I’ve got a tablet with way more storage space than my phone. I’d like to be able to access all the files on it from my phone, just for viewing, without having to manually set up both devices for something cumbersome like TeamViewer. But also without having to use cloud storage. Is there any way to do this?
I use the app X-plore file manager to manipulate files on android. One of it’s features is hosting either a http web app, or a plain ftp server to share files to other devices on the local network.
Combine that with a vpn to keep the two devices in the same network and you’ll have self-hosted remote access. I host an OpenVPN server from home to keep my mobile devices within my LAN able to securely access my services and keep them behind pihole for adblocking.
