HOW TO REMOVE A STAIN ON YOUR PHONE SCREEN. A black spot appeared on the screen.

Imagine the situation: you recently purchased a brand new iPhone and after several days of standard use, unpleasant yellow spots and stains suddenly appeared on its screen, especially noticeable on a white or light gray background.

At the same time, no “traumatic” or curious situations happened with the device, that is, there were no reasons for disruptions in the operation of the display.

Then why do yellow spots appear and how to fix it?

Why do yellow spots appear on the iPhone screen?

It is quite difficult to establish the exact cause of the described problem, but most often the adhesive used in assembling the module is to blame for the appearance of spots on the display. Although the company itself has not commented on user complaints, a number of experiments have shown that yellowish stains appear on the surface of the screen if the reagent used to glue the glass did not have time to completely dry and evaporate before the gadget was released for sale. In this case, all such manifestations should disappear after a few days if the device is placed in a warm and dry place. Also, the problem can resolve itself within several days of active use of the device.

Alas, the long drying period is not the only drawback of the fastening substance torn out by the Americans. For example, spots on the display may appear as a result of exposing the device to extremely high or low temperatures. That is, the screen can be damaged if you drop your iPhone in a snowdrift for several hours or forget it under the sun during the most active period of the day. The glue may also turn yellow due to a sudden change in the temperature of the external space. in case of yellow spots, lasts only 2 hours.

In addition to the problems described, the answer to the question “Why do yellow spots appear on the iPhone screen?” The most common occurrence of moisture getting inside the case may be. If water seeps under the display glass, it can disrupt the color matrix, causing it to stop displaying certain colors normally. Wetness also results in permanent multi-colored (including yellow) spots and stripes on the display.

In addition to the factors described, smartphone software affects the disruption of normal image transmission. For example, some “non-native” programs or applications for the camera can lead to the appearance of spots on the display, but most often such spots are non-static, that is, each time they have a different shape and appear in different places. Of course, mechanical impacts on the screen area can also damage the internal color display systems, which can lead to various spots, stripes and dots throughout the display.

Typically, the iPhone works without failures or problems for many years, but sometimes multi-colored spots (yellow, blue, white or black) may appear on its screen. If the phone is under warranty, then the first thing you should do is take advantage of it, as there is a possibility that it is a manufacturing defect. But if you are to blame for the occurrence of such malfunctions, then you should contact a service center.

Causes of spots

The appearance of spots on the Apple display can be caused by the following reasons:

• software glitches;
• overheat;
• moisture ingress;
• mechanical damage.

Software failures usually lead to light spots, which can be cured by changing the firmware. This operation is quite accessible to the average user, but it is worth remembering that any interruption of the firmware process (for example, due to a power failure) will simply disable the device. Therefore, everything must be done using an uninterruptible power supply. And even better - in a service center, where its employees will be responsible for such failures.

Overheating can lead to changes in the properties of the adhesive that joins the layers of the display module. And if a yellow spot appears on the display, then most likely this is our case. This is usually a consequence of a manufacturing defect and will therefore require replacement of the temperature sensor. The display will also have to be replaced, since its restoration is extremely rare.

Liquid getting inside the iPhone leads to oxidation of the screen cable contacts. The consequences of this appear after some time and can be very diverse - from stains to complete inoperability.

And the most unpleasant thing is mechanical damage when the phone falls. Firstly, this is definitely not a warranty case. Secondly, as a result of the impact, microcracks can form, due to which the crystals are destroyed. The result is dark spots and the need to replace the screen.

A dot on an iPhone screen is a dead pixel. White and black dots appear for various reasons: mechanical impact on the screen due to an impact or fall, manufacturing defects, moisture. Removing the point will be difficult, but some methods can still help.

Checking the screen

To make sure that spots on your screen are dead pixels, use the free Dead Spotter app. It contains multi-colored screensavers that change by tapping on the screen. To detect a dead pixel on the display, you need to fill the screen with one color. Dead Spotter allows you to set white, black, red, green and blue screensavers.

Black dots are visible on a white background, white dots on a black background, green dots on a red background, and red dots on a green background. If you buy a smartphone secondhand, ask the seller to install the application and check if spots have appeared on the screen during use.

Dead pixels can also appear on new devices just purchased in stores. Apple's policy in such cases is aimed at satisfying the user's requirements: if there is at least one dot on the smartphone screen, you can contact a store or service center and be sure that the device will be replaced.

Apple laptops may have more stains. If the screen size is greater than 22 inches, a maximum of 16 dots is allowed. To clarify the information, you can contact technical support, as the allowed quantity may vary depending on the size of the display.

Dead pixel treatment

A dot on the screen of your iPhone can have a different nature of occurrence, which determines whether you can get rid of the stain:

• A dead pixel never lights up. This is a black burnt point that cannot be restored. All that remains is to accept it and not look at this part of the display.
• A stuck pixel displays two or one of three colors. The dot appears black against a green, red, and blue background. Such a defect can be eliminated using software and mechanical methods.

To increase efficiency, it is necessary to use both software and mechanical methods. This will not harm the phone in any way, and there will be a greater chance of pixel recovery. Unless he's completely dead yet, of course.

Software method

You can revive a stuck pixel using a special stimulating window in which multi-colored dots flash. You don’t have to download anything; the ready-made tool is available on jscreenfix.com.

1. Launch the Safari browser on your iPhone and go to jscreenfix.com.
2. Scroll down the screen and click "Launch JScreenFix".

A page will open with a window with blinking dots. Adjust it to cover the problem area on the display. Wait at least 10 minutes (the longer, the higher the chances of recovery). After treatment, you need to make sure that the pixel wakes up. To do this, run the test again in the Dead Spotter app. If the dot remains, try making a few more passes, increasing the duration of the flashing window on the problem area of ​​the screen.

Mechanical impact

Together with the software method, use the method of mechanical impact on the damaged pixel.

1. Remove the protective glass, if installed, and clean the display from dust.
2. Turn off the screen (you don’t have to turn off the phone, just lock it).
3. Use a lint-free cloth to avoid scratching your display. You can use wipes to care for your monitor. Knead the area with the damaged pixel using light movements for 10 minutes.

The main thing when massaging the screen is not to overdo it with pressing force and not to damage neighboring pixels. If the problem cannot be resolved with the screen turned off, unlock the phone and repeat the procedure.

Heating or cooling

Users on forums report that cooling or, conversely, heating the screen helped them. To cool, the smartphone goes into the freezer for a short time. If you leave the phone there for a long time, it will become covered with frost, and when it melts, moisture will enter the case. For some users, the spots disappeared after cooling, for others they became even larger, so it’s better not to take any risks.

With heating, not everything is so simple either, but you can try:

1. Heat the water to boiling point.
2. Soak a lint-free cloth in boiling water and place it in a plastic bag.
3. Using this heating pad, knead the problem area for 5 minutes in a circular motion.

Remember that you perform all actions at your own peril and risk. If the point is small and not noticeable, it is better to ignore its existence, otherwise it can make things worse.
