PSA: Apple has averaged about one zero-day vulnerability per month since January. The latest came with iOS 16, which hackers may have actively exploited over the last month. Apple issued iOS and iPadOS versions 16.1 and 16 earlier this week. Users with compatible devices should update them immediately.
In a nutshell: Bugs in new phones are something that's become a common problem for consumers. The iPhone 14 Pro seems to suffer from quite a few of them, the latest of which include random restarts and cellular connectivity issues.
