I figured, with the model being shown in the teaser probably being close to the final product, and also possibly reusing some components like the D-pad or the buttons from earlier Retroid models, I could probably perspective-warp the images shown in the teaser trailer to calculate the screen size.

So I hopped into Photoshop to do just that. I found a good still that showed the whole device and I adjusted it for perspective, making sure the screen is 4:3. (Obviously this looks odd -- I can't make a front perspective correct without majorly adjusting the image, which I think kind of defeats the point)

Then I found a Retroid Pocket 4 pro video from their Youtube channel and overlayed it to match the D-pad and face buttons.

D-pad match:

Face buttons match at the same scale: (See how the B and Y line up perfectly?)

and full images overlayed, anchored at the d-pad:

Then I drew a diagonal line over the Retroid Pocket 4 pro. We know that the RP4 is 4,7 inches. So by measuring the pixel length of the line we draw, we can calculate the screen size of the Mini. This came out at 327 pixels:

327 / 4,7 = 69.5744, this is the amount of px per inch. So now we take the measurement of our perspective-warped screenshot and measure its screen diagonal in pixels.

This came out at 247px (or 248px actually, in hindsight). Now we divide 247 by 69,5744 (our pixels per inch) and we get...

3.56 inch. Which I believe to be 3.5 inch, as it is based on a visual approximation of the d-pad and face buttons.

Of course, this is based on a warped screenshot approximation, so take it with a grain of salt.
