Hey guys,
I replaced my broken lcd and touch screen with new one. Since then when I boot into recovery the touch is not recognized in the stock recovery and in the twrp recovery it takes about 15 seconds to respond to the touch.
This didn't happened before.
Is this a software or hardware problem?
Thank you.
most likely it`s hardware ,the compatible replacement may doesnt have the same flex configuration or its damaged.

It works fine after system boot up. But sometimes I have to keep touching the screen with one finger and use another to use the touch as usual.

Hi.
My screen just suddenly died, but I don't think it's a hardware problem, cause while starting it up I get vibration-response from it when touching the screen, but when PIN is asked the screen just don't work.
Any idea how I can fix this?
Thanks for any help!
No image at all + touch responses working = dead lcd display, but working digitizer. You will require a new screen module to replace it.

Hi and thanks for answer.
I get image and I get response on the touch until the PIN-code is asked, then the response goes away but the image is still there.
Any idea what might have gone wrong and how to fix it?

So you are saying the LCD is working, and the touchscreen is working?
Either your software is jammed or your touch-calibration is way off.
Either way, a hard-reset is the easiest way to resolve your problem.
There is no problem with the "visual screen", I see everything I used to see (so the LCD should be OK). It's just that it won't "recognize" or "answer" when I touch it, after a while.
I start it up, and everything seems OK. When "Windows Mobile 6.1" is shown the phone vibrates when I touch the screen. That means that it recognizes my touch, so the hardware should be OK. But when the PIN-code is asked, there is no feedback in vibration or anything when the screen is touched. The touch is just all dead, and the numbers I press won't come up or anything.
So, I think it's a software fail. I'm running one of Dutty's older ROMs, could that be a problem?
Can I flash it to another ROM with the "dead" touchscreen?
I tried to hard reset it now. Still the same problem, no response on touch.
The question : is it a hardware or a software problem.
Assuming it is a software problem - a hard reset would have solved it (since it worked before)
So the likely problem is the digitizer.
Yeah, it must be the digitizer. Is that something I can change / replace / fix myself, or do I need to send it to repair?
Thanks for help btw!
My G1's touchscreen stopped working recently. It didn't appear physically damaged but i tried replacing the digitizer anyway.
However even with the new digitizer, the touchscreen still does not work.
Also my message light, compass and accelerometer no longer function.
Any ideas? Would you reccomend replacing the flex cable?
flash some other rom cook to testing
i have trouble with touch screen with some rom
if the same trouble i think hardware have something wrong
ps: sorry for my english
Hello, I have a Motorola Defy, that I dropped a few times, so the LCD screen got damaged with blue dots on it, I made a mistake and thought that the problem was on the touch Screen, so I purchased a replacement, installed but, it was damaged, the touch did not respond correctly, I wasn't able to type correctly among other problems.
I got a refund, then ordered a LCD screen replacement, now that I have it here, I install it, and it's broken:crying: I know, bad luck and being a rookie while trying to fix my phone, ok, I put back my old (damaged) LCD screen to use it in the meantime, and the old touch screen, but now, the old touch screen that was supposed to being working fine, it doesn't, it has the same problem as the touch screen that I bought.
Question is: the problem with the touch screen, could be related to the damaged LCD screen? or the motherboard of the phone is damaged? the phone works great, the apps, the games, everything but the touch screen and the LCD screen, but, as I said, I went back to the default touch screen after using the damaged one that I received, and it works worse I don't know what's wrong, please help me out, sorry for the long post
Please post questions in the Q&A section. Moved there.
Put it in the freezer for 1-2 hours

Is this true?
true. fix some minor dead pixel if you put in freezer for one day. but your case... im dont hope much.
Try changing LCD + Capacitive Digitizer. (after trying the freezer trick ofcourse)
Well i will tell my story, which is related to your's as well,
i had a phone with resistive touch screen and it got screwed up, that is it does not respond correctly. So, i took it to the service center and they replaced the digitizer (touch screen) saying that previous one is broken. But, luckily the new one didn't responded to any touches they make.So, they replaced it again with the old one quoting that "your phone can't be repaired". So, i took it home with me.
Later i thought to calibrate the screen but the old one is not responding any more, no matter where i press
Later i calibrate it with the help of a software for windows mobile with the help of a PC. It took me to the calibration screen, from where i calibrated it, and voila, it worked... as good as a new one :victory:
long story short,
i think when you disconnected your digitizer, phones default values/drivers got messed up and are unable to find the new or the old digitizer you connect. I suggest you to go to the service center as these screens can not be calibrated.
Is there NO WAY at all to recalibrate the screen from the phone itself? or using an application? the delicalibration might be the problem....I'd like to fix it myself :/ thanks for the tip, never heard about it before!!

I replaced my original digitizer screen for the one I ordered it, it gave me problems, so I went back to the original one, which was working fine, and now it's not fully responding, that's why I'm assuming is something calibration related, thanks!
help
my search button back light is not glowing ..i saw it is also not glowing in recovery...any help
I dropped my phone and cracked the screen. So since I've did that, the touch screen doesn't work. I went to get the screened replaced and went to test it out and it still doesn't work. What's not allowing my touch screen to work after getting the screen replaced? If I change the screen does is the digitizer attached to the screen so therefore it will get changed too or is it a separate hardware?
Most likely faulty replacement part.
Try downgrade to 4.2.2

Hi, I've purchased a cheap diplay at ebay. Touch didnt work any more.. after a number of tests i found out this was due to a HW test at boot. When downgrading 4.2.2 everything works fine. Any upgrade 4.3+ failed to enable digitizer after reboot.
PS: When booting eg 4.4.4 with the old digitizer connected and then connect the new digitizer w/o rebboting the the touch was working well.. I'm very interested in geting a confirmation or reason what causes this issue kindly keep me posted
Most replacement screens use an original LCD (recycled from a cracked screen) fitted with a copy touchscreen. Either the incompatibility could be deliberate on LGs part but I think it's probably due to a driver update or something which has broken compatibility with the reverse engineered touchscreen. It could also be a coincidence, some copy parts are prone to just not working for no real reason sometimes.
Hey DrFredPhD
Can you imagine a costum rom with the old touchscreen drivers from 4.2.2 into 4.4.4?
What would this require: To compile a costum kernel? The drivers would usually be in compiled form in the boot.img, right?
I've tried to flash 4.4.4 with the old boot.img from 4.2.2. - but the phone didn't start (as expected..)
Can you imagine someone how could help me in this regard? I think there may be a number of people facing the same problem..
Anyway, thanks for your help - Greetings :good:
Binaries are available for nexus 4, maybe compiling from AOSP with older binaries would work, but you might break functionality too.
It's been done on other devices but probably not for the reason you want.
https://developers.google.com/android/nexus/drivers#makojdq39
So what are you essentially saying? Put the mb in a good working nexus and see if it works or that maybe the tech put a new digitizer with the old rom driver onto an older mb with a new rom driver? And that could possibly cause conflict with drivers or roms? Which in turn will not allow my screen to function?
The part he put on is crap, if you put a decent replacement screen on it'll work fine.

Are you sure? Because I don't wanna regret spending money on a new screen and it doesn't work. :laugh:
I've seen phones damaged by a repair bad enough that the touch will never work, but I've seen far more copy touchscreens that are useless.
Hi Guys
Just to say: may bad fake faulty touch "per se" works well under 4.2.2 and updated 4.4.4 also! It just prohibited "start" the phone with this digitizer attached! Both, phone and digitizer are fully functional and "compatible"..
Hi guys,
I destroyed screen recently in my i9505 so I needed to order a replacement. I bought a cheaper version of the screen with frame on aliexpress, took out the mainboard with all components from the broken phone, and it works (almost) fine. I have an issue with touch on bottom left of the screen. Touch is not correctly recognized there - when tapping, touches are recognized within 0.5 cm or so. When swiping though the region, instead of registering a continuous line, like on other parts of the screen, it is broken.
I'm suspecting hardware issue, but want to hear some opinions. Do you think flashing custom rom might work? I'm still using the original.
I'm attaching screenshots.

Is your screen completely destroyed, or has the glass broken only?
"I'm still using the original." - meaning original (stock) ROM?
it's Display problem. Hand over this display under warranty and buy another.
