Translating step 3
Interestingly, Samsung chose to stay with a run-of-the-mill micro USB port, instead of the new USB Type-C standard.
For now, Samsung seems to think that the older, more widely compatible standard is good enough.
Samsung has also made upgrading to a new phone incredibly easy, with an included USB adapter. It's almost like they expect you to buy a new phone before your current device is completely worn out beyond repair. Weird.
