Phone won't turn on?

[android255]

I had the phone for.. about a week now..
I was cleaning the house and I put it on the top of my bra strap to listen to music at the same time.
After the song finished I was done with cleaning so I took it out to call someone but now it won't turn on.
It was completely fine.
I have pressed on the power button loads of times but it just vibrates.
What do I do and what's wrong with it?

Thanks

My android ZTE is on but when I touch the screen to open it, it does nothing. I can restart it and shut it down but nothing. I had an incoming call that I didn't answer it and after that is when all this happened. my number buttons are even faintly showing.
