I have some issues with my Note 9 camera. When i zoom in the picture gets blurred and i can hear a motor or the lens from the Camera. Tried everything including resetting the phone. Anyone knows anything about this issue.
I had the same issue a while back, it's a hardware issue, you'll need to take it to a Samsung Service Center to get it fixed. As temp fix until you get it repaired, when you zoom in and it goes blurry and makes that buzzing sound, hold the phone tightly in your hand and give it a good shake, that will sometimes get it to focus.
Hopefully you have a Samsung Service Center in your area or you'll probably have to send it in.
Strangely, i installed the google camera apk (modified) to get night sight and some google goodies. One day, i'm switching back and forth for comparison between the main camera app and the google apk app ... Boom, i hear the camera trying to zoom, there's a waving effect and i'm sitting there like what happened to my phone. Play with the bug, reboot the phone, kill the apps for a day. Nothing. Until i uninstall the google apk camera, wiped the cache from the main camera app and rebooted. Everything back to normal... THE MOST STRANGEST thing ... never came back to it's broken state... go figure what really happened. I think i can reproduce since i know exactly what i did and what mode i was in but ... meh ...
