[Q] part of touchscreen becomes unresponsive suddenly?

Hi,
I own this HTC incredible for several months. The touchscreen's been fine. No unresponsive spots. But today I just noticed there appear some unresponsive spots. I was playing Air Control and found couldn't touch the pause button.
So I decided to test the whole screen in Draw! app. Here's a picture of what I got. There two corners that do not response. What should I do? Did anyone encounter the same problem? The dark corner means unresponsive areas which I cannot draw. Please help!
I'm using Skyraider 3.5 rom now but I did flash to other rom yesterday, then flash back(restored in rom manager).

This the picture I drew. Hope the attachment can be seen.

Well, still can't see the picture, but is sounds like a hardware problem. I'd run the RUU and make sure you do s-on first. Then take it in to verizon if the problem persists.

Thanks a lot for replying! the problem disappeared! I don't know how. The problem persisted after I reboot the cellphone. But it fixed magically.
Dunno why it's so hard to put on a picture??

Touch panel trouble

Noticed something strange for the first time , screen is laggy and not responsive while charging the phone , I think it maybe is the kernel as its the first time to notice this , It happened after flashing franco-r6 kernel and iam using insert coin 6.3.1 Rom
Is this normal ?

You flashed a ROM, You're not stock therefore you need to consult the dev of that Rom about the issue.

To be fair, I had this issue on stock.. so it probably isn't a problem with the ROM

Yep I get this issue at times as well. Especially when I've left it to charge for a while and try to perform a pattern unlock. Happens about twice a week or so. Screen returns to normal after 10 seconds or so. Weird.

+1 this happens on stock roms all the time. it's intermittent, and often can be temporarily fixed by switching the screen off then on again.

I'm about to send my phone in for repair because of this problem. I actually have a dead patch on the screen which is intermittent. If I go to Developer Options > Pointer Location, and then trace my finger around the screen, I can see the patch where it's not picking up the input. Also sometimes the phone behaves erratically and can become completely unresponsive and flicks back and forth between home screens. Turning the screen off and then on again fixes it temporarily.

Display problem

Hi,
Factory reset - done!
Flash Android 2.3 - done!
I had the original Android 2.2 before, so the software is not the reason for my HTC Wildfire display problem.
Display image is moving up/down, the line of notification with signal, battery level..., is going in the middle, bottom of display and so on.... I have a screenshoot and a picture made with a very bad mobile camera, but hope to be enough!
I think few water drops inside 3.5 mm audio jack could be the reason, the warning LED(red one) is not working too.
Had someone the same issue? A way to fix this?

Someone else also had a similar issue. Here is the link.

but not sure if both cases are the same...
Cheers

...menu bar is floating from bottom to top, pushing all icons/options and it is nearly impossible to hit the right icon/option. Also when there is a keyboard, it moves up and down but it always reacts when pressed on position where it should normaly stand.
Thanks! So... I'm not the only one with this issue.
I think the reason for this screen it's because i dropped the phone before (3-4 days), but not noticed this right in that moment...
Anyway, I easy dropped the phone with intention several times recetly and the screen was OK for a day... don't know what can it be...
I'll try to find out how can be this problem fixed in a service and how much have to pay for all this...

After all, it seems my display don't want to turn on anymore.
I turned on my phone and it's working, it's able to receive calls with no problem, digitizer is working too because I can answer by tapping the known part of display where is that button!
I want to buy a new display and replace it. Could be anything else that make my display not turning on?

LeEco Le Pro 3-- red screen occur when pressing the power button to turn off.

Hello everyone, I got LeEco Le Pro 3 two weeks ago. For the past two weeks of testing, I notice that the screen quickly turns red when pressing the power button to turn the screen off. Is any of you facing this problem? It happens randomly, not every time. I have attached the video in slow motion capture in the 7z zip file. So you can see, what I am talking about. Let me know if any of you see it.

In mine sometimes it blink red. Power sleeping your phone rapidly. May red screen is reaction for force kill app?

I did not power sleep my phone rapidly. The red screen still persist. I don't know if force kill app cause it. I submit the feedback through the leeco experience center about this issue. This is what I got from them:
"Le Engineer
Hello,
I just get some information for this issue, in low battery level the red screen issue will happen sometimes. We also find the same thing on other brand device.
However R&D team are working on it. Hope it will be fixed in next generation product.
Sorry for inconvenience. Thank you for choosing the LeEco."
So I don't know if my phone is defective or not. It's hard to tell. Base on this message, look like there is no fix for this.

I saw this movie. My phone behave as same as your <sometimes>. May it's EUI problem? Somebody on other ROM like MIUI or CM13 can say something?

Mine occur sometime, too. Here is what I analyze:
1. On the home screen; when pressing power button to turn off, red screen occur sometime.
2. Any app that has white background like the waze app I use in the video, red screen occur every time I turn off the screen while leaving the app running. That goes for other app like chrome, whatsapp, google map, gmail, etc. Same result.
3. On the back button, when I press hold, the screen turns off. No red issue. This was on the home screen and this rarely happen. But for apps that is open, same issue.
That is what I like to know if it is hardware defect or software EUI problem. It looks like software issues. It would be great if someone would test it with different roms such as CM13 or MIUI.

It could be a software issue since I don't have that on CM.

I never seen with MIUI 8, can anyone give me a sequence to try ?
Tried some times, shut down it's too rapid to see with MIUI.

If you have another phone with slow motion support just like I did, you can try that.

Other thing I want to mention, I would like to know that if the red screen does not happen to people who have CM or MIUI on lepro 3, can any of you go back to EUI and try to do the same steps? If you can. This would more confirm that the software is the issue and not the hardware defect.

Any update?

Hi folks! I've been searching for this rare issue since I got my LM2 last week. I have the very same issue and I notice the same @crazy1990 mentioned here. Besides, I notice this red light is more noticeable when the brightness is higher.
IMO, I don't feel it's a matter of bad hardware (I hope so), as there are no clues of any other issues at all. I'm also using stock (23s) and I suspect it's some poorly designed fade for the ROM.
Any updates from anyone?

Yes. Red screen blink is noticeable when the brightness is high. As of June, I still have this issue since November on this stock rom 21s. So far, there was no screen degradation or any kind of lcd problem. Lcd works perfect since day one. A while back, I installed lineageOS and I still experience red screen when the rom froze and reboot. At this point, I still don't know if it is the software or hardware. I hope someone can help us out.

At least your report is positive. :fingers-crossed:
Did you try other custom ROMs? RR, Cuoco?

No, but I already tried omnirom and purity rom. No red screen issue. I also tried tars 21s and turbo base rom, the issue is there.

Great to know it doesn't happen on Omni/Purity. My biggest concern was an increasing degradation and/or flickering issues arising when changing to a stock ROM.
Thanks for your information.

Question Help with black crush issue, software or hardware thing?

Hi, i have black crush issue (it looks extremely pixelated on dark scenes), but it has a peculiarity. If i select "Vivid" on colour scheme, the display works fine. But as soon as i turn off the screen, and then turn on, the black crush appears again.
I tried every option in the colour scheme, in every one i have this issue, except on "Vivid" mode, which works fine until screen turns off, then appears again.
Is then a software thing? Will change the rom solve this issue? Or should i return the phone? Thanks.

Sorry mate but I believe this is a software issue. I haven't come across this issue with this phone, however, in the past, the black crush of my ROG Phone 3 was (partially) fixed by a custom kernel.
