How to Fix Hairline Cracks in Phone Screen

If you find yourself facing the frustrating issue of hairline cracks on your phone screen, don’t worry. There are a few methods you can try to fix them. However, please note that not all cracks or phones can be fixed using these methods. It’s important to approach these solutions with caution and carefully follow the instructions provided. In this article, we will explore some potential solutions for fixing hairline cracks in your phone screen.

Fix Hairline Cracks in Phone Screen

Hairline cracks on your phone screen can be a bothersome issue, affecting both the appearance and functionality of your device. Before you consider replacing your screen or getting a new phone, it’s worth trying some DIY methods to fix the cracks yourself. Here are four possible methods you can attempt.

Method 1: Using Packing Tape or Super Glue

One method to consider is using packing tape or super glue to seal the crack. This approach aims to prevent the crack from spreading further. However, it’s important to note that it may also impact the touch sensitivity or visibility of your screen. Before attempting this method, carefully clean the cracked area and apply the tape or super glue as directed. Refer to reliable sources¹ for detailed instructions on how to execute this method effectively.

Method 2: Applying Toothpaste

Another method involves applying toothpaste to the damaged area and gently massaging it in. The idea behind this method is that toothpaste may help fill in the crack, making it less noticeable. However, it’s crucial to be aware that toothpaste might leave a residue or damage the oleophobic coating on your screen. Before trying this method, research reliable sources⁴ for step-by-step instructions to ensure you perform it correctly.

Method 3: Using a Repair Kit

If you prefer a more specialized approach, using a repair kit specifically designed for phone screens can be an effective solution. These kits typically contain a special adhesive and a UV light to bond the crack and restore the screen’s strength. However, it’s worth noting that repair kits may be relatively expensive or difficult to find. To successfully utilize a repair kit, refer to reputable sources² for comprehensive instructions.

Method 4: Utilizing Polishing Compound

For those looking to minimize the visibility of the crack, using a polishing compound like diamond paste or household cleaners is worth considering. This method aims to smooth out the edges of the crack, making it less noticeable. However, it’s crucial to exercise caution as polishing compounds have the potential to remove protective coatings or further scratch your screen. Before proceeding, consult reliable sources³ for detailed instructions on how to use polishing compounds safely.


In conclusion, hairline cracks on phone screens can be frustrating, but there are methods you can try to fix them. From using packing tape or super glue to applying toothpaste, utilizing a repair kit, or utilizing a polishing compound, these methods offer potential solutions. However, it’s essential to exercise caution and follow instructions carefully to avoid further damage. If none of these methods work, it may be necessary to consider screen replacement or getting a new phone. Good luck with your screen repair endeavors!
