iPhone 12 Pro Max dropping calls and poor phone signal
I have just received an iPhone 12 Pro Max and am having issues.
The signal is much poorer than my iPhone 11 Pro Max in exactly the same place - 1 bar instead of 2.
The call quality is poor and calls keep dropping.
I have read on here others are having the same issue.
Is this likely to be software or hardware? I have tried everything and Apple support have been unable to help me.
iPhone 12 Pro Max, iOS 14
