I just got a new 950XL dual sim and I'm not able to see ANY 5GHz wireless networks. Does it not support dual band wireless?
I have found that when I put the phone in airplane mode, and then turn on wifi, it cannot see 5 GHz networks. If I turn on wifi with airplane mode off, then I can see 5 GHz networks. I have seen this behavior sometimes on my Note 5 as well.
