[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...

WTB HTC but concerned about screen

I lost my sgs4g recently and was looking into getting an htc sensation. One thing I'm noticing is that the screens crack pretty easily (falling from 5ft). The sgs4g has gorilla glass and I would drop it plenty of times and although it would fall apart without the case(back cover and battery pops out), the screen would never crack. From what i have seen, the htc has gorilla glass yet it cracks so easily. Why is this? Is there a screen defect with the phone? From what I've seen so far, the phone seems great but the screen issue users seem to be having concerns me.

i know of a digitizer issue but an easily crackable screen? never heard that one before

ok i read a bit further and the way most people spoke of the phone,it had me think they were one and the same. the digitizer will crack easily but the screen itself will be fine am i correct on that?

Is there anyone else that would like to chime in on this? I remember reading a thread where a person asked whether if the replacement digitizer would be gorilla glass which had me think that the digitizer and screen are one and the same. Also are there any other issues with the phone besides the digitizer that i should know about?

the display and the digitizer screen are separate pieces
the digitizer is a part of the gorilla glass screen and the display is beneath that
it doesnt crack, it shorts out and stops working properly for some. it can easily be prevented. if it happens, its an easy fix and if you want a new one you can replace it i think its about 20 bucks

oh ok great how can i prevent it? and is the easy way to fix it the software update as mentioned in a stickied thread? i basically dont want it to ever look like this http://forum.xda-developers.com/showthread.php?t=1142379

All you need to do is to be a little bit carefull whit your phone ..
I wonder why are you so worried lol do you drop your phones alot ?

The Sensation is a quite durable phone... I've dropped it a couple of times with no issues...

The Sensation does NOT have gorillaglass.
You can effortlessly push down hard enough on the digitizer to get it to touch the actual LCD panel underneath. It's an oleophobic plastic.

Which brought me to another question. Is it possible that certain phones have lower quality gorilla glass screens than others?

i would say yes
just from the design of our screen (curved around the edges) it could possibly make it a tiny bit weaker

[Q] Does your screen look very smudgy?

I can't really explain what I'm thinking of, I don't have a problem with the LCD itself, but on the surface of the screen it looks really smudgy, but in a weird way. My older phone or tablets screen had fingerprints of course, but it's different on the XL. You can't see it in the dark, but outdoors in the sun (even now in winter) I can barely see the screen because of it. I'm sure you know what I'm talking about if yours also loook like mine.
That's the only reason I use a screen protector, but I don't like the feel of the screen protector so I'd like to remove it.

I know what you mean, I'm facing that too. I think it's preety weird since my Defy from 2010 doesn't look like that at all when I use it.

And do you use some kind of screen protector or you just have to bare with it?
I bought an XtremeGuard screen protector and it looks better with it, but it feels sticky, and I don't know which one is worse.

I don't use a screen protector, since it reduces the touchscreen sensitivity. But it feels a little bit better with it.

That is because of screen is coated in a special way. Just learn to live with it or get a screen protector but then you will have to learn to deal with lowered sensitivity.

I already have a screen protector, and I have no problems with the lowered sensitivity, every one of my touch has been detected since I applied, but I wanted to peel it off because the surface of the protector feels sticky.
I'll probably just buy another screen protector, because I don't think I could live with that coating.

Screen coating is coming off?

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.

Screen protector discoloration..?

Hey guys, something weird just happened with my screen protector. It's not a huge issue but it is slightly annoying in certain lighting.
Now I've had this screen protector (Orzly premium tempered glass) on my phone for about a month and a half. Everything was perfect up until about an hour ago. In certain lighting (and this has never been like this), an oval-ish strip in the middle of my screen appears. It distorts when I touch the screen but it always pops back into place when I remove my finger. Again, it is only in certain lighting. And I can live with it.
What I wanna know, does anyone know what would have caused it? (I've used my phone the exact same, every day, since I got it) and does any one know if it will go away?

This is very common with the tempered glass protectors that don't have adhesive in the center part of the protector. Changes in temperature can cause humidity to show between both panels of glass. This is what you're seeing. As far as I know, you have 3 options:
Remove it all together.
Deal with it
Replace it with a full adhesive protector

Thank you for your quick and to the point answer! I do have 2 other ones so I might just replace it but I'll probably be too lazy and just deal with it.
Thanks again for your help!
