How can I troubleshoot Meizu M2 note?

I am a newbie here.
I also purchased Meizu M2 note recently and yesterday night, I noticed that in my dial pad the clear button and add button is not responding.
Is there any way I can solve it?
I tried every method, including factory reset.
Can anyone help me?
