Your smartphone is a valuable asset and it is valuable to you not only for the price but also for the uses. A mobile phone protective screen does not protect the smartphone from everything and is not unbreakable. But it will add a layer of protection for your phone. Also, the cost of repairing your smartphone screen is much higher than the cost of a screen protector. You can always afford to pay a small amount to protect your dear phone from external scratches and bumps.

Here’s what to know before buying a mobile protective screen.

Plastic vs tempered glass

Mainly, you will find two types of screen protectors: plastic film and tempered glass.

Plastic film protectors have been around for a long time now and you’ve probably seen them or applied them on your phone. They look like a small sheet of plastic. You need to stick them carefully, as they roll up easily. Plastic protectors are fairly inexpensive, and you’ll find a package of five for two dollars. That said, the plastic protectors aren’t too sturdy, so they won’t help in the event of a fall. They are decent for regular scratches, but tempered glass will be much more durable. The plastic film is available in two types: wet apply and dry apply. Wet application offers more resistance but after a while it will appear pitted, like an orange peel.

Tempered glass protectors have become more popular over the past couple of years, especially with a sharp drop in prices. Now you can find them for a very low price, which is a small investment to protect a phone worth hundreds of dollars. The tempered glass protectors offer better resistance to scratches and, most importantly, insulate the screen a little from falls. The tempered glass also more closely mimics the feel of your real screen, which makes it much more pleasant to use.

Of the two, it makes more sense to buy a tempered glass protector today. Spend just a few dollars more to get much more protection.

Nature of the display

In an effort to make their products aesthetically pleasing and comfortable in the hands, a huge group of smartphone makers now make their device screens curved at the edges. Curved displays are beautiful and will determine what type of screen protector you buy for your device.

Depending on the curvature of your phone’s edges, we recommend that you copy screen protectors with a ‘D’ attached to their names (i.e. 2D / 2.5D / 3D / 5D / 7D screen protectors) because they provide full screen coverage and reliable.

A regular flat-edged shield will not effectively protect your phone’s display if it has been attached to a curved-edged display. There will be open spaces (called Halo Effect) that will trap dust, debris, small rocks that could ruin the phone screen.

What is 9H hardness? What really matters?

Once you start buying the protective screen online, you will see some specifications appear. Things like 9H hardness, military grade protection, oleophobic nano-coating and so on. Here’s a quick review of what they mean and what really matters.

Hardness 9H: Contrary to popular opinion, this is not a Mohs hardness test measure. 9H Hardness refers to the screen not being scratched by a 9H pencil, the hardest of all standard pencils. To be sure, it’s not a great test, but it’s a decent yardstick for finding out if the manufacturer cares enough to test the protector. Oleophobic Nano-Coating: This is the only specification you should be looking for, to be honest. Unlike plastic film protectors, tempered glass retains fingerprints. An oleophobic coating repels oil, which basically means that fingerprints won’t stick. A swipe with a microfiber cloth will eliminate them.

Military-grade protection: You’ll often find it advertised, but it’s a gimmick. The robustness of the screen protector will not always prevent the screen from cracking on the impact of a fall.

Privacy level: Apparently, reducing the viewing angles of a screen is now a “feature”, as the people next to you can’t read it. Don’t fall in love with this, folks.

Matte Display: Ah, the good old matte vs. gloss display. Depending on the type of screen you prefer, choose the protection. Matte protectors aren’t as common as glossy ones, but they’re available for most popular phones.

The bottom line is that choosing the right protector can be a long search, but it’s worth it once you find the right one.

Transparent or anti-reflective?

This is another decision you should make when purchasing a protective screen. From the name, the clear screen protectors are made with thin layers of clear materials. They are primarily evenly textured, offer a crystal clear view of your device’s display, and are nearly invisible when applied.

The anti-reflective protective screen, on the other hand, is translucent and “black” in color. This is because it is made of thin layers of unique films that reduce the bright, blinding light emitted by phones and ultimately reduce eye fatigue. This type of protectors are also opaque (not smooth) on the surface to protect against scratches and prevent fingerprints.

The clear protectors are easy to use both indoors and outdoors, but do not block UV rays or reduce glare. The glare shields, on the other hand, are perfect for outdoor use and people with visual impairments. The type of screen protector you buy should depend on where you would use your smartphone the most and how well your eyes are receptive to light.


Before getting the protective screen, make sure what kind of coverage your device will offer. There are two main types of coverage:

Full coverage: una protezione per lo schermo offre una copertura completa quando copre l’intero frontale del dispositivo in uno stile da bordo a bordo che diventa difficile dire se c’è una protezione per lo schermo sul dispositivo o meno.

Partial coverage: here the screen protector covers only the main area of the display (i.e. the screen itself) and leaves out the edges / bezels. This type of cover not only provides partial protection (the edges of the phone could break easily if dropped), but also makes the device lose some visual appeal
