tl;dr add silence to your sound files if they’re too short. The release of my first ever mobile game Platform Pixels is coming up, so I’ve been testing it on as many devices as I can. I was confident after seeing it run on an old HTC One X (2012) but was saddened when I later saw it stutter on a more powerful Nexus 7 (2013). Then I noticed something. The stutter disappeared completely when I disabled the sound.
