Macworld UK shows you how to apply a screen protector to iPhone or iPad.

The iPad and the iPhone both have glass screens. These are great to look at, and solid in construction. But the one issue we have with the design and build of all iDevices is that as beautiful as they look straight out-of-the-box they are prone top pick up scratches and dints. This is especially annoying on the display. When you are on the train watching The Sopranos in HD, no-on wants a bit scratch across Tony's head.

One way to prevent your screen getting scratched is to add a screen protector. There are caveats: a poorly applied screen protector film will leave bubbles or kinks on your screen surface. You really don't want to dumb down your beautiful iPhone or iPad in that way.  

But it's worth investing a few pounds in a screen protector to keep your phone in pristine condition, as long as you apply it correctly. Here's how to apply a screen protector to your iPhone or iPad.

In the video above from our colleagues at we're using a Tech21 Impact Shield on the iPad mini. This is easy to apply and doesn't affect image quality or touch sensitivity. However, the same technique outlined below applies to most screen protectors on all iPad and iPhone models. See also: iPad mini 2 preview: What can we expect from the next iPad mini?

How to use a screen protector to protect your iPhone- or iPad's screen

iPhone screenStep 1: Remove any existing screen protector, case or cover from your iPhone or iPad.

Step 2: Using a cloth included with your screen protector (or any microfibre cloth) carefully clean the iPhone or iPad screen. Ensure you remove all grime, fingerprints and dust particles. And check for existing scratches - if your screen is particularly scratched already a screen protector may make the issue worse.

Step 3: Remove the screen protector from its bag and peel off the backing. Be careful not to touch the back side of the protector as this will leave fingerprints and possibly dust stuck to it. Like a sticking plaster, it's critical the sticky bit remains clean.

Step 4: Pinching the protector between your fingers at the edges, align it with the edges of your screen, making sure the button and any other cutouts line up properly.

Step 5: With the protector squeezed so it touches only along a line in the middle of your iPad- or iPhone's screen, slowly press it into place. If you attempt to apply the protector flat to the whole screen, you'll end up with bubbles.

Step 6: If there are any small bubbles, use the included card (or a credit card) to firmly squeeze them towards the edges. Any tiny air pockets should disappear within a day or so.

Step 7: Remove the front film from the screen protector. Your iPhone or iPad is now fully protected!
