Yeah, I've been experiencing similar issues, especially with B41. The device is constantly switching to different bands in strong B41 signal areas. At times I've lost LTE all together, it almost seems like it doesn't know what to do lol. I tried the Z2 for a few days before I decided to switch back to Sprint and the difference between the two, RF wise is like night and day. I decided over the V30 figuring it would be equal or close to the Z2 RF wise, but so far it hasn't. I'm talking about a solid 10 dbms better in signal. Very disappointing. I think I rather have the Z2 Force although it doesn't have 4XCA and 2xCA on upload but it holds a great signal, aside from the fact that it is cheaper than the V30.
