The tempered glass screen protector often comes off due to wrong installation and irregular cleaning. There are also other reasons. Here you will learn main reasons why the protective glass on your iPhone keep coming off and how you can fix it.

Reason #1: Not enough cleaning of the phone screen before applying the screen protector

Before installing the tempered glass screen protector, you need to thoroughly clean your phone’s screen. Dust, debris, sweat or oil from your fingers prevent the screen protector from connecting securely to the screen, causing the tempered glass to come off. Some air bubbles will appear when the screen is not completely cleaned. And air gaps appear on the edges of the glass where dust and other debris gets in. Therefore, it is necessary to remove the air bubbles and debris under the tempered glass screen protector.

Do the following steps:

  1. Wipe the tempered glass screen protector with a wet or alcohol wipe. This will help remove debris and dirt on the glass.
  2. Then gently remove the screen protector and place it on a clean, flat surface with the sticky side facing up.
  3. Clean your phone screen. To clean the screen it is better to use wipes with 70% alcohol content. Pick up any moisture residue with a dry wipe.
  4. You need to remove debris and dirt from the sticky side of the tempered glass screen protector. Use Guide Stickers or sticky tape to clean the glass. Also use stickers or adhesive tape to attach the tempered glass screen protector.
  5. Install the tempered glass when the sticky side is clean. Before installing, check the phone screen. There should be no dust or dirt on the phone screen.

Reason #2: Dust and debris around the tempered glass screen protector

Debris and dust collects around the tempered glass screen protector if you don’t clean the phone screen for a long time. Dust and sand get stuck under the screen protector and damage the sticky layer that holds it to the phone’s screen, causing the screen protector to come off. Therefore, it is important to clean the protective glass regularly, at least 2-3 times a week.

Do the following steps:

  1. If necessary remove the case from the phone.
  2. Clean the tempered glass screen protector. Use a wet or alcohol wipe. You can also use a cleaner for TVs and PC screens.
  3. It is important to remove all dust and debris from around the edges of the tempered glass screen protector.
  4. If you can’t get the dust off with a wipe, then use an antistatic brush. You can use a clean, medium-hard toothbrush.
  5. If the dirt gets too deep under the glass, then use the previous solution. Remove the tempered glass screen protector to clean the iPhone screen and the sticky side of the screen protector.

Reason #3: If there is a bump on the tempered glass screen protector or a manufacturing defect

Due to manufacturing defects, the screen protector may not work as it should, which can cause the screen protector to peel off. The problem is found in cheap tempered glass screen protectors and knockoffs of well-known brands. Often the tempered glass screen protector is smaller in size. For this reason, dust and debris can get under the glass more quickly. It is advisable to replace the defective screen protector. Use the proven brands ZAGG, Belkin or OtterBox.

Reason #4: Scratches and cracks in the phone screen

Deep cracks and scratches on the phone screen can also be the reason why the screen protector keep coming off. The sticky layer of protective glass does not have enough fixation in the place of a chipped or cracked screen. Therefore, it is necessary to fix the screen protector with UV glue.

Do the following steps:

  1. Purchase UV glue to fix the screen protector. You will also need a UV lamp to dry the glue.
  2. Remove the old screen protector glass.
  3. Thoroughly clean the phone’s screen. Optionally, clean the sticky side of the screen protector.
  4. Apply UV glue to the center of the phone screen.
  5. Install the glass. Under the weight of the tempered glass, the UV glue will fill the free space evenly.
  6. Secure the protective glass. Use a tissue paper to wipe off any remaining UV glue.
  7. Use the UV lamp and heat the screen evenly for 2-3 minutes.
  8. When the glue hardens, the screen protector will be firmly attached to the phone screen. When you need to replace the tempered glass, heat the screen with a hair dryer and then lift and remove the protective glass.
