yes hello
if you are stuck focus at short range, please hit the phone on the desk, screen DOWN to the desk. like you want to break the screen. Hit the edge of the screen. It helps if you have a phone case to protect the phone.
LENS DIRECTION:
Lens move OUT(to outside of phone): macro focus
Lens move IN(into the phone, bury inside): FAR focus
so, if it is stuck on far focus, drop the phone on its back
if it is stuck at macro focus, drop the phone on its screen
This fixed my problem
