So I got my Z2 and am loving it so far. No problems that really take away the experience of using this amazing phone. However, does anybody else notice that the phone switches from LTE 4G to H+ during a phone call? The switch happens instantaneously and it's hardly noticeable unless you're looking at the screen. Whenever I am on a call, my phone switches to H+ rather than staying on 4G. I only noticed because I tether my laptop and the speed on my laptop suddenly dropped during calls.
