Phone stays awake while charging.

Hi. I have bought a meizu mx4 pro from China and reiceived it two days ago. When i connect it on charger the charging screen comes on and stays on for 10 seconds, after it closes(sleeping0 for 2 seconds and comes on again. I tried to put it in sleeping mode(by pressing power button once) but it still comes on. I tried factory reset but still nothing. How can i solve this.
Thank you.

what do you mean by charging screen?

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
