I'm attempting to run a google pixel 3 without the physical screen. The phone will be used in remote management, so I have a remote management utility installed on the device as well.
Everything works flawlessly when the screen is installed - all apps and configurations work as they are intended. However, once the screen is removed, the phone doesn't work. On a pixel 3a I was able to attach just a ribbon cable for the screen without the actual screen, and when I pulled it up in airdroid, it would only display a condensed screen about 1/3 the height. On the Pixel 3 it doesn't load up at all.
I've connected the phone to my computer with USB debugging enabled. Without the screen it shows up in the devices list. But with the screen it doesn't even show up in the devices list. The only way to make the phone operational is to remove the battery cable then restart the phone. About 30% of the time it displays a message upon boot "This device failed to boot, do you want to factory reset", with an option of "yes" and "reboot" (selectable through the volume and power buttons).
Also of interesting note, if I power on the phone without the digitizer connected, I can use AirDroid just fine, but it won't register my clicks on the remote view screen. Which leads to believe the phone is registering the hardware of the screen and digitizer upon boot.
If I disconnect the digitizer and LCD after the phone is booted up, I can attach them both and it'll work. It's just when they're disconnected from the phone during the initial boot phase.
I tested this with a Galaxy S8 previously, and that phone worked just fine without the screen attached, and ran fine that way.
Does anyone have any ideas on how to "register" the hardware correctly? I'm not certain that's what's happening, but it appears to be something with the hardware not registering correctly, or something like that. What's odd, is that it doesn't work even with the ribbon cables attached. It requires the full screen to be connected to the ribbon cables.
I've searched up and down google, but there doesn't appear to be much information available on this, as it appears to be a very specific problem which not many people encounter.
Thanks!

Hello,
My phone was waterdamged and stop working completly.
I opened the case and tried to dry it.
after 48 hours of trying various stuff, there is blank screen, but:
1. The phone is booting fine, charging led is working.
2. Using Wondershare-Mobilego, i can backup all the content.
3.The touch interface seems to be working fine, i can see the menus via mobilego duplicate screen (can open the sms box or whatsapp and etc.)
4.Incoming messages keep coming...
I`m so frustrated that i`m using the phone blindly or like remote desktop.
Is it software of hardware fault?
THANKS

After water damage you can only expect hardware damage. to verify - when turning on the device, do you see anything on the screen? you can also reboot to bootloader (via the key combination or via the command adb reboot bootloader (and to reboot back to android use fastboot reboot).
If the bootloader shows nothing, 100% hardware (although there is really no need to check, probably is). You can try changing screen, but the problem could also be in the socket (but I think if it were the socket the phone would not even boot). Worth a try.
Thanks, but no good...still blank screen - no display.
As i mentioned, the phone is functioning well (as seen at duplicate screen).
When you offering to change screen, you mean the lcd touch digitizer only?
I don`t need to buy the screen itself, right?
(I can`t parse outside links yet from ebay)

I mean the LCD itself. If touch is working, the problem is the LCD itself, not the digitizer.
You right, it seems that the touch working fine.
You think that a LCD display screen replacement would be the best try? can you paste a link from ebay please?
Hi guys!
My Pixel 2 turned its back on me yesterday. When I woke up and took my phone to check the notifications, the display wouldn't turn on. I knew the device was working, since the fingerprint reader vibrated, but thought that either it's the BSOD I've been reading about on the internet, or the screen went bust totally. It seems neither is the case.
After some tinkering I know for sure that:
1) the device itself is fully working - software works, calls can be made, assistant works, it's fully accessible with adb, it responds to all input, charges normally
2) the touch input works just fine, I can blindly use the phone, but cannot see anything on screen at all
3) the screen does not work anywhere, not only when the system is booted up - forced reboot (power + volume down), reboot to recovery mode with adb, charging with phone powered down - everything works, but display won't ever turn on
4) it's not an issue with proximity sensor - using adb I was able to check that proximity sensor works just fine during calls, and normally returns a non-active state. Also, the screen is theoretically either on or off, depending on device state, but with no visual difference
Everything drives me to think it's a hardware failure (though I've seen failing touch or failing display+touch, haven't seen failing display with working touch yet) and I've already filled na RMA and I'm sending the device back for warranty.
The whole thing was so sudden and not expected though I thought I'd share and ask if anyone had experienced something similar? Is my reasoning that it's a hardware error valid, or maybe I'm missing something and there's something more I can try?
Cheers!

Hi all,
I dropped my OnePlus 6 and the screen is completely blank. The device seems to be working(vibrations and screen unlock lock sounds)
I am on Stock OOS with the latest update installed, completely unmodded(bootloader locked, no TWRP installed, no custom ROM)
I thought I had USB debugging enabled but it seems I have not as 'adb devices' says unauthorized.
I need to pull some data from the phone, what are my best options in this case?
I am ready to flash any TWRP/custom recovery to do this.
Biggest problem is screen is completely blank.
Thanks
Did you check whether the touchscreen still reacts to touch input? Although not the easiest solution but you might try to either authorize it by tapping on the screen multiple times or compare screenshots of where it should be to authorize it. The "Allow" button should be a little bit down further from the vertical center and a little bit to the right. You could just tap dozens of times unless you press "Cancel" on the left side.
You could do this with TWRP as well but there is a risk you tap on the wrong parts and maybe wipe your device accidentally.
Unfortunately, the OnePlus 6 doesn't support HDMI outputs and DisplayLink adapters require an app on the device to work.

@sigma_p As suggested by Macusercom, you have to somehow enable adb. After that you can try
Scrcpy tool to display your phone on your PC and retrieve your data.

Good luck?
Screen is black and no combination of button input will do anything. Unit will charge and CPU is running since it's sending battery and location data. Unknown if unit may have been damaged/dropped. Have ADB. Help!
The phone is making normal notification and ringing sounds. I managed to locate and run Scrcpy.exe, a "carbon copy" program that lets you remote-in to the unit using a computer keyboard and mouse and ADB over a USB connection.
Invoking Scrcpy.exe I was greeted with an image of the "normal" phone screen (what I should be seeing on the phone's display if it wasn't black.) After about 10 seconds the phone-screen on the computer turned black and I was back to square one. Tried again and quickly used the mouse to trace my unlock pattern, this worked. Using the computer keyboard, mouse and display with Scrcpy.exe I was able to read email, check voicemail, I presume I could do anything I would have been able to do on the phone's touch screen (unknown if the touch screen still works).
Unfortunately I haven't yet been able to coax the phone's screen into displaying anything other than black.
It's beginning to look like the screen is FUBAR -- or is it?
E: The home key, power key, and the touch keys to the left and right of the home key all work. Ran Samsung diagnostics by pressing *#0*# . All diagnostic tests passed except for display and touchscreen.
Will attempt to drain the non-removable battery and try again.
Cured it by draining battery!
The battery was allowed to completely drain and was reconnected to a charger, resulting in the screen coming back to life!
Hooray beer!

Hey, so my phone's screen recently broke, and it was still working perfectly in Samsung DeX mode. However, I made the mistake of disabling it because something I wanted to do required normal screen mirroring. Now, when I plug the phone through HDMI, I see a padlock on the screen, which normally requires me to enter my pattern to unlock the phone and have the screen mirror normally (but the screen and seemingly touch aswell are broken).
- Samsung S20 FE
- USB Debugging is disabled, so i cant use scrcpy
- I am able to feel vibrations when using a mouse, so maybe there would be a way to enter it blindly, but the pattern is too complex for me to do that
- I don't think I have a normal PIN but I don't recall, some people said pressing space twice on a keyboard then entering it could help, no luck
- I'm was able to see the device once in sideload mode, probably through recovery mode? (screenshot below)
- I currently see the device as unauthorized (2nd screenshot)
I'm pretty much open to any way of doing this, even disabling the pin would be okay.
Thanks in advance!
Managed to fix this using a windows drawing pen, finding where the dots for the patterns are located with vibration, and mapping them on a piece of paper.
another way would be connect TV or monitor with HDMI adapter and connect usb mouse / keyboard

The thing is, the pattern doesn't show on the external display.
All you see is a grey screen with a padlock and the time.
If you have a PIN though, that does work cause you just have to hit space twice, type it in then hit enter. Easy even if you can't see.
