I was having this issue intermittently at first but now I can't get my 2nd screen to work at all in dual & extended mode, but works just fine in Mirror.
Definitely confusing and more so frustrating as those are the most important modes to this phone and main purpose of the 2nd screen.
The screen will function in the mirror mode (A/A) but it won't give me the option to select the other two modes at all.
Anyone else run into this before? What can I try to fix this issue?
Someone please help.
