I have not bought one yet and wondered if the Navigation continues while on a call with Verizon's 5 or will it cache enough of the map to keep you on course while on the call. I travel a lot for work and use my phone for navigation in rental cars. Presently I have an HTC Rezound and would like to switch, but the way the Verizon version handles LTE has me concerned. I am already bummed about not being able to do voice and data when I can do it on my Rezound even in 3g. I want to get back to the iPhone but not sure if this is the time or not. Thanks
