I got a warranty replacement phone & i suspect it is used. It has a constant notification that says, "CHARGING CONNECTED DEVICE VIA USB". It never goes away unless I plug in the charger & restart the phone. As soon as i take the charger out, it's right back to the constant USB notification!! I am so mad because i get a defective phone in place of a defective phone! And to top it all off, i have a nasty broken leg, ankle, & fractured back so it's not like i can just just jump in the car & go get it fixed. Please help? I have cleared cache in android system app & restarted phone which did absolutely NOTHING. Suggestions?????
