I put in a start sound by YTETCHB (That how you spell it?) because Windows 11 Mobile would probably have a different bootup sound. Press and hold the on button for at least 3 secs to boot it up. (try a few times, buttons are small.)
Based on Addy Visual's design of Windows 11 Mobile https://scratch.mit.edu/discuss/topic/613408/ You will see that system.resolution/blueprints (a sprite) is 144x256. The resolution of a Lumia 950XL is exactly 10 times more than that. An image here is 10 times less than a Lumia 950XL.
