However, Google changed that in newer versions of the OS for the sake of security.
However, users can change that to get their preferred USB mode as default on their Android unit.
The method is fairly easy but involves a few critical steps.
To change the USB configs onAndroid, the machine first needs to have a hidden setting enabled.
It’s called ‘Developer Mode’ and can only be enabled manually.
If the Build Number option is not visible, expand the ‘Advanced parameters’ menu to find it.
Once that happens, users will see a message that says, ‘You are now a developer.’
To transfer files, select ‘File Transfer.’
To tether the phone’s mobile connection with a computer, select ‘USB Tethering.’
Once done, eject the phone and unplug the cable.
The same method can be used totransfer files to a Chromebook.
Files can now be dragged and dropped between the Mac and Android phone.
If the software is up-to-date,try restarting the phoneand connecting again.
Very often, the culprit is the USB cable.
Try connecting with a different USB cable, preferably one that came in the box of the Android phone.
Alternatively, try connecting to a different USB port on the same PC.
