@Inali In the Q&As you can see an FP5 almost every time. They probably just want to make sure they have something that works well on the release I can imagine. It seems to be running from what is visible and publicy shown. With a good working release (ideally with Waydroid) the FP5 with UB Touch would easily be a great daily driver and literally the best phone in the line up with official support!

Let them Cook. It probably will be great!
