My note 8 has had the problem of cutting in and out while on calls since I received it, but I thought it was a zone that I traveled thru. This has been getting increasingly worse for the several months I have owned it. Conversations are fragmented. I randomly cannot hear the far end, or they keep cutting in and out. They say they can hear me without interruption, but my ability to hear them is sketchy and random. MOST Frustrating
