This is the Samsung Oreo upgrade roadmap
On your high-end devices, Samsung updates relatively well. For two to three years, a device from the Galaxy S family or the Galaxy Note family will always be up to date, with the latest version of Android available. They will take more or less time to arrive but, on a regular basis, they will arrive. This is not the case with the rest of the ranges. Samsung has many mobiles and it is difficult to keep them up to date. The mid-range and the low-end range is very wide, and it shows.
The support is, basic, less. These devices are not built to last that long and it shows in the software. Even so, it is normal to receive at least one version jump. In the case that concerns us today, we are talking about updating to Android Oreo from previous versions. When will Samsung’s mid-range and low-end terminals be updated? This is the filtered calendar with the roadmap:
Android fragmentation is still a problem
At the end of the day, what this calendar makes clear is that the fragmentation of Android it is still a serious problem. The calendar indicates that the updates will take place at the end of 2018 and the beginning of the next, when Android Oreo is more than a year old and Android 9 Pie have been available for several months. Despite being quite a few devices, continued expansion makes fragmentation a bigger problem in the end.
Wonder if Project treble it will eventually solve this problem or not. On the one hand, it will facilitate the updates of the operating system, but it will not be mandatory in Oreo until the devices are released with this version of series. In addition, in the end it is also a question of whether each company wants to invest resources in it, something that does not always seem to happen. However, if you have any of the mobiles from the list above, you will receive Android Oreo.
