I think he meant "bad reception" meaning weak signal strength Xperia 1 suffers from. Maybe those close to the transmitter are not impacted. This may be caused by some carriers as well.
Anyhow, while having same carrier I am experiencing much worse signal strength on Xperia 1 that I had on XZ Premium. Now I am trying to switch the carrier (left current one) to see if this will help.
