v4.4 is the kernel version of the kernel included in the original software. Multiple users of older smartphones switch to alternative distributions once their device is no longer supported by the manufacturer. These alternatives often include a more recent kernel. See e.g. https://en.wikipedia.org/wiki/List_of_custom_Android_distributions.
