Does the cellphone processes in the background creates its own floor noise that goes into your recording app?I use a sony ecm717 with a attenuator cable and the field recorder app from Germany. I've never really noticed floor noise when I was using my D8 send the M10 for many years. But since using a samsung phone, i've noticed floor noise more often. Are there things that I should make sure my phone is not running in the background Some sort of setting I could turn off if it is creating noise internally? Thanks for any thoughts!Scott
