Serious problem with my Galaxy S Screen!!!

Hi to all,
A couple of days ago I noticed that when I answered a call the colors of the screen looked bad, and I didn't pay attention to it.
Now my screen has transparent horizontal lines which are pretty visible, kind of like interference you get in computer screens when you take a picture of them.
I would like to mention that I haven't dropped the phone even once.
I'm considering doing a factory resest in hopes that it will solve the problem, but I doubt that it is a software issue.
What do you guys think?
Please advise

Sounds like a broken screen to me. And definitely like a warrenty case. Restore stock f/w if you have flashed and return it.

Restore the original firmware (if you have flashed the phone) and call the samsung service for the assistance.

the thing is that now I don't see it at all.
It's as if it came and gone.
I disabled my task killer and juice defender, performed a complete titanium backup, in case I want to restore afterwards, and now everything is normal.
It does sound like a hardware issue, but do you think there's a chance it is software related?
I'm asking because I purchased it in europe, and I don't live there, so sending it for repair is something I would rather avoid.
Of course, if it is indeed 100% hardare issue, I have no choice.
That is why I'm asking, to be certain and to see if there are others who experienced this issue.
Your replies are much appreciated

update:
It appeared again -> Did a Factory Reset -> It's still there -> Sending for repair.
Must be a hardware issue.
Thank you for your replies.

I've actually always had slight screen issues with my Galaxy S also. The screen flickers slightly once in a while. I don't know if the radio is actually the cause but it's the kind of thing you might expect from radio interference.
Has anybody else noticed this?

Nope, never seen any flicker. My screen seems to have a defect of it's own though, but I'm not sure if it's worth the effort to send it in, because I imported mine from the UK while I live in South Africa.
When in the sun or under bright light I can see a two vertical lines near the sides and a horizontal line on dark/black colours and when the screen is off. As if those pixels have a grey/brown tint to them. The line is mostly one pixel thick but in places it is two pixels.
They are almost impossible to see unless under sunlight where they are clearly visible where the screen is black.
Does anyone else see this or know anything about it?
Edit: Apparently it's just the motherboard or something visible through the screen and they all have it, so I'm worrying about nothing...

That's interesting...
It used to come and go, but I think now it's here to stay.
It's really annoying and the screen, while usable, is really not a pleasant sight to look at.
I've attached some photos showing the problem.
With a normal screen I would say that it looks that way because that's what you see when you photograph a screen of an electronic device, but the sad thing is that what you see in the picture is exactly what I'm seeing now.
I did a factory reset, so it's in german now.
I heard some Droid X had a similar problem, but didn't know Galaxy S was having it as well.
In any event, can you confirm that after a factory reset, I no longer have root access?
Just making sure so that they don't give me problems with the warranty.

seem like the phone was dropped, and the screen got damaged
the connectors are lose

double posted again....

Really?
That's very weird...
The only time it was "dropped" was from half a meter , it didn't fall directly but partially sideways, it was with a case, and it landed on its back, not on the screen.
I wouldn't even call that a fall.
Unless, someone in my family dropped it without telling me...
Either way, I think there's no escape but to send it to repair.
If you think it's a problem with the connectors, would you try and give it to some local lab to try and fix it or send it to samsung for replacement?

I faced similar problem.
This problem only occurs when I use the phone in 2g mode.
there are occasions whereby the signal bar for 2g is full and when I place the phone near some conductive surfaces the lines becomes very obvious, to the point of irritating.
nit sure if anyone has such problems too

I have same problems with horizontal lines.
I never paid attention if i am on 2g or 3g when it happens. I will now.
Edit: rooted on jm5

-------------

It seems that my phone too has started to do the same thing since last night.
I have called Samsung and am waiting to hear from them now.
I hope this is a thing covered in the warranty.
I have reverted to the local ROM for India and have deleted everything on my device.
Yet it shows lines flickering like you can see on old computer monitors.
Its not as bad as the ones on the attachment above but it is starting to annoy me.
It usually happens when the screen is completely filled with a single color except black.
Eg. When you pull down the notification tray down.
Also I seem to notice that when the wifi is off, it stops.(I dunno maybe a placebo effect)

I have sent it to Samsung for repair, and they should tell me in the coming days exactly what the problem is and whether it can be fixed under warranty or not.
I will update as soon as I hear from them.
Until then, try to see if it changes when you hold the phone differently, for example if you grip it more firmly or hold it in another way.

When did you send it in and when did they receive it(if you were not there when they got it).
Also how long has it been without your phone?
The samsung service center is shut in my area today.
I will go to them tomorrow and get this sorted out.
Its not like the phone was cheap or anything.

I actually sent it to my uncle in Germany because it was purchased there.
He went to the store where he bought it and the store owner immediately sent it to samsung and said that probably by this Tuesday or Wednesday (so tomorrow or in 2 days) he will get an answer from them and see what's going on.

aditya_90 ,
Just to let you know that Samsung are sending me a new phone to replace the damaged one.

I sent in my phone for repairs and they replaced the LCD module. The problem is now gone.
I suggest that you should do the same while the warranty still holds since it appears to be the LCD that failed somewhat.

Strip of touchscren not working

Hi guys. I know many of you have had touchscreen problems and whatnot, i searched but it seems like this one is a bit different from usual. Yesterday the phone was totally fine; i woke up this morning and it had a lot of touchscreen problems: at first it registered touches without me doing anything, but after a couple of reboots it was just unresponsive. After another reboot and some messagging, the problem reduced to a strip on the screen simply not working. The strip is located exactly where the first notification on the status bar is (like when you receive a message and you click on that notification). I have the trueancestor stats bar buttons, so that zone is a tad more down than usual. Anyway, all I did yesterday was a quick game. I think it may be the flex cable not working because of the sliding, but it happened all of a sudden, not gradually. I must say that some weeks ago I had the same "registers touches by itself" issue when typing, but a simple reboot was enough. I tried doing factory reset, but nothing so far. Also I can't use pc companion to flash everything stock back (I unlocked bootloader months ago, even though I relocked it; I dunno if it's locked or not right now), and I can't seem to find a working flashtool download link -_-. I don't think that would help much, it probably is a hardware problem, but who knows. I'm on true ancestor 1.6 LE, stock kernel.
Any help would be great, as I fear the phone will get refused in assistance because of bootloader unlocking.

Did your phone had contact with water? When my screen had contact with water it registered touches randomly.

it didn't. it has a screen protector anyway; but that's not the problem for sure. it doesn't register randomly, simply a strip doesn't work now...

Hardware problem. Could be flex cable or digitizer.

Today there were two moments it began to work again, but a few minutes after each one the problem came back. Sigh...

Mine does that when the screen is moist or my hands are too oily. Are you sure you're working in a dry environment?

mhh... exactly that? I dunno, my hands are dry and i think the screen is too; it has a quite thick screen protector (the skinomi one), so even if it got moist that shouldn't be a problem, right? I'm now living in a different town and that may have changed something, but the problem didn't show up until now, and it was sudden.
Also, I noticed that using gamekeyboard on a certain profile I had buttons placed on the strip, and pressing hardware keys mapped to those buttons actually works. This restricts the problem just to the actual finger-touch-detecting mechanism. Does anyone know anything about this?
Edit: lol I heated the phone up a bit with a hair dryer. It works now. I hope it will last and I'll not have to do this again over and over

Weird touch screen.

Its been some days, I'm experiencing this weird touch screen problem.
My DZ touch screen doesn't respond properly.
For example:
If i see an image and slide just one finger up and down then it would zoom in and out. And then the whole screen becomes unresponsive.
It seems as if, its touched by itself. Even the softkeys would go numb. Only the haptic feedback of my search button works at that moment.
But the trackpad works perfectly.
But, If i lock and unlock the screen using power buttons, it would work properly for some few moment and then again the problem repeats.
At present I'm repeating this process of locking and unlocking screen to use my phone.
One even worst weird thing is that, if the device is connected to a charger and kept on the table or floor. This problem doesn't occur.
I have done system format, restored my nandroids and even changed Roms. The problem still exists.
Please note, i don't use any Casing or covers that would press the device hard for malfunctioning of screen. I have even removed and replaced my screen guard.
I'm sure, its not a software issue.
And even i dont think its a strip issue, because i dont use my physical keyboard always.
Can anyone say what hardware issue it might be..?
Or what i need to do? I'm really out of options.
Do i have to replace my whole screen or the digitizer..?
Thanks...

Thats no fun,
As you stated it's more than likely a hardware fault, the two most likely culprits would be the digitizer or the main flex cable
Which would be this and this
both relatively easy to replace depending on your experience
in 4.x and up ROMs check the developers setting to show touch or use apps like
z device test
or
yet another multitouch test
these wont help you fix the issue but may show you where the bad points are on the screen
best of luck

I know the problematic spot. Its near Search softkey. Even Yet another multi-touch test would stuck at that spot....
As you can see in the image, that i'm not holding anywhere, still it shows that somewhere around Search softkey its touched by itself.
In second image, If i move my fingers around, it would show the other touch responds, but if i slide near search, it would go and stuck there itself.
So, i guess i would first go with the flex cable.

In actuality I'm leaning toward the digitizer in your case, but its possible to be either.
And if you have a spare phone it may be worth disassembling even without buying anything. On a G1 I once fixed a similar issue just taking out the digitizer and cleaning the contacts on the ribbon and the edges of it as well, when I put it back it worked like new. I think some dust may have gotten into the edges but it may be worth a shot before buying anything... But could make matters worse so if you don't have a spare, buy parts first
Best of luck

I guess i should try disassembling and clean it first. If it still persists then i would go for digitizer.
And thanks for giving a hope.
Thanks...

HTC 10 Half of Display Not Working After Screen Replacement

The battery on my HTC 10 was completely shot and needed to be replaced. I'm a careful person by nature and this being my first phone repair, I bought an extra screen just in case something happened getting it apart. Followed a guide by jerryrigeverything on how to take apart the phone, got the battery replaced, everything seemed to go smoothly. When I went to test the display before screwing everything together, the new screen I installed lit up, but the right half of the display only showed as a repeating segment from the middle of the screen. Thinking the connector was loose, I disconnected and reconnected the display and made sure everything was tight: same problem. I reinstalled the original display, which I made sure had worked after cutting through the adhesive before I disconnected it, and now the old display is also showing the same issue.
The touch screen on the broken side of the display still works, I'm able to type PIN numbers and whatnot even though I can't see them properly. Only thing I can think of is maybe the connection actually got some debris or something inside of it? I don't think I damaged anything, as I was super careful, but it was also my first time opening up a phone.
Sorry for the inefficiently worded post. Any help would be really appreciated.

Did you resolve this?
I have exactly the same issue you describe after my screen replacement (with two new screens) Believing the first was a dud.
I have done many screens/batteries on my m7, m8's previously never having a problem.
I'm currently back to running my M8 and miss my 10!
Anyone reading this and has any suggestions they are all welcome!!
Thank you in advance

Exactly the same issue this guy has
https://youtu.be/RpdCuMiTOn8
I'm now wondering if it is just bad aftermarket screens?
Has anyone else replaced their screen successfully, if so where did you get the screen?
Thanks Rory

I have been having the same problem. I just tested screen number 4 that has the same exact problem. Is there a specific brand that is known to test well?

I dropped my 10 in water at work...believe it was a salty water at that. It stopped working completely. I opened the phone to check the internal components for damage and I broke the LCD doing so. I replaced the battery and the screen at almost the same time. I think it may have been a week or two apart.
The battery is still working. The screen worked initially but the phone kept getting really hot and the heat kills the phone. I tried keeping it cool at all times which kept it operational. It hasn't been activated since I quickly replaced the phone with another of my lines upgrades. I went back to the phone to check it out and try using it as a replacement for my daughter but the screen no longer works.
The battery charges just fine...the led light indicates that well. I've tried reinstalling it several times with no success getting the screen working again. I tried the original screen to check and I could see light and it was responding but its not usable so I'm stuck with a phone that has a new non-working display. I think the brand was called DIYRepair or similar.
If anyone has encountered this and has advice...I'd be happy to try anything.

Weird Digitizer Issue (Just me)?

Fellow Pixel-ers,
So, I broke my screen about 8 months ago. It had coverage and got it replaced by a Google authorized screen fixer place.
I noticed early on that things didn't seem quite right. If I pushed down too hard on the screen, my touch wouldn't register. But, it didn't happen too often and I didn't want to have to deal with arguing that they may have poorly installed the new screen/digitizer and that it wasn't 'my fault'.
As time went on I started noticing that the almost bottom of my screen would not register a touch but mostly only at night. Again, it didn't happen too often and it usually went away after a little poking/prodding/pushing/.
I also thought it might be an application that I gave 'screen Overlay' rights that I shouldn't have and it was causing issues.
I validated my issue by using a Touchscreen Test app.
When I use an app like Vysor I am able to 'access' that area of the screen even when my fingers cannot. Does that validate this is a hardware issue?
The area affected was definitely more than just a few pixels (see screenshots).
More recently it was happening more frequently (not just at night) and it almost never goes away.
I wanted to make sure it wasn't a software issue. So I planned on dirty flashing my OS (AquariOS), but actually ended up accidentally upgrading to a clean version of Android 10. Unfortunately, the issue was still there.
I then did a clean flash and downgraded back to Pie w/AquariOS.
Shortly after getting back up the issue showed up again.
At this point, I have virtually lost all touch response for the bottom 1/8 (not quite the very bottom) of my screen. I've had to use a floating keyboard because the space bar falls right in that area. Sometimes I can't click 'next' or 'continue' in apps or web sites.
Has anyone ever experienced this very odd digitizer issue like this? Any thoughts/suggestions/ideas.
I'm guessing the only solution is a new phone as it is not worth the money to fix it.
So now I'm just waiting for either the Pixel 4A or 5 to come out so I can get a new phone I guess.
I just find this very odd how specific this area of 'dead pixels' is. I always thought it was more random than a specific rectangle.
I look forward to hearing from anyone.

Hi bro, I've face the exact same issue, but for me it was at the center of the screen. Luckily my phone was under warranty, but getting them to replace my touch digitizer was a whole different thing. At first they just didn't acknowledge the issue, then I tried showing them proofs but they didn't believe as they were from some third party apps. Finally, I used markup to show them the issue and recorded it took some screenshots as well. So, they replaced my digitizer at last after constantly speaking them for 2-3 weeks. I can only suggest you that if your phone is still under warranty or you have accidental damage coverage, ask them to replace them. Otherwise, it'll be better to buy a new phone as replacing the screen from your pocket may be very costly.

For anyone who reads this thread,
I resigned myself to having a bad digitizer but was starting to look to replace the phone. Then about a week later I inadvertently dropped the phone in a pool. Unfortunately, as the screen had been replaced the waterproofing was no longer good and phone was a brick. So I never resolved the issue but will always assume that the company that replaced the screen did a less perfect job and that when a screen is replace the phone looses it's waterproofing ability
