Touchscreen issue - G2 Q&A, Help & Troubleshooting

So all of a sudden tonight my knock on feature stopped working. Then I noticed that I have a dead spot on my screen as you can tell from the photo attachment. I have no warranty so sending it in to LG isn't an option. I've did some reading and can't seem to find if this is a software or hardware issue? Can anyone shed some light here? It's a D803 variant. Should I replace the digitizer or not? I need a working phone asap as I'm driving across the country next week.
Thanks

Had this problem as well along with many others. I do believe it is a hardware issue. As far as your method of repair, I'm not sure. I got mine replaced under warranty.

I appreciate your feedback. Went to my local repair shop today and they are gonna replace my LCD and digitizer for me on Monday. $100 charge to do it. I'm fine with that I need a working phone especially since I'm about to drive across the country. Here's to hoping.

DZ: capacitive buttons unresponsive

litterally out of the blue about 2 days ago, the 4 capacitive buttons on the front simply do not respond to touch...
and EVERYTHING else is working fine, keyboard, display, trackpad, everything else is working w/o a problem...
the lights behind the buttons come on, but no response when pressed...
its currently running Unity 1.27 (since released)
ive tried the patch via CWM to remap the keys to no avail... i am going to try and get into titanium to run a backup of apps, then wipe and flash version 1.31 of unity hoping its a software issue...
the closest thing i found to my issue (DZ related) was an issue with the light sensor causing the backlght to act up, but that isnt whats going on here, so as of now im at a total loss...
any help or direction would be greatly appreciated...
Ok, I wiped, flashed and installed 1.31 and same thing... Crap it has to be HW related then...
Ideas?

If you are sure its hardware related, then try to unroot your phone and see if you can get a replacement from your carrier.

You need to buy them and replace them. They come as a set with microphone and vibrator attached. Very cheap on ebay. Middle plate has to be separated from glass to get to them.

only reason im leaning towards HW is because i already reflashed, and wiped the phone, and they still dont respond...
only problem is,im in FL-USA, and this came from canada... lol
buttons can be bought on ebay huh?
EDIT: would this be what im looking for?
http://www.ebay.com/itm/BUTTON-TRAC...232?pt=LH_DefaultDomain_0&hash=item3cb6a583b8
EDIT: wouldnt i be lookking at getting a digitizer? but if that were bad wouldnt i have more areas besides jus the buttons none responsive?
Can anyone help clarify the part I should be looking for?

Thank you-

Warranty with US LG

Hello.
I'm having issues with my knock on not working. After researching some on the forum, I realized it was because I have a dead spot near the top of my screen. Today, my phone was doing some phantom touches.
Immediately, I initiated an RMA. I read that LG repair has a really negative review. Has anyone else sent in their phones for warranty repair?
Also: phone has never been dropped or scraped, and is in perfect condition otherwise.
Sent from my Nexus 4, while driving in my Evo9.
I'm pretty surprised to know that no one has done an RMA with LG.

If anyone cares, I've sent in my phone, and it has been received by LG in Fort Worth.

Let me know how it goes.
Today is the fifth day since they have received my phone. I called to get an update, and was told that the technician is still working on it, but has not provided any updates. I was advised that they have a five to seven business day turnaround. I think they may be missing that turnaround time at this point.
Will update when they provide any info. At this point, they are still unsure whether warranty will cover my screen issues (dead spot, phantom touches, knock on is dead). Stock phone, nothing modified.

LG tracking shows that unit is being sent back to me.
I'm not quite sure if the phone is going to be in working order yet.
Wish me luck, because I have read a lot of reviews saying that the phones were never actually repaired m

Let us know whether they fixed it or not.
Finally received my phone today, on a Saturday with FedEx Home Delivery service.
Took the phone out of the box it came out, and immediately noticed additional IMEI stickers on the back of the device. The device came very dirty on the back, with stickers around the case. I thought they had sent me a refurb, especially when the scratches that I had on the main screen were not there.
I matched the IMEI with the one that came with the original box, and it seems to match.
They replaced the proximity sensor and 'updated software'. I still don't have knock code, however.
Customer service has been horrible, especially since they have absolutely no contact with the service people. CS knew absolutely nothing about the repairs.
Edit: Functions of the phone have returned to normal.
I developed the same issues with mine a couple days ago. Always in a case, never dropped. Dead spots near the top, no knock on. Gonna try to get it replaced by ATT first, otherwise will have to do rma through LG.
Basically, that whole bar is a dead spot.

There is another thread about this issue, which basically said it's heat that caused the sensor to break.

no double tap on / screen replacement /proximity

Hopefully someone can help me out. This is verizon vs980. I needed to replace my screen bc I got a dead zone in the digitizer. In my experiences with screen replacement, replacing just the lcd/ digitizer assembly never goes well, aftermarket double Side tape never holds it to the mid frame like factory. So I opted for a digitizer/lcd/mid frame assembly. Simply swap the guts. Everything went well. After about a week the digitizer began lifting from the mid frame (as though it weren't factory assembled) . Little mad about that bc it's the whole reason I opted for that type of assembly. So I decided to return it. This time,I figured if they're gonna lift like that from the "factory" I might as well save the twenty five bucks and just buy an lcd/digitizer this time and stick it to the mid frame myself. I did. Once I was totally done, everything seemed to be just fine. Then I realized the knock on does not Work, and my proximity sensor was acting up. Didn't worry about the proximity sensor since I'm taking it back a part anyway to send this assembly back bc knock on isn't working... So I sent it back. Got a new one, same issue ! No knock on and proximity sensor is acting up. So , suspecting proximity sensor as culprit I unplugged it. Still no knock on. So I then pulled the proximity from the housing and Used a proximity tester app to test it. When its out of the mid frame, dangling, it works fine (still no knock on) but when I put it back into the midframe housing the proximity sensor registers something in front of it ( no its not glue or tape, digitizer is unattached permanently at this point) confused I looked at pictures I took from that very first assembly that I took before returning. I found there is a black housing trim that I accidentally left in the housing I sent back ! It pops into the midframe, then the sensor pops into that.. I suspect this is why my proximity sensor goes haywire when it's in the assembly, but why is my knock on not working?! That black piece I left in housing ? Bad sensor all together? Coincidentally got two bad digitizers??? Rom? (Tried to different same result) stumped. So to sum it up right now, I have no knock on, and the proximity sensor constantly registers something when it's placed into the housing, but works fine outside the housing.
Did you update touch firmware?
Dial 3845#*8xx# / settings/ update touch firmware
8xx or 9xx according to your model , example 8xx/9xx becomes 802 on g2 d802

No I didn't, I don't have my sim card in to access the dialer. Suppose I could try that, but it worked just fine with the lcd/digitizer/frame assembly. Is this something you're supposed to do after a screen replace?

Red spots on phone

OK I've owned this phone for a year and suddenly red burn in circles are appearing on my screen. Anybody else have this issue and if not any advice as to how I can remove them? Or is it a service issue that's going to cost me a new screen?. Thanks

If you haven't rooted it, then send it in for warranty repair. If you have rooted it, you'll need to either live with it or replace the screen
It's a known issue. They show up in either red, blue, yellow, or white. Either send it in for warranty or replace the screen.
rooted since day #1

IIrc hardware defects are still covered under the warranty even with bootloader unlock. But I also have one of these dots. Towards the bottom, it's blue. Had it since opening the phone. Was going to send it in for reapir, but I couldn't figure out how to return the phone to stock.

LG G6 Vibration stopped.

I seemed to have this issue with an old V10 but I thought maybe after 2 years the motor just got old. This phone is still new and I have lost all vibration function. Has this happened to anyone else yet or does anyone know if there is something I can do to confirm a defect/fix?

I'm looking for that app and only finding things for human health...do you know the company name?
Are your sure it's not an setting or something software related? If a factory reset does not resolve then you likely have an hardware problem. I had a hardware issue on my G5 like that. Motor didn't work for weeks, then one day I dropped it worked fine ever since.

Lucky you. I wish mine breaks I hate the vibrator in Android phones. They all feel so cheap. I want it gone when unlocking the phone too but I can't. It makes the phone feel cheaper than it looks with its poor vibrator feel (and sound).
Happened to me last night, LG G600S

Yes. Or at least I believe so as when battery saver engages the finger print sensor also stops providing vibration feedback.

launch lg g6 (LG-H871 rev 1.0) - opening weekend. Vibrate function completely died yesterday.
Using vibrate app to test - no results on manual press. shaking the phone yielded no results. Gonna get a replacement.
Glad to know Im not the only one getting this issue
Did you manage to find a solution? Mine just started doing the same. Vibration stopped, checked with vibration test apps, booted in safe mode, factory reset and nothing. I'd rather not send the phone for repair and warranty is out of the question.
Damn I'm not happy to see this thread. Mine seemed to have stopped today. Not sure why or how. I'm gonna have to do some digging and see what's going on
Mine just started the same thing. No vibration at all!
Same issue here. Vibration stopped working, no way to get it to work again.
Mine also has stopped. No feedback from the keyboard, fingerprint sensor or vibration from calls/texts.
I plan on reaching out to LG today to see what I can figure out.
Anybody have any luck on finding a fix yet?
Can you guys please also share your model number- European, US, single or dual sim, bootloader unlocked or not, rooted or not, any particular action after which vibration stopped working.
Thanks in advance.
I know that this is really going to help anyone, but someone on Reddit had the same problem, then it started working again.
