Touchscreen dead strip!

I've noticed just today that there's a dead strip on the touch screen. It didn't do this yesterday. The Nexus 4 was dropped once from 2 feet high, but that was almost a month ago and everything worked fine until now.
The screen still looks beautiful, no dead pixels, no cracks, and the phone is in a protective case with a screen protector.
It seems to me that the digitiser crapped out, but I'm not sure why it happened so randomly.
A funny thing though is that when I drag something fast across the strip it works. And sometimes it'll recognise a touch as a long touch or two-fingered touch along the strip. Weird.
I attached a few touch test photos to show the issue.
Hopefully there's a fix. Has anyone else had this problem? And if you had to send it back to Google, was something like this covered under warranty? What should I do?

You can try to replace the screen yourself or tell LG/Google to send a replacement via RMA. They have parts floating around Ebay

How risky/costly is it to replace it myself? And does anyone know if it's covered under warranty? Cause if is, it'll be cheaper just to get a replacement from Google.
Are there other ways to check if it is indeed the digitiser? I've seen that sometimes touch screen problems are software related. And if that's the case, it'll be easy to fix.

And .... Out of curiosity, what does cause a digitiser to fail without the screen actually breaking?

Depends. If you follow the instruction properly, it works well. If you screw up, then Google/LG wont be able to help. A lot of people have done it and succeeded. There are great articles on the web. The price of a digitizer would be about $50-70. I MAY BE WRONG WITH THE PRICING.

In most cases no. Because it worked well and suddenly stopped working. Thus Google would say that its your fault. If you are somehow able to convince the Reps that it wasn't your fault, then there is some hope. I

One way is to remove it and put it to a tester or another motherboard and see if it works. But that takes a lot of time and money,

Anything. The phone might have overheaten to the point that it flashed a certain section of a digitizer. It may also be a battery problem that escalated. If you feel that it's software problem, flash a ROM a see if it works.
IMHO You should send it to LG and get it fixed for about $140~.

This problem should be covered under warranty. If you honestly haven't done anything to cause this damage. (I'm also clueless as to what a user could do themselves to make just one section of the digitizer stop working)
Then lasting 5 months or less would not be considered reasonable and you should be entitled to a replacement.
Remember it is down to the retailer to prove that you caused any damage.
And if you honestly did nothing and it just crapped out on you then you should have nothing to fear in sending it back for a warranty replacement

That happen to my iphone when it got water damage. But if you did not do anything wrong, it should be covered by warranty.

Ditto

I did an RMA explaining everything like I said above. I got my Nexus 4 replaced by Google, and they didn't charge me anything. New Nexus 4 works fine with no issues - I've been using it since May.

Same bug here in Italy where I'm living now even if the the phone was bought last year on UK Play store. Problem is Google rep wrote me RMA can take place only in UK or any other county where N4 was originally available on Play store i.e. NOT Italy.
Does anybody know of a workaround to get the RMA here?
Thanks

Yeah, I think the overheating might have been what happened to mine. I was using a blackberry charger and I think it might have overheated my battery and fried a strip of my digitizer.

Even i have got the same problem, i dont know who bumped this old thread, but please guide me to for a low cost workaround for my situation
No drop or glass break.. Dead pixel just one..

Hi,
Anybody found the reason for the issue, i too got the same issue; a dead strip exactly in the middle of the screen, My warranty is over already, so anyone has work around for this??

This looks like a dead thread, but Ill take a punt. I dusted my old Nexus 4 off the other day, which had exactly the same issue with the dead strip on the digitiser. I had tried replacing the screen and digitiser (I have up trying to get the original screen off the original digitiser). The issue remained, so I tried a full factory reset, but that also didn't work. I am now wondering if I should get a cheap motherboard, or try flashing the stock ROM again. Has anyone else had any luck with either?

Purple and black stains on the display

Hello!
I bought the Galaxy S4 about two months ago and since then, I always used it with a screen protector and a case. But today, I found that many purple and black spots and smears have formed on the AMOLED. I have never dropped the phone or exposed it to heat. I tried rebooting and activated the LCD test mode, but none of them helped. Is it a hardware issue?
Can anybody tell me what's going on and help me?
Best regards,

Definitely hardware. Looks like the AMOLED itself. If you have warranty, I suggest you use it, because that's hardware, not software.

Hm, thanks for the help, although that certainly isn't good news... I will try to contact Amazon, let's hope they can help me with this problem.

As there is a large concentration of purple in the corner, I'd suggest that Samsung will try and tell you its been dropped and in that case, I don't think they will cover it under warranty.
I wish you luck!

Thank you! Now the purple stains have spread all over the screen, making it very hard to read anything on the screen. This seems to be a very odd issue if you ask me...

Odd indeed ... usually when a screen is damaged or faulty bars appear pixel burned altered colors and stuff ... if i saw that and didn't know i d tell u that u definetely someone spilled ink on the screen ... those marks are exactly like it ... hopefully they ll repair it ...

I think samsung should change it under warranty because clearly, screen is not broken and still degraded. So it's bad display.
But they might say it's caused by water damage which is not covered under warranty.
Let's hope for the best.

They do have a way to tell if it's water damage, there is a sticker which turns blue when wet, so if there is no damage to the case, they should change it fine... I have had good luck with Amazon regarding returning faulty items...

Thank you guys for all the support, I sent it back to Amazon and today I got the mail that they have got the package. Now someone's going to look if this is covered by standard warranty... Let's hope for the best indeed!

Hope they change it for you. As for sure seems the amoled has burned

I am curious what happened? I woke up this morning and I had black and purple all over my screen to. It was fine when I went to bed. The last two apps I used were Pandora and Xtreme alarm clock if that matters

S4 Makes "burning" noise

Hi,
I recently repaired an S4 by replacing the screen/midframe. I noticed it makes a strange noise kind of like something is burning, on some occassions it does go to the samsung logo then boots back up, so it's like there's a short somewhere. it sounds like it's coming from the charging port but I can't think why.
Now, there's quite a few issues already with the phone. the sim card reader does not work, the volume up button does not work, the wifi and bluetooth does not work and the phone does have warranty until next year.
here's a video of the noise:
https://www.youtube.com/watch?v=9N-ppTj4...
is it possible I could replace this under warranty? I know I have replaced parts but Apple usually will replace the phone if there is still a fault on their end

Hello,
You repaired by yourself or through an authorized center?

I repaired the phone myself, it was only the LCD and mid frame which has been replaced. My friend has taken an iPhone 5s into Apple for warranty which had a full rehousing and LC D and they only rejected it because of a new battery. I have done the repair many times myself, it's possibly the easiest LCD replacement possible on a phone so I can't understand where this noise is coming from. Prior to this, the phone was absolutely destroyed, bent in half in some places and the glass of the LCD was actually peeling off, but the phone was still recognized by the PC and you can see no damage to the logic board

bump please somebody

It's probably the screen making the noise. You can try it by disconnecting the screen and then power on your phone.
Oh I read you have more issues. Is it water damaged or something?

any way to solve this problem？

The fact your screen goes on and off as you open and close apps
Would say something is really wrong.
Have you tried flashing your original firmware and starting from there?
got back to the original, Once booted update using the OTA
and see if you have the same problems

You would need to Download from the sammy site. But I know that's really slow.
You could use this tool,

Use Sammys official Smart Switch tool and do a device initialization form there. It will dl the latest firmware for you, wipe and reflash automatically
http://www.samsung.com/us/smart-switch/

find your firmware from your country here

Well, I think you display might die soon since i've got the same symptoms and the same messed up screen in the last picture and my display completely die after that but screen replacement fixed it.

Ive just fixed mine todayy! Same issue happend with me! It started yesterday suddenly! Mobile was getting very hot from from top "near the front camera and earpiece" even if i use the phone only for half a min or more, screen was flickering much, a green vertical lines came on the edge of the screen and stayed there, and the battery was dying very fast! I took it today to samsung service center, they have replaced the battery, screen, reciever and some rubber thingy i forgot what are they, now it is back to normal!

I think it would have been cheaper for Samsung to just replace your phone with a new one...

It happened to me also! But before the new update! The only thing I could do was to bring it to the technical support and I hope they will give me a new S7 Edge

Screen brightness not work after screen replacement

Hello
I replaced my Galaxy note 3 screen, everything is working good. But it seems I lost the brightness. It is on a high brightness and does not go down, even when I put auto. I need to lower the brightness, because of saving batteri and for a better reading to my eyes.
Do you have any solution? Is it a hardware or software issue?

Was the replacement an original Samsung? If not, many third party replacements don't support auto brightness.

No actually I didn't try a factory reset, should I do that?

I don't know how much battery power the app will use. When ever I had to replace a screen, I just looked for a phone with broken internal components and a working screen.
Try a factory reset but make sure you have a backup of your data.

Have you tried contacting the seller and asking for assistance?
I can't think of anything else to suggest.

Are you sure you not covered the light sensor. Maybee forgotten to remove the protection foil. The light sensor is beside the front camera. Is the front canera working?

Both the light sensor and front camera are working

Have the same issue with samsung s3, Everything works fine except the brightness won't budge, the light sensor is working fine. I checked with sensors multitool and it responds so there is no question of sensor being blocked or damaged.
I agree that with 3rd Party replacement Screen, Samsung just doesn't want to work, I would have gone for another device for the price I paid for the replacement display but I didn't thought of it at that time. anyways, Samsung sells crap, I have seen so many users having issues with their displays, even the newer ones. I have stopped investing in Samsung anymore, lost trust, feels like been betrayed with the one that I fell in love.

Auto brightness often doesn't work with any 3rd party screens on any phone.
