Oleophobic Coating Come Off? - Google Pixel 4 XL Questions & Answers

I apologize if this has been covered. I did a search, but did not come up with anything exact to my problem.
So, in the last couple weeks, all of a sudden my screen gets super smudgy all the time. I clean it, then hardly any time later it's back. This did not happen before. It would stay so clean, not now. Would this be caused by the coating coming off? I thought I saw something about the 4xl having this issue late last year.
LMK!

Yes.
Have you been sterilizing your phone with sanitizing wipes or cleaners? With the emphasis on keeping touch surfaces clean, those types of cleaners can remove the coating faster than normal.
Can always buy some Fusso oleophobic coating to reapply or start using cheap screen protectors that you can replace when you feel the smoothness is gone.

I may have used an alcohol wipe on it due to the CV. I should have realized that could do it. So, the Fusso stuff, will it make my screen 'like' new? Or would a better option be a replacement?

Fusso will be a close approximation of factory oleophobic coating, but it's not completely the same.
I usually just change out my screen protector once I've scratched it in a bad way. I drop my phone every now and then, so loss of oleophobic coating isn't a big deal to me.

[Q] Screensurface polished away of to much thumb usage?

After playing much hours N.O.V.A 3 on my Galaxy Note there is a strange screen damage in the "weapon steering area" from my thumb.
There are no scratches or anything else, but this area is not so slippery than before and smut is more visible. When the screen is completly cleaned you can see nothing, but when it is dirty, you can see this special area.
I have a picture with breath on the screen and there you can see the "thumb"-area as a black oval egg (approx. 2 cm x 1 cm).
Is it realy possible that the screensurface can be damaged by to much thumb using at the same place? I thought the Note has a special resistant screen material?
I can not find anyone in the internet with the same problem. I don't think that my thumb is so much special so it can damage glass.
Possibly contact Sammy, or if you say it's OK when completly clean, then clean it and invest in a protector, I've used one from day one, I do with all my devices, Gorilla glass or not.

Yes, i think Samsung will not change the screen for less (maybe warranty?)
So I have the choice: a new screen for 200,- Euros or a good protector for 10,- Euros.

Ok, try the following: turn off your note, take out battery. With a glass cleaning product (non abrasive) clean the whole glass surface. DON'T use liquid only apply it with a cloth. Let it dry out (if it's a good product there is no need) and check with the phone still off if you still have the mark.
If you have the mark there are two possibilities: The display area of the note sucks or with the heat from the friction you unglued the display. Either way if the above solution doesn't work and still have warranty get it to a samsung service as soon as possible..
This is very interesting and since you are the first i will monitor this closely.
Word of advice (i do it always): with touchscreens apply a screensaver, i only use the cheapest and change them as needed....... Forget the miracle glasses and treatments, forget the vids on youtube it will get damaged sooner or later.

This is normal, had this on my S2 also, its the oleophobic coating that comes off after few months of usage and even faster if you polish your screen very often as I do. I also have this on my screen, it is not as "slippery" as when it was new. You can prevent it only by not touching the screen, or getting a screen protector, which I do not like.
I was thinking about getting the Glas screen protector with oleophobic coating, but in the description it says the coating will last for about a month, so I learned to live with it.
EDIT: Just noticed the picture, the thing that is visible is probably something else, but it not being so slippery and the smudges more visible, is the oleophobic coating that is missing.
Now I have found many users with a Galaxy Nexus and problems with the oleophobic coating. It seems to be the same problem.
But Samsung changed the displays for less (warranty), so I will send my device to the next samsung service partner.
Yeah, the Gorilla glass might be very hard and wear resistant, but the oleophobic coating is just a very thin layer of... something...
It has to wear off at some point. The big question is if it is possible to reapply the oleophobic stuff by ourselves.

"Sorry, you [i.e. me] are limited to 8 thanks per day", anyway thanks, if you ever get it, please share the experience
mine had the same problem, but luckily it went away on its own

Well it's happened, I cracked the glass!

You wouldn't believe how it happened either. I was using my tie to quickly remove a smudge before showing it off to someone. My tie has a small pin on it. While wiping lightly with the tip of my tie, an edge of my decorative pin slide across where the glass meets the opening of the microphone area (bottom) caught and edge and cracked it right there. Ya I know, the odds of it catching right there! This happened in an aircraft up at altitude, my screen was still use-able. Once we descended though (pressure increased) 4 almost uniform cracks spread out in a 'V' from the center of the microphone area and now my screen is completely useless and can't unlock it or even power the damn thing off.
I am shocked that it took so little effort though to break this glass. I am thankful though that literally the day before I completed an entire backup to SD card via the included Sony backup/restore app.
Now what.
me too!
Yes same here, my back glass cracked...... Its was in my pocket then I pulled my phone out and put it on a leather couch, within seconds I heard a "Tick" I picked up my phone and the glass had cracked.
Hot in the pocket and cold leather couch made this glass crack. also happened to my wifes phone 20mins ago when she put it on the kitchen bench.... that's what made me write this to this thread.
Massive fault with this phone. Totally ruined the IP rating now which was the reason why I brought this phone. And there is no where selling replacements of glass yet.
Those stories are shocking and I really feel for you guys. I have my Z in a cheap plastic/rubber case and I pray it wont be so easy to crack.
Ouch.. I (literally) threw my friends Z on the floir and nothing happened to it, now I've seen this its kinda shocking...
Hit Thanks if I helped you out

Good news is Visa is replacing the phone for me :good: Bad news is I'm really worried about it happening again now that I've seen how easy it occurs.
Even if replacement screens became available in the future how would a replacement be possible without compromising the water proof design of the phone?

At least we can conclude now that it wasn't because we removed out anti shatter sheet, since you still have yours on.

It has nothing to do with the case, but with either pressure difference and/or the temperature changing rapidly.
You can get replacement glass at:

It is a bit expensive though

Thanks for the link, I'm surprised replacement parts are available so quickly but regarding the repair I'm inclined to think that opening this phone up would compromise it and never be water proof again.
So I got my new replacement today. I had done a FULL backup with the included backup/restore app to my SD card in the old phone. I placed into new phone and ran restore immediately after initial setup.
My question is, it seems like I got most of my stuff back, but I'm confused about a few things. My home screen and other pages are still stock, ie it did not reorganize my widgets and apps the way I had them and my google accounts were NOT added that I was syncing previously. I did get my apps, (in the app drawer) and my texts/contacts though.
Am I missing something?
Another cracked glass from my father this time, out of the pocket and onto the bedside table and "tick" glass crack!
really pissing me off! I convinced everyone in my family to get this phone cause I thought it was awesome, now we are all paying the price. And I feel responsible.
$100 for a replacement is not good enough, Sony should be sending replacements out for free! Please post if anyone finds replacement glass for a reasonable price ($40 or less)
Now that the glass cracking threads are popping up I want to remind that heat differences are deadly to Gorilla Glass.
It has happened on lots of devices, mostly aluminum builds, like the Transformer Prime TF201 http://crackformerprime.blogspot.se/
Had one, and well. It's a 4 RMA story, and I've discouraged all aluminum-built devices ever since.
Aluminum cools - Quad core CPU heats, and lots of interesting glass strain may occur. Having said that, I'm curious when the aluminum-unibody HTC One owners pick up on this.
I'll update my guide to urge people to apply any provided protective back/screen protectors (if) provided with the Xperia Z. It aids uniform heat dissipation across the glass, minimizing chances for cracks.

Official backup application does not backup account credentials, launcher layout, nor most system settings. Else it would be considered a security flaw.
To perform full system backups you need to root you phone, and use a real backup application like Titanium Backup
Thanks Supersaiyan.IV, I've just rooted and will back up this way from here on.
Guys with cracked glass are you using a screen protector? Ifso, with or w/o the anti shatter film? OR are you using the phone w/o a screen protector with or w/o the anti shatter film? Thanks!
Mine was stock, ie, no protectors, original anti shatter film left on.
India is a primarily hot country, so nothing's gonna happen due to temperature differences here.

I would! the anti shatter film scratches easily and once it's scratched you will have to remove it or live with the damage.
Also removing the anti shatter film removes the sony logo.

touch problem after removing shatter proof film

I bought xperia z1 two weeks ago.
Yesterday I removed the shatter proof film front and
back but now I have touch issues with the screen
sometimes not respond and always when touch
some point it touches it two or three times like
when iam browsing and want to go to the previous
page when back button touched it brings me to two
previous page.
Then I knew that the glass isn't oleophobic like the
shatter film.
What's the solution for me??!
Please reply

maybe theres still some hidden glue left on the screen give it a good clean
to make sure if theres glue left try to breath on it you'll see if theres odd shapes forming from the condensation i remember that it clearly showed the glue when i did on mine

I have the exact same problem after removing the anti shatter film.
Has anyone else noticed this? If yes did one of you put another third-party screen protector on your phone afterwards and did this solve the touch-problems ?
Greetz
the problem solved
I put screen protector and touching screen is now ooth and slippery
But it's shame to sony to make their phones not oleophobic screen and put cheap film on the phone that gets scratches easily??
Sony wake up how you didn't notice problem like this??! .
I have touch issues every now and then with the shatter proof film on...
Mostly on the lower half of the screen...
Edit= its scratched up too
And BTW does removing it increase the brightness and/or change the hue of the screen(like the yellow hue most ppl get)

I wonder why you remove asf.....
I'm also having these problems, I just removed ASF because it got some pretty nasty scratches from being in my pocket jeans with no other items (I'm still in shock at how easy it gets damaged). I'm also having issues primarily with the soft keys, it goes all crazy and recognizes multiple touches, seems that other parts of the screen are not affected (I tested this particular area of the screen in landscape mode and seems to have this problem in whatever the area is displaying). No oleophobic screen also noticeable, so my search begins for a good screen protector.
It looks quite amazing without the Sony logo though.

Scratchs? I also saw people doing this on Dell 40" LED Screen to improve image quality but you risk to damage the Phone or the Display so I don't know how much is it worth.

As the previous reply said, scratches are probably a good motivator. Sony won't replace the ASF film under warranty and since many people have it scratched, they are probably quite tempted to just remove it..

Not to mention the fact that at least according to Sony, the film is supposed to make the touchscreen more sensitive and accurate, and after removing it, it will be too late to put it back.

Because when I look at my screen in my "flagship" 2013 phone I don't like seeing scratches, what is the point in having a device with FullHd Triluminos display etc etc when I can't enjoy it because of Sony's poor quality ASF..personally I don't know how someone thought of this as a standard, but hey I'm no engineer. By the way I applied a screen protector and everything's back to normal.
I for my part removed the ASF because my phone fell around 30cm on the floor, so almost just tickled it, and took such nasty and heavy scratches from it that it was impossible to keep it that way. Also it had a lot of minor scratches from just keeping it in my pocket.
What I can confirm is, that the touch issues are especially in the lower part of the screen. Also it seems like this problem occurs more often if the phone is "cold", for example if I use it outside.
I hope that this will be fixed software-wise through firmware/app (by better calibrating or smth like that) or trough a 3rd party screen protector.
the winter solved the issue
I removed the screen protector but there's no issues with touch screen
I think the problem is only in summer or hot climate because fingers have alot of oil in this time
what!!

Wow what a strange solution..what made you remove it in the first place? Was there any other change in circumstances that could explain the fix? I'm really interested since the way you explained your problem in the first post was exactly my issue as soon as I removed the ASF.
I'm waiting on 4.3 to even consider removing the screen protector as it cost me a lot of trouble putting it without a single particle of dust/bubbles/alignment. Anyway I live in a place where there's no "winter", it's always hot in here.
Actually it happens more in winter for me... Maybe because of the static electricity I guess... And the Aluminum frame...
Since 4.3 update, touchscreen problem is worse, even with the screen protector it sometimes skips when trying to use Swype keyboard in all situations, with or without case, cold or hot weather, touching the aluminium frame or not..seems to have something to do with oily fingers. Still hoping that a firmware update may correct it.

I do not use swypette but same here, after update the touch screen is worse. I know the sensitivity or the respond of the touch can be modified but at the moment everybody have something else in mind than try to fix this.

Fingerprint smudge

Has anyone who plays a lot of games notice a smudge that just will not go away? I play injustice 2 a lot and 2 spots on screen where my thumbs are usually it looks like I have worn away a costing on the glass. I can buff with a cloth but you can still see them as you turn phone in right light. I'm not trying to be nitpicky but it's not even month old and paid slot of money. I'll try and post pics when I get home and have access to another camera

I play a lot of Real Racing 3 (1-2 hours a day sometimes less) I have not noticed any fingerprint smudges that would not wipe away. My recommendation would be to get Eye glass or lens cleaner and a microfiber cloth. Wipe it down and see if that helps.

They have been working great so far and I use them to wipe down everything with a screen. Just remember to wash them frequently as well. I just throw mine in the laundry and then hang dry them.

Maybe you somehow wear off oleophobic coating, some chemicals will do that either when somehow deposited from your fingers or when cleaning.

Either try Samsung service center to fix it, or try fix it yourself. I use screen protector, so never experience it myself and I don't see this being mentioned too often, so I wouldn't even begin to speculate why it happened to you.
cant seem to post images and links here, so please just add https:// to this "imgur.com/a/oLaeF"
i've also got one unit with "smudges" on it after having the phone for just 2 days. i had to argue yell and get mad at Samsung technician when they said it was "normal", and I wasn't covered by the 7 day replacement warranty. "smudges" aren't noticeable when screen is on, it's more visible in black screen/screen off. i had to get the screen dirty with my finger natural oil/dirt, to give emphasis on the "smudges". i also used my other phone's camera flash to make it more visible. i've also tried putting those oleophobic liquid protector but it didnt help at all. the pictures i posted were after i applied the liquid so you be the judge.
is "smudge" the right term? not sure bout calling it a stain too. coz it's more like oil... just like when you put a drop of oil on a paper towel.
I actually have that as well, mine is on the Volume button up area the size of "a index finger". While wiping with my microfiber cloth, everywhere is smooth except that part, when I wipe I don't wipe it hard at all since the day I got my hands on it. I believe it's a defect right out the box and I don't use any screen protector.
I just saw your image Pryor06 except mine is not noticeable both on and off screen but it can be felt when wiping. Any conclusion?
Have you guys tried washing it under water with soap?
i actually haven't noticed any difference in the "texture"(?) of the screen. all felt smooth except with the visuals/optics of the screen when screen is off/black. i was on the bus on my way back home when I noticed the smudges under the sunlight. I had no cleaning materials that time, so for the meantime I used a little of my saliva:angel: on one part of the screen's problem. The surrounding part got clean, except the part with the issue. After I got home, I used alcohol and wiped the phone clean, thoroughly but gently, before applying the oleophobic liquid protection. "Smudges" were also around the bottom left, bottom center, bottom right of the screen but not as worse. I thought the top middle part smudge was enough evidence for me to claim warranty.
Blecap, try using white light from a phone camera to check your screen. Not sure about SG, but if you could get it replaced for warranty then go for it. Otherwise, I think all Samsung Note 8 have Concierge service, wherein our phone's screen is under warranty for free replacement of screen+labor for 6 months from date of purchase.
I had to be careful in handling the phone since day 1, because I wasn't able to get a screen protection. It's hard to prove and claim warranty here in the Philippines. All Samsung have to say is it's the fault of consumers, or normal wear and tear, and customers don't have anymore options. I've experienced it first hand, remember the screen lifting/bubble on Samsung Note 5, I was one of the victim. They blamed me for moisture getting in to the phone when I swear I haven't dropped the phone in any liquid. That's why I didn't even want to risk washing the phone in soap and water even with the IP68 of Note 8. I don't want to give Samsung an excuse to blame me again.
I actually was having double thoughts if I would surrender my phone for replacement warranty. I believe it wasn't affecting the phone's performance, so I thought I should just suck it up and live with it. But no, call me nitpicky/demanding/hard to please, but I just had the phone for barely 2 days, and with a price tag of almost $1,000, I know we should fight for our rights and demand a quality product. From my research before getting the phone, the only issue I read was the screen "bleeding" on the sides. Maybe that's why I wasn't that too observant on the smudges when I was checking the phone before they release it to me.
I usually just lurk around forums, but I decided to make my account here to warn others that such issue exist. It's a beautiful and powerful phone I have to admit it, but buyers should we aware and check carefully before spending their hard earned money.
Very unlikely
I do not believe you can wear off the coating so easily. Heavy gamer here. Switched to the Note 8 recently but gamed hard on the S8+ as well for months before switching. This includes games that required swiping constantly. The screen on that S8+ is still pristine.

Best thing is to use a non-alcoholic wet wipe and clean the screen then use a clean microfiber cloth.

Week old A2 and scratched screen??

Hi there. A week ago I bought Xiaomi Mi A2. Now I noticed my screen is scratched! In center of screen I can see all the moves my fingers do (look at the photo). It doesnt come off, no matter what cloth I rub it. Isnt A2 supposed to have GG5?
https://imgur.com/a/KfH7ziy
Can someone relate to this problem?
THX
I understand how hairline scratch occurs, but this?
EDIT: After few minutes I dont thing its scratched. By the looks and feels on polished screen it looks like some kind of ,,glue" overfilled frome side of the screen and was wiped to the right. I never used any protector except the original sticker but I know the digitizer and glass is somehow glued together so some excess of this maybe. Will try to put protector on it, if it is still visible then RMA
scratched wouldn't be covered under any warranty.
i think these only use gg3
in original posters case the pictures just look like finger smudges to me in person i bet its different but if that does move about and shows up when screen is on it may be fault panel so return for replacement.
faults do happen the % is low but they still happen no one or company can stop this they do test units before shipping

in original posters case the pictures just look like finger smudges to me in person i bet its different but if that does move about and shows up when screen is on it may be fault panel so return for replacement.
faults do happen the % is low but they still happen no one or company can stop this they do test units before shipping

GG3 was more scratch resistant than the GG5 so A2 is more likely to use GG5. As for the OP, it's either glue as you said which you could remove with some rubbing alcohol. If that doesn't work, then it could probably be the Oleophobic coating which could be a manufacturing error or you had some type of chemical on your hands that messed it up.

Since I dont work or use any chemicals in my life other than basic detergent for dishes I doubt that. Anyway I tried cleaning it off with isopropyl alcohol and sticker-glue remover with no luck. The stains are permanent, invisible when screen on. I tried rubbing it with credit card slightly and I can clearly feel that it is on the surface of glass. If I completely polish the screen with glasses cloth, the stains disappear and reappear when I slide my fingers over the area and ,,grease" it a little.
Contacted the seller, returning phone and getting my money back since I am positive it is a manufacturing problem.

No it's just the oleophobic coating. This is normal for GG5

Well you're probably right. I had no idea something like this exists. Put that in Google and found many pictures of worn off coating even on Samsungs. But after a week? What a shame
BTW other than what Iwrote, there easnt any chemical on the screen
EDIT: eg this looks exactly like the thing on my phone: https://forums.windowscentral.com/attachments/nokia-lumia-930/86096d1414705779t-img_0535.jpg
