Same here. Ever since the 4.2.12 updates, I had not been able to get FCC mode with Floater.I'm posting this here, as it may be related to the Go4 updates, chastise me if you think not guys.
I've been trying 'Floater' to set FCC for just those difficult situations when 300m range isn't good enough.
Firstly, maybe I'm doing something wrong but, it seems to take several attempts to get the 11 channels to confirm FCC, Sparky seems to want to stay in CE, even when Floater is running and set to 'somewhere else'.
Second, when I do manage, after several attempts, to set FCC, I can only do it with an OTG connection. If I set FCC and then restart the RC/Go4/AC with no OTG connection, it reverts to showing 13 channels without ever asking me to confirm.
I then have to do it all over again several times with an OTG connection to get FCC to take, it seems.
I've used a whole battery today, just trying to figure out what I'm doing wrong, because last night I set FCC, then closed everything down including Floater. This morning when I fired her up without OTG, I had 13 channels again.
Is this possibly something to do with the app versions, I'm currently running 4.2.14.583?
My only thought is that on my Samsung s7 edge, there is a developer setting that says 'select mock location app', which I tried setting to Floater, but I can't and it always set to another different app. This is my only thought
