I've been using aftermarket chargers for quite some time without problem and recently in the past week my phone has been going on the fritz! At times the right side of the screen is unresponsive, other times it makes random touchscreen presses all over the place. Both of these scenarios take place while the phone is plugged and unplugged. On times when i fully drain the battery and plug it into the car charger the phone works okay though but it still has those issues though not as frequent. The current charger I'm using is a 5V 500mA aftermarket so I'm wondering whether you guys think its guts are fried or should I go pick up an OEM one from VZW?
