There is another bug... After Volte came.. no apps could be download from play store ... If u uninstall updates... Volte will go...

Glad it worked out..

It is not system update... So no use checking in system--> updates..

I'm using jio sim... I removed it... And put airtel sim... As soon as I did it... I got update..... I did it and waallaaa... Wifi calling and volte...So I highly recommend u to do it.. many got fixed like this..

How did you get this update.. any sets to be followed?
