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.
The iPhone 14 Pro and iPhone 14 Pro Max will debut on Friday, and the first reviews are already out and they're pretty positive. Both feature a new 48MP camera sensor, satellite SOS and crash detection, but the key difference you'll notice is the new "Dynamic Island" that includes many software touches.
