A new Samsung smartphone has received Bluetooth certification from the Bluetooth SIG. The listing reveals the device carries a model number of SM-C7100. Given that the Samsung Galaxy C7 from last year carried a model number of SM-C7000, it's reasonable to assume that the SM-C7100 is the successor to that device. In addition to the SM-C7100, two other variants - the SM-C7108 and SM-C710F - have also received Bluetooth certifications. Source | Via
