I recently tried this with my old Huawei phone which had a broken screen but also a bunch of photos I would've wanted to save locally. It wouldn't even show up on `adb devices` let alone the programs that relied on adb IIUC. I even tried tapping the sequence for my code on the broken screen, as well as trying to turn on voice control to manually unlock the phone, but that didn't work either. I would be happy to give it another try though.
