Apparently, apart from suffering from severe manufacturing defects such as the SIM tray not working properly, exceptionally low screen quality for a smartphone which is supposed to have Gorilla Glass 3, troubles with the microUSB port, and unusually high overheating issues, the phone is also suffering from some serious software bugs, such as contacts mysteriously not showing up when accessed through the dialer app, and several other complaints of unstable software and random WiFi/cellular signal drops.
