Weird noise in calling
I've had M8 for one week now. It is an amazing phone. The only issue is during out-coming calls, some random noise (beats) happens. The beats are so strong and you can hardly ignore them. I am using unlocked M8 bought from HTC website, not sure this is a common issue or just my phone. I've never had this issue before with my other phones (HD2, S3, note 2).
