Hi. Eversince I updated my Galaxy A30s from android 9 to 10, I can no longer transfer files from my pc to phone. My pc can't read my device on the files folder but there's a notification on my pc that the device is connected. I tried using dff cable and it's the same. There's a certain button on the USB setting that I can't change. It's asking for "who would control the USB". The options are: 'connected device' or 'this phone'. It seems like the default button is 'this phone', however, everytime I try to change it to 'the connected device', it wouldn't switch. Before I made an update, I could transfer files well. I don't even remember if there was such option in the USB setting on the ver
Same problem as well, and I'm very frustrated about it. I can't switch it back to this device. And more than that, it seems the latest update that I downloaded affected my charging since my phone isn't charging anymore. I have to switch it off and try multiple chargers so it could work. Gladly, an oppo charger works while my phone was turned off. But it would take hours to be fully charged. Tsk, I shouldn't update my phone, but the notification above is bothering me. Is there any way how to uninstall the update?
