My pixel phone has meager storage. Could I use an old phone with bountiful SD space to serve up media via Bluetooth?
Any ideas if this would work practically speaking?
Edit: Looking for a functional equivalent of on-device storage space, i.e., for offline media consumption
USB phone jack is often used for power, so it’s unlikely available for OTG storage
Battery life in the server phone should be ok since it will be running in airplane mode with only Wi-Fi and/or Bluetooth, and display off mostly
Bluetooth is probably too slow for what you want, but you could use your old phone as a Wifi hotspot and even install various server software on it via Termux.
