@kugiigi Wow! T9! As somebody who still often "dials" a phone number, I always just figured those contact names that appeared as I started dialing were predictions based on the phone number.. but pretty bad predictions Finally I understand! That seems like a really useful feature! (also, I think T9 WAS the one where you only had to press each number a single time.) Kugigi, it seems you did not create the (perhaps handy) bug. I have it in Focal, it's just in a different place - in line with where dialed numbers appear, left hand side. Again, it's the same place Create New Contact button will appear once something is dialed.

@d4f0 @messayisto thanks for your replies, I'm beginning to think that there is nothing wrong neither in force-adb nor in systemd (!) and the problems comes from the device tree of the FP5, that is, the kernel configuration. Changing force-adb could be an easy work around but mostly wrong. I'll try to explore the FP5 kernel code to see if I can find the problem all by myself (enthusiasm level: ) Edit: created this gitlab issue to make the problem more visible.

@gpatel-fr Perfect, thank you!
