Why Is There Spreading Black Spot on Your Phone Screen? (4 Reasons)

When something goes wrong with our phones, it can be a major inconvenience. One issue that can cause significant concern is the appearance of a dark spot on the screen. Unfortunately, fixing this problem may not be easy, especially if the spot begins to spread. In order to address the issue, it’s important to first understand what might be causing it. Black spots on phone screens can stem from a variety of factors, and screens themselves can be made in substantially different ways, which can lead to unique problems. Even two identical phones can have black spots caused by completely different issues. Now, we will explore the most common causes of black spots on phone screens so that you can better understand what’s happening and what you can do to fix the problem.

#1 Dead Pixels

Have you ever noticed a dark spot on your phone screen, particularly a black spot in the corner of your phone? This is a common issue that many people face. One of the most common causes of this problem is dead pixels. Dead pixels are tiny black or colored dots that appear on the screen and do not change color or display any image. They occur when a pixel on the screen stops working, and this can happen due to a manufacturing defect or overuse of the phone.

When dead pixels appear on your phone screen, they can be annoying and distracting, especially if they are located in a prominent area such as the corner of the screen. You may notice them more when the screen is displaying a dark image, as the dead pixel will stand out against the dark background. Dead pixels are not repairable and require the replacement of the entire screen, which can be expensive.

To avoid dead pixels on your phone screen, it is essential to handle your phone with care and avoid dropping it. Additionally, it’s best to avoid exposing your phone to extreme temperatures or humidity, as this can cause damage to the screen. If you notice a dead pixel on your screen, it’s best to get it repaired as soon as possible to prevent further damage to the screen.

A black spot in the corner of your phone or a dark spot on the phone screen can be caused by dead pixels. Dead pixels are a common issue that can occur due to manufacturing defects or overuse of the phone. They are not repairable and require the replacement of the entire screen, which can be expensive.

#2 Stuck Pixels

Another possible reason for the spreading black spot on your phone screen could be stuck pixels. Stuck pixels are a type of dead pixel that appear as small dots on the screen that are stuck in one color, often appearing as black dots. Unlike dead pixels, which don’t light up at all, stuck pixels can be more noticeable because they remain lit up even when they should be displaying a different color.

Stuck pixels can be caused by manufacturing defects, physical damage, or simply normal wear and tear on your device over time. If you notice a black spot on your phone screen that seems to be spreading or growing in size, it could be a sign of a stuck pixel. You may also notice other stuck pixels appearing in different areas of the screen, which can be especially frustrating if they’re located in prominent places like the center of the screen or near the edge.

Fortunately, there are some ways to fix stuck pixels, although they may not always work. One method involves using software or apps designed to help fix stuck pixels by displaying a rapidly changing pattern of colors on the affected area of the screen. Another method involves gently massaging the affected area with a soft cloth or applying pressure with a stuck pixel fixer tool. However, if the stuck pixel is caused by physical damage to the screen, it may not be fixable and you may need to have the screen replaced.

#3 Pressure

Black spots on phone screen can also be caused by pressure. If you apply too much pressure on the screen of your phone, it can cause small areas of the display to become discolored or have black spots. This can happen if you accidentally sit on your phone, drop a heavy object on it, or place it in your back pocket and sit down. It’s important to be careful with your phone and handle it gently to avoid any pressure on the screen.

If you notice a black spot on your mobile screen, you can try pressing on it gently with a soft cloth or tissue. Sometimes, applying pressure can help to fix the problem. However, be careful not to press too hard, as this can cause further damage to the screen.

In some cases, pressure can also cause cracks or fractures on the screen, which can lead to more severe problems like touch sensitivity issues and further discoloration. If the pressure has caused significant damage, it may be necessary to replace the screen or even the entire phone.

To prevent pressure-related black spots on your phone screen, it’s important to handle your phone with care. Avoid sitting on your phone or placing it in your back pocket when sitting down. Invest in a protective phone case and screen protector to help absorb any impact or pressure that your phone may experience. Taking these simple steps can go a long way in preventing black spots on your phone screen caused by pressure.

#4 LCD Components

LCD components can also contribute to the appearance of black spots on your phone screen. The LCD (liquid crystal display) is composed of several layers of components, including a backlight, polarizing filters, and the liquid crystal itself. If any of these components are damaged or malfunctioning, it can lead to the appearance of black spots on your phone screen.

For example, if the backlight has failed or is damaged, it can cause dark spots on the screen. Similarly, if the polarizing filters are damaged, it can cause discoloration or black spots on the screen. Another potential issue could be a malfunctioning liquid crystal layer, which can also result in black spots or patches.

If you suspect that your phone’s LCD components may be the cause of the black spots on your screen, it’s best to bring it to a professional repair service. They can diagnose the issue and replace any damaged components to restore your phone’s display to its normal functioning state.

How Do You Fix a Spreading Black Spot on Your Phone? (4 Ways)

After gaining an understanding of the factors behind the black spot on your phone and how it spreads, we can now examine potential solutions to tackle the issue. Given that the spot can emerge from various sources, the remedies will need to correspond to the root cause. Therefore, we will segment the approaches by cause and provide you with the most dependable choices for restoring your phone screen’s pristine appearance. In all scenarios, do-it-yourself (DIY) and professional repairs are feasible options.

#1 Repairing Stuck Pixels

If you’re dealing with a spreading black spot on your phone screen due to stuck pixels, there are several ways you can try to fix it. One of the most common methods is to use a pixel fixing software. There are many of these available online, both for desktop and mobile devices. These programs work by rapidly flashing different colors on your screen to try to unstick the problematic pixel. While this method isn’t guaranteed to work, it’s certainly worth a try and is often successful in fixing the issue.

Another method to try is massaging the area of the screen where the stuck pixel is located. Gently apply pressure with your finger or a soft cloth, being careful not to press too hard and damage the screen. This can sometimes dislodge the stuck pixel and get it functioning normally again.

If neither of these methods work, you may need to resort to a more invasive option, such as using a screen repair kit. These kits usually include a suction cup to remove the screen, a replacement LCD screen, and other tools needed for the repair. While this option may be more time-consuming and potentially costly, it’s often the only way to fix the issue if other methods fail.

#2 Relieving Pressure

Pressure Release

It is not uncommon for people to place their phone in their pocket, purse, or backpack and accidentally apply pressure to the screen, causing damage. Fortunately, relieving pressure is one way to fix a spreading black spot on your phone.

To relieve pressure, the first step is to remove your phone from the tight space it may be in. If it is in your pocket, take it out and place it in a safe and flat surface. Next, apply a small suction cup to the center of the black spot and gently lift it up. If you do not have a suction cup, you can use a piece of tape or sticky note to lift the spot up. Be sure to avoid using your fingers, as they may cause more damage to the screen.

Once the spot is lifted, you can try to gently massage the area around it. Use a soft microfiber cloth or a cotton swab to gently rub the screen in circular motions. This may help to distribute the pixels and reduce the appearance of the black spot. However, be careful not to apply too much pressure, as this could cause further damage.

In some cases, relieving pressure may not completely fix the black spot on your phone screen. If this is the case, you may need to seek professional help. A technician can determine the root cause of the problem and provide a more permanent solution.

#3 Dead Pixels

Repairing dead pixels on a phone screen can be a challenging task. In most cases, dead pixels cannot be repaired by software, and you will need to replace the damaged pixels to resolve the issue. While it’s technically possible to replace individual pixels, it’s not a practical solution on modern screens due to their tiny size. The tools and expertise required for pixel-level repairs are expensive and hard to find, making screen replacement a more viable option.

Fortunately, screen replacements are relatively affordable, and you can opt for a DIY screen replacement kit or take your phone to a repair shop for professional help. In most cases, the cost of replacing the screen is significantly less than that of replacing the entire phone, making it a cost-effective solution.

Replacing the screen eliminates the dead pixels, resolving the problem and restoring your phone’s functionality. If your phone is old and needs frequent repairs, it may be a good time to consider an upgrade to a newer model.

In summary, dead pixels on a phone screen require pixel-level repairs that are often not practical. Instead, screen replacement is a viable and cost-effective solution that eliminates the dead pixels and restores your phone’s functionality.

#4 Screen Damage

Display Damage

Spreading black spots on a phone screen are often a result of a cracked or damaged LCD tube. Even less common issues can lead to significant screen damage, and in such cases, a screen replacement is usually required. To make things easier, you should check all of your warranties to see if they cover any or all of the repair costs.

Accidental damage plans are specifically designed to cover issues like spreading black spots, so check if your phone has such coverage. Many screen protectors also offer warranty coverage, which can cover some or all of the repair expenses. Going through all of your potential warranties can help you save some money on the repair costs.

In summary, spreading black spots on a phone screen typically indicate a cracked or damaged LCD tube, and significant screen damage almost always requires a screen replacement. Checking your warranties, including accidental damage plans and screen protector warranties, can help cover some or all of the repair costs.

Why Does the Black Spot Spread on Your Phone Screen?

If you’ve noticed a black spot on your phone screen that seems to be spreading, you might be wondering what’s causing it. One of the most common reasons for a spreading black spot is physical damage to the screen, such as a crack or scratch. 

The damage can cause the LCD (liquid crystal display) layer to separate from the glass layer, allowing the liquid crystal to leak and spread across the screen. This liquid can cause the black spot to spread and become more visible over time.

Another possible cause of a spreading black spot is exposure to moisture. If your phone has been in contact with water or other liquids, it can damage the screen and cause the liquid crystal to spread. The moisture can also cause corrosion of the internal components, which can further damage the screen and lead to the spread of the black spot.

In some cases, a spreading black spot can also be caused by a faulty LCD panel or other hardware issues. These problems can cause the liquid crystal to leak and spread, even if the screen is not physically damaged or exposed to moisture.


A spreading black spot on phone screen is often caused by physical damage, exposure to moisture, or hardware issues. Understanding the root cause of the issue can help you determine the best course of action, whether it’s repairing or replacing the screen, or seeking professional assistance to address any internal hardware issues.
