Android devs have always had to handle different screen sizes. Not the case for iPhone devs e.g. I have a game "Ridiculous Fishing" (from 2013) which is a mess layout-wise on my iPhone because it seemingly hardcoded some pixel values and used percentages for the others. They have a fixed version for Apple Arcade.
The first new resolution for an iPhone was 2012 which also saw the introduction of Auto Layout. The second new resolution was in 2014 which added size classes. It's entirely possible that the 2013 game was built before they actually started caring about this. This is a non-issue for almost all apps you're realistically going to encounter.
