I was unable to get connected to my home WiFi on this iPhone 13 where as on iPhone15 it was working fine. I contacted Apple India and got support from Phillip. He checked up my other phone with serial no and told me to show the screen with my camera. He resolved the issue as phone was not updated since June 24. He has been guiding us with great patience and understanding as we are not very tech savvy. Also helped us to back up issues. I am doing my update and phone is working fine. I am personally delighted to interact and resolve issues with Apple rep Phillip. Great help and big thank you
