http://androidforums.com – I charged it overnight and when it was morning I took it off the charger because it was up to 80%. Then I used it and soon it couldn't come on! I try holding the power button and resetting and computer but it can't come on! If my mom knows it can't come on, she'll be mad at me! please help! She won't do warranty/repairs so pretty please, just tell me the most easiest way to get it on I appreciate it TT^TT (General)
