I have had my phone for 2 weeks and I have been using the 5GHz network on my router today it's dropped me from the network and now fails to connect and cannot even see the 5 gigahertz side of it. It can see and connect to the 2.4 gigahertz network but I don't want to do that. Just out of interest I set up a Wi-Fi Hotspot on the Blackview and picked 5 gigahertz to transmit on, looking on my Chromebook's WiFi Analyser I can see that it is in fact broadcasting on the 2.4 gigahertz network system instead.
It would appear to me that the 5 gigahertz chip or whatever it is has stopped working.
I have factory reset it and it is still the same it cannot see my 5GHz network.
I have reset my router multiple times and even manually configured the channels to see if it had gone to a channel that the Blackview cannot see and I still cannot get it to work.
I have less than two weeks to solve this problem otherwise I'll have to return it via Amazon as that is the only amount of time I've been allowed.
