- Otherwise normal photo quality apart from the speck
Likely causes
- CommonManufacturing defect letting in a particleRarely, a speck of dust gets sealed in during assembly.
- PossibleDebris entering through a crack or gap in the lens housingA drop or damage can create a small opening that lets dust in over time.
- PossibleDebris from a previous repair with the housing not properly resealedIf the phone was serviced before, a poor reseal can allow dust in.
What to do
- Confirm the speck is beneath the glass by trying to wipe the outer surface first.
- Check photos to see how visible the speck actually is in typical shots; it may be more noticeable up close than in normal use.
- Note if the phone has a history of drops or previous repairs.
- Avoid trying to open the lens assembly yourself, since this is a precision, sealed component.
- If it bothers you or affects photo quality noticeably, have a professional inspect and clean it.
