Screen Flickers - OnePlus 3 Questions & Answers

Hi Guys,
Everytime I press the top part of my screen (front cam, ear piece part) the screen flickers and sometimes it shows a horizontal line anywhere on the screen and it only happens when i press the top part screen.
I ran a LCD test using #*808# and the screen is fine. It's just happens when pressing the top part of the screen. Even when I'm in the recovery mode and pressing the top part of the screen it still shows lines and flickers.
You guys think it's a hardware problem already that something might be loose connection on the motherboard?
Tia guys!

Horizontal line not responding to touch

My whole screen is responding to my touch in the sense that the screen recognizes that i have touched it i.e. buttons can be pressed and pages can be swiped left to right and up and down, However one portion of the screen with no appearence defects whatsoever just doesnt respond to touch, its the whole portion (horizontally from one side of the screen to the other) where the power off button is when the power button is held. The pixels are fine but it refuses to respond at all.
Any advice before i send it off for repair?
Ive tried restarting the phone and whatnot but it has made no difference.

Do you mean the status bar area? I had that and I just had the phone replaced.
No, you know the bit where it says power off? The whole button along with everything to the left and right is unresponsive
What's weird is that it started working then stopped again it's done that twice now. I hate intermittent errors as they tend to overlook them in repair...

[Q] Dodgy touch buttons

Im having some trouble with my physical touch buttons. They seem to stop working every now and then. If I bash the phone on my hand a few times they usually start working again. I'm guessing theres a dodgy connection inside somewhere thats causing this. There are no other symptoms though so it's very specific to the touch buttons.
I've opened the phone to have a look if anything looked loose but on the face of it everything seemed fine. However, I wasn't sure which ribbon was for what and couldnt find a diagram anywhere on the net after a quick search. Can anyone help identify what all the connections are for? In the picture I have circled the 5 main connections. So far I have figured the following:
Black circle - touch for screen
yellow circle - metal docking contacts on back of phone
red circle - not sure possibly speaker/touch buttons?
blue circle - not sure possibly speaker/touch button?
green circle - vibration motor?
If you know better please correct me. I think the touch buttons either work off the screen touch responsive connection (black circle) or the red or blue circles but cant quite figure out which.
Thanks
i know the gold colored part on the bottom left of the phone is the digitizer connector, is the rest of the screen working? if not make sure the aforementioned connector is pressed down securely

you mean bottom left in the picture I uploaded?
Everything else is working fine, no issues with screen whatsoever, its just the touch buttons. Thats why im trying to figure which connector does the touch buttons

Lg g3 screen stays black after reboot, but responds to touch

My wife's phone looked completely dead this morning, so I pulled the battery and then rebooted. The led did its usual start up pulse but the screen remained black.
Double tapping to wake, then tapping the centre of the screen where login field is, then tapping where the keyboard is, results in haptic feedback, but the screen never turns on from black.
Tried holding down + power to boot into recovery, but no idea if it works. No response from the screen.
Anything I can try? :crying:

Its the faulty motherboard chipset issue, same as me.
Take the phone apart and place a piece of plastic or something on top of the display ribbon connector underneath the battery. That solved this problem for me.
Seems to occur because the board in the g3 has too much space to flex etc in general usage.
