Hello,
I contacted my phone provider because I have a 5g subscription but my Fairphone 4 could never connect to 5G.
They check the connectivity at my location and said I should receive it but after checking my phone model they told me that it’s a bug on Fairphone side; 5G is supported but the icon is not properly showing up. Here is their internal note screenshot:

Any other user with that experience ? How can I check that I am actually receiving 5G signal?
