The problem occurs when I have a VirtualScroll list of 30+ items - the ActionSheet gets slower. I tried using a OnPush change detection strategy in Angular 4 but that didn't really work. I'm thinking the problem has to do with having a large DOM. Does that sound right? I also am loading 300px x 300px images in 80px x 80px squares. Will that slow it down? Is there some trick I can use to increase performance?\r\n\r\nI'm using a Samsung Galaxy S8+ and it seems like the app runs faster as a website in the Samsung browser than it does in the app. Maybe all the plugins are causing a slow down? Should I use Crosswalk?\r\n\r\n**Expected behavior:**\r\n60FPS transitions on mobile devices.\r\n"}}
