I'm testing a kiosk app that runs continuously. I have setup auto-updates in the Play Store and am trying to see when it updates. I left two tablets running for over 3 days, and only after they died and I restarted them did the updates occur. The app was not running on boot.
I tried to restart the devices during the 3 days to no avail and even the apps that weren't running didn't auto update so I know it's not because the app is running (my first assumption when doing research).
Looking online, I'm seeing a lot of people say that auto updates happen at random and only on wifi etc. I've had the tablet on wifi the entire time and let it charge over the first day to see if the power state changed anything.
Is there a way to test auto updating reliably? When does the Play Store do updates?
