The USB-C connector on the Model 3 is a little too short for many phones that have a thick case. I've seen replacement cables offered that provide a plug that sticks out more. However, I was able to implement an easy fix thanks to this video:
Skip ahead to 2:42. Basically, take a little piece of cardboard or folded paper and wedge it under the connector. It will raise it enough to fit into the phone's port.
