Oleophobic coating peeling off - G 2014 General

Nano coating peeling off on my moto g 2014 after only 1 week, i have tested with a drop of water on the screen, in the middle where the nano coating has come off, the water leaves a trail, where the nano coating is still there, the wather goes right off without leaving a trail. You can see in the photos bellow...

Get some fusso which is expensive or put rain x on it. Bam. Done.

Friend, you reported this on Motorola's forum, and as the admin told you, this is NOT a "coating" peeling off - this is either grease or contamination.

Its actually oleophobic coating, i didn't clean the display with alcohol so don't really know how this happend, but its easy to fix. As @@rbiter said, rain x or screen protector

Screen Protector Reusable???

I had a Tilt and a screen protector that was just a plastic. It's reusable because I would just tuck the plastics into the edge of the screen.
Now, I got a Brando Screen Protector at home, which states reusable.
How are these washable/reusable screen protectors work with our phones? Is it pretty secure to wash and put it back on? I did it a lot with my tilt but I have no idea about the screen protectors regarding the Fuze.
currently I have a crappy one I bought from BestBuy and it is all scratched up, so thinking about switching to my Brando one.
Thanks in advance!

With most screen protectors you can wash them in light soapy water (maybe dip it in a cup with light soapy water). Shake the screen protector to shake off excess water, then use a blow drywer to dry off the rest of the water. You might have to do this a few times. You might catch some more dirt. (!)
Sometimes this works...sometimes it doesn't and you're just screwed and ending up having to buy another.
I've been using Martin Fields and haven't have a problem with washing them. You just need to be in an area that is dust free and clean.

How does it stay on your screen then if you wash it in water?
Doesn't the sticky part of the SP stop sticking?
No, actually it works really well just rinsing it under warm water (I didn't use any soap). I'd say 100% that it's definitely re-usable.
I was wiping fingerprints off mine on a wool blanket and a corner came up, half the screen protector came off, and the underside rubbed against the blanket, picking up a ton of dirt and fibers.
I took it off and rinsed it off pretty forcefully, and even used my fingernail to scrape the dirt and fibers off. When I was done it felt like the adhesive was mostly gone while damp but as it dried it was sticky again. I flicked off most of the water and put it on the freshly windexed phone (spray the towel once, not the phone!). There were still some tiny water droplets on the protector when I put it on but I gently squeezed them to the edge as I put it back on and they all squeezed out.
The protector still has a slightly mottled appearance which I figured was from scraping all the adhesive off in some areas but it turns out it's tiny amounts of moisture under the protector. Over the next 24 hours the mottled appearance dried and faded and the protector was like new again, 100% crystal clear. It even still great adhesive abilities even though I was literally scrapping at it under the warm water.
At the mall I notice the people that do the invisi-shield covers do it the basically the same way but use a hair drier to get rid of the mottled appearance quicker.
Bottom line. I scrubbed the protector pretty good because I thought it was a lost cause and afterward is was as good as new (better since it's on straight now with no edges to catch), so don't be too afraid to wash an re-use it if the underside gets dirty. Plus I make it sound like there is a risk of getting your phone wet but only if you drop it in the sink. The amount of water on the protector after flicking it few times is no more than if you get a few snowflakes on it and wipe them off with your hand.

Does the S4 Screen have Oleophobic coating?

I love the feel of the Gorilla glass 3 screen and it does not attract fingerprints easily. I just put on the Spigen Ultra crystal and it attracts finger prints. I know with Oleo coated screens the coating wears off after awhile and its no better then having a screen protector. If I know there is no coating that will wear off I may just go without the screen protector.
Thanks

I love it for the fact that it doesn't leave finger smudges...
I hate it for the fact that it's so slick that my phone sometimes detects a swipe when I am trying to select.

can you use this on screens that are not originally oleophobic?
This product looks pretty similar to rain-x in use. I don't know if anyone has tried that before on a screen, but it should have a similar effect. If I didn't use a screen protector, I would try it out. It makes my car windows super slick to the touch once applied.

Stay clear of Ghost Armor

Dear god what a frigging fiasco. Not only does every speck of dust adhere to the back of the screen protector, despite the application solution, but said dust particles seem to ave seriously deformed the plastic, so now the screen protector has zits.
Moving on to the entirely insufficient carbon fiber skin, there's not enough pieces to cover the sides, and the back piece is cut too small, always leaves a couple of millimeters of glass visible around the edge.
Moral:do NOT buy for the Xperia Z3!
I'm overnighting a new Skinomi setup....

Thats your opinion.
I have it as just a screen protector and it is fine. Much better than other protectors because with a case on it, it doesn't lift the screen protector edges.
The only issue I have with it is the screen oils up bad from fingerprints, easily fixed with one or two wipes over fabric
I guess this is an opinion too?
All that shows is you suck at applying screen protectors... lol.
You're supposed to install screen protectors in a dust free environment. Try turning the hot water on in the shower and waiting ~10 minutes, then try to install it.
Clearly you don't know very much.
Ghost Armor is the absolute worst of the wet-applied screen protectors. The whole idea behind wet-applied ones is so that the fluid captures the dust so it can be squeegied out from underneath the screen protector. Ghost Armor's adhesive, however, seems to grab onto every speck of dust it can find (apparently it's also got a static attraction component) and literally will not let go. Not even tape pulls it off, you have to soak it down and then scrape it off with a fingernail...at which point more dust gets pulled in and adheres. Any dust. Even in a humid bathroom. Horrible design.
Skinomi, Zagg, ArmorSuit, all of them work wonderfully in the same environment and under the same conditions. Ghost Armor? They can't even measure phone dimensions or create properly cut and sized skin pieces, so I guess asking them to create a proper wet-applied TPU screen protector is too much to ask.

I have used Ghost Armor many times, but have quit using wet-applied protectors in favor of glass protectors. (If I use one at all)
I guess your dust is more dusty than my dust.
I installed cheap mumbi display protectors on the front and back when i got the phone. Both without a single spot of dust or air under them. I don't even want to install my screen protector made of glass, as i then have to pull of the perfect installed normal protector.
Before installation, i had to wipe the screen several times as there was always new dust on it, i did not apply them wet or in my bathroom. Absolutely no problems, so i don't understand how there can be so much dust under the protector if anyone knows what he's doing.
Again, I can get any brand on completely dust-free, except for these things. Ergo, something is wrong with these things.

It's completely possible you had a bad install...
Perhaps they use a better adhesive. I've never had any problem installing Ghost Armor, or any other "brand" screen protector.

Maybe so. I think I read at one point that their protectors could optionally be installed dry, so maybe they're designed that way. But better isn't necessarily good. And I notice their instructions specify a wet install now.
Incidentally I just tried scraping off the dust and reapplying the thing. Only this time in my relatively dust free datacenter. And guess what? It managed to find some dust from somewhere. Damn, they should compete with Swiffer.
Anyway my emergency Skinomi will be here on Thursday. In the meantime this screen is driving me nuts though.

Interesting, I have used it on four phones, and not a single spec of dust on any of them if you prepare your surface correctly, I normally keep the phone screen facing the ground to stop dust settling on it, then apply holding the phone sideways as to keep as smallest surface area exposed to falling dust

ZF2 GorillaGlass3 protection is just a joke!!

My Z008 has got scratches out of nowhere. I always check before placing my phone under pant pockets. Still don't know how come these scratches are appearing. Now looking for a screen guard.
It's the gorilla glass 3 problem, I had the same scratches on my galaxy s5,so I got a tempered glass which is allot better in terms of micro scratches.
But fear not it's not the actual glass that is being scratched but the nano coating on top of the glass which is used to give a soft slide feeling, that's why you only see then with the screen off and from an angle.
The camera lens also gets scratched pretty easily, ad the glossy black plastic frame around the screen also develops small dents even if my phone is in a Ringke case.
I guess they really had to cut corners to give good specs at a cheap price.

Same here. the black bezel is easy scratched . I already have alot of scratches on my screen and almost 70 % on my camera lens. I only have my phone for 2 months . And got a case for it after 2 weeks.

With original zen cover no scratches, both zcreen and camera lens. Only a little scratch from wife's dimond earring near front cam, she forget to close cover before phone call, so for me filmscreen is waste of money and touch felling, useless
Apparently all material very soft. Frame around screen really soft.

I have had my phone since mid July and no scratches, black bezel around camera lens still perfect. Phone goes into my pocket every day. I use a dedicated pocket ie: nothing else goes in that pocket.
With the inexpensive Ringke case Impossible to scratch camera bezel or lens when placing phone on its back as it is then inset. For people that carry stuff in pocket with the phone I am sure a case would help prevent scratches. $200 or $300 for the phone spend $10.99 for a case. Lots of people must be buying the case as price has gone up several dollars since I got it.
Tempered Glass protector
If you all are experiencing these micro scratches, it's sort of an inevitable thing. Gorilla glass scratches with grains of sand or little things from your pocket. If you're really worried about your phone, you can purchase a tempered glass screen protector, and a case to fully protect your device!
Case and tempered glass screen protector are a must. Added them as soon as I took my zen out the box
Tempered glass save my screen from crack also.
Even glass broken, but my phone screen is protected.
I've had no issues other then dropping and breaking the screen but the repair guys told me this phone for the cost is really well built with easy repairability

I quit using a case months ago (cheap crappy pleather wallet case I bought for it just irritates me, and my wife pinched my clear soft gel case). No scratches on screen, one or two minor dents on the black plastic edges but you'd need a magnifying glass to notice them. Very pleased - my previous phone (black slate iPhone 5) got scratches on it if you as much as looked at it, and silver scratches on slate iodised aluminium looked bloody awful.
i have a cover and dont worry about scratch )
Yea same problem got alot of faint scratches out of nowhere threw a tempered glass on
Have quie a few phones and tablets, every one since the Samsung Galaxy S3 has had a tempered glass screen protector installed.
I know this phone is supposed to be cheap in comparison with say, the note 5, but I don't have around $500AUD to throw away just because I cracked the screen, even $200 to repair is a kick in the nuts....
Those glass protectors have helped a lot of my phones survive intact.
I don't care if I don't notice the scratches when the screen is on.
For those hoping miracles on gorilla glass:
Diamonds only can be scratched by diamonds
Sapphire only can be scratched by sapphire or diamonds
Gorrillaglass can be scratched by the diamonds, sapphire or whatever is harder than GorillaGlass, this is the rule.
Where you can find things harder than gorilla glass?
a Jewelry ? sure,
the floor? - maybe, some dirt particles actually are are sand, in some places sand is composed by limestone someties harder than gorillaglass.
your pockets? very likely specially if you have two cellphones, the sapphire cover on the lens camera easy can scratch the gorillaglass on other phone, also some pencils have diamond particles on its graphite, further DIAMONDS PARTICLES ARE VERY COMMON, SINCE SiNTETIC DIAMONDS ARE USE AS ABRASIVE ON MANY DRILLING TOOLS.
So, protect your gorillaglass if you hate scratches, harder is not warranty to be invulnerable.

Oleophobic Coating-Screen Looks Like Dogs Dinner

Hi folks,
I'm looking for feedback on oleophobic coating.
No matter whether it's the native glass or screen protectors, I just need to look at my phone and within seconds it's a mass of disgusting fingerprints.
Has anyone here any experience/recommendations of oleophobic products that actually work at keeping fingerprints at bay?
Your feedback would be much appreciated, even if it's only to confirm my thoughts that they're all just 'snake oil'.
Thanks.
I tried some products, and not a single one worked, I just accepted the fact, only way to reduce finger print smudges is to keep hands reasonably clean, cleanning the screen repeatedly or compulsively will at some point make micro scratches due to very tiny silica particles in the dust, this, I learned the hard way...
2 second wipe of my display and it's pristine again. Also, this is a Note device so I'm constantly using my S-Pen which helps lower the amount of fingerprint smudge.
I haven't touched the bare factory glass, so can't comment there. But the factory installed screen protector was very oleophobic in my experience. And my Whitestone Dome is almost impossible to leave fingerprints on it. Maybe you just have naturally greasy fingers?
Now the back glass? Ha! If I look at it, it gets a fingerprint mark.
Almost new
I bought my phone in early February. Removed the protective film early March, and 3 weeks later I can't hardly use fingerprint without wiping the screen thoroughly first.
The area where I swipe with my thumb is completely missing oleophobic coating.
I even bought my first leather case ever the day I removed the protective film.
Anyone know If Samsung has any warranty for that kind of stuff?

Doubtful IMHO because the screen works and detects your touch input. If your having to wipe it a lot before it will work then make sure your not smearing something onto the screen.
The oleophobic coating can wear off and from what I can interpret that's normal wear and tear (especially if your having to wipe the phone a lot) and not manufacturer defect. Granted it's always best to get a hold of Samsung yourself and ask them if it is covered under warranty... It may very well be, but only they will be able to tell you for sure with your phone.
Side note - If your trying to use the fingerprint sensor and can't without wiping the screen first then (based on your wording) your maybe doing it wrong. You don't swipe your finger on the sensor... You touch or tap your finger on the sensor. You can always also try deleting and re-registering your fingerprints using the instructions it provides, and also consider ensuring the phone firmware is up to date (in case any patches/fixes are included).
It's the oleophobic coating that has Weared out in that area.
If the screen is locked I unlock it with my fingerprint, and after that I swipe it open with my thumb.
And for some reason the oleophobic coating disappeared at that spot across the screen after a month's use.
So to be able to use my fingerprint, I have to clean the screen from the smear first.

My phone screen gets dirty and full of fingerprints. Despite that I have zero issues with the ultrasonic fingerprint detection.
Now if the screen gets extremely dirty thats a different matter... but I'm talking more then just a finger print or smudge of a finger print. I'm talking things like if I handle foods or materials (especially ones that leave sticky residue on the screen) that leaves a residue on the screen. This could cause me some issues, but that is understandablly normal and why I clean my phone once a week using a soft microfiber cloth.
I just wanted to throw this in even though I'm mad late, but I had my note10 replaced on warranty. I specifically stated that the oleophobic coating had worn out too soon and I believed it to be a defect. It's only been a few months since then and it's already worn out again. I'm gonna try a Whitestone Dome.
I'm using IQ Sheild. I wipe it down every now and then with a dry microfiber cloth, dampen slightly if needed.
Looks great at the 3 month mark with no scratches or mars.
It still retains its original surface feel/qualities.
If I need to replace it tomorrow I got my money's worth out of it. Very pleased with its performance.
After 10 months, I have zero scratches and the oleophobic coating still works, not as day one, but reasonably well, at least it is still very easy to clean after smudging appears, I kept the preimstalled film for three months, at that point, it was somewhat scratched, and made the screen look ugly, I peeled it off, and to this very day, I enjoy the naked display in its full glory

It will be fine until it faceplants on gravel etc or you get sand rubbing across it.
I live in the desert. It took only 6 months of no screen protector to get my S4 screen scratched even though I kepted it as clean as possible. Gorilla glass 6 is not more scratch than 4... the writings on the wall.
I did the S4 scratch test as an experiment as the LCD was already heat damaged.
The 10+ is always in a case with a screen protector and is spotless. I have zero issues with useablility or viewability and a high degree of necessary protection for a $1 G device.
Cleaning: best to a microfiber cloth to clean to glass or plastic. Ok to use dry, shake it out first even if just cleaned.
Use pure water for it's final rinse when washing.
I've used this method extensively on pro cam equipment including the plastic covered LCD displays without scratches. Always carefully clean off heavy debris like mud first though with running water.
Cloth, paper towels etc -will- scratch glass*, best not to use to clean optics with.
*only takes a grain or two of sand. Microfiber clothes help keep contaminants away from the item being cleaned very effectively.
I share with you the sand problem, as I live some 100 meters away the beach line, there is always wind blowing, and at some times, really strong gusts, not to mention when it is stormy, and yes, sand is a real nightmare
Yeah at least the 10 is well sealed... the older Notes weren't.

This doesn't surprise me.
Your dry fingers/palms are actually abrasive.
They can and do polish glass.
On large concave telescope mirrors they use the palm of their hands in the last phases of shaping it.
I've polished out very fine scratches on L glass lens coatings* using just a clean dry finger. It takes about half an hour.
*these optic coatings are hard and very thin. Without them the optics are degraded.
