The screen of any phone, if you hold it in your hands for even a few minutes, quickly becomes covered with greasy stains. In such cases, wipe the display or don’t wipe it, the old stains still remain, and new ones appear. To remove marks, microfiber cloths are most often used, which do not quickly get rid of fingerprints; conventional cleaning products often cannot be used either. An oleophobic coating for any smartphone will help reduce the scale of the problem; it helps get rid of stains; all you need to do is swipe a napkin across the screen once.
History of creation
Oleophobic coating was invented and patented in 2005 by scientists from Germany.
The patent was filed by ]Apple[/anchor], interested in an improved coating.
The same company began to use this coating in its phones - for the first time in the 3GS model. Later, other manufacturers of mobile gadgets began to use the oleophobic coating.
In some cases, the oleophobic coating is not used on the screen directly, but on a film that is glued to the screen of the gadget.
Today, most tablets and smartphones in the mid-price category and above use an oleophobic coating.
Even when replacing an iPad and iPhone display without such a coating, authorized service centers install screens with an oleophobic coating.
Why do you need an oleophobic coating?
Why do you need an oleophobic coating?
The coating is not able to completely protect the gadget's display from damage and scratches.
However, it can protect against dust, dirt and fingerprints. A display with such a coating gets dirty less often, and the dirt itself is easier to remove.
For some manufacturers, an oleophobic coating can prevent glare from the sun.
Of course, it is impossible to completely protect yourself from the sun's rays, but more comfortable use in daylight with such a screen is ensured.
Take a large photo of your fingerprint
As far as I know, this is impossible. Capacitive screens (those that detect your thumb) are not sensitive enough to pick up a fingerprint. Cool idea though.
Perhaps consider using a camera (although it should be of fairly high quality).
I can offer you one alternative, not a fingerprint. There are several apps developed on android that basically recognize your pressure and not your fingerprint and it reminds you that they are taking your fingerprint.
First, don't ask for a code. How to prevent fingerprints from being recognized? This place is not to give out code, but a snippet or help.
You're asking someone to post complex code here. that's funny. Secondly, if a library for FingerPrint recognition was available. I highly doubt you can do anything about it. Why? I need to do a large fingerprint in an android app. When the user presses their thumb on the pad screen, their thumb shows me that I need to get a JPEG image.
Please does anyone know a repeat.
How to find out if your device has an oleophobic coating
There is an oleophobic coating on the right, but not on the left.
It’s easy to check whether the display has an oleophobic coating.
All you have to do is take water into a pipette and drop it onto the screen. After this, tilt the gadget slightly so that the drop rolls down the screen.
If a drop of water leaves a mark and wets the screen, then there is no oleophobic coating on the smartphone or tablet.
However, be careful: when checking the screen, make sure that water does not penetrate into the holes on the gadget (for example, on the buttons, or on the speaker, headphone or charging jacks).
You can see how the presence of an oleophobic coating is checked in this video:
Stay incognito
The web browser on your phone, like your computer, offers an incognito or private mode to limit data. When you open a session in this mode, the application will forget the pages you visited and the keywords you searched for as soon as you close the window.
However, private browsing does not make you invisible. For example, if you log into Facebook in incognito mode, the social network will record your activity. Your Internet Service Provider (ISP) may also log your online behavior. To hide your activity from him, you will need to rely on a Network (VPN).
The process of using private mode will depend on the browser you prefer. For example, to launch incognito mode in Chrome , click on the menu button (three dots) in the upper right corner of the page and select “New incognito tab” .
If you forgot to use incognito mode, you can still clear your saved data. Just click “Menu” - “Settings” - “Privacy” - “Clear browsing data” .
For iPhone users using Safari, tap the Show Pages (two squares) in the bottom right corner of the screen and select Private .
Now, when you press the "+" to open a new tab, it will be in incognito mode. To clear data collected outside of private mode, open Settings and select Safari - Clear History and Website Data .
How long will the oleophobic coating last?
The oleophobic layer is applied to the screen using vapor deposition.
After a certain time, this layer wears off because it is very thin. The service life of the oleophobic coating depends on the conditions of use of the device and the intensity of use.
On the first models of devices with a similar coating, wiping of the layer in place of the unlock slider could be noticed after just a few months.
Some gadget owners noted wiping areas in areas of frequent clicks and swipes.
Sometimes the coating would disappear where the device came into contact with a case, items in a bag, or rough clothing (such as the seams of jeans).
Today, manufacturers have improved the oleophobic coating, so it is almost impossible to detect the wiping of the layer or its wear.
In practice, the oleophobic layer wears out in 6-12 months.
How to clean a smartphone screen: list of things and materials
Paper towel
They can be used to wipe the kitchen table or other utensils, or use them for your hands, but not for your phone display. After wiping the screen with paper towels, lint and fibers remain on the case, spoiling the appearance of the device. Also, paper towels can completely scratch the screen.
Window cleaning liquid
Your phone screen is made of glass, but that doesn't mean window cleaner will work on your display. Many smartphones are equipped with a protective coating that is corroded by chemicals.
Other household chemicals
For example, chemicals for cleaning bathrooms, kitchens, tiles and other household products are contraindicated for use on a smartphone. They also break down the oleophobic coating of the display. In its instructions, Apple states that users should never clean the screen with household chemicals.
Makeup remover
Oddly enough, the display coating is more delicate (in terms of composition) than human skin. Most makeup removers contain substances that are unfavorable and aggressive for the screen (for example, alcohol). Such components will inevitably harm your smartphone.
Cloth
Most often, clothes are made from fairly rough materials. This is especially true for jeans. If you frequently wipe your phone with denim, you can easily scratch the display. Many people say: “Everyone does this,” and they do everything wrong. This method allows you to get rid of small stains and marks, that’s true. But do not forget that with each such wipe you damage the oleophobic coating of your smartphone.
Alcohol
Alcohol corrodes the protective shell of the screen, so after treating the surface of the smartphone with alcohol, you will only reduce the resistance of the display to scratches. Before purchasing display cleaning wipes, make sure they do not contain alcohol.
Compressed air
A smartphone is a fragile thing. Blowing through the device with compressed air may damage internal components. Google and Apple strongly discourage this cleaning method.
Acetic acid (vinegar)
You can safely use vinegar to wipe the phone case. But do not use this product to clean the display, glass surfaces of your smartphone, or camera lenses.
Disinfectant wipes
Wet (antibacterial) wipes do an excellent job of cleaning your hands from germs and dirt. Visually, they can also clean the display of your gadget. But with each “cleaning”, the wipes destroy the protective coating of the screen.
Soap
There is no clear answer as to whether this cleaning method can be used. Google notes that you can clean the display with soap, as long as the foam does not get into the case.
Hydrogen peroxide
Apple experts say that peroxide can damage the display surface. You should not experiment with this product and use it to clean smartphones.
Petrol
It's hard to imagine a user wiping a phone with gasoline, but still. If you are using this product, stop immediately. Gasoline can break down plastic, not to mention the fragile oleophobic coating on the display.

Oleophobic coating - protective films: which is better
The protective film also has an oleophobic layer
Good protective films and glasses also have an oleophobic layer.
To check whether your device has such a layer, it is not necessary to glue such protection to the display. To check, use plain water or a marker (water-based).
If an oleophobic coating is present, it will repel the layer applied by the marker and turn it into small drops.
Comparison of two protective coatings with and without an oleophobic layer in this video:
What can't you do?
Cleanliness is clean, but breaking the phone is definitely not part of the plan. When it comes to disinfecting your gadget, you need to keep the following points in mind.
- It is not recommended to spray anything on your phone or tablet, even liquid sanitizers.
- We do not recommend gel sanitizer. It may get inside the device.
- Washing in water is absurd. Otherwise, the sensitive “filling” will have a long life.
- Washing in soapy water is a fiasco. Even devices with IP68 protection are not designed for “chemicals” in water.
- It is better to forget about bleach-based products, they leave stains on the screen.
- It is forbidden to use any abrasive cleaning agents, as grains of sand will scratch the surface.
iPhone
Apple phones are powerful horses. However, like every purebred “horse”, they need special care. Apple equipment cannot be cleaned with a regular alcohol wipe or doused with gel sanitizer. The basic rules for cleaning an iPhone are below.
iPhone 11, iPhone 11 Pro Max
The body of the device itself is made of textured frosted glass. When used for a long time without cleaning, it can “transfer” dirt from objects in contact with the phone. However, there is no need to be afraid of this.
In most cases, dust is removed in a standard way, including on the iPhone 11 display. The screen will shine like new, and there will be no trace of obscenity left.
Important : To prevent the glass case from catching dirt, just hide it in a thin silicone case. It will not particularly affect the thickness, but the device itself will be cleaner + protected from damage.
Informative article: Which is better: iPhone or Samsung - which of the 2 smartphones to choose?
iPhone XS, iPhone X, iPhone 8, iPhone 7
These phones have a standard back:
- XS has metal + protective glass,
- Older models have only metal.
This makes them a little easier to clean.
If to wipe the X and XS you need to follow exactly the same instructions as above, then for the “old” iPhones it is slightly different:
- The metal back can be wiped with any napkin. He is not afraid of alcohol;
- The front end will have to be wiped more carefully - all because of the Home button, which can be “drowned” by too much liquid.
iPhone 6s, iPhone 6, iPhone 5s
Removing dirt and dust from these phones is practically no different from cleaning the iPhone 7. Except that you need to do it more carefully.
Mobile phones are not equipped with protection from moisture and dust, so even a drop falling under the case can break the device.

Is it worth gluing a protective film onto the “native” oleophobic coating?
Protective film for your phone
There are both “pros” and “cons”.
On the one hand, gluing films will allow you to “renew” the oleophobic coating, on the other hand, due to contact with the adhesive base of the protection, the “native” coating will begin to wear off.
Depending on the quality of the film or protective glass, 3-4 applications of such additional protection can completely destroy the factory oleophobic layer of your device.
K How to erase fingerprints
Fingerprints are patterns on the palms that are unique to each person. They are used by law enforcement agencies to identify criminals. Typically, traces left after touching have a sweat imprint. If you don’t want to leave traces, be it a mark on the mirror or signs of presence, you need to know that sweat includes fat and water.
To erase fingerprints, it is enough to have a cloth or napkin and a degreasing detergent with you.
Where there are traces of fingerprints, it is necessary to apply detergent. Next, you need to thoroughly wipe it and rinse with water. If fingerprints are not visible, but you need to find them, you need to have a special aerosol and a light source with you.
With glass everything is simpler, you just need to steam it and you're done. There is nothing complicated about how to find fingerprints if they are not visible
To find prints on porcelain or furniture, just point the light source at an angle and look closely at the item. If the surface is wet or there is dirt on it, you need to use an aerosol.
Just apply it and wait for the mixture to dry. Sometimes the question arises of how to get rid of fingerprints; there are several methods for this. The first is a surgical intervention, after which there will be no trace on the hands. But such operations are carried out only for law enforcement officers and are not carried out without compelling reasons.
To avoid problems with how to remove fingerprints, you should wear gloves before work or cover your hands with a viscous substance that will not allow the sweat glands to pass through.
Everyone has their own reasons for removing fingerprints. This may be a desire not to stain the item or to remain invisible. Before doing this, it is important to know how to find fingerprints and what needs to be done to remove them.

What the oleophobic coating doesn’t like
Friction is the main enemy of oleophobic coating
The main enemy of oleophobic coating is friction.
Even with normal taps on the screen, the layer is gradually destroyed.
But the greatest wear and tear occurs when the smartphone is carried in a pocket, or when it comes into contact with rough materials. Any fabrics, surfaces or hard objects slowly but surely destroy the oleophobic layer.
The oleophobic layer is quickly erased from contact with solvents, as well as products based on them.
Liquids with a high percentage of alcohol can destroy the layer. Rough napkins, paper and abrasive fabrics also have a bad effect on the oleophobic coating.
To preserve the oleophobic coating for a long time, carry your smartphone in a case that protects the display.
To wipe the screen, use only a soft microfiber cloth.
Do not use solvent-based cleaners or those containing more than 60% alcohol. Do not wipe the display with wet wipes, especially for car wipes.
Why should you disinfect your phone screen?
The smartphone must be periodically wiped clean from dirt.
During the epidemic, most people have become accustomed to constantly washing their hands and face to reduce the risk of contracting COVID-19.
Everything would be fine, but people often completely forget that smartphones, if not disinfected, can become a carrier of any infection.
On the street, in the store, in transport, we constantly use mobile phones. During a conversation, we pick up a smartphone. This leads to the fact that viruses and bacteria can accumulate on the screen and body of the device.
According to research by American scientists, one square centimeter of a mobile phone can contain up to 25 thousand bacteria. This is several times more than on a toilet seat. Therefore, it is simply necessary to process your smartphone.
How can you replace the “native” oleophobic coating?
How to replace the oleophobic layer
The most budget option is protective glass or film with an oleophobic layer.
First (before gluing), check for the presence of a repellent coating (read how to do this above), then carefully glue it onto the screen. As a result, you'll get a few extra months of good display protection from dirt and fingerprints.
In specialized stores there are many products that imitate oleophobic coating on the screen. P
They come in the form of sprays and are fairly easy to apply to the display. However, service center specialists do not recommend using such sprays, since their composition and, therefore, the likely consequences of use are unpredictable.
However, if you don’t mind experimenting with your gadget, you can, at your own peril and risk, use one of the “folk” methods of restoring the oleophobic coating:
How to clean protective glass?
If you need to remove scratches from the top of the protection, then polish the defects with felt, a soft cloth, or using auxiliary products - white toothpaste, GOI paste or olive oil. Another way to clean protective glass
on the inside is the use of water and soap.

Oleophobic coating: disadvantages and advantages
What are the advantages of oleophobic coating
Let’s name the main “advantages” of the oleophobic coating:
- no fingerprints;
- There will be no fingerprints from the attached ear on the smartphone after a conversation;
- pleasant tactile sensations (to the touch);
- less resistance when sliding your finger across the screen.
Among the disadvantages, the main one is the already mentioned fragility of the oleophobic coating.
Many users unreasonably believe that the coating will not wear out for a long time and will also reliably protect the device from liquids or grease.
Fingerprint scanner: security and bypass protection
Let's say you managed to fool the fingerprint sensor. What's next? iOS is a closed system, and all device memory will be encrypted. Options?
If we are talking about hacking Touch ID, then it is difficult to deceive the sensor, but it is possible. To fool modern sensors, you will have to create a three-dimensional model of your finger, and from the right material. On older devices (iPhone 5s, iPad mini 3), bypassing the sensor is much easier.
For example, a team of German hackers was able to scan the iPhone 5s sensor two days after the device went on the market by simply printing the original fingerprint at 2400 dpi.
Before the release of the sixth version of Android, manufacturers managed to release a ton of devices to which they had incorrectly attached fingerprint sensors. It’s not even interesting to break them, everything is so sad there. It is clear that Google could not tolerate this situation for long. They didn't. Two reference devices were released at once: Nexus 5X and Nexus 6P.
They include permanent encryption of the data section and the correct implementation of fingerprint sensors, called Nexus Imprint. Touch ID is a unique hardware and software complex, and the word “unique” does not carry an advertising connotation: each sensor is configured during the production process to work with specific device. Remember the “error 53” scandal? It was this feature that became a stumbling block that blocked the operation of devices with a fingerprint sensor replaced in makeshift conditions.
How to care for a screen with an oleophobic coating
How to care for such a screen?
You must follow these simple rules, and then the oleophobic coating on your device will last as long as possible.
What not to do:
- Do not wipe the screen with conventional cleaning products. These include household chemicals, alcohol-based solutions, and solvent-based liquids. These products will instantly cause chemical or mechanical damage to the oleophobic layer.
- Do not leave your mobile gadget exposed to ultraviolet rays. Direct sunlight can severely damage the protective film. After exposure to them, the display surface will lose its smoothness and become uneven.
- Direct mechanical impact should be avoided. Thus, an ordinary seam on a jeans pocket can cause scuffs on the device’s display. At a point of constant contact, the protective layer can thin out quite quickly.
How to keep your screen pristine
To do this, you should follow simple rules:
- Before using any device, be sure to cover the display with an additional protective layer.
- For game lovers and active smartphone users, experts advise applying impact-resistant film to the screen.
- Remove dirt using a microfiber cloth (either dry or soaked in a special solution).
How to save
Many people are interested in whether the oleophobic coating wears out, how quickly it wears off, and what to do if it wears off. The film is subject to abrasion over time, but not on all models and not always; most often this happens due to frequent touching of the display; the problem is common among gamers. Operation without a film or cover on the screen contributes to accelerated abrasion; constant contact of the device with fabric (if you put the phone in your pocket) also leads to a reduction in service life.
In addition to mechanical stress, the screen is exposed to chemical stress, this occurs due to the use of chemical cleaning agents. What should I do to prevent the oleophobic coating from quickly wearing off? In order to extend its service life, the device should not be left in direct sunlight, it is not recommended to wipe it with alcohol-containing products, and protective covers must be put on the gadget.
Experts do not recommend using household products for cleaning (for cleaning window glass, antibacterial solutions), since the oleophobic coating is erased and wears out faster in this case. Products for liquid crystal screens are also contraindicated in this case; they can damage the coating.
A regular microfiber cloth will help you quickly and effectively get rid of marks on the screen.
How to apply an oleophobic coating with your own hands
In service centers, the procedure for applying an oleophobic coating is not so cheap.
Of course, it is better to entrust this procedure to experienced specialists, but there is an alternative option: apply the coating yourself.
For those who like to experiment and who don’t mind their mobile devices, we offer one of the guides for applying an oleophobic coating to the display of a tablet or smartphone yourself.
First you need to buy an oleophobic coating in a specialized online store. The cover kit is called “Fusso SmartPhone”.
Step 1
Clearing the screen
The cover comes with a clean piece of microfiber cloth. Use it to thoroughly wipe the smartphone screen, being careful not to leave dust or fingerprints on the surface.
Step 2
Apply liquid
Now apply Fusso liquid to the display of your smartphone or tablet.
For a smartphone, 10-15 drops of liquid are enough. Now, using microfiber, quickly rub the liquid into the device screen, trying to distribute it evenly over the surface.
Tip: when applying liquid to the tablet screen, roughly divide the display area into several sections (4 or 8), then rub the liquid into the selected area of the screen (since “Fusso” dries quite quickly). The volume of liquid for each sector is the same as for the entire smartphone screen.
Step 3
Wipe off the liquid
You should repeat Step 2 two or three times.
Now leave the gadget alone for 6-8 hours, trying not to touch the display surface. During this time, the oleophobic layer should be tightly absorbed into the touch screen.
It is better to apply layers more than one day. Thanks to this, each subsequent layer of oleophobic coating is tightly “eaten” into the structure of the display. This improves its durability and performance.
It is better to apply layers more than one day. Thanks to this, each subsequent layer of oleophobic coating is tightly “eaten” into the structure of the display. This improves its durability and performance.
Limit app activity logging
Each of the apps on your phone will take a slightly different approach to logging your activity. Some of them allow you to avoid being tracked by using incognito mode, while others will stop tracking you if you make the appropriate settings.
For example, the Android version of YouTube (not yet available on iOS) has an incognito mode that doesn't track the videos you watch. To activate it, open the app, tap your avatar in the top right corner of the screen and select Turn on Incognito .
On the other hand, Google Maps will track your location by default, which allows you to accumulate a lot of data about your actual movements. To stop this, go to Settings : launch the app, tap the menu button (three dots) in the top left corner of the screen and tap Settings (on Android) or the gear icon (on iOS) . In settings, select “Personal content” and turn off the location history feature.
There are millions of apps on the market, with no strict rules for recording your behavior. But in general, a good first step is to check the above settings - incognito mode and do not track.
If you don't find these options, you will have to clear all activities manually. This process varies depending on the operating system.
On Android, open Settings - Apps & notifications , select an application from the list and click Storage - Clear storage . This will allow you to erase all data that the application stores locally. After this, the application will behave as if you installed it from scratch.
You won't find an identical option on iOS, but you can achieve the same effect by uninstalling and reinstalling the app. Open the Settings , tap General - iPhone Storage, and select one of the apps. Then click "Uninstall a program" (iPhone Storage) to erase all its data. After that, reinstall the application from the App Store.
This is not very practical to do for all your applications every day. But you can choose to do manual cleaning at regular intervals (say, once a month), before a trip, or whenever you want to start over.
