I also have found a similar issue, going on a new page and coming back it seems that it takes a few thousandths of a second.

I did a test with an Android device and an iOS device. In the iOS one I have always held in the countdown page instead in the android I went back and forth in the countdown and after push pages and back to countdown 5-6 times the countdown on Android had a difference of -3 seconds compared to the one on iOS.
