Symptoms
- Original crack lines lengthen over time
- New spiderweb lines branch off the original crack
- Crack grows faster with pressure or temperature changes
- Touch may still work despite the spreading crack
Likely causes
- CommonOngoing pressure on already-weakened glassNormal handling, pocket pressure, or a case can keep stressing a crack until it spreads.
- CommonTemperature changes stressing the glassHeat and cold expansion/contraction can slowly widen an existing crack.
- PossibleAdditional minor bumps adding to existing damageSmall everyday knocks can extend a crack that's already there.
What to do
- Cover the crack with clear tape or a screen protector to slow spreading and contain glass shards.
- Avoid pressing on the screen, especially near the crack.
- Keep the phone out of extreme heat, like a hot car, which can worsen glass cracks.
- Use a case with raised edges to reduce pressure on the screen from drops or being set down.
- Back up your data since a spreading crack increases the risk of the screen failing completely.
- Get it repaired sooner rather than later, since the cost and risk generally only grow.
