Cracked Glass of a Mobile Phone: Unpleasant Situation that Can Be Prevented

The display of a mobile phone is, without a single doubt, one of the most important parts of a phone. But at the same time, it is one of the most fragile ones. Just a moment of inattention, your phone falls to the ground, and an annoying crack appears. Sometimes the crack doesn't affect the functionality, other times, though, the phone stops working. Replacing the display is not cheap. However, protecting your phone with adhesive foil or glass is significantly cheaper. There are many reasons that speak in favour of obtaining phone screen protection in the form of foil or glass:

  • Repairing or replacing the display is more expensive than protecting it with glass
  • During the repair, the user doesn't have a mobile phone and it is necessary to get a new phone temporarily
  • It is necessary to transfer data from one phone to another, which may not be easy with a broken display
  • A phone that is well cared for by the owner can be sold at a higher price

Foil or, even better, tempered glass is a simple and inexpensive way to protect your phone from damage. Moreover, you don't have to worry about not being able to stick the foil or glass on. The procedure is simple and can be found below for both protection options.

Easier Installation Using Adhesive Liquid and Special UV Light

Installation of screen protection doesn't necessarily have to be a nightmare and can be made easier. Foil in particular can be problematic due to air bubbles. The adhesive liquid will help here, its advantage is that it is possible to move the film, even if it has been already placed on the display. Once you are satisfied with the position of the film on the screen, simply push the liquid with a spatula from the center of the device to the edges directly into the cloth. You can also see it in the video below. You'll get the liquid, for example, with Screenshield film protectors.

Some brands have even more sophisticated system for applying the protective glass and films. Among such manufacturers is for example Whitestone Dome Glass. In addition to the adhesive liquid, they also use UV light to finish the process. It's an interesting and effective way to glue tempered glass. UV light comes from a special lamp, which can be bought as a part of the package or separately.

i You can install a ScreenShield film protector not only to your phone.

This causes the applied layer of liquid under the glass to harden due to the exposure of UV rays. This method is suitable for installation of the 3D glass, which is a glass that is curved at the sides exactly according to the curved edges of the phone. Such glass can thus completely protect the entire front side of the device.
