Good Tizen phone with 1.3GHz Quad-Core processor provides good performance and great system execution of the Samsung Z3.
An advantage of the Samsung Z3 is the possibility of using two mobile carriers, a Dual-SIM device with two SIM card slots.
Good connectivity of this device includes Bluetooth 4.0 + A2DP, WiFi 802.11 b/g/n (2.4Ghz), but it lacks NFC connection.
