The oleophobic coating has a thickness of 1 nanometer and protects the smartphone from the influence of several factors at once. It does not allow oil, dirt, moisture to remain on the screen, makes swiping your finger on the screen pleasant and smooth, and prevents scratches and small scratches on the screen. The composition of such a coating includes silicone, alkylsilane, solvent.
To check if there is a protective coating on the screen of your smartphone, you need to do the following. Try putting the drops on the screen and see how they flow: when tilted, this should happen quickly and the drops should leave no traces. If the coating is of high quality, there should be no fingerprints on it. The same applies to water-based landmarks.
Over time, the oleophobic coating is erased from any phone. On average, this period ranges from two months to several years. But you can extend the life of such a coating. To do this, follow a few rules: first of all, do not wipe the screen with alcohol; carry the device in a separate pocket, where there are no keys, coins and other small items; buy a protective cover (the ideal option is a book cover).
There are ways to restore the protective coating of the screen. But in most cases they either don’t work at all or only give results for a short time. The only way that really works is to buy a quality coating and protective glass.
