Doogee dg310 charging only when the phone is turned off

Hi,

My Doogee dg310 stop charging when the phone is turned on and the only way to charge is when I turn it off.
also I can't connect it to the notebook because I don't get the message that a USB was connected to the phone
I rest the phone twice but it didn't help

Thanks
Kobi
