My phone is lagging. I cannot press the button to turn it on. It has hardly no response when I press a key. Unable to get to anything on my phone.
We need more info to help you. I will reply when you post additional information.

I would try a battery pull. Simply remove your battery and reinsert it. Then power on the phone as usual.
