Google finally takes action and starts to take control of Android upgrade. An increasing number of smartphones are adopting the Android system, but system upgrades are not that simple. Therefore, it is time for Google to control the Android upgrade... Android is gradually growing up and continues to attract heated attention online. However, unfortunately, many Android users are complaining at present. The crux of the problem lies in the fact that many Android mobile terminals cannot be upgraded smoothly. I have personally experienced the troubles of upgrading an Android phone. In the end, Google's brand will be affected after all it is the original owner of Android. For Google, it is time to intervene and take control of the Android upgrade, no matter how angry its partners are.
