when I turn on my samsung nexus it just keep on rebooting
I have my phone for 1 month and then my mom noticed that every time I charged it, the battery becomes hotter and hotter and it took so long to be fully charged and then 1 night. I let my phone playing a music overnight until it shuts down and then the next morning after I charged it, it keeps on rebooting until it turns off again. And I don't know what to do. Can some one help me with this one?
