Hello, sorry for my bad english I'm french. I've recently bought a Meizu 16th global version. At first sight all works very well. But few days later I've seen Many bug on my device. First of all my sim card bug and she's not detected everytime. Now I've found a solution (erase data of qualcomm names program) but After that I can't receive or call, there is a Sim Error. The second is the wifi, one times it works 2 sec After It bug. The third is the Bluetooth when I turn on and After lock my device I can just swap sounds and it's impossible to unlock device. If you have solution or anything for help me I'll take it. I've bought my Phone on lightinthebox and I'm not sure I can return the device.Thank You have a Nice day
