Screen protectors prevent cracks in your electronic devices, but if you apply them incorrectly or if your screen is not completely smooth, you can get air bubbles underneath. Once you have applied the screen protector, it will be difficult to remove the air bubbles unless you remove and reattach the screen protector. If you have air bubbles on the edges of your screen, you can easily remove them with oil.
Method 1 of 2: Reapply the screen protector
Step 1. Lift one corner of your screen protector with a razor blade to remove it easily
Carefully slide the sharp edge of a razor blade under one of the corners of your screen protector. Keep the blade horizontal so you don't accidentally scratch your screen. Once you lift the corner of your screen protector, it will slowly detach from your device. Remove the screen protector from your device as soon as the adhesive from the protector comes off.
- Do not try to bend the screen protector as this may break the protector.
- Many screen protectors can be removed and reapplied multiple times.
Step 2. Clean and dry your screen with a lint-free cloth
Dust particles on your screen are the most common reason for air bubbles under your screen protector. Wet the corner of a cloth with rubbing alcohol and wipe your screen with it to remove all the dust. After the wet cloth, use a lint-free cloth to dry your screen thoroughly.
You can also use individually wrapped wet wipes suitable for cleaning screens. These wipes are available in electronics stores
Work in a dust-free room. If you have air conditioning, turn it off first to avoid a lot of dust swirling around.
Step 3. Remove the last bits of fabric with masking tape
Stick a strip of tape on your screen and press it down gently so that it sticks. Carefully peel off the tape to remove smaller dust particles from the screen. Repeat this over the entire screen. Leave a small overlap on the area you've already cleaned so you don't miss any spots.
Cover your screen completely with tape if you want to clean everything at once
Step 4. Reapply the screen protector
Make sure the corners of your screen protector are flush with those of your mobile device so that the protector won't sit skewed on your screen. Place one corner of the protector against your display and gently press it into place once you are happy with the position of the screen protector. The adhesive on the back of the screen protector immediately sticks to the display.
Apply the screen protector to your screen in a damp room, such as a bathroom. This reduces the risk of air bubbles
Step 5. Rub your finger or a credit card over the surface of your screen protector
Once the screen protector is stuck to your display, place your finger or the corner of a credit card in the center of the screen. Push from the center of the screen to the corners to remove air bubbles from under your screen protector. Do this over the entire screen until you have removed all air bubbles.
Reapply the screen protector or consider getting a new screen protector if there are still air bubbles under your screen protector after these steps
Method 2 of 2: Remove air bubbles on the edges with oil
Step 1. Wet the end of a cotton swab with oil
Use olive oil or vegetable oil for best results. Pour 1–2 tsp (5–10 ml) of the oil into a small bowl so that you can easily dip the end of a cotton swab in the oil. Cover the cotton swab with a thin layer of the oil, but not so much that it drips off.
Step 2. Rub the swab against the edge with the air bubble
Shake off any excess oil from your cotton swab and work around the edges of your screen protector. Apply a thin layer of oil to the edges so that it can get under your screen protector. The oil removes the air bubbles and thus ensures a perfect seal.
If applying the oil doesn't remove the air bubbles, try gently lifting the corner of your screen protector with your fingernail or a razor blade to make it easier for the oil to get under the surface.
Step 3. Push the screen protector back into place and remove the residual oil
If your screen protector doesn't have air bubbles on the edges of the screen, push it firmly against the screen so that it sticks properly. Use a paper towel to dry the edges of the screen protector and remove any residual oil.
