Is UT in PinePhone same thing than in another phone?

The best ongoing information can be found here: https://gitlab.com/ubports/community-ports/pinephone

As mentioned in the README, the Pinephone doesn't rely on the Android kernel/halium like every other UT device does. That's probably the most profound reason why the Pinephone is 'so special' compared to other devices running UT.

Would it be possible to install a pure linux kernel and a linux OS (UT, etc) on an android device? I mean, if Android kernel comes from Linux, probably it means the hardware is not that different. So, why not develop a linux kernel for Android phones? Why the need for the android kernel? only because is already there?

We cannot develop Linux for Android devices, because they rely on proprietary drivers depending on old Linux kernel versions. The manufacturers refuse to update their firmware and devices stuck with old kernels.
