S4 touch screen not working - Galaxy S 4 Q&A, Help & Troubleshooting

Hello XDA people,
The touch screen from a S4 from a friend of mine is not working. It suddenly stopt working and they tried to reboot it to see if that would help. But it didn't. The screen is not broken or anything like that. It suddenly stopt working.
I've got a S4 as well so i fitted the motherboard of my friends S4 in mine and the touch works. But when i've placed my motherboard in my friends S4 to see i've that worked but the touch screen didn't work with my motherboard in it.
Do you people of XDA maybe have a solution?
Greetings Kyrindia

Same problem here
I've got the exact same problem. Replaced LCD and digitizer but it is still not working. Additionally the screen is a little yellowish. Anyone knows if this might be related and any idea who to possibly fix this?
Hi, I have exactly the same problems, even tried with 2 fresh new digitizers. Could it be that they are extremely sensitive on the inside? Or is it some glitch somewhere?
Extremely frustrating!

Any help is appreciated so please guys help me now!

hi, probably problem with digitizer. i got similar problem some time ago, screen was working but the touch was not working at all or was receiving touch in different place then I was pressing. i send it to service (luckly it was still on warranty) and they change digitizer+lcd.
Unfortunately if screen isn't working at all it sounds like a digitizer issue
Did you change anything on your device recently just before you lost the screen?

Some help trying to fix a Motorola Defy?

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.

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!

my search button back light is not glowing ..i saw it is also not glowing in recovery...any help

[Q] Galaxy S4 i337 Touchscreen Issues

Hello,
Not sure if I can ask this as I am a brand new user. I hope you can help.
Friend brought me their Galaxy S4 i337 4.4.2 stock firmware. It acts as if the very top left (or around the area) is permanently pressed not allowing for any other touch function unless I touch that area "taking over" the ghost touch. The moment I let go, it is brought back to that area of the digitizer. Sometimes it works for half a second or 2 but goes right back to the problem area soon after. I have soft reset, hard reset with no avail. I have also connected a new LCD assembly which works perfect. I am assuming after this that the digitizer is the problem though I am interested what would cause such an issue to only part of the digitizer. She did mention she is prone for dropping the phone though it had been about 24 hours after the latest drop that the digitizer started acting up and has not let up since.
Any ideas ?
Thank you and again I apologize if I am not allowed to post this here.

Please help! My lcd doesn´t work but touchscreen does

Hi guys! Some weeks ago I dropped my phone and my whole screen cracked, so, I bought a new one and wanted to repair it myself to save some money, you know ^^.
But anyways I put everything back on, but my screen just won´t start. Well it is turning into a dark blue so I guess it actually works.... a bit. But everything else works just fine, if someone calls me I can easly just pick it up and talk, I just have to figure out where the Buttons are . It reacts to touch so I guess it´s only the digitizer... Please Help
Maybe some ports aren't connected well? Or the display was broken? Try contacting the seller
