I have an s20+ 5g and went to an intersection that has 5g and my phone showed as 5g but when I ran a Speedtest it showed only lte. Anyone else have this problem?
Many of the 5G networks are still in the updating and propagating, and not all 5G is actually up to the true 5G standards, yet. It's too early to consider this a fully functional setup yet. There's a number of reports similar to yours out in the wild right now, so don't get too worried just yet.
