[Q] Screen problem (blurry screen on touch)

Hello everyone.
Yesterday, I got weird problem (in one hand). Phone screen on touch becomes blurry, like it's liquified... This never happened before and I believe it's hardware problem. Here's YT video which shows whats happening:

There is something pushing on the screen from behind. Push hard on a laptop screen or anything LCD and it will do that. It's to do with how LCD works.

I know, but how come it happened out of nothing? Phone has not been opened...

Friend of mine who works in T-mobile told me the same thing. He said I should wait for it to stop working and bring it to service as I still have warranty.
Thanks everyone.

cool mate
hope u will get the phone back to u hands asap.... so that u can explore and enjoy sg3

Hmm, my cousin had the same in SG3, but it dissapeared. He doesn't do anything about it, just it was gone after some time...

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.

[Q] Help NEEDED Touchscreen insensitivity issue

guys my phone started having that ODD TOuchscreen insensitivity problem which was posted here in some previous threads
and like all of them it started for me This rainy season, after 2 years of using without any problem
the problem as you know...
is the touch remains functional for like 2-3 seconds after unlcking...that too if you havent used for a while
after which it becomes barely unusable as the touch becomes unresponsive..
its like the options key and the back key are being pressed,
pressing the home botton will end up being the screen getting captured
there was a solution of heating up the phone using a hairdryer etc..havent tried...
the option of getting the screen replaced...but for some even after getting the screen replaced
the condition right now is such that even pluggin into charger aint helping

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
PS, no problem man, I know exactly how u feel lol

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.

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.
