I use two SIM cards in my phone. Sim 1 is Telenor and Sim 2 is Mtel. When I turn on mobile data on Sim 1 everything works fine, but when I turn on mobile data to sim 2 then Sim 1 can only receive one call and later I can no longer receive calls to sim 1. Once I turn on mobile data to sim 1 all good again it works. I noticed this problem in more people who also has this Mi 2 phone. This is a software error. Will it be an official update to correct this error?
