Now, no Galaxy device eligible for four generations of Android updates has been around long enough to run into that limit this year. However, that isn't the case for devices that are promised only three years of Android OS updates. For some of them, Android 14 will be the third and final big release, after which they will be downgraded to only receiving security updates and one or two minor One UI updates.
Here's a list of devices for which Android 14 is the third and final update:
Galaxy A52 5G
Galaxy Tab S7 FE
Keep in mind that the list above is of devices that launched running Android 11 out of the box and were eligible for three major Android updates, which will make version 14 their last and final stop. The list doesn't include devices that won't go past Android 14 because they launched running Android 12 and don't qualify for either the three-year policy or the four-year policy.
