Lesson learned: Do not get fooled by the Surface Duo emulator in terms of performance and display

Hi team,

I just wanna help other developers to not get fooled as I got by using the emulator while developing apps for the Surface Duo.

My learnings in short

1. The performance of the actual device is astonishing, stouter-free scrolling and very smooth animations

2. Far less app crashes; apps on the emulator crashed a lot, on a real Duo this happens far less often mostly when changing from spanned to single screen or vice versa.

3. No more "blacked-out" screens; I have often the problem that one screen of the emulator gets black and maybe comes back to life after a couple of seconds, I cannot reproduce it on the actual device.

4. The display has very deep blacks but it is even in single screen posture not possible to reach all screen estate by one hand / finger.

5. Due to 4.) gestures are very important while developing an app. Out luck: the build in back navigation gesture.

6. Some postures like the vertical but spanned posture is more useful than I thought by using the emulator. Especially for reading long texts, I prefer this posture
