Hi Matt
I have the same issue I'm on EE. Does it cut out randomly during a call even if you have signal other person cannot hear you, then at some stage suddenly they can hear again?
Unfortunately I had this problem with xz premium having around 4 replacements, and all had same issue to differing amounts. Here's the post but unfortunately Sony have not replied as yet /t5/Xperia-XZ-Premium/XZP-anyone-else-have-mic-cut-out-clicking-issues-XZ-premium/td-p/1237422/page/...
I received my xz2 on pre order, same issue and am on my replacement also with the same issue just over a week old! Very frustrating isn't it.
I recommend going for a replacement with your provider as I will be again, but not sure how many I will do before giving up on this handset also.
Such a shame because the rest of the xz2 is great! It's a joke that a £700 phone can't even make calls properly in 2018 when a cheap £15 phone doesn't cut out during calls.
Sony if your reading this please address this serious issue! This bug has plagued the xz premium, and seems to be same with xz2, currently on my second handset which I will be returning shortly.
