Dead Pixel on AMOLED Screen — Stuck Pixels, Burn-In & Fixes
AMOLED and OLED displays fail differently from LCD. Dead pixels are more dramatic, burn-in is a separate issue, and software fixes are less reliable. Here is what you are actually dealing with.
Quick answer
A dead pixel on AMOLED is absolute black — the organic LED element has failed. Software cycling is less effective on OLED than LCD because OLED does not use liquid crystals. If the pixel shows colour on a black background, it is stuck — try the fix tool for 20 minutes. If it stays black on white, it is dead and requires a warranty or repair assessment.
Test your AMOLED display
Set brightness to maximum. The black screen is the most revealing test on AMOLED — stuck sub-pixels appear as intensely bright coloured dots against true black.

AMOLED vs IPS LCD: how pixel failure differs
| Characteristic | AMOLED / OLED | IPS LCD |
|---|---|---|
| Dead pixel appearance | Absolute black — true zero light output | Dark grey — backlight still illuminates area |
| Stuck pixel appearance | Intensely saturated colour against true black | Colour dot — less contrast vs IPS grey blacks |
| Visibility on white screen | Dead pixels very obvious — high contrast | Dead pixels visible — slightly less stark |
| Software fix effectiveness | Low — OLED does not use liquid crystals | Moderate — liquid crystal realignment works |
| Unique failure mode | Organic material degradation, burn-in | Transistor failure, pressure marks |
| Black screen test | Best test — true black makes defects pop | Less effective — grey glow reduces contrast |
Dead pixel vs burn-in — which do you have?
This is the most common confusion on AMOLED phones. Use this checklist:
Dead / stuck pixel
- ✓ Single fixed dot
- ✓ Appeared suddenly (often after a drop or from the factory)
- ✓ Same appearance regardless of what is on screen
- ✓ Clearly visible in the test tool above
- ✓ Usually covered under warranty
Burn-in / image retention
- ✓ Affects a wider area (navigation bar, keyboard outline)
- ✓ Developed gradually over months
- ✓ Looks like a ghost image of UI elements
- ✓ Most visible on solid grey background
- ✓ Usually not covered under warranty
Fix options for AMOLED pixel defects
Software cycling (low success rate on OLED)
Run the pixel fixer for 20 minutes with the zone over the stuck pixel. AMOLED responds less than IPS, but it is worth trying before other steps. If the pixel shows colour on black (stuck), there is a chance of recovery. If it is dead (black on white), software will not help.
Do not use the pressure method on AMOLED
Physical pressure can permanently damage OLED panel layers. The pressure method is for LCD only. Never apply pressure to an AMOLED phone screen.
Manufacturer tools (OLED-specific)
LG OLED TVs include a built-in Pixel Refresher that runs a compensation cycle. Some Android manufacturers (Samsung) have display diagnostic modes accessible via service menus. These are manufacturer tools — use only if you know what you're doing.
Warranty or repair
A dead pixel from a manufacturing defect is covered under warranty. A pixel that appeared after a drop or physical impact is not — a screen replacement from a certified repair shop is the only fix.

Frequently asked questions
How does a dead pixel look different on AMOLED vs LCD?+
On AMOLED, a dead pixel is absolute black — true zero light. On IPS LCD, it is dark grey (backlight still illuminates the area). Stuck pixels on AMOLED are also more dramatic — intensely saturated colour against true black.
Why is software pixel fixing less effective on AMOLED?+
Software fixers work by cycling colours to realign stuck liquid crystals — an LCD-specific mechanism. AMOLED uses organic LEDs, not liquid crystals. Software cycling can sometimes trigger an unstick but success rates are much lower than on IPS.
What is the difference between a dead pixel and burn-in on AMOLED?+
Dead pixel = single fixed dot, appeared suddenly. Burn-in = ghost image of static UI across a wider area, developed gradually over months. Dead pixels from manufacturing defects are usually under warranty; burn-in usually is not.
Which phones use AMOLED displays?+
Samsung Galaxy S/Z series, Google Pixel 6+, OnePlus 12/13, Xiaomi 14/15, Apple iPhone Pro models (OLED). Most premium phones since 2019 use OLED/AMOLED.
