because the phone will automatically turn on
Try this. Take battery and sim out. Plug USB in. Hold volume up and down. Put battery in.

Inzombie, what exactly did you do? I have been having the same problem for quite some time...I was able to get into download mode using a program I found on the internet, and I flashed back to stock but the power button is still messed up, it doesn't work at all. What exactly did you do
i know this is an old topic but I have the same problem. I got this phone from a friend and now I cant use the power button. I have taken it apart twice now trying to fix it with no luck. I know it isnt the rom. The button is "stuck" but it still clicks. I know it is stuck because it will never turn off. Once battery is in it turns on, and for 3 button recovery, I only need to hold the vol rocker.

[Q] Won't turn on

Hey guys
I have a mate whose SGS i9000T will no longer turn on, it is about 5 months old, battery is fine and just died while the screen was off, was not even being used. The last app used was browser. Can't get into Recovery or download modes and the backlight doesn't even register while the AC is plugged in.
Any suggestions would be great or is this a hardware fault? which too me it sounds like
Theirs two possible reasons for this bud....1, custom firmware incorrectly flashed. 2, hardware. I had the same problem and I had to send mine off to Samsung, if you blame the damage on Kies, say after the update it wouldn't turn on they will fix it for free.

Cheers for the reply,
The only things applied were a lag fix that was weeks ago though so i doubt that is the problem, sounds like hardware problem then

No custom kernel or anything? And it just died? Does he tend to drop his phone a lot?

In that case I'd put it down to hardware bud! Are you in the UK? as we have dozens of Samsung service centres, just blame it on Kies if I were you, say after the update it wouldn't turn back on, and they'll fix it for nothing bud

Can`t turn my Xeperia Z on

Hi,
i got my Xperia Z yesterday and already have a problem. Yesterday in the evening i listened to some audible content. I didn´t turn off the app, because it goes in sleep mode after finishing the downloaded part. I had stamina mode active. Today my phone doesn´t react. It is off the screen is dark. I can push the powerbutton how i want, the phone doesn´t react. I tried to recharge it, because i thought the battery was completly empty, but i don´t even have the led active which is normally active when you plug in your phone.
Does anybody have had the same issues? And can give me a hint what to do? Otherwise i will have to change the device tomorrow. It´s my first sony, so perhaps there is a trick with it i don´t know.
Take it back.

Hardware reset combination...similar to a battery pull for devices with user changeable batteries.

Can some1 check temps?
Might be a safe mode of sorts due to overheating?
Sounds like this is a common issue on the forums.
i don´t think its because of overheating. Today it was two times in sleepmode for a bit longer, and after both i had to restart it with the method mentioned above. I think it is a software failure. Maybe something with the staminamode. I will switch the staminamode off and wait if it happens again.

I imagine a small firmware update will fix this. Be sure to report it to Sony every single time it happens.
Yes, i will do that. Bsides this bug, i´m very satisfied with the experia z, even with the battery life.

You don't have choice if the phone freezes
Sent from my GT-N7000 using Tapatalk 2
Ever since they introduced non-removable batteries with XS ( and I still have a bone to pick with Sony regarding that choice ), they introduced a hardwired phone reset/shut down combination that is accessed via volume up+power button, that apparently by the sound of this thread, still functions the same as it did with S.
I've had my Xperia S freeze in middle of something ( can't remember what ) after it went to standby mode, and the only way to fix it is either to wait for your battery to die, or to manually reset the phone via volume up+power button combo.
It's safe to perform as much as you'd like, it just resets the phone or shuts it down, depending on how long you keep it pressed. It saved my Xperia S from water damage on one occassion, although I guess I won't have that problem with Z.
The same thing happens with my nexus 4.. Its somewhat related to hardware I guess. Cos xperia z and nexus 4 are very simpilar in case of hardware. around 10% people are facing such problems on nexus 4. Its a hardware problem I guess..

Should home and back be illuminated ?

My home and my back arent illuminated I'm sure they were when I got the phone
Reviews show them lit .. before I ring 3 for a replacement I want to check
Thanks

cover the 2 sensors on the top left with a piece of folded paper or something, do they light up?
Ah yes .. I'm sat under a bright light doooh thank you
Thought my home and back was faulty . It sometimes is less responsive than other times (double tap to get multi apps ) but I'm presuming that's a software glitch
Sent from my HTC One using xda premium
Others are reporting issues with the buttons sometimes not responding, not sure if it's a software glitch, or just a small footprint for the buttons, ie you have to press right on the button and not in the general area if you know what i mean.
Cool I'll relax then and stop worrying my phone is faulty. Big thanks
Sent from my HTC One using xda premium
I would monitor how you go with pressing the buttons, it may be a glitch, but i know when i'm using mine, i am often off the button when i press it, being used to the One X for the last year, the buttons are further to the edge, so automatically i have been pressing further out than the actual buttons are.
I always turn mine off. Just saying lol

The capacitive area is in fact VERY small. Just barely bigger than the Home and Back icons themselves. Precision touch is required and is why I suspect some think its not responsive

I use an app called keyboard backlights from play. Works great but recently in occasions they come on anyway. They are off 80% of the time though. Can only do if your rooted btw

Try this, http://forum.xda-developers.com/showpost.php?p=39498430&postcount=7
Seems that the One has very small area of touch for buttons, so probably not software problem.
Turn on vibrate and you will realise how small of an area we have .. seems the way it's been designed and not a bug . Vibrate assists because you know when your missing now don't have the issue

Simulate battery pull problem

Has anyone else had trouble doing simulated battery pull? Ive done it before but when I just went to try it, it gets to 1 sec and doesnt reboot. Even held 30 secs longer and nothing. Anyone have any idea why that is? Will it only allow simulated battery pull when phone freezes?

I had to have the sensor in front of my laptop when I was doing stuff in the dark.
Sent from my HTC One using xda premium
Weird how the proximity sensor can effect the powering on/off of a device. Never had that probem before. Then again Ive only owned one other phone without a removable battery. Had the htc 4g lte for a short time before getting this htc one. Is this just a software "glitch" that could be fixed with an software update or something in the htc one hardware?
Sent from my HTCONE using xda app-developers app
Sad part is, wasnt long ago I read somewhere on xda how someone was told to do the bright light when they couldnt get their phone to power on and it worked. Never dawned on me to try that to restart it..well simulate battery pull anyways. Never seems to restart (maybe Im just impatient lol) without pressing power to get it to boot back up.
Sent from my HTCONE using xda app-developers app
Never own a phone with build n battery so this is new to me. But cool tip I will remember this.
You just aim the light sensor but the speak to a bright light and press n hold power?

Yep if you want to do a simulated battery pull or have trouble doing it or getting your phone to power on. Just hold phone (sensor part anyways) under bright light and it should work
