iPhone 16 pro max signal

Have apple acknowledged the poor signal strength on these phones yet .

is there a fix or replacement phone needed .

iPhone 14 Pro Max had no issues 100 mb download speed ,16 pro max sometimes I can not get on internet phone always goes to answer phone if called .in the same location as the 14 .

keep seeing sos or 2 bars 5g which means no or little internet.

reset carrier settings etc still same network is fine so they say .
