Dear Apple Support Team, I hope this message finds you well. I am writing to express my frustration and seek assistance regarding an issue I am experiencing with my new iPhone 15 after updating to iOS 18.0. Since the update, my device has become unresponsive and is stuck on the lock screen. I have attempted multiple troubleshooting steps, including resetting and restoring my iPhone, but unfortunately, none of these actions have resolved the problem. Here are the specific steps I have taken: I performed a force restart of the device by following the appropriate button sequence. I attempted to restore the device using iTunes/Finder by putting it into recovery mode, but the issue persists. I have ensured that my device is charged and that I am using the original charging cable. Despite my efforts, my iPhone remains unresponsive, and I am unable to access any of its features. This situation is quite concerning, especially considering that I rely on my device for daily communication and tasks. I would greatly appreciate any guidance or solutions you could provide to help resolve this issue. If there are any further steps I should take or if I need to bring my device in for service, please let me know. Thank you for your attention to this matter. I look forward to your prompt response.
