Sending a text message from Sony Ericsson T707 will change the recipient's name.

The landlord doesn't need to worry about hardware bugs. Occasionally, 1000 times only appears once, just like computers always run wrong, not to mention hardware and software. Just go to Sony Ericsson official website to upgrade the latest software and keep the best new capabilities. Don't worry about other problems. You are much ado about nothing about this kind of thing. When I typed A before, I obviously pressed A, but I dialed B. And it was played many times, which embarrassed me. It's just that A and B have the same surname, so don't worry. This kind of problem is perfectly normal. Without software, it will not be perfect. Apple came out in four generations, so you don't have to take it too seriously. There is nothing wrong with the machine, just an occasional small program problem, just like making a small mistake. Thank you, landlord
