I just tried running some tests on the Lumia 550 Windows Phone.
This phone is not powerful enough to give good performance on UWP projects.
Next I will try the Lumia 640 when that phone arrives I will post about the results.
I plan to work up the MS phone models till I figure out the minimum spec phone that will run my Chicken Wings game.
If you have performance reports from a phone please post up the info.
