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.

Wifi Problem - freezes sometimes and cant disable. Have to restart. LP & KK

Hi guys,
I have a problem that I've never seen or heard of before. So here is the situation:
Power button didn't work, so RMA'd phone. Got different phone back and instantly rooted/installed custom rom. Didn't notice anything until a month later. My phone would randomly just lag out and the wifi would stop. It would still show connected and that there was uploading activity, but that is all. When I clicked it to disable, nothing would happened. I would have to restart the phone, disable it for a while then re-enable it. I though it was the rom so I switched. Noticed the same thing is happening. I decided to play around with my sim, so I took it out and then put it back in, and it somehow fixed the problem. So I was assuming it was the sim causing the problem. Worked perfect for a week then started happening again. I did the thing with the sim and it didn't work this time. I still have the problem now.
Basically, my wifi would just stop working, when I click on it the phone lags out and freezes. I have to restart the phone and it will work. Sometimes Itll work for a full day then all of a sudden just stop. Sometimes it happens just a few minutes after restarting. I mostly find that it happens when the battery is less than 20%. Right now I am running stock LP, locked bootloader. I was supposed to send it in but they wouldn't accept it because I was 6 days over my warranty. So I'm not sure if I was send a faulty phone and now I'm stuck with it?
LG said I would be charged $150 flat rate for them to fix it which sucks. I'd rather just get a new phone and stay away from LG in the future.
Any suggestions? Also this was happening on KK at first then I tried LP Roms and same thing. I have never flashed any radio since I got the phone, could this be a possible solution?

You would get the same reply from pretty much any company, once it is over the warranty period then it is over the warranty period, this is no reason to "stay away from LG". Most charge a flat rate since they're likely to simply do a motherboard/whatever board swap if the fault is to do with internal components, as it is much easier/cheaper for them to do this compared to diagnosing and repairing/replacing things individually.

Try a different radio version. If it doesn't change anything then you have a hardware problem.

The only reason I said I would stay away is because it seems that I sent in my phone with a problem only to receive another one with a different problem. I'll try the radios tonight, hopefully it works.

You mentioned that you only ran into issues after a month. During that month a hardware issue could have possibly developed and the device was fine when you initially received it.

Nexus 5 extremely slow and stutter from boot after screen replacement

Hi, I replaced myself the screen (preassembled screen+digitizer+frame). After the replacement everything worked perfectly for like two hours when i rebooted it, from then on it is extremely laggy and stutters from boot animation, and when I press the power button (or when the screen shuts down), the phone itself shut down. In bootloader it doesn't seem to have problems.
I checked every connection inside the device (I've disassembled ad reassembled it several times).. thinking of a software problem, I've flashed marshmallow stock rom frist, and kitkat 4.4.4 then... but it's the same with any factory image.
Maybe I damaged something on the mainboard?
I also made a video to explain the problem:
with a lot of patience I set up a google account and downloaded cpu-z to see if maybe temperature sensor where giving wrong information to the system, but they're fine and everything seems to work propely aside from the stutter.
thanks to anyone who will help me, I'm almost giving up

I thought of that, but the fact that the haptic feedback (like the one you have entering app drawer, or returning home) is perfectly sync without lags made me think the touch was ok... and even twrp recovery was working smoothly (coudn't show in the video since I factory flashed kitkat)

with 6.0 shuts down after boot animation (and reproduces it stuttered like the kitkat one in the video).
Right after the screen replacement, stock marshmallow was working fine for a while

That's very strange indeed, OK so try this, go into developer setting and check disable HW overlays, and check force GPU rendering, this will make the phone use the GPU for UI stuff, possibly fixing ur studdar, let me kno

OK, I've just tried... can't tell any differences.
I was thinking that the main way to solve this could be to investigate on the fact that turning off the display (both with power button or by itself after 30sec), shuts down the entire device. Could this be an hardware failure? (maybe generated by a physical damage that I caused)
thank you BTW

That's very weird, what did u replace, and how did u do the replace, did u do the frame as well, and when u took the batt out did it come out easy it did u fight with it, I've heard cases of this happening, and other issues caused by damaging the battery during a fix

I bought a pre-assembled frame-display-touch. The battery came out easily even if I slightly forced it in the bottom. Anyway before replacement the battery was completely discharged... it has been completely discharged for almost two months since I broke the lcd in September. Left the phone disassembled on the desk for two days. After reassemble I plugged in a 2A Samsung charger to fill it up... initially everything was working properly, made a few photos with both cameras to check, a call and some random checks.. still on charge. On the second call I made, the microphone stopped working, so was the third... turned off the device, back on and everything was messed up like it is now.
Well a battery failure could actually make sense...

hey i have exactly the same problem with my nexus 5, i haven't opened it neither changed battery or screen but i'm suffering the same issue since a few days ago. have you managed to find a fix?. in my case it just started to do that suddenly. as in the video is totally unusable, i reinstalled latest stock firmware throught the recovery menu but with no luck, everything is ultra slow now

I didn't fix it eventually... but from my experience in fixing PCs, I believe that it could actually be a power issue related to either the battery or some power circuit.
If you've nothing to lose and some dollars to spend, you could try a new battery and see if it works!

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.

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.

OK!
I could also mention that this happen every time I unlocked the lockscreen on stock ROMs, and custom. But nameless ROM for some reason got it to this point at least. If any one have black screen on unlocking the block screen, try nameless rom...

So what your saying is to try the rom and see if it fixes it? Can I have a link or something, I don't know much about roms

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.
