If you own an iPhone, from the X model to the latest iPhone 17 Pro Max, it's possible you've noticed spots on the screen that impair viewing and the user experience. These spots can arise for various reasons, affecting your phone's performance and aesthetics. At iServices, we understand the importance of a clean and functional screen, which is why we present a complete guide to help you understand the origin of this problem and how you can solve it.

Spots on the iPhone screen are not just a visual nuisance; they can indicate more serious problems that, if left untreated, could compromise the device's functionality. From hardware-related issues to damage caused by liquids or dirt, it is essential to identify the cause to apply the appropriate solution. In this article, we detail the most common causes, practical solutions, and when you should consult our specialized technicians.

Whatever your model, iPhone X, iPhone 11, iPhone 12, iPhone 13, iPhone 14, iPhone 15, or the brand new iPhone 17 Pro Max, our team is ready to help you resolve screen spots with the highest quality and warranty.

Causes of iPhone Screen Spots

Humidity or Liquid Damage

Exposure of the iPhone to humidity or liquids is one of the most frequent causes of screen spots. When water or another liquid penetrates the screen's interior, it can cause discoloration, whitish or yellow spots, and, in more severe cases, display failures.

Physical Screen Damage

Falls or impacts can cause internal screen damage, even if the outer glass appears intact. This damage includes spots caused by damaged liquid crystals, which manifest as dark or distorted areas on the screen.

Coloration Issues or Manufacturing Defect

In some cases, screen spots can result from manufacturing problems or defects related to the bonding of the screen panel. These defects can appear over time and are common in older models or after poorly executed repairs.

Dirt and Residues on the Screen Surface

Surface spots can also be caused by dirt, natural hand oils, or residues from inappropriate cleaning products. Although easier to remove, they can be mistaken for more serious internal spots.

Solutions Table

Cause	Recommended Solution	Complexity
Dirt and residues on the screen	Careful cleaning with specific products	Low
Coloration/manufacturing problems	Diagnosis and possible screen replacement	Medium
Humidity or liquid damage	Specialized drying and, if necessary, screen repair	High
Physical screen damage	Complete screen replacement	Very High

Step-by-Step Solutions

Careful Screen Cleaning

1. Turn off your phone to prevent any additional damage.
2. Use a clean, dry microfiber cloth to remove dust and dirt.
3. If necessary, apply a small amount of screen-specific cleaning product to the cloth (never directly to the screen).
4. Gently wipe in circular motions until surface spots are removed.
5. Turn on your phone and check if the spots have disappeared.

Why do spots appear on my iPhone screen even without falls or liquid contact?

Spots can arise due to internal defects, such as coloration problems or LCD panel failures, even without apparent external causes. They can also result from natural wear and tear or manufacturing imperfections, especially in older models.

Can I clean internal screen spots with household products?

No, internal spots cannot be removed with superficial cleaning. Household products can further damage the screen. For internal spots, it is ideal to seek specialized technical assistance for diagnosis and repair.

How long does screen repair for spots take at iServices?

At iServices, we offer express delivery, and in many cases, screen repair can be done on the same day, depending on the model and complexity. We recommend booking in advance to ensure immediate availability.

My iPhone has screen spots after a software update, what should I do?

Spots after software updates are rare and usually indicate a physical problem, not related to the software. We recommend turning off the device and performing a diagnosis with us to identify the real cause.
