Protect your smartphone display with "liquid glass": You need to know that
Protecting the smartphone display with liquid glass is a miracle cure: "Hard as ruby" or "Smartphone stays as new" - this is what the liquid glass manufacturers advertise. We explain whether liquid glass is a good alternative to the screen protector or not.
Liquid glass for the smartphone display: top or scrap?
- Liquid glass is said to protect against scratches and cracks. In addition, the manufacturers advertise that it should be antibacterial and water-repellent. Electric smog would also have been reduced by around 90 percent.
- The customer should rub the smartphone display with liquid glass, let it dry and the display would be invulnerable. "Hard as ruby" and "better color and photo quality" - according to the manufacturer.
- The liquid glass is available in small bottles and practical towels. Stiftung Warentest tested one and was not convinced at all ...
Liquid glass disappointed at Stiftung Warentest
- Stiftung Warentest has treated a smartphone display with the liquid glass cloth from Peach (17.95 euros).
- Included were three cloths for cleaning, sealing scratches and tears and then polishing the display.
- The test conclusion: the seal was not to be seen or felt. The image quality has not changed either. The display is still very susceptible to scratches - this was tested in the laboratory with coins and pointed metal.
- Scratches: Neither with the naked eye, nor under the microscope, there was a discernible difference between the display glass with liquid glass and without liquid glass.
Conclusion: liquid glass is not an alternative to screen protectors
- Most smartphone displays now have a particularly hard protective layer. In order to protect them even better from scratches, apparently no liquid glass helps.
- We therefore recommend that you continue to use good screen protectors.
- They offer effective protection against scratches because their thickness protects the display from direct effects.
- They also do not provide splinter protection for the display. At least minor impacts can cushion rubber protective covers.
