So after being fully charged overnight my phone randomly turned off. I tried turning it back on but it would only vibrate, have the samsung logo appear, and then turn off again. I tried everything I could to fix it; I tried to hold down the power button, then I tried taking the battery out, then I tried to hold down the home, power, and volume up buttons all at once. After those didn't work I tried to take out my battery for a little, have my phone charge, and then put the battery back in, but nothing worked. Can anyone help me??
