Did you bought it brand new? Did you change the crystal display before?

Bought it brand new when I wipe it a few times with micro fiber cloth it disappears completely and after a while it reappears. Never changed screen or anything have the phone like a week now.

There is a coating on the glass that wears off in time. You're just seeing the damage from your oily fingers

Thanks I tried wiping it off again, and i had a note 4 screen protector lying around I placed that on my screen until i get the s9+ one i ordered and it does not come back anymore. Weird though the clicking noise I was hearing when wiping the screen seems to be gone with the screen protector as well.

S2 i9100 with pre-installed display protector???

Hello
I just purchased a white Galaxy S2 i9100. The phone was obviously sealed as it was bought from Vodafone Germany.
Now, removing the usual "brand new" display protector (The one with the phone's features printed on and so forth) ... After that, I really thought the phone had a bare LCD, I always cleaned it, etc, shiny and clean. However, after a few days I started seeing a bubble come up....
Then I realized it had a preinstalled screen protector? Really thin and I can see it on the edges of the phone...
Anyone else has experienced this?
Probably it was bought by someone else earlier who might have installed the screen protector and later returned it to the shop for some reason.
Odd. I don't think mine has a screen protector. But there was a very thin plastic covering on the home button, which I found odd.
Mine neither, if it has one you would have seen it at the front cam, the sensor, and the speaker bcz they are left out.. my home button got one too, yay
mine neither, too.
The only Protector was the thing with informations about the phone

[Q] Oleophobic coating worn off? greasy screen too easily

Hi SGS2 people. Im in Australia and bought an i9100 a month or so after it launched, I've looked after mine well,no scratches,water damage,drops but for the past week it has been streaking up on the screen so frequently,I keep grabbing towels,using my shirt,a tissue etc to wipe oil off but normal skin oils are making coloured streak lines/shimmery patterns/blurry spots.
is it possible to wipe the coating off in time and are there ways to recoat without putting on screen protectors?

Happens all the time with people who have oily skin (like me )
Use a screen protector and you can keep wiping off the oil without worrying about the oleophobic layer...

Thanks for the responses guys, I should clarify, Im wondering if this is something that happens to the SGS2 screen over time,I do not have oily skin, this has only been happening for around 2 weeks and yep, I know a screen protector will remove the problem - its a build quality/usability question, has anyone else had this problem with their screen?

I have the same problem nowadays. When I bought my phone 3 months ago I can't remember having the need to wipe the screen ever. But now, everytime I touch the screen it leaves greasy, coloured lines and fingerprints behind. Annoying. I'm constantly wiping the screen with towels and my shirt, and it doesn't help (at least not for very long time). It has to have something to do with wearing. Is a screen protector the only solution?

I don't have any screen protector, the glass itself looks like deeper somewhere... ONLY IF WET.. The phone few weeks old... Its already my second s3 phone, because the first went wrong. I dont wan't to send back again... I can live with it... I just curious is someone else experienced same thing with gorilla glass?
Looks like something is wearing off the glass, seen an effect similar on a Panasonic toughbook with an early touch screen and anti-glare coating that wore away. Afaik the glass on these phones doesn't come with any protective coating so I'd try cleaning it all off, what ever it is.
Edit. Just read your post again, did you get replacement phone from Samsung or another source? Maybe replacement screen fitted with non-standard glass?
Is it inside or outside? Its hard to tell from the picture.
If inside, it could be the glass coming away from the LOCA (liquid ocular clear adhesive) that sticks the glass to the screen

I got my replacement phone from a retailer where originally i bought the first phone, but i saw strange "damages" on the phone from the very first time.. Hard to say as damage.. but for example the screen was look like dirty between glass and bezel (or some very thin white rhing was there)... another is a thin chrome-like paint layer missing on 3-4mm at the rear camera corner.. But the phone came in an original SEALED box.. so everything was look like a factory one.. I dont think the retailer shop playing with me... but this phone really looks like a refurbished. So i donno.. I was searching on the internet about gorilla glass problems but i didnt see anything like this...

its hard to say for me also.. I guess its maybe outside, and something like the glass is deeper. This all not so visible, I just noticed today and i using the phone more weeks now... I just noticed that I always see the same "pattern" when the screen a litle bit wet or has some fat on the top from my finger... If i clean it up as its possible, you cant see at all, just from certain viewpoint - also very transparent..
The picture that I uploaded is brighted up with photoshop, and i was breath on the screen.. But always the same pattern comes back.. I cant do anything.
Strange.... I can live with this problem. However I was paying the same money like anybody else who got a faultless phone...
Just realy curious, maybe someone already has same experience...
As stated earlier in the thread, I would hazard a guess it's the glass separating from the loca.
When I replaced my own glass parts looked like that as I begun the separation.

GG2 has an oleophobic coating than can wear with time,I reckon what you are seeing is the side swipe wear areas from where you scroll home screens

Something can be true here, because that area takes the fat faster.. If i pull over a wet paper on the screen, on this place will be more water than the other part of the screen, where just little bubbles. In this area will be a continous "water-spot"..
However i dont think i can wear down in 2-3 weeks...

Well I have seen reports of this wear popping up at fairly regular intervals.....I think, as with metals, some people's sweat/oil just reacts with the coating possibly
I thinking now: it was maybe come citric acid on my fingers at my workplace. although that must be visible almost everywhere on the screen. I used more than a year long a galaxy nexus in the same conditions. there i did never see anything like this.
i think if the coating is missing on my phone, it was missing already in the box...
do you think is that possible to replace the missing coating with any aftermarket spays? maybe i'll give a try for it if someone has experience with...

I doubt it, my advice would be to learn a lesson, put a screen protector on.......and keep it on. Personally, a screen protector is the first thing I do to any phone, along with a flip case......not to everyone's taste but I've never broken or scratched a phone yet!

Yes i thinking on too, but in this case i get no replacement phone, and have to wait again around 2 weeks for the service, then start installing again everything.... I only do this with my phones in this year untill now. Suffering enough.. My prevoius phone (galaxy nexus) has an emmc bug, this is why i was trying to put another kernels, roms, etc.. finally was dead... then i bought the galaxy s3 that i used only for a day long because was stuck in earphone mode. - sending back, waiting again for another phone, now i have this.. at least works, but looks ****...
All my phones was Samsung, but i getting lost my confidence with this name... I think next time i will buy something else...

That's nothing to do with this thread, search for information on OLED screens - it is supposed to be like that.

I would suspect that your 'new phone from a sealed box' was in fact a reconditioned unit with many thousands of hours use, hence why the screen coating is worn away.
Unless your citric acid solution was very strong, like you have holes in your fingers as well, I doubt this would cause it.
Again, best advise is to fit a £1 screen protector - it can save you from more than just scratches.

Screen sensitivity, Returning mine

Hi
I got the V30 almost 2 weeks ago and the sensitivity is horrible, i have to press most apps or buttons 3 to 4 times before it responds. I thought it might have been my glass screen protector so i removed this and its still the same. Anyone else had this or heard of this?
Nope. Pretty responsive. Think most reviews say the same.
Mine is fine. My V30 and now V30+ seem to work fine.
Sent from my LG-H932 using Tapatalk Pro.
Yes mine is doing it with small items online with websites and in most apps k use even with Gboard sometimes
There was sensitivity issue in past LG phones too. I hope that doesn't make an appearance here.
I returned mine today, got a replacement , So far so good on the new one, Mine would do it on large parts of the screen, I ran an app showing screen touches and on some parts of the screen i had to tap it hard for it to register which isnt right!
Glad it was resolved thru exchange.
I've only experienced a few instances of my V30 not registering my finger press, when tapping an "accept" button or some similar circumstance, maybe just 3 or 4 times. Could have been a browser / app issue -- the issue doesn't repeat, and the norm is the lightest brush of my finger against the screen is all it takes.

Yes , no questions asked , they just swapped it outright. The sales guy did take it off me and try , I watched him try and press the home button about 5 times without success lol. Hopefully just a bad handset and nobody else gets this.
Mine worked great until I put a glass screen protector on it. Now I am having the issues you mentioned. Isn't there a way to recalibrate the touch screen sensitivity?
The occurrence with screen protectors, specially tempered glass protectors, is pretty common with these new curved phone screens because the glass has adhesive on the edges only, and the screen protector does not transmit positive contact to the phone screen on a consistent basis. The solution seems to be to use a protector with full screen adhesive, (LOCA), but it does need to be cured. Additionally, this method prevents another nuisance... the constant intrusion of dust and lint between the phone screen and the screen protector.

Very common with the glass screen protectors. Lots of information in the accessories forum.
Seems to be a quality control issue with lg. When i first bought my phone from a Sprint store, I noticed the same issues you mentioned. Had a spot on the screen that would only respond to short touches. If you moved an app to a certain spot on the home screen you couldn't move it, only open it. Exchanged it the next day in store. The replacement device works great with no issues but upon opening the box i noticed black plastic shavings underneath the plastic screen protector that wraps around the phone.

S9+ oleophobic coating wearing off

I bought my S9+ (SM-G9650 DS) back in April 2018 but these days I've noticed 3 lines that disappear when you clean the screen with microfiber cloth but reappears with my oil skin or water. I've read that it was the oleophobic coating also some guy on Reddit got his device fixed and a Samsung employee told him that it was a defective batch https://www.reddit.com/r/GalaxyS9/comments/8g534o/oleophobic_coating_wearing_off/
I hope Samsung Ecuador replace my screen or give me an replacement.

Try bringing it to an authorized service center. Had a local unit in Philippines have this same issue and they offered to replace the screen and battery.
Two months and 3 weeks with the GS9 + and I'm seeing oleophobic coating wearing off on the spots where thumb is used for scrolling. Not directly visible for now but when applying some drops of water and spreading on the screen can easily show where its wearing off.

Its a problem out here. Service center guys will replace the screen after keeping the phone with them for 1, 2 days but in the process they end up damaging/scratching the phone and then its a never ending process of follow ups . It happened so with my old galaxy s6 edge plus.

I don't have this issue over the main screen (yet) after about the same duration of use as you, but I've noticed it similar to this user here:
https://www.youtube.com/watch?v=qtDf53wcgmc
I certainly don't have it as bad as him and he also seems to demonstrate it over the main screen, rather than just the sides and the top left. I definitely have it over both the sides (around the curved edges) and the very top left area. What I'm curious about is whether I had it from the very start (you won't notice it until you "dirty" the screen a bit and have the right lighting and viewing conditions) as I don't think it's worsened since I first noticed it 2-3 weeks ago. However, it seems there are more reports of people noticing it get worse, which is not a good.
Do you think this is definitely a new thing or could it have been there from the start?
This is without a screen protector? Scary
Mmmm. I have had this problem with every samsung phone since the note 5, gs7 edge, gs8, gs8 plus, note 8. Now the gs9 plus . I notice it happens if use alcohol base products like hand sanitizer, etc and then use ur phone the OC starts to waredown. My gs9 plus looks really bad in sunlight cause of this reason. The only way to realive this problem would be to hide it with a water base screen protector or whitedome tempered glass.

I've never used any liquids on the screen aside from a bit of water.

I've owned every Galaxy S series smartphone in the past and each one suffered from this oleophobic coating getting removed exactly where the fingers constantly touch(especially the thumb) without the use of any alcohol or any other solution whatsoever and as I never used screen protectors. But S9 plus took the shortest time amongst them if I remember correctly and since currently its not visible yet from any direction or lighting condition without pouring water there, I ended up installing a tempered glass.
I've noticed this in two spots on my Galaxy S9+. A vertical streak in the upper left corner and a vertical streak on the middle-right.
They're not near the rounded part of the edge. They're not where my fingers reach. I think it was always like that but I only noticed recently. And in the brighter summer sun, it's VERY noticeable now.
Not sure of the best way to get it replaced.
Bought it through T-Mobile. Do I take it to them to replace? UBreakIFix? Or any other Samsung authorized repair place like the specific Best Buy ones?

Can you show a pic ? Just asking.
..
Clearly feels like QC issues in your case. Rather ask for replacement than going for repairing and such.
Sure. It's not the easiest thing to photograph. You have to get the reflection just right. But you can see here when I smear my palm across the upper corner and the sides, there's a toothpick-sized streak that doesn't get any fingerprints on it. And in the bright sunlight it's really noticeable.

Yeah its seen clearly. You should Ask T-Mobile for a replacement I would say,
Sorry for late reply but I got my phone repaired for free at Samsung Customer Service, if you also have problems with your oleophobic coating go inmediately and they should give you a new device or at least a screen replacement.
In my case the receptionist didn't understand what the oleophobic coating was and she said that my phone doesn't have any issues so you should try to convince her/him by using a flashlight to highlight the lines/smudges on the screen are still there even after they cleaned it with a microfiber cloth.
I received the phone after 4 days and they had also changed the battery and the buttons without any extra charge.
PD: English isn't my main language so feel free to correct my grammar if I've made any mistake or you doesn't understand me.

Hi what's the process? How much did it cost you? Mine has streaks on it. Looks like a tree branch. Thanks in advance
If they consider it as a manufacturing error, the repair will be free of course. Otherwise, screen replacement is around 200€.
