I bought an adaptor ("luxorparts") to connect a memory stick to my Xperia XA1 and it worked fine. I didn't need to install a driver. But suddenly something happened, and then the phone will not recognize the adaptor / memory stick any more. It still works fine to connect the adaptor to a laptop.
I've tried to turn the phone off / on, and taking the SIM-card out / in but nothing works.
It possibly is a configuration problem. Any suggestions ?
