Dead Pixel Fix Tool for Phones
Rapid colour cycling to unstick stuck pixels on iPhone and Android. Run for 10–20 minutes.
Rapidly cycles colours to unstick stuck pixels on iPhone and Android. No download needed.
How to Fix a Dead Pixel on a Phone
First, confirm you have a stuck pixel, not a truly dead one. A stuck pixel shows a persistent wrong colour (not black) — it can often be fixed. A dead pixel is permanently black.
- 1.Run the fix tool above for 10–20 minutes with brightness at 50–70%.
- 2.Check the pixel using the test tool.
- 3.If still stuck, try the pressure method below.
- 4.If the pixel is truly dead, proceed to a warranty claim or screen repair.
Does It Work on AMOLED Screens?
Rapid cycling can revive stuck sub-pixels on AMOLED, where the organic emitter is still functional but stuck in one state. True dead pixels on AMOLED — where the organic material has burned out — cannot be fixed by software. If you have a bright coloured dot, try the fix tool. If you have a black dot, it is likely a dead pixel and needs hardware repair.
Manual Fix Methods for Phones
Gentle pressure method
Power off the phone. Place a clean microfiber cloth over the screen. Apply very gentle pressure with a fingertip (not a stylus or hard object) over the stuck pixel for 10–20 seconds while powering the phone back on. This can sometimes dislodge a stuck pixel transistor on LCD screens. Use extreme caution — too much pressure will cause more damage.
Temperature method
Slight warmth (e.g. leaving the phone in a warm — not hot — room) can help on LCD screens. Do not heat AMOLED screens — heat accelerates organic emitter degradation. Never use a heat gun or hair dryer directly on the screen.
Software apps (Android)
Several Android apps cycle colours at higher frame rates than a browser tool. Search for "dead pixel fixer" in the Play Store for options — the principle is the same as this tool.
When to Stop and Claim Warranty
If the fix tool and manual methods have not worked after 30 minutes total, the pixel is most likely permanently dead. The next step is a warranty claim. If the dead pixel appeared without physical damage, it is likely a manufacturing defect and is usually covered.
Frequently Asked Questions
Does the dead pixel fix tool actually work?
It works on stuck pixels — pixels stuck in a wrong colour state. Rapidly cycling colours forces the pixel transistor to switch rapidly, which can jolt it back to normal. True dead pixels (hardware failure) cannot be fixed this way.
How long should I run the fix tool?
Run it for 10–20 minutes for best results. If the stuck pixel has not recovered after 30 minutes, it is unlikely to recover with this method.
Does it work on AMOLED screens?
Partially. Stuck sub-pixels on AMOLED sometimes respond to rapid cycling. True dead pixels on AMOLED have burned-out organic material and cannot be fixed by software.
Will the fix tool damage my phone?
No. It only changes the screen colours rapidly — there is no risk to the hardware. The tool uses standard browser rendering, no system-level access.
What do I do if it does not work?
Try the gentle pressure method (see below) or a temperature change. If neither works, the pixel is truly dead and a screen replacement or warranty claim is the only fix.
