Only got phone yesterday as far as delivery and service are concerned emails etc all fine.However it's a Google Pixel3 phone with an EE sim on making my third phone call the person on the other end could hear static and many strange voices which were drowning out mine.This went on all evening despite me doing a factory reset it got worse.This morning I was going to send the phone back but wondered if it was something to do with my WiFi.The Smart TV wasn't on so I tried the phone no problem put TV on problem returned .Switched WiFi off on phone no problem switched it back on could hear what sounded like a man's voice from a TV station when I rang my landline .Switched all WiFi off phone including data allowance WiFi and phone has been working fine Don't think this is a hardware problem but something to do with the WIfi signal and EE sim card .Am waiting a couple of days to see if problem fully clears before contacting customer service.
