I got my SG Tab last year for Christmas, and last night, I was charging it, and I unplugged it. It went from 100% to 17% when I just unlocked my tablet. Then it suddenly died on me. I panicked because I thought I destroyed it. When I plugged it back to my charger, the screen was black, and there was a yellow battery charging, then it froze and discontinued to charge. I did it again and same thing happened. I did this like many times (around 20 times). I didn't know what to do. I told my mom and she said I have to let it charge without using it. So then I watched TV then went to sleep. This morning, I tried to turn it on, but it didn't charge or turn on. Please help!
