Can't turn on screen sometimes

Is anyone else having issues with the screen not turning on (at all) sometimes? It seems to happen after the device has been in deep sleep for a while. The only solution is to hold the power button until the device reboots.
It used to happen on 4.4.2 as well, but I was using franco kernel and ART then, so I thought it might have been related to that.
Now I'm using everything stock on 4.4.3 and I'm still experiencing this issue at least 2-3 times a week. I even did a factory reset, but the issue persist.
Could this be a hardware issue with my device?
Anyone got a clue? I should also mention that this never happens while the device is charging.

Screen Glitch/Flickering - Software or Hardware Issue?

I've been having this problem since the other day. The day before that, the phone's just working perfectly fine, tho, when I woke up in the morning, the phone just suddenly got this screen glitch. It only seems to be having a glitch in dark backgrounds... But given some time, the glitch disappears, but then again, if I turn off the display and leave it some time, the problem reappears.
Please look at the vid.
I don't think it's a hardware problem since the splash image isn't affected and the glitch seems temporary, but changing ROMs doesn't help. I haven't tried the stock firmware tho. Gonna download the stock fw and try it and see if the problem still persist.
Hi,
It's a hardware issue.
It's not related to any ROM you're using.
I've same problem as you and I decided to return it to stock and sent it to the nearest Asus Service Center (in Makassar) via my local seller because there is no one here in my location.

its not hardware issue if that not happen when you use screen recorder.
give a try then...
@baonxxx
This isn't related to software. I had this screen glitch even on stock (applies to everything: Splashscreen, etc) and caused difficulties on normal usage.
By general you can trigger this screen glitch by let the phone heating for a period of time, like let the phone idle for hours, charging, or let the screen on around the time. *only on affected devices*
You may need to read OP once again.

as u can see in the video , it doesn't really affect the splash screen, tho if flashing back to the original fw doesn't help, then I may need to get it to Asus Service Center for them to check.

I know that, but when the screen glitch becomes worse, it would happen on everything.

hhmm, not really everything, only glitches on dark backgrounds... seems like the screen on my phone's having a problem on dark backgrounds.
it is definitely a HW issue. did your phone ever fell on the ground?
this usually happens when there is loose connection between the mainboard and the display.
if you haven't void the warranty, send it for repairs, otherwise open the phone and fix it yourself (just detach and properly reattach the display connector, and make sure it's grounded properly).
@pecholino
Only unlocking the bootloader with official method provided by Asus could void the warranty.

damn it's a HW issue and it's getting annoying... gonna send it back for repairs... damn I didn't even dropped the phone once, so much for ASUS.
It happens with me too. On stock firmware. But is very rare and temporary. Turning off the screen and then again waking up solves it.

it happens to me on stock as well. Same as yours turning off the screen and waking it up makes it normal. so it's not a firmware problem? or is it?

I don't think this is a hardware problem as so many people are having this problem.
This problem happened to me the next morning after I updated to 2.20.40.168 I didn't drop me phone in between the time I updated and the time I first seen it happen. I've already sent my phone in and Asus replaced my motherboard. I got it back and problem was still happening.
The problem may go away for you if you set Developer Options, Disable HW Overlays but the setting does not seem to persist after a reboot.
quick settings
I noticed another remarkable phenomenon. When I open the quick settings, the defect is gone. But I only can operate in the quick settings, nothing else.
The screen freezes until I open the quick settings. -
I have reinstalled all software, even the boot partition. The defect already occurs in the splashscreen and fastbootscreen. -
I have opened the plug connection to the screen and connected again. -
So far everything in vain. -
ASUS claims, it is a defect on the motherboard. - I am afraid they are right.
It is a hardware issue. The problem is with the screen, precisely, the multiplexer on the screen. But since it is a part of the LCD itself, you will have to get the entire display module replaced.
Replacement displays are available on eBay/Amazon and you can get instruction guides on YouTube.
If your phone type z00AD Try downgrade your rom only to 2.12.40.11.. its solved my problem..

Touch no responsive after call

HI, guys. You my only hope. 6 month ago a replaced my screen with screen from Ali. Sometimes I have problem, that after call touchscreen became unresponsive screen is working . Reboot with pwr + volume up do the job. I do some research. Proximity sensor is OK, even with disabled touch, thanks OTG cable.
Problem is unstable. O can't repeat it. Happens Suddenly.
This problem is rom independent. But I used only stock, and now on stock based custom
Locked bootloader
anyone? =(

i have the exact same problem with you and i think is screen related.
i ll perform the proximity sensor check and if it is not the source of the problem,i ll take off my screen,give a cleaning at the connections and put it back on, to notice it s behaviour.
hope i won t break my screen cause it happened before:fingers-crossed:
my screen has started un gluing from the left side of the display and screen is lifted upwards ,i just mention this for the possibility of causing a problem with those freezes during incoming calls,but i can t think of anything.
probably i need to order a new display(not from the same seller of course) cause it is a little dim too,if it s not fixed after trying those i really don t know what i will do with my phone,it really gives in my nerves with this problem(otherwise i m very satisfied of owning it).
i ll come back reporting after making my tests...
EDITroximity sensor check OK,no problem.
cleaned the connections of my screen and i have only 1 freeze after 40 calls,but is still there and is only a day that passed..
i can t target if my problem is hardware or software,i ll flash stock lollipop with flashtool and wait for some days,but if it appears again what should be my next step?
any ideas welcomed..
EDIT 2:after five days on stock 5.1,problem seems to dissapeared,so i supposed it is related to an app...
EDIT3:till now everything is OK.

Touchscreen issues

Hello All,
I know there have been a lot of touchscreen issues with the G4 in 2015 but is it still happening for some users? The touch screen issue i have been having is very intermittent and only occurs when you wake the devices up. So when you wake the device no touch input is detected. I can tap any where and it will not register any touches. I will then put the device back to sleep and wake it up again, then it'll work normally.
Not sure if this is normal but is anyone else having this issue? Should i be concerned or RMA the device or is this more of a software bug?
I can use all the diagnostics test tools and it'll pass since the issues is not lagging or missed touches.
Thanks all!
Try to reflash the firmware via lgup or lg flashtool
I have this problem too but it seems more random than just when the screen wakes up and has occurred while I've been in the middle of doing something on my phone. It's simple to solve by turning the screen off and back on again but it's very annoying when it happens.
Yeah, that sounds really annoying....Wonder if it's a bug. Going to try a reflash and retry. Hopefully it'll solve it.

Touch screen issues - July Update

And another problem with the July update (the most f****d up update ever! lol)
After fully charging the phone (with the OEM charger) I noticed that the touch screen became very unresponsive especially with the navigation buttons. Strange but I never faced such a problem before this update.
Hello, I have exactly the same problem.
The screen is less responsive and very difficult to use.

The first thing you should do is factory reset.
No touch on LCD. miA2lite
I have tried hard reset that but it's still the same. No touch at all. The bootloader is locked. So just want any solutions. Or answers. . I have tried another screen. And that doesn't work either. So maybe software related. ?
same problem with august update
I think I will give back in warranty
New mi a2 lite here with the latest update . The keyboard is so slow . i need to press twice on letters especially on the edge of screen(i can type faster on my older samsung s4) .same thing for scrolling sometimes fast and other times slow
I recommend both of you to try "Force GPU Rendering" option in developer settings, in my case after applying august update the problem still exists but not as worse like before /in July update mostly/. The strange thing now is the problem not shows up after every charge, maybe it's just hardware issue in my case, maybe after charging the phone become too hot and the issue shows up / f****d up display cable or so../

I think you need to open a new thread since your situation is different from the OP.
Has anyone been able to resolve this issue? It's extremely frustrating, especially since the phone is generally preforming pretty well apart for this problem!
Since July unfortunately still the same issue
I solved my Mi A2 lite ghost touch problem by turning on battery saving mode. I tried all other methods before it and none of that worked. May be the problem is with some background process which turns off by turning on battery saving mode. I hope this method will work for you.
