Is UT in PinePhone same thing than in another phone?

[Veraendert]

On the Pinephone, UT does not use Halium, the middleware that´s usually found in Android devices running UT (and LuneOS, Plasma): https://halium.org/. Furthermore, the Pinephone aims to run the mainline Linux Kernel, something Android devices normally don´t do. With some exceptions, when you have an Android phone, you´re stuck with the Kernel version that the devices came with (including binary blobs). That Kernel may or may not be updated but you´ll never be able to switch to a newer Kernel.

So while the UT touch layer, the userland, is the same on pinephone and converted Android phones, beneath that layer they´re very different.
