My phone has been turning on and off on its own since last night. What do I do?

[WPCentral Question]

Also, when I push the power button it either doesn't turn on or takes a while to do so, and it assumes I want to turn it off when I push the power button when I usually have to hold it down.

It is because of more use of your mobile phone, please switch it off for about 30Minutes then turn it back on. it will be alright!

Call an exorcist. Jokes aside, backup everything, give it a hard reset/factory reset. Always do this with 100 battery and plugged in.
