Nokia 5230 SMS display name does not match the address book, the display name is wrong, but the number is correct. Master Gao, please answer.

I suggest you consult 10086, because 159 and 137 are both mobile, and there may be an error in the mobile network. As for the internal display program of the mobile phone, this kind of low-level error will not appear. If the display of the mobile phone is wrong, even if it is restored, it is wrong. It's useless We have to find the seller to exchange it. If you are a master of single chip microcomputer, you can do it again.
