hello, my device is : Lg g2 D802 (uk)
Kitkat 4.4.2 (stock)
(unrooted)
My screen broke and i have replaced full LCD and digitizer. But now Knock ON is not working, but knock off still works fine. Could there be a problem with the sensor? Wont the knock off not works too if anything is wrong with the sensor (even tho it works fine)?? So, Any help would be very useful for me , so knock on feature could work... Thanks Very Much to all
P.s. Ive have tried the Firmware update and all not working, and pls Do Not tell me to 'READ' more. I have been reading and couldnt find any answer for my KNock On to work. Thanking you:angel:
all what i know that knock off is software and knock on is hardware so your problam maybe from new screen

yeah maybe. I do replace it with Non-uk version but still D802. Could it also be that i havent remove the screen covers like the plastic transparent covers that sticks to the screen even tho touch and all still works? But the knock code still works tho.
Have you calibrated your touchscreen after replacement ?

Anyone here experiencing the same problem? At first I thought that was normal, but at some point the touch screen worked while the slider was open and I was really happy with it but now, it no longer works what gives?
am i the only one experiencing this? do you think a ROM upgrade can fix this?
Sometimes (very rarely) the screen doesnt come on and I have to reset, but nothing like you descrived, sorry...
aw! i guess i have an isolated case. thanks twolf!
it's a screen cable problem. just fix it
last week, i had the same proplem. So i sent it to the guarantee service. They replaced the cable, which is connecting the screen with mainboard.
too bad my phone doesn't come with warranty. thanks for the info guys
my phone has the same problem,and I had used many roms, and all of them have the same problem.
my screen isen't working when the keybord is closed,
aneybody have the same problem??
problem
yes i do have the same problem ... my htc niki100 was not working when slide closed ... but when i open it works fine .... sometimes when slide open also it is not working i mean the touch screen ... i removed all parts of my htc niki and i take a look at that but all was fine and i dont know what was the probelm... i think htc failure model is niki... really pissd off guys due to this niki ... if any came to know how to make work that ... just post it and for u i am thankuful..
it is hardware problem. sent my device to service center and they changed the board for free since it is still under warranty. they said it was wear and tear. so it is only matter of time before the new board suffers from wearing out again. unless stop using the sliding keyboard, but tat's the main selling point touch dual is built for =\
how much is the cable $$ connecting the lcd to the boarD?
my niki is out of warranty............can any mobile phone repair shop fix it ?

If you google around you'll see this is quite a common complaint with the Touch Dual. There seems to be a certain flaw with the screen and cable which was never addressed. I had the exact same problem & eventually sent the phone back to HTC to be fixed.
Be warned though - HTC would not fix my phone eventhough it was still under warranty. They said the problem was due to User Mis-Use. My ass it was. I argued it out with them but in the end I just paid the UK£60 to get it fixed - robbing bastards!
You all seem to think it's a hardware issue, and I'm experiencing the same issue, but only under Windows Mobile (I've tried both 6.1 and 6.5 - all sorts of various roms). Android on the other hand, works fine. :/
EDIT:
Well now it's working on Windows too. After I ran Android... SO GIVE THAT A SHOT I GUESS. o.o
Hi

1) screen doesn't work when slider is opened
2) screen doesn't work at all at times but works again after ....??? xx hours or so.

Upgraded Windows Mobile to official WM6.1 from HTC.com website.

i came in here to say the same thing.. weird. works fine in android.............
another thing worth noting is that if you keep a finger on the screen while sliding it seems to work everytime
My Niki has the same problem, when slide is open i cannot use the "send" button on the touch screen - so i have to close the slide, to send a SMS.
I bought a HTC Snap now, so my NIKI just lies in the drawer...
Sad, i like the Screen resolution and Rom software on the Niki better than the HTC Snap.
At http://www.ppctechs.com/HTC-Nike_1047/repairs.htm you can buy a HTC Nike ToolKit with special screwdrivers, maybe the cable just needs to be aligned properly, or fixed in a socket...
Has anyone tried to fix it themselves?
guys,
I had the same problem. In fact, my touch screen was totally not working at all. Some threat recon it's loosen cable so i opened my touch dual and tighten the lcd flex cable. It worked after that, but not working when slide is open. I've just changed the flex cable myself and it's working fine now. hope this help.

could you guide me how to fix it? I'm having this problem as well.
Do you have any kind of link as to how to open the niki, screws, cable, where to look etc...?
thanks!
So guys..my phone doesn't respond anymore. It was fine all along until today, I can't press on anything on the screen.
I can only get into clock recovery only, nothing else I can do.
Is there a file that can fix this issue???
Thanks.
It looks to me like a touchscreen issue and not related to G sensor...
same thing happened to me it just suddenly touch is not working cant even unlock the screen but the hard keys still works...
does this mean its the end of flashing on my hd2?
Help please
Definitely NO, just you should replace your touchscreen, somehow a common problem for this future(former) hardware-beast(HD2)

your new digitizer probably needs to be calibrated, is it genuine lg? because there are alot of subsitute replacemnts which may be the reason why is shakes soo much
I will flash via KDZ 1 version v20 but nothing changed, is any version recommend for that i mean V20a,V20b,or V20c for that ?

It's probably the digitizer itself that has the problem, like i asked? is it genuine lg? you can try flashing V20a but i doubt that will solve your problem
Somedays ago problem was shown.at 1st the bar was short...and day by day it's bigger.
now it's occur full screen.Sometimes it's just transparent sometimes mix color.
Rom-Icex 5.9
i can't flash rom....because now my display bottom side is fully black.bt touch is working.
Is that hardware or software issue?
i see some other thread he has same issue & he change his display under warranty bt nothing help, thread was unfinished.
What should i do now?
anyone?
Bump
i think u can flash the rom because while flashing the rom there is only a confirmation slider in the bottom in twrp so u can guess its place even the display isnt working as u said that the touch is working but the display is not.
see if it helps

When replacing the LCD , havent you checked if touch is working or not?
What sort of touch issue are you having? Phantom touches ? Or some portion of the screen doesnt register touches?

It could be faulty touch panel. Contact the provider or if you want to replace it, it costs 10 bucks on amazon. ( Just search by lg g2 touch panel) . Your LCD is fine.

The shopkeeper gave you a LCD with a faulty touchscreen. Always check if everything is working before you pay them.
But sometimes it might be software issue. I suggest you to try one thing, that is if you can flash a new rom, go ahead and do it, then see if the touchscreen problem still persists. If yes, then you have to replace it and get a new one.
Note that : the touchscreen panel stays on top and lcd on bottom, you replaced the whole thing that comes with the panel and lcd so theres no chance shopkeeper changed it, to remove the touch panel, you have to completely destroy it by applying heat and then slowly remove it.
Heres a video to clear it up on how to remove the touch panel : https://www.youtube.com/watch?v=eTKV0RRv2IU

Hello,
I replaced the screen of my G2: https://www.youtube.com/watch?v=yGZDcDyg2e8&feature=youtu.be
After starting the phone, everything works perfectly (normally) but after using the standby mode, only stripes are displayed and the phone is unusable. Anybody has an idea, why and if it is possible to solve the problem? Or is the new screen just broken, what I suppose.

Just replaced my display too and I have the same issue. Thing is I'm going throught the second display that acts like this after replacement. My guess would be, that there is an issue related to the different screen models. I assume (and am going to try) that a ROM reflash already helps.
Yes, could be!!! Because some shops tell you from start that those displays don't work with Android 4.xxx but i also have a doubt because , i have the same issue when i am in the recovery mode (which is kind of an independent os in my opinion, - though than a kernel update still might help in theory)
Which version do u have?
I'm very angry with the shop though, because I asked if it works with Android 4.xxx
The screen also has a physical damage. It's cracked. Neither the glass isn't attached well to the frame .
I brought it on ebay from the_phone_depot
please inforn me , when you have tried out something new.

I can confirm that this is the case. A reflash helped. I'm using Resurrection remix. Shouldn't matter what ROM tho.
Buuuut: I didn't have the issue in the recovery while i had it with the first screen. But the first screen had a bad digitizer also.
I can also confirm that it works with higher android versions. Though the seller confirmed it should be also working with android 4.4....
Thanks a lot dude!
Still a big progress!
Hi, can you tell me if knock knock function works to wake up the phone? or is there any trick how to get it to work. Thank you

Works for me. I'm aware of the issue and we know, that it's ROM/Software and not hardware dependant.
