iPhone Screen Test

Use this free iPhone screen test to check for dead pixels, touch problems, color issues, and OLED burn-in. It works in Safari or Chrome with no app install.

This page uses easy wording so anyone can follow along. You do not need special skills. Look at the screen, tap where needed, and note what looks wrong on your iPhone.

This page is useful before buying a used iPhone, after a screen replacement, or before a trade-in. A quick visual check can catch problems a single photo often hides.

What you can check

What this iPhone screen test helps you find

A cracked glass is easy to see. Many costly display faults are not. These simple checks make dead pixels, touch faults, tint, and burn-in easier to notice.

Dead and stuck pixels

Solid color screens help you spot black dots, white dots, or tiny always-on color spots.

Touch and multi-touch

Tap and swipe across the whole display to find dead zones near the edges and corners.

Color and white balance

Look for yellow patches, pink whites, or uneven color on the OLED panel.

Brightness and black levels

Dark screens show clouding, light leak, and weak blacks more clearly.

OLED burn-in check

Watch for faint keyboard, status bar, or icon shadows that stay on the screen.

After drop or repair

Retest if the iPhone was dropped, got wet, or had a screen replaced.

Easy steps

How to use this iPhone screen check

Clean the display. Dust and fingerprints are often mistaken for dead pixels.
Use a darker room for black tests. Backlight bleed and burn-in show up better in low light.
Use normal light for color tests. Bright windows can hide tint problems.
Cover every edge in the touch test. Corners and camera cutouts fail first after drops or repairs.
Write down what you see. Note dead pixels, dead zones, tint, glow, or image shadows.

Common issues

Common iPhone screen problems

People search for a iPhone screen test, dead pixel checker, touch screen test, and OLED burn-in test for the same reason: a bad display can ruin an otherwise good device.

Dead pixels

A tiny fixed black or white spot that does not move when you wipe the glass.

Ghost touch

The phone taps by itself or misses taps after a bad digitizer repair.

Yellow or pink tint

Uneven white or warm patches can mean a weak OLED panel.

Image retention

Faint outlines of apps or keyboards that linger on gray screens.

Why it matters

When you should run a iPhone screen test

Before buying used

Sellers can hide faults with bright wallpapers. Solid color screens make defects obvious.

After a drop

Touch can fail even when the glass still looks fine.

After screen repair

Confirm the new panel has no dead pixels or dead touch zones.

Before selling

Know the real condition of the display before a trade-in.

Is this iPhone screen test free?

Yes. You can use this page for free in your browser. No account is needed for a basic display and touch check.

Do I need to install an app?

No. Keep it simple and use your browser. That makes testing fast on almost any iPhone.

Can I find dead pixels with this page?

Yes. Solid color screens are one of the easiest ways to spot dead pixels, stuck pixels, and hot sub-pixels.

Does this work for OLED and LCD?

Yes. On OLED, also watch for burn-in. On LCD, watch for backlight bleed and cloudy blacks.

Is this a professional hardware report?

No. It is a practical visual and touch inspection. For final repair decisions, a technician may still need to inspect the device.
