Symptoms
- Lid pops back open instead of staying closed
- Hinge feels loose or wobbly
- Lid doesn't sit flush when closed
- Case doesn't charge properly because the lid isn't sealing
Likely causes
- CommonDebris or lint caught in the hinge mechanismSmall particles can prevent the lid from closing and latching fully.
- CommonHinge spring or latch mechanism worn from repeated useCases opened and closed many times per day can wear out the mechanical latch over months or years.
- PossiblePhysical damage from being dropped or sat onImpact damage can bend or crack the hinge or lid frame.
- PossibleWarped plastic from heat exposure (like being left in a hot car)Heat can warp the case's plastic enough to affect the lid's fit.
- Less commonManufacturing defect in the hingeSome units may have a factory defect in the latch mechanism.
What to do
- Inspect the hinge area closely for any visible debris, lint, or sand and clean it out with a soft brush or toothpick.
- Test if the lid closes properly when pressed firmly versus just resting shut, to gauge how worn the latch is.
- Check for any visible cracks or warping in the case body, especially if it was recently dropped or exposed to heat.
- Avoid forcing the lid shut if it feels like it's catching on something internal, which could cause further damage.
- If the case is still under warranty, contact the manufacturer, since a broken hinge is not user-repairable.
- As a temporary workaround, some people use a small rubber band around a case to keep it shut, though this doesn't fix the underlying issue.
