Users often encounter an unpleasant problem - a yellow spot on the smartphone screen that appears from nowhere. It does not interfere with the operation of the device, but it is very annoying and spoils the appearance of the gadget. Therefore, the question reasonably arises of what to do in such a situation. Is it possible to remove the stain and return the screen to its previous condition? Let's look into this issue together.
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.
What is the danger of a yellow spot on the phone screen?
In principle, if the display has turned yellow, then you can continue to use it. But the stain will not disappear, and over time it may increase in size.
If a stripe appears on one edge of the display, this indicates damage to the matrix cable. This happens when moisture gets inside (the contacts oxidize, the signal is not disrupted). As a rule, after this the entire display module must be replaced.
And if the phone screen has turned yellow due to moisture (the defect is more pronounced on the sides of the screen), then you cannot do without completely disassembling the gadget. The presence of moisture inside will cause the contacts on the CPU or memory chips to oxidize, causing the device to simply fail.
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.
Is this a warranty case?
As we have already written, the reasons for the appearance of a defect are different. If the stain is the result of overheating or mechanical pressure, then there is no question of any warranty repair or replacement. Unless you bought special insurance that entitles you to free service for some time.
Sometimes it really is a factory defect. But most often, manufacturers of such devices do not have a developed network of official or authorized service centers: these are the most ordinary “basement Chinese”, contacting them with a guarantee makes no sense.
In rare cases, when yellowness appears as a manufacturing defect in models from a famous manufacturer, you have a chance of getting a warranty replacement. But there is little chance of this. Therefore, most likely, you will have to change the matrix on a general basis.
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.
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.
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.
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
