If they release in the next 20 hours, it'll still be less than 3 weeks…
Planet are a very small company, and I'm inclined to cut them a little slack. The Gemini itself was a few months later than we hoped, but it did arrive, and with pretty much the hoped-for spec (slightly better in some ways, not quite as good in others). From the vantage point of a year later, that delay isn't important; the device itself is. I gather that people who've had to contact them directly about e.g. broken machines have mostly been happy with the ultimate results. They promised a way to flash various operating systems, and they did so. (It may not be as easy to use as we'd like, but it's probably a darn sight better support than for most Android phones.) And so on.
As far as I can tell, Planet have been working in good faith all along, and so I'm happy to forgive them a little optimism on timescales.
By the way: does anyone know what the effects of upgrading from Android 7.1.1 to 8.1 might be? Will any of my apps stop working? Will I have to set up all my settings again, or my launcher, &c? Will it still be rooted? And are there any new features to look forward to?
I am not that sure I want A8.1 on Gemini, as on the other device I have the behaviour of 8.1 is a hell, this version of Android completely changes the notification API, many apps stops working notification including K-mail (well interested in airmail which is modified k-mail), there is very agressive power management, that is still killing any background app, you have to manually select apps that may live in the background, there is no way to set "disable wifi during sleep" as android wants wifi still on to track you etc. In the first place I'd like to know how the Gemini deals with those andriod oreo features.
