Modern owners of technology, in particular smartphones, very often have a problem in the form of white or yellow spots protruding onto the display of the gadget. This problem is especially acute among people who own inexpensive phones. Statistics show that such marks on a smartphone screen can appear as early as six months after purchasing the smartphone. Most people are interested in the question: how to remove a yellow spot from the display of your favorite mobile phone? In order to eliminate this problem, it is necessary to determine the cause of its occurrence. Let's do this together.
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.
Cleaning touch screens
To maintain the presentation of your gadget, you need to clean the touch screen correctly and in a timely manner; here are some tips on how to care for your touch screen:
- The screen should only be wiped with microfiber; it will gently remove stains and dust.
- Before cleaning, read the operating instructions for the device. It will indicate how and with what to remove dirt from the screen.
- The phone should be turned off while cleaning the display.
- Purchase special products (polishes or wipes for touchscreens).
- If the cleaner is liquid, apply it first to the cloth and only then to the screen.
Careful use and proper cleaning of the screen will help maintain the presentation of your device, and you now know how to prevent yellowing and white spots from appearing on the display.
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).
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 to remove the yellow spot on your smartphone display
Try to fix the problem yourself. Often, yellow spots on the phone screen appear as technical glue, which is used to attach internal elements. You can get rid of the stain by cooling the area where it appeared. This can be done this way: wrap the smartphone with any fabric to prevent the case from getting wet. And apply a piece of ice to the spot for a few minutes.
If the reason is software, you will be able to solve this problem by resetting the settings to factory settings. A description of this process can be found on the website of the manufacturer of your device. If you have Honor, read this manual.
Screen smudge removal software
In order to remove white and yellow spots on the phone screen, users install a special application - Dead pixel detect fix. This program can be downloaded from the market absolutely free.
Often, with the help of such an application, the phone is checked immediately upon purchase for the presence of suspicious spots on the display. And if a speck appears while using the gadget, then just install the application, launch it and select the “Fix” setting. Then put the phone on charge and wait for the morning. As a rule, all screen defects disappear in the morning.
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:
Is there a way to remove the yellow spot yourself?
It depends on the stain.
It’s just that sometimes users confuse a dead pixel with a stain (a dead pixel is shown in the photo below, spots are shown in the examples above).
If we are talking specifically about a dead pixel, then in some cases it is possible to fix the problem. On how to do this, see this note: https://ocomp.info/monitor-bityie-pikseli.html
Dead pixel found
If we are talking specifically about a stain (especially one that appeared in case of overheating or flooding), then in 99.99% of cases it can only be removed by replacing the screen. No amount of software or rebooting and resetting the device will help.
Moreover, replacing the screen is not the easiest action, and if you have never “done” this, then it is better to immediately send the device for service. However, it is worth saying that some old devices are quite easy to disassemble and repair (it’s unlikely that you have one like this now.).
As for the cost of such repairs: in most cases, replacing a display costs 2-3 times less than buying a new device. What, as they say, is better is up to you to decide.
Additions on the topic are welcome.
With the advent of touch screen devices, they have become more convenient in terms of viewing the displayed information. But due to the fact that the display area has increased significantly, malfunctions associated with it began to appear more often. In this article, you will learn what to do if a yellow spot suddenly appears on the screen of your mobile phone.
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:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
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.
Who will use
So, blue color is perfect for a young man or girl who constantly uses a smartphone. It distorts the texture on the back cover best, which makes it seem even brighter.
"Midnight Black" is suitable for business people. It will be able to emphasize their strict image and become one of the must-have accessories for a business suit. In addition, the P20 Lite in black is not as susceptible to scuffs as the other two bright colors, which allows you to use the device frequently without losing its attractive appearance.
Pink is a great choice for a girl with a bright look. This is truly a unique color that emphasizes a person’s individuality. In addition, according to the stereotype that girls are neater than guys, the P20 Lite in pink is simply created for the female gender. After all, you need to use it with trepidation.
Subtleties of operation
Straight to the point:
- The black body is a real fingerprint collector. All traces of your hands will remain on it, rest assured. However, scratches and abrasions are not so visible on it - it does not shimmer much in the sun, due to the fact that it is not bright. This is where the effect comes from.
- Blue is a true classic of Huawei and Honor. Practical for everyday use, as there are almost no fingerprints left on it. On the other hand, any imperfection of the case (scratches, abrasions) is immediately visible.
- Pink is an incredibly beautiful and at the same time easily soiled smartphone. Everything is visible on it: scratches and fingerprints (although the “fingers” are not as visible as on black). The result is the P20 Lite, which is incredibly beautiful and stylish, but requires the utmost care.
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.
How to choose P20 Lite color
When choosing the color of a flagship gadget from Huawei, pay attention to the following factors:
- Will the smartphone be carried with/without a case?
- Who will use the device?
- Are you careful when using fragile gadgets?
We will analyze each of the presented points in more detail.
Case: is it worth it?
A question to think about carefully:
- Firstly, you are buying a smartphone that is a unique design solution. Are you sure you want to carry it in a case?
- Secondly, if you use your smartphone without protection. How careful are you to avoid scratching the back panel of your P20 Lite?
In general, using the case in combination with the P20 Lite is a controversial issue. However, it has its uses.
So, the case can be used in everyday life - work, study. But if you need to show off your smartphone to someone, you can easily take it off. This way, you can show off your smartphone's attractiveness at the time you need it and also maintain its attractiveness.
The above strategy works best for devices in pink and blue. Scratches are best visible on them, and from any angle. A black device can be used carefully - it is more easily soiled, but damage and abrasions are less noticeable.
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.
Note! Employees of the store where the Xiaomi 5 Plus phone was purchased do not have the right to refuse repairs under warranty. This can only be done at a Xiaomi service center. Sales consultants are not vested with such powers.
Is it possible to return the phone under warranty if there is a similar problem?
In general, if you didn’t drop the phone, didn’t fill it with water (etc.), generally handled it with care and the warranty period has not passed (usually 1-2 years), then you can return the phone.
Important: if you think that an authorized service will not notice that you have dropped your phone, you are deeply mistaken. Fur. damage is clearly visible through cracks, scratches, splinters, etc. (The phone is flooded with liquid - it’s even better visible
