Setting a timer for a long period of time, i.e. multiple minutes, is a performance and correctness issue on Android as it keeps the timer module awake, and timers can only be called when the app is in the foreground. See https://github.com/facebook/react-native/issues/12981 for more info.

I also had this bug, I was investigating, and then I came up with the solution that using expo will not solve, however, it can be hidden.

Write this code snippet in the scope of your component, after the imports:

LogBox.ignoreLogs(["Setting a timer"]);
const _console = _.clone(console);
console.warn = (message: string) => {
  if (message.indexOf("Setting a timer") <= -1) {
    _console.warn(message);
  }
};
