How common is the camera rattle?

[Androiduk2016]

I've read a few concerning reports that people's camera results? As if there's a loose piece in it.

How many people has this happened to?

This camera can rattle by design. When motor closes the camera it is relatively tight until you place zenfone in a loose pocket and start moving or put down a few times on a solid surface. Then it gets loose and starts rattling. In that case you can light up your screen and tap the camera housing a few times (it will retract automatically) or click power button a few times (every time it corrects a bit). For sound dampening effect I've placed a bit of insulation tape into the hole, however it certainly will rattle from time to time. I hope it won't get worse after a year or two.

i am not sure why people are forcefully trying to shake their device just to see if it rattles. for me it doesn't unless u shake it with extreme force and why would somebody do that. as already pointed by @ColorSage if you think its completely loose there are ways to get it back in the correct position.

Mostly it's fine. Very rarely does it rattle but I just click retract camera option and it's fixed.

Like others said, it's just how it's designed.
