It says im not enabled to use vc, I've tried both ways via options and it crashed my game.

What mobile device are you using and what version of Android?

I am using the kindle fire hd, 7" tablet..manufactured in 2013.

1st version of the fire hd series I believe

Both ways? which ways are those?

1st way, I went to advanced options>game> voice chat
It said I am not enabled too use it.

2nd way, I went to advanced options>vc
The result was the game crashing.

I only wanna enable vc.

Sorry. I posted this same question on the General forum. Just saw this post now.

I have a Samsung S7 and cannot enable voice chat. With the upcoming VR release for Gear VR, voice chat will be nearly mandatory for any sort of communication since typing will be all but impossible.

I haven't in months but I have used voice chat on kindle fire hd 7" before.

Edited to add:
I tried last night and I could not enable vc.
