My Iphone 13 Pro went to abnormal after 18.5 update

Hello ,

I updated my iPhone 13 Pro (256 Gb) to 18.5 and I am facing multiple issues like cellular service disappearing, wifi getting disconnected and getting restarted some times.

my phone was working very good before the update . I connected with the online technical team and they asked me to connect with the Authorized center.

After travelling over 300 kilometers specifically to resolve an issue that arose immediately after

updating my iPhone to iOS version 18.5, I expected a thorough and responsible

diagnosis instead , the staff did not even physically check my device. They merely reviewed the system update logs advised me to replace a part without performing any meaningful inspection or testing of the phone itself. They did not even touch my phone.

This experience is extremely disheartening. I expected at least a basic level of attention and professional service. If such recommendations can be made without physically checking the device, it raises serious concerns about the reliability and fairness of your support process. I kindly request a formal review of this incident because the phone was working very good before the update. I am sure the bug has come with the update. Please help.
