In this case, replacement of the screen is completely unprofitable.
Resurrecting this thread, I too am having the same issue. I do not know how some of you are making those maps of where in the screen is active, but I know the 1st 5th column of the screen just ignores me. How hard is it to replace the screen assembly (glass, digitizer, lcd)?
hey, so am i understanding right that you charged your phone with your laptop and it corrected itself? i have an lg g2 and i have this same problem. it wouldnt be as big of an issue if it didnt break my knock on.
I have a Nexus 4 for about 2 months. I have this problem since I got it (not new) with a section on the right side, from the top to bottom. Last night was the first time I fully charged my phone through USB port on my laptop, let it untouched all night. Today I was super-excited to notice that my screen proplem disappeared. Well, after 9-10 hours, it reappeared. I'm charging it in the same way right now and I can hardly wait tomorrow to see if it happens again. Someone on another forum affirmed that his phone completely repaired doing this. I'll come back with an update.
Update: I confirm this really Works. After another night while charging through USB, my phone had the problem in the morning and I decided to draw to share my section. Just 1 minute later after saving the screenshot it started working perfectly. I have two screenshots now, one with problem, one without it. I tried to post them, but I'm new here and I'm not able to upload things.
(I hope my English is good enough for you to understand)
I tried the USB charging ,but today morning the screen ia not fixed yet, I am using Samsung cable , did you charge it to 100% overnight or what???, mine was charged only to 70% as slept for very few hours...
My Nexus 4 suffered extensive water damage 4 days back due to heavy rainfall and died. Replacing the power IC at a local technician's shop helped and now it's working fine except for the section of top 2 rows of the QWERTY keypad that are unresponsive. Like other members who've mentioned this, I'm unable to accept or deny notification prompts, or type messages. Even on auto-rotate, my screen is not rotating to landscape mode. There is still a bit of water left on the screen and I'm praying that once it dries up, the screen will become better. However, there is one method that has helped me use my phone a little over the past 2 days.
Under the Accessibility section, turn the text size to large. And then turn on "Magnification gestures".
If you are unable to tap the notification prompts, magnifying the screen will allow you to push the notification bubble to a more responsive part of the screen and make them go away. You could also turn on Google Voice typing to respond to Whatsapp/BBM/SMS texts. It's not a permanent fix but at least you can use your phone a little more.
I'm afraid the only permanent solution to this problem is replacing the entire display that will set you back by at least 5k Rupees (approx. $90) here in India.
