Number of faults in mobile gadgets is growing in proportion to the emergence of new technologies. Competition is recognized as the culprit of this trouble, because in the race for success you cannot hesitate, otherwise another company will take your place in the sun. As a result, developers do not have time to test devices properly, and imperfect smartphones end up in the hands of consumers.

Problems can vary: from serious ones that impair the performance of the device, to minor ones that spoil the aesthetic component. One of these problems is the yellow spot on the phone screen.

What does the fault look like?

More than half are not insured against this problem modern smartphones. Most often it is mentioned by users of devices from famous brands: Apple, HTC, Samsung (less often than others). But when used for a period of two years or more, such a defect can appear in any brand of device.

A yellow spot on the phone screen can be anywhere, so it is recommended to carefully inspect the gadget when purchasing. It is worth remembering that most often this malfunction visible on a white background, for example, if it is open search results. The intensity of the defect varies: sometimes it looks like a slight darkening on the display, closer to a brownish tint, but there are also very bright spots, as if oil or glue had been spilled under the glass.

Why is this happening?

If a yellow spot appears on your phone screen, there are several reasons:

falling of the device from a great height;
a strong blow to the case from the side or directly to the display;
long exposure to direct sunlight;
liquid ingress;
strong heating from external source(stove, fire, battery, etc.);
the same as in the previous paragraph, but due to the fault of a faulty battery or processor.

All these factors can cause the transistors of some pixels to fail. Because of this, the latter stop working correctly, producing various effects: from colored or duller areas to a “gasoline” rainbow on the display.

There is no need to despair; at this stage, this can still be corrected.

How to remove a yellow spot from your phone screen?

Attention! The methods described below are not suitable if the gadget malfunction was caused by mechanical damage. In this case, only a complete replacement of the display will help. It is produced both independently and in any service center, so there is no need to worry too much about this.

So what to do in other situations? Unfortunately, there are not many options.

Smartphone overheating

If the defect is caused by high temperatures, you should try to cool the device. To do this, you will need to turn off the device, put it in a sealed bag and... place it in the refrigerator. No, this is not a joke on inexperienced gadget owners! This method really helps, but there is one caveat: the temperature in the chamber must be no lower than +8 degrees Celsius.

You need to keep your smartphone cool for just 10 minutes. It is then removed and left to “warm” at room temperature. The next time you turn it on, the yellow spot on the phone screen should disappear.

However, from the secondary appearance of the defect this method doesn't save.

Spontaneous discovery

If the gadget has not been exposed to high temperatures, you can try another method. This will require special program(like ScreenFix Deluxe only for smartphones), which triggers a high-speed change of pixel colors in the desired area. Sometimes this helps remove the yellow spot on the phone screen, but not in case of a factory fault with the display.

Then all that remains is to contact warranty service or service center.
