Symptoms
- Crack radiates outward from one corner
- Rest of screen still displays and responds to touch
- Crack lines grow slightly over days or weeks
Likely causes
- CommonCorner impact concentrated force on a small areaCorners have the least glass support, so cracks start there most often.
- CommonNo case or a thin case at time of dropCases with raised edges absorb corner impacts and prevent this.
What to do
- Apply clear tape over the cracked area to stop shards from lifting and to slow the crack spreading.
- Avoid pressing on that corner or setting the phone face-down.
- Back up your photos and data soon in case touch response degrades.
- Add a shock-absorbing case with raised corners to prevent it from getting worse.
- Get the screen replaced before the crack reaches the display's active area and causes dead pixels.

When to call a pro
See a repair shop before the crack spreads to the display area, which turns a glass-only repair into a full screen replacement.
Safety
Use caution
Glass can flake off the crack edges; avoid rubbing the area with bare fingers.
