This app is garbage. It continually stops. I have tried everything posted to fix the problem, uninstalling and reinstalling, changing background settings, changing system power settings, and even factory reset my phone. Nothing Stops this stupid app from malfunctioning when the screen turns off. No, I don't want to hear from Google support asking me to contact them, I've already done that to no avail. And Google has no will to fix it, see for yourself. You get what you pay for
