The iPhone is known for its sleek design and impressive display. However, like any electronic device, it’s not immune to issues, including dead pixels on the screen. Dead pixels are those tiny, unresponsive spots on your iPhone’s display that can be annoying.
This article discusses the difference between stuck and dead pixels, the common causes of the dead pixels and how to deal with them.
Difference between stuck and dead pixel
Fixing a faulty pixel is important, but it’s just as crucial to identify whether it is a stuck or dead pixel. A pixel is when a small part of the screen gets stuck and shows a solid green, blue, or red colour, as dictated by its sub-pixel.
On the other hand, a dead pixel remains completely unresponsive. When you activate your screen, it won’t light up and will appear as a dark spot, only noticeable when compared to colourful or bright white backgrounds. Stuck pixels are relatively simple to resolve, but dead pixels may never work again.

How to detect a faulty pixel?
The simplest way to spot these unresponsive pixels is by using various coloured backgrounds on your phone. Here’s how you can do it:
- Start by cleaning your iPhone’s screen to remove any dirt or debris. A lint-free cloth works well to ensure a clear view.
- Visit the App Store and download the Display Test Pattern app for iOS.
- Launch the app and select the Colour fill option to test your phone’s screen.
- If you observe any dots or patches that appear different from the background colour of your phone, this may indicate the presence of dead pixels. If the issue persists when displaying a white background, you’ll likely see a black dot, signifying a dead pixel.
- If you notice this unresponsive pixel in various colours, it’s probably a stuck pixel, which can often be fixed.
Common causes of dead pixels
Here are a few common reasons that might cause the dead pixels on your iPhone:
- Manufacturing defects: Dead pixels can be a result of manufacturing defects. During the assembly of the iPhone’s display, individual pixels may become faulty, leading to dead pixels. These defects are relatively rare, thanks to rigorous quality control measures, but they can still occur.
- Physical damage: Accidents happen, and sometimes, physical damage can lead to dead pixels. If your iPhone gets dropped, exposed to excessive pressure, or experiences any form of physical trauma, it can damage the pixels on the screen, causing them to become unresponsive.
- Software glitches: Sometimes, dead pixels are not a hardware issue but a software glitch. Software-related problems can cause pixels to stop responding correctly. In such cases, a simple reboot or software update may resolve the issue.
- Ageing and wear and tear: As your iPhone ages, its display can experience wear and tear. Over time, the pixels may degrade or become less responsive. This natural deterioration is unavoidable, but it’s a slow process and typically happens after years of use.
How to deal with the stuck and dead pixel?
Dealing with stuck pixels and dead pixels on your iPhone or iPad can be frustrating, but there are a few methods to try:
How to fix stuck pixels on iPhone?
Stuck pixels are usually easier to address, and you can attempt to revive them using third-party software or go to your local Apple repair store (or an authorised one) and ask for support.
If you’re using a third-party app, launch the app and follow the steps below.
- Position the pixel fixer frame over the problematic pixel on your device’s screen and let it run for about 10 minutes.
- Afterwards, remove the pixel fixer frame and check if the stuck pixel has been resolved. It may take a few attempts to succeed, so don’t give up if it doesn’t work immediately.
If the issue persists despite repeated attempts, it might be a hardware problem, and you should seek professional help from the Apple Store.
How to fix dead pixels in iPhone?
Dead pixels are trickier to fix since they often involve hardware issues. If third-party software doesn’t help, you can try the following methods:
Fix the pixel using pressure
It does not always work as it is really hard to fix the dead pixels, but you can try to revive the dead pixel by using some pressure on the dead pixel; here is how to do it:
- Wrap a soft, lint-free cloth around the eraser end of a pencil or your finger.
- Apply gentle pressure to the screen in the area with dead pixels.
- Tap the screen lightly to dislodge any impurities without applying excessive force.
Fix the pixel using heat
Another fix that can revive the dead pixel is heat; here is what you can do:
- Warm some water, but don’t let it boil.
- Pour the warm water onto a lint-free cloth.
- Using gloves, place the cloth in a sealed plastic bag, like a sandwich bag.
- Gently massage your iPhone’s screen in circular motions, paying attention to the area with dead pixels.
Warranty coverage
If your iPhone is relatively new and still under warranty, and you discover dead pixels, you should contact Apple. They may offer a replacement or repair under warranty, especially if it’s a manufacturing defect.
