Oh, most certainly agree that this is a hardware failure. But, as my wife likes to remind me - bad code can break hardware (her last project was control firmware for an 80 ft printing press). You can burn out ICs and sensors with crappy code.
That being said, I just reflashed my phone to stock this morning and did a cache wipe - problem persisted - as bad as ever. Did a data partition wipe, and it's been acting great for a couple of hours or so - including the previously dead column. (which makes no sense to me at all - I was certain that was long gone...)
I'm quite positive that this will start acting craptacular again soon... I'm curious as to how long it will take. If it's a couple of days, then it's enough to get me over the weekend and get a new phone ordered through the company channels. Here's to hoping that the S3 (looks like the only current verizon phone to contain CDMA,LTE, and GSM radios) will be unlocked for local sim cards soon (or one of the fine members here will find out how). That's why I loved my D2G - pop in a local prepaid sim right when you jump off the plane! None of this VoIP over LTE business VZW is claiming is "Global-Ready" on their other offerings...
