The iPhone screen is one of the most advanced elements of an Apple smartphone. It's bright, contrast-rich, has accurate color reproduction, and a high resolution. But even such technologically advanced displays can start to behave strangely over time: spots appear on the surface. spots, divorces, shadows or color changes.
Many users don't pay attention to this at first, but after a while, the stains become increasingly noticeable and interfere with the use of the device. Why this happens, can it be fixed, and where to go for a quality repair—we'll find out with experts. RudService.
Why are there spots on my iPhone screen?
Screen stains are a common problem among iPhone owners of various models, from older iPhone 6/7/8 models to the modern 13 and 15 Pro. Visually, this can look different:
-
light or yellow areas in the corners;
-
dark dots or stripes on the matrix;
-
rainbow streaks under glass;
-
areas with uneven illumination.
Here are the main reasons why this happens:
1. Pressure or mechanical action
The most common reason is mechanical damageEven if the glass is intact, the internal structure of the display (matrix or backlight) could have been damaged by impact or strong pressure.
This often happens when an iPhone is carried in a pocket with keys, placed face-down on a hard surface, or accidentally sat on. This results in uneven backlighting within the display, creating spots or "halos."
2. Moisture ingress
Even with water resistance (IP67, IP68), the iPhone is not completely sealed. Over time, the micro-gaskets lose elasticity, and water can get inside the case. condensate or moisture.
This causes whitish or green spots to appear, especially on light-colored screens. Moisture gradually destroys the backlight and screen cables, and without professional cleaning, the damage becomes irreversible.
3. Device overheating
If your iPhone is frequently used in a hot room, exposed to direct sunlight, or used for resource-intensive tasks (games, videos, navigation), the screen is prone to overheating.
From this the backlight layer is degrading or appear yellow areas In high-temperature areas. OLED displays may experience color distortion or pixel burn-in.
4. Manufacturing defect
Sometimes stains appear due to factory defect — especially on early batches of certain models. Such defects might not be noticeable during the first few months, but become apparent later.
Apple may recognize the problem as a warranty issue, but if the warranty has expired, you should contact an authorized service center, such as RudService, where they will conduct a free diagnostic and offer a high-quality replacement of the original display.
5. Poor quality of previous repairs
Many users turn to random repair shops, where they install cheap copies instead of original parts. As a result, errors appear on the screen within a few months. spots, lines, or uneven backlighting.
Incorrect installation, poor quality glue or lack of sealing can also lead to this problem.
What types of stains are there on an iPhone display?
To understand how serious the problem is, it is important to differentiate the type of stain:
| Type of stain | Possible cause | Solution |
|---|---|---|
| White (light) | Pressure, backlight, liquid | Replacing the backlight module or the entire display |
| Dark | Damage to the matrix | Only complete display replacement |
| Yellow | Overheating, burning of the adhesive layer | Screen replacement |
| Rainbow | Moisture ingress, delamination | Drying and restoring contacts |
| Blue or purple | OLED color distortion | OLED matrix replacement |
If the stain does not disappear when you reboot or change the image, then the problem is physical and cannot be solved software-wise.
