VZW's so-called "universal" car charger

[SuGaR]

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.
