Screen protectors are essential for safeguarding your phone's screen from scratches and cracks. However, they can sometimes start to peel or loosen at the corners, leaving your screen vulnerable to damage. If you're looking to reattach a plastic screen protector, you'll need to address the adhesive. While some suggest using superglue, this may not work on all surfaces, especially curved glass screens. Instead, consider using a hairdryer on a low setting to heat the corner of the screen protector for about 15 seconds, which should help reactivate the adhesive. You can then apply gentle pressure with a cleaning cloth to ensure the protector adheres to the screen. If this doesn't work, you may need to consider a new screen protector, being sure to follow the proper steps for application to avoid future peeling issues.

What You'll Learn
Use a hairdryer to loosen the adhesive
If you're looking to reattach your plastic screen protector, using a hairdryer is a great way to loosen the adhesive and get a smooth finish. Here's a detailed, step-by-step guide to help you through the process:
Prepare the Hairdryer
Firstly, ensure your hairdryer is set to a low heat setting. You don't want to risk damaging your phone by using excessive heat. Hold the hairdryer about 12 inches (300 mm) away from the screen.
Apply Heat
Now, gently apply heat to the screen protector with the hairdryer. Move the hairdryer back and forth for around 15 seconds to evenly distribute the heat. Don't hold the hairdryer in one spot for too long, and avoid pointing it directly at one area of the screen for an extended period.
Test and Adjust
After applying heat, test the corners of the screen protector to see if it's loosened. Gently pry at one corner with your fingernail or the corner of a credit card. If it doesn't lift easily, apply heat again for a few more seconds, then try the other corners until you find one that's loose enough to work with.
Loosen and Reattach
Once you've loosened a corner, continue using your fingernail or a toothpick to gently lift the screen protector. Work your way around the edges of the screen, loosening the protector as you go. Be careful not to rush, as you don't want to tear the screen protector. Once it's loosened to your satisfaction, you can reattach it by gently pressing it back into place, ensuring it's perfectly aligned.
Using a hairdryer to loosen the adhesive is an effective way to adjust and reattach your plastic screen protector. Remember to be gentle, work slowly, and avoid excessive heat to protect your phone and achieve a seamless finish.

Use a toothpick to pry up the corner
If your fingernails aren't doing the trick, try using a toothpick to pry up the corner of the screen protector. Make sure the sharp end of the toothpick is pointing up and away from the screen, so you don't damage it. Gently pry up one corner of the screen protector with the toothpick. If one corner isn't coming loose, try another.
Once a corner is loosened, use your fingers to gently pull it up and away from the phone. Begin peeling the protector up along the sides. Go slowly, as you don't want to rush the job and tear your screen protector into pieces.
Now, take a credit card and try sliding it under each corner of the screen protector. For this step, it's best to use an older credit card or something you don't mind getting messy with adhesive. Alternatively, you could use a guitar pick or a plectrum. Slide the card or tool of your choosing under each corner cautiously, taking care not to scratch the phone screen.
With a corner pulled up, push the tool left and right to encourage detachment. Push a credit card gently along the length of the display to remove the screen protector.

Clean the phone screen
To clean your phone screen before reattaching a plastic screen protector, you should first power off your device. This is an important step as it ensures you do not accidentally interact with the screen while cleaning it. Next, take a microfiber cloth and dampen it with water. You can also use a mild cleaning spray made for electronics or isopropyl alcohol. Make sure not to oversoak the cloth to avoid water damage.
Gently wipe down your phone screen with the damp cloth to remove any dust or dirt. Once you've wiped the screen, use a dry microfiber cloth to remove any remaining residue. If needed, air dry your phone before proceeding to reattach the screen protector.
It is important to clean your phone screen thoroughly to ensure no dust or dirt gets trapped under the screen protector. This can cause air bubbles and affect the adhesion of the protector to your screen. A clean screen also helps to maintain the overall hygiene of your device, especially considering the number of germs that can accumulate on phone screens.
In addition to cleaning the phone screen, it is also recommended to clean the work area where you will be reattaching the screen protector. This helps to prevent dust or dirt from getting onto the screen as you apply the protector.

Reapply the screen protector
Firstly, make sure you have a clean work area and a quiet space to concentrate. Once your workstation is ready, you'll want to loosen the adhesive on the screen protector. One of the most effective ways to do this is to use a hairdryer on its lowest heat setting and heat the protector for about 15 seconds. Gently lift the screen protector from each corner using your fingernail or a toothpick. Pull up gently from the corner and begin peeling the protector up along its sides.
Once the screen protector has been removed, set it aside on a clean surface with the sticky side up. Clean your phone's screen with a damp microfiber towel to prevent dust and remove any residue with a dry cloth. If your screen protector came with a special solution, spray it on the front and back of the screen protector to keep it moist during the installation process.
Now you're ready to reapply the screen protector. Ensure you line up your protector with your phone’s screen on all sides. Slowly and gently place the protector on the top of your clean screen, starting at one end and moving to the other. Once you’ve done that, firmly run your fingers over the adhesive to smooth out any bubbles, starting at the centre and pushing out towards the edges.
Note that the adhesive won't be as strong as the first time, so be firm and ensure you remove all air bubbles. Also, be aware that the screen protector will lose its stickiness if you try to reapply it too many times.

Remove air bubbles
Air bubbles can be a common issue when applying a new screen protector, but there are several methods to remove them. Firstly, it is important to ensure that your screen is clean and dust-free before applying the screen protector, as dust, lint, and oil from your fingertips can cause air bubbles to form. Use a microfiber cloth or cleaning kit to wipe away any dust particles, and avoid using tissues or paper towels as they can leave fibres behind.
If you notice air bubbles after applying the screen protector, you can try to remove them by using a plastic card or a thin object, such as a credit card, to lift the edge of the screen protector and slowly peel it back. Be careful not to crease or damage the protector. Once the protector is lifted, check the screen for any debris and remove it with adhesive tape. Then, realign and reapply the screen protector, pressing out any remaining air bubbles from the centre outward.
For stubborn air bubbles, gentle heat can be applied to soften the adhesive. Use a hair dryer on a low setting and hold it around 6 inches away from the screen, moving the nozzle to avoid keeping the heat in one spot for too long. After heating, use a plastic card to push the bubbles towards the edge of the screen.
Alternatively, if the air bubbles are near the edges of the screen protector, you may be able to massage them out with cooking oil. Simply apply a small amount of oil to the edge of the screen protector and use a paper towel to wipe off any excess.
To prevent air bubbles from forming in the first place, it is recommended to apply the screen protector in a dust-free environment, such as a room with less dust or a bathroom after running a hot shower to trap airborne dust particles.
