[Nexus 4 Q&A, Help & Troubleshooting] veketash:
It seems this annoying thing changed on my device for few days. I had some times when it functionned without the screen problem and times when it didn't work for weeks.

For about a week it doesn't work a lot of time, but sometimes my touchscreen simply freezes and I have to lock the screen and unlock it again. After doing that, my screen works without that bottom-to-top line being unresponsive. If I stop using the phone for a night, for example, I find it the same way in the morning, but if I use it, it freezes again, but after I do the lock-unlock thing, it doesn't perceive touches on my 1/4 inch bottom-to-top line. I'm starting to think this is a software problem. I have the 4.4.2 version of Android on Nexus 4.

I'm so nervous about it.

Did anyone find a solution to this?
[Nexus 4 Q&A, Help & Troubleshooting] Mae7:
I've started to get this problem. It's at the top section of the screen and its keeping me from using some apps correctly :eek:

I always looked after my phone and I've never dropped it onto a hard surface. The screens in perfect condition. I've also tried different ROMs but nothing seems to fix it.

I'm gonna try that USB to PC method and see how it goes.

Can you give me an update on this? I'm facing the same problem and USB charging didn't fix it. I've charged it through USB twice. Does it take longer for the changes to take effect?
[Nexus 4 Q&A, Help & Troubleshooting] ImperatorShade:
Same problem here.

I have a nexus 4 i bought from the USA, but I live in india. Everything was working fine until a few hours ago when I was playing ski safari and my phone's screen froze! So i locked it and unlocked it and it was fine! Then I came back home and the middle horizontal portion of the screen doesnt work, making sending messages impossible! Im trying to flash a different rom and kernel hoping it might fix it! Glad to hear many others have the same problem.

EDIT : The problem started happening when my phone was almost out of charge, in the 1-10 region. Now Im charging it, its at 11 % and the dead screen is slowly disappearing.

Is your phone good now?

I too have started charging my phone via usb from now. How long it took you to solve it?
[Nexus 4 Q&A, Help & Troubleshooting] rmenes:
I believe it is a hardware issue on mine. But it is strange that only the most critical part of the touchscreen has a problem (the bottom part with the soft buttons), and it is weird that so many people have this problem.

But anyway I found a temporary solution, but you need root to your phone.

1 - Install Xposed Installer

2 - From Xposed Installer install Gravity Box

3 - Inside Gravity Box choose Navigation bar tweaks

4 - Go to dimensions -> Navigation bar height, and increase the height to 115%.

Now the buttons started to work. What was done is to increase the area of the buttons to a part of the touchscreen that is working. I didn't fix the root problem, but the buttons are working fine now.
[Nexus 4 Q&A, Help & Troubleshooting] StarInSky:
Solution found!

Had the same issue with an irresponsive section, and finallymanaged to fix it! Now it works perfectly!!! Just remove the rear lid, and replug the sensor screen connerctor! Take it out and plug back in, than put the lid back, and enjoy using fully functional sensor display! Tell if it worked for you!
[Nexus 4 Q&A, Help & Troubleshooting] CaptainKitten:
So I just started having this exact same touch screen issue. I'd like to try this method to fix. Any chance you could link me to some additional info on getting to the sensor screen connector? I haven't ever disassembled my nexus 4.
[Nexus 4 Q&A, Help & Troubleshooting] CaptainKitten:
Alright, so I just went through some tutorials and disassembled the phone, unplugged the screen connection and plugged back in. Unfortunately, after I did this and booted the phone the touch screen still had the unresponsive strip in the middle.

Not sure at this point.
[Nexus 4 Q&A, Help & Troubleshooting] StarInSky:
The lid is removed easily, just use your nail or something thin. Then find sensor screen cable. It always goes from the side of the tablet, like on the picture right under his thumb and has two connectors: http://twimgs.com/informationweek/b...xus-Tablet-Teardown/Nexus-teardown-2.huge.jpg . Don't forget to loose a white handler on the connector, and then take it out slowly, and put back in till the end. That's pretty much it. You can probably use any screen replacement tutorial if you still have any issues.

I'm almost certain, that each metal thing on the connector send the signal from some stripe of the screen. Try it again, but push it harder and further, so it will have full contact. I'm not sure, if this is the widespread solution, but it helped me in the same situation. I also did a hard reset before doing that, but it didn't help. Maybe it works in combination of some sort, you can try it, if you don't need your data.

Mine is exactly same.

center horizontal belt has not responsive. Do you find any solution? mine is ran out of warranty.
[Nexus 4 Q&A, Help & Troubleshooting] CaptainKitten:
I've tried disassembling the phone and replugging in the digitizer. That does not seem to help at all in my case unfortunately.

The strangest part that I've noticed is that if I leave my phone off for a long period of time (ie. overnight) when it first starts the touch screen works perfectly. I can use it for some time without any issue. But eventually, after a bit of use, the exact same non-responsive strip of the touchscreen comes back.

Because of it working after a long idle period, I think it's pretty likely to be a heat related issue. Which makes sense given that the first time I saw this issue a couple days ago was after I spent a while playing epic angry birds. That tends to make my phone run pretty hot.

Today since I woke up I've made a point to not run anything very long that makes the phone heat up. So far... my touchscreen is working without issues.

[Nexus 4 Q&A, Help & Troubleshooting] veketash:
still works

Hi,

I bought my phone with that problem and after seeing this method on the internet, I tried it. I left my phone charging through USB one night and the next morning the problem was gone, but reappeared the same day. For 2-3 months it had days when that section of the screen worked and days when it didn't. Now, for about 4 months, I hadn't any problem. The hole screen works and no ghost touches, From that first night I've been charging it only with USB on my laptop, but occasionally when I need that I charge it using the wall charger, but still NO PROBLEMS. Hope yours will recover too. Have a nice day!

PS: it doesn't matter how much I charge it. I charge it how I need it.

Water damaged Nexus 4 screen workaround

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.
[Nexus 4 Q&A, Help & Troubleshooting] krish1985d:
I am also in the same boat. why is this common problem not being addressed by google?

Is this really a hardware issue. and replacing the display is the only way to overcome this issue?

how does this happen simply without any damage made to the screen or phone.

I think managing with magnification and large text size is better than spending 5k Rupees.
[Nexus 4 Q&A, Help & Troubleshooting] Utkarsh-ezzo:
Thank you man, that gave me kind of hope. I will keep charging it from USB, I only have Samsung's data cable so I have use that only, and some times I put it on USB 3.0, I will wait and hope that one day it will be totally fixed..

Screen replacement

I'd been facing the same issue last whole week after my phone suffered extensive water damage. Sadly, the only permanent fix for this is replacing the entire screen. I got mine fixed yesterday and its been working perfectly since then.

---------- Post added at 11:12 AM ---------- Previous post was at 10:57 AM ----------

Certain hardware parts can't be tweaked with but have to be replaced completely. In the case of water damage to the screen, replacing the screen helps the issue not return again. However, if you are looking for a cheaper way out, you can try changing just the digitizer rather than changing the entire lcd. I'm not sure if any Indian sites sell only digitizers. Neither am I sure about how many technicians will agree to going thru the process since it's almost 1/4th the cost of replacing the screen and is as tedious as changing the screen. You can google up digitizer replacement and see what it actually involves.

My Nexus 4's screen had no scratches whatsoever and still I had to resort to shelling out 5k and get the thing replaced. Best of luck buddy. :good:

May I know which rom and kernel you are using??

Because I have been charging my phone thru usb only since past 3 days but that part is isnt working at all, previously when I tried your method it was working but not now
[Nexus 4 Q&A, Help & Troubleshooting] veketash:
Hi,

My Nexus 4 is just stock, I never flashed or rooted it. Stock ROM, stock kernel I suppose, with KTU84P build version. Many people say that chargers could be faulty. I guess that was the problem for me too, even though I use it sometimes when I'm not able to use a laptop.

Have a nice day.

I was about to buy a officially refurbished N4, and after saw this problem, I don't think it a good idea.

Any away, do you guys know if it is really OFFICIALLY refurbished? (I live in Singapore)
[Nexus 4 Q&A, Help & Troubleshooting] CakeSpork:
Hey guys,

I just wanted to share my bizarre experience with this problem. I left my phone lying screen facing down on a table where water had spilled without me noticing. After 30 minutes I picked up my phone noticing it was wet, I immediately turned it off and left it in a bit of rice overnight. I was relieved to find it working the next morning, but throughout the day I sadly noticed a horizontal band of pixels not responding to touch anymore, about 1cm wide.

I bought a new LCD+Digitizer assembly and put it on my Nexus 4 fully expecting the problem to be resolved, but it was not. It was a problem on exactly the same band of pixels. I disassembled the phone, cleaned everything, left the motherboard soaked in alcohol overnight and tried the USB cable tricks, rebooting to factory, and using adb to do whatever I could, but to no avail. I've written off my Nexus 4 and was eagerly looking forward to the 6, but it has disappointed me tremendously. I now have an LG G2.

So, a word of caution: replacing the screen may not fix your issue. As bizarre as that sounds.
[Nexus 4 Q&A, Help & Troubleshooting] yakky:
I just bought a refurbished one from expansys and it the middle of the screen is unresponsive. See screenshot.

I called LG and was told they don't warranty ANY refurbished items... good to know, I'll never buy anything refurb from them again.

Expansys was great, just a few questions and they are cross shipping one to me.
[Nexus 4 Q&A, Help & Troubleshooting] Serris:
Come to think of it, I had the same issue, navbar part of the screen was unresponsive.

I sen't the device to LG and they replaced the whole screen plus the motherboard (device was under warranty).

So maybe there is something with the motherboard aswell the screen.
[Nexus 4 Q&A, Help & Troubleshooting] hp420:
I dropped mine two weeks ago and the exact same thing happened. starting immediately under the status bar, extending the whole width (in portrait mode) and about 1cm down, it doesn't respond at all. The same section is unresponsive if I rotate to landscape, too. The worst part is it's in the EXACT spot Google has started adding buttons, like the headers and 3-dot menu, into the API, so now about 5-8 of my apps have absolutely no way of accessing the settings. I was looking at screen assemblies, but they cost almost as much as a used N4 does on swappa, so I think it's finally time to get a new phone. Unfortunately, this couldn't have come at a worse time, since work is painfully slow for me right now.
[Nexus 4 Q&A, Help & Troubleshooting] leetom:
Good for expansys.

I finally bought one too, and luckily it hasn't had any problem for now.:)
[Nexus 4 Q&A, Help & Troubleshooting] TwistyValhalla:
Sadly, I'm on this thread because I now have the same issue many others here have reported. Top part of the screen (about .5 inch in portrait mode) suddenly stopped registering touches yesterday. No drops.. no nothing.. just stopped working. Screen looks to be in perfect condition from the outside. Probably something messed up the digitizer. One weird thing that happened earlier yesterday was that I found the phone turned off with 80% battery left. Not sure what caused it.

I've read through the thread and I'll try the USB charging method first. If that doesn't work, a hard reset and then I'll open up the phone to check the connections. Thankfully the N4 is not my daily driver now.

Got my N4 from the Canada Play Store the day it came out (early Nov, 2012 I think). Remember getting up early in the morning to get the phone. Was one of the lucky ones to get it because the store was only up for a few minutes. So ya.. out of warranty. It's sad that the phone stopped working like this out of the blue (I take good care of my devices) but I guess a 2 year life is not that bad in smartphone terms.
[Nexus 4 Q&A, Help & Troubleshooting] reallyroy:
The exact same thing has happened to my LG Nexus 4. A band exactly in the middle has completely stopped responding to touch. I'm now unable to power off my phone or dial the number 1, 2 or 3. I just keep tapping and once in a while it responds.

I will try the USB charging method, followed by the connector method. But if that doesn't work I'm thinking of buying and replacing the entire screen. I've seen some fix it videos on the net. I saw a mention here that even that didn't work though. Can you provide any further inputs?
[Nexus 4 Q&A, Help & Troubleshooting] veketash:
I suppose you've read my comment about USB charging. I had exactly this problem for a long time before I decided to charge only with USB connected to laptop. It worked the very first time, after I let it fully charge one night plugged on laptop and the next morning the problem was gone. But then reappeared occasionally. This means it won't work so fast, I guess it needs some time though (days, maybe weeks) until it's gone completely. Almost a year passed since I never had any screen problem :) Sometimes, when I don't have a laptop to charge, I charge it normally, but the problem still doesn't appear.

I hope it will work for you too.

Just to share, here's a screenshot of the section that is unresponsive -- on-touch of this section triggers areas above and below it instead. -.- Unresolved after a number of hard resets; so here goes with the USB charging as an alternative solution. Hope this works for me.

I have the same problem just that the section of inactive touchscreen is like an L with the up down. I tried to charge it from the laptop but is not working at all. If I change the digitizer and the screen would work ok after that? But what if I change only the digitizer? I read on a thread that a guy changed the digitizer and the lcd and nothing changed. Would be a battery failure ? What can I do ?

I was facing exactly the same issue, I replaced the Google ROM with CM 12.1 Custom ROM and surprisingly , after a year my screen issue is fixed. Google is creating problems for old phones , so users stop using and buy a new one. Really hate google for this. Lot of nexus 4 users replaced with new screen for this issue.

I've got this problem as well and my phone seems to switch between having no input from the problem area or glitching between lots of random input. I can work around the first behaviour with the Gravity Xposed module, increasing the navigation bar height (my failure area is right at the bottom of the screen).

Does anyone know a workaround for the glitching input? Being able to completely ignore input from that part of the screen would fix this, is there a way?

Still facing middle screen issue

I realized after 2 days when screen issue reappears. It worked for 2 days without issues when I flashed rom, I thought that fixed the issue.,apparently not. I was not using cellular when it worked for a day may be that didn't heat the digitizer and it worked. Second day when I used with cellular, it worked for some time and started acting again. I again switched off the cellular network and let it cool again..now sometimes it works. Not sure if it's a hardware issue or updating the rom caused this issue previously but it started only after getting the update from Google to KitKat.

[Nexus 4 Q&A, Help & Troubleshooting] escombralls:
My nexus 4 fell down yesterday, from 1,5 m back down, without the Ringke Fusion cover (I was just trying to put it after cleaning the phone).

Now, the back glass is cracked (I don't mind about it, it's not a big problem using the Ringke Fusion) and, sadly, I have now a dead zone on the upper line of qwer keyboard.

I'm really happy with that phone, and I would like to repair it.

2 questions:

1. I suppose that the drop has broken somehow the digitizer, but: do you know if a cracked back glass could be also causing that dead zone in the screen?

2. Supposing the origin is the drop itself, do you consider replacing only the digitizer or all the screen (the screen itself has no scratches).

Thanks a lot!
