I have the Captivate for almost 2 months, but I think this issue is valid for all Galaxy S phones.
Some weeks ago it appeared a stain/smudge on the middle of the screen that can be easily seen with a light color background. Also, I noticed that its seen even with the phone turned off. See both photos attached.
I use invisibleSHIELD. Since the stain is noticed even with the screen turned off, I'm wondering if it may come from the protector instead of the screen itself.
It would be easy if I removed the protector, but if I do so, I'll loose it.
Has somebody had that problem?
May it come from the screen protector?
Thanks
I would imagine that it's the screen protector and the actual phone screen. Just take the screen protector off.
I don't have this problem but you can remove the screen protector and reapply it easily. Just use tape to lift it off the glass and rinse in a bowl of warm water with a drop of dish soap to clean and reapply. I've done this to my screen protector 5 or 6 times for various reasons.
yes my friend this is caused by the screen protector. mine had the same issue. apperantly its from using the squeegy tooo hard!
Could be your LCD Has a burned in Image
If you remove your screen protector and still notice the screen smudge try tilting the phone slightly to get a good angle and try o see if the smudge is internal, if it is I would say its a bleeding LCD, I had this issue with a HTC tilt at&t sent me and they sent me a brand new one free of charge.

It was applied by a authorized ZAGG reseller. I watched and he didn't use it too hard. Any way, I'll remove it.
You had this problem with a invisibleSHIELD by ZAGG protector too or other?

When you had this problem with HTC, were you still able to see the smudge?
What kind of case is that? It looks very slim and pretty cool!

It should be covered under warranty still. Their site offers a 1 year warranty so you should be able to take it back to the seller and get a new one installed free
Its the case from at&t, its like a silicon plastic thing. Lol. I got it too.

I have this same issue with my HTC Magic, that has a screen protector on it. There is a similar mark,smudge on my screen, as a result of a particularly large raindrop hitting my phone. Based on this thread, I can breath a sigh of relief that it didn't damage the screen!

The tilt is a whole different beast... the Samsung is a capacitive touch screen while the tilts were pressure touch...
I used my Nexus S without a screen protector, and there was one day when I was using the phone heavily, this part of the screen felt a little rough to the touch when I was swiping it.
Now when I look at the screen I see these faint track marks on the screen that aren't scratches, but it's like something smudged the screen. I have wiped it with microfibre cloth (My Oakleys pouch) but I can't remove this smudge.
It's barely visible when the screen is on but you can see it if the screen is off.
Does anybody else have this problem? Is it a scratch or can I wash this off somehow?
I have similar spots... it's most likely the oleophobic coating wore off in that area. Not sure how it happens, but it seems to be ****ty coating.

I also have one such small spot that is only visible when the screen is off, and only visible at a certain angle with a lot of light. It's been there since I got the phone. It actually looks like it's under the glass, but I can't tell for sure. I can't feel it. I've been keeping an eye on it and I'll utilize Best Buy's protection plan if it gets worse. Im glad I'm not the only one, but this is a little disappointing.
It's problably the oleophobic coating like others said. I have the same thing on mine, and have been thinking of exchanging it because of it. But I think I might as well keep it, as this phone has no other problems, and I'm sure it will probably wear off any phone I get with due time.
Take a paper towel and lightly go over that area. I bet it comes clean so you can't see it anymore until you wipe your oily fingers in that spot again. It seems oils like to get stuck in those spots unless you clean it with something that absorbs oils, and isn't reused over and over.
Thanks for the replies guys. Yeah I am hesitant to do a return as my phone works great with none of the issues faced by others.
I'll try cleaning it as suggested. Thanks!

I had the smudges that Kayatoast talked about. I just wiped it off with a paper towel and it disappeared. I guess we must clean it with something that absorbs oil.
My smudges probably came from the hand lotion...
I've also decided not to return mine because I don't want to get a replacement phone with a worse problem.
As for wiping it off, this may work for others in some situations, but the spot on mine is definitely a blemish/defect. Cleaning it has zero effect.
I used iklear to clean the screen then wiped it down with a microfibre cloth. That took care of the smudge. Then I slapped a screen protector on it and that took care of the smudge..now to get rid of those air bubbles..lol.
I recommend this brand: http://www.protectionfilms24.com/pr...geraeteklasse=7&marke=Samsung&modell=4603&go=
Arrived in 2 days, made by 3M and doesn't affect my screen clarity at all.
I just realized the same type of smudge on mine today. It's not on top of the screen, but seems like it's under it. Like others, I didn't want to exchange it because everything else works fine plus I'm out of my 30 day period with no exchange.
If I remember, I'm probably going to do a warranty exchange before it ends.
When I was cleaning my screen to put on my cheap eBay screen protector, I noticed the same smudge in the middle of my screen. No amount of cleaning removed it completely. On went the screen protector, and "Voila", smudge disappeared .
BTW, the eBay screen protector is very close to screen feel as the naked screen and is completely clear. Free with the $3.99 shipped silicone case... gotta love eBay!!!

You know, I thought this was a joke until I got the cheap screen protectors that came with the S gel case. Yeah, it disappears. Weird since it looked like the smudge was under the screen.
Phew im glad im not the only one, the smudge is barely noticeable except under light and while the screen is off. Going to try to clean it.
Is the smudge you guys are talking about, blue by chance? I have a slight blue streak underneath my screen since it was purchased. To best describe it, it looks like a shiney blue streak from cleaning with windex that never dries.

Does any of you proud X owners think that if one applies the a screen protector incorrectly (bits of dust between the protector and the screen) or something similiar, that it could cause the screen to scratch, having a sand-like effect? I'm really paranoid about the screen when it's naked...
btw. how the hell am i supposed to put on a protector without air bubbles? Seems impossible.
I dunno about the first question. But you're supposed to be able to put it on using a credit card to smooth it out as you apply it. In saying that, I've never done it successfully

I doubt having anything under the screen protector would harm these screens. The junk stuck under it isn't going to move as it's stuck in the adhesive.
The best way to apply them (for me anyways) is to clean the screen with an LCD cleaner (or make your own), use tape to blot up anything else, wipe again.
Next--I have found by taking the first layer of the film protecting the screen protector upside down works best. Dust and debris can fall and settle on the sticky side. Then carefully apply. As long as you don't touch the adhesive side, you can pick it up and keep applying the protector until you get it right. You want the top of the protector just about even with the AT&T globe.
Enjoy.....
By using tape do you mean using scotch tape, sticking it on the screen and pulling off?
I'll try washing my screen protector, drying it up, cleaning the screen with MF cloth, taping it up and then hopefully I'll be able to apply it perfectly! :fingers-crossed:

If you trap a particle of dust under the protector that has a hardness greater than the screen, yes, it will eventually scratch the screen in that spot.
However: Gorilla Glass has a Mohs hardness of around 9, which means there is not a lot in the mineral world that can scratch it. The likelihood of your trapping something like that under the screen protector, if you apply it correctly, is not great.
You should be able to remove a particle big enough to scratch your phone from the screen protector without having to wash the protector. I think you would ruin the screen protector if you wash it.
I've used packaging tape as it leaves no residue. Done it for years before with iPhones before owning an Android.

When you apply your screen protector, do it in a washroom with a hot shower running. The steamy air will prevent dust from getting under it.
I will try that out. I always seem to get a bit of dust or lint on the corner of my screen protectors.

Just don't wait too long, not sure if the humidity sensor would get affected.
The way I do it: obviously, I clean the screen then remove completely the clear layer from under to make sure no dust will fall in. I'm holding the screen protector with the tips of my fingers on the sides and gently bend it across (the long) median then align with the phone's screen (this is the hard part). Put the screen protector on the screen at this stge the contact area will be the median line, and then use a credit card and work your way to the eges (one side at a time). I never got any bubbles under this way. I caught some dust particles few times though. It takes patience but it pays off, currently I have no dust or bubbles on it.

If the particle is trapped in one place and can't move, I don't see how it can cause a scratch.
Plus, if any dust gets on the screen during the application process (as long as you've done a halfway decent job), its probably airborne. So its not grit or sand or anything like that (which would just fall to the ground instantly) but more likely skin, ash, etc.
A little preparation and a few tricks will go a long way to a good screen protector install. My process is:
1) Use a wet apply protector. Don't know why, but I've had vastly better results (no dust under protector) with wet apply rather than dry ones. I got to the point where I can do a dry type almost flawlessly, but only after lots of practice and a great amount of care. But even so, there still tends to be a dust particle or two. With wet apply, the first one I ever tried was perfectly dust free with little effort, and the subsequent ones also.
2) Before starting, examine the protector and see how it fits on the phone. With the backing still on the protector, place it on the phone's screen and match up the openings and edges to familiarize yourself.
3) As previously mentioned, use steam to pull dust out of the air. I run a hot shower for 5-10 minutes, then apply the protector in the bathroom. It won't eliminate all the dust, but makes a big difference.
4) Wipe the screen off with a micro-fiber cloth (often included with better quality wet apply protectors).
5) Blow off the screen with a can of compressed air (the kind used to dust electronics and whatnot) to get rid of any remaining dust.
6) Spray the application solution. Quickly apply the protector. As another mentioned, don't hold the sticky side up after you take the backing off, or it will instantly catch dust. Put the protector on quickly, don't let the sticky side touch anything but the screen. Handle the protector as little as possible, and by the edges.
7) Squeegee the protector down with a credit card (make sure the edge of the card is smooth) or some protectors will include a rubber squeegee. Blot the excess moisture at the edges. Then leave the phone alone while it dries.
The best investment for my smartphone has been Ghost Armor. I have spent so much money on packs of screen protectors. A couple years ago I decided $45 was worth it if I only needed to do it once a year. You won't regret it, and you don't have to install it.

I've also heard horror stories about peoples phones not working after they are done or the screen not functioning afterwards. And since you sign an agreement they aren't liable

I replace about 3 screen protectors a year (bought from amazon clear ones, 3 for $1.99). Other than a little rainbow effect when the screen is off, no regrets looks just like glass. I've been through many protectors before (ridiculously many on my first 'smartphones' rip moto ming, touchpro 1&2) but I can't justify the cost anymore, I'd rather have none (since I change my device every 8-12 months).

Screen protectors that come in packs are crap. The higher quality kind that cost $15 or so (Skinomi, Zag, etc) are in a different class. I've had a Skinomi on my One X since release (May), and one on my Flyer for almost a year and a half. Both are still looking great.

Not sure if this is still relevant, but I will put a vote for Ghost Armor as well. I have it for all my devices and it's like there's nothing there. Crystal clear and screen responsiveness is great. Had Zagg before and the orange peel feel and stickiness made me remove it. Those cheap packs aren't great either, they scratch up very very quickly.
Noticed that from the place where my thumb usually makes up/down scroll is strange area, and even I clean the screen, this area is still there. See Yourself - I made a picture, clean screen, water steam (breath), and this middle area is the problem. My thumb is normal, I'm a normal user and I had newer such problem with any phone.
Is the Gorilla Glass really so bad or is it coated with some stuff which is just coming off?

No, I have not used any kind of screen cover, but seems that Moto G screen is covered with the the water-resistance coating and this is failing off - it's clearly visible when cleaning the screen with some liquid, only this area stays wet.
But I don't think this is normal behavior. I can't imagine what the power users screen is now or will be later. I contacted with the Amazon ( I have one dead pixel too), let's see what they say.

If it contains a dead pixel better get a replacement, all the best for that.
BTW water repellent coating is done on the internals of the device.

I know about internal coating. But as You see, the screen is also coated. I have the proof.
I made a test, sprayed water to the screen, and as You see, the damaged area stays wet, while the rest rejects it.
The question is - do I have faulty screen or this will happen to everyone sooner or later?

well you are the first one to report something like this and i agree with you because this might happen with others also sooner or later. Its very much possible that your screen is faulty since you mentioned its new (maybe the screen had tiny dust particle before the coating took place) many members are using the phone without any screen-guard but none have mentioned anything like this..A lot of member have got dead pixels on their screens and got them replaced.
I'm using a screen guard since the screen will get scratched over the time.

Well, Amazon just replied and they will replace it with the new one, so I have to wait for the new one and later send the old one back. Let's hope that this one's screen ( I still don't like to add the screen protector, as it's kind of ugly) will last longer.
If you apply the screen protector carefully, you won't even know it's on! It's your choice tough but what you reported is pretty worrying. That area of the screen seems too big tough for it to be a thumb, (you touch with just the tip of the thumb) do it was probably already a little damaged when you got it and with the time it got bigger and bigger. Or maybe you scratched your screen somehow?

the is an oliophobic coating on the screen of the moto g (part of the gorilla glas). this is also the reason why you generally get less fingerprints on the display than on a screen protector and why it's much easier to clean the display than the scren protector

I'm 100% sure that I haven't scratched the screen purposely, juts normal, id even say careful using. And if I clean the screen, it's bright and like a new, impossible to detect any damages, also this problematic area is clean and shiny. But when I touch it or spray water etc, it's clearly visible. So choices are:
1) Add screen protector (let someone do it, once I added it to iPhone and the result was terrible).
2) Polish the whole screen, so that this coating is removed.
3) Replace.
4) Ignore.

Yes, You are right, it's anti-fingerprint oleophobic coating and be warned, seems it's just won't last.
So my idea worked and i now have a full adhesive screen protector. Covers from edge to edge and there is no halo effect. The protector is on good and does not peel/pop out. I am using a unicorn beetle pro full body case and no problems. Before the case would pop out the protector but not anymore.
What exactly was your idea?
How did you manage this? (For the people that haven't been keeping up with your posts, such as myself.)

One of his older posts discussed using LOCA. If you use LOCA, how do you get it off if you ever want to remove the screen protector?
Yes I used LOCA glue. To take it off you just heat it. It should be easier to remove than when replacing the digitizer.
I got a couple air bubbles though but id rather have that than a scratched up screen lol
Interesting.... but more info on how to do it and what products to use would be great. Thanks OP.
I was just thinking about if this was a solution two days ago, but this is exciting news that its worked. My question is, is the LOCA a problem to handle, because i could see using too much might have some go into the speakers or just seep from the borders. when originally applied. and is there a way to make sure we don't get bubbles?

Yea i got a little on the speaker but you just have to be care full and as it seeps kut clean it with a rag. The good thing is that it wont dry until you put the black light on it. The part you have to be the most carefull with is the home button. Loca will make it sticky and a little harder to press. I also reccoment you get a protector that is completely clear as the one i got has black on the top and bottom and it prevents the black light from drying the glue under those areas. Clean the screen good. To avoid bubbles look at youtube and see how they apply it. Basically a stick figure but instead of a head it is a y shape. Carefully place the protector and let is slowly spread on its own. Once it stoos spreading then you could slowly press down on it and remove the remaining bubbles. I lined uo thw home and back buttons first and made sure the cut outs were aligned for the camera and sesors. Then i applied the black light on the bottom half furst so that it would align properly. I did this while pressing down on it because the air bubbles kept coming up. I also covered up the top half so that wouldnt dry up. Oncw i got the bottom i got rid of any air bubbles on the top half and did the same. After that i put the phone in a box., close it up, do a cut out for the black light to fit and let it sit for a couple minutes to dry more. Then i cleaned and dried the edges. Make sure not to leave too much of the loca in between the screen and protector so you wont get touch senaitivity issues. And do it where there is no dust. I oly got 1 small air bubble but some like white spots that appear to be dust. And again clean the speaker, home button, sensors, and camera before drying. You could also just scrape it off with a plastic blade that the loca came with. And make sure to use liquid version and not the film.
