Galaxy a20e, until today it went perfectly to transfer files from the PC to the mobile. Today I connected the mobile to the PC, the mobile does not appear on the network, it beeps constantly, and the usb connection screen from the mobile always flickers. The cable goes to charge both the PC and the mobile charger. what's wrong with it? I played with developer mode, I forgot when, could it be from something like this? I clicked 7 times on the mobile settings and in the developer mode menu I also clicked on debugging mode. It doesn't work that way either. What's the matter?
