Question about Samsung Galaxy A33 5G

WifiInfoView shows 72 Mbps in the 2.5 GHz band. Not all the world, but Full HD streaming is possible with plenty of reserve.
With a busy 4G or 5G network, it can of course go much lower.

Sorry,have not used that feauture yet.Would imagine it is as good as any other phone with similar specifications.

Unfortunately I can't answer that, we don't use the phone as a hotspot.

I'm afraid I can't answer that.
