These will be the following questions I will TRY and answer ... NO promises

1. Question: What was changed/improved hardware-wise since the hands-on event in germany? Are there units with final hardware?
How to test: Ask chen definitely.
Notes: If there are retail units, take a few screenshots/photos of the app drawer.

2. Question: Is the green dot on the capslock button actually an LED which lights up when capslock is enabled?
How to test: Play around with the keyboard. Ask Chen about it!

3. Question: Is the shift key 'sticky' by default - and other modifer keys too (ctrl/alt etc)?
How to test: Play around with the keyboard.
Notes: What I mean is if you are typing along press (and release) shift, does it affect the next letter you type.
Assuming yes, does it behave the same way with numbers (shift then 1 gets !)?
And assuming yes, does the Capslock LED (if any) stay lit after you press shift until you push the next key?

4. Question: Will the keyboard backlight be able to be controlled by software? Will there be an option to turn off the backlight when in a brightly lit area?
How to test: Play around with settings. Ask the F(x)tec team.

5. Question: Can I have auto-rotating disabled and be always in portait with keyboard closed and always landscape with keyboard opened?
How to test: Look around in settings and/or ask.

6. Question: What functions to the yellow arrow keys provide? Is there something similar to alt-gr?
How to test: Just ask I guess. If someone is familiar with a language that uses special accents on characters etc, they could change the layout setting and try.

7. Question: Does the escape key translate to back?
How to test: Ask about it. Be creative and think of a way to test.

8. Question: How is autofocus speed?
How to test: When half-pressing camera button, observe how long it takes until focus is locked (the camera app should give feedback).
Report subjective speed or capture it on video.

9. Question: How is the shutter lag?
How to test: Observe the time it takes between pressing shutter button fully down after already focussed, and the actual photo being taken.
Again report subjective speed or capture it on video.

10. Question: I want to see it in some jeans pocket.
Notes: Be free to substitute the jeans for other lower garnments if they aren't available.

11. Question: Does pro1 supports 4k output.
How to test: Probably not possible. Leviathan3k may bring 2k monitor, this is already a good test.

12. Question: Can you compare the speaker quality with other popular phones like the Pixel 3 and iPhones?
How to test: Both video/audio recording and subjective opinion are appreciated.
We are interested in loudness comparison as well as sound quality.

13. Question: How well does the sound from left and right speaker match?
How to test: I've made a test mp3 you can find here: http://matland.be/stereo.mp3 (WARNING On headphones this could be painful!)
Search YouTube for "stereo test" and look for a video that plays the same sound alternatingly left and right.
Alternatively you can be creative and find another test.

14. Question: How is the performance of the touchscreen at the edge?
How to test: Enable "Pointer location" option in Developer options, and swipe over the edge as straight as possible in different locations.
Alternatively install a drawing app. Note down if it behaves well following finger at the edge and/or take screenshots.

15. Will the screen stay open when the phone is held upside down?
Ex: using the phone while on your back in bed [there will be no beds there man, )

Some of the question on the list I believe have already been answers or discussed. Or are android specific which I will leave to someone else.

Cheers
