We are at a not very good time in terms of the pace of updates for Android devices, but it is expected that with the latest releases this will improve considerably or the new version will arrive with too low a rate of devices updated to the latest version available. Obviously when we say latest version we are talking about version 7.0, we no longer mean 7.1 ... In any case, in January 2016 the adoption rate of the previous Android Marshmallow operating system was barely 0,7% on all devices, this rose in March to 2,3% So it is not that this year things are being done much better and it is normal for users to complain about it.
For now what we can see in this lower graph is that taking into account the time of year in which we are, the adoption rate should be much higher, but in this case it is not something that we are not used to, so directly if the results are somewhat higher than last year with the previous version, well better, but it is clear that we must continue working on it.
On the other hand, what we realize is that the terminals that are updated are usually always the same apart from the new ones from Google, Pixel or Nexus -high ranges, the Moto G, some Sony, Huawei and little else) and when already it's been quite a long time since the new OS was released, in this case about the year. In addition to this, what is not good for Android is that new devices are launched with too old versions of the system, something that happens less and less, but that continues to happen and this does not favor users. Hopefully, higher rates of adoption of the operating system will be achieved shortly. Android Nougat and is that it does not reach 3% of active devices it is not good and less good that 10,6% have Jelly Bean installed or 20,8% are in Kit Kat.
With the launches of the new LG G6, Huawei P10, Nokia and other models presented at the MWC, this figure will surely increase since they all add the new Android Nougat, but it would be better if the updates were available on a greater number of devices that do not. be the newly released.
