I've been using the Synology Drive app to sync folders between several PC's and Android phones.

I recently got a new Nokia G42 5G (Android 14), which needs the same folders syncing.

However, on the Nokia the Synology Drive app would be flaky with syncing, having to manually open the app and run the sync tasks, which should run automatically.

I got fed up with this and moved to Syncthing instead, only to find it has the same problem.

Syncthing has an option to 'start service automatically on boot', which the Nokia is simply ignores.

Opening the Syncthing app manually immediately causes the sync tasks to run.

This does not occur on my Samsung A22 5G. Both of these apps runs happily in the background and I never have to touch anything.

I can't see any power settings on the Nokia that might be preventing the app from running.

I've come to the conclusion that 'auto start' is broken on the Nokia, it would explain why both Synology Drive and Syncthing don't work without manual intervention.

I've also tried a third party app 'Boot Apps' to run Syncthing on startup, which hasn't worked.

Any ideas as to why the Nokia is unable to start apps at startup?
