Mom's phone is working but the USB-C port is not anymore. It won't charge, and it won't connect to my PC. It's got about 20% charge left so I'm trying to figure out a way to save her data before the battery drains completely. The phone does not have a removable SD card. How can I transfer data out of Android using Bluetooth or Wi-Fi? Is there a free app from f-droid that I can use for this? I'm thinking of something like an SSH server (or HTTP, FTP).
