My Son plugged In his LG G4 to Charge it Up.. Cord & Plug were separate pieces he pulled from a Drawer.. While Charging phone Pinged indicating a Text had been Received.. Attempting to Answer Text while it was still being Charged , Home Button wouldn't Respond and the Background went back to Original .. Phone is Basically Acting Out of Sorts.. (1) Could the Problem have Originated from the Charging Cord (2) What can be done to Restore the Phone back to Fully Functional ?? Cheers Thanks.
