Instructions: How to Fix Hairline Cracks in Phone Screen  

Step One: Locate the crack on the phone screen. Clean the screen with a clean, dry cloth. Make sure there is no dirt or dust on it before proceeding to step two.

Step Two: Clean your hands and the surface to which you’re applying pressure to avoid getting dirt or grease into any cracks in the glass.

Step Three: Apply gentle, even pressure with a dry cloth over the cracked area for five minutes. This will help solidify the hairline cracks so that they can’t spread further when using more force later on in this process.

Step Four: Put some adhesive tape (or glue) around one side of where you want it applied to make sure there are no air bubbles inside before pressing down firmly onto both sides of it with your fingers while holding them together for 30 seconds before removing your finger from either end of the crack line entirely. Ensure there is no tape or glue on the other side of where you applied it to avoid getting any in your phone.

Adhesive Tape

Step Five: Clean off any pieces of adhesive that came away from either end and put a thin layer of pressure-sensitive adhesive over the line, holding it down for five minutes before letting go and repeating this process at least three times (up to six) until there are only tiny bits left around the edges.

Step Six: Find a clean, dry cloth and use the toothpick or other small tools to remove any dirt around the hairline crack. Then take your glass cleaner and carefully wipe away all of the residues that are left behind.

Types of Cracks in Phone Screen

a) Scratches:

Scratches are the most common type of hairline cracks in phone screens. Scratches happen when your finger slides across a rough surface (e.g., desk, car door) or is scratched by something such as sandpaper.

b) Hairline Cracks:

A crack can show up on your iPhone’s touch screen if you drop it and land on one corner with some force; this may also cause an impact break, which occurs when drops hit in different places where the glass might be weaker than other spots (e.g., the corners). Hairline cracks often start from impurities within the glass, like dust particles that settle during production, but they’re not always visible until after hours of usage because they are so fine.

c) Full or Partial Shatters:

If the hairline cracks are full or partial shatters, then you might already have a big problem. When glass particles break off inside your phone, they can cause short circuits and lead to fire risks if not removed by an expert technician.

d) Puncture Damage: 

Puncture damage is when a hairline crack becomes too large, and it shatters. Puncture damage often occurs due to drops and might happen from something as innocuous as turning up the volume of your phone or pressing on one side for long periods of time.

Some Tips & Advice To Prevent Cracks is Phone Screen

  1. Use a soft cloth to wipe your screen clean and dry it off afterward. This will help prevent any dust or dirt from interfering with the adhesive on the phone’s case.
  2. Do not use pressure when tapping on the touchscreen; this can cause hairline cracks in your mobile device’s display, which are difficult to repair. Try using two fingers instead of one finger for typing since more space between each tap prevents putting too much pressure on the glass surface while typing.
  3. Keep an eye out for dropped phones! If you drop your phone once, the chances are that there is no damage at all – if you do it multiple times, then you may see some hairline cracks develop in your displays as well as other parts of your phone.
  4. Avoid pressing on the side of your device. If you do, it may cause hairline cracks to develop in that part of the phone’s screen as well.
  5. Use a glass protector whenever possible for added protection against damage from falls or scratches and cracks.
