Android OEMs still don't provide the six years of updates you get with Apple phones, but some manufacturers are trying to close that gap. OnePlus is adding an extra year to its smartphone update promise and is now offering four years of major OS updates and five years of security updates.
Timeline-wise, this plan matches Samsung's, though Samsung offers monthly security updates and OnePlus doesn't. The company is still only promising security updates every other month, so it can't do too much bragging. Android-maker Google—who you'd think would have the best update plan—is in a distant third, with only three years of OS updates and five years of security updates.
