Is there any way to disable portion of touchscreen? - Zenfone 2 Laser Q&A, Help & Troubleshooting

My phone has a problem on its screen, wich makes ghost touches (randomly, and only sometimes. If I turn off the screen and on back again, the problem is fixed for some seconds/minutes).
I have confirmed that it IS NOT a software problem: it happens on stock ROM, LineageOS and ResurrectionRemix.
If it helps, I am willing to root.
-Device is Asus Zenfone 2 Laser (ZE500KL)
I have included a photo that shows where the glitches happen. (The phone chassis is just a demonstration).
NOTE: I am not going to install Xposed, since I don't want to leave Nougat.

Erratic touchscreen behavior while plugged in, in KitKat OTA

I just installed the OTA (183.46.10.XT907), and have been playing around with it a little while it recharges. I've noticed that my touches weren't doing what I intended at all, so I investigated.
This is with the phone plugged in ...
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
... and with it not.
Sometimes, the difference is more drastic, but those are hard to get screenshots of. Is this affecting anyone else?

Doing factory reset doesn't help. It's behaving like that in snapchat and other apps too.
-system 7.0, no root, no mods
it looks like hardware issue.If you have warranty,go to the service center.If you don't have warranty... Install TWRP, try with a custom rom.If the problem presists... change the camera.I hope i've helped

Mi A1 LCD issue or firmware?

I just replaced my Mi A1's LCD and it only seems to work on the Google logo at boot, and on Fastboot mode.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
When I boot it in Recovery Mode and System, it doesn't show any display but it's responsive to touch as I can fell the touchscreen motors vibrating. I've also attached a video I've taken of the motor functioning while there's no display.
Please give me your inputs on this. Thank you!
I noticed some screens aren't compatible with custom roms on this device. Try flashing full oreo stock rom.
