My S6 was perfect the when it was lollipop, but when I updated to Marshmallow since that very moment I cannot make online Internet calls in apps like WhatsApp, Skype, Kakao, Line, WeChat, Messenger. But I can make normal calls on my carrier network.
I have tried calling from other Internet connection networks but it's the same.
It's like when I cannot someone online, after they receives my call, it is connected for 5-10 seconds and then it gets disconnected or it shows reconnecting and it never connects. Then again if I call, it's the same.
Can you give a solution to it?
My phone's current OS version is G920FXXS3DPB2.
