Hi,
This is my first post here, wiieeeee!

I have a Meizu Pro 5 Chinese model.
It worked just fine and I was happy with the phone, but then it stopped receiving incoming phonecalls.
It just went direct to voicemail, and I get a sms showing i got a missed call.

I have done factory reset but it doesn't help. I can receive 1-2 calls and then the 3rd call is going to voicemail.

How can I fix this?

Please help me! Thanks.

Regards
Brokkoly
