All gadgets with touch screens have one similar problem: spots appear on the smartphone display. The reason is careless handling: touching with fingers or carelessly throwing into pockets, on tables, in bags. So the display needs to be cleaned periodically. When removing stains from your iPhone, you shouldn’t lose sight of a few simple rules.

How to clean an iPhone display

An oleophobic coating of the thinnest structure can protect the screen from grease. However, if handled incorrectly, this coating will deteriorate.

So cleaning should be done with extreme care, using only a microfiber cloth. You can buy it at a computer store, or you can even buy an optics cloth. The following cleaning steps are provided.

  • The device is turned off, all cables are disconnected, the ports are covered with adhesive tape.
  • A microfiber cloth is used - soft, fluffy. Use it to carefully wipe the screen. To avoid damaging the coating, do not press on it.
  • Without touching the joints and ports, wet wipe wipe the device. In this way, stubborn spots, streaks and stains, and sticky marks are removed.
  • After wiping, the iPhone should be wiped dry.

Important! Do not wash the phone, use paper towels or use abrasive materials.

What if the black spots can’t be wiped off?

The liquid used is intended for cleaning the display. You cannot use acids, vinegar, or other household chemicals: they will destroy the oleophobic coating layer.

Spots of special origin

  • The device fell and the matrix cracked. Then black spots appear.
  • Yellow spots occur when the smartphone overheats. Overheating can occur due to the gadget being near heating devices or in the sun.
  • White spots may appear after exposure to moisture or strong pressure as a result of an impact.

Yellowness appears due to damage to the adhesive layer of the display. And the yellowing screen of a new phone is a sign that the glue has not yet dried. After a while, the spot will dry out and most likely disappear.

It is best to immediately visit our service center to have your gadget repaired. It is convenient and relatively inexpensive.

When people buy an iPhone, they begin to think that this phone will be simply flawless and there will be no problems with it. But unfortunately this is not so and one of the iPhone problems — yellow spots on the screen.

I myself have encountered this situation and my friends too, so I have some experience with this issue and I will be happy to share all the information with you.

Why do yellow spots appear on iPhone?

So, first I’ll tell you about my case. It was an iPhone 4S and it served me for 4 long years. In principle, he is still in good condition and serves as my second phone.

Somewhere after the third year of use, a yellow spot appeared on the left side of the screen. It was not too big and is best seen against a white background.

Out of curiosity, I once went to the service center, to which, without an answer about the reason, they simply told me that I needed to change the screen. Not knowing the reason for the appearance, I simply continued to use my smartphone.

A little later I turned to a friend who started studying iPhone repair and then a version appeared that it was due to moisture and it was simply impossible to remove it.

This whole story ended with the fact that I dropped my gadget and the screen did not break, but stopped showing the image. And then we had to change the display.

After reading on the forums, the most popular versions are:

  • not dried glue;
  • moisture;
  • pressure on the screen;
  • high and low temperatures.

What the actual reason is is generally impossible to find. Therefore, I’ll simply tell you what to do in such situations and how to live with it further.

What to do if yellow streaks or spots appear on your iPhone?

When this yellow spot appeared on my iPhone, I was really upset. After all, the phone served for a long time without any incidents and this made me incredibly happy.


But as you can see, nothing is perfect. And from my life experience, you only have three options if you discover this miracle:

  1. go to the service center and change the screen;
  2. if it’s under warranty, then we go to the store and demand to exchange it for a new one;
  3. We just walk around with the stain and try to get used to it.

At one time, I chose the third point, because the stain is quite small and does not particularly interfere with the work. Replacing the original display with something incomprehensible is also not a good option.

But as I wrote above, by coincidence, I changed the display. I was lucky that they just found the original donor for this case.

conclusions

Typically, this problem has been the most common since iPhone 4. This does not seem to be the case with modern ones, but yellow spots are quite an insidious thing.

I would like to wish you that on your iPhone more no such spots appeared. After all, sometimes the cost of a screen simply goes through the roof and not everyone wants to spend extra money.

Sometimes you may get unlucky and after a couple of months or more, ("dead") dead pixels may appear on your display.

An excursion into history. What is a dead pixel?

The image on a monitor with a liquid crystal display, as with a cathode ray tube, consists of dots, locally called pixels. They are the ones that form the various pictures that we see through changing colors. The pixel also has its own permanent hierarchy - three subpixels, black, red and green. The final color is achieved by changing the position of individual subpixels and pointing towards it light beam different power. IN modern monitors, using the so-called active matrix, each pixel is controlled by its own thin film transistor (TFT, Thin Film Transistor), the failure of which forms on the screen black inactive point - dead pixel . It does not change its color when the image changes precisely because of a technical malfunction of the control transistor. Such dead pixels can only be restored by replacing the corresponding transistor, which can only be done in special laboratory conditions, which is clearly not available to ordinary users.

If you are so “lucky” and you have just such a black dot on the display of an iPhone, touchscreen or even a monitor, then good luck... But if you have a dead pixel glowing, let’s say brightly green, as was the case in my case with the iPhone 3GS, then you can “revive” it!

Stuck dead pixels

There is another type of dead pixels - stuck . A sign of their appearance will be a light dot on dark background. This happens when an individual subpixel gets stuck in one position. Respectively it does not respond to changes in the image on the display, but lights up in a certain way light color . Such defects, unlike blackheads, can be restored at home through some software and physical manipulations.

Unfortunately, I didn’t take a photo of this pixel when it wasn’t working, but there are many “lucky” people on the Internet with similar symptoms.


Treating a dead (stuck) pixel

The essence of the method is simple, suitable for both iPhone display and LCD monitor. For monitor owners, go to the website http://www.jscreenfix.com and click on Launch the JScreenFix. A window appears with small colored dots that quickly change color.

The trick to this method is that it performs high-speed color changes on individual pixels, allowing you to programmatically realign a stuck pixel.
