I accidentally opened the cover to check due to white lines appeared on the main screen. Somehow the EPD finger sensor not working after I closed back the cover. I tried factory reset but the back screen still not working.
Can anyone help. Your help is very much appreciated.

Has anyone installed the HC SP300 screen protector - if so does your proximity sensor work.
I noticed today that when i make a call, the device blanks the screen after pressing the send key. Putting it to the face and away does not make the screen come on. I'm guessing its the screen protector as i just did a hard reset and still not working (although it did when i got the phone.
I install the HC Sp300 on my device and the proximity sensor still works fine.
OK thanks.
Guess im going have to remove it to find out if it is the screen protector. If that doesnt work, i guess i have a dead sensor?
I have the same problems. It seems to be working, but with the more light.
I had the problem of the black screen when a call connected.
To solve it, i cut a small section near the 2 small holes in the top left corner.
Now it works as per usual. I think its a case of 'if you dont align the holes on the screen protector precisely', you will get this problem.
I've searched a good bit and wasn't able to find any information regarding the exact problem I'm having.
Bought a used G6 for starters
No water damage indicated by the sticker
The phone works great on the home screen and app drawer
I turned on dev mode to show touches
When you're in the camera it will stop responding to touches, you can still take pictures using the side buttons. The screen will become responsive again after a couple minutes. This whole time you can take pictures and the screen is functioning just not responding to touch
This happens also when you're loading web pages, even a Google search the screen will stop responding to touch and then eventually start responding again for a short while till you load another page or start moving around the page too quickly it seems. However again the screen is functioning, video previews are playing, just no response to touch.
Loading a game like Asphalt 8 the phone doesn't respond to touches until a couple minutes after the game has been fully loaded.
Even after a hard reset/factory reset the screen will sometimes be unresponsive upon the initial welcome/setup screen and then it will become responsive and you can go through the whole setup without an issue.
Any insight? Any suggestions? If I can't figure it out I'll just get rid of it but it's in great condition a shame it just doesn't function properly.
Thanks in advance!
Looks like some sort of hardware issue...
But before you start to worry...
This might sound like a stupid question but have you tried cleaning your screen with some cleaning solutions?
Sometimes dust mixed with dried sweat can cause severe touch responsiveness issues even if the screen looks like it's clean.
This is an older thread, but maybe I can help someone.
I replaced a touchscreen on a LG G6 and saw that the touchscreen did not work if the back cover was not mounted correctly and the data transfer between the phone and the fingerprint sensor was interrupted. This may be a common problem for users because the connector is small and the back cover is attached with a double-sided tape nearby this connector. It seems that the touch screen is disabled by the phone software without the back cover.

Thank you so much for this comment!
My gf phone had problems lagging and becoming insensitive to touch, the problem got worse and worse, almost never responding anymore. Performed a factory reset etc, didn't help.
After reading your comment I tried pushing on the back cover while swiping. Now I'm able to revive the phone after pushing hard on the top and bottom left corners, of the back cover.
Thanks a mille !
Lg g6 has back panel from glass and under it you have contact for fingerprint sensor.Somehow if the back panel is loose it can cause touch fail,and you cant use the device touch function!
--->FIX:
So you will have to turn screen off using back button,and then try to press back glass on left and right side of the camera lens !
Then simultaneously press the power button and try to use the touch .
If it does not work tru again around camera lens and turn off screen each time you press the back glass!
For me it worked !
I want my second screen to be on when the main screen is off. Second screen works fine when main screen is on. When I turn off the main screen, the second screen changes for a split second (you know how it changes to signature/time?) and then goes black. BUT it still works. From memory, I can swipe to quick toggles and turn on/off my flashlight and it works. But the second screen stays black.
This started after I replaced my cracked screen. After swapping it with a replacement, I was having a bunch of issues with the proximity sensor (second screen off when main is off, knock on wouldn't work, fingerprint wouldn't work, sensor app always said 0cm). I fixed these by moving over the little rubber gasket from my old screen, but the second screen still doesn’t work.
Second screen daily timeout is disabled. I wiped dalvik/cache from recovery. Rebooted multiple times. Opened it back up and reconnected the display ribbon cable. Tested the display and sensors from the hidden service menu.
Any advice?? I'd like to troubleshoot further before doing a hard reset (I have so many mods installed lol). This second screen is why I haven't upgraded the phone yet...
You forgot to put the rubber gasket for the proximity sensor back in. Without it, you'll see exactly the problems you are now. Search eBay for LG V20 Rubber Gasket Holder and you'll see the part I'm talking about. If you put it back in it will fix these issues. It's a common problem with the LG V20 screen repair.

Hey guys, just got LG V35 updated it to android Pie, everything seemed fine, but i can't normally unlock phone. On main screen i can double tap and it locks, however double tapping again, doesn't unlock phone, as if screen froze. Also fingerprint button doesn't work either, i mean i need to press it twice slowly and only then screen turns on and shows lock screen, always on display also doesn't work. After simple restart those features work, but after a minute, same thing happening again. Also noticed, that if someone calls, screen is also unresponsive. Got phone couple days ago. Any solution ?

i had the same issue when i got mine. i think the screen protector i installed was the issue-it only had adhesive around the the edge and started to come off. i returned that one and replaced it with another make and haven't had the "knock on/off" issue since. good luck

I agree with tomdi1999 and also have used the adhesive around the edge screen protector but they interfered with screen touch sensitivity, it is as if having a couple of fingers touching the screen permanently while trying to double tap or unlock the phone via power button. If you have any glass screen protector, try removing the screen protector and double tap again to see if it fixes the issue. If you are not wanting to remove the screen protector first and want to do some troubleshooting, try run touch screen test via the hidden menu (assuming your v35 is AT&T version) by dialing *#546368#*350# (Be warned that some options in this menu can really mess up your phone so don't go around messing with options in this menu randomly) in the phone dialer. In hidden menu select Device Test -> SAAT -> Service Menu - Manual Test -> Touch Draw Test. If, with screen protector on you are having trouble doing this test, remove the screen protector, clean the screen, and do the test again. If you still have trouble with touch screen it is probably a hardware problem or could be software problem but unlikely though. Also, place a test call to someone and slowly place your hand to cover the ear piece and proximity sensor area to see if screen goes dark. This is to check if your proximity sensor is working properly because if it is not then it could be the reason that double tap to wake is not working, although it doesn't explain why your power button is responding slowly, that points toward the phone processor being busy due to ghost touches such as due to bad screen protector or just a faulty power button (but what are the chances of having a faulty power button and double tap to wake going bad at the same time lol?).
I remember that years back on LG G4 double tap function would stop working if you had the screen replaced or sent in the phone to LG for repairs such as repair for notorious bootloop issues and it turned out that there was a small rubber piece that went around the proximity sensor that people were forgetting to put back when replacing screen or doing other repairs which basically broke the proximity sensor. Proximity sensor is suppose to disable screen wake up due to accidental double taps such as when phone is in pocket but if proximity sensor is malfunctioning it will not let phone wake even when you double tap to wake it.
If you figure out what was wrong and/or fixed your issue, please do post back so it can help others. Thanks.
Edit: If you are looking for a good screen protector try Skinomi or Armor Suit wet screen protectors. They are not glass and are a pain to put on but once you install them and let them dry, they are awesome.
It helped me thanks a million!
wouldn't think ever it was the screen protector, thought one of my apps...
I've removed it and it was back to normal.
thanks again
Hello guys,
I've got a problem, starting yesterday, my Samsung S10 Plus (G975F on ASJG firmware) has some touch screen issues and proximity sensor issues.
What is happening is that when I start a call and I place my phone near ear, it turns the screen off, but when I move it from my ear, it stays off. This issue started yesterday.
I removed the screen protector, did factory reset via ODIN (flashed clean firmware with factory reset).
The test on star#77692# works (proxy sensor test), when I place my finger it turns on, when I lift it it turns off.
Thank you for your help!
perhaps try cleaning the screen. I hear there is a number you can dial to run system tests but I am not sure if it.

Just to finish the thread.
I had to replace the screen due to the fact a brand new phone (3 months old) had its display unglued somehow and the issues I described started to appear.
Now everything works...huge dissapointment in Samsung screen quality.
