[Problem] Optimus Black Touch Keys Not working - LG Optimus Black

Hi everyone! I am new around here , as a user, but i visit this forum every day.
Just compliments for you guys!
Your tutorials helped me many times, your ROMs got my phone alive and lot of other things.
But now, it happened to appear a problem that seems to be impossible to fix.
As the title sais, the problem is that the soft keys aren't working anymore.
I flashed Gingerbread and ICS official firmwares with Smart FlashTool but they didn't solved the problem.
I ran a keytest in CWM and they work fine.
in the log appears that each key command equals to 0 while the touchscreen touches equals to some strange numbers like 63738291.
the commands also work on gingerbread when the phone is plugged in,and even then the whole touchscreen goes crazy.
So, i don't think is a hardware problem.
I found sort of a solution of editing a database in an internal folder /data/data/com.android.providers.settings/databases/settings.db , but i don't know how to edit it.
Can someone help me?
Does anywone have the fix of this?
Right know i am using SlimBean with Navigation bar, but is frustrating that i can't use the main keys.
Is about Menu, Home, Back and Search keys.
Excuse me for my bad english, i from RO.
Also, if i am posting this in the wrong section.
Thank you!

having the same problem sometimes ... usually outdoors when the temp is under 20C ... indoors are working fine BUT outdoors (example: in a car ) when I plug in the charger are the soft key working fine, til I remove the charger.

I think my problem is about remapping. They work in CWM key test and show 0! Can someone help meee?!?!

Backlight is gone

hello there, i have a diamond with a custom wm 6.5 rom
never had problems with it..
but when i woke up this morning i noticed that my phone didnt have any backlight on it..
i've searched through the settings and it all should be ok, i even have a backlight application setting that i use to specify the power of the backlight and its set to maximum even plugged on the ac adaptor...
what could be the cause of this?
will putting a new rom fix this?
or is this a hardware error? im open to try and experiment with the phone
many thanks in advance
ok, i now have tried putting 2 new roms and the problem remains, so i might guess its a hardware problem..
is there anyone here who can guideline me to try and fix this backlight problem? i have a friend who works with that kind of stuff, wiring and etc, if i give him the instructions maybe he or i can fix this..
regards

Installed and tested 2 roms is 4 minutes?
Wow!
i've tested 2 new roms before the first post, had some connection problems to try and post the first message, as soon as i got through, i send the 2nd message with the info i forgot to post on the first message...
as i searched through the web, i see this is a really common problem on the diamond, with no apparent easy solution, the only guys i saw that had a solution, were the ones who send the phone back to htc center for warranty repair and exchange motherboard or something
is there a alternate easy way to fix this by now?
regards

Blackout while sliding

It's weird everytime I slide the keyboard the screen is like blackout for secs...
About my phone:
I bought a second hand X1 online. And I sent the phone for being refurbished by a ' refurbisher' shop online too. The keyboard, casing and digitizer is fixed with new box and new accessories.
i read after google about bad cable in X1 but my problem is temporary. can it be an initial sign of cable failure???
ADD:
Sometimes the screen become irresponsive at all. I have to reset the phone manually. Is it another intial sign of something?
i have the similar problem,but mine is worse
when i slide my keyboatd out my screen completely blacks out,and i need to slide back in,then wake up the phone.i still havent found a fix for that.
Oh the dreaded flex ribbon issue. There is a fix for that, you have to buy a new one and replace it. Unfortunately you will have to open up your device to replace it, which is easier than it sounds. Here is a link that details the issue and the possible fix for it.
http://forum.xda-developers.com/showthread.php?t=561151
I eventually upgraded because the flex ribbon goes out all the time. I've replaced mine 3 times already. Sucks because I really liked the keyboard on the X1. I still contemplate re-fixing it for the hell of it.

Oh yeah, here is another thread on issues with the X1.

The second post has youtube videos on how to open it up.
i think is flexible cable problem

[Q] Screen not longer touch

Hi, I have Xperia X1, and the touchscreen is not working. I use virtuamouse, and that helps me to use the ''phone'' (using that as an palmtop). How can I fix the screen without paying?
Please use the Q&A Forum for questions &

Moving to Q&A
Hi VaderSKN,
I also had a problem with the not working touchscreen last week. I also used the virtuamouse appication but it was hard to download this app without computer on the x1 with broken touchscreen
Try to disassemble the phone and remove the dirt between the display frame and the touchscreen.
Another way I read is to remove the battery over night. Maybe this will work for you.
Hope you bring your X1 back to work.

Display problem

Hi,
I was wondering if anyone has faced this problem before.
I was charging my phone and listening to some music simultaneously using an aux cable in my car. As soon as I removed the aux cable and the charger, the call display changed into some weird language or symbols(I could not understand any of it). The dialer page, call log page, favorites page and contacts page were not readable. It was some sort of symbolic language which was very hard to understand. I am using the matrix live wallpaper. The symbols were something like those that fall in the wallpaper. Everything else on the phone was fine including messaging, internet, playstore etc. I already posted another problem which I was facing because of the charger. I'm not sure whether I should change the car charger or not use one at all. It's a 1 A capdase charger. If it's not a charger problem, would it have anything to do with the aux cable? Or would be a problem of using both the aux cable and the charger together?

No vibration at random times

Hi
I've noticed an odd problem the last few days, my phone vibrator suddenly stops working. It'll work for a bit and then suddenly stop and then start again without any apparent pattern. I downloaded the Sony Diagnostics app and it fails the vibration test when this happens - the problem is system wide.. The only recent things that I have done with the phone is wash it briefly after using it with dirty hands and changed my sim to go from 3G to 4G. I don't have any other issues with the phone, a restart doesn't always solve the problem
Anyone come across this before?
Edit: fix title
Bump..., it just happened again now
same problem
I have the same issue, but if i turn the mobile in landscape then tap the mic end of the phone whilst running vibrate diagnostic the vibrate comes back intermitently!
Seems like this is a common problem across the Xperia line of devices, there's quite a few threads about other devices with similar problems. Usually giving my phone a shake brings the vibrator back to life for a short while. It's starting to seem like it doesn't work more often than it does
Mine just stopped working today ugh. Let me know if you found a fix for this. Hope it isn't hardware issue
It must be a hardware problem if giving a shake brings it back, it sounds like there's something lose inside although I don't know if that's just how the vibrator is designed to give it space to vibrate or something else. Sony have recommended I send it in for evaluation, gonna be a pain
Giving it a shake does not solve a thing...
Still, instead of sending it to Sony for repair, I got a replacement from Amazon who is shipping the replacement before I return the faulty item...

I sent mine to Sony under warranty and they've replaced some components. I've not managed to start using it in full again but the diagnostic app hasn't flagged up any problems yet
Same thing happens for me.. I googled it and read a post somewhere and someone said it only stops working when he is typing and shaking the device provides a temporary fix...
Shaking it did work for me as well only for a couple of Mins then it stopped again.. I turned off vibration feedback on my keyboard and the issue has not returned.. So for me it seems to be a matter of rapid use

It happend for me 1 month ago after i listen music during the shower
Vibrate stop and not work until you shake phone.
Anyone could fix it?
I email to usa support and repair phone by their steps last night. But nothing changed.
Unfortaunatly my phone doesn't have warranty and even we don't have official sony office in Iran.
Important
any fix guys ??
i have the same problem !
Same thing here, keyboard kills it and shaking (massive shake from up and downwards) brings it back..
All is temporary of course..
Can some one please post updated information? Did you find software fix? Hardware fix helped?
Please note.

Also guys, lets find some common stuff maybe theres something we all did that caused it
For example i have:
1. Rooted
2. Recovery installed
3. Xposed installed
4. Modded dual speakers for calls
Mention if you've got any of these or other things that might be related..

I also have this issue. This issue has been occurring since the first Lollipop update. Never had a problem with KitKat.
My phone is stock with a full wipe install of 5.1.1. However, I did have all my apps reinstalled before the issue occurred. I never tested if this issue occurs with no apps installed as this is my only phone.

Mine stopped working also.. No shake or bump fixes this, not even temporary. This is so annoying, i never appreciated this feature so much, guess i took it for granted, but now that it's gone.. i'm constantly missing calls and texts..
Good part is now that it started falling apart for no reason, I might as well unlock it's BL and start messing with it
I have been having the same issue with my xperia z3. Vibration stops working when typing or spamming home and back button at random times . I can't see any pattern to it nor any reasonable explanaition to why this is happening. I have never let water come near my phone, nor have I ever rooted it. A tap on the bottom right corner always fixes the issue until the next time it happens. Has anyone found a permanent fix or what the root of the problem is? I feel reluctant to send my phone for repair as it would definitely take more than two weeks. I am also worried that once they open it for a repair it will never be waterproof again. As I can see, a large number of people are affected. Any solution?
Same problem here with Xperia Z5 Compact, but I also have another problem, because vibration does not work at all on vibration mode.
The phone is new, I have latest android update from Sony.
It is working when the sound is on, I have checked settings, and it says vibration is on.
Hi there, I have same issue with my Brand new Sony xperia E4g, i've bought it only for 1 week. I think this was hardware problem, when shaking my phone, it work, then when i turn it to some another positions, it doesnt work, or sound weird then doesnt work. Over all, it will work if i give a shake, then doesnt work in some specifical positions. Anyone have idea? should I take it to warranty service? Thanks
Same problem...
When vibration stop to work, you had to shake your device. So, the vibration will work again...
It's an hardware issue: I tried to flash another rom. I tried to root/unroot: it doesn't matter.
I sent my Z3C in warranty, but they didn't solve anything
I just had this problem a 2 weeks ago and today while writing message. 2 weeks ago, it just stopped working - so i rebooted device and it started working again. Today, it stopped working, so i just tapped back of phone, and it was working again. After a while it stopped working again, so i rebooted it and it's working fine for now but i saw a long time ago that sometimes that vibrations are randomly losing, and sometimes, that vibrations just feels and sound "weird". Specially when then phone is turned with screen upside down (that situaton happened to me every time when was laying in bed, on side or on back). I can't send it to support, i dont have any other phone that i can use as my backup phone... Ofc phone is rooted, xposed too, MM installed, and it had meet succesfully without any problem with normal water. Im washing it sometimes under stream of tap water, checking before that every side its closed properly...
