As a heads up, we had purchased two iPhone 12s in December. Recently we tried to attach an Apple Magsafe wallet to the phone. The wallet would not attach to either phone. Apple expressed shipped two replacement Iphone 12s, and the wallet attaches to both phones. Since same behavior occurred with two phones, there may a MagSafe quality issue on some batch of iPhone 12s. Sincerely doubt Apple will proactively notify customers of this issue. But we found it strange that it occurred with two phones.
