Why won't my phone turn back on?

[AC Question]

I was taking a video on my phone and then all of sudden it wouldn't let me get out of the video and it just kept playing over and over. So i turned the phone off but it didn't turn off completely it is still blinking blue and green and i don't know what to do. Its been about an hour that its been doing this.

Hi and welcome to Android Central.

What type of phone are you using? Try holding the power and wolume button down for 30s, hopefully this will reboot the phone completly. You should probably also plug it into a charger.

Goodluck
