Yes 1 example on how I used both at the same time on a regular is with Telenav/Maps/TBT. Telenav/Maps/TBT feature uses data correct? Well I have used that while talking on the phone numerous times. I have also conducted numerous calls to companies while on their website discussing acct info while on the go. When I say I used it on the regular that is an understatement. So I have a BIG problem now with not being able to. Is there no resolution to this problem now? Considering I was able to just a couple days ago? Can I roll back the update?
As far as TeleNav, when talking it will be offline and the app itself will still track your car's movement and gives turn by turn direction from the already stored information. I have tried that before and it will not update maps once it goes past the stored info.
Also, once you have accessed the page, it will still stay loaded and you can look at the page, but technically you would not be able to move out of that page while in a call.
Again, I'm not sure how, but since the S4 Triband, none of the Samsung devices was able to do Voice and Data simultaneously.
Humm not sure about that with TeleNav, because I have held entire conversations, hands free that is, while using TeleNav and made it to my destination. It would pop in to give directions and the person I'm on the call with could hear it to. But, anyway am I able to roll my last update back?
