i just got my nexus 5 and im so sad of how crappy its making me feel about purchasing it, im having low audio during calls and when i record video, i can hear hissing and audio interruption, and my power button is a lil loose and when i tap the top area of the screen i can hear the button shaking as if it was a 500 dollar toy, now they just released and update to android 4.4.1 and its slowly rolling out to the phones any day now, but it doesn't say if it fixes the audio issues it only mentions the camera improvement and things like that, i dont know if my issues are software related or if my phone is defective or not so im not sure what to do. i contacted google and there are going to be sending me a replacement but i fear that it will be the same issues again, other people online have posted that they have received a replacement with the same issues, so i just hope for a good working replacement is it just a bug that can be fixed in future updates, it is a new OS and a new phone so there will be issues from a launch device.
