Small Dot in the Upper Left Corner of Android Phone? – Easy Fix



Every cellphone has a different meaning to the small dot on the screen. The black dot on the left corner of the iPhone next to the battery percentage means that the cell phone is low on charge. Besides the black dot, there are different color dots, and every dot links to some background application running. However, things are different in android mobiles like Samsung.

This article covers everything you need to know about the small dot in the upper left of the Android phone.

Why Does a Small Dot Appear in the Upper Left Corner of My Android Device?

These dots show up when pixels are having some issue, and it might be a green, a red, or a blue dot. You don’t need to worry if you see any of the mentioned color dots because they will vanish after the calibration or by changing the wallpapers.

If you see a white color dot on the left corner of the screen, it might be the stuck pixel, and you can recalibrate it. Also, by changing the wallpapers frequently, the white dot would go away. You only need to worry when you see a black dot as it can be a dead pixel, or you may have damaged your display. Samsung users have faced this issue a lot.

What Is the Black Dot in the Top Left Corner of My Android Phone?

The black dot on the phone screen could result from dead pixels. A pixel is the smallest color unit displayed on any digital device. These pixels are arranged in a grid to create an image. You have to combine lots of pixels to form an image. Most of the black dots are so small that you cannot see them with the naked eye, but you can zoom the image to make the pixels visible. Samsung mobiles are known to have an electronic defect that results in a black or white dot.

The black dot goes out and comes back randomly. Before you consider that you have damaged your screen, it is better to confirm if it’s a dot for any notification. To check that, you need to take the screenshot, and if you see the dot in the screenshot, it isn’t a bad pixel. If it isn’t visible in the screenshot, your mobile phone has a damaged screen.

Can LCD Damage Cause the Black Dot?

The black dot on the Android phone is also called the inkblot. A gradual pressure that leaves the front glass intact while damaging the display underneath can be the reason for the black dot. This inkblot spreads with time, leaving your screen dead and damaging the LCD.

The LCD contains the tubes that contain liquid crystals. If any of the tubes break, it will leak the liquid causing the black dots on the screens.
