Beverly says that after the last iOS 13.4.1 update on her iPhone, she has to reboot her phone to run any app. Leo suspects that the update was corrupted when downloaded. He recommends backing up your phone and then wipe it and reset your phone. Connect the phone to your PC via USB and then use iTunes to run the encrypted backup and wipe it. Erase all the content and everything. See if that solves the problem. If it does, then you can restore that backup.

Bob clicked on a link in an email, and now he's having issues with his phone freezing up. He pulled the battery and replaced it, and now it works OK. Was it malware? Leo says probably not. These days malware doesn't want to get noticed. It works quietly in the background.
Steve updated his iPhone to iOS 9.3.5. Leo says it's important because it fixes the exploit that enables countries to spy on iPhone users. But now Siri isn't working for Steve. He gets an error that he can't understand: "Please Try Again." Leo says a dirty microphone can easily do that. If it's also an issue via Bluetooth, then it points to something else. It could be a bad update. He can still dictate messages, though. Leo says that's a Messages issue then. The only thing he can do is backup his phone and do a factory reset.
