Fifty-fifty among two identical phones, you tin accept black spots that look the same simply are caused by completely different issues.

We’ll go over the most common causes of the blackness spots together and then y’all can see what is actually happening here.

#1 Dead Pixels

Dead pixels are probably the very most common reason you will see a black spot (or spots) on your screen.

Pixels are the individual sources of light that allow your screen to make images.

Well-nigh all pixels today are lit by LEDs. These are semiconductors that come in all shapes and sizes and emit calorie-free.

For your phone screen, the LEDs will emit ruby-red, blue, or green lite.

Other components in the screen will then turn the countless light sources in the screen into the image that you see.

When pixels die, they do non emit whatever lite, then the dead spot will look black while the screen is displaying images.

A lot of things can cause dead pixels. Sometimes they burn out.

More than often, they are damaged by impact or exposure to elements that tin can harm them (like water).

Typically, expressionless pixels don’t spread. If a pixel dies, information technology doesn’t take other pixels down with information technology.

So, if you have spreading dead pixels, it means there’s an additional trouble, which we will hash out a little subsequently.

#2 Stuck Pixels

Now that you know a petty more nearly how pixels piece of work, it might not surprise you to learn that they tin get stuck.

Since other components have to tell the pixels what to do to create an image, those instructions can get messed upwardly.

When that happens, a pixel can stick. It will be the wrong color or off when information technology should be doing something else.

This is most common with liquid crystal displays (LCDs).

The liquid crystals actually tell the pixels what to do, and there can exist communication bug that pb to nighttime spots on the screen.

In one case again, this usually won’t spread over time, but information technology can behave that way.

The good news is that this is one of the easier things to fix, and the solution will be explained in a minute.

#3 Pressure

Speaking of LCD screens, they tin struggle from external pressure.

If you’ve ever pressed on an LCD screen, you probably saw the colors distort and darken under your fingers.

With modern phones, that isn’t a problem because the touchscreen is thick and stiff plenty that touching it doesn’t use much pressure to the LCD part of the screen.

The problem of force per unit area usually comes from the other side.

If something swells or bends on the inside of the phone, it tin can create internal pressure.

That can cause a night spot, and those dark spots are definitely decumbent to spreading.

#4 LCD Components

Outside of pressure level, LCD components tin be damaged and cause dark spots.

In particular, LCDs contain a bunch of tubes that business firm the liquid crystals.

These tubes can break, and so the liquid leaks out. When this happens, y’all’ll meet a night spot on the screen.

More than importantly, the nighttime spot will be at that place fifty-fifty when the screen is off.

This is a discoloration that comes from the leaking tubes, and it means your phone screen is in bad shape.

Besides, the liquid can proceed to spill and expand over time, so this is an issue that can make the dark spot spread across the screen.

four Ways How to Gear up a Spreading Black Spot on Your Phone

Now that you have an thought of what causes the black spot on your phone and makes it spread, we can explore ways to resolve the problem.

Since at that place are dissimilar reasons for the spot to appear, the solutions volition take to match the reason.

And so, we’ll break it down by cause and show you the most reliable options for getting your phone screen back to similar-new condition.

In each case, in that location are DIY and professional fixes.

#1 Repairing Stuck Pixels

Stuck pixels are actually the easiest thing to set up on this list.

The issue is with the digital control mechanisms. That ways you can unstick pixels using software.

You tin go to your app store or a number of websites and look for a stuck pixel repair tool.

It will run anywhere from a few seconds to ten minutes.

What it does is cycle through pixel controllers in order to reset the machinery.

One time everything is reset, the pixels unstick, and the screen works normally once more.

#ii Relieving Pressure

When LCD pressure is the problem, you have to get into the phone to find the source of that internal force per unit area. This means removing the screen.

There are DIY kits and tutorials to follow, but phone repair shops and experts can do this if you are uncomfortable.

Most likely, the pressure is from a swollen battery. If removing the battery stops the swelling, you lot’ve found the problem.

Replace the bombardment, and you should exist fine.

When the battery isn’t the outcome, y’all volition need to look for signs of bent or damaged components that could exist pressing against the screen.

Unbending or replacing those components will salvage the force per unit area.

Sometimes, even afterwards you lot salvage the pressure, the problem persists.

This means that the pressure was enough to damage LCD tubes, and yous demand to perform boosted repairs.

#3 Expressionless Pixels

When pixels are dead, software can’t repair the problem.

Y’all volition need to repair or supersede the damaged pixels.

In virtually all cases, it means you need to supervene upon the screen.

Technically, individual pixels tin be replaced, but they are and so tiny on mod screens that it’south not worth the time and coin to replace single pixels.

The tools and expertise necessary to do that are expensive and hard to find.

On the other mitt, screen replacements are fairly affordable.

You can get a DIY screen replacement kit, or you can have your phone to a repair store.

Either style, the toll of replacing the screen is ordinarily less than replacing the whole telephone.

If your phone is old enough, information technology might be a good justification for an upgrade.

When you supercede the screen, you get rid of the dead pixels, and then the problem is solved.

#4 Screen Damage

When you have spreading black spots, it’due south usually from a crevice or broken LCD tubes.

Even less-common issues almost always involve significant screen harm.

For all of these cases, you are once again looking at a screen replacement.

You lot tin can brand your life easier by checking all of your warranties to come across if they cover all or office of the repair service.

Accidental damage plans are designed for exactly this kind of thing.

Many screen protectors also warranty the screen and volition cover some or all of the repair cost.

Go through all of your potential warranties, and y’all might be able to save a scrap of money.

Why Does the Black Spot Spread?

And then, some causes of nighttime spots are probable to spread while others don’t do it equally much. Why is that?

What is really causing the darkness to motion beyond the screen?

That boils down to a few causes. If dead pixels are expanding across the screen, it means that something is continuing to impairment more and more than pixels over time.

Basically, information technology means your screen is cracked, and the crevice is spreading.

Just similar with a windshield, cracks in glass tin can spiderweb and spread throughout the drinking glass. On a phone, this can lead to more than and more dead pixels.

If the pixels are just stuck, information technology means the control issue is getting worse.

In the case of LCD back pressure level, the force per unit area is increasing over time to spread the darkness.

This almost ever means that the battery is swelling and getting worse (which is much less mutual with new lithium-ion batteries).

In the concluding cause, when LCD tubes break, the released liquid can create pressure within the screen structure.

That tin cause more tubes to break, and you become a domino effect where the dark spot on the screen grows and grows.
