Hi, I couldn’t find an active thread for this, but I just wanted to notify that, trying to upgrade via F-Droid results in a Google Play Protect notification about the app being detected as a (possibly) “Harmful app”. Are there any recent changes that might have triggered a (hopefully) false positive? Or could this be related to Google’s impending lock-down of Android that will block apps by developers that have not provided ID? (see Keep Android Open).
**Edit:** noticed there’s a thread in GitHub with the issue already reported, [v2.1.1.0 flagged by Google Play Protect as harmful · Issue #287 · researchxxl/syncthing-android · GitHub](https://github.com/researchxxl/syncthing-android/issues/287)

Play Protect flagged it after I installed the update, but then I did a manual scan and the warning went away. I’m assuming it was a false positive from Google’s Play Protect.

The problem seems to have been fixed. I’ve just updated mine without a problem.

I stopped the installation process after this screen.
Does that not bother anyone?
Besides that it has been apparently abandoned/discontinued.

If you want an app to sync files on your phone, it needs to have access to the files. Without the permission, it cannot do its job. The warning is there to clearly inform the user that they are trusting a third-party app with their data. That’s a personal decision, but a technical necessity for it to work. At least it’s open source, so you or anyone else can verify what it does and does not do with your files.

Cannot confirm that. The latest changes in the repository are from last week.

The Google Play store version is stuck at 2.0.11 with no updates since December 2025 🙁.

The Google Play version has been abandoned. You need to use the version available from F-Droid.
