hi
I need more info to get a better picture:
[] was the battery drained? (not charged for a while, left with apps open while low on battery etc)
[] When you charge it, does the LCD light up and show the battery charging? if not, wait for a few mins. (if it doesnt, confirm that the charger works with other devices to rule out charger issue)
[] was the device dropped, watered or something?
[] could you check if the battery is bloated?
Let me know what you find.
Thanks
