Can't record calls like the older application. Also, there is no option to dial from the carrier of choice when a phone is dual sim supported, although we can swap the sim after the call is placed. It would be helpful to have that option before dialing in a scenario where , say, carrier 1 has no network and it is set as a primary carrier for outgoing calls , and your call is hung up even before you could tap the swap icon. I hope I have explained well enough.
