Problem with lock key - LG Optimus Black

hi
recently , my friends and i having a problem with our Obs
we should push the lock button so hard for unlocking the screen! it wasnt like this before! what is the problem!?
we use 2.3.4 official

It's possible the switch underneath the button has been slightly dislodged. Try reflashing firmware. If problem persist, have it checked by lg.

is not rom related... it happens to me too since a month ago or something... is the button itself like is not pressing correctly or something

[Q] Lagging or weird hehavior found on my buttons

I have been having this weird problem for over a month now.
Virtual Button gets stuck as if im touching it rapidly. it happens randomly too. for example, after a reboot i was using xda app. After hitting "back" button, its button backlight goes off and doesnt respond. Everything else still works but the button gets stuck like that for 20second.
Sometimes when im watching a movie without hording it, quick option pops up as if i have pressed the button next to home button.
anyone else with this issue???
I have 2.1 stock rom uptodate with kies, ryan lag fix, and realook screen protector on it.

This just started happening to me (literally 15 seconds ago) and I want to find out what's going on.
+1
same thing happens to me. But after pressing the central button, the buttons reappear. strange weird
I do not install any lagfix or change the rom, I have my Samsung Galaxy S as a wine factory
I just started to have exactly the same issue with my Vibrant.
Any follow up on this?
Well, one thing i wanna ask you guys is that how many apps do you have installed on your system? Im actually having less of this symptom these days as i have uninstalled dozens of software. Not sure if that was the issue tho.

I deleted few apps which I installed in last few days and so far so good....but its just few minutes of use yet!
Specifically deleted "Noled".
Still getting lag with BACK button. Though it happens once or twice a day....very weird!
I have been using Samsung Vibrant for 3 months now and this problem just started two days back.
I'm having problems with buttons going off by themselves now. Browsing the internet or writing a message, the menu pops up by itself; Its annoying and its starting to get worse. I'm starting to wonder if I should trade in my phone; this is my third phone.
// galaxy s
I too have this exact same issue with my i9000m. Stock rooted rom with voodoo lagfix. Uninstalled everything, factory reset, clear cache, unroot - nothing fixes it. I have a replacement phone on backorder that will be replaced no questions asked thankfully.
Sounds like it's a somewhat common problem.
now this is getting irritating! seems like an issue with only Bell version I9000M. Couldn't find this problem any where else on web.
did a hard reset and before loading any apps..... played around with phone and found the same lag with back button!
After looking at your replies, it seems like these two factors are causing this strange button lag:
+Bell Mobility
+2.1 Éclair
Can we confirm please? Are you all using Bell & 2.1 with the issue?
Hopely Froyo can fix this issue. My phone was alright for couple of weeks but it came back worse than ever!
I’m starting to hate Samsung more than ever for the lag of updates & lies.
it might be only with some phones
i'm on i9000m as well, 2.1 stock, but i do not have the button problem you guys are describing.

AllGamer, I think you're the lucky one when it comes to your Galaxy. I'm curious if this issue happens to phones running custom roms or the official froyo release.
On stock firmware i9000m and OCLF with root. Im getting a huge lag (10-15 seconds) whenever I hit my home button. Using launcher pro but the problem only popped up yesterday.
Checked watchdog and it only shows 4mb free BUT task manager shows 65mb free. Any thoughts?

You're not the only ones with the issue. Look at this guy using a Bell SGS on youtube (apologies if this is one of you guys )
http://www.youtube.com/watch?v=JBe0txXobwY
Also, its not just the Bell SGS, my AT&T Captivate does it on the Menu key and its very very annoying. Theres a similar thread in the captivate forum and no doubt, on in every SGS forum as they all use the same touch panel.
If its very common, which seems to be the case, could it be related to dust ingress into the touch panel?
Disabled Quickdesk (glcery handy app), left the office early, and now everything works great. Not sure which one worked....
I was getting a black screen for 5-10 seconds every time i pressed the home button. Anyone else with quickdesk issues? Suggestions?

I factory reset my phone and then un-rooted it just for the sake of testing out some ideas. It didn't help at all and the problem persisted for awhile until I found something interesting;
If you are having the buttons 'stick' or malfunction, go to recovery mode via 3-button. Once you are in there, start pressing your soft keys (I did this for 10 minutes straight when my buttons were sticking).
Tell me how your buttons respond, do they stick or not? We could determine if it's software or hardware.

I thought the buttons didnt respond in recover mode...
They light up and respond to touches; if you press the menu key it actually removes and restores the recovery screen.

Back button stops responding issue

Hi guys I have been facing a problem ever since I got the device and do not know whether the issue is only with my device. The issue is that with all the roms the capacitive back button stops responding after a while and I have to turn off the screen and back on to get it to work for a while and again repeat the procedure. Is there a fix for this which I may have missed. I an using buttons saviour for now. Thanks.

My device always got that issue when I used my device heavily usage,especially when my device get hot/warm
Just screen off then on to reenable back button normally
I think main point in hardware device

same problem.... just hit home button and the back button "back" alive for me
switch between launchers
well i also have that problem.i also know others with this problem.in my case restarting the launcher helps.ofcourse if u r getting both the home and back button not responding at the same time then its not possible.i get both of them not responding at the same time very very rare.at that time all i do is turn of the screen and wait a few minutes.thats all,every thing is normal again.oh one more thing i think its a good idea to keep more than one launcher installed and not making any of the default.it helps switch between them easier.switching between launcher always helps in these not respondig issues.
same problem
camera not connecting

now i am also facing camera not connecting issue at times.
I do have that camera issue you have sir, at rare times. Is it hardware failure in the works?
don't know mate. i have this time an again on most roms, previously i thought it was due to bad sdcard. But i am facing this from past 10 days or so. The phone killed one of my 16 Gb class 6 sd cards.

[Q] During touch input "P" key not working

Hello,
I'm having a serious issue with my Incredible S. I bought it 8 months ago. Until last week everything was just fine. I'm using "RCMix3D Runny v4.0" ROM for last couple of months with no problem. Suddenly whenever I wanted to type the "P" key it doesn't work in touch input. All other key's are working fine. But specifically "p" not working. I tried "GO keyboard" as well. Didn't work. But the "p" key works if hold the phone horizontally. So does that mean that specific region of my phone touch screen damaged? But i can scroll up and down over that region. During game play it also works. Any idea folks? Anyone else having this trouble?
Regards.
Try rebooting your device

Try rebooting the phone, or try restoring a nandroid or try re flashing the ROM (clean install).
I did hard reboot couple of times. But still no luck.
Download "touch test" from the market to check your digitization.

I also had a problem.. my ph crashed (force close) a lot of times. it came out of nowhere.
so, I cleaned everthing on my ph ( factory reset /wipe data,partition/format )and flash new Rom.. . and got it fixed.
So, u should try that. ( at least factory reset thing.. )
As a simple test if you have a Bluetooth keyboard can you pair it with the phone and see if you have the same problem? This will tell you whether it is the touch that is causing the crash or the key 'p'. HTH.

Well, if I type in by holding the phone horizontally.. i can type the letter "p" just fine because the keyboard is in horizontal mode that time... it only doesn't work if i wanna type in holding the phone vertically (normal way)..
I bad that problem with nik's rom,with different keys,but rebooting solved it

I have a similar problem, some keys dont respond when I try to type something, it happened after a phone restore.
I heard about this problem very often, is this an hardware fault or can be fixed in some way?
Partial Screen Death
From what i see, it could be a case of partial screen fault, where the screen is not able to sense certain part of the screen as it is faulty. Download a touch screen test app like https://play.google.com/store/apps/details?id=com.the511plus.MultiTouchTester&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS50aGU1MTFwbHVzLk11bHRpVG91Y2hUZXN0ZXIiXQ... Go through from top to bottom, and at the faulty part it would "jump". If so, you need a repair.

You can try to disassemble the phone and then clean the button from inside... maybe that helps
This is basicly related to network.It happens only while using 2G not on 3G.so put your phone to 3G mode only.
Otherwise disabling home button also solves this problem.
Try searching how to disable home button on xda.

Lockscreen comes up every time I type

Hey guys !
I have a very strange and akward bug, which I can't find to solve. Every time I am using the android keyboard, for example to write a message or enter something in a fild, like google search, the screen just goes black. If I press the unlock phone button, the screen just unlocks, and I am back where I was.
BUT I cant write or search anything anymore ! Again : The keyboard comes up, nothing happens. If i press something on it, there comes and instant lockscreen and I need to unlock.
Does anyone have ever experienced that ? I am using the new v30a for about 1 month now, but it started 1 week ago. Today I updated to Django Manouche firmware, but sadly it did not solve the bug.
Help is greatly appreciated ! What could cause this suddenly ?
Thanks in advance
greets from germany
have you tried installing another keyboard?
Did you do a full wipe/factory reset before install DjangoManouche?
