Black dot on phone screen
A single small black dot on a phone screen is one of three things: a dead pixel (a sharp black point on every colour), a speck of dust under the screen protector or the glass (raised, and it moves with the protector), or the start of pressure damage (soft-edged, grows over time).
Test it now
Full-screen white, then red, green and blue. Dead pixel: black on all four, exactly one pixel size. Dust: peel back the protector corner and look. Pressure: soft edge, larger than a pixel.
What it is
A single small black dot on a phone screen is one of three things: a dead pixel (a sharp black point on every colour), a speck of dust under the screen protector or the glass (raised, and it moves with the protector), or the start of pressure damage (soft-edged, grows over time). A dot near the top of the screen on many phones is the proximity sensor or the front camera cut-out — not a fault.
Can it be fixed?
Dust: yes, clean and refit the protector. A stuck pixel (wrong colour rather than black): sometimes, with the pixel fixer. A dead pixel or a pressure dot: no — but a single dead pixel is not worth a display replacement; it is worth a return if the phone is new.
What to do
- Colour test to classify it.
- Check the screen protector.
- Stuck pixel: fixer for 15 minutes.
- New phone with a dead pixel: return it within the return window rather than claiming warranty.

Warranty
Most makers replace a panel under warranty for physical panel faults that are not accidental damage; pressure marks, cracks and liquid damage are treated as accidental and are not covered. For dead pixels, each brand has a threshold (typically 3–5 bright or 5–8 dark pixels on a laptop; Dell's premium-panel guarantee replaces at one bright pixel).
