who is downvoting me and why?

You’re probably making them feel stupid, people downvote for no good reason. It’s a them problem, not a you one; everybody should check AlternativeTo before asking for recommendations.

Yeah, phone to laptop, and I recently synced all backups and files from an old phone to a new one, too. Once you have the computer setup, you can basically connect phones by reading its QR code.

If the official Syncthing Android app is giving you a hard time, maybe try Syncthing-fork? IIRC that’s only the daemon and web GUI wrapped as an app. But I’ve used the main app only for the past few years.

I’d really recommend giving Syncthing a second chance, twist a few knobs in the settings until it works. I’ve used it for years with barely a hitch.
