Reasons for the appearance of black spots on the screen of a touch phone
Most often, black spots on a smartphone appear unexpectedly. The gadget did not fall anywhere, did not hit, did not come into contact with moisture. But a strange blotch appears on his screen. Or even several small sizes. Moreover, their colors and shades may also vary depending on the occasion. This area may change upon contact with them. Or be unshakable.
The reasons for the appearance of spots on the screen of a mobile phone are different:
Causes: | Peculiarities: |
From blows, falling phone | As a result, defects appear in the screen matrix. Such spots will have a uniform black color when the device is turned off and on. And that will also mean that the pixels of this spot cannot be restored. |
Touchscreen sticking to device display | In devices that have an air space between the touchscreen and the screen. In this case, the spots look almost transparent when the smartphone is turned on. And they are clearly visible when the device is turned off. |

Now let's figure out how to fix all the listed problems on your mobile device.
Actions in case of stains
The only reasonable solution when this malfunction occurs is to use the services of a specialized service center. In most cases, it is not possible to solve such problems on your own due to the fact that you will need to have the appropriate skills and equipment.
To check your phone screen, the best option would be to contact the service center specialists directly, who, using modern technology, will be able to perform a high-quality replacement of the display. At the same time, smartphone owners can be sure that only original spare parts are used.
Where do spots of different colors appear on the phone screen?
After using their phones for a long time, some users notice the appearance of yellow or white spots on the display surface, preventing them from viewing text or images properly. This problem is typical for budget mobile devices, but also occurs on expensive devices. The main cause of the defect is violation of operating conditions. An additional reason may be a manufacturing defect made by the manufacturer.
How to remove dark spots that appear on your smartphone screen
Mobile devices have different organization of touch screens. There are dozens of such schemes. And in some cases, more often in tablets, the screens are built in such a way that there is an air gap between it and the touch field.
When you press the sensor with your finger, the field of the screen surface bends and indicates on the sensor which area is involved. Also, during physical impacts, two contact fields can stick together. And you will see a barely noticeable stain when the device is turned on.
Slightly noticeable stain on the phone screen
In this case, it will not be difficult to get rid of the defect at home. You will need any suction cup.
Suction cup for removing stains on the screen
You can buy it at a children's store. We will use a suction cup to level the surface of the smartphone.
- You need to attach a suction cup to the edge of the spot. If it does not stick well to the screen, moisten the surface of the suction cup;
Attach a suction cup to the edge of the spot
- Using sharp, but not strong movements, pull the suction cup towards you so that the upper part of the screen lags behind the bottom;
- Attach the suction cup to the other edge and do the same;
- Depending on the size of the spot, the suction cup must be attached to different ends of the defect.
The spot on the screen has disappeared
With these steps you will get rid of the flaw in your phone's sensor. The suction cup can completely fix such faults on tablets, mobile phones and touch screen desktops.

↑ How to fix the problem
This most common problem occurs due to damage to the mobile phone screen, so there is no need to waste time looking for a miraculous solution because you won’t be able to find one. What you need to do is buy a new screen of the same model, you can buy a screen cheaper in China, but you will have to be patient, since your screen may be on the way for a month, or even more. Then contact a specialist to remove the damaged screen and install a new one.
Another way to eliminate black marks on the display of a mobile gadget
Very often, spots on a smartphone screen are black and do not change color under any circumstances. They can appear even without damage and without moisture. As a result of the failure of some pixels. Most likely, such a device has been used for a long time. And in these cases it can be difficult, if not impossible, to get rid of them. But it's still worth a try. Black spots may disappear partially or completely with pressure. Try pressing on the formation with your finger. If there is progress for the better, then your case is not hopeless.
Try to get rid of it by pressing on different areas of the stain. You can also try warming it up before applying pressure. In this case, you can use warm air from a hairdryer. Service centers try to remove such stains using a pressure chamber. If you have this device, use it. But before placing the smartphone in the camera, you need to remove the back cover and battery.
Cases of manufacturing defects cannot be excluded. Often black and dark spots appear on the smartphone screen almost immediately after purchase. There is nothing to think about here - you need to return to the store and demand that the device be replaced with another one.
Dark spots on the screen of a new phone
Or demand a refund, depending on the conditions described in the warranty card. Blotches on the screen with a manufacturing defect are usually multi-colored, like gasoline that has fallen into a puddle on the street. This also means the poor quality of the adhesive material that holds the touch panel and display together.
Why yellow spots may appear
Smartphone overheating
This is probably one of the most common causes of stains. By the way, in this case they most often appear on the sides of the screen in the form of small stripes with an orange-yellow tint along the edges (as in the example below in the photo).
I cannot help but note that overheating is an insidious thing and many users do not even notice that during games (and other resource-intensive applications) the temperature inside the smartphone has increased significantly. In this regard, I recommend that you read the article linked below.

Flooding the device with water
This is another extremely popular problem (note: so far 98% of smartphones are not waterproof, and perhaps manufacturers will someday improve this point). Often the phone simply falls into water somewhere in nature, in the bathroom, or gets wet in the rain (many people don’t even attach any importance to this.).
By the way, not only the screen suffers from water, but also the battery, microphone, speakers, and all the microcircuits inside the device. A characteristic feature of yellowness with a “good” flood is the large size of the spot and its weak intensity (as in the example below).
Note: when the device is flooded, white spots also often appear.

Factory defect/battery problem
If you have handled your phone with care and it is not yet a year old, then the appearance of stains can most often indicate a manufacturing defect (this usually happens with the cheapest devices). Pay attention to the phone body and battery (the fact is that sometimes batteries can swell and, because of this, put pressure on the screen, which causes stains to appear). An example in the photo below.
Swelling of the phone (battery)
If the battery is swollen, do not delay replacing it with a new one ( Important! In some cases, such batteries can even ignite!).
Note: on some cheap Chinese devices, spots appear on the screen after 2-4 years of use. Moreover, even if you handled the phone very carefully (the point is the low quality of components, for example, glue.).
Strong pressure on the screen / fall / fur. damage
I don't think there's much to comment on here. In this regard, it can be noted that users most often:
- accidentally sit on the device when it is in the back pocket of their trousers;
- they drop when they pick up the phone with wet (wet) hands;
- They put a lot of pressure on the screen (sometimes when freezing and braking).
Matrix burnout, poor-quality glue between the touchscreen and display
Matrix burnout occurs after long-term use (more than a year) of cheap smartphones with low-quality components. Nothing can be done about this except replacing the display with a new one (what’s interesting: manufacturers of such cheap equipment seem to use a “calculator” to calculate how long their device will last - and just after the warranty period you are faced with a similar problem
