also repairing your phone or updating to a newer firmware might solve this, which build number do you currently have?

With the butto+volume up it seems working! Why it do like this?

there seems to be a bug with your phone, try to repair it with SUS and see if it happens again, and any electronic if it gets too hot it will start acting up
