Well, this might be obvious that everyone in the Windows phone platform has had numerous problems with WhatsApp and it's lack of options compared to their Android and iOS counterpart. I today have a new bug to present . A faint sound in the speaker when that particular app is open. I don't know if it's just my Lumia 620 or everyone had this problem but weren't aware of it. It just feels awkward to hear that sound. (it feels like they are recording everything but a bug made the speaker sound off). Do you guys have this problem or am I just hearing stuff?
