Neither buying a mobile phone with software that pays particular attention to privacy, nor configuring permissions in an unhealthy way so that no one can access our phone. We get rid of problems for less than 10 euros with what seems to be the latest trend: covers that prevent the phone from seeing its contents, and even tempered glass.

The event has gone quite viral on social networks and although these caps and crystals have been on the market for a long time, they are not much known to the farthest user of the technological world.

There will be no one to look at your cell phone above 45 degrees

In the PC world, covers and filters have always been relatively popular. anti surveillance. This phenomenon is also present on mobile phones and is starting to gain popularity thanks to social networks. The concept is simple, put the cell phone in a box and make its panel invisible now as soon as there is a certain degree of inclination.

You can be even more cautious and bet on it. This is a tempered glass with filter. Thus, it is possible to use the mobile phone without a case, to open it, and not to be able to see its contents except for viewing angles.

How do these polarizing filters work? When we install this type of glass, we attach two small side-filtered tempered glass to the phone, although it is not visible to the naked eye. These narrow the viewing angle of the panel.From a lateral tilt of 30 degrees to the point where it becomes impossible to see its contents.

All light is still an electromagnetic wave oscillating in the direction of its axis. Polarizing filters act as a grid and if we have it vertically, blocking waves traveling in other directions. It’s basically the same filter technology used in photography to reduce reflections from certain surfaces.

with these filters only the person with the cell phone directly in front of you will see the screen.. If someone wants to look from behind or from the side, this will be difficult because with the minimum lateral angle the panel completely opaque.

Contraindication? The panel will lose a lot of brightness if we are not looking for something quality., as we find ourselves in front of a much darker glass than usual. For the rest, we mix the best of two worlds if we get a good one: privacy on the screen and additional physical protection on it.
