That’s mostly a function of controlling your own CPU architecture, as android IHVs are heavily dependent on updates from Qualcomm and others. Also, while they have supported old devices, they do from time to time unceremoniously make old apps incompatible which then stop working. Microsoft still has them beat in terms of backwards app compatibility in Os upgrades and MS did it over a diverse ecosystem of hardware which is far more costly.
