Well, you don't tell us which device, but I'll venture to say that if it doesn't have it by now it's never getting an official update. I'll also venture to say that if the device is that old chances are that if you find a way to get Lollipop on it your gaming experience will not be pleasant. Lollipop is now FIVE YEARS old, this means your device is probably at least 6 years old, it's time to consider a replacement for MANY reasons.
