I play fortnite on my cell phone, I can also hear my friends but they haven't looked at me in the settings, I've tried everything with and without headphones
Times reset your sound settings
Maybe you had Push to Talk on I too
No I have not
Did not work
You also need a headset;)
I tried it with a buddy today and it didn't work either
No you don't need it. I used to play on my cell phone without a headset
