The fingerprint scanner only works about half the time and the phone restarts frequently. Should I try to fix this (and how) or get a new phone, and if so, which one? I was thinking of getting something used on black market phone. I use Verizon
I'm going to assume you didn't mean an actual "black market" phone (which would be illegal and risky). You can find plenty of used phones on legitimate sites like eBay or Swappa.
