hii using PRO 7-H (792Q) Chinese Version 6.3.0.0 A
(* written by Translator. sorry bad english)
if i try to answer the phone, when WI-FI is connected.

I can't hear the other person's voice well.
But when i disconnect from Wi-Fi .
Then i receive the call again, i can hear the other person's voice well.
By the way, i use KT(케이티) which is Korean communication company.They support  (3G & 4G both)
Wait for any answers.

Thanks & Best regards.
