In the test, some Ulefone staff covered one Ulefone Vienna by protective case without oleophobic coating while another Vienna and a Future were naked. When they put some Cola on the naked display and tilt the phone, Cola roll down as a whole, while on the film, it flow down like streams with much residual. When they want to smeared the Cola over the oleophobic screens, they found that was impossible, as the cola goes along the tester’s finger. While on the film, smearing was quite easy.
At the end the test, both oleophobic phones were put into the testers pocket, and when they were brought out, the screen became super clean. for people who don’t like to use protective films or tempered glass, oleophobic coating will save them much time from cleaning.
