Click Start, wait a few minutes (at least 1 min), click Stop. Now the elapsed time/duration should be displayed. Put the app in the background or lock the screen, wait 1-2 min, open the app again. Again, the total duration should be displayed.
Close the app, wait 1-2 min, open the app again. The total duration since you clicked Start should then be displayed again.
If Start is clicked again, the procedure starts again.
But, I think whenever user changes system time, timer also changes. I believe you are using system time on button click instead of taking online timeā¦
But after stop, I need to kill the app. Because once I started the timer and stopped then come back from the ideal mode mean , it shows me irrelevant timers. Donāt know the reason.
