Samsung Magician

I'm using this app for the T7 on the S23 Ultra. Technically this app works for me. Password feature does seem to work. However, after installing I'm getting notifications that the drive needs formated to work on my phone. Already did that nearly a year ago. Also getting warnings about unsafe disconnect even though I always use safe method. Have also updated firmware via PC. The app has bugs but does work for security. Just use a file explorer to access drive.

It works as advertised but is minimally useful after initial setup (set up PW, fingerprint, etc.). I would like to see more functional features such as a file backup feature, or folder sync type function that lets your users auto sync folders between the phone and the drive. After all, isn't that the whole point of why people buy your product? My T7 Touch 1TB was not a cheap device and I'm disappointed that I have to go looking for third party Apps just to have basic sync/backup functionality to make the most of the device.

Seems to work OK for me, but a little wonky. I think the app is only designed to change the name and security status. You use your file manager to access the files. I've never used the file manager that came with my phone, but I have a separate one, and everything seems to work fine. The thing wonky is it always says the drive was unsafely removed, even though I did safely dismount it.
