The easiest way to add extra safety to your iPhone, Android, or other electronic device is to use a screen protector. This protects your device screen from damage such as scratches and cracks. By following a few simple steps, you'll be able to install your screen protector perfectly and without any air bubbles. This wikiHow will show you how to apply a screen protector to your electronic device with and without an applicator.

Things You Should Know

Screens can be easily damaged from falls and regular use.
Use a screen protector to increase your device's safety and longevity.
When applying your screen protector, wash your hands and clean your station before proceeding.

1
Get a screen protector. They typically come custom-cut. (In a pinch, see the "Tips" to cut one down to fit.) There are a few basic materials: ^{[1]

- Semi-hard, slick, clear soda-bottle style such as PET, the most common and generally best. (Gimmicky variations such as semi-reflective or matte can be fun, but less practical.)
- Very hard, clear tempered glass, like a stronger microscope coverslip. Should have a plastic layer to hold together if damaged. Extremely scratch resistant, but brittle; tends to flake apart progressively once chipped.
- Very tough, thick plastic such as polycarbonate. Provides direct impact protection. Not very scratch resistant--won't stay pretty. May reduce accuracy of touchscreens.
- Soft vinyl plastic. Not recommended as generally less pleasant to use, but does prevent scratches.
2
Understand the limitations of a screen protector. Screen protectors mostly ward off light cosmetic scrapes and scratches, not breakage--a particular danger for fancy cell phones with their all glass fronts and often minimal plastic edge cushioning. A "bumper" case that wraps around the front edge of a phone can provide fairly effective yet stylish impact protection. Keep it out of back pockets and other crush danger areas.
- Ideal protection means getting a screen protector and a good case; a screen protector or case should ideally break and need replacement while protecting your phone from drops.

Anywhere indoors with calm air is a good start. You can improve things with steam. Running a hot shower works well, which fills the room with steam. When the steam has subsided, there will be less dust in the air than usual. This is the best time to apply the screen protector.
Dry them with a clean towel. Shake off any excessive lint.
5
Clean the screen. Wipe it with a mild solvent like eyeglass cleaner or rubbing alcohol--or a damp soapy rag, which would not risk damage to low quality surrounding finishes. Rub it dry with a soft cloth and remove as much lint as possible with a blower or by wiping lightly with a lint free cloth, such as the microfiber wipe often provided with the screen protector.
- If you are replacing an old screen protector, you may need to clean the glue residue .
6
Check placement of the screen protector. Carefully remove it from its box or packaging.Before you lift its backing, position the screen protector over the screen to see how much margin to leave on each side and ensure clearance of features such as camera spots (with which the screen protector's less even surface would interfere) and microphone holes.
- Avoid cutting glass screen protectors . You should purchase a screen protector that is the correct size of your device.
- Some screen protector kits include guide stickers. Without removing the backing, place the screen protector as if to install. Use the guide stickers to create a hinge on one side for easy application.
- Alternatively, you can stick a piece of tape on the top side of the screen protector (non-sticky side) to make it easier to place.
7
Remove residual bits of dust with a mild adhesive. Dust is the most important thing to remove from under a screen protector: bubbles will eventually diffuse out through the plastic and tiny finger marks will probably merge with the glue, but dust specks stay. Lightly dab a sticky note (such as a "Post-it") all over the screen. Looking at the reflection of a bright area in the screen at an angle will confirm the presence or absence of dust. Quickly attach the screen protector before dust can gather!
- Some screen protector kits include a special sticker to pick up dust.
- Make sure you look at the screen at an angle to make sure there is no dust on the screen.
8
Stick on the screen protector, aligning an edge carefully. Peel back the screen protector's backing from one end (leaving it on the other allows more control by holding that end). Align it with the correct edge of the screen, leaving the margin you determined previously and watching how the alignment of the sides perpendicular to it will fall. Then peel off the entire backing and smooth down the protector.
- Avoid touching the sticky part of the screen protector. Handle it like you would CDs (i.e. without touching the bottom).
- Keep the sticky side of the screen protector facing down once you peel off the backing. Dust is less likely to get stuck when you're applying it.
Little mistakes like tiny dust specks should be ignored, as trying to fix them will do more harm than good, the screen protector will soon absorb worse damage exactly as intended, and it will eventually be replaced for a fresh one. If you need to reposition the screen protector, lift an edge carefully with a thin but not sharp implement like a piece of backing material, fingernail, or plastic spoon edge. If a big speck of dust is underneath, try fishing for it with a sticky note, length of cellophane style tape (such as "Scotch") or sticky note, taking care not to disturb the adhesive.
Remove air bubbles. Wipe the air bubbles toward the edges with a smooth implement like a credit card. ^{[2]

Enjoy your gadget without fear.

The applicator is built into the packaging.
Make sure that it fits, or exchange for a different screen protector size. ^{[3]

It depends on the case. If your case obstructs the screen, you will need to remove the case before installing. If your screen protector is able to lay flat against your screen with the case on, you will be able to install it. You may have issues lining the screen protector correctly if the case is bulky.

Guide stickers create a hinge to place your new screen protector properly. Without removing the backing, place the screen protector on your screen. Place the guide stickers on one edge of the placed screen protector to create a secure hinge. Lift the screen protector from the non-hinge side and peel off the backing. Gently press the screen protector onto your screen. Squeegee any air bubbles. Remove the guide stickers.

Question

Is a glass screen protector better?

It depends on what is important to you. Glass protectors are typically tougher than plastic ones and will feel smoother to the touch, more like your original screen, but be more expensive. On the other hand, glass protectors are thicker than plastic and you may not like the way it looks. Also, sometimes cheap glass screen protectors will have a poor coating, which means that it might not feel as smooth as your original screen, attract fingerprints or sometimes not register your touches correctly at times.

Apply the screen protector as slowly and carefully as possible. There's nothing worse than a shaking hand when doing this.

To make bubble removal quicker, you can use a drop of water treated to reduce surface tension. Use a teaspoon of rubbing alcohol and/or a drop of dish soap in ¼ cup of water (from which you would take a large drop). Use scarcely to avoid liquid inside your device. Once the screen protector is installed, let it dry for a few hours.

Thin plastic screen protectors can be easily custom-cut, preferably with a paper cutter, slightly undersize to prevent edge lifting, and approximating rounded corners. Hold them firmly and cut off enough the first time: trying to trim off little slivers tends to lead to flexing and uneven edges.

Do not get frustrated. Remember, a screen protector is a consumable item. It needs to be applied decently to protect the screen from far worse and it will eventually be replaced.
