I have an Xperia Arc handset. I tried making a call through Viber. It works fine on loudspeaker and the in-built speakers of the phone but when I tried using the original handsfree that comes with the phone, I can hear my friend clearly but my friend can barely hear me. Does anyone else face this issue or it is a hardward failure?

Yeah, I just came across the official viber thread. Thanks. I tried the sonic gear earpump headset and it solves the problem. But then I am using the phones built-in mic. As for the original headset, I tried using it to call dirently and it works just fine. Even for line also the volume is loud and clear. But for viber its very soft even on maximum in-call volume.

Apparently I think there is a bug while using Viber on Xperia Arc. I can hear the opposite side loud and clear but they can barely hear my when I am on handsfree. The handsfree works just fine for direct calls. Anyone encounter this? Xperia Arc users?
