I have dropped my android phone and the screen broke. In the meantime the battery has died. I would like to use adb to make a backup (I run Ubuntu).
adb devices
shows the device. However it is shown as unauthorized. Can I somehow use adb to backup the phone nonetheless?
PS1: This is a Oneplus 7T on Android 12. PS2: I have managed to connect the phone to an external display via a USB type-c hub (It shows a screensaver-like screen with the time) as suggested in a Oneplus forum. However, the keyboard and mouse signals are ignored by the phone).
