Hey everyone, So I recently got Galaxy S4 (today). And I left it to charge as usual with the new phone. When I switched it on, and after some time the battery icon on the phone started to flash, and the led light started to flash red. When I put the phone is charge the icon does not flash anymore, and it says it's charging, but when I take the charger out, it's back to flashing. The battery is about 79% and it says 1 minute left for a while now.
