Black dot in screen

I had vertical white line with black smudges on either end of white line. Moto returned phone w/o repairing. Only 3 months old

Possible causes of a black dot on your screen:

• Broken screen → Unfortunately not repairable with software (these dots are usually bigger and irregular).
• Dead pixel → Permanently black, very small, and can’t usually be restored.
• Stuck pixel → Appears as a tiny dot that stays on one color. This is the only case that can sometimes be fixed.

👉 For stuck pixels, the good news is that free tools like Pixel Fixer can help. It uses rapid color changes that may reactivate the pixel.

I especially recommend trying the Magic Thumb Tool inside the app — it combines gentle pressure with rapid on-screen flashing, which is one of the most effective ways to revive a stuck pixel.

⚠️ If the app doesn’t work, you can also try using a soft eraser or cloth to massage the pixel gently. But be careful: if it’s a broken screen, pressing too hard can make it worse.
