Your action plan for a glitchy screen:

Stop downloading sketchy "screen fixer" apps from the internet. Your Samsung phone already has the most advanced diagnostic suite on the market. You just need to know where to tap. Save this guide—your future self will thank you when your Galaxy falls face-down on the pavement.

Disclaimer: The *#0*# code works on 99% of Samsung Galaxy devices (S series, Note series, A series, Z Fold/Flip). If the code does nothing, your carrier (Verizon, AT&T, etc.) may have disabled it. Use the Samsung Members app instead. AMOLED burn-in (ghost images of keyboard or TikTok

Imagine you’ve just bought a secondhand Galaxy phone from a stranger in a coffee shop. It looks perfect, but how do you know if the screen has hidden "dead" zones or if the sensors are actually firing? This is where the Samsung Galaxy Diagnostics Tool—a "secret" menu used by technicians—becomes your best friend. The Hidden Gateway: *#0*#

Most users never see this screen because it’s tucked behind a "magic" code. When you open your phone dialer and type *#0*#, the standard interface vanishes, replaced by a grid of clinical white buttons.

This isn't just a menu; it's a raw hardware interrogation. Technicians use it to bypass the flashy software and talk directly to the phone's physical parts. The Story of the "Ghost" Touch

The most dramatic part of this tool is the Touch Test. When you tap it, the screen turns into a grid of empty squares.

The Mission: You must trace your finger across every single square to turn them green.

The Reveal: If you find a square that refuses to change color, you’ve just discovered a "dead zone"—a physical hardware defect that standard apps might hide. This "exercise" ages the less-used pixels to match

The Exit: The test is so strict that you often can't even exit the screen until every single square is green, proving the digitizer is 100% functional. The Color Interrogation

The tool also features Red, Green, and Blue buttons. Tapping these floods the entire display with a single, pure color. It’s the ultimate test for:

Dead Pixels: Any tiny black or white dots that shouldn't be there.

Screen Burn-in: Ghostly shadows of old icons that haunt the display. Modern Alternatives: Samsung Members
