What to do if a yellow spot appears on your phone screen?

Why does this defect appear?

Let’s make a reservation right away: a spot on the Xiaomi Redmi Note screen can be not only yellow, but also white. In rare cases, when the matrix is ​​damaged, there are others - red, blue, orange. This spot appears for a number of reasons:

1. Overheating of the screen – avid fans of mobile games use their phone more intensively. Some people are so addicted to entertainment apps that they launch them while their phone is charging.
2. Matrix burnout – budget models of Xiaomi smartphones are susceptible to this disease. The manufacturer is forced to save money by installing low-quality displays in devices. As a result, the price of a new phone is low, as is the lifespan of the screen.
3. Moisture penetration - if liquid flows under the display, a white spot with torn edges will form on it. The manufacturer does not recommend using the smartphone in the bathroom, swimming pool or other body of water.
4. Using glue - in some models it is used to attach the touchscreen display. Over time, it turns yellow, and a hated stain appears on the screen.
5. Screen transformation - intense pressure, impacts or friction can cause a yellow spot to appear. Some users note that the defect occurred due to carrying a smartphone in a narrow trouser pocket.
6. Mechanical damage - a strong blow to the display area leads to stains. This type of breakdown is especially common in families with small children. To protect your device, use covers and additional glass, plastic films.
7. Manufacturing defect – 3-5% of potential buyers may become the owner of a defective device. The manufacturer is trying its best to reduce this percentage to a minimum. However, as long as smartphones are assembled under the supervision of people, it will not be possible to avoid the human factor.

You shouldn’t think that the yellow spot on the screen is a problem exclusively with Xiaomi phones. The defect may appear on devices from more famous manufacturers, such as Apple, Samsung, Meizu, Huawei.

What does a yellow spot on a smartphone display indicate?

Yellowness appears on displays with an IPS matrix. Owners of AMOLED screens cannot avoid the defect either, but it looks different: like dots of a certain color - broken (defective) pixels. Spots on AMOLED are formed when the display is mechanically damaged, for example, by indentation.

Most often, owners of cheap smartphones complain about the problem. And it’s not surprising, because when assembling them, they use low-quality touch films and distribute the heat incorrectly.

Which reason is most common?

According to reviews from owners of Xiaomi Mi4 smartphones, one of the most common defects is:

• Large yellow spot in the middle of the display.
• A few white ones around the edges.

This indicates overheating of the matrix inside the phone. Moreover, it is not necessary to constantly use a smartphone or play mobile games.

The matrix may heat up due to the use of non-original chargers.

The manufacturer warns in advance about possible defects, but for many, the desire to save comes first. Overheating of the matrix can also cause improper operating conditions. For example, when leaving a smartphone on a windowsill or car dashboard in hot weather.

The second most common reason is manufacturing defects. Smartphones are included in the list of technically sophisticated devices, just like personal computers.

The spare parts inside them are packed closely due to the small size of the device. If the assembly is poor, the battery may put pressure on the display. Therefore, if you notice swelling first, do not delay and urgently replace the battery.

The main reasons for the appearance of yellow spots on the phone screen

The touch screen of a smartphone can take on different colors when malfunctioning: blue, black, grey, white and even the color of the rainbow. But it turns yellow in a situation where the matrix has been exposed to moisture penetration. Phone touchscreens are made up of several layers: thin plastic, pixels shaped like small light bulbs, and a device called an inverter.

Their composition may vary, since there are many types of touch screens. When water gets near LEDs or light bulbs, they can stick together. In this "watery" area, the light will not diffuse correctly. And a white spot, close to yellow, will appear.

If the stain appears some time after purchase, then such a defect can be attributed to a manufacturing defect. Most likely, several mistakes were made during its assembly. Some screen assembly mounting screws may be longer than required. This may cause some internal parts to prop up the screen area. And with certain actions, the stain could appear only after some time. For example, because you used your phone while it was in your back pocket.

If there are manufacturing defects or technical reasons for the appearance of colored spots on the smartphone screen, they will not move.

No matter how you change the orientation of the body. Try to move the stain in every possible way to make sure of this.

Is it possible to remove stains from the screen yourself?

Let’s answer right away – it is impossible to remove the yellow spot on the Xiaomi Mi5 screen using third-party software. Only a complete replacement of the display can help. There is no other way to eliminate defects caused by overheating of the matrix.

Some smartphone app developers claim that their software can help solve the problem. One of these is Dead Pixel Detect Fix.

You can easily download it from the Play Market store. But if you read reviews from other users, your enthusiasm will quickly subside. Some compare this application to homeopathy.

The stain may disappear for a while, but will inevitably appear again.

Apps like Dead Pixel Detect Fix can help test your display. It will launch different colors. Thanks to this, you can see the presence of dead pixels and other factory faults.

In addition, if you google what to do with the stain that appears on the screen, you will be given extremely extravagant advice. For example:

• Place the phone in the freezer.
• Rub the stain with gasoline or acetone.
• Replace the battery.
• Change the firmware version.
• Reset completely settings.

Remember, the problem is solely a faulty display. Only noticing the part can eliminate it. Using one of the above tips, you can completely “kill” your Xiaomi Redmi Pro.

I would like to dwell on the first method in more detail. When you place the smartphone in the freezer for 10-15 minutes, the stains on the display really disappear.

The temperature in the refrigerator should be no more than +8°C. However, such fluctuations harm the device’s battery. During further use, it may hold a charge worse or swell.

Device screen diagnostics

In addition to the reasons already listed, there are also others, including software reasons. Applications from the Play Market will help you accurately determine the cause of the breakdown. Most smartphones are already equipped with similar utilities that can test the screen. All these tools are aimed at determining whether there are dead (non-working) pixels on the screen of your mobile device. Accordingly, if they are, then the entire touch screen needs to be replaced. Or their repair.

The built-in utility is called from the Recovery menu screen. Or from the engineering menu. Almost all Samsung and Lenovo have similar tools. You can read more about them in the device manual.

And we will look at a more universal way to identify and eliminate dead pixels using mobile applications:

Try downloading and installing the program from the Screen Test link.

It is a simple and free tool that displays several graphics modes so that we can notice defects on the screen. If any exist.

To switch modes, touch the screen. The application can also be used on tablets. Use healing utilities that can eliminate dead pixels in some cases. Try installing and running the “Dead Pixels and Phantoms Treatment” utility. The program checks and immediately eliminates pixels or matrix points that display colors incorrectly. The application can help you understand what to do if a yellow spot suddenly appears on your phone screen.

A small yellow spot appeared in the corner of the screen on my smartphone. God bless him, but it is increasing little by little and is already starting to irritate. Tell me, is there a way to remove it, and in general, why did it appear?

This problem is not uncommon (and what’s interesting is that in some cases, in addition to yellow spots, white spots may appear; other colors are rare).

It is hardly possible to single out one specific reason for their appearance without knowing what kind of device it was and how it was operated. Below I will summarize and present the most common of them (and also whether something can be done about them).

Will a smartphone with a stain be accepted under warranty?

It is impossible to answer this question unequivocally. If you used the device extremely carefully, that is, did not throw it, operated it according to the instructions, feel free to go to the point of sale or to the official Xiaomi service center. The main thing is that the warranty card does not expire. It is 1 year from the date of purchase.

Experts advise immediately contacting a repair center, bypassing the point of sale.

Some unscrupulous or unknowing sellers will claim that the stain has nothing to do with the warranty. You can find the addresses of authorized smartphone repair points in the coupon or on the official Xiaomi website.

If the stain appears due to mechanical damage, the display cannot be repaired under warranty. Specialists, of course, will take the device for diagnostics. But after the device is opened and chips and cracks are visible, the smartphone will be returned to you.

Overheating of the mobile phone case

Yellow spots appear most often due to prolonged and intense use of a mobile device. Regardless of the model and brand, the main enemy of phones is heat. Manufacturers are trying to make them more powerful with each new version of the line. But there is no cooling system as such. Since the compactness of the case is also an important parameter for the user. If you have often noticed how, after several hours of playing or working, your smartphone began to get very hot, then streaks on the screen appeared for this reason.

The elements that make up the sensor of your mobile device simply burn out due to high temperature. As a result, yellow-white spots of different sizes and shades appear. If a yellowish spot appears on your phone screen due to high temperature, then you most likely cannot do without replacing the display module.

But you should not immediately contact technical service. Since they can fix us a practically working smartphone. But you still have to pay.

What to do if the breakdown occurred due to the fault of the owner

If you are denied free repairs, you will have to repair the phone at your own expense. You can contact any Xiaomi smartphone repair shop. The cost of replacing a display module varies from 700 to 1,500 rubles.

Those who know how to hold tools in their hands can try changing the screen themselves. The new module can be ordered on Aliexpress. Replacing the display on new Xiaomi models is a very painstaking process. You need to attach it with a lot of glue.

If you are not confident in your abilities, it is better to contact a service center. Otherwise, you risk spending much more money on correcting your mistakes.

You can see clearly all the ways to remove stains on the screen of Chinese smartphones from the video review at the link:

As you can see, you are not the only one who has encountered the problem of yellow spots appearing on the screen of your Xiaomi smartphone. This defect can be eliminated under warranty if no traces of mechanical damage are found on the phone. Otherwise, you will have to replace the display at your own expense. Don't delay fixing the problem to avoid additional costly problems.

Local overheating

This phenomenon is typical for devices where the manufacturer did not take care of proper heat dissipation. In the place where the device overheats, the films are deformed. This is also due to the fact that the film is constantly exposed to high temperatures. After the smartphone cools down, the film does not return to its original shape. Moreover, in the place where overheating occurred, the display will need to be replaced.

In most cases, the place where stains occur is at the ends of the display. They are characterized by a yellow tint, which becomes lighter closer to the edges. Overheating spots do not change their shape and after a certain period of time they may appear even larger.
