I'm trying to move data from a Pixel3 to a Pixel1.
Bluetooth
I am able to pair the devices, but for some reason they are disconnected as soon as I switch to another app (to a Files app to copy data). I'm not seeing any errors.
USB
I am able to connect the devices via USB, but only one way! So I can move data from Pixel1 to Pixel3, but I'm not able to move data from Pixel3 to Pixel1. In settings there is a "USB controlled by..." switch, but when I press it, it tries to switch for 10 seconds and then times out. Again, no error message to tell me what went wrong.
Surely there must be a way to move data between 2 Android phones? I don't want to use a computer/cloud as an intermediary step.
