Anyone having charging issues? It seems if I barely touch my charger while it's plugged into my phone it will stop charging, and begin charging again if I barely touch it again. Say for example my phone is charging and I get a text message and pick up my phone to reply, it'll go from charging to non charging and so on about twice. Sometimes I wake up in the morning with the charger plugged in and my phone is nearly dead because it didnt charge. Anyone else having the same problem?
