While calling isn’t a huge priority for every smartphone owner, plenty of folks do still regularly make calls with their pocket computers. Ray’s description of these issues as “intermittent” suggests that your calls may not have any issues, but still, this is something to keep in mind if you make any phone calls today.

Are you having any calling issues today?
