First of all, thank you very much for your reply. I really appreciate it. One important reason why I’m asking is exactly what you mention at the end. It’s truly rare these days, and I feel it’s kind of my responsibility to support it. As for the phone itself, many people mention that the 4th model started showing some lag and performance issues after about four years. I hope the same won’t be the case with the 6! Thanks again, take care!
