When I zoom in, my phone vibrates like it's receiving a call on vibrate and lasts a long time. I believe it is coming from the camera lens motor to adjust the aperture.
I tried it in different lighting too, and I even reset camera settings, but it did not work.
It has been vibrating before, but not as much, so I thought it was normal. Now it is vibrating for literally 25 seconds straight. I'm sure that's not normal. It's pretty loud too; it sounds like a battery powered shaving razor.
Live focus doesn't work either. I've done all suggested troubleshooting steps.
bought this phone brand new (pre-order) factory sealed from samsung portal
