Thanks for getting back to me . I know that a Factory Data Reset is an option, but I'd rather not have to do that if I don't have to. Am I being more scared of a FDR than is necessary?
IMHO everyone should know exactly what they need to do if they have to do a FDR. This will happen if your phone breaks, or is lost, or you buy an updated model - by definition, you will be starting from scratch.
The only other thing to try that I can think of is to uninstall apps (one or two at a time), restart the phone, and see if you get the phone working after an app uninstall. Maybe that will point to a third party app that for some reason accesses the headphone jack when something is plugged in and is causing trouble when it sees something get plugged in. (You don't have an app that specifically uses the headphone jack for an external device, like the Square Card reader and app? If so, I might start with an app like that.) If you don't have an app like that, though, I suspect that it may be corruption in a system app, which would probably be nearly impossible to discover.
Yes, FDR is a pain. You have to set up home screens (unless you use a third party launcher that lets you backup and restore your settings, like Nova Launcher or Action Launcher). You have to reset settings for notifications, etc., if you've changed any of those from the defaults. If you don't restore from a backup to Google, you have to re-enter WiFi pass codes. You have to re-establish any Bluetooth connections. Still, like I said, you won't have this phone forever, so at some point you'll be rebuilding a new phone from scratch or from backup. However, it seems to me that fastest and most sure way to fix that error.
You may want to see if other people answer this, though. Perhaps somebody has an exact idea on how to fix that issue besides the one that you tried (uninstall the Google Search app update.)
Good luck, I hope that you get it working right.
[edit] I actually thought of one last thing that you can try - the Verizon Software Repair Assistant.

It's possible that the Repair Assistant will fix a problem caused by something that went wrong with the update, It may be worth a try, anyway. I've never used this myself, but I am pretty sure that it allows a reinstall without losing any of your data. One thing I remember about the Repair Assistant is that it may not detect your phone if you plug into a USB 3 port on your computer. If you find that this happens, try plugging the phone into a different port on your computer.
