I have acquired an A20e and I cannot get my PC (Windows 10) to recognise it when I connect it using a USB cable. It charges from the PC but there is no acknowledgement on the phone or PC that it is connected. The only notification I get on the phone is that it is cable charging.

I have already tried;

- restarting both devices

- using a different USB cable

- ensuring the default USB setting on the phone (in developer options) is set to "Transferring files"

Help please!
