Around two years ago, we published an article saying that despite the claimed existence of a single, 15-minute app refund windows (now 2 hours), Google Play actually had multiple refund windows available to customers that were automated up to around 48 hours after the purchase of an app. Specifically, from a period of 15 minutes (again, now 2 hours) to up to 48 hours after an app or game was purchased, simply submitting a refund request would generally result in a refund being issued automatically, without regard to reason.

At the time, we actually confirmed some of this with Google's PR, though they declined to state that the 48-hour refund windows was fully automated, likely to discourage abuse of the system.
