[Q] lcd problem lg optimus 3d

Lost touchscreen handling in upper and lower part of my screen!!!Pls Help!
I have a rooted device with xsba's custom rom (4.0.4). The problem started before this ROM. I am pretty sure that this is no rom issue. I have flashed the phone several times with numerus roms. Problem persists.
I already have changed touchscreen once because of a serius fall (broke) approximately 6 months ago.
These are all the facts. Before xsba's rom i used thiaiz o3d. (2.3.7). The problem started one day that i hadn't charged the phone up. When the battery fell under 5 % the phone went berserk. (Numerus button presses all the time)
I couldn't even reboot. When I finally turned it off by removing battery and restarted the phone the upper field of touchscreen of the phone never worked again.
Yesterday i failed to charge again.ASfter finally restarting the same issue appeared in the lower field of touchscreen. Please advice!!!!!!!!
Is there a way to solve this problem without changing the touchscreen?

Now , you need to go to developer options in the settings and enable show touches option. Then you touch and slide to the parts that don't work . If you see the line going there , then it's a problem with your ROM. If it's not , then you possibly have a broken touchscreen. Check the contact of the touchscreen ribbon and see if it's tightly sitting on the slot , press it down and try again.
If it's not working , you have no choice but to replace the touchscreen. You can buy one off eBay for 19 dollars and free shipping. It's made in China but it works well without problems for the past 6 months with my device.
Hope I helped.
Cheers!

I am going to buy one for me from ebay today. I have no choise as it appears.
I feel the need to thank you for your time and for the solutions that you provided me with.!
You have been most helpful.

HI did you ever solve this? I have the same problem, or very similar with middle and lower sections of screen dead, strange ghost touches and screen going crazy every so often, all started after I rooted phone. Was it just a broken touch screen? Cheers

Touch Screen Issue

Hello everyone,
i'm experiencing a problem with my shield tablet since couple days ago. My touch screen is not working. Up until yesterday i had to reboot in order to make it to work but now even when I'm rebooting is not working.
I tried to reset to factory setting but it's still the same. I'm curently running lollipop. Does anyone has a solution?
Thanks in advance for your replys guys.!

Does the screen work when you restart it in bootloader mode?

hopefully you get a good answer mine is starting to lose multitouch at times.

Then your device is sadly broken.
Just RMA it to Nvidia, they will replace it swiftly.

I've just got this issue today. Using my tablet normally and suddenly the screen touches aren't executed or responsive. I haven't updated to lollipop still using Kitkat 4.4.2

I am on my second shield tab and multi-touch is a problem. For example, in a game with analog joystick on left side of screen and pressing the action buttons on the right side to not both work at the same time. Happens on multiple games. Is this a known issue and is there a way to calibrate or correct it? Thanks.
EDIT: i just did a touch screen calibrate and that fixed it. good to go for now

Screen non-responsive when using Smart Display - Hardware or Software Issue?

Hi
Just got my U12+ today. I've noticed that quite often if I unlock the phone by fingerprint, it shows the home screen but the screen is totally unresponsive. I can't click/touch anything.
It remains unresponsive, even if the screen times out (1min later) and then I reunlock.
The only way to fix it is to use the power button to switch off the screen and then it will work immediately afterwards when I unlock.
I have done multiple restarts, and 1 hard reset and it is still happening.
Any thoughts on what is causing/how to fix?
UPDATE:
I've spent quite a few hours googling and testing different setting options, and the issue seems to only occur when "Smart Display" is turned on.
If the Smart Display is on (either motion or always on) gets engaged, if I then unlock via Fingerprint, it shows the home screen, but the touch screen is totally unresponsive. It doesn't register any taps/touches (I turned on Dev options).
Is this a hardware or software issue? Anyone else experience this?
Thanks

Phone model and current software build.
Are you rooted? Any root based mods, kernel, room, etc.

Hi
Thanks
U12+ running 1.21.454.3
Totally stock. Only got the phone on Saturday.
Did one hard reset and issue still there.
In usage since my last update, it is 100% related to the Smart Display. Absolutely no issues when it is turned off. When I enable Smart Display, then it starts freezing again on unlock.

Hi,
I'm having the same problem too..
I got my set on the 15/09/18, Hong Kong Set.
Mine is currently on 1.25.708.3. But prior to the update, I am already having the same problem described by leginag.
I even tried to do a factory reset but the problem still surface. It will become unresponsive after waking up after a period of screen off (not sure how many minutes).
After turning off Smart Display ( thanks leginag!) , I'm able to use it flawlessly. I was about to unlock the bootloader and flash a custom rom though..
I think this problem is quite disruptive, especially when a call comes in, or when launching the camera app through the edge sense. I can only snap using the squeeze.
Nonetheless, I hope there are other alternatives to Smart Display though..

Hi, I've been having the same issue. Thanks for looking into it hopefully it gets fixed in the next update.

I hope it does get fixed. I reported it to HTC and they said they would forward it to their engineers. That was 2+ weeks ago, and nothing else heard back.
Best thing for you to do may be to submit a support ticket to HTC. If everyone who has the issues sends it in, this will flag it with their engineers that it is a wider problem.
Could you let us know your model/firmware?

I have contacted HTC and am awaiting a reply. My current software version is 1.25.708.3

Thanks.
Hoping this issue is software related. So far, only people with Asia models have reported it (only 3, but at least I'm not going crazy by myself!)
ASIA HK - x2
ASIA JP - x1

Got a response from HTC, saying it is a software issue and should be fixed in next update - around mid-October.
Today, I got information about that this issue will be solve by software update.
Moreover, it is arranged on around middle of October.

Thank you for this. I just got my u12+ and thought it was faulty.
Turned off smart display.

I'm having this problem as well, Asia HK.
Curious, is anyone also having problems with TWRP? I almost always get a nonresponsive screen when fastboot booting.

Just a heads up that the 1.30 update has fixed the issue for me.
Which is a relief. Not that I was missing using Smart Display, but just feel better not having an issues with my phone

Hi there,
I am using Asia HK and have the same problem with you.
But I still didnt receive any update patch for 1.30. May I ask which area did your phone belong to?

Asia TW and Asia JP have already received the 1.30 update (I had to manually check for it though). Hopefully HK will be soon!

I've had this issue twice, once on 1.25 and once on 1.30 so I do not think it is fixed yet but it has been very rare for me. Only twice since the phone launched but it is very inconvenient when it happens. I could only fix mine with a reboot.

Removing my original reply as I don't believe it relates to this bug after all!
(A Factory Reset sorted out my device, incidentally)

We've heard of similar cases here on XDA before, sounds like a dodgy digitizer to me.
Had the same problem last year, after that I started getting these so-called snowstorms and my phone kept rebooting itself.
I ended up purchasing a new screen on eBay and was lucky enough to get a genuine one for about 70 Euros.
All went well for me, new screen's working flawlessly.
If the problem persists or even gets worse you should perhaps think about whether it's worth the money.
Removing the old display and assembling the new one isn't that difficult, there's quite a few YouTube videos out there.
If you have any further questions feel free to ask.
Edit: When did you start having that problem? I don't think it's probable but maybe it's got something to do with the ROM you've got installed. Try flashing another one (e.g. AEX Pie, LOS 15.1 or stock) without any custom kernels or boot into TWRP to see if you've still got the same issue. Play around a bit to see if the problem still persists. Remember to back up your important data. Again, this probably isn't the cause but it's still worth trying before considering to buy a new screen or phone.

No problem. Here's the link: https://ebay.to/2N7SQYO
Hope it's OK to post this on XDA.

I've suffered this issue since 1 year and last month the phone couldn't display itself anymore, my trick was to slightly twist the phone using both hands and it will temporarily enable the display, got tired of it and I went to a local mall offering mobile phone repair services, told them the issue, most of the shops refused or would just advise me to get a new screen buty persistence in telling that the screen is fine it might be just a small misalignment or loose contact and thankfully one technician listened to me and just asked if I'm willing to risk the screen being damaged and we'll what do you know he just re seated it and walla phone is alive again in fact I am typing this through my S5

Sudden touch latency issues in OnePlus 7 Pro

I received my device back yesterday afer a screen replacement that took 15 days (the screen glass had broken but touch was working fine.)
I received the latest OOS update when I booted my device. After updating, my device has extreme latency issues wherein scrolling is causing taps, gestures work infrequently, and even fast typing is difficult.
Is this a software or a hardware issue? Anyway I can check?

From the looks of it, it's a hardware issue...The screen they replaced has some issue...it's best to speak to them and get it fixed again...

Received my device back. They hadn't calibrated the display after replacing it, which caused the issue.
