Why this distinction matters
Many customers come in saying “I just cracked the glass” expecting a cheap glass-only repair — and are surprised when the technician recommends a full assembly. Understanding why helps you trust the diagnosis and compare quotes accurately.
Glass-only repair
What’s replaced: The outer Gorilla Glass or equivalent protective layer only
Cost: Lower — typically $30–$80 less than a full assembly
Time: Longer — the glass must be carefully separated using heat and suction tools
When it’s appropriate: Only when the glass is cracked but the display underneath still shows perfectly — no dead pixels, no touch issues, no discolouration
⚠️ Important: Glass-only repair is not available on all phones. Curved screens (Samsung S-series) are significantly harder to separate safely. Always confirm your screen type before agreeing.
Full assembly replacement
What’s replaced: The entire screen module — glass, digitiser, and display panel as a single unit
Cost: Higher — but includes a fully new display
Time: 30–60 minutes for most models
When it’s required: When the display is damaged (lines, dark patches, touch not working, black screen) — or when glass separation risk is too high
How to assess your own damage
| What you see | Likely repair needed |
|---|---|
| Cracked glass, display shows perfectly, touch works | Glass repair may be possible — technician must assess |
| Cracked glass with dark patch or bleed spreading | Full assembly — display is damaged |
| Lines or dead pixels on screen | Full assembly — display panel is damaged |
| Touch not responding in areas | Full assembly — digitiser is damaged |
| Completely black screen after drop | Full assembly (or connector issue — technician must check) |
| Glass cracked on curved Samsung S-series | Usually full assembly — curved glass separation risk is high |
