camera autofocus

[louis14]

I have a galaxy A3 2017,
the autofocus of the camera does not work at for example 30 cm or 2 meter,
if i shake the Phone before i take a photo: it works!
Isn't there a setting to wake up the autofocus?

Does the camera module make any strange noises when you try to focus? Does it sound like it's grinding or stuttering? If so, the autofocus mechanism might be jammed, which would require repair. Is the phone still under warranty?

I had contact with the technical support of samsung and we have done a test i have called *#0*# and then choose the camera: this is a hardware test of the camera: here works the autofocus: this means an external app influence my camera app.And yes i have found the app and removed that app.The app is called "nowjobs".Now my autofocus works correctly!
