No incoming calls when mobile network is ON

Hi guys,
I just bought Mx4 pro a week ago which started giving bad heating and battery drain issue. Therefore I upgraded to from But same issue remains. (I did clean installation)

I figured out that it only happens when my mobile network is turned on AND found out there is no incoming call during that time.(outgoing calls work)

Please suggest a solution.

Did you try to clear data manually from Apps menu in system settings? You should try to do this for all applications that somehow connected with calling (e.g. Phone.apk etc.). Of course where is it possible.

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
