Install notice:
Nowadays devices are coming with more security in context of Battery power consumption. By default devices keep almost all apps in power saving mode. It means in some devices your background work won't work as soon as you come out from the app. The way to achieve that behavior in these two manufacturers is:
Xiaomi:
Go to the Battery => Power => App battery Saver => select your app and choose No restrictions (for Background settings), then Allow clock run at Background.

Samsung:
Samsung Smart Manager App used to stop all background work after 3 days if you don't come to your app. So the way to disable this feature is:

Go to Battery in the Settings => Unmonitored apps => Add your app to the whitelist.

For other devices there should be same power options either in settings option directly or some app are given to handle it.

Otherwise, the desktop clock will stop after a period of time.
