It’s not common for Android devices to get more than two major OS updates. So when a device is released, it will only be supported for two major OS updates in most cases. There have been deviations from the norm in a few cases but the two year cutoff is more or less the norm in the industry. You can imagine how happy OnePlus would have made its customers when it announced that it would update the OnePlus 3 and 3T with Android 9 Pie. The company has followed through on that promise today.
The OnePlus 3 and 3T are now receiving their Android 9 Pie update today. This is the third major Android OS update for the device. The OnePlus 3 series was released by the company in 2016. It’s now rolling out Android 9 Pie for both devices.
