========================================
Everytime I call someone on the phone I can't use the mobile data to search something in the internet at the same time. So as far as I know to avoid this problem VoLTE has to be active, so how can it be activated on the phone?

I think asus have to activate it for each Carrier.....

It's very easy to activate but you require ROOT.

They just released an update for the ROG Phone 3 which enabled VoLTE for T-Mobile & AT&T so it could potentially be in the pipeline for the ZF7 as well
