A dot on an iPhone screen is a dead pixel. White and black dots appear different reasons: mechanical impact on the screen due to impact or fall, factory defect, moisture ingress. It will be difficult to remove the dot, but some methods can still help.

Screen check

To make sure that the specks on the screen are dead pixels, use free app Dead Spotter. It contains multi-colored screensavers that change by tapping the screen. To detect a broken pixel on the display, you need to fill the screen with one color. Dead Spotter allows you to put white, black, red, green and blue splash screens.

On a white background, black dots are visible, on black - white, on red - green, on green - red. If you buy a smartphone from your hands, ask the seller to install the application and check if any spots appear on the screen during operation.

Dead pixels can also appear on new devices that have just been bought in stores. Apple's policy in such cases is aimed at meeting the user's requirements: if there is at least one dot on the smartphone screen, you can contact the store or service center and be sure that the device will be replaced.

There may be more stains on Apple laptops. If the screen size is larger than 22 inches, a maximum of 16 dots is allowed. For more information, you can contact technical support, since the allowed number may vary depending on the size of the display.

Dead pixel treatment

The dot on the screen of your iPhone can have a different nature of occurrence, on which it depends whether you can get rid of the spot:

• A dead pixel never lights up. This is a black burnt point, which cannot be restored. It remains only to accept and not look at this part of the display.
• A stuck pixel displays two or one of the three colors. The dot appears black on green, red, and blue backgrounds. Such a defect can be eliminated by software and mechanical methods.

To increase efficiency, it is necessary to use both a software and a mechanical method. This will not harm the phone in any way, and there will be more chances for the restoration of the pixel. If he's not completely dead yet, of course.

Program method

You can revive a stuck pixel using a special stimulating window in which multi-colored dots flicker. You don't have to download anything, there is a ready-made tool on the jscreenfix.com website.

1. Run on iPhone Safari browser, go to jscreenfix.com.
2. Scroll down the screen and click "Launch JScreenFix".

A page will open with a window with blinking dots. Set it to close the problem area on the display. Wait at least 10 minutes (the longer, the better the chances of recovery). After treatment, you need to make sure that the pixel is awake. To do this, run the test again in the Dead Spotter app. If the dot remains, try to make a few more visits, increasing the duration of the blinking window on the problematic area of ​​the screen.

Mechanical impact

Together with the software method, use the method of mechanical impact on the damaged pixel.

1. Remove the protective glass, if installed, clean the display from dust.
2. Turn off the screen (you can not turn off the phone, but just put it on the lock).
3. Use a lint-free cloth to avoid scratching the display. You can use monitor wipes. Gently knead the area with the damaged pixel for 10 minutes.

The main thing when massaging the screen is not to overdo it with pressing force and not damage neighboring pixels. If the problem still persists with the screen off, unlock your phone and repeat the procedure.

Heating or cooling

Users on the forums report that cooling or, conversely, heating the screen helped them. For cooling, the smartphone is sent briefly to the freezer. If you leave the phone there for a long time, it will be covered with frost, and when it melts, moisture will get into the case. For some users, after cooling, the spots disappeared, for others they became even larger, so it’s better not to risk it again.

With heating, too, everything is not so simple, but you can try:

1. Heat water to boiling point.
2. Soak a lint-free cloth in boiling water and place it in a plastic bag.
3. Using this heating pad, knead the problem area for 5 minutes in a circular motion.

Remember that you perform all actions at your own peril and risk. If the point is small and not conspicuous, it is better to ignore its existence, otherwise you can make things worse.
