Some methods to repair a cracked phone screen include car scratch remover, toothpaste and DIY home repair kits. These solutions can fix a range of screen damage, from tiny scratches to major cracking.
Polishes typically intended to remove scratches from cars, including Turtle Wax and 3M Scratch Remover, can also be used to buff a cracked smartphone screen. While this method can be effective for removing minor cracks and scratches, it should not be used on smartphones with oleophobic coatings, such as the iPhone 5. Users should also seal up the ports and buttons of their phones to ensure none of the solution gets in.
Toothpaste is another inexpensive remedy for a cracked or scratched phone screen. Simply apply a bit of paste to a cloth or cotton swab, rub the screen in a circular motion and then wash it with a damp cloth. Its important to use actual paste, not gel-based products.
For screens that are irreparably cracked, a DIY home repair kit is often the best solution. Websites such as Mission Repair and iFixit offer phone screen replacement kits that are typically cheaper than replacing a phone entirely. While these kits come with instructions, its also useful to consult online tutorial videos for more complete instructions on screen replacement.
