One of the major complaints with Android has always been the update saturation. For starters, by the time manufacturers start pushing a major stable Android update to their devices, a new Android version will already be out. Hence, most people are stuck using older Android versions.
This was a significant issue during the Android Nougat days, where a survey showed that around 40% of people were still stuck in Android 4.0 or even below due to the lack of updates. That’s when Google announced the project treble to make it easier for manufacturers to push updates. Well, that might well be the reason why the updates situation has gotten much better. According to recent statistics, most devices run Android 10, followed by Android 11 and Android Pie.
