I don't need to search anything, I've read them all. If and when an Andromeda device ever comes, it will NOT be a phone. It will be a pocket PC which you may be able to make calls with. There is no clarity whatsoever on what chipset it will be based on, whether there will be legacy support at all, whether it will be able to run Win32 apps natively, through an emulator or at all. PWAs are still lacking badly. There is no clarity even on the size of it and I definitely do not consider two 7" screens as "pocketable", never mind a "smartphone form factor".
Given that an online petition supporting the release of an Andromeda device (although nobody seems to know what it actually is - a bit like Brexit) seems to be struggling to reach even 15K signatures after a week, I seriously doubt there is a business case for it (or, as you say, "a lot of folks are very interested") - and ultimately that will be the critical decider, no matter how sexy and cool the concept is in artist's renders and how loud the small number of fanatical winphans are.
There was already a dual screen Android device released last year (the ZTE Axon M) and it got nowhere, even with the benefit of full OS and app support (Android apps automatically scale to the screen size used, so no need to faff around with UWPs and PWAs)
- I guess you hadn't even heard of it until now. What makes you think that an offering from Microsoft would fare any better with developers and consumers after being burned several times in the last 7 years ?
You are in for a very very long wait if you want a Surface Phone. It's been rumoured since 2015 and look where we are now.
Oh, the Surface line - still making losses on every single product, so I seriously doubt Microsoft are pleased at all about it.
