Symptoms
- Clicking, buzzing, or grinding sound when opening the camera or focusing
- Sound is noticeably different from normal quiet operation
- May be accompanied by shaky or failed autofocus
- Sound might occur only when the phone is held in certain positions
Likely causes
- PossibleNormal lens-shift stabilization movement (usually very quiet)Some phones make a faint, barely audible sound during stabilization or focus, which is often normal.
- CommonDebris inside the camera module interfering with the focus mechanismA small particle can cause a grinding or clicking sound as the focus motor tries to move.
- PossiblePhysical damage to the focus motor from a dropImpact can bend or dislodge the tiny mechanical parts that move the lens for focus.
What to do
- Listen carefully to judge if the sound is a very faint, consistent click (often normal stabilization) or a loud grinding/rattling noise (likely a problem).
- Restart the phone and test the camera again.
- Gently tap the back of the phone near the camera (without excessive force) to see if it dislodges minor debris.
- Check if autofocus quality has also degraded alongside the noise.
- Note whether the phone was recently dropped.
- If the sound is loud, worsening, or paired with focus problems, get it checked by a professional rather than continuing to use it.
