hope they will have success!

Volla already have to make some change on halium/libhybris to support the newer Android base (9) on the GS290, so their work could help other porting in others new devices.
Also in Europe is starting a discussion about the protection of EU users privacy against foreign countries (both in hardware and software side),so, imho, this is a good time to show the user interest in this with the adoption of an opensource os on an UE manufactured device... I think this could start or help a process of mind-change in the manufacturer sector and app developers about UT support.

@banderson5586 about the OpenStore status on arm64:
see HERE
and HERE

@banderson5586 maybe they don't want to resell it but surely for someone having a smartphone or tablet for free is enough....

...and this brings to mind my fourth Question:

was it not better to give these devices as a prize in a competition for the creation of the best apps?

(and I say this aware that in this way my candidacy would automatically, for the moment, be excluded since I am not yet able to develop for UT)

@UBportsNews I have already contributed here and there but have done only little things. I'm studyng how to develop on UT but I'm only an hobbyist so I'm not a so good investment...
But, I found that there are at least two other italian UT users near me (less than 30km, and they are very active in the Italian UBports telegram group) and I'm already thinking of share with them my rpi4 to help each other in the develop and test process. Also in Mezzago (a town 7km from my home) there is a little but lively linux community that could be interested in the UT and its app development.
Last but not the least I directly know and I'm friend with many guys from informatics engineering (from the university Politecnico di Milano) with which I collaborate in the Openstreetmap project and wikimedia foundation and that could be interested in software development on more exotic platform like UT

Q1 about Volla Phone: in the Volla kickstarter main page is said we don't have to give up the Volla user experience in an alternative free operation system...does this include UT? if the answer is yes will this UX option in UT be possible only on Volla Phone or will this option be also possible "upstream" in other devices supported by UT?

Q2 about Volla Phone: actually I can choose between Volla OS and Nemo OS as pre-installed OS. will UT be added as a third option?

Q3 about Volla Phone: how can we go from one OS to another? it will be possible to use UBports installer to install all OS supported by the volla phone?

@Pulsar33 to me it seems more like throwing a stone in the pond and then shouting "there is movement !!"
but that was a right move...maybe someone from there can help us port UT on RPI.
here the situation has stopped (not to say worsened since we lost the GUI operation ...and we don't know why )

litte OT: I appreciate more that the new hardware (that is always welcome) their UX. it remind me a little the dash with integrates lenses (or scope? I don't remember) plus a little the HUD in unity7...when I saw their presentation video I was wondering if is it possible to have something similar in UT...

Warning!: the last rootfs-rpi build (#51) has not the GUI.
Here the cat /.cache/upstart/unity8.log pastebin

@mariogrip I know that. I only used the terms/definitions in the first post. I am confident that all those changes will be backported (or forwardported)to the unity8 from edge
