[Q] Screen problems - G2 Q&A, Help & Troubleshooting

Hi,
Today I got very strange behavior with my G2.
It started with knock on stopped working and continued with strange notification bar behavior.
When I am trying to pull the notification bar down it sometimes stops at the lower of the screen and get back up, it takes few tries but at the end I manage to put in down.
I thought it is software problem and tried to do factory reset and flashed different roms but those problems are still exist.
I don't have any screen protector so that's option out too.
Any idea what the problem can be? last time I had similar problem I made a screen replacement (it was 2 months ago) and today it happens again. I don't want to replace the screen again.
Thanks for any help you can give.

touch screen problem

when i touched the screen using my finger thumb in certain area of touch screen(middle), the start menu automatically drop down
i tried my friend's unit as well, also got this problem. anyone got this problem?
Yes, i have to this problem!
how u gonna solve it? seem like this model got this problem...just it seldom happen or frequently happen
I've the same problem too! But I've send it to HTC care (I'm in HK) to repair two times. First time they change the mother broad but the problem's still there; then I send it back the second time, they change the screen as well.
I've got it back for 3 days and the start up menu didn't pop up itself. Hope it won't happen again.....
I have been experiencing the same problem for some time now.
I've had this device for about 5 months and I have been treating it very nice.
Whenever I touch a certain area of the screen (which I haven't been able to figure out yet), the Start Menu pops out, which is very annoying, to say the last. It especially drives me nuts when trying to compose something using CooTek's TouchPal.
All in all, I do not know whether this is a hardware problem or not. I'm not very sure this is covered by warranty...
same problem here, touch screen changed 2 times by htc
i take to service center, they help me changed the motherboard as well but the problem still there...i think need them to help me change the screen as well...
second changed the lcd touch screen, still got that problem but less already
happen once a day sometimes 2 days once
anyone what the problem?

HD2 Touch Screen Not Responding

Hi Guys i hope somebody who knows about capacitive touch screens can help me! I have taken my HD2 apart to fix a smashed camera lense. On removing the back cover i used a small screwdriver to prise off the back case and unclip it all round. It came off with no problem, i fixed the camera and put it back together. When i turned the device back on the touch screen isn't responding to my finger on any screen. Like i turned the touch screen off! The hard buttons still wok but nothing from the screen. Nothing looks damaged (I.e the glass isn't smashed). I seem to think i might have damaged something when prising the cover off with the screwdriver. Please, any suggestions would be really helpful!!!
Can anybody out there help with this? I am currently without a phone :-(
I have exactly the same problem, but it happened from nowhere. I didnot unscrew anything. Please Help
Check the flex cable.. this part are very delicate.

same problem
ive got the same problem, mine just stopped working, i performed a soft and hard reset, removed the battery still nothing. it worked for a moment but once locked it stopped working again, only the hard buttons.
same problem but it works on and off. basically the screen will respond until the phone is put into hibernate. the after that id have to push the phone button and end button back and forth until it responds
Same Issue independant of ROM
Same issue here.
Funny thing is it started a week or two ago randomly out of the blue.
Same scenario:
lock the phone can't get touchscreen to respond for unlock
Judging by these posts everyone started seeing this about the same time, maybe it's a software issue or background app .
Help!
I have same problem. It can work for a couple of hours or in 1-2 days then just stop responding, almost every time when in hibernate. Lets just hope it's not hardware failure.
This started happening to me this morning. Out of 50 tries, managed to unlock the phone three times only. This happened out of the blue, right after i removed my phone from the charger.
Have soft reset, hard reset, reflashed ROM, but the issue still remains.
I really really hope this is not a hardware issue.
Does anyone out there know how to solve this? My phone is virtually unusable right now...
Same problem here, I've been testing for about 2,5 months now and today I've sent mine back to HTC . I think it's a hardware problem, tried everything from hard resetting to reflashing. When I press the HTC logo and keep it pressed the screen does respond again. Conclusion: hardware problem.

You're probably right.
I've also tried everything. But kind of strange that if I lock when not on home tab it seems to work. And the screen, almost always, reacts as it should as long as I just dont' lock it.
I just started to get this issue. touch screen works fine until it hibernates. reflashed, still happens. found this in my search:
htcphones.net/htc-hd2-problems-with-touchscreen/
just got off the phone with tmo. they are sending me a new one.
Yeah, it happened to me as well. I opened a new thread like a month ago explaining the problem: http://forum.xda-developers.com/showthread.php?t=710282&styleid=15
and I contributed in another one concerning the same issue here: http://forum.xda-developers.com/showthread.php?t=708530
Summing all up, it ain't caused by a software or a ROM of some kind (at least in my case) because soft and hard resets didn't solve it nor did the flash of a stock ROM. The most probable cause is a digitizer (touchscreen) defect that appears randomly and totally out of the blue. The only thing to do in my opinion is to send the phone in for repair, which I did. It came back with a check mark on "calibrated screen" checkbox. As of now phone's working fine and I hope they solved it even though I read of other people who have had their leo's screens completely replaced..
A curious side note: htc care reset to zero my phone's call duration timers..
I'm not sure if it's the screen. In my case I think it's the connector from the screen to the motherboard, because pressing the housing seems to help.
But let's see if HTC is able to repair it, I hope they are, because the problem is so random they might not even see it
After losing functionality on my touch screen for a week, finally decided to send it in. Took the trouble to revert my HSPL to original and Stock Rom.
Repair should take about a week. Now I'm stuck with an ancient Nokia 6230i for this week. I feel so lost without my ppc. Have had one for as long as I can remember.
Hopefully the phone comes back okay...
I've had so much problem with the screen not responding so I did all backup then reflashed, hard reset to put the device back to stock. Did this during the weekend, I even fired up my old iphone 3g to have as backup phone.
All set today to go to the store and have it repared under warranty.
But since Sunday evening it works perfect. I've been testing it a lot and the screen has not stop responding even once.
This might be just temporarily but does anyone else experienced something like this?
Mine sometimes worked well for hours... days... but eventually the problem came back.
Mine died on me when I was actually out of the country (stuck in Vietnam without a phone). It would work for 5 minutes, then stop for hours. I would have to switch my phone on and off for a couple hundred times before it worked for another 5 minutes...
Got so tired of it that i sent back my HD2 for warranty repair. Expect it to be back tomorrow (or Friday at the latest). Hope there's no further problems with it.
I hate to say it, but the HD2 is known for its highly defective touchscreen. Even when it's working, a lot of people experience strange and bothering events, such as the touchscreen "touching" itself, a very high/very low screen sensitivity all of a sudden, the tilting of the screen to one of the four corners of the device and so on and so forth.
With a device so expensive one would expect it to work flawlessly. Seems to me that HTC doesn't think the way we do...

[Q] Touch screen issue

Hi,
In last week I got very strange behavior on my G2.
It started with knock on didn't worked as it should be and stuck few times and continued with strange notification bar behavior.
When I am trying to pull the notification bar down it sometimes stops at the middle of the screen and get back up, it takes few tries but at the end it is working.
I thought it is software problem and tried to do factory reset and flashed different roms but those problems are still exist.
I don't have any screen protector so that's option out too.
Any idea what the problem can be? I don't have any warranty and I am curious if anyone got this before and maybe there is a solution before I will go and get screen replacement.
Thanks for any help you can give.

V20 Black Screen

Woke up this morning and started using my phone, noticed that the screen became unresponsive for a few seconds at a time and then I saw some gray horizontal lines.
Did a battery pull and restarted the phone, however, the screen is completely black and I can still hear the boot sound.
It requires a pin to start completely and I can feel the vibration when I touch the location of the back button (the only navigation key available on the pin screen).
Since this started happening I have tried restarting several times and I have seen the "LG splash screen" once, it freezes, the boot sound plays and the screen goes black once again.
The phone is unrooted and has never been modified any at all. It is the US996 variant.
Has anyone ever faced this issue? Could it be the display itself and maybe a replacement LCD will fix the issuse?
UPDATE
Got past the pin screen and think the phone has fully booted, fingerprint scanner works, I can touch the navigation keys and get feedback and I am still getting notifications.
However, the main screen is still blank and the second screen shows the time surrounded by static surrounded. I have attached a photo.
Sounds like a hardware issue.

Hi Have you fixed the issue?
Hi
it looks like a corrupt bootloader,
Was it rooted? try to press with the phone off volume + and plug in the usb to enter in download mode, if you enter download mode go back to factory

Had to send it in to LG to have it repaired
Oddly enough once it was returned the problem reoccured a few weeks later after using an aukey quick charge3.0 charger that I had. Which was when it happened the first time but I didn't make the connection until the second time around
I got rid of the phone though
No more LGs for me, I haven't had much luck with them
Throw that charger seems like or the cable or the charger itself gone bad ,one charger killed 2 of my phones not diferent brands

Touch stop working after turning off and on the screen.

I've been using the PH-1 for a year and a half and its great, but a couple days ago i would unlock the phone via fingerprint (as ussual), it would unlock but the touch wont work, so i factory reset the phone and still the same, remove the case and the screen was loose (almost complete), but the cable was well connected on both sides so i got the screen glued, but still the same.
Im using Android Pie (from day 1) with March update (updated like a week ago), in order to use the phone beyond what Google assistant can do i have to reboot the phone (using power and volume buttons) to get the touch to work again and dont let the screen go off. Sometimes after rebooting the touch works even if i turn the screen off and on, but i think its just luck.
You guys think it might be a software issue? or hardware issue? because i don't live in the US or CA, so i would have to wait a couple weeks for the screen to get here and i would'nt be able to return it in case its not a screen malfunction.
I really don't wanna change my phone, i love the PH-1.
EDIT: i just replaced the screen with a new one from fixez.com and the problem persists, i think april's update broke something. is there something i can do to check the software? Pls help.
I rooted my phone and almost the same thing happens. I turn off the screen and turn it back on and the touch is unresponsive. Howver, ONLY the apps left on screen are unresponsive. I can still pull down from status bar its weird.
Update 1: I saw u mention fingerprinting. I removed mine and somehow it seems to have stopped. I'll use it for about another day or 2.
Update2: Well it doesn't. If my screen times out with an app open. The app is unresponsive upon waking.
