Recently, due to a voltage overload at home, my original charger got damaged. Got a spare one yesterday (iPhone charger it seems; but not original). When I plug in the charger, the touch screen becomes unresponsive and sometimes it asks me whether I want to connect the phone in mass-storage mode or sdk mode or sync and connect When I unplug the charger, the screen responds as normal I couldn't find a thread and/or discussion related to this issue other than this Somewhat weird but I am not sure what it is and whether it would damage my device or not
