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
Some travel routers have a USB socket for media.
They’re usually used to make connecting to hotel Wi-Fi easier (you connect your devices to its ssid, then connect to its admin page and connect it to the wifi, or just plug it in to the lan).
Tp-link ac750, for example
