VZW's so-called "universal" car charger

As someone in the CS field, I still have reservations about these issues. I really don't see how varying voltage from a charger is going to in any way modify how the system is reacting. There are two possibilities with the voltage: higher or lower than recommended.
If it's higher, you should see excess battery wear, possible shorting of circuits, overheating, or at worst physical damage to the boards.
If it's lower, you really shouldn't see any problems other than the phone isn't recognizing it as a charger, or something to that effect.

I think there's a third option: variable/unsteady. If the voltage or power is changing rapidly, and there is plenty of spikes and dips, there could be unintended results, like we're seeing. The charging circuits might not be able to deal with a sufficiently noisy power source.

So your cigarette lighter is to blame?

No, but the circuitry in the charger that drops the charge from 12-14V down to 5V very well could be.

My girl has a Samsung Mythic that uses the same charger and one night I forgot my charger so I used hers. Possessed by demons is the perfect description. It was doing random things typing random stuff searching then stopping and everything in between. I don't understand how a charger can do this though.

I been thinking what if there was a short or leak in the transformer, wouldn't you get a lot of RF?

Varied and spikes of RF might induce currents in some of the circuitry of the phone.

I've always mixed and matched chargers, as long as the voltage and amperage were close. To echo others if it was over amperage the charging battery was warmer than normal but when using a lower amperage charger the device did a lot of nothing.
