Review of Pixel 4
According to colleagues from Android Central,the extra oleophobic coating of the display starts to lose its qualities on some Pixel 4 devices, including the device that these guys have at their disposal. The problem began to appear within a few weeks after moderate use. By the way, Pixel 2 had a similar problem at the time. On some models, the Pixel 3 and Pixel 3 XL also.
What is the essence of the problem, let's figure it out…
Oleophobic coating — this is the layer thatmanufacturers add to most touchscreen devices. Its main purpose — Protects the screen from smudges and greasy fingerprints. Thanks to the presence of such a coating, you can use your phone all day long, touching it with naturally oily fingers. Such a coating is usually not applied to the back of smartphones with a glass body in order to comfortably hold the phone in the palm of your hand. But on screen this technology is quite common.
So, Pixel 4 begins to lose this over timeprotection. Apparently, the oleophobic coating on its display is not of adequate quality, as this problem begins to appear after only five weeks of use.
The solution in this case can only be consideredinstallation of a protective film made of high-quality tempered glass or its cheap version made of plastic. In both cases, they usually include oleophobic processing so that the screen does not look constantly dirty.
