My Galaxy S5 makes noise when shaking the device

Last Update Date : Apr 23. 2018


:When shaking my Galaxy S5, it makes strange noise within inside of device. What’s the sound?




:It’s not device faulty but normal operation.
It’s the sound which happens in Lens Barrel to operate the Auto Focus function, and it’s also same operation applied to existing other devices.

Your Galaxy S5 support the Auto Focus feature for high quality and high resolution of camera.
At inside of Camera module, there are Lens Units of16MP and Image Sensor, and Auto Focus feature adjusts focus by moving Lens Units to up and down direction on above Image Sensor.
This operation of type is good to not only Auto Focus speed and accuracy but also reduce battery usage.

But it need the minimum spaces for movement of Lens Units to adjust focus, and additionally there is Stopper part
which fix to be able to move this Lens Units within permitted limited space.
While the Lens and Stopper are touched when shaking the Galaxy S5, the minute noise may make and it’s normal operation for work of Auto Focus feature of camera. The sound may differ by device types and model.
