Is your phone in warranty?

can you give us some basic information? such like rom & kernel version, wether you rooted and ade using cputuningtools or something like that.
if you are under stock rom(original samsung & all further updates over kies) and u have done nothing unnormally so far i would recommend use the warranty too; )

thanks guys
i have not rooted or changed the stock rom
i only factory reset it when the problem started
i just discovered that when i plug in the charger the touch screen works normally but does not respond to touch when not charging

I had the same issue. I got my touch panel replaced by the Samsung guys. That's why I was asking whether your phone is under warranty or not.

Here we go, this proves this has nothing to with CM9, this guy is on stock.
Many people are blaming CM9 for this and claiming it caused the problem.
It's a hardware defect.

Agree. :good:
I'll wait for a few weeks or till the phone is usable for the kernel 3.0. :fingers-crossed:
If not then no other option but create a Rs.5000 hole in my pocket. :crying:

Same case with me... Bought the i9003 March 2011.
I'm on DDKP3 and around the same time as the OP, my touchscreen started to act strange... responsive only when charger is plugged in. Tried factory reset, but problem came back after some hours!
If this is a product-wide issue, then I guess sammy should replace it for free, even if it's out of warranty... too busy to go to the nearest service cenrter, will check later.
Till then, please keep me updated how it goes for you.
---------- Post added at 02:31 PM ---------- Previous post was at 02:24 PM ----------
Just wondering, if a reflash of DDKP3 via ODIN or any custom ROM would solve the issue... please suggest.

I guess the sensitivity settings (or something like that) has changed without you knowing. Don't know if it is the same as s2 but in s2, sensitivity of the phone not plugged in the charger and plugged in has different settings. So maybe the settings for it in your case (unplugged) has changed but not on the plugged in settings. It's all in the kernel btw.

Maybe asking a kernel dev if the values changed or what not. If i'm correct then it's a software problem, if not then maybe a hardware problem.

Same problem!!!
It happened last week when my phone surprisingly started showing this problem. After unlocking the phone the screen becomes unresponsive. In my case it is just 1-2 secs after unlocking the phone.
It lasted for a day, I tried flashing different ROMs. I was on XXKPE when it happened. And than suddenly my phone started working fine until yesterday when this thing again happened and the problem still persists (I am still on KPE). I dont know what to do.
I think it can be some software problem as the screen and touch keys do work for some time before becoming unresponsive and even the logcat shows no problems for the touch screen. I am going to try more ROMs now. Will keep you posted.

Possible solution !!!
Friends, I think I found a possible solution for this issue. Though it seems to work for me... I have to keep the phone under observation for some days until I can say it's the final solution.
A similar thread: http://forum.xda-developers.com/showthread.php?t=1695149
The possible cause for the touch screen going unresponsive seems not to be a hardware/software glitch; but environmental issue! And it doesn't depend on the ROM your'e running.
I noticed that most people from India having this issue say that this problem started in June, when the rainy season starts and it gets humid and damp.
In fact my phone showed this issue when it had rained for the last 2 days and it was very damp and humid inside the house.
You can do the following:
1. Take out the back cover, memory card, SIM and battery.
2. Place the backside of the phone near a hot air source (on top of a running CRT TV/monitor, hairdryer, laptop fan vent) for sometime.
3. Reassemble and check if the problem has gone away.
Do not panic if the handset gets a bit hot in the process!
In my case, I left it on the top grille of a CRT TV for a day which ran for 8hrs.
Do let me know if this works for you...

Flashing the ROM does not solve the problem

Thanks to agnivo007.
I guess the climate is the only reason. I used his method to heat up my phone a little bit by charging it enough. Than it started working fine. No problems since then. Lets see.

But changing the panel solves the issue..
The kernel won't reset itself if you change the screen.

Touch Screen non-responsive Problem
I had the same issue and when i dismantlement the thing, came across a small batter. could this be the reason? Cos while charging this battery is not used but when running with battery, this small dry typed batter can be in use.

Found Any Solution
Could any 1 find a solution for this matter?
If so pls. update. Mine is still there.
I can't get rid of it.

Nexus 5 screen died today + dangerously hot lower screen

Went to unlock my phone this morning off the charger and the screen is totally dead. Couldn't unlock or do anything to it or even see what was going on, called Google and ordered a replacement ASAP.
Went through the not fun task of doing a nandroid backup without seeing what was on the screen and doing some trickery with screenshots then backing up my entire SD card.
However, here's the strange and potentially dangerous thing that I noticed later when I got home this evening. I went to look at the phone and go to a fastboot flash with the factory images and went to touch the bottom of the screen. When I went to do so, to the little bit of the left of the LED light was a SUPER hot portion of the phone. I almost burnt my finger it was so hot.
Not sure what to do about the issue, I feel like if I just call the support line they won't actually take in my concern legitimately. Any suggestions?

thats something quite strange
let us know what google says about RMA and this issue

Agree, maybe it's just your phone, maybe it's all the batch. Which batch/model do you have?

On my Transformer Infinity, sometimes the screen won't turn on at all. On a few occasions, if I press Power enough times, I get a glimpse of a message saying the Launcher process has stopped, but then my touchscreen doesn't register any input. The tablet is also sometimes running quite hot at those times. The only way I know to recover from this is press the Power button long enough to force a reboot, then everything is normal. Could this be what's happening? Do you know if the phone is still running under the black screen? Have you tried forcing a reboot, and did it work?
As for the hot phone, I've noticed my N5 does get a bit warm when I'm using it intensively (4G, WiFi, Bluetooth, GPS and screen on all at the same time and in use) but not enough to burn me. Could be hard to tell which component is heating up like that since I think it could be the screen backlight, SoC or battery... Do let us know if you find out more.

I had called them and reported the screen totally dead with lines streaking vertically and got a new replacement ordered. It wasn't until late last night when I got back and had the screen on in this dead mode that the bottom was extremely hot. I'll have to call them back and let them know

Yeah, no its definitely dead. There were streaked lines across it, rebooted it multiple times. I ended up going into the bootloader and recovery via adb/fastboot and all that jazz. It eventually just would not work now.
In regards to the hot part I definitely think it was the lower part of the screen. It was quite literally half an inch away from the LED to the left. Was super super hot then once I shut the defective screen off (I could tell by the backlit light or whatever) it wasn't hot anymore after a minute or so.

Is it black/white? 16 or 32? When did you get it?

32gb black version. I ordered it immediately when they announced it that day.

mine gets really warm when i'm doing a TWRP backup then it goes into bootloop after and wont cool down. i have to force it to power off from recovery and let it cool, but i've always seen it happen. i wonder if yours was attempting to boot over and over for hours and cooked itself.....? i have a launch day black 32gb too, running Cataclysm with Franco at the moment but it was doing it on rooted stock with stock kernel

I had to send my 19 day old 32Gb Red Nexus 5 in to LG for the same reason. I was using the phone and all of the sudden had vertical lines and the bottom of the screen got burn your fingers hot. Waiting to see what LG does with my phone. The only thin I can figure is the synaptics chip which controls the screen is bad. Its the only thing in that area that could get that hot. I also noticed when I first got my phone the glass in the same area looked like it had a slight wave in it. Didn't think anything of it at the time. I'll let you know how it goes.

Is RMA/replacement applicable for Rooted and unlocked devices?

I don't believe its an issue with developer phones as long as the issue wasn't caused by something you did like brick it by flashing a wrong radio or something like that. It has to be a manufacture defect to get it fixed for free.

My device issue is related to power button. there is no software issue.
The power button is rattling since from the purchase of the device.
Hope my device gets repaired.

Like I said. Hardware issues that are production faults should be covered.

[Q] [HELP] Phone suddenly freeze and show weird screen

Hi, I have been looking all over the internet and search the xda thread but I couldn't find anything related to my problem.
So this morning when I wake up, I turned on my phone and after I used it for awhile suddenly my phone stopped working (freeze/hang) and started to reboot itself. After it reboots my phone's screen as per attached below.
The problem lasted for a day and started to driving me nuts!
Anyone experienced same problem?
I am running KK4.4.2 fyki.
Thank you very much for your kind help!

are you unlocked, rooted, custom recovery, rom, kernel, anything? can you access the bootloader?

If you're stock, it could be hardware. Though have you ever attempted to root?
Is it just randomly happening?

Yes, it just randomly happening. It started yesterday morning until now..
The phone started to not responding at all and then my screen goes broken (same screen as broken TV I might say).
If I let it cool for 15-20 minutes the phone is usable, but then after 1 hour of normal usage the phone started to freeze again.
Just curious, none of you experienced the same?

this kinda looks like the static i was getting on screen on my n7 2012 when i let the battery get too low. charging it up and a few reboots fixed it. but im not sure if that's what is going on with yours

I just got mine, 32gb from the playstore, a few days ago, and nothing like that.
If it's happening when your device is hot | overheating, you may wana see if you get it replaced.

It happened to me once. The phone was with his screen off and when I try to turn it on that exact same screen came. But it just happened once, also I experienced random poweroffs and reboots. I did a factory reset and power off issues and freeze stops, but had one reboot once I start installing my apps. I think its a software issue but I'm not sure.

I'm glad (and kinda of sad) to know that I'm not the only one with this issue.
The problem started about two weeks after I bought mine(Telus). It's done this about 5 or 6 times,randomly.
I found that having someone call me will "unfreeze" the device and the screen gets back to normal.
The first couple times it happened, I was running stock 4.4.2. I since rooted it and installed Xpposed/GravityBox and I'm still getting the problem...
I think that I'll have to return it...

Hi, I have the exact same problem, I posted a video on youtube /watch?v=m0EkC_ak01g but I got to the same conclusion that it might be a GPU issue. So there is nothing I can do right?, the worst thing is Im in Argentina and LG dont take my warranty because I bought it in Germany. So there is absolutely nothing I can do?, I know how to avoid the flickering a little bit, when I hit "Ok Google" button it seems responsive and as long as I touch the screen it works (you can see it in the video) but as soon as I stop touching it, after 2-3 seconds it becomes unresponsive again, and when I say unresponsive Im saying the screen doesnt reflect what Im doing, I can still push the buttons and all. So Im not 100% sure its a GPU issue, but a software too. Thanks.

Messed-Up Display

Hello XDA,
My Nexus 5 running CM12 5.0.2 nightly will not respond to the touches anymore infact when I press the power button to activate the display it acts as if someone is touching it randomly messing all the apps that are running and opening and closing many other things.
Furthermore it displays weird and burned lines throughout the screen. It was not dropped, no water went inside the device or anything. If it helps I did install the OTA updates that CM gives us.
I have also attached pictures so you may get a better understanding of my problem.
Thanks in advance.

I hate to be the bringer of bad news - but your screen is toast. Fortunately you can replace the touch and display components all at once.
http://www.amazon.com/Skiliwah-Digitizer-Assembly-Google-nexus5/dp/B00HN0U168
Here is what you need to perform the repairs - and here are the procedures for disassembly.
https://www.ifixit.com/Teardown/Disassembling+Nexus+5+Display+Teardown+-+liquid+damage/32410
Trust me, it's not that difficult. Unfortunately, it's a bit pricey ($60 for the screen and digitizer), nevertheless much cheaper than a new device or sending your device in for repairs.

Rma

Problem Solved
The screen isn't toast, neither is the digitizer. I have 2 of these phones. The parts which cause problems like this are the main board and the ribbon with the USB connector on it, which also attaches the screen & digitizer to the main board. One was showing lines exactly like this, & also no touch. I put a replacement main board in. Works great now. The other, wouldn't even turn on. I put the main board from the first phone in the second one, it still wouldn't turn on. I replaced the ribbon cable, it turns on and perfectly replicates the issue from the first phone. So now, I have one fully functioning LG Nexus 5, and another which turns on with the same problem as yours. This is good, I started out with 2 of them that were useless to me. So, it appears that your display and touch issues are caused solely by a bad main board. A replacement main board costs somewhere around $75. After swapping stuff around, I have 2 bad main boards, 1 bad USB ribbon & 1 working phone of 2. Not bad, not bad at all.

Nexus 5 Black Screen, But Still Working

So my Nexus 5 (a couple months ago) has started to just randomly go black. I get notifications and stuff, and the backlight but no display. Not sure what to do or what part to replace. Would flashing/rooting help at all?

Appears to be a hardware problem.
Was the phone every dropped or exposed to water/moisture? Possible loose connection inside?
No way to tell for sure if the phone needs a new screen unless you are able to test the motherboard in another N5.

It's been dropped a couple times but not like any major drops or anything. Im pretty sure I checked all the connections inside and they were good. Im starting to figure out that the phone has to be off for a little bit then I have to charge it and turn it on and it works again

Sounds like it could be a damaged lcd or lcd connection. If it can work after being charged while powered off, could be battery or USB flex cable issue.

Ya I figured out I have to reboot it a bunch of times then it will work

I think it might be the battery because this is my dad's old phone so it's been in use for a solid 3 years.. I wish I knew for sure though

So I have discovered that if my screen is on for a while the task bar at the bottom starts to shift up and down

Have you found out more about this? I think I have the same problem. My phone never turns black while I use it. But when the screen is off/sleeping, it sometimes won't turn on again. So a force reboot fixes it. Sometimes this happens a lot, some times it works fine a whole day.

Maybe, I don't think so. My phone was useless, black screen on every screen unlock. But namelessrom took that away, so that tip about nameless was for those who have the same black screen I had earlier. But now I have the same black screens as you do. Anyway, if you want to try it out, nameless-rom.org

Happens with my nexus too. The screen goes blank randomly ..... But i have managed to deal with it.

Its happan to me also, with 4 nexus 5 of my family.
Is a firmware problem?

I'm trying to buy a new flex cable to see if it will help I'll update when I find out

You're replacing the USB charging flex cable? If you are, be careful with cheap third-party replacements as I have read reports of people having issues with charging, signal, or speaker functionality after installing the cable.

Ya so i sent it to LG finally and the diagnostic said that it was a flex cable issue which I was sure that it was anyway but I have a confirmation now

I've had a similar problem when my display suddenly started failing. First, there was colourful bands over the working display, then colourful static only and then black with backlight only. Bought a new phone, left it for a year and today after digging in the phone for a while I found a fix. The connection between the motherboard (the top bit) and the daughter board (the bit below battery with USB and connection to display) was somewhat loose and when pressed on, the display worked beautifully. I stuffed the insides with some tape to maintain pressure on the connection and phone works great.
Might not work for your problem, but it's worth a try if you're out of warranty and have tools to disassemble the phone.
