I went back and exchanged my One S for a new one. The person at the counter backed up all my contacts to the SIM card before switching me over. Now that I'm running on the new phone, it seems all my contacts were synced to my google account, and now I have a bunch of duplicates in the SIM card. I can't find a way to delete them off the card though. I downloaded an app but it didn't actually delete anything. Is there a setting I'm missing or something?
