(solution) Ghost touch, ramdom turning on and off screen - ZenFone 2 Q&A, Help & Troubleshooting

You need to make sure its not app, rom, kernel, related, try booting in safe mode to see if problems persits if no then is app related.
If you wipe and reinstal rom and problem persist then this might be help full
Before anything else i sugest you look for zenfone 2 dissambly vids so you get to know what you are going to be doing, it is easy.
Before telling you the solution let me explain my phone symptoms:
1) Ghost touchs, be aware if you have selected show cursor coordinstes or show touch, much of the times this ghost touch doesnt appear.
2) Phone screen starts turning on and off by itself. This is very annoying I tried turning off doble touch to wake but this didnt help.
So what is the solution?
You need to open the back of the phone unscrew everything and then in the charging usb port you need to make sure that the back part of this pice doesnt make contact with the metal back plate. What I did is to use an electrical pice of tape that cut. And simple as that my phone working normal again.
Remeber to screw everything tight as possible.
Pd: i didnt took any pics but im show what part of the phone im referring
Hope this helps have a great day

Broken Power Button and WM 6.1 Help

nicematt said:
So I dropped my dash and it landed perfectly on the power button. I wasn't even that far, I was sitting down and it slid out of my lap as I was sitting down on a small chair.. maybe 2ft drop at most. Well it pushed the power button too far in and it ****ed up something to where I cannot use that button. I have, however, stuck a paperclip in the right position or the right "button" on the phone's motherboard/chip and it has turned off/on.. but that's a gamble (I don't know how I hit the right spot, but I've done it twice).
Is there any way I can fix this? I know the warranty will not cover it.. so I'm thinking about opening up the phone myself, but I don't know what I would do from there.
Also, if I wanted to flash the new 6.1 ROM, does it require use of this button? I've been too afraid to attempt this new ROM as I don't want to get stuck in a situation where I can't turn my phone off.
*Currently I'm using a program on my phone to perform a "soft reset" when I need to restart my phone.
Thanks for any help!

Oops, double post. Sorry.
You don't have to use your power button to flash a new OS. However if you run into problems, you might need to use to turn your phone back on. It's a gamble.... it all depends if you're up to it or not!
Ok, how about opening it up and fixing it? Is it possible to open it up and re-seat the power button so that it works again? Should I buy a new button from someone with parts?
You get a whole new case, which I'm sure comes with a button... or Try www.cnn.cn for parts. Or open the phone and see if you can fix it, maybe it's just an easy fix.

FIGURED IT OUT!!!!
It was driving me CRAZY!!!
So is what causes this problems is the dock mode being stuck. When you dock your phone the dock connection completes a specific circuit in the phones USB port that will tell the phone it's in dock mode. This can get stuck when you accidentally push the wall charger into the phone UPSIDE DOWN (Which I did and then got the problem) bending that pin down completing the circuit permanently.
THE FIX:
Take something sharp and/or thin like a knife and push the pin up ever so slightly. DO NOT FORCE it as you will break the pin clean off. Once you disconnect the circuit, you'll see your phone turn it's screen on. That means you did it!
Good luck! And your welcome!

Nexus has grainy screen

Hey all; I got a Nexus 7 this past December and everything was working great until yesterday.
I took it out of my school bag and when I pressed the wake button this happened:
{
"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"
}
Now whenever I wake up my Nexus the same thing happens. Sometimes it goes back to normal after a few seconds, but it continually freezes or has random slow downs.
I reset the device and erased all my data and whatnot, but still the same has happened.
Any suggestions?
What ROM are you running, stock or custom? Try reflashing a ROM (let us know if you aren't familiar with that) in case something's corrupted. Hopefully it isn't something with hardware.
This should be a hardware failure.Take it to the service.
@Pandae: Everything was stock. @GeoVali99: Correct-o, sir!
Ended up being a hardware issue so I'm getting it repaired.
I appreciate the words though!
Hi!
I've got the same problem.
Can someone tell me how to fix that Problem by my self?
I have no guaranty left...
Thanks!

Not a big deal. The LCD is fine. What happened in my case when I got exactly the same screen is that the amber ribbon (LCD to motherboard) seated wrong, and I bent a pin on the motherboard connector out of shape. You open the back cover and reseat it, but make sure you do not damage the pins. In other words do it very gently, do not force anything, and monitor it all with the help of a magnifying glass.

Screen black during calls

When I make or answer a call and put my phone up to my ear the proximity sensor kicks in and the screen shuts off. However, when I take the phone away from my ear the screen doesn't turn on again. Sometimes(maybe 25% of the time) I can press the power button to wake up the screen but usually the screen is just stuck off until the call is ended. I don't even have a screen protector that might be getting in the way.
Anyone else having this issue?
Android 7.1.1 (Build N4F26I)
Haven't had this issue and I used stock for a while, the same build as you are on.. What were you on before? Did you use any scripts or kernel tweaking apps that may have left something on your SD card? I'd look using root explorer or another file manager and delete anything you see in that folder etc/init.d and reboot. (Screenshot attached) If you have nothing in there and don't have any scripts active or kernel apps controlling your screen off I guess it could be faulty hardware. (Power buttons always are jacked up on Nexus devices. I have to hit mine a few times to get it to work...) Maybe try a factory reset if nothing above applies or works that's what I would do. Copy all your stuff to your laptop or a cloud and wipe that baby in twrp. Format data then go to security settings and encrypt again if that's what you want..
Edit
If none of that works I'd contact Google and ask for a replacement.

Screen dead after rom flash

Hello, i wiped my phone(system,data,cache) and flashed aquarios rom, but after rebooting my screen was not working, system booted up and i can hear volume and vibrations. But i cant locate the problem... could it be in hardware? I tried to disassembly phone and clean contacts and make sure everything is good connected. Also tried to wipe everything and flash stock 7.1.1, then 6.0.1, and still the same problem. Anyone got any idea? Should i replace the screen? Thank you

Maybe your GPU died? it's part of the CPU chip, and we know that unfortunately this CPU (SD808) is prone to fail on this device, due to heating-cooling cycles that creates cracks in the CPU chip substratum (looks like LG miscalculated the coefficient of expansion). I am saying it based on that you were flashing your device (it produces lot of heat and CPU use), and then, after a reboot the issue showed up.
But it can be faulty screen, this would be very weird (since i am assuming that you did not drop it during the flashing process or something similar) but not impossible.
You cleaned the connectors on the motherboard with isopropilic alcohol? i had a similar issue on my N4, and it was the solution.
Anyway if i were you, probably i would get some chinese and cheap screen replacement, at least to discard the faulty screen theory.
Thank you very much, i wouldnt think it could be gpu problem, but it looks like it is. I am going to give a try replacement screen. Taking into account my usage of phone, it would explain the dead gpu.
