In this article, we will clearly explain the causes and prevention of cracked smartphone screens, as well as what to do if your smartphone screen does crack. We will also introduce NIMASO's recommended screen protectors and silicone cases, so please use this as a reference to extend the life of your smartphone!
The main causes of cracked smartphone screens
There are several common reasons why your phone screen may crack. Below we've listed the top 5 reasons:
Impact from a fall
Dropping your phone is the most common way that a screen can crack, and if it falls onto a hard surface, the impact can easily shatter the screen.

Pressure damage
If you put your phone in your pocket or bag, pressure can cause the screen to crack, especially if the phone is placed next to other hard objects.
Use of inappropriate protective films or cases
It is common to use screen protectors and cases to protect your smartphone screen, but using poor quality ones can have the opposite effect. If you don't choose the right protective gear, your screen will not provide enough protection against impacts.
Cracks due to temperature changes
Sudden changes in temperature can also cause your phone screen to crack. For example, if you suddenly go from a cold outside environment to a warm indoor environment, your phone screen may crack.
Manufacturing defects
Some smartphones have screens that are prone to cracking due to manufacturing defects. This is difficult to prevent because it is often not known at the time of purchase, but it can be replaced or repaired if it is within the warranty period.
Next, we'll explain why you shouldn't continue using a phone with a cracked screen.
What happens if you continue to use a smartphone with a cracked screen?
Continuing to use a smartphone with a cracked screen is not only a cosmetic problem, but also involves various risks. Here, we will explain in detail the eight dangers that may occur if you continue to use a smartphone with a cracked screen.

Finger injury
You could cut your fingers on shards of broken glass, and if your screen has fine cracks in it, you run the risk of injury every time you touch it.
Reduced visibility
A cracked screen can make it difficult to see what is displayed on the screen. Cracks can obstruct your view and make text and images hard to read.
Touch operation issues
A cracked screen can affect the touch sensor, making it difficult to operate the phone.
Water and moisture intrusion
Water or moisture can get in through a cracked screen and damage the internal electronic components, increasing the risk of your phone breaking down.
Battery problems
If the cracked screen causes internal damage, it can cause the battery to malfunction, resulting in poor battery life or, in the worst case scenario, the battery may expand or explode.
Warranty and Repair Issues
Continuing to use your phone with a cracked screen may void your warranty, and may even cause further internal damage that could result in more expensive repairs.
Data loss
As the internal damage progresses, your smartphone may suddenly break down and you may lose important data. Especially if you have not made a backup, there is a risk that you will not be able to recover your important information.
Risk of infection
Bacteria and viruses can easily adhere to a cracked screen, and if you then touch your hands or face with it, the risk of infection increases, posing a major hygiene problem.
Continuing to use a smartphone with a cracked screen carries these risks, so it is important to consider repairing or replacing it as soon as possible. Below are some ways to fix a cracked screen.
What to do if your smartphone screen is cracked?
If your smartphone screen is cracked, don't panic! Here are some specific methods to deal with a cracked screen.

Fix it yourself
If you have the technical skills, you may be able to carry out the repairs yourself.
Do not touch the screen
It is important not to carelessly touch a broken screen. Glass fragments can cause injury, so first protect the screen.
Apply protective film
To temporarily protect a cracked screen, it is effective to apply a screen protector, which will prevent the crack from spreading and reduce the risk of cutting your fingers.
Use a temporary repair kit
You can temporarily repair a cracked screen with a quick-fix kit available from the store, which contains liquid glass or special adhesives that can help make the crack less noticeable.
Back up your data
Continuing to use a smartphone with a cracked screen is risky, so we recommend that you immediately back up any important data. Use cloud services or external storage to protect your data.
Use repair service
The best way to be sure is to use a professional repair service.
Consider having the item repaired at a specialist shop
After applying first aid, consider having the problem repaired at a specialist shop. Repairs by professional technicians are necessary to extend the life of your smartphone and ensure its safe use.
Check warranty service
Check the warranty service for your smartphone and, if applicable, request a repair or replacement. By applying for a warranty, you can reduce the cost of repairs.
By taking these emergency measures, you can minimize the risk of your smartphone screen cracking. Next, we will introduce some points to prevent your smartphone screen from cracking.
Buy a new smartphone
If the repair costs are too high, purchasing a new phone is also an option.
Considering older model smartphones
You can save money by buying an older model smartphone instead of the latest one.
Buy a used smartphone
By purchasing from a trusted second-hand smartphone store, you can get a smartphone at a relatively low price.
There are various ways to deal with a cracked smartphone screen. It is important to choose the best method depending on the situation and deal with it as quickly as possible.
How to prevent your smartphone screen from cracking
To prevent your smartphone screen from cracking, it is important to take small precautions in your daily life. Below, we will introduce some specific methods for protecting your smartphone screen.
Handle with care
- Treat your phone with care Treating your phone with care on a daily basis can help prevent your screen from cracking. When carrying it around, hold it firmly or put it in a safe place in your pocket or bag.
- When the machine is left in a fixed area , the machine is not opened in a fixed area, and the wind falls in a small area. It is possible to prevent accidents by simply evacuating the general public and using the radio.
Use in an appropriate environment
- Avoid harsh environments: Using your smartphone in extremely hot or cold places can have a negative effect on the screen. Be careful of sudden changes in temperature and try to use it in an appropriate environment.
- If your smartphone gets wet , it can cause internal damage and even a cracked screen. It's a good idea to use a waterproof case or avoid using it in humid places.
Check regularly
- Check the condition of your screen Check your screen regularly for small cracks and scratches. Early detection and treatment can help prevent cracks from spreading.
- Check the condition of your screen protector and case If your screen protector or case is worn out, don't forget to replace it. Worn screen protectors can no longer adequately protect your screen.
Protective film used
- Applying a tempered glass film Tempered glass film absorbs shocks on the screen and makes it less likely to break. It is also highly transparent and does not affect touch operation.
- Use a plastic film Plastic film is also an effective way to protect your screen. It is more flexible than tempered glass and can protect against minor impacts.
Use a phone case
- Choose a shock-resistant case . A shock-resistant case will absorb the shock if you drop your smartphone and prevent the screen from cracking. It is especially good to choose one that protects the corners.
- Use a flip cover case A flip cover case covers the entire screen, preventing it from hitting the ground directly if dropped. It also helps protect your privacy by blocking the screen from being seen.
Practicing these methods is an effective way to prevent your smartphone screen from cracking. With regular care and attention, your smartphone will last longer.

Frequently asked questions
1. Why does tempered glass film crack?
Tempered glass films are manufactured to give strength to the surface, and are more impact resistant than regular glass, but they can still break under certain conditions. For example, if a strong impact is applied, a heavy object is dropped, or the film is hit from a corner, the stress on the surface of the glass film is concentrated all at once, which causes the film to break.
2. Can I still use a broken tempered glass film?
Although you can continue to use a cracked tempered glass film, the safety and protective function may be compromised depending on the cracked area. Therefore, if the cracked area is large or the adhesiveness of the entire film is lost, we recommend that you consider replacing it.
3. When is the appropriate time to replace tempered glass film?
The recommended replacement interval for tempered glass film is generally every one to two years.
