[Q] Smudge/stain/spot on the screen

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...

Screen toughness

Ok, so I decided to be brave, well kinda. I have to send my mt4g back for a warranty replacement so I decided to see how scratch resistant the screen is. I first took the edge of the metal micro usb charging wire and tried scratching the screen with that, didn't work. I then went and took my keys held one key and started scratching it against the screen (like you would sharpen a knife) nothing no scratches. Tried with harder pressure... still nothing.. then took the whole set of keys and swirled them around the screen to simulate them being in your pocket bumping around.. I put a pretty good amount of pressure.. and still nothing! It did scratch the chrome bezel a little around the screen it did not make a single mark on the screen. For not being gorilla glass the glass on the mt4g is pretty tough. I was impressed I couldn't scratch the screen... I was just trying to see how well it would hold up in a everyday situation like having it in your pocket with your keys. I just tried again hacking at the screen with a key, harder than any other time before and still not a damn mark!

From what I was reading it's not gorilla glass but it is a high tempered glass. I really tried to scratch this thing with a key though. I continued trying even after this post. Still haven't been able to make a mark on the screen with a key.. and I'm not being delicate by no means.

Glass is pretty tough. And metals such as keys won't scratch it as its much softer than glass.
I don't remember much from geology class but there's a few rocks that can actually scratch glass.

graffixnyc thanks for providing us with actual BRAVE data lol guess we can rest easy now. I always knew it was using high tempered glass and was scratch resistant just keep in mind it doesn't mean its scratch proof

Yeah, I wouldn't take it and slide it across the sidewalk on its face but its good to know that its pretty tough and that having your keys in your pocket or something like that wont scratch your screen. I honestly don't see a point in a screen protector for this phone after this. I mean anything that's tough enough to scratch the screen would probably rip through a screen protector.
I tried really hard to scratch it with the keys and nothing, even after this I kept trying and no dice. I'm pretty sure sand or something like that could probably scratch up the screen but its good to know in average situations your screen is safe.

this is sorta on topic...while the screen may not scratch very easy...the damn thing shatters with the smallest drop it would seem
was just at my local tmobile store and while i was there i was playing with a g2 while waiting for my paper work and next to it was a guy looking at a mytouch 4g...well we started talking about how good the phone was...turns out he had just bought one and was waiting for the girl to come from the back and give it to him
so myself and the other dude walk to the counter together talking about the phone...i grab my paper work and as i do the girl goes to hand the customer the phone and she drops it on the counter and the screen just shattered from top right edge inwards...was pretty gruesome...it was a fall of maybe a foot to a foot and a half
im pretty sure that phone had to have a weak spot or something in the glass...cause there is no reason that screen should shatter like that from a foot drop...needless to say the store manager saw what had happen and told the girl to get the customer a new phone from the cabinet
i can say now though im going to keep a tighter grip on my phone from now on

Lol freek91 that's another thread of its own. But believe it or not I saw first hand like you how weak it is as I saw my friend drop it from his lap and thing shattered badly but it worked. I read similar feedback online that's the reason I am very anal about getting firm grip always and wasted $50 on case...
Sent from my HTC Glacier

if you drop the device, there is great chance to crack or even shatter the screen, and moreover, if you slide it over the surface of concrete, I'm sure the silicate/siliconate will have a great chance to scratch your screen.
The point is: take a tight grip of your device!

broke my screen, replaced it for $30.
Touchscreen is easily broken due to stiff frame.
Using TPU case makes it almost unbreakable....drooped in case several times from approximately 5ft onto concrete with no damage.
Get TPU case...run about $5 and look good

I'm on my 4th one, due to the SF vs. SO issue, and my first one's screen got scratched in spite of being in the babying period. Not in a bad spot, but 2 clear small scratches that would be a problem if in the visible part of the screen.
So I didn't find the screen to be scratch resistant (maybe the SF and SO are different), so when I got one with a good screen, I put a protector on it. Which helps with fingerprints, too, so that's a win.
I wish it was gorilla glass. I had the Vibrant for 14 days and it really seemed to have a strong, scratch resistant screen (and, dare I say it, a vibrant screen).
Just another data point.

Screen Scratch - EASILY SCRATCHED.

I know this probably shouldn't be in the General Section but I just want to help people out! Beware, The HTC Sensation does not have proper gorilla glass, gorilla glass does scratch but not that easily, today I handed over my phone to some friends and I saw them using the phone very carefully but when i got the phone back there were BIG scratches here and there on the screen! Whoever hasn't bought a screen guard PLEASE do so and remember NOT to buy the glare screen guard, but the Anti-glare one. The glare screen protector doesn't work that well under the sun and most of the time you see yourself rather than the UI on the screen even in full brightness. The Anti-glare protector works PERFECTLY.
And also guys, please help me out. The scratches are really minor but irritating. The aren't visible when holding the phone normally or looking at it from the front but when i tilt the screen I can see them. Would getting a screen guard help? Would it hide the scratches?
Sorry if this has been posted already..

I had a couple of scratches on my screen so I put a zagg screen protector on. I can't see any scratches on my screen anymore.

Thanks a lot for replying. Unfortunately, that company isn't available here in my country. So would a normal screen guard by a good company do?

Before I returned my old unit for some issues, I did a scratch test using keys and the blade edge of scissors. I couldn't make any scratches although I was hitting the screen fairy hard...

Sorry for repost and BUMP - Is amzer a good company? Should I order the protector?

I always keep one pocket free for "the phone pocket"... I mean sure it's gorilla glass and all, just like my galaxy S was, but I don't want to test it out!
Sorry to hear that the OP was having issues. It seems very strange that a finger could cause scratches like that... Was there some kind of debris around? Like sand or something?

It is Gorilla Glass, and it isn't scratch proof:

It's not actually a SCRATCH! Like a hard one, it's big thats why its visible when i tilt my phone and when i put my nail across the screen to check whether it's a scratch, i can feel it.

I think any screen protector will work.

You aren't getting a reply , because people don't know. Buy one and see for yourself. Screen protectors aren't expensive. I just bought 8 for under 10$

The hTC Sensation has Gorilla Glass

It's because your screen protector, those things aren't scratch proof. I had the same problem.

Oh wow, even the G1 used Gorilla Glass. That was long time ago and before other manufacturers started bragging about their Gorilla glass equipped gadgets. The same goes for back-illuminated camera sensor. Only Apple made a big deal out of it, while EVO 4G (saw it in iFixit teardown) and possibily also other HTC phones also used back-illuminated sensors.

again i had my phone since 6/16/2011 it stay in my cargo pants pocket with keys and everything else still my phone have know scratches all i get is finger prints wich is supposed to be finger print resistance

I may not call it a scratch. It's just irritating ordered the amzer protector.

evo 4g was supposedly gorilla glass. The one day i was rocking it without a case (the superbowl, i was a little buzzed) my buddy took me on a beer run got out of the car with phone on my lap and it skidded across the cement screen down. i flipped **** picked it up only to have a scratch on the top left plastic the screen was fine.
So you let you friends see ur phone and they handed it back with scratches? Id beat some ass thats not cool

Who isn't using a screen protector?

If not, any scratches? Even light scratches?

none so far

I'm not and o have yet to discover any marks still want to invest in a screen protector but its hard to find a decent one!

I just took mine off and now the screen looks SOOOOOOO sexy and feels so smooth.
I would hate to get scratches, but I'm going to take the risk. It's just so much better without a screen protector.

I have a few small scratches on my screen, but they are very light scratches that do not affect the look of the screen. Half the time I dont notice them unless I hold the screen so it shines in the light...

I have one cm square of scratches, stupidly put my keys in my pocket with the phone :'(

I had a screen protector for a while, but took it off because I botched the install and it had too many bubbles. I actually took it off to install another protector, but I liked it so much naked that I left it. Been that way for 3 weeks and I haven't had any scratches. Don't drop it, don't put anything next to it in your pocket, and in general be careful with it and it should be fine.

Running without and no scratches at all. Feels better without the condom.

No scratches yet.... waiting for the protector to come in the mail.... followed by a case

You should invest on one quickly because mine scratches pretty easily. And I don't even have nails. Lol.

I've used it without a screen protector for my first one and no scratches. I final put one on my 4th Sensation. I used the Skinomi and it feels nice and thin. Was worried about it not feeling as smooth, but it is nice and very responsive still .

i'm not using it , i had HD2 for 2 years and even my ruff use which made the battery cover looks crap but the screen was so clean of scratches so i don't feel i need it for the sensation , just got a good case to protect the back and the edges and THAT'S IT

Its got gorilla glass...so how could it even suffer from scratches in the first place?

Get one ASAP! i didn't have one on mine the first month, and it's scratched in the bottom part, and some other places around the screen, and i have been very careful with it, i always carry it in my left pocket, where i doesn't have anything else, and never lay it screen down etc.
My old hero has a lot tougher glass than this one.

Drag a diamond across the glass and report back?
Kidding aside, the screen protector in the accessories forum feels almost as good as bareback.

I ordered two when I first got it, but I am yet to put them on, I need a some form of sticky dust remover to remove the fine particles/lint from cleaning (almost like contact but not as much adhesive, like a removable/reusable sticker).
I never got any scratches on my old iPhone with the crappy $10 replacement glass and digitizer from ebay, so **touch wood** I think I will be fine.

im not havent since i got it. No scratches at all with normal everyday pocket use. i mean its a risk but everyone knows its better without a condom

same here, never used a screen protector on my phones. My old Sony P1 still has no scratches, used my HTC Desire for a year without a cover and it has no scratches (on the screen that is) and had my Sensation for while no, no marks on the screen what so ever (I did get the first scratches / parts where the paint is gone) on the side because I dropped it two times in a row :S.

What I said in another thread..
xSeany said:
It's a personal preference. I've had my phones bare. (MyTouch 3G, Nexus One, Nexus S, G2, Droid 2)
I've only had a case for my Nexus S, because it was really cheap at work and was the same concept as the Otterbox. I've tried Zagg sheilds on my Nexus One, Nexus S, G2, and Droid 2. And I can easily say they bug the crap out of me. I can feel a difference in quality of touch response, as well as comfort(too much friction).
However, some people live by these products. I can't stand them though, and I've tried to get used to them. They're great if you're careless about your phone. I always make sure my keys are in my left pocket, and phone is in my right pocket. Out of all the phones I've owned, only the Nexus One had a scratch on the screen, and it wasn't really noticeable. In fact, I would still use it, if there weren't dust/sand underneath the screen(left it in sand at the beach for about an hour one day....).

So no, I dislike screen protectors, and most cases for that matter. But I'm more likely to use a case than use a screen protector.

No scratches what so ever. I do have a dedicated pocket, Lefty, for my phone. That is all that goes in there.

I think the majority of all new phones comes with Gorilla glass now. Can't wait till gorilla glass 2. I have 2 small nicks on my htc sensation 4g though...don't know how i got them...but they are definitely there. I've had my phone for 1 year now and no other scratches.

Specs state that it does but I personally think it's no better than other glass. I forgot my keys were in the same pocket as my phone, took it out and found scratches afterwards.

It definitely is. No screen protector for something like 7 months. The only scratched are microsized and only visible if I tilt the phone quickly in direct sunlight with the screen off.

Gorilla Glass is still glass, don't forget. It's much tougher than ordinary glass, but if you throw the phone around, don't expect it to not scratch or crack.

may be, but i did not test. i dont past surface protection, there was no scratch yet

Exactly. I'm not sure why people think it's bulletproof lexan...
As far as cracking goes there are certain variables to consider... ie: screen size, curvature, chassis design, etc...

Well, there would be quite a substantial increase in the price considering the extra processing it would take. Does nobody here feel the need to provide reasonable answers?

I left my phone without any screen protection and it got scratched due to having it in the same pocket with my keys. Do not think that the screen cannot be scratched easily.... ))
