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)

aditya_t90 ,
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.

Checking Motherboard when screen is damaged

Hi there, I recently had an accident with my Nexus and damaged it's screen. I did find the phone to be working for the next few days even though there is no display. Since I got the phone off amazon (I'm in India), I sent it to Singapore through a friend for fixing a new screen. However, they are now telling me that my motherboard has been completely damaged and it needs fixing as well. I do not believe that because I have seen the phone function for few days after the accident. I heard phones calls and vibrations for texts.
How do I now figure out if he is indeed telling the truth about my motherboard? Is there any do-it-yourself method to it? My friend, who has my phone, did try switching it on after putting it on charge and said that there was no response from the phone. Does this confirm my motherboard's damage?

[Q] My glide is screwed after wifi download overnight

Hola, noob here with a problem.
My rogers captivate glide was behaving perfectly fine one night when I decided to download some large files over wifi. It was also plugged in for charging and I was using some app (forgot the name) to prevent my screen from turning off so I won't lose my wifi connection. I left it like that and went to sleep. Upon waking up, my phone was hotttt , the screen still on but it has faded into a greenish color with scan lines. It was unresponsive and I had to pull the battery. Ever since then, my phone would last no more than a few minutes before freezing and fading into scan lines. I thought it was a battery issue, so I got new batteries but that didn't help one bit. I even flashed the kernel and still no help. I did resets, recovery, wiped caches, took out sd card and sims, stock builts. Nothing worked. I can't connect the phone to the computer or wall charger either. The screen would instantly freeze and fades out upon plugging in the micro usb cord.
Have anyone had similar problems? Did I fried the soc? I don't think it's a problem with the screen since it was perfectly responsive the few minutes it worked. This noob needs helppp.
I've posted a video on youtube but I couldn't link to it, but if you search "captivate glide problem" you'll see a video showing the freezing problem I have. I'm from the US also, so I don't know if I could get samsung to fix it through warranty since the phone is Canadian.

Well I downloaded Modern Combat 3 and that was like about 1Gb and the screen turn off because I didn't touch it while it downloaded, and wifi kept going so I'm not sure why it didn't stay on for you

Idk about the phone so much , but i am computer technician and it sounds like you overheated it, what we might call "burned it up".
The screen symptoms you have described are a dead giveaway, especially the lines
If this was a laptop, I would be sending it off for a reflow .
Typically, the circuit board gets so hot, the solder on the ships melts enough for a tiny bit of separation. This requires a "reflow ", where specialized equipment is used to repair the solder connections.
First, you should to a factory reset , then try to do a warranty claim. (unless u have insurance from your cellular provider, then u might check with that)
*edit, sorry, I missed the warranty part the first time I read ur post*
The next option would be to check with the guys at www.mylaptopisbroke.com
Email them, ask if they concur with my diagnosis and if they can help.
I have been dealing with them for about two years and always been highly satisfied. (They are in NY, I am in TN. I have sent literally dozens of devices to them)
If none of those 3 options work out for you, start looking for a new phone.
Sorry :-/

Sorry, but I agree with the previous poster, sounds like a hardware issue. Start the warranty process, can't know if it's gonna work til you try it.
Not to try to close the barn door after the horses have bolted, but in case you get into a similar situation with your new phone, there's an easier and safer way. When you're in the WiFi screen hit the menu button and under advanced settings there is the option to keep WiFi on during sleep. Also, as you have found out, be careful with any apps that directly control the hardware.

Had a very similar scenario as the OP described. Went to bed with it plugged in and streaming DI FM in high quality, woke up in the middle of the night by burning myself on the metal back plate. Unplugged it and pulled the battery, when I woke up in the morning after a rather worrisome night sleep I discovered my WIFI would not work unless I was within a foot of the router otherwise it wouldn't get any signal. I assumed the devices internals were damaged and that is what caused the problem, glad to know someone else aside from me has had a similar issue. Best bet would be trying to get a replacement through the warranty unless you have some type of protection plan through your carrier.

I see, thanks guys for the inputs. I had a feeling it's a goner. I can't do the warranty since it's rogers and I'm from the U.S.; bought it off Newegg unlocked without a warranty. So I guess I'm screwed.

Had the same thing happened to me. Had to send it to sammy to get fixed the had to replace the whole board

I've contacted mylaptopisbroke and they told me that phone repairs have been discontinued until midwinter 2013.
Is there anywhere I could buy a new soc??

Try mobiletechvideos.com or phonedoctors.com

I've heard of reflowing oneself by putting it in the oven at 550 degrees for 10 minutes or something. FWIW.
Not sure I'd want to do it myself, not having better information, but perhaps there's something out there some googling will reveal.

I've look at the sites, no captivate glide stuff. Guess captivate glide is not that popular a model. I've read about reflowing, but too chicken to try. I did took took the phone apart but saw that the LED is on the board itself and couldn't be detached; it's housed in some soft rubber feely box. I had a feeling it would melt in the oven.

in the options you can change it to keep wifi on all the time.. i keep mine on all day.

Yeah... I know that now... too late though.. ahah

What have you done with this?
Have you turned it on recently and found it still works?
I have a similar problem and other threads have suggested it's a software problem that might be fixed by installing a new ROM via odin

LG G4 Display problem

I have been using my G4 for about a month without any problems. Today, each time I turn on the phone, the display hiccups for a few seconds and what I see is an incorrectly rendered version of the lock screen. I don't know the correct way to describe it, but it looks like tv's did in the old days when the vertical lock was incorrectly set (yes, I'm THAT old).
Has anyone else experienced a similar problem? Anyone have any thoughts?

Yes, mine has been glitching all day. I'm mailing it back tomorrow and going back to my LG Optimus G.

I used to see that on the Nexus 5 which casually is LG. However the hardware is so different between both that I just think it could be a common bug on the display driver. Just my imagination :angel:

I had the same issue with my G4 as well, except it was the left side of the screen. I just got back from replacing it with another G4 at a Sprint store... I hope it doesn't happen with this one. It started as a subtle error and progressively got worse and reared its ugly head even more during and after I charged the battery, until it was bad and made the phone almost unusable. Im guessing its a design issue with the screen and battery.

Blue screen after serious slow down

In case anyone else suffers the same symptoms - a couple of weeks ago, my G3 started running really slowly (and possibly a bit hotter).
Booting from cold seemed to take a long time and the ui starred freezing temporarily on a regular basis.
I was waiting for an ota marshmallow update and hoped that would fix whatever was making it go slow.
I was wrong.
The other night, I was using it and the screen went bright blue and the phone then started boot looping. Sometimes it only got as far as the LG logo and other times it for all the way to the lock screen (on a couple of occasions I could get to the desktop and use the phone 'normally'). Every time it ended up blue screening and then rebooting.
Ultimately, it was dead and despite managing a full wipe, nothing fixed it.
As a phone, when it worked it was ok but cracking screen, poor call quality (only realised that when I got a different phone) and general slow downs (possibly related to overheating (and I could only infrequently increase screen brightness to full because of the warning about overheating) means that I think this phone has been fair rather than excellent.

Its motherboard problem only way to fix it is replace it with new one

That's what I thought. Phone is well over a year old, so just got a different one.
Good feedback for anyone who has similar symptoms.

I have the same problem, went to the LG service center in my country
and yes they said that I had to replace the motherboard, because the IC power is broken
the cost is around $160, 1/3 the phone price when I bought it mid 2014
I have only used my phone for only 1.5 years and very disappointed with the quality of G3 phone

same **** happened to me, they replaced the motherboard, luckily it was still under warranty.

Don't update its motherboard problem
Same here blue screen came and phone is dead. Gone to lg service center and they told to replace the motherboard yesterday.
The whole phone now only cost 1000AED and they are telling me that motherboard replacement is gonna cost me 950AED .what the heck, better to buy a new phone. Atleast i will get one yeAr warranty new phone for same cost hehe...
The updation of lg g3 software is the main reason for this, so dont update the phone to new version of android pls.

Sorry to unbury such an older thread.
I just got a new (sic) LG G3 D855. A few minutes after the official LG updates were installed, the screen began flickering, with intermediate blue screens, and consecutive reboots. After a BSOD the screen went dark, and the phone seemd to be powered off. I am not sure about this, but I could not power it on again for approx. 20 minutes. Then it was starting again, but I feel very uncomfortable about it and plan to ask for a replacement, since I have full warranty.
Before I return it:
How to I find out the manufacturing year of the motherboard and/or if there is a newer revision or something? Is it printed on the motherboard or readable via an app (e.g. CPU-Z or similar - if I can start it at all)?
Any help in this regard is very much appreciated. Thank you.
Wishing you all a great year 2020!
